Project OS Terms of Service

Last Updated: 5 October 2026

Version: 2026-10-05

These Terms of Service (“Terms”) govern your access to and use of Project OS, including our websites, web application, mobile or progressive web application, calculators, estimating tools, proposal tools, scheduling tools, project management tools, client portal features, accounting and tax export tools, emails, APIs, and any related services we provide (collectively, the “Service”).

Project OS is operated by Arden Systems LLC.

These Terms form a legally binding agreement between you and Arden Systems LLC doing business as Project OS(“Project OS,” “we,” “us,” or “our”).

You enter into these Terms when you expressly accept them through signup, an invitation or a subsequent acceptance prompt, or otherwise enter into an applicable service agreement. The Privacy Policy describes our data practices; acknowledging it is not blanket consent to new data uses. If you do not accept these Terms, do not use the protected Service. You may still read the legal notices and contact support for cancellation, billing questions or applicable privacy requests without accepting revised Terms.

1. Eligibility and Authority

You must be at least 18 years old and legally able to enter into contracts to use the Service.

If you use the Service on behalf of a company, contractor, organization, government entity, partnership, or other business, you represent that you have authority to bind that entity to these Terms. In that case, “you” and “your” refer to both you individually and the entity you represent.

You are responsible for ensuring that your use of the Service complies with all laws, regulations, licensing requirements, tax obligations, contract requirements, procurement rules, labor rules, and professional standards that apply to your work.

Launch subscriptions are offered to U.S. business customers. An employee or client invitation authorizes only the access granted by the relevant organization; it does not give that person authority to purchase, accept contracts or bind the organization beyond their actual authority.

2. Description of the Service

Project OS provides software tools for contractors and construction professionals, including some or all of the following:

• Project setup and project dashboards
• Client and project records
• Concrete calculators and construction calculators
• Construction activity estimating
• Production-rate based estimating
• Labor rate schedules and cost rollups
• Proposal generation, preview, export, and email delivery
• Project files, RFIs, FARs, change orders, QC records, and field activity tools
• Schedule Preview, Logic Network, CPM, Level III Gantt, crew demand, and related planning tools
• Project charts, dashboards, and reports
• Accounting and tax export tools
• Client portal or share-link functionality
• Integrations with third-party providers such as payment processors, email providers, accounting platforms, hosting providers, and storage providers

We may add, remove, modify, rename, or discontinue features at any time.

Features depend on the selected product, plan, role and current availability. Beta and preliminary tools, including Design Builder, require independent professional review and are not a certification of structural adequacy or code compliance. Quick and Conceptual outputs are planning estimates, not priced Detailed proposals ready for issuance.

3. No Professional, Engineering, Legal, Tax, or Financial Advice

Project OS is a software tool. It does not provide professional advice.

The Service may generate calculations, estimates, schedules, production-rate outputs, proposal documents, risk indicators, tax summaries, accounting exports, weather-related suggestions, or other business information. These outputs are for informational and planning purposes only.

You are solely responsible for reviewing, verifying, and approving all outputs before using them for bids, contracts, schedules, purchases, construction activities, safety planning, tax filings, accounting records, client communications, or business decisions.

Project OS does not replace:

• Licensed contractors
• Engineers
• Architects
• Accountants
• CPAs
• Tax professionals
• Attorneys
• Safety professionals
• Project managers
• Estimators
• Inspectors
• Local code officials
• Manufacturers’ instructions
• Contract documents
• Plans and specifications
• Applicable laws, codes, standards, permits, and regulations

You are responsible for confirming quantities, measurements, production rates, crew sizes, labor rates, material pricing, equipment pricing, markup, overhead, profit, taxes, schedules, project risks, and all other project assumptions.

4. Construction Estimates, Production Rates, and Calculations

The Service may include production-rate libraries, construction activities, man-hour calculations, labor rates, markup settings, cost summaries, and project estimates.

You understand and agree that all estimating outputs are dependent on the information entered, selected, imported, or configured by you or your users. Actual project costs, labor productivity, material quantities, crew performance, equipment usage, weather conditions, site conditions, subcontractor pricing, supplier pricing, permit requirements, inspection requirements, and market conditions may differ significantly from software-generated estimates.

Project OS does not guarantee:

• Accuracy of any estimate
• Suitability of any production rate for your project
• Actual labor productivity
• Actual project duration
• Availability or cost of materials
• Availability or cost of equipment
• Subcontractor pricing
• Project profitability
• Bid success
• Contract award
• Compliance with any bid requirement
• Compliance with any contract requirement

You are responsible for independently validating all estimates before submitting proposals, bids, invoices, schedules, or contracts.

5. Scheduling, Logic Network, CPM, Gantt, and Crew Planning

The Service may provide scheduling tools, including Schedule Preview, Logic Network, CPM calculations, Level III Gantt charts, crew demand charts, float calculations, and related planning features.

Scheduling outputs depend on user-entered durations, logic links, crew assumptions, activity selections, calendars, constraints, and project data. Project OS does not guarantee that a generated schedule is feasible, contract-compliant, resource-loaded, risk-adjusted, or suitable for submission to an owner, general contractor, government entity, or any other party.

You are responsible for reviewing and validating:

• Activity durations
• Logic relationships
• Critical path
• Float values
• Crew assumptions
• Resource availability
• Sequencing
• Schedule constraints
• Weather assumptions
• Contract schedule requirements
• Delay impacts
• Updates and actual progress

The Service is a planning aid and does not replace professional scheduling judgment.

6. Proposals, Client Communications, and Shared Links

The Service may allow you to create, preview, download, share, and email proposals or other project documents.

You are solely responsible for reviewing all proposal content before sending it to any client, owner, contractor, subcontractor, supplier, or third party. This includes reviewing pricing, scope of work, exclusions, assumptions, dates, client information, business information, terms, taxes, attachments, public links, and any generated text.

If you send proposals or other communications through the Service, you represent that:

• You have permission to contact the recipient
• The recipient information is accurate
• The communication is lawful
• The communication does not violate spam, privacy, consumer protection, procurement, or contract laws
• You have authority to send the communication on behalf of your business

Shared links, proposal links, client portal links, or public tokens may allow third parties to view certain information. You are responsible for deciding what to share and with whom. Do not share confidential, sensitive, regulated, or private information unless you are authorized to do so.

We may track delivery, open, click, and status events for emails or shared links where supported by our service providers.

Review a document and your authority before any signature, acceptance or public decision. A public decision concerns the identified document, not acceptance of every other project record. Public links are bearer capabilities: protect them, share only intended content and revoke them when no longer needed. Already-issued field attachment downloads can remain usable for up to 15 minutes; client document downloads can remain usable for up to five minutes. Recipient downloads or third-party copies are not recalled by revocation.

7. Client Portal and Third-Party Access

The Service may allow you to invite clients, employees, subcontractors, team members, or other third parties to view or interact with certain project information.

You are responsible for:

• Selecting the correct recipient
• Assigning appropriate access
• Removing access when no longer needed
• Ensuring client or third-party access complies with your contracts and privacy obligations
• Ensuring information shared through the Service is appropriate and accurate

We are not responsible for harm caused by your decision to share project information, proposals, files, estimates, schedules, or communications with any person or entity.

8. Accounting and Tax Export Tools

The Service may provide accounting and tax-related export features, including year-end summaries, Schedule C style summaries, CPA workbooks, revenue exports, expense exports, QuickBooks-related exports, TurboTax helper exports, and other tax or accounting reports.

These features are business record tools only. They are not tax advice, accounting advice, legal advice, financial advice, or a substitute for a CPA, accountant, bookkeeper, tax professional, or attorney.

Any “Schedule C style” summary is not an official IRS form. Any “TurboTax helper export” or similarly named export is intended only to assist with data entry or review where practical. We do not guarantee that any export will be accepted by TurboTax, QuickBooks, Intuit, the IRS, any state taxing authority, any CPA, or any accounting platform.

You are solely responsible for:

• Reviewing all exported data
• Confirming the correct tax year
• Confirming cash or accrual treatment
• Confirming revenue recognition
• Confirming expense categorization
• Confirming deductible expenses
• Confirming business entity treatment
• Maintaining required books and records
• Filing accurate tax returns
• Paying taxes, fees, penalties, and interest
• Consulting qualified professionals

Project OS does not guarantee tax savings, tax compliance, audit protection, accounting accuracy, or acceptance by any third-party software or tax authority.

9. Third-Party Services and Integrations

The Service may use or integrate with third-party services, including but not limited to:

• Stripe or other payment processors
• Resend or other email providers
• Supabase or other database/authentication providers
• Netlify or other hosting providers
• Intuit, QuickBooks, or other accounting platforms
• Mapping, weather, storage, analytics, or notification providers
• App stores, browsers, operating systems, or device platforms

Your use of third-party services may be subject to separate terms, privacy policies, fees, limitations, and availability. We are not responsible for third-party services, outages, data handling, security incidents, pricing changes, API changes, denied integrations, rejected exports, or discontinued functionality.

We may modify, suspend, or remove integrations if a third-party provider changes its service, terms, pricing, security requirements, API access, or approval status.

Available optional features can also use OpenAI for text assistance, ElevenLabs for audio transcription, Google Cloud for application services, Cloudmersive or a configured document scanner for malware inspection, and Microsoft, Google or mapping providers for customer-enabled integrations. The Privacy Policy explains the information involved. Feature availability does not mean every integration is enabled for every customer.

10. Accounts and Security

You may need an account to use certain features. You agree to provide accurate, current, and complete information and to keep it updated.

You are responsible for:

• Maintaining the confidentiality of your login credentials
• Securing your devices
• Controlling access by your employees, clients, subcontractors, and team members
• All activity under your account
• Promptly notifying us of unauthorized access or suspected security issues

We are not liable for losses caused by unauthorized use of your account unless caused by our gross negligence or willful misconduct.

We may require multi-factor authentication, password resets, email verification, or other security measures.

11. Organizations, Team Members, and Permissions

If your account includes team features, you are responsible for managing users, roles, permissions, invitations, and access levels.

You are responsible for all actions taken by users you invite or authorize. You agree to remove access for users who leave your organization or no longer need access.

Certain administrative features may be limited to account owners, admins, or authorized roles.

12. Subscriptions, Trials, Billing, and Payment

Some features require a paid subscription. The selected plan, price, currency, billing interval, feature limits and applicable taxes are presented in the relevant pricing and checkout flow. Paid subscriptions renew automatically until canceled and are billed in advance for the selected monthly or annual period.

Project OS offers an eligible account one 30-day in-app trial. No card is required, and the trial does not automatically convert to a paid subscription or charge you when it ends. Starting a paid subscription requires a separate checkout action. Trial availability, permitted use and feature limits are shown in the app; we may restrict abuse.

By confirming a paid purchase, you authorize the disclosed subscription charges and renewals through our payment processor. A prorated upgrade at the current billing interval takes effect only after successful payment. A failed upgrade does not remove access already paid for. Downgrades and changes between monthly and annual billing, in either direction, take effect at renewal.

If a renewal payment fails, paid access does not receive an additional grace period beyond the already-paid period. An unrelated standalone or manual invoice does not suspend an otherwise paid subscription. Support, cancellation assistance and applicable privacy-request contact remain available.

Seats, add-ons, storage, credits and other usage limits depend on the selected offer. Any separate charge or expiry must be disclosed in its purchase flow. Manage Billing and the app settings provide supported billing actions; contact support if an action is unavailable. Changes to pricing or material subscription terms will be communicated as required by law.

13. Cancellation and Refunds

You may cancel through the billing tools provided or contact support for help. Cancellation takes effect at the end of the current paid period, and already-paid access continues until that period ends unless a separate lawful suspension applies. Cancellation stops future subscription renewals; it is not itself a request to erase company data.

We do not provide routine refunds or credits for unused time, unused features, partial periods or downgrades. We will correct billing errors and honor refunds and other remedies required by applicable law. Contact support with the disputed charge and account information; do not send complete payment-card details.

If you decline revised Terms or cannot access the app, you can still request cancellation or billing assistance at support@ardenprojectos.com. No support response time is guaranteed. We aim to respond promptly.

14. Taxes

Arden subscription charges are separate from your own business, project, income, payroll and customer-payment tax obligations. Checkout may calculate applicable subscription sales tax using Stripe Tax and the customer information provided. The final checkout or invoice shows the amount charged. Automatic calculation does not replace tax registration, filing or professional advice.

You remain responsible for the tax treatment of your construction estimates, invoices and business activity. In-app tax calculations and exports are recordkeeping aids, not a determination that your business complies with every applicable tax rule. Where Stripe Connect or another customer-payment integration is available, its connected-account charges and responsibilities are separate from the Arden subscription.

15. User Content and Project Data

“User Content” means information, files, text, data, images, estimates, proposals, project records, client records, schedules, RFIs, FARs, change orders, QC records, communications, and other materials you upload, enter, generate, store, send, or otherwise provide through the Service.

You retain ownership of your User Content. You grant us a worldwide, non-exclusive, royalty-free license to host, store, process, transmit, display, reproduce, modify, and use your User Content solely as necessary to provide, secure, improve, support, and operate the Service.

You represent and warrant that you have all rights necessary to submit and use your User Content and that your User Content does not violate laws, contracts, privacy rights, intellectual property rights, or third-party rights.

You are responsible for backing up important records. While we may provide storage and export tools, we do not guarantee that the Service is your permanent archive or sole recordkeeping system.

16. Confidentiality

You may upload or generate confidential business information through the Service. We will use reasonable efforts to protect your information consistent with our Privacy Policy and security practices.

You are responsible for deciding what information to upload, share, email, export, or make available through public links or client portals.

Do not upload information that you are not authorized to store or process through the Service.

17. Privacy

The Privacy Policy describes the information collected and processed when you use the Service, including optional recording, AI assistance, uploads and integrations. You must have authority and any legally required notices or permissions before submitting information about employees, clients, subcontractors or other people.

Acceptance of these Terms and acknowledgment of the Privacy Policy do not authorize materially different data uses or marketing use of your name or logo. Where a new use requires separate consent, we will obtain that permission before introducing it.

18. Acceptable Use

You agree not to use the Service to:

• Violate any law, regulation, contract, court order, or third-party right
• Submit false, misleading, fraudulent, unlawful, defamatory, obscene, harassing, abusive, or harmful content
• Send spam, unsolicited commercial email, or unlawful communications
• Impersonate any person or entity
• Access another user’s account or data without authorization
• Interfere with or disrupt the Service
• Attempt to probe, scan, test, or bypass security controls
• Upload malware, viruses, or harmful code
• Reverse engineer, decompile, copy, scrape, or misuse the Service
• Use automated systems to access the Service without permission
• Resell, sublicense, or commercially exploit the Service except as expressly allowed
• Use the Service to build a competing product
• Violate export control or sanctions laws
• Upload regulated information unless you are authorized and the Service is appropriate for that use

We may suspend or terminate accounts that violate this section.

19. Email and Messaging

The Service may allow you to send emails or messages to clients, team members, or third parties. You are responsible for ensuring that your messages comply with applicable laws, including anti-spam, privacy, and consumer protection laws.

We may log email metadata such as recipient, sender, subject, template, delivery status, open status, click status, bounce status, and related event data where supported.

We may block or limit sending to addresses that bounce, complain, unsubscribe, or appear abusive.

We do not guarantee email delivery, inbox placement, open rates, response rates, or client acceptance.

20. Files, Exports, and Downloads

The Service may allow you to export PDFs, spreadsheets, CSV files, ZIP files, proposal packages, accounting packages, tax packages, and other files.

You are responsible for reviewing exported files before using, sending, filing, or relying on them.

Exports may depend on browser settings, third-party libraries, available data, formatting limitations, and device capabilities. We do not guarantee that exported files will meet the requirements of any client, owner, accountant, government agency, software platform, or third party.

Use the export formats actually provided for the feature concerned. A PDF, CSV or feature-specific download is not a complete account export. For broader exports or account-deletion requests, contact support; identity and company authority must be verified, and lawful retention exceptions may apply.

21. Mobile, PWA, Offline, and Device Features

The Service may be accessible through mobile browsers, installed progressive web app features, or device-specific capabilities such as sharing, notifications, storage, camera, or files.

Mobile and device features may depend on your device, browser, operating system, permissions, network connection, and third-party platforms.

We do not guarantee uninterrupted mobile functionality, offline availability, push notifications, share previews, file access, or device-specific behavior.

22. Beta Features and Experimental Tools

We may offer beta, preview, experimental, AI-assisted, or early-access features. These features may be incomplete, inaccurate, unstable, unavailable, or changed without notice.

You should not rely on beta or experimental outputs without independent review.

We may disable beta features at any time.

23. Artificial Intelligence and Automated Suggestions

If the Service includes AI-assisted features, automation, suggestions, summaries, sequencing recommendations, proposal text, classifications, or similar tools, those outputs are generated based on available data and may be inaccurate, incomplete, or inappropriate for your project.

You are responsible for reviewing and approving AI-assisted or automated outputs before use.

We do not guarantee that AI-assisted outputs are correct, code-compliant, contract-compliant, safe, complete, or suitable for any bid, proposal, schedule, tax filing, or business decision.

24. Intellectual Property

The Service, including software, design, user interface, workflows, templates, documentation, graphics, logos, trademarks, trade names, data structures, and other materials we provide, is owned by Project OS or its licensors and is protected by intellectual property laws.

You may not copy, modify, distribute, sell, lease, sublicense, reverse engineer, or create derivative works from the Service except as expressly allowed by these Terms.

All rights not expressly granted are reserved.

25. Feedback

If you provide ideas, suggestions, bug reports, feature requests, comments, designs, workflows, or other feedback, you grant us a perpetual, worldwide, irrevocable, royalty-free right to use, modify, commercialize, and incorporate that feedback without compensation or obligation to you.

26. Publicity

You represent that you have authority to provide uploaded business names and logos. We may display them in your workspace, proposals, reports and other outputs as needed to provide your service.

Use of your name, logo or testimonial in Arden Systems advertising, public customer lists or promotional material requires separate, explicit opt-in. You may withdraw that marketing permission by contacting support. Withdrawal stops future controlled promotional use and we will remove it from channels we control; it does not recall already-distributed third-party copies.

27. DMCA and Copyright Complaints

If you believe content in the Service infringes your copyright, contact us with:

• Your name and contact information
• Identification of the copyrighted work
• Identification of the allegedly infringing material
• A statement that you have a good-faith belief the use is unauthorized
• A statement under penalty of perjury that the information is accurate
• Your physical or electronic signature

Send notices to the contact email listed below.

28. Availability, Outages, and Data Responsibility

Project OS is provided on an “AS IS” and “AS AVAILABLE” basis. We do not guarantee that the Service will be uninterrupted, timely, secure, error-free, or continuously available. Access to the Service may be affected by maintenance, outages, internet or network issues, database interruptions, third-party provider failures, security events, or other circumstances beyond our control.

While Project OS may perform routine backups and use commercially reasonable safeguards, you are ultimately responsible for maintaining independent, duplicate records of your critical business and project information. This includes, without limitation, estimates, proposals, contracts, change orders, RFIs, FARs, schedules, project records, client communications, documents, exports, accounting records, and other business-critical data.

You should not rely on Project OS as your only copy of information needed for bid deadlines, contract performance, legal compliance, accounting, tax records, client obligations, or business continuity. You should export or maintain duplicate records as needed for deadlines, bids, contracts, accounting, legal, or compliance purposes.

We may modify, suspend, restrict, or discontinue any part of the Service at any time.

29. Contractor Deadlines, Bids, and Project Outcomes

You are responsible for verifying all estimates, quantities, pricing, schedules, deadlines, bid submissions, contract documents, project records, and exported materials before relying on them. Project OS is a project management and estimating tool. We do not guarantee bid submission, contract award, profitability, deadline compliance, project performance, or any particular business outcome.

30. Suspension and Termination

We may suspend or terminate your access if:

• You violate these Terms
• You fail to pay fees
• Your payment method fails
• Your use creates risk or legal exposure
• Your account appears fraudulent, abusive, or insecure
• We are required to do so by law or third-party provider requirements
• We discontinue the Service or a feature

You may stop using the Service at any time. Termination does not relieve you of amounts owed or obligations that survive termination.

After termination, we may delete, retain, archive, or restrict access to account data according to our policies, legal obligations, backup practices, and Privacy Policy.

31. Disclaimers

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE.”

TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, RELIABILITY, AVAILABILITY, SECURITY, AND ERROR-FREE OPERATION.

WE DO NOT WARRANT THAT:

• THE SERVICE WILL MEET YOUR REQUIREMENTS
• THE SERVICE WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE
• ESTIMATES, SCHEDULES, REPORTS, EXPORTS, TAX SUMMARIES, OR PROPOSALS WILL BE ACCURATE
• DEFECTS WILL BE CORRECTED
• DATA WILL NEVER BE LOST
• EMAILS WILL BE DELIVERED
• THIRD-PARTY SERVICES WILL REMAIN AVAILABLE
• OUTPUTS WILL COMPLY WITH LAWS, CODES, CONTRACTS, TAX RULES, OR PROFESSIONAL STANDARDS

32. Exclusion of Consequential Damages

To the maximum extent permitted by law, in no event shall Project OS, its owners, officers, employees, contractors, affiliates, service providers, or licensors be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, including without limitation loss of profits, loss of revenue, loss of business opportunity, loss of bids or contracts, loss of data, loss of use, loss of goodwill, business interruption, or other intangible losses, whether based on warranty, contract, tort, negligence, strict liability, or any other legal theory, even if Project OS has been advised of the possibility of such damages.

33. Limitation of Liability

To the maximum extent permitted by law, Project OS’s total liability for any claim arising out of or relating to the Service shall not exceed the greater of: (a) the total amount paid by you to Project OS for use of the Service during the twelve (12) months immediately preceding the event giving rise to the claim; or (b) one hundred U.S. dollars ($100).

This limitation applies to all claims in the aggregate, including claims related to service outages, data loss, delayed access, billing, errors, omissions, interrupted service, or use of the Service. Some jurisdictions do not allow certain limitations of liability, so these limitations apply only to the maximum extent permitted by applicable law.

34. Indemnification

You agree to defend, indemnify, and hold harmless Project OS and its owners, officers, directors, employees, contractors, affiliates, agents, suppliers, and licensors from and against all claims, damages, losses, liabilities, costs, and expenses, including reasonable attorneys’ fees, arising out of or related to:

• Your use of the Service
• Your User Content
• Your estimates, proposals, schedules, exports, emails, or client communications
• Your construction work, contracts, bids, projects, or business operations
• Your tax, accounting, payroll, labor, licensing, or regulatory obligations
• Your violation of these Terms
• Your violation of law
• Your violation of third-party rights
• Use of the Service by your employees, clients, subcontractors, invitees, or authorized users

35. Dispute Resolution

Please contact us with a description of a dispute and the relief requested so we can attempt an informal resolution. This does not prevent a timely filing, urgent relief, an eligible small-claims case or exercise of non-waivable statutory rights.

These Terms do not require mandatory arbitration and do not impose an arbitration opt-out, jury-trial waiver or class-action waiver. After a dispute arises, both parties may separately agree to mediation or arbitration. Without that agreement, disputes may be resolved in the appropriate courts under Section 36.

36. Governing Law and Venue

These Terms are governed by the laws of the State of New Mexico, without regard to conflict-of-law rules, except where applicable law requires otherwise.

Subject to non-waivable statutory rights and eligible small-claims access, proceedings may be brought in the appropriate New Mexico state courts in the county connected to Arden Systems LLC’s registered or principal business location, or in the U.S. District Court for the District of New Mexico where federal jurisdiction exists. Each party consents to jurisdiction and venue in those courts to the extent permitted by law.

37. Export Control and Sanctions

You may not use the Service if you are located in, organized under the laws of, or ordinarily resident in a country or region subject to comprehensive U.S. sanctions, or if you are listed on any U.S. government restricted-party list.

You agree not to use, export, re-export, or transfer the Service in violation of U.S. export control or sanctions laws.

38. Government Use

The Service is commercial computer software. If used by or on behalf of a government entity, the Service is provided with only the rights granted to other users under these Terms, unless a separate written agreement states otherwise.

39. Changes to These Terms

We may update these Terms and identify the published version and date. Routine corrections do not automatically require renewed acceptance. For material changes to contractual rights, we will provide clear notice and require renewed acceptance before applying the revised Terms to continued protected use. Where practicable, notice will be given 30 days in advance, with an opportunity to export supported records and cancel. Applicable legal requirements and rights remain controlling.

If you decline, do not continue protected use under the revised Terms. The legal pages and support contact remain available for cancellation, billing questions and applicable privacy requests. Prior acceptance records are retained separately from later acceptance; acknowledging a privacy notice is not permission for every future data use.

40. Assignment

You may not assign or transfer these Terms or your account without our prior written consent.

We may assign these Terms in connection with a merger, acquisition, financing, reorganization, sale of assets, change of control, or operation of law.

41. Severability

If any provision of these Terms is found invalid, illegal, or unenforceable, that provision will be modified to the minimum extent necessary to make it enforceable, or removed if modification is not possible. The remaining provisions will remain in full force and effect.

42. No Waiver

Our failure to enforce any provision of these Terms does not waive our right to enforce that provision later.

43. Entire Agreement

These Terms, together with the Privacy Policy, any applicable order form, subscription terms, plan terms, or written agreement between you and us, make up the entire agreement between you and Project OS regarding the Service.

If there is a conflict between these Terms and a separate written agreement signed by both parties, the signed agreement controls to the extent of the conflict.

44. Contact Information
