CheckStay Pro

Terms of Service

Last updated: March 14, 2026

1. Acceptance of Terms

These Terms of Service (“Terms”) are a legal agreement between you and Hawser Labs (“we,” “us,” or “our”), a company located in Ventura County, California. By downloading, installing, or using CheckStay Pro (“the App”), you agree to be bound by these Terms. If you do not agree, do not use the App.

2. License Grant

2a. Free Tier

We grant you a personal, non-exclusive, non-transferable, revocable license to use CheckStay Pro at no charge within the following limits: up to 2 active projects and up to 6 contacts. These limits may change with reasonable notice.

2b. Pro License

Purchase of a Pro license key grants you a personal, non-exclusive, non-transferable, perpetual license to use CheckStay Pro on a single Mac (the machine on which the key is activated), with no usage limits. The license key is locked to one machine via a hardware fingerprint at the time of activation. You may contact us to transfer your license to a new machine.

2c. Restrictions

You may not:

  • Reverse engineer, decompile, or disassemble the App.
  • Redistribute, sublicense, rent, or sell the App or your license key.
  • Remove or alter any proprietary notices or labels in the App.
  • Use the App for any unlawful purpose.

3. AI Assistant

The App’s AI Assistant allows you to connect third-party AI providers (OpenRouter, Google Gemini, or a local Ollama instance) using API keys you supply. You are solely responsible for:

  • Obtaining and managing your own API keys.
  • Any costs charged by those providers for API usage.
  • Compliance with the terms of service of the AI provider you select.
  • The content of messages sent to and received from AI providers through the App.

We are not responsible for the outputs, accuracy, availability, or privacy practices of any third-party AI provider.

4. Your Data

You retain full ownership of all project data, contacts, and other content you create in the App. We do not claim any intellectual property rights over your content. You are responsible for maintaining backups of your data. Please review our Privacy Policy for details on how we store and sync your data.

5. Payments & Refunds

Pro license purchases are processed through our payment provider. All sales are final. If you experience a technical issue preventing activation, contact us at hello@hawserlabs.com and we will work to resolve it. We reserve the right to issue refunds at our sole discretion.

6. Intellectual Property

The App, including its code, design, branding, and all related materials, is owned by Hawser Labs and is protected by copyright and other intellectual property laws. Nothing in these Terms transfers any intellectual property rights to you other than the limited license described in Section 2.

7. Disclaimer of Warranties

The App is provided “as is” and “as available” without warranties of any kind, express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the App will be error-free, uninterrupted, or that any defects will be corrected.

8. Limitation of Liability

To the fullest extent permitted by applicable law, Hawser Labs and its officers, employees, and agents will not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of data, profits, or goodwill, arising out of or in connection with your use of the App. In no event will our total liability to you exceed the amount you paid for your Pro license in the twelve months preceding the claim.

9. Termination

We may suspend or terminate your license if you materially breach these Terms. Upon termination, you must cease using the App and may delete it from your device. Sections 4, 6, 7, 8, and 10 survive termination.

10. Governing Law & Disputes

These Terms are governed by the laws of the State of California, without regard to its conflict of law provisions. Any dispute arising under these Terms will be resolved exclusively in the state or federal courts located in Ventura County, California, and you consent to personal jurisdiction there.

11. Changes to These Terms

We may update these Terms from time to time. We will update the “Last updated” date above and, for material changes, provide notice via the App or by email if we have your address on file. Continued use of the App after changes are posted constitutes acceptance of the revised Terms.
