CheckStay Pro

Terms of Service

Last updated: March 15, 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 & Backups

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. Please review our Privacy Policy for details on how we store and sync your data.

Data loss disclaimer. You are solely responsible for maintaining your own backups of all data stored in CheckStay Pro. Hawser Labs does not guarantee that cloud-synced data will be free from loss, corruption, or accidental deletion. We strongly recommend exporting or backing up your data regularly. We are not liable for any data loss that occurs during your use of the App.

5. Payments & Refund Policy

Pro license and Sync subscription purchases are processed through our payment provider (currently Stripe). All standard payment terms of that provider apply.

Refunds. You may request a full refund within 14 days of your original purchase date by contacting us at hello@hawserlabs.com. After that 14-day window, purchases are considered final and non-refundable, except where required by applicable law. We reserve the right to grant refunds outside this window at our sole discretion.

If you experience a technical issue preventing activation, contact us and we will work to resolve it before processing any refund.

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. Your use of the App is entirely at your own risk.

No professional advice. CheckStay Pro is a general-purpose organizational tool only. Nothing in the App or its outputs constitutes legal, financial, medical, or other professional advice. Do not rely on the App for decisions requiring qualified professional judgment.

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, even if we have been advised of the possibility of such damages.

Liability cap. In no event will our total cumulative liability to you for all claims arising out of or relating to these Terms or your use of the App exceed the total amount you actually paid to Hawser Labs for the App in the twelve (12) months immediately preceding the event giving rise to the claim, or USD $50, whichever is greater.

9. Modifications & Discontinuation

Hawser Labs reserves the right, at any time and without prior notice, to:

  • Modify, update, or remove features of the App.
  • Discontinue the App or any associated services (including cloud sync).
  • Change pricing for future purchases or subscription renewals.

We will make reasonable efforts to provide advance notice of material changes that affect paid subscribers. Your continued use of the App after such changes constitutes acceptance. If the App is discontinued, your locally-stored data will remain on your device; we are not responsible for loss of access to cloud-synced data following discontinuation.

10. 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 11 survive termination.

11. 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.

12. 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.
