Terms of Use

Please read these Terms of Use (“Terms”) carefully before using Blink Tracker (“the App”) developed by Octo8 (“we”, “us”, or “our”).

1. Acceptance of Terms

By downloading, installing, or using Blink Tracker, you agree to be bound by these Terms. If you do not agree, do not use the App.

2. Description of the App

Blink Tracker is a macOS menu bar utility that monitors your blink rate using your Mac’s camera and Apple’s Vision framework. It provides real-time blink statistics and sends local notification reminders when your blink rate drops.

3. License

Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to use Blink Tracker on any Mac that you own or control, in accordance with the Apple Media Services Terms and Conditions.

4. Medical Disclaimer

Blink Tracker is a wellness utility, not a medical device. The App:

  • Is not intended to diagnose, treat, cure, or prevent any disease or medical condition
  • Does not provide medical advice
  • Should not be used as a substitute for professional medical care
  • May not detect all blinks with 100% accuracy

If you experience persistent dry eyes, eye strain, headaches, or vision changes, consult an eye care professional. The blink detection accuracy depends on lighting conditions, camera quality, face position, and other environmental factors.

5. Camera Usage

Blink Tracker requires camera access to function. By granting camera permission, you acknowledge that:

  • The camera is used solely for on-device blink detection
  • No video is recorded, stored, or transmitted
  • The macOS camera indicator (green dot) will be visible while monitoring is active
  • You can revoke camera permission at any time through System Settings

6. Acceptable Use

You agree not to:

  • Reverse engineer, decompile, or disassemble the App
  • Use the App for any unlawful purpose
  • Redistribute, sublicense, or resell the App
  • Remove any copyright or proprietary notices from the App

7. Intellectual Property

Blink Tracker, including its name, logo, design, and code, is the intellectual property of Octo8. All rights not expressly granted in these Terms are reserved.

8. Limitation of Liability

To the maximum extent permitted by applicable law, Octo8 shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including but not limited to:

  • Loss of data
  • Loss of profits
  • Personal injury or health effects
  • Interruption of service

arising out of or related to your use of Blink Tracker. Since the App operates entirely offline with no data collection, the risk of data-related harm is minimal.

9. Disclaimer of Warranties

Blink Tracker 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.

10. Termination

We reserve the right to modify, suspend, or discontinue the App at any time without notice. You may stop using the App at any time by uninstalling it.

11. Changes to These Terms

We may update these Terms from time to time. The updated version will be posted at this URL with a revised “Last Updated” date. Continued use of the App after changes constitutes acceptance of the new Terms.

12. Governing Law

These Terms shall be governed by and construed in accordance with the laws applicable in your jurisdiction, without regard to conflict of law principles.
