Terms of Use

Last updated: June 10, 2026

These Terms of Use govern your use of the Crux iOS application ("App"). By downloading or using the App, you agree to these terms.

1. Use of the App

Crux is a personal productivity app that helps you block distracting apps and build focus habits using Apple's Screen Time framework. You may use the App for your own personal, non-commercial purposes.

You agree not to:

• Reverse engineer, decompile, or disassemble the App
• Use the App for any unlawful purpose
• Attempt to circumvent or interfere with the App's blocking functionality

2. Subscriptions and Purchases

Crux offers auto-renewable subscriptions and a one-time lifetime purchase ("Crux Pro") that unlock full access to the App's features.

• Subscriptions are billed through your Apple ID and managed via the App Store.
• Subscriptions automatically renew unless cancelled at least 24 hours before the end of the current billing period.
• You can manage or cancel your subscription at any time in your Apple ID account settings.
• Free trial periods, if offered, are available to new subscribers only. Unused portions of a free trial are forfeited upon purchase.
• All payments are processed by Apple. We do not store your payment information.

3. Screen Time and Device Permissions

Crux uses Apple's Family Controls and Screen Time framework to enforce app blocking. You grant Crux permission to use these system features when you approve the Screen Time authorization prompt. All Screen Time data remains on your device and is never transmitted to us.

4. Intellectual Property

All content, design, and code in the App are owned by or licensed to us. You may not reproduce, distribute, or create derivative works without our prior written consent.

5. Disclaimer of Warranties

The App is provided "as is" without warranties of any kind. We do not guarantee that the App will be uninterrupted, error-free, or that app blocking will be 100% effective in all circumstances (e.g., after OS updates that may affect Screen Time behavior).

6. Limitation of Liability

To the fullest extent permitted by law, we are not liable for any indirect, incidental, or consequential damages arising from your use of the App.

7. Changes to Terms

We may update these Terms from time to time. Continued use of the App after changes constitutes acceptance of the new Terms.

8. Governing Law

These Terms are governed by the laws of the State of Israel, without regard to conflict of law principles.
