Last Updated: April 9, 2026

1. Acceptance of Terms

These Terms of Use (“Terms”) constitute a legally binding agreement between you and Farid Rehila (“we”, “us”, “our”, or “Developer”) regarding your use of the Chrona mobile application (“App”). By downloading, installing, accessing, or using the App, you agree to be bound by these Terms. If you do not agree to these Terms, do not use the App.

2. Description of Service

Chrona is a mobile application designed to help you limit access to selected apps on your device and unlock usage time by completing push-ups.

The App may include, among other things:

• Tools to block or restrict access to apps you choose
• A system that grants usage time based on completed push-ups
• On-device push-up detection using your phone camera
• Time tracking related to earned and spent app access
• Premium features available through subscription

One push-up is currently intended to grant one minute of app access time, but we may adjust product features, limits, or calculations over time.

3. Eligibility

You must be at least 13 years of age (or the applicable age of digital consent in your jurisdiction) to use this App. By using the App, you represent and warrant that you meet this age requirement. If you are under 18, you represent that you have obtained parental or guardian consent to use this App.

4. License Grant and Restrictions

4.1 License

Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to download, install, and use the App on devices you own or control, solely for your personal, non-commercial use.

4.2 Restrictions

You agree NOT to:

• Modify, reverse engineer, decompile, disassemble, or create derivative works of the App
• Remove, alter, or obscure any proprietary notices from the App
• Use the App for any illegal, harmful, fraudulent, or unauthorized purpose
• Attempt to gain unauthorized access to any part of the App or its systems
• Use automated scripts, bots, emulators, or similar tools to access or manipulate the App
• Interfere with or circumvent the App’s blocking logic, motion detection, subscription logic, or security features
• Reproduce, distribute, publicly display, or create derivative works from the App, except as permitted by law
• Sell, rent, lease, sublicense, or transfer your rights to use the App

5. Device Permissions, Subscriptions, and Data

5.1 Permissions

Certain features require access to device permissions, including camera access and operating-system permissions needed to block or limit apps. If you deny or revoke required permissions, some features may not function properly.

5.2 Subscription Management

The App uses RevenueCat to help manage subscription status and in-app purchase entitlements. Subscription purchases are processed through Apple or Google, not directly by us.

5.3 App Data

The App may process onboarding information and usage data needed to operate, improve, secure, and measure the App. We design Chrona so that push-up detection occurs locally on the device. We do not record or store the camera videos used for push-up detection.

We may store or process technical, analytics, and subscription-related data, including pseudonymous identifiers, but we do not intend to associate such data with your real-world identity unless required for a specific lawful purpose.

5.4 Accuracy of Information

You agree to provide accurate, current, and complete information when using onboarding or payment-related features, and not to intentionally provide misleading information.

6.3 Free Trials

We may offer free trial periods for Premium Features. You may be charged once the trial period ends unless you cancel before the trial expires. We reserve the right to modify or cancel free trial offers at any time.

6.4 Changes to Pricing

We reserve the right to change subscription pricing at any time. For existing subscribers, we will provide notice before any price increase takes effect where required by applicable law or platform rules.

6.5 Free Trial

We offer a free 7-day trial to new users who sign up for a yearly subscription. Once your trial ends, your subscription will automatically start unless you cancel before the end of the trial period.
