Please read these terms carefully. By downloading and using Zakat Book for Android, you agree to these Terms of Use. If you do not agree, please do not use the App.

1. Service Description

Zakat Book for Android ("App") is developed by LynxApps ("we," "us," "our") and provides tools to help Muslim users calculate and track their annual Zakat obligation. The App fetches live gold and silver market prices and performs on-device calculations. All personal and financial data is stored locally on your device.

2. Religious Guidance Disclaimer

Important: Zakat calculations provided by this App are for guidance and personal record-keeping only. They do not constitute a religious ruling (fatwa). For matters of religious compliance, please consult a qualified Islamic scholar or your local mosque. LynxApps makes no representation as to the religious acceptability of any specific calculation or output.

5. Data Handling & Privacy

Your financial data is never uploaded, transmitted, or shared — it is processed entirely on your device. We collect limited technical data (device info, crash reports, anonymous usage analytics, and advertising identifiers) through third-party services (Firebase, Google Mobile Ads). See our Privacy Policy for complete details.

6. Accuracy Disclaimer

The App uses live market data for gold and silver prices from third-party providers. While we strive for accuracy, LynxApps does not guarantee that prices, Nisab thresholds, or Zakat calculations are error-free or up to date. You are solely responsible for verifying your Zakat obligation with appropriate religious and financial advisors.

7. User Responsibilities

8. Disclaimers

The App is provided "AS IS" without warranties of any kind. We do not warrant that the App will be error-free, that market data will be continuously available, or that it will function on all devices or Android versions. Metal price feeds may be delayed or temporarily unavailable.

9. Limitation of Liability

To the fullest extent permitted by law, our total liability shall not exceed the amount you paid for subscriptions or in-app purchases in the 12 months preceding the claim, or $0 if you used only the free version. We are not liable for indirect or consequential damages, data loss, calculation errors, or religious non-compliance.

10. Intellectual Property

The App, including all code, design, graphics, and features, is owned by LynxApps and protected by copyright. All rights are reserved. You retain all rights to your personal data entered into the App. You may not copy, reproduce, modify, or use our branding without permission.

11. Termination

We may terminate or suspend your access if you violate these Terms, at our discretion, or as required by law. Upon termination, you must stop using the App and delete it from your device.

12. Third-Party Services

The App uses Google Play for subscriptions and billing, Firebase (by Google) for anonymous usage analytics and crash reporting, Google Mobile Ads for ad delivery, and third-party market data providers for live metal prices. These services are governed by their own terms and privacy policies.

13. Changes to These Terms

We may modify these Terms at any time. The latest version will always be available at /zakatbook-android/terms. Continued use of the App after changes constitutes acceptance of the updated Terms.
