Tajwid is an educational application for learning **Tajwid** (rules of Quranic recitation). The App is designed to work primarily with content stored on your device. We use limited analytics and subscription services as described below. We do not require you to create an account in the App to use the core experience described in the store listing.
---
- **Purchases:** If you subscribe or make in-app purchases, **Apple** (on iOS) or **Google** (on Android) process payment and provide us or our service providers with transaction-related information needed to unlock premium content (for example, subscription status and identifiers used to link your purchase to the App). We do not receive your full payment card details.
- **App analytics (Firebase / Google):** On native builds of the App (not when running inside certain development clients), we may use **Google Firebase Analytics** to collect **usage analytics**, such as **screen views** (which parts of the App you open). This helps us understand how the App is used and improve it. Firebase may collect device and app information consistent with [Google’s Firebase Privacy Information](https://firebase.google.com/support/privacy) and [Google’s Privacy Policy](https://policies.google.com/privacy).
- **Device and app technical data:** Your device type, operating system version, app version, language/locale, and similar technical data may be processed by our analytics and subscription providers as part of providing their services.
- **Language preference:** The interface language you choose (or the default based on your device) may be stored **locally on your device** so the App can remember your choice when you open it again.
We do not ask you to provide your name, email address, or phone number **inside the App** for a user account. We do not deliberately collect sensitive categories of data beyond what is necessary for the App to function and as described here.
---
We use **RevenueCat** (RevenueCat, Inc.) to manage subscriptions and entitlements. RevenueCat processes information related to purchases and your App installation in order to determine subscription status, restore purchases, and similar functions. For details, see [RevenueCat’s Privacy Policy](https://www.revenuecat.com/privacy).
Actual payments are handled by **Apple App Store** or **Google Play**; their privacy policies apply to payment processing.

The App may rely on third parties including:
| Service | Purpose | Privacy information |
|----------------|----------------------------------------------|----------------------------------------------------------|
| Google Firebase | App infrastructure and analytics | https://firebase.google.com/support/privacy |
| RevenueCat | Subscription and entitlement management | https://www.revenuecat.com/privacy |
| Apple | App distribution and payments (iOS) | https://www.apple.com/legal/privacy/ |

We do not control how these third parties process data beyond our configuration of their SDKs; please read their policies.
---
We may share information with service providers who assist on our behalf (such as analytics and subscription management), as needed to operate the App, and when required by law or to protect rights and safety.
We do **not** sell your personal information as “sale” is commonly defined under US state privacy laws (as a sale for monetary or other valuable consideration).
---
We retain information only as long as needed for the purposes described in this policy, including legal, accounting, and dispute resolution needs. Analytics data may be retained according to the settings and policies of **Firebase/Google**. Purchase records are retained by app stores and our subscription provider as per their policies.
---
We use reasonable technical and organizational measures appropriate to the nature of the services. No method of transmission or storage is 100% secure.
---
The App may be suitable for learners of various ages. We do not knowingly collect personal information from children under **13** (or the age required in your jurisdiction) for marketing or unnecessary purposes. If you believe we have collected such information, contact us at **tools.deen@gmail.com** and we will seek to delete it promptly.
Parents and guardians should supervise children’s use of the App and device settings (including app store accounts).
---
If you are outside the country where our service providers are located (for example the United States), your information may be transferred to and processed in other countries where privacy laws may differ.
---
Depending on where you live, you may have rights to:
- Access, correct, or delete certain personal information
- Object to or restrict certain processing
- Data portability
- Withdraw consent where processing is based on consent
- Lodge a complaint with a supervisory authority
To exercise rights that we can fulfill directly, contact **tools.deen@gmail.com**. For purchase history and payment data, you may need to use **Apple** or **Google** account tools. For analytics tied to Google, you may use Google’s ad and privacy controls where applicable.
---
We may update this Privacy Policy from time to time. We will post the updated version by updating the “Last updated” date and, where appropriate, provide additional notice in the App or on our website.
---
The App may let you share content using **your device’s share sheet** (for example, to another app you choose). We do not control what those other apps do with shared content.
---
This document is the **Privacy Policy** only. It explains what information we collect and how we use it.
Your use of the App is also governed by our **Terms of Use** (End User License Agreement), including rules for using the App, subscriptions and billing (where applicable), disclaimers, and limitations of liability. The full Terms of Use are published separately here:
