Privacy Policy

1. Who we are

Zeen – Prayer Times & Quran provides accurate Islamic prayer times, Qibla direction, Quran reading, dhikr tracking, live Quran radio and related religious utilities through our mobile apps and web services.

The data controller responsible for your personal data in connection with the services is:

Faruk Selim Yıldız
Istanbul, Türkiye
Email: support@zeenprayertimes.com

2. Scope of this Policy

This Privacy Policy explains how we collect, use, store and share information when you:

• Visit or use zeenprayertimes.com and its subpages.
• Use the Zeen mobile applications on iOS or Android.
• Access our APIs or widgets integrated into other services.

By using our services, you agree to the collection and use of information in accordance with this Policy.

3. Information we collect

We collect only what each feature genuinely needs to work, or what we need to keep the app fast, stable and reliable — because a prayer times app that is slow, crashes, or fires a late adhan notification has failed at its one job. Every data point below exists to serve one of those two goals, and we explain the specific reason next to each one.

3.1 Information you provide directly

As of the date shown above, Zeen does not offer user accounts or sign-in. Many core features work on your device without you needing to create an account or provide personal details such as your name or email.

You may still choose to provide information to us in the following situations:

• Complaint and suggestion form: if you submit a complaint, suggestion or feedback through the in‑app feedback form, we process the information you enter — typically the name you choose to provide, the selected topic and the content of your message. The in‑app form does not require an email address. Your submission is sent together with your pseudonymous device identifier and the app version, so that we can respond to you through the app's support inbox and diagnose the issue. If you additionally contact us by email, we also process your email address (see below).
• Direct contact: if you contact us by email, we process your email address and any other information you include in your message.
• Donations and supporter details: Zeen includes an optional “Support the developer” feature (a voluntary tip jar). It does not unlock any functionality. If you choose to donate, you may optionally provide a display name and a short message, or donate anonymously. Unless you choose to donate anonymously, the display name and message you enter are shown publicly to other users in the app on the “Recent supporters” list and the supporters wall. Do not include sensitive personal information in these fields. See Section 3.2 for the technical details we record for each donation, and Section 6 for the payment providers involved.

If we introduce user accounts in the future, we will update this Policy before or at the time those features become available.

3.2 Information we collect automatically

We do not use third‑party analytics SDKs or advertising trackers in Zeen. Everything described in this section is first‑party data, collected by the app itself and sent to our own servers (operated under the zeenprayertimes.com domain). It is linked only to a pseudonymous device identifier and is not associated with your name or email.

• Device and technical information: a pseudonymous device identifier, device model, operating system and version, app version, battery status, network connection type (for example Wi‑Fi or cellular), and your device region and language derived from your system settings. We need this to reproduce a problem that only shows up on a specific device model or OS version, and to know which platforms to prioritize when fixing bugs.
• App settings: your in‑app preferences, such as interface language and theme, the prayer‑time calculation method you use, whether automatic location is enabled, and whether notifications are enabled.
• Usage data: how you interact with the app, such as which screen you are currently viewing, session identifiers, and the amount of time spent in the app. We use this to see which features are actually used before investing engineering time in them, and to measure performance and stability per screen.
• Performance and reliability data: app launch time; frame‑rendering smoothness (the share of frames that miss their rendering budget, and typical frame duration); memory (RAM) usage, including peak usage during a session; device thermal state; available storage and app cache size; and, when the app terminates unexpectedly, the reason reported by the operating system's own diagnostics (for example a crash, an unresponsive‑app timeout, or the system freeing memory under pressure). We collect this because it is the only way to catch a regression — such as a new version that runs out of memory on older phones, overheats the device during Quran audio playback, or freezes during Fajr right when you need it — before it reaches most users, rather than after enough people leave one‑star reviews.
• Network and radio performance data: latency and success/failure rate of requests the app makes to our servers, the amount of data transferred, and — if you use the live Quran radio feature — playback interruption counts and average buffering time. This lets us tell a genuine server or CDN problem apart from a single user's poor connection, and fix the one we're actually responsible for.
• Notification delivery accuracy: the difference between the time a prayer‑time notification was scheduled to fire and the time it actually fired, and whether background refresh tasks completed successfully. A late or missed adhan notification defeats the core purpose of this app, and some device manufacturers' battery‑optimization behavior can silently break background notifications without our knowledge. This metric is how we detect that on a given OS version or device brand and work around it.
• In‑app activity data: summary information about your use of the app's religious features, including prayer tracking (which daily prayers you mark as completed and your streaks), Quran reading progress (such as your current surah/verse, completion percentage, reading streaks and experience points) and dhikr/tasbih counts and targets. We only collect this in the aggregate form needed to see whether these features are actually helping people build a consistent practice (for example, the share of users who keep a 30‑day streak) so we can improve them — not to build a profile of any individual's religious observance. Because this reflects religious belief and practice, we process it only with your consent; see Section 5 for the legal basis and how to withdraw it.
• Donation records: if you make a voluntary donation, we record details of that donation on our servers, linked to your pseudonymous device identifier. This includes the support tier and product identifier, the quantity, the amount and currency, the store transaction identifier, whether the donation was marked anonymous, and the optional display name and message you entered. As noted in Section 3.1, unless you donate anonymously, your display name and message are shown publicly to other users inside the app. Payment itself is processed by the app stores; we do not receive your card or bank details (see Sections 4 and 6).
• Website logs: when you visit zeenprayertimes.com, standard server logs may record technical information such as your IP address, browser type, timestamps and the pages you visit. These logs are used only for security, error diagnosis and basic operational purposes.

You can limit some of this collection through your device settings (for example, by disabling location access or notifications). Because this data is tied only to a pseudonymous identifier and not to your name or account, we may be unable to link it back to you individually to action a specific request (see Section 9).

3.3 Location information

Accurate prayer times and Qibla direction require location-related information. Depending on your settings, Zeen may process:

• Precise location from your device’s GPS or similar technologies, only if you grant permission in your device settings.
• Manually selected location, such as city or coordinates that you choose within the app.

Location data is used to calculate prayer times and Qibla direction on your device. When automatic location is enabled, the app may also send a coarse location label — such as your district or the city name you selected — to our servers as part of the diagnostic data described in Section 3.2, so we can understand the regions where Zeen is used and prioritize regional accuracy and language support accordingly. We do not send your precise GPS coordinates to our servers. If you prefer not to share precise location, you can manually select your city or coordinates and still use the core features.

4. How we use your information

We use the limited information we collect for the following purposes:

• To calculate and display accurate prayer times and Qibla direction for your chosen location.
• To provide core features such as Quran reading, live Quran radio, dhikr tracking, reminders, widgets and notifications.
• To store and apply your preferences (language, theme, juristic method, notification settings, etc.) on your device.
• To keep the app fast and stable release over release — measuring launch time, frame smoothness, memory use, crash and freeze causes, network reliability and notification timing accuracy so we can catch and fix regressions before they affect most users.
• To understand, in aggregate, how features such as prayer tracking, Quran reading and dhikr counting are used, so we can improve them, using the in‑app activity data described in Section 3.2 and processed on the basis of your consent (Section 5).
• To respond to your inquiries, complaints, suggestions and other support requests.
• To process voluntary donations, record and display supporter information (including the public “Recent supporters” list, unless you donate anonymously), and recognise your device as a supporter within the app.
• To maintain the basic security and technical operation of the website (for example, through server logs).
• To comply with legal obligations and enforce our legal rights where necessary.

Zeen currently offers voluntary in‑app donations only; it does not sell paid premium features or subscriptions. Donation payments are processed by the relevant app stores (Apple App Store or Google Play) together with our purchase infrastructure provider (see Section 6). We do not receive your full payment card or bank account details. If we later introduce paid premium features or subscriptions, we will update this Policy with more detail before those features go live.

5. Legal bases for processing (for EEA/UK users)

If you are located in the European Economic Area or the United Kingdom, we process your personal data based on one or more of the following legal bases:

• Performance of a contract: providing the services you install and use, including prayer time calculations, notifications and Quran-related features.
• Legitimate interests: maintaining the security, performance and stability of our services (Section 3.2's device, performance, network and notification‑accuracy data), preventing misuse, and responding to your messages, where these interests are not overridden by your rights.
• Consent: our religious‑practice features — prayer tracking, Quran reading progress, and dhikr/tasbih counting — reveal information about your religious belief and observance, which is a special category of data under Article 9 GDPR (and “özel nitelikli kişisel veri” under KVKK Article 6). We process the in‑app activity data generated by these features only with your explicit consent, obtained separately from general app functionality. You do not need to consent to use these features on your device — consent only governs whether summary usage data about them is sent to our servers. You may withdraw consent at any time via the relevant in‑app privacy control, where available, or by contacting us at support@zeenprayertimes.com; withdrawal stops future collection but, because this data is tied only to a pseudonymous device identifier, we may be unable to identify and remove specific past entries (see Section 9). We also rely on consent for precise location, which you grant or withdraw through your device settings.
• Legal obligations: where processing is necessary for compliance with applicable law.

6. How we share your information

We do not sell your personal data and we avoid unnecessary sharing. We may share information in the following situations:

• Service providers for our app, website and email: we may use hosting and infrastructure providers for zeenprayertimes.com and our backend services, and email services to handle messages sent to support@zeenprayertimes.com. These providers are allowed to use your data only as necessary to provide their services to us and are bound by confidentiality and data protection obligations.
• Payment and donation processing: when you make a donation, the payment is handled by the relevant app store (Apple App Store or Google Play), and we use RevenueCat as our purchase infrastructure provider to validate the transaction and relay the donation details you entered to our servers. These parties process the data only to complete and record the purchase. We do not receive your full payment card or bank account details.
• Other users of the app (supporters wall): if you make a non‑anonymous donation, the display name and message you choose to provide are shown publicly to other Zeen users within the app. This is not a sale of data; it happens only with the information you deliberately enter for that purpose.
• Legal and safety reasons: when required to do so by law, regulation, legal process or governmental request, or when we believe in good faith that disclosure is reasonably necessary to protect our rights, users, or the public.
• Business transfers: in connection with a merger, acquisition, reorganization or sale of all or part of our assets, where the receiving party will be bound by privacy commitments consistent with this Policy.

We do not use third‑party advertising networks, remarketing services or cross‑app tracking SDKs in Zeen.

7. Cookies and tracking technologies

Our website zeenprayertimes.com may use strictly necessary cookies or similar technologies to:

• Remember basic preferences (such as language or dark/light theme).
• Maintain session security and protect against abuse.

We do not use third‑party advertising cookies or third‑party analytics cookies on the website. You can control cookies through your browser settings. Disabling some cookies may affect certain functions of the website.

8. Data retention

We keep your personal data only for as long as necessary for the purposes described in this Policy, unless a longer retention period is required or permitted by law.

• App configuration and preferences are stored locally on your device (for example, in local storage such as AsyncStorage) and remain there until you delete the app, clear app data or change settings.
• Diagnostic, performance, network, notification‑accuracy, usage and in‑app activity data sent to our servers (Section 3.2) is retained for a limited period for troubleshooting, reliability monitoring and product‑improvement purposes, after which it is deleted or aggregated.
• Emails and complaint/suggestion submissions are kept as long as necessary to handle your request and maintain proper records.
• Server logs for the website are retained for limited periods to ensure security and correct technical operation.

9. Your rights

Depending on your location and applicable law, you may have some or all of the following rights regarding your personal data:

• Right to access the personal data we hold about you.
• Right to request correction of inaccurate or incomplete data.
• Right to request deletion of your data in certain circumstances.
• Right to object to or restrict specific types of processing.
• Right to withdraw consent where processing is based on consent, including the religious‑practice data described in Section 5.
• Right to data portability, where technically feasible.

To exercise these rights, contact us at support@zeenprayertimes.com. We may ask you for information to verify your identity before we respond. Please note that the diagnostic, performance and usage data described in Section 3.2 is tied only to a pseudonymous device identifier; if you contact us, you may need to provide that identifier so that we can locate the relevant records.

If you are in the EEA or UK, you also have the right to lodge a complaint with your local data protection authority.

10. Children’s privacy

Zeen is intended for a general audience and is not specifically directed to children under the age of 9. We do not knowingly collect personal data from children under 9 years old. If you believe a child under 9 has provided us with personal data, please contact us so that we can delete it.

11. Data security

We use reasonable technical and organizational measures to protect your information from unauthorized access, loss, misuse or alteration. However, no method of transmission over the internet or method of electronic storage is completely secure, and we cannot guarantee absolute security.

12. Third-party links and integrations

Our app and website may contain links to third-party websites, services or content (for example, external articles or app store pages). We are not responsible for the privacy practices or content of those third parties. We encourage you to review their privacy policies before providing them with personal data.

13. Changes to this Policy

We may update this Privacy Policy from time to time. When we make material changes, we will update the “Last updated” date at the top of this page and, where appropriate, provide additional notice (for example, inside the app or on the website).

Your continued use of Zeen after the updated Policy becomes effective means that you accept the changes.
