What to Look For When Choosing an Ad-Free, Privacy-Respecting Prayer App
Worship apps can know which prayers you pray and when, where you are, which duas you search for and how many make-up prayers you owe. This information is not just personal; it is sensitive. When choosing an app, beyond the feature list you should also look at privacy, accuracy and reliability.
The list below can be used to evaluate any app; it was not prepared to promote a particular app.
1. Religious data is sensitive data
Article 6 of Turkey's Law No. 6698 on the Protection of Personal Data (KVKK) classes data about religion, sect or other beliefs, as well as health and sexual life, as special categories of personal data. Processing such data requires one of the exceptions, such as explicit consent, and the necessary safeguards to be in place. Which prayers you pray, your choice of school of thought or your days of excuse may fall into this category. Find out why and where the app stores this data.
2. Checking privacy and tracking
- Are there ads? Ad networks generally collect device information. An ad-free app is safer in this respect.
- Tracking and analytics: Does the privacy policy mention analytics, tracking or marketing-oriented third-party libraries?
- Is an account required? An app that does not require an account reduces the chance of data being accumulated against your identity.
- Location permission: Location is enough for prayer times; pay attention to whether the location leaves the device. Constant background location permission is generally not needed.
- Unnecessary permissions: Permissions such as contacts, microphone and camera are not normal for a prayer-times app.
- Data retention and deletion: How long your data is kept and how it can be deleted should be clearly stated.
3. Transparency
You should be able to easily find the app's publisher (data controller) and contact details, the KVKK privacy notice and the privacy policy. Clearly stated company details such as address and tax/Mersis number are one of the signs of trust. If there is a subscription or purchase, the price and cancellation terms must be clear.
4. Accuracy of prayer times
The exact minute of prayer and iftar times can have religious consequences. Decision No. 8 of the Religious Affairs High Council states that in determining prayer, imsak and iftar times, following the calendars is the basis; if one breaks the fast earlier than the Maghrib time, the fast must be made up. It is therefore important that an app clearly states which method it uses (whether it is based on Diyanet, with which angles and tamkin (safety margin) values) and whether the calculation is made for the provincial center or the district. For a time that looks off, compare it with Diyanet's official page.
5. Reliability of the adhan and reminders
Whether an adhan reminder sounds on time depends on the phone manufacturer's battery settings. A good app should show the user when the adhan might not sound and explain the necessary permission steps. For detailed solutions, see our guide on the adhan not playing. Recorded reminders are not a substitute for the adhan called in the mosque; this should be stated clearly.
6. Quran text and the source of religious content
Under Article 6 of Law No. 633 (as amended by Law No. 7549), audio, video and electronic Quran publications that do not carry the approval and seal of the Board of Mushaf Review and Recitation cannot be published. If an app contains Quran text or recitation, it is expected to state its source and approval information. For translations (meal) and hadith content, the translator and the source (book, chapter, number) must be clear; unsourced, chain-message type content is not preferable. Seeing that religious information is tied to Diyanet sources also inspires confidence.
7. Licensing and copyright
The Religious Affairs High Council states that using software, books and music without permission is not permissible. For a practicing user, it is also a sign of trust when an app clearly states which audio, translation, hadith or text sources it uses and under what license. If this information is in the app's "About" or "Sources" section, that is a positive indicator. It is also expected that you can see who recites the Quran or who translated it.
8. Paid features and family sharing
Apps that look free may earn their income from advertising or data analytics; in a paid app, the price, subscription period and way to cancel must be clear. If there is a feature for sharing with family members, check what information is shared (for example, only whether the adhan sounded) and whether your explicit consent is asked for it. Sharing of sensitive data with others should be off by default.
9. Quick checklist
| Question | Ideal answer |
|---|---|
| Are there ads? | No |
| Is there a third-party tracking library? | No, or clearly documented |
| Is an account required? | No |
| Does the location leave the device? | No, or clearly explained |

Mumin App works according to these principles: no ads, no third-party tracking software and no cookies are used; data is not sold. To improve the app, anonymous usage statistics (screen usage, version, phone type, selected city, error logs) are collected and can be turned off in settings; privacy and KVKK notice information is published openly. See the privacy page for details. As with any app, we recommend that you verify Mumin App's claims yourself.
Frequently asked questions
Why does a prayer-times app ask for location?
Prayer times are calculated from the latitude and longitude of where you are, so location is needed. Whether the location stays on the device and whether constant background location permission is requested matter for privacy.
Why is religious data special-category personal data?
Article 6 of Law No. 6698 (KVKK) classes data about religion, sect or other beliefs as special-category personal data; processing it is therefore subject to strict conditions.
Should an app's prayer times be the same as Diyanet's?
In Turkey, Diyanet publishes the official prayer times. Apps can calculate based on Diyanet's method, but for official times, Diyanet's publication should be treated as the reference.
