Your prayer data is intimate. It says when you wake up, where you live, what your daily rhythm looks like, which prayers you struggle with. It's the kind of data that, in the wrong hands, can be used to profile a community.
So which Muslim apps actually treat that responsibility seriously? After the well-documented 2020 reporting on Muslim Pro's data-sharing with X-Mode Social, this question stopped being academic.
We spent a week auditing the privacy posture of eight popular Muslim apps in 2026, what they collect, whether an account is required, what third-party trackers are embedded, and any public privacy incidents. The findings are below.
A note on this article. Privacy policies change. We checked each app's policy in March 2026 and confirmed app-side behavior with Apple's App Privacy Report and Google's Data Safety section. Always re-read the current policy of any app before relying on it. We've linked sources where we can.
Why prayer-app privacy matters
Most app-privacy discussions focus on hypotheticals. With Muslim apps the harm is documented: data brokers like X-Mode collected location data from Muslim-targeted apps and sold to military and law-enforcement entities. That data, aggregated at scale, lets buyers identify mosques, plot communities, and target individuals, not abstract risks, real ones.
This is why the bar for prayer-app privacy is higher than for, say, a weather app. The data is identifying, the user base is targetable, and the historical record shows the harm is real.
The 2020 Muslim Pro scandal, briefly
In November 2020, Vice's Motherboard reported that Muslim Pro had been sharing user location data with X-Mode Social, a data broker that sold to U.S. military contractors. Muslim Pro publicly responded the same week, cutting ties with X-Mode and saying it had not been aware of the downstream sale.
Muslim Pro has updated its privacy policy since. The reasonable question is whether you trust the policy now. That's a personal call. We mention the history because it's the single most-asked question in our support inbox and it materially shaped how the rest of the Muslim app space thinks about data.
What we checked for each app
For each of eight apps, we recorded:
- Account required? Email collection is a meaningful step in the privacy chain.
- Location collected and where it goes. Does the app process location locally or transmit it?
- Third-party SDKs. Analytics, ads, crash reporting, what's bundled.
- Apple Privacy Report disclosures. Data linked to identity vs not.
- Public privacy incidents. Any reported scandals, regulator actions, or leaks.
- Ability to use offline. Less network = fewer data leaks.
The audit, app by app
FivePrayer: strictest privacy posture in the category
- Account required? No.
- Location: Processed on-device. We never transmit or store your coordinates server-side. Times are computed locally.
- Third-party SDKs: Minimal, analytics only at the aggregate, opt-out-able level. No ad SDKs. No data brokers.
- Apple Privacy: "Data Not Collected" for personal identifiers. The optional crash log is anonymized.
- Public incidents: None.
- Offline: Yes, 30 days of times precomputed on-device.
We designed FivePrayer to be the app you'd build if the lesson from 2020 was internalized. No accounts means no email database. On-device tracking means there's no server-side log of your prayer life. No third-party trackers means there's no place for data to leak even if we wanted to leak it.
Quran.com: also excellent on privacy
- Account required? No (basic reading); optional for sync.
- Location: Not requested.
- Third-party SDKs: Minimal, primarily analytics.
- Apple Privacy: Limited data linked to identity, mostly opt-in.
- Public incidents: None.
- Offline: Most features work offline after download.
Quran.com is funded by donations and operates as a public good. Their incentives don't push them toward data monetization. The privacy posture reflects that.
Tarteel: account required but transparent
- Account required? Yes.
- Location: Not the primary use; minimal usage.
- Third-party SDKs: Analytics and infrastructure (auth, payments).
- Audio handling: Recitation inference is on-device. Uploads for model improvement are opt-in and clearly disclosed.
- Public incidents: None.
Tarteel is a serious team with a clear policy. The microphone is on-device; uploads are opt-in. Account-required is the main asterisk for privacy purists, but they've earned the benefit of the doubt.
Muslim Pro: improved but historical concerns
- Account required? Encouraged, not strictly required for all features.
- Location: Collected for prayer times; current policy says it's not shared with data brokers.
- Third-party SDKs: Ad SDKs in the free tier (this is how the ads run).
- Apple Privacy: Data linked to user identity for advertising in the free tier.
- Public incidents: 2020 X-Mode reporting.
- Offline: Partial.
Muslim Pro has done meaningful work on its privacy policy since 2020. Whether you re-trust the brand is personal. The ad SDKs in the free tier are the practical concern, ad networks have their own data flows that any privacy-conscious user has to weigh.
Just Pray: account required, growing app
- Account required? Yes.
- Location: Collected for prayer times.
- Third-party SDKs: Analytics, infrastructure, payment.
- Public incidents: None.
Just Pray is a well-funded modern app with a normal SaaS privacy footprint. The account requirement and gamification mean a heavier data footprint than FivePrayer or Quran.com, but they've been transparent and have no incident history.
Deen Buddy: adequate, normal posture
- Account required? Encouraged.
- Location: Collected for prayer times.
- Third-party SDKs: Analytics, payment, some ad activity in free tier.
- Public incidents: None reported.
Athan Pro: mature, normal posture
- Account required? No.
- Location: Collected for prayer times.
- Third-party SDKs: Ad SDKs in free tier; standard analytics.
- Public incidents: None reported.
Pillars: clean, account encouraged
- Account required? Encouraged for sync.
- Location: Collected for prayer times.
- Third-party SDKs: Analytics, payment infrastructure.
- Public incidents: None reported.
Rules for privacy-conscious Muslims
1. Prefer apps that don't require an account
An email is a key. Without it, the app can't link your prayer history to a person. FivePrayer, Quran.com, and Athan Pro can all be used fully without an account.
2. Prefer apps where location stays on-device
Prayer times can be computed entirely from coordinates and a date. There's no need for the coordinates to leave your phone. FivePrayer makes this explicit; some others fetch times server-side, which means transmitting your coordinates.
3. Be wary of free-tier ad SDKs
Ad networks have their own data pipelines. A "free" app supported by ads is, at best, a vehicle for whatever the ad network does with its data. If you can pay $3–5/month to remove ads, that's often the better privacy outcome.
4. Read the App Store privacy nutrition label
On iOS, scroll down on the App Store listing to "App Privacy." On Google Play, look at the "Data safety" section. Both are summaries the developer must keep accurate, they're a good first filter.
5. Prefer apps that let you delete your data
If an app requires an account, it must offer account deletion. Verify the option exists before you sign up. Both Apple and Google now require this for apps in their stores.

Frequently asked questions
What is the most private Muslim app?
FivePrayer for prayer; Quran.com for Quran. Both work without accounts, both keep data on-device, both have zero history of privacy incidents.
Did Muslim Pro really sell user data?
In 2020, Vice's Motherboard reported that Muslim Pro had shared user location data with X-Mode Social, which sold to U.S. military contractors. Muslim Pro publicly cut ties and updated its policy. The historical fact is documented; the current policy is improved.
Can I use a Muslim app without making an account?
Yes. FivePrayer, Quran.com, and Athan Pro can all be used fully without an account. Tarteel and Just Pray require accounts. Others encourage accounts but don't strictly require them for all features.
Is it safe to share my location with a prayer app?
It's necessary for accurate prayer times. The question is what the app does with the location after computing the times. Apps that process location locally (like FivePrayer) and don't transmit it are the safest. Apps that fetch prayer times from a server inevitably transmit coordinates.
Should I uninstall Muslim Pro?
If you're comfortable with the current Muslim Pro policy and you use Premium (ad-free), it's a defensible choice. If privacy is your top concern, switch to FivePrayer + Quran.com. We have a dedicated Muslim Pro alternative page if you want the side-by-side migration guide.
FivePrayer: the prayer app that can't see your prayer data.
All tracking lives on your device. We can't sell what we don't have. Free on iOS, Android, and Chrome.
