Effective date: 25 July 2026 · Name updated 17 August 2026 (formerly “Qalb Salim”) · “Your masjid” section added 22 August 2026 · masjid search described 23 August 2026 · purchases section simplified 6 September 2026 (RevenueCat removed from the app) · 12 September 2026: “Leaving it for Allah” section added; disclosure — Android closed-test builds from 23 August to 12 September 2026 included an on-device text-matching library that could send anonymous usage statistics (app version, feature name, timing — never your words, worship data or identity) to its vendor, Google; it was removed the day we found it, and the library is being replaced
The short version: your heart's data belongs to you. We built Qalbun Saleem so that we never see it.
Nothing. Qalbun Saleem has no accounts, no analytics, no advertising, no tracking SDKs, and no server of ours. We do not collect, receive, transmit, sell, or share your personal data. We cannot see your check-ins, your notes, what you type, your worship logs, or your location. The app does not use the internet at all unless you connect it to your masjid (see below).
Everything you record in Qalbun Saleem — heart check-ins, notes, dhikr counts, prayer and fasting logs — is stored locally on your device.
If you turn on iCloud sync (it is off by default), your data is stored in your private iCloud database under your own Apple ID, so your devices can stay in sync. That data moves between your device and Apple's iCloud — never through us. We have no access to it. Apple's handling of iCloud data is governed by Apple's Privacy Policy.
When you describe what's weighing on you, the matching to suggested adhkar happens entirely on your device. Your words are never sent anywhere — not to us, not to any AI service, not to any third party.
You can connect the app to your local masjid so it shows the masjid's own adhan and iqamah times and announcements. This is off until you connect one. When you do, the app fetches that masjid's public timetable from the service the masjid publishes on (for example Masjidal, Mawaqit, or a feed address you enter), directly from your device, about four times a day. This is the only time the app uses the internet. The request carries nothing about you — no account, no identifier, no location, no logs — only the masjid's public ID. Those services may see your device's IP address, as any website you visit does; their own policies apply to their servers. Disconnecting the masjid stops all network use.
Finding your masjid. To make connecting easy, the app can search Mawaqit's public masjid directory. A search sends only the words you type in the search box to Mawaqit; if you tap “Masjids near me”, it sends your approximate coordinates (rounded) instead, once, to return nearby masjids. Nothing else is sent, nothing is stored by us, and no search happens unless you type or tap. Mawaqit's own policies apply to their servers.
If you use the app's private track for leaving a habit, everything you record there — the habit you chose, your triggers and fences, your held days and renewals — is kept in a separate store that is device-only: it is not backed up to iCloud or Google, never synced, never part of the app's export file, and never read by any other part of the app. One tap erases it completely. The only way it leaves your phone is if you yourself choose to share a summary — by default counts only, with no names — with someone you trust.
If you grant location access, it is used once, on your device, to calculate prayer times — and it is not transmitted for that. The only time a position ever leaves your phone is when you yourself tap “Masjids near me” (rounded, once, to Mawaqit — see above). You can instead enter coordinates manually — location permission is optional.
Qalbun Saleem is free. Neither the iOS app nor the Android app contains purchases, subscriptions, or any purchase-processing code. If paid features are ever introduced, this policy will be updated here first, before any purchase infrastructure ships.
Qalbun Saleem does not knowingly collect data from anyone, including children, because it does not collect data at all.
Qalbun Saleem offers spiritual companionship, not medical or psychological treatment, and does not diagnose or treat any condition. If you are struggling, please reach out to a qualified professional or a crisis line.
If this policy ever changes, the new version will be posted at this address with a new effective date. Since the app's entire design is "collect nothing," meaningful changes are unlikely.
