Qamous — Privacy Policy

Last updated: 2026-10-28

Qamous is an Arabic and Qur'an learning app. This page says what the app does with your data, what leaves your phone, and when.

No account, no server of ours

You don't sign up or log in, and there is no server run by the developer that stores anything about you. The app runs on your phone.

Your progress stays on your device

Words you know, your review history, streaks, prayer log, notebook, bookmarks, search history, settings and the languages you told the app you speak all live in the app's local storage on your phone. They are not sent to the developer or to anyone else. If you use Android's backup, Android may copy the app's data to your own Google account as it does for other apps; that is your device's setting. The saved AI key is left out of that backup. Uninstall the app or clear its data and everything is gone.

What Qamous doesn't do

No ads and no ad tracking.
No analytics and no usage tracking.
Nothing is sold or shared.
No access to your contacts or camera.

Location, microphone and sensors

Location. Only when you ask the Prayer tab to find where you are. The position is matched on the phone against a list of cities built into the app, kept on the phone (rounded) to work out prayer times and the direction of the qibla, and never sent anywhere. You can choose a city by hand instead and never allow location.
Microphone. Only while you press record in the speaking practice or the conversation. A recording stays on the device unless you use the AI feature that listens to it (see the table below).
Compass and motion sensors. Read on the phone to point the qibla arrow. Nothing is stored or sent.

What does use the network, and when

The lessons, the Qur'an text, the poetry and the English side of the dictionary are inside the app and work without a connection. These parts reach out, only when you use them or, for the update check, at most once a day:

Feature	What is contacted	What is sent
Qur'an recitation audio	everyayah.com	The request for the recording of one āyah. Recordings you download are kept on the device.
Tafsir (commentary), and the Arabic text of the large classical dictionaries and the reasons-of-revelation entries	cdn.jsdelivr.net, which serves files from public repositories on GitHub	The request for one file, such as one sūrah of one commentary or one chapter of a dictionary. It is kept on the device after the first time. As with any request on the internet, the server sees the phone's IP address.
Check for a newer version (Android app only)	cdn.jsdelivr.net, one small public file, `latest.json`, in the same repository	The request for that file, at most once a day. It carries no account, no device identifier and no version number; the app compares the number in the file with its own on the phone. If a newer version is on Google Play, a notice offers to open its Play Store page.
Watch: video clips, importing a YouTube video	YouTube (Google)	YouTube's own player loads, and YouTube sees what any site that embeds its player sees.
The optional AI features (conversation, correcting your writing, listening to your recording)	Google (Gemini) or Anthropic (Claude), whichever key you paste into Settings	The text you wrote or the recording you made, with a short instruction, sent from your phone to that provider under its own terms. Nothing is sent unless you paste a key and use the feature.

Your own AI key

If you give the app a Gemini or Claude key, it is used only to make those requests from your phone. In the Android app the key is kept encrypted under a key held in the Android Keystore, and it is left out of backups. It is never sent to the developer. You can show it, replace it or remove it in Settings at any time.

Permissions

INTERNET: for the features in the table above.
ACCESS_COARSE_LOCATION, ACCESS_FINE_LOCATION: only to find your place for prayer times and the qibla, as described above. Asked for when you use that feature.
RECORD_AUDIO, MODIFY_AUDIO_SETTINGS: only when you press record in the speaking practice or the conversation. A recording stays on the device unless you use the AI feature that listens to it, which sends that recording to the provider whose key you gave.
POST_NOTIFICATIONS: prayer reminders at the top of the screen, the adhan, and the controls shown while recitation plays.
SCHEDULE_EXACT_ALARM, RECEIVE_BOOT_COMPLETED: so a prayer reminder or the adhan comes at the minute you set, and is set again after the phone restarts. Prayer times are worked out on the phone.
FOREGROUND_SERVICE, FOREGROUND_SERVICE_MEDIA_PLAYBACK: so recitation keeps playing with the screen off.
REQUEST_IGNORE_BATTERY_OPTIMIZATIONS: only to show the system dialog, because some phones stop playback and reminders in the background.

Reporting a problem

"Report a problem" opens your own mail app with the message written, and any screenshots you added attached, addressed to the developer. You see everything and press send yourself; the app sends nothing on its own.

Changes to this policy

If anything here changes, this page is updated and the date at the top moves.
