Privacy
Cüzhane keeps the least data it can and still work. No advertising, no tracking, nothing sold.
What we store
Using the app requires an account. What we hold is limited to:
- Your account: email address, name, and a profile photo if you upload one.
- Your groups: the names of groups you create or join, their intention text, your membership and your seat within the group.
- Your reading progress: which bab you read in which round, any babs you claimed from the pool, in a group’s cüz or Hizb portion the page you stopped on and how many pages you have read, and how many times you have read the counted passages of the Hizbü’l-Hakaik (Sekine, Delâil, istighfar) in each round.
- Your settings: interface language, theme, the times of your daily reminders (one for the Cevşen, one for the Hizbü’l-Hakaik), your notification preferences, and the reader’s typeface and size; also which tips you have already seen.
- Your notification inbox: a record of what happened in your groups — the kind of event, the group’s name, and the display name of the member it concerns.
- A device key for notifications (a push token).
- If you send feedback from the app: your message, its topic, your account email, your device’s platform, version and language, and — so we can trace a bug — the last 30 or fewer screens you opened in the app (screen names and numbers such as a bab’s; no names or text).
What we do not store
There is no analytics tool. No advertising network, no tracking pixel, no third-party cookie. We do not read your location, contacts, calendar, or anything else on your device. The text you read ships inside the app; which words you read, and when, never reaches the server — except when reading together; see below.
The Quran text
The Quran text in the app is the Madinah Mushaf of the King Fahd Glorious Qur’an Printing Complex (Madinah). It comes from the Quran Foundation’s API (quran.com) and ships inside the app. It is read on your device. When you long-press a verse, its translation is requested from the Quran Foundation at that moment, through our own server: only the verse number and the language are sent — nothing about you or your account. The translation is not stored on your device.
Who can see your data
Members of a group can see each other’s name, share and progress — that is what running a hatim together means. A group’s creator can hide names; then only the creator sees them, and in a Hizbü’l-Hakaik group so do up to three responsible members the creator chooses. Beyond that, your data is processed only by these providers:
- Clerk — accounts and sessions.
- DigitalOcean — where the server and database are hosted (Europe).
- Expo — for delivering notifications only; the notification text and the device key are passed to it.
- Cloudflare — only when the reader turns on their voice while reading together; the voice passes live through Cloudflare to reach the people following, and is not recorded.
Reading together
When you read together in the free Cevşen or Mushaf, the reader’s place — which bab or page they are on, how far down it, and the line they tap — goes through our server to the people following, live. That place is not saved: the server holds it in memory only while the session runs.
While a session runs, the server keeps a small record of it: the join code, who started it and what is being read (Cevşen or Quran). The record is normally deleted when the session ends — when the reader ends it, when the reader does not come back within a minute, after ten minutes without reading, or after four hours at most. If a session is cut off (for example by a server restart), the record can stay longer; it is deleted when that reader starts a new session, when someone looks up its code, or when the account is deleted.
Everyone in a session sees the names of the reader and of the others following; there is no group here, so names cannot be hidden. You decide who you share the code with. Reading together marks nothing as read and changes nobody’s progress.
The reader can choose to turn on their voice; it then goes live to the people in the session who choose to listen. The voice does not pass through our server: Cloudflare’s servers carry it to the people following. It is not recorded or stored, by us or by Cloudflare. The microphone is used only when the reader turns their voice on, and only while it stays on; the phone asks for permission the first time.
Notifications
The daily reminders (one for the Cevşen, one for the Hizbü’l-Hakaik) are scheduled on your device and never leave it. Separately, the server sends a notification in six cases: when a bab you claimed from the pool passes to somebody else, when someone in your group finishes their share, when your group completes a round, when someone takes babs from the shared pool, when someone joins one of your groups, and when someone leaves one. All but the first can each be turned off from the notification settings. One exception: in a Hizbü’l-Hakaik group with responsible members, only they get the “has read” notification, whatever their own settings; the other members don’t.
Deleting your data
Profile → Delete account, inside the app, permanently deletes your account and your data: groups you own along with their members, your memberships in groups you joined, your settings, your notification inbox, your device keys, and any feedback you sent. This cannot be undone.
In a group you joined but did not create, the record that a bab was read in a given round stays in that group’s history — without it, rounds the other members finished together would develop holes. That record carries an account identifier and nothing else, and once your account is gone it no longer resolves to a person.
Encrypted backups of the database are kept for 14 days on the server and at most 90 days off-site, so a deleted record persists in those snapshots for up to that long. The account deletion page has the detail.
