Wasilah · Data Deletion
Request data deletion
Wasilah is privacy-first: we do not require an account, and we collect only the minimum data needed to deliver prayer times, Quran audio, Qibla direction, and notifications. This page explains exactly how to delete any data we hold about you.
The simplest method. Uninstalling Wasilah from your device:
- Deletes all locally-stored data (preferences, downloaded audio, bookmarks, cached prayer times)
- Invalidates your Firebase Cloud Messaging push token, so we can no longer notify your device
- Stops new analytics and crash data from being sent
For the residual data that remains on Google's Firebase servers (crash reports, anonymous analytics events), follow the steps below.
What we hold and where it lives
| Data type | Where it is stored | Default retention |
|---|---|---|
| App preferences, bookmarks, cached audio | Locally on your device only | Until uninstall |
| Crash reports | Google Firebase Crashlytics | 90 days |
| Anonymous analytics events (screen views, sessions, app version) | Google Firebase Analytics | Up to 14 months |
| Push notification token (FCM) | Google Firebase Cloud Messaging | Until you uninstall the app or revoke notification permission |
| Location coordinates | Sent to AlAdhan API to compute prayer times. Not stored by us. | Not retained |
We do not hold names, email addresses, phone numbers, contacts, photos, payment information, or any account credentials.
How to request deletion — step by step
Step 1 — Uninstall the app
Long-press the Wasilah icon on your home screen and choose Uninstall (Android) or Remove App → Delete App (iOS). This deletes all on-device data and invalidates your push token.
Step 2 — Email us to delete server-side data
To request deletion of crash reports and analytics data held by Google Firebase, email us at:
privacy@wasilah.site
Include in your email:
- The subject line "Data deletion request"
- The approximate date you last used the app
- Your device model and operating system version (helps us identify the relevant records)
- (Optional) Your Firebase Installation ID, if you have it. The app does not show this to you, so leave blank if not applicable.
We will action your request within 30 days and confirm by email when the deletion is complete.
Step 3 — Verification
Because Wasilah does not collect names, emails, or other identifiers, server-side records are pseudonymous. To confirm we have deleted your records, we will reply to the email address you wrote from with a confirmation note and a description of what was deleted.
What gets deleted, and what is kept
Deleted on request:
- Crash reports tied to your installation in Firebase Crashlytics
- Analytics events tied to your installation in Firebase Analytics
- FCM push tokens associated with your installation
Retained (anonymised, with no link to you):
- Aggregate analytics summaries — for example, "1,200 users opened the Quran reader this week". These contain no identifier that points back to your device.
- Server logs from third-party services (Google Firebase, IslamicNetwork's AlAdhan API, IslamicNetwork's audio CDN) which are governed by those providers' own retention policies.
Direct deletion via Google
For data held by Google Firebase, you may also contact Google directly to exercise your rights. See Google's Privacy Policy and the privacy controls available through your Google account.
