How Hafidz handles your data

Last updated: May 22, 2026

Hafidz is built to be useful even with the network off, so by default it stores everything on your device and sends nothing back to us. This page describes exactly what that means.

What stays on your device

Which verses you have marked as memorised, and their strength (Fresh / Firm / Mutqin).
Your review history — every Again / Hard / Good / Easy rating and the timestamp.
Your reading position, daily streak, daily target, and the verses you have flagged as "stumbles".
App preferences: reciter, translation language, reader mode, active-recall mode, tasbih count.
Cached mushaf pages and tafsir text fetched for offline use.

All of this lives in a local SQLite database inside the app's sandboxed storage. It never leaves your device through any code we wrote, and there is no Hafidz account or user identifier.

What we send over the network

Hafidz fetches Quran content from publicly-available sources so the app can run without us hosting anything ourselves:

Verses, words, and translations from the Quran.com API.
Tafsir text from equran.id (Indonesian / Kemenag) and from bundled sources for other languages.
Recitation audio streamed from the reciter's public audio CDN at playback time.

These requests carry the standard network metadata your device attaches to any HTTP call (IP address, user-agent, the verse identifier being requested). We do not add any custom tracking headers, and we do not log these requests on our side.

Analytics & advertising

Hafidz contains no analytics SDK, no crash-reporting service, and no ads. We do not know how many people use the app or which features they use.

Children

Hafidz is suitable for all ages and does not collect personal information from anyone, including children under 13.

Data retention & deletion

Because all your data lives on your device, you control it completely. Deleting the app from your device removes everything: memorisation records, review history, cached content, and preferences. There is no server-side copy to request.

Third-party services

The third parties Hafidz contacts are listed above (Quran.com, equran.id, the reciter's audio CDN). Their own privacy policies apply when your device connects to them — please consult those services directly if you need detail on their practices.

Changes to this policy

We will update this page when our practices change and bump the "Last updated" date at the top. Material changes will be noted in the app's release notes as well.
