Privacy policy.
LAST UPDATED · APRIL 2026
The short version: your photos never leave your device. Purge is designed so the only data we can see is anonymous event counts — things like "a scan finished" or "the app was opened." We don't know who you are and we never see image content.
1. What stays on your device
All of the following are processed and stored only on your iPhone, inside the Purge app's sandbox. None of it is ever uploaded to us or any third party:
- Your photo library and any thumbnails Purge generates while scanning.
- The perceptual-hash and Vision feature fingerprints used to group near-duplicates.
- Clusters, day groups, and which photos you've marked, kept, or removed.
- Your streak history and settings.
Uninstalling Purge removes all of this data.
2. What we collect
Purge uses Google Firebase Analytics to collect a small, fixed set of anonymous product-usage events. We use this only to understand, in aggregate, how the app is performing and whether features work. The events are:
app_open— the app was opened.scan_completed— a library scan finished. Includes the total photo count and how many day-groups were produced.swipe_session_completed— a review session ended. Includes how many photos were kept, trashed, or favorited during the session.photos_removed— photos were moved to Recently Deleted. Includes the count and total bytes.space_saved_milestone— a cumulative storage milestone was reached. Includes total bytes saved.day_opened— a day view was opened. Includes the day's photo count and the date (e.g. "2026-04-21").push_notification_opened— a push notification was tapped. Includes the notification identifier.- Your current streak tier and length are attached to events for segmentation.
We never send image content, file names, album names, location data, contact information, or anything that identifies a specific photo. Firebase additionally collects a randomly generated install ID and standard device metadata (iOS version, device model, app version, country); see Firebase's privacy documentation for details.
3. What we do not do
- We do not upload your photos, thumbnails, or fingerprints.
- We do not require an account — there is nothing to sign up for.
- We do not sell, rent, or share your data with advertisers.
- We do not use third-party ad or attribution SDKs.
- We do not track you across other apps or websites.
4. Push notifications
If you allow notifications, Purge may send you local reminders (e.g. "your streak is about to break") scheduled on your device, and occasionally remote notifications (e.g. "your library has new photos to review") delivered via Apple's push service. You can turn these off at any time in Settings → Notifications → Purge.
5. Photo library permission
Purge requests Full Access to your photo library via Apple's PhotoKit API. This is required so the app can (a) read your photos to group near-duplicates, and (b) move items you select into iOS's Recently Deleted album. You can revoke this access at any time in Settings → Privacy → Photos → Purge.
6. Children
Purge is not directed at children under 13 and does not knowingly collect personal information from them.
7. Your rights
Because Purge is anonymous and we do not maintain accounts or personal profiles, there is no per-user data for us to export or delete. However, if you would like us to purge (pun intended) the anonymous event stream tied to your install, email lucas@scariot.fr from the device in question and we will clear it.
8. Changes to this policy
If we change how Purge handles data, we will update this page and revise the "Last updated" date at the top. Material changes will also be announced in the app's release notes.
