I posted recently about Facet, an Android gallery app I’m building that tries to solve a specific privacy problem:

Sometimes you want to hand someone your phone without turning your whole photo library into a liability.

Facet is not a photo vault. It does not ask you to manually hide/import photos. It works more like a normal gallery, but uses on-device analysis to decide what should be visible in a normal “handoff” context.

The feedback so far has been really useful. The main concerns people raised were exactly the ones I’ve been designing around:

False positives: harmless photos being hidden
False negatives: sensitive photos being shown
Trust: whether the analysis leaves the device
Control: whether the user can override mistakes

Current approach:

Analysis is on-device
No cloud photo upload
The app is read-only against your photo library
Sensitive/uncertain items are treated conservatively
Feedback can be shared from inside the app to improve the rules

The Android closed test is now easier to join:

Join the test here:
https://play.google.com/apps/testing/io.facetapp.facet
Then download here:
https://play.google.com/store/apps/details?id=io.facetapp.facet&pli=1

I’m especially interested in feedback on whether the default filtering feels too strict, too relaxed, or about right.

Hi everyone,
I’m looking for Android testers for Facet, a privacy-focused photo gallery app I’ve been building.
The idea is simple: instead of manually hiding photos in a vault, Facet acts more like a normal gallery that adapts what it shows depending on context. It keeps everything on-device, with no cloud photo upload and no analytics.
I’m currently preparing for a quiet Android release and need more testers to help validate the app across different devices, photo libraries, and real-world usage.
I’m especially looking for feedback on:
Whether the gallery feels natural to use
Whether the adaptive filtering makes sense
Any obvious false positives/false negatives
Performance on different Android devices
Anything confusing, broken, or missing

You can join the official closed testing track at facetapp[.]io and download from Google Play here: https://play.google.com/apps/testing/com.facet.app

It’s early, but the core app is working. Any testers or feedback would be hugely appreciated.

I’m looking for a few Android testers for Facet, a private on-device gallery app I’m building.

It helps make your photo gallery more context-aware, so the app can show a cleaner Adaptive Gallery while keeping analysis on your phone. No cloud upload, no account, no analytics.

Google requires 12 testers for 14 days before I can publish. You’d just need to install the closed test, keep it installed/opted in for 14 days, try the main gallery/album/viewer flows, and send me brief feedback if anything feels confusing or broken.

You’ll need an Android phone and the Gmail address you use for Google Play. Message me if you’re happy to help.
