Privacy

Matryoshka keeps your things on your iPhone and in your own iCloud. We never see them.

Last updated November 12, 2026. This covers the Matryoshka iPhone app, made by Bundle Apps.

In short: no account, no sign-in, no ads, no analytics and no tracking. The app doesn't talk to any server of ours. The only place your data goes is your own iCloud, and only when iCloud is on.

What the app keeps

The places, items, photos, names, labels, notes and counts you add. They're stored on your iPhone.

iCloud sync

When iCloud is on for Matryoshka, your things sync through the private iCloud database of the Apple Account signed in on your iPhone. Only you can read that database. Bundle Apps can't see what's in it. Apple's privacy policy covers how iCloud stores it.

If iCloud is off or unavailable, everything stays on your iPhone only.

Photos and the camera

The camera is used only when you take a photo in the app. When you pick photos from your library, Apple's photo picker gives the app only the photos you choose.

Finding things in a photo, outlining them, reading the words on them and suggesting names and labels all happen on your iPhone, using Apple's on-device Vision and, on iPhones with Apple Intelligence, Apple's on-device language model. Photos aren't sent anywhere for this.

Search

Your places and items are added to your iPhone's own search (Spotlight), so you can find them from the Home Screen. That index stays on your iPhone.

Counts kept on your iPhone

The app counts how many suggested labels you keep, to help it suggest better ones. The count stays on your iPhone and isn't sent to us.

Beta testing with TestFlight

If you use the beta through Apple's TestFlight, Apple shares crash reports, and any feedback or screenshots you choose to send, with us. We use them only to fix and improve the app. Apple's TestFlight terms describe what TestFlight collects.

Deleting your data

Children

Matryoshka collects nothing about anyone, including children.

Changes

If what the app does with your data changes, we'll update this page and the date at the top before the change ships.
