Muisto privacy policy

Last updated October 13, 2026

Muisto is made by Alderleaf Studios Inc. It turns the photos on your iPhone into books. Our photo libraries hold thousands of memories that we rarely look at again. Muisto binds them into beautiful photo books, so you can sit down and relive them the way you once paged through a family album.

What we collect

Nothing. Muisto has no accounts, no analytics, no advertising and no tracking. Alderleaf Studios Inc. does not receive your photos, your books, your notes or anything about how you use Muisto.

Your photos

• Muisto reads your photo library with the access you give Muisto in iOS and you can change that access at any time in Settings.
• Your books, the pages you edit, the stickers and words you add, and your settings are stored on your iPhone.
• Muisto never uploads your photos anywhere.
• If your library is kept in iCloud Photos, iOS may download full-size copies of your photos from your iCloud account so Muisto can show them. That happens between your device and Apple under your iCloud settings. Muisto is not involved in downloading or uploading the photos.

Words written for your pages

Some styles write a line about a photo or name a book. Muisto does this with Apple's on-device language model, on your iPhone. The photos and the text are not sent to Alderleaf Studios Inc. or to anyone else.

Place names

To name the places your photos were taken, Muisto asks Apple Maps for the place at a photo's location. Only the location (its latitude and longitude) is sent, to Apple, and that request is covered by Apple's privacy policy. The photo itself is never sent. The place names Muisto finds are kept on your iPhone.

Purchases

Unlock All Albums is bought through the App Store. Apple handles the payment and Alderleaf Studios Inc. never sees your payment details or Apple Account. Muisto keeps a record of whether you have unlocked and which album you chose to read for free on your iPhone, in its settings and in the iOS keychain, so that a reinstall does not lose them.

Children

Muisto collects no information from anyone, including children.

Changes

If this policy changes, Muisto will update this page and the date at the top.
