Your days, the way you actually shot them
Each entry holds the photo, the story, and the gear that made it — grouped by month, newest first. No feeds, no likes, just your own record.
She finds the words, whatever camera you're holding
Mira looks at your photo and writes the entry for you — the light, the framing, the mood. Works the same for Fujifilm, Nikon, or Leica, and runs entirely on-device when your hardware supports it.
The recipe, not just the result
Dynamic range, white balance shift, shadow, color chrome FX blue — Folio reads the full recipe straight from the file and turns it into a card you can save or share.
Find the shot by the gear that took it
Browse every photo in your diary as one grid, then filter by camera, lens, or recipe to see exactly how a setup performed across dozens of shots.
Your looks, organized by name
Folio quietly groups every photo by the recipe behind it — PRO Neg. Hi, Classic Chrome, ACROS+Ye — so a whole roll's worth of one look is one tap away.
See the days you picked up the camera
A quiet heat map of your shooting activity, month by month, with every photo from a given day one tap away.
When you're bright, you reach for PRO Neg. Hi
Folio doesn't just count your photos — it notices what you reach for. Your top camera, your top recipe, and the quiet correlations between how you feel and how you shoot.
The same diary, built for the bigger screen
Folio isn't a stretched iPhone app on iPad — it's a real sidebar, a wider grid, more of your diary visible at once. iPhone and iPad, designed together from day one.
Made by one person, for people who care about this stuff
Folio is built by a single developer, with no ad network, no analytics, and no tracking of any kind. If you'd like to support the work, an optional tip is always appreciated — never required.

Last updated June 2026
The short version
Folio is built by one person. Your diary entries and photos are stored on your device and in your personal iCloud account — Folio has no servers of its own and never sees your diary. The only time a photo leaves your device is when you use Mira on a device that doesn't support on-device AI, and that is always your choice.
What Folio stores
When you use Folio, the following is saved on your device and, if you're signed into iCloud, synced privately through Apple's iCloud service:
- Your diary entries — titles, written descriptions, dates, and moods
- Photos you add to entries
- Camera and gear metadata read from your photos — film simulations, picture controls, camera model, lens, and exposure settings
- Your diary name and in-app preferences
Folio reads camera metadata directly from your photo files. This data stays on your device and in your iCloud account alongside the rest of your diary.
iCloud sync
If you are signed into iCloud, your diary syncs across your devices using Apple's CloudKit and iCloud Key-Value Storage. This sync is private and governed by Apple's Privacy Policy. Folio never has access to your iCloud data.
Mira, your AI writing assistant
Mira looks at your photos and writes diary entries in your voice. How she works depends on your device:
On-device (iPhone 15 Pro or later, iOS 27+, Apple Intelligence enabled)
Mira runs entirely on your device using Apple's on-device AI. Your photos never leave your device and are not sent anywhere.
All other iOS 26+ devices, or by choice in Settings
When you tap "Write with Mira," your photo is sent to Anthropic's AI (Claude Haiku) to generate your diary entry. You will see a notice the first time this happens and can cancel at any time. The photo is used only to write your entry — it is not stored by Anthropic and is not used to train AI models.
Anthropic's privacy practices are described at anthropic.com/privacy.
Using Mira is always optional. You can write entries manually at any time.
Analytics and advertising
Folio collects no analytics, usage data, or crash reports. Folio contains no advertising of any kind.
Tips and in-app purchases
Folio offers optional tips as in-app purchases. All payments are processed by Apple. Folio never receives or stores your payment information.
Third-party services
- Apple iCloud — diary sync across your devices
- Apple App Store / StoreKit — optional tip purchases
- Anthropic — Mira's cloud AI writing feature, on devices without on-device AI, or by choice
No other third-party services, SDKs, or trackers are included in Folio.
Children's privacy
Folio is not directed at children under 13 and does not knowingly collect information from children.
Changes to this policy
If this policy changes in a way that affects how your data is handled, the date at the top of this section will be updated. Continued use of Folio after a change means you accept the updated policy.
