Privacy Policy

For the iPhone app Dayprose (字里光阴). Effective October 14, 2026.

Dayprose turns the photos in your library into books. Your photos and books stay on your iPhone. We do not collect, upload or have access to them. Dayprose has no accounts, no ads and no third-party analytics or tracking.

On-device processing

With your permission, Dayprose reads the date, location and size of your photos to build an on-device index. Scene search and face recognition run on your iPhone; scene and face features, and the names you give to people, are stored only on your device. Your books are stored in the app's local storage and are included in your own device backups.

When data leaves your device

  • Place names: photo coordinates are sent to Apple's geocoding service to look up place names. Photos themselves are not sent.
  • AI writing: captions are written on device by default. Only when you tap “AI 精写” on a page are that page's photos, downscaled, and its text sent to Apple's Private Cloud Compute to generate the caption. Apple states that this data is used only to fulfil the request and is not stored.
  • Model downloads: models are downloaded from our server hosted on Cloudflare, and the optional offline writer may be downloaded from Hugging Face. These servers keep standard access logs such as IP addresses.
  • Export and sharing: files you export or share go wherever you choose.
  • Importing books: when you import a shared book that includes photos not found in your library, those photos are saved to an album named “字里光阴”.

Purchases

Subscriptions and unlocks are purchased through the App Store. Apple processes payments; we never receive your payment details.

Children

Dayprose is not directed to children under 13 and does not knowingly collect personal information from anyone.
