A patient film camera for iPhone. Twelve frames a day, twenty-four hours
to wait, and a film stock you didn't choose.

Common questions

Where are my photos?
Captured photos appear in the Darkroom, where they develop over 24 hours.
Once developed, they move to the Roll. They never leave your device.

Can I see the photo before it develops?
No — that's the point. The wait is part of the camera.

Why only twelve photos a day?
A self-imposed constraint, like a single roll of film. The limit resets
24 hours after your first capture in any cycle.

Why didn't I get to choose the film look?
Each photo is randomly assigned one of six film profiles when developed.
The surprise is the design — embracing chance is the practice.

Can I export a photo?
Yes. Open any developed photo, tap the share icon (top right).

Privacy Policy

Last updated: April 2026

Liuguang stores all photos and metadata on your device. Nothing is
uploaded, sold, or shared with third parties — including the developer.

What we collect

Nothing. The app has no analytics, no telemetry, no account system, and
no network requests. Photos and their metadata stay in your device's
sandbox until you delete the app.

The app schedules background tasks on your device to develop photos while the app is closed. These run locally; no data is sent anywhere.

Permissions we request

Camera — to capture photos. Required for the app to function.

Notifications — to let you know when a photo has finished
developing. Optional; the app works without it.

Photos — to save developed photos to your library when you choose to export. Optional.

Third parties

None.
