Privacy Policy
Effective 28 October 2026
Who we are
Grain – Pro Film Camera ("Grain", "the app") is a camera app for iPhone made by Nikunj Singh, an independent developer ("we"). This policy explains what happens to your information when you use it.
Information we collect
None. Grain does not collect, store, transmit, sell or share any personal information. It contains no analytics, advertising, crash-reporting or other third-party code, and it makes no network connections, so nothing you do in the app can reach us or anyone else.
Permissions the app asks for
- Camera – to show the viewfinder and take photos and videos.
- Microphone – to record sound with your videos. It is only used in video mode.
- Photos – to save your photos and videos into a "Grain" album in your photo library. Grain doesn't read or upload your other photos.
You can change these at any time in the iPhone's Settings › Privacy & Security. Grain works without the microphone; it needs the camera to take pictures and Photos access to save them.
What stays on your iPhone
- Photos and videos you take, saved to your photo library (and, if you choose, the RAW DNG files alongside them).
- Your settings and film edits, kept in the app's own storage on the device.
- .cube LUT files you import, kept in the app's folder, which you can see in the Files app.
We never receive any of this. If you back up your iPhone with iCloud or a computer, that backup is handled by Apple under Apple's privacy policy, not by us.
Deleting your data
Delete photos and videos in the Photos app. Delete imported LUTs in Grain's Settings › Manage films, or in the Files app. Deleting Grain removes its settings and imported LUTs from your iPhone.
Children
Grain is suitable for all ages. Because it collects no information, it collects none from children.
Changes to this policy
If this policy changes, the new version will be posted on this page with a new effective date. If a future version of Grain ever needed to handle personal information, this page would say so before that version is released.
