Processing on your device

Capture, RAW development, colour adjustment, photo management and export run locally. The app has no accounts, advertising, behavioural analytics, remote configuration or third-party crash reporting. It offers no online activation, downloadable paper resources or automatic cloud backup. Photos, adjustments, colour resources and local diagnostic logs are not sent to the developer.

Permissions and location

Camera permission enables capture; photo access supports the import and saving actions you choose. Location is optional and may be written into photographs when authorised. Refusing location does not prevent capture. Auto exposure may use Apple Vision on the device to estimate brightness in face regions; it does not identify people or save or upload facial features. Check location and personal details before sharing photographs.

System services

The app does not ask PhotoKit to download cloud originals or extra RAW decoding resources. Download cloud originals to the device first. When you choose Photos, Files, sharing or location services, iOS and the selected providers may connect according to your settings. The developer cannot access your accounts or cloud copies.

Storage and deletion

Originals, finished pictures, adjustments, colour resources and preferences are stored in the app’s local directory. Professional mode retains RAW until manually deleted. For new photographs taken after enabling everyday mode, a temporary RAW is removed only after the finished image is verified, keeping a full-size HEIF. If development fails, the RAW is retained. Older photographs keep their recorded retention policy.

Deleting inside the app does not delete exported copies. Uninstalling removes the app library. Export anything you want to keep first; the developer has no server backup to restore.

Diagnostics and support

Limited camera configuration, image dimensions, timestamps and error records may be stored locally, without automatic upload. You choose whether to share photos or logs for support. When you email us, we receive the address, message and attachments you provide to respond to your request. Email is processed by the email service provider.
