Privacy policy

Effective8 November2026. Gobling Company provides Halvane Pattern Cleanup for Android.

Local image processing

The app stores normalized working image copies, project names, source hashes, selected frequency pairs, processing parameters and saved treatments in app-private storage. It has no app network permission, account, ads, analytics SDK or automatic Android cloud backup. We do not receive your images through the app.

Import and exported files

You select files and destinations through Android Files. A chosen cloud-backed provider may transfer them under its own policies. Exported images contain your image content; comparison images also contain the working source. Settings JSON and ZIP include project names, hashes, selections and saved treatments. Original image metadata is omitted from normalized PNG output.

Retention and protection

Delete a project to remove its index entry and working image. Failed image cleanup can be retried. Resetting an unreadable index retains image files until cleanup. Clearing cache removes generated exports; clearing app data or uninstalling removes local work. Save external files and keep originals first. No separate app lock or app-managed encryption is provided; Android sandbox and device protections apply.
