Deleting your data
AI Gallery has no accounts, so there is no account to delete. Your photos and videos are never uploaded: they stay in your phone's own gallery.
Delete what the app keeps on your phone
Uninstall the app, or open Settings → Apps → AI Gallery → Storage → Clear data. This removes the app's AI index (what it understood about each photo), the text it read from photos, places, albums, face data, settings and free-plan counters. Your photos are not touched. Copies made with "Save as phone folder" are ordinary photos in your Pictures folder and stay there.
Face data only: in the app, People → menu → Turn off People deletes every face and name at once.
Delete analytics and crash data
Google keeps analytics event data for no more than 14 months and crash reports for 90 days. To ask us to delete the analytics data linked to your installation sooner, email support@cybercodex.co.in with the subject "Delete my data"; we answer within 30 days.
Ads data
Reset or delete your advertising ID in Android Settings → Privacy → Ads. Ad networks then can no longer link new data to the old ID.
Purchases
Purchase records are kept by Google Play under its own policy. Cancel AI Gallery Pro in Google Play → Payments & subscriptions → Subscriptions.
