Delete your data · Cleavemark
Do not eat, lick, or ingest a specimen. Some minerals are toxic or radioactive. Handle unknown pieces with care, wash your hands, and avoid breathing dust. A photo identification is not guaranteed. It is not a valuation, an appraisal, or a legal decision about what you may collect, keep, or sell.
Cleavemark has no user account, so there is no account to delete. This page is the public data-deletion page for Cleavemark: AI Rock, Crystal & Fossil ID. It explains what Settings removes on this device, what the server still keeps, and how to ask us to delete those server records.
There is no user account
Cleavemark does not ask you to create an account. There is no sign-in, no email login, and no shared cloud container. The on-device collection stays on the device. The server does not keep a profile under your name.
Delete data on this device
In the app, open Settings, then Delete data on this device. Confirm when the app asks. That removes:
- the collection
- notes
- places
- the streak
- the on-device event log
Uninstalling the app also removes what Cleavemark stored on the device. Photos and files outside the app are left as they are.
What the server keeps
Deleting data on this device does not delete server records. The identify Worker keeps:
- quota counters keyed by the install id
- cached photo-set results, kept for up to 90 days
The install id is a random id the app creates on the device and uses for quotas. It is not an account. Photo bytes are not written to Workers KV. The cache stores the identification result for a photo set, not the photos. The same photos and the same notes are not processed again while that result is cached. Processing, when it happens, is done by the identify Worker with OpenAI or with Cloudflare Workers AI.
Ask us to delete the server records
Use Report a problem in the app. That link emails support@montgomeryappworks.com. Ask us to delete the quota counters and the cached photo-set results for this install. Send it from the device you want deleted, because those records are keyed by the install id and Cleavemark has no user account we can look up by name.
You can also email support@montgomeryappworks.com with the same request.
Subscriptions
Deleting data does not cancel a store subscription. An Apple or Google subscription stays active until you cancel it in the store. Apple subscriptions are managed at apps.apple.com/account/subscriptions. Google Play subscriptions are managed at play.google.com/store/account/subscriptions. Deleting the app does not cancel a subscription either. Purchases are handled by Apple or Google, with RevenueCat used to confirm the subscription.
