Delete your Lithico account
Last updated: 4 October 2026
This page explains how to delete your account in Lithico: Rock & Crystal ID, published by Park Tech Systems, and what happens to your data when you do.
Delete your account in the app
- Open Lithico and go to the Settings tab.
- Scroll to Your data and tap Delete account.
- Confirm. Deletion happens immediately and cannot be undone.
Want to keep a copy first? In the same section, Export my data downloads your collection, scan history and test results.
What is deleted
- Your account and profile, including any email address you linked;
- every scan and every photo you uploaded;
- your collection, notes and find locations;
- your guided-test answers.
All of it is removed from our database and file storage straight away. We keep no copy and there is no retention period.
What is kept
- Subscriptions are billed by Apple or Google. Deleting your account doesn't cancel a subscription. Cancel it in your App Store or Google Play subscription settings. Their purchase records are kept by them under their own policies.
- Contributed specimens. If you opted in to contribute specimens to the reference library, material you already contributed may remain in that library, as the Privacy Policy explains.
Delete only some data
You don't have to delete your account to remove data. In the app you can delete any single scan or collection item, which removes its stored photo too, or use Settings → Your data → Delete all photos.
No longer have the app?
Email pfolvig@gmail.com with the subject "Lithico account deletion", from the email address you linked to your account. We'll delete the account and its data within 30 days and confirm by reply. An account that was never linked to an email can only be deleted from the app, because there's nothing else we can use to identify it.
