Email fourvault@otchealth.app. A real person reads it. If you are a parent asking about your child's data, say so and we will prioritise it.
For parents
How do I see what you hold about my child?
Email us from the account address and ask. You can review it, ask us to delete it, and refuse any further collection. See the Privacy Policy for what we collect, which is deliberately very little.
How do I delete a child profile or the account?
Both are in Parent Settings in the app. Deleting a child removes that child's profile, vaults, cards, valuations, trades and friend links. Deleting the account removes the family and everything under it. It cannot be undone, and it does not cancel app store billing.
Can my child buy something by accident?
No. Every purchase sits behind a parental gate a child cannot pass alone, and there are no loot boxes or randomised paid mechanics anywhere in the app.
Is there advertising?
No. There is no advertising and no third-party analytics on any screen a child sees.
Using the app
A card was recognised incorrectly.
Recognition works from a photo and is not perfect. Retake the photo in even light with the whole card in frame. If it is still wrong, email us the card name and we will look at it.
A card value looks wrong.
Values are estimates, and on the free tier values outside our verified sets are labelled as not market verified. Treat them as a rough guide, not an appraisal.
How do I cancel a subscription?
Subscriptions are billed by your app store, so cancel there. We cannot cancel or refund an app store subscription for you.
