CardTome Privacy Policy

Plain language first: your collection stays on your phone. This page names the few moments data leaves it, and what happens then.

Starter document. This page is plain-language starter language, published so the app has a policy in place from day one. It has not yet been reviewed by an attorney and will be updated once that review happens.

The short version

CardTome is a collection keeper for trading cards. Your collection lives on your device — we have no account system and no server copy of it. We never sell personal information, run ads, or track you across apps.

What is stored on your device

The cards you add — names, sets, quantities, conditions, prices you enter, and card photos you save — are stored in the app's own storage on your phone. Nothing in your collection is uploaded to us. If you delete the app, that data is deleted with it, so keep your own backup of anything you can't replace (the app can export your collection as a CSV file on the Pro plan).

Camera and card photos

CardTome uses the camera to photograph your cards. When you add a card by photo, the text on the card (its name and collector number) is read on your device using on-device text recognition (Google ML Kit). Card photos used this way are not transmitted to us or to any server.

Card searches and market prices

When you search for a card, the app sends your search terms (such as the card's name and number) to TCGdex (api.tcgdex.net) and shows the matching cards and their market prices, which TCGdex sources from TCGplayer and Cardmarket. No name, account, or device identity is sent with a search — there is no account to send.

Purchases and subscriptions

CardTome Pro is sold through the App Store or Google Play and processed by our purchase provider, RevenueCat. RevenueCat receives your purchase record and an anonymous app user ID generated by the app (not your name or email) so your subscription stays active across reinstalls, and may collect device information needed to prevent fraud. Your payment details go to Apple or Google only — we never see your card number. Subscriptions renew automatically until cancelled in your store account settings.

What we never do

No advertising. No sale or rental of personal information. No cross-app or cross-site tracking. No analytics profiles built about you.

Children

CardTome is a general-purpose collecting tool and does not knowingly collect information from children.

Changes to this policy

If we change how the app handles data — for example, by adding a feature that sends data somewhere new — we will update this page with a new effective date before that change ships.
