What CardGrove is

A tool for keeping track of your Magic: The Gathering collection. It is offered as is, free of charge, and access is by invitation.

It is not a Wizards of the Coast project and is not affiliated with them. Card names, texts and artwork belong to their respective owners; they are used here only to identify the cards in your collection.

Your account

You are responsible for your password and for what happens under your account. If you suspect someone else has got in, change it from Settings.

The images you upload for your proxies are your business: only upload what you have the right to use.

You can delete your account whenever you want, from Settings. Everything in it goes with it —collection, decks, locations and uploaded images— and there is no bin to rescue it from, so export whatever you want to keep first.

Access to an account can also be closed without deleting it, while some problem is sorted out. Nothing of yours is touched in that case: it stays where it is and comes back untouched when the account is reopened.

Prices

The values shown come from Scryfall, which in turn takes them from Cardmarket. They are indicative and may be out of date or wrong. They are not a valuation and are not a basis for buying or selling.

No warranty

The service is provided without any guarantee of availability or of being free of errors. Keep copies of what matters to you: you can export your collection to CSV whenever you want, and it is worth doing now and then.

Changes

These terms may change if what the tool does changes. The date of the last revision is at the foot of this page.

What is stored about you

Your account: your email address, a name if you choose to set one, and your password hashed with bcrypt. The password is never stored in the clear and nobody — including whoever runs the server — can read it.

Your collection: the cards you record, their condition and language, where you keep them, what you paid if you note it down, your decks, the images you upload for your proxies, and any notes you write.

Usage: a log of your inventory movements — additions, moves, removals — which is what makes it possible to undo a whole import. There is no analytics, no profiling, no browsing tracking.

What it is used for

Only to run the service: signing you in, showing you your collection, and working out what a deck is missing.

It is not used for advertising, not passed to third parties, and not sold. There are no marketing emails.

Who else sees anything

Card artwork is served by Scryfall straight to your browser from cards.scryfall.io. That means Scryfall receives your IP address when those images load, as with any image hosted elsewhere. It does not receive which cards you own or who you are.

Your proxy images are stored on this server's own storage, not on an external service.

Magic catalogue data comes from Scryfall, but the server downloads it, not your browser.

How long

For as long as you keep the account. If you ask for it to be deleted, everything hanging off it goes too: lots, decks, locations, imports and proxy images.

Your rights

You can access your data, correct it, export it and delete it. Neither the export nor the deletion has to be asked of anyone: you can download a CSV of everything from the collection page whenever you want, and from Settings you can delete your account with everything in it, images included.

For anything else, write to info@cardgrove.app. If you believe your data is being mishandled, you can complain to your national data protection authority.

Contact

There is no company behind this: CardGrove is a personal project run by one person, so a reply may take a few days.
