Terms of service
Last updated October 20, 2026. Operated by Forge Technologies, LLC ("we").
The service
Grimoire is a free, invite-only app for keeping track of a personal Magic: The Gathering collection, with optional sync between your own devices. By using it you agree to these terms.
Your account
You sign in with Google and need an invitation. Keep your devices secure; you are responsible for what is done through your account. One account belongs to one person.
Your content
Your collection data and card photos remain yours. You give us only the permission needed to store, sync and show them to you and to the people you choose to share with. Upload only photos of cards you scan; do not use the service to store anything else.
Acceptable use
Do not try to access other people's data, disrupt the service, probe it for weaknesses without permission, or use it for anything unlawful. We may suspend accounts that do.
Prices and card data
Card data, images and prices come from Scryfall, which reports market prices from third parties. They are for information only and may be out of date or wrong; do not rely on them for buying or selling decisions.
No warranty
Grimoire is provided "as is", without warranties of any kind. We work to keep your data safe and backed up, but we cannot guarantee the service will be uninterrupted or free of errors. Keep your own exports.
Limitation of liability
To the extent the law allows, we are not liable for indirect or consequential losses, or for loss of data or value, arising from your use of the service. Because the service is free, our total liability is limited to zero dollars, or the lowest amount the law allows.
Ending
You can stop using Grimoire and delete your account at any time. We may end the service or an account with notice where reasonable; you will be able to export your collection first.
