Jankrats is a free, non-commercial fan-made tool for tracking a Riftbound Trading Card Game collection, building decks, running local tournaments, and comparing collections with friends. It isn't affiliated with, endorsed by, or sponsored by Riot Games — see the notice above.
You can use most of Jankrats without an account. Signing in (with Google or Discord) unlocks syncing your collection/decks across devices and the Friends/social features. You're responsible for keeping access to your own account, and for anything posted under it.
Play nice. Don't use Jankrats to harass or impersonate other players, post content that's illegal or infringes someone else's rights, try to break or abuse the service (scraping at scale, attacking the backend, circumventing access controls), or use Riot's IP in a way their own policy above doesn't allow.
You keep ownership of anything you post — decks, pull photos, comments, your profile. Using Jankrats' social features (Friends, posts, comments) means that content is visible to other signed-in players, since that visibility is the whole point of those features. You can delete your own content at any time.
Jankrats relies on other companies' services to work — Google and Discord for sign-in, Supabase for the database, Anthropic's Claude for the AI card-scanning feature, and PostHog for basic usage analytics. Your use of Jankrats is also subject to those providers' own terms where relevant.
Jankrats is a hobby project, provided "as is," with no guarantee it'll be available, bug-free, or fit for any particular purpose. Card data, prices, and rules information are provided for convenience and may be incomplete or out of date — always check the official Riftbound rules/errata for anything that actually matters.
This project may change, or features may be added or removed, at any time — it's maintained casually, not under a support contract. Accounts or content that violate these terms may be removed.
