Privacy Policy
OP Grandline TCG is a free fan-made simulator. We're players, not a data company — we keep only what the game needs to run, and nothing else. Questions? Ask us on Discord (our only contact channel).
Playing as a guest
No account needed. The game just keeps an anonymous session token (a random id so you can reconnect to a match, gone after 180 days) and a random device id. Your settings stay on your device. Game logs only record card plays — never anything about you.
If you create an account
Then we store your email (only for logging in — we never send mail), your password as a bcrypt hash, your display name, your decks and your win/loss record. That's the whole list.
What other players see
Your display name, on the leaderboard and in finished-match replays (which anyone with the room code can view for up to 30 days, then they're wiped). There's no chat — just a fixed set of emotes — so nothing you type is ever shown to anyone.
Cookies & third parties
One cookie (optcg_id), which holds your session. No tracking cookies.
Card images load straight from Bandai's official servers and, in the browser, one
graphics library loads from the jsDelivr CDN — like any web request, those servers see
your IP. We send them nothing about you.
What we don't do
No analytics, no ads, no crash reporting, no purchases, no selling or sharing your data — and the app can't touch your location, camera, contacts or files. Our own code doesn't log IPs (standard hosting logs may exist, as everywhere on the internet).
Deleting your data
Delete your account any time from the main menu — email, name, decks and ranking go immediately, and your name is scrubbed from replays. Details on the deletion page. Anything else (a copy of your data, a question): Discord, and we'll sort it.
