What we hold
Union Arena tournament records: who entered an event, how they finished, and what they played. Most comes from Bandai's TCG+ platform, the rest from members submitting results by hand. For each entrant we store the TCG+ account name and Bandai membership number that TCG+ published, plus their record. We keep it after Bandai stops showing it, about a year after an event.
The account name is a Bandai display name, not a real name. We hold no addresses or birthdates.
A screenshot sent with a member number claim is kept until the claim is decided, then deleted.
If you sign in
Sign-in is Discord only. We store your Discord id, username, email address and avatar, and a session for each signed-in browser. Expired sessions are deleted within the hour.
An account also holds the locations saved on it, the TCG+ member number linked to it, and the member number claims sent from it with their outcome.
An account can be deleted from the account page. Deleting it removes its sign-in, sessions, saved locations, member number link and claims. Results and decklists it submitted stay, and the activity log keeps its entries under "Deleted account". Summaries already in the activity log keep the names they were written with, such as "Made Alice a standings helper". Admin notes on other members' claims and flags on other accounts keep any mention of it as written.
The standings helper
The standings helper is an optional browser extension. It reads your Bandai TCG+ login in your own browser and sends us event standings and your match history. Your TCG+ login never reaches our server. It holds one token this site issues when you pair a device.
Our use and transfer of the data the helper handles complies with the Chrome Web Store User Data Policy, including the Limited Use requirements.
Everything else
Reports and their contents are stored in our database, including an optional Discord username when one is provided. When a report webhook is configured, we try to notify a private Discord channel after each report is stored. Report IP addresses are used in memory for rate limiting and never stored. No analytics, trackers or ads. Cookies keep you signed in and remember whether you view national results or your saved scope. Discord, Fly.io and Cloudflare process data on our behalf. Nothing is sold.
