Without an account
You can use LoSTrainer without signing in. Your best scores and completed lessons are then stored only in your own browser (local storage). We receive nothing.
With an account
When you sign in with Discord or Google, we store your name, email address and profile picture from that service, the username, server and main class you choose, your best scores, completed lessons and statistics, and the maps you publish. Only your username, server, main class, leaderboard scores and published maps are shown to other players; your name and email address are never shown. We use this only to keep your progress across devices. We never post anything on your behalf and we do not share or sell your data.
Where it is stored
The site runs on Vercel and accounts are stored in a Neon Postgres database. Sign-in cookies are only used to keep you signed in. There are no ads and no tracking cookies.
Deleting your data
You can delete your account and all saved progress at any time on your account page. Progress in your browser can be removed by clearing this site's data in your browser.
