Privacy policy

Anyone can use flinttype without an account. The practice surface, drills, and races all run without ever introducing yourself. Your typing stays in the browser unless you sign in or join a race (see third parties).

Signing in (via Clerk) lets us store your typing history, personal-best tracker, adaptive-drill model, a short analysis of each test, and preferences on our database so they survive between sessions. That information is yours: request an export or deletion any time.

For signed-in users.

Account creation goes through Clerk. We receive only what you give Clerk: an email address, optional username and display name, and the OAuth identifier from your social provider if you used one. Passwords never reach our servers; Clerk handles authentication entirely.

We mirror the minimum identity fields (Clerk user id, display name, email-localpart) into our database so we can attach your typing history to a stable handle. Email addresses are not surfaced publicly.

Every completed test stores a row with its start and end times, the kind of test and its length, your speed and accuracy, how many mistakes you made, and how many times you restarted before finishing.

While you're signed in, each test also keeps a short summary of how its time was spent: typing, fixing mistakes, pausing before words, hesitating inside words, and breaks. It also holds a few timing averages, such as your usual time per key and per kind of key move, and the timing of up to 16 letter pairs. It records whether your keyboard behaved like QWERTY, never which keys you pressed. The summary doesn't include the text you typed or the order of your keys. Per-keystroke timings are used once, to build this summary and to update your practice model, and are then discarded.

Your practice model and these summaries are private. Only you can see them, on your Insights page, your result screens and the technical view. Your public profile shows your test results, never your weak letter pairs, words or timing figures. You can delete your typing analysis at any time from the Insights page. We don't sell, syndicate or share any of it.

When you're signed in, friends who follow you back can watch your practice live while you type. While you share live, the test you're on, including its keystrokes, is sent to them and kept until your next live test replaces it. It's on by default; turn it off, or hide from particular friends, in Multiplayer & social settings.

Theme, caret style, font, keyboard layout, and similar customisation live in two places: a copy in your browser's localStorage (so the page paints with your choices on the next visit, no flash) and a copy in our database when you're signed in (so the same choices follow you to a new browser).

We use Clerk's session cookie to keep you signed in. No advertising cookies, no analytics scripts that load before consent, no third-party trackers.

The services flinttype runs on:

• Clerk: sign-in, sessions and your account details.
• Discord: only if you choose Continue with Discord. Discord shares your account id, username and email with Clerk to sign you in.
• Vercel: hosting and CDN. Server logs include request paths and IP addresses; we don't aggregate or export them.
• Neon: managed Postgres for the typing-history database.
• Railway: the live race server. While you race, your progress (how far you've typed and your speed) and your IP address pass through it, signed in or not. Race rooms live in memory and are gone once the race ends.
• OpenRouter: only when you use Design with AI. The words you type there and a snapshot of your current appearance settings go to OpenRouter, which passes them to an AI model to suggest a look.
• MonkeyType: only if you import from it. We keep your Ape Key encrypted so your profile can pull in new results, and use it only to read your MonkeyType results.

Export your data, delete your account, or correct what we have on you: open an issue on GitHub or email the address in the repo. We'll act within a reasonable window. Account deletion removes your test rows, preferences, adaptive model, and the Clerk-mirror identity row.

Flinttype isn't directed at children under 13. If you believe a child has signed up, contact us and we'll remove the account.
