Cookie Policy
Last updated: August 15, 2026.
The short version
Tredecim doesn't use tracking or advertising cookies. There is exactly one cookie, and it exists to keep you signed in — nothing else.
The one cookie we actually set
- Session cookie. An httpOnly cookie containing a signed reference to your account, set when you verify a wallet. It can't be read by JavaScript, and it isn't used to track you across other sites — its only job is remembering that you're signed in.
What we deliberately don't use
No advertising cookies, no third-party tracking pixels, no analytics cookies that follow you around the web. If that ever changes, this page will change with it — and it would be a real, disclosed change, not a silent one.
Third parties
Stripe (payments) and Vercel (hosting) may set their own cookies as part of operating their services — those are governed by their own policies, not this one. Tredecim itself doesn't add anything on top of what those providers require to function.
Theme preference (not a cookie)
If you switch between dark and light mode, that choice is saved in your browser's localStorage, not a cookie. It stays on your device, is never sent to our servers, and isn't used to track you — it just remembers which theme you picked. Clearing your browser's site data resets it to your system's default.
Your choices
Since there's only one cookie and it's required to stay signed in, there's no cookie preference center here — blocking it just means you'll need to sign in again each visit. Your browser's own cookie settings still work normally regardless.
