Privacy

Last updated October 30, 2026

Teseria collects as little as it can. There are no ads, no analytics and no third-party trackers on this site.

What we collect

• Your account. When you sign in with GitHub or Google, we get your name, email address and profile picture from them, plus the sign-in tokens they issue. If you sign in with a link sent to your email, we store the address you give us.
• Your sessions. While you're signed in, we keep your IP address and browser type with the session, to keep you signed in and to stop abuse.
• Your purchases. Dodo Payments runs checkout and collects your payment details under its own privacy policy. We never see your card. Dodo tells us which plan you bought, its status and when it renews.
• Your saved elements. The list of elements you save to your account.

On your device

Signing in sets one cookie that keeps you signed in. Your theme and sound settings stay in your browser's local storage and are never sent to us.

Who else sees it

We never sell your data. We share it only with the services that run Teseria: GitHub and Google for sign-in, Resend for sending sign-in emails, Dodo Payments for billing, and the provider that hosts our server and database.

How long we keep it

We keep your account until you ask us to delete it. Deleting it removes your profile, sessions, saved elements and plan records from our database. Dodo keeps its own billing records for as long as the law requires.

Your choices

You can ask for a copy of your data, a correction, or its deletion at any time. Email [email protected] from the address on your account and we'll handle it within 30 days.

Children

Teseria is not meant for anyone under 16, and we don't knowingly collect their data.

Changes

If this policy changes, we'll post the new version here and update the date at the top.
