Cookie Policy

Biso uses only the browser storage it needs to work. We do not use advertising or analytics cookies, so there is nothing to opt out of.

What Biso stores in your browser

• Sign-in session: Firebase Authentication stores this in your browser to keep you signed in. It is needed for accounts to work.
• Learning progress: your XP, hearts, streak, chosen language, finished lessons and mistakes, saved under the name "viso.progress".
• Notice choice: a small note under the name "biso.cookieNotice", so that the cookie notice is not shown again.

Google sign-in

If you choose Continue with Google, Google and Firebase may set their own cookies in the sign-in window. Those are covered by Google's policies. If you sign in with email instead, this does not apply.

Your choices

You can clear this storage at any time in your browser settings, or erase your progress on the Account page. If you clear it, you will be signed out and your progress on that device will be lost. If you block it, sign-in and saving may not work.
