Cookie notice

Last updated 15 November 2026

tendi uses no advertising, analytics or tracking cookies of its own. It stores a small amount of data in your browser so your progress and preferences are still there tomorrow.

What tendi stores

Name What it is for Lasts
tendi_rewards (cookie) Your XP total and streak. Up to 400 days, renewed when you practise
IndexedDB Your daily progress and results on this device. Until you clear site data
tendi:settings (local storage) Interface language, language you practise, difficulty and theme. Until you clear site data

These are strictly needed to provide the features you asked for, so under the UK PECR and EU ePrivacy rules they do not need your consent. They are never sent to advertisers, and the cookie is only ever read by this site.

YouTube

Clips play through YouTube's embedded player, in YouTube's privacy-enhanced mode (youtube-nocookie.com). In this mode YouTube says it sets no cookies. When a practice screen loads the player, YouTube (Google) still receives information such as your IP address, and once a clip plays it may keep data in your browser's local storage. We don't control or receive it. See how Google uses cookies. If you'd rather not allow that, don't open a practice screen, or block third-party cookies and site data in your browser (the clips may then not play).

Your choices

  • Clear cookies and site data for tendi.club in your browser settings. This resets your streak, XP, progress and settings.
  • Block third-party cookies and site data to limit what YouTube can store.

More about how we handle data is in the privacy policy.
