Your cookies, your call
A friendly tour of what's on your device when you use ClassKasa - and how to change it any time.
We keep this short. There are exactly three things going on, and only the first one is mandatory. The rest is yours to decide.
Necessary - always on
These keep the site standing up. Login session, language preference, and the cookie that records your other choices.

Analytics - off by default
If you opt in, we use Contentsquare (an EU-based analytics tool) to record replays of how the site is used and build heat-maps of taps and scrolls, so we can see which pages help and where people get stuck. Your personal details - names, amounts, bank numbers - are blanked out on your device before anything reaches Contentsquare. No opt-in means no recording.

|---|---|---|---|
| _cs_id | Analytics | Contentsquare - a pseudonymous id for this device (no name attached) | 13 months |
| _cs_s | Analytics | Contentsquare - counts the page views in this visit | 30 minutes |

Marketing - off by default
If you opt in, we let Facebook and Instagram know you visited so they can show our app to other parents like you. Your email is hashed before it ever leaves your browser.
