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.
| Cookie | Category | What it does | How long it stays |
|---|---|---|---|
| ck_session | necessary | Authenticated session JWT | 30 days |
| ck_consent_v2 | necessary | Stores your consent decision | 1 year |
| ck_locale | necessary | Display language preference | 1 year |

Analytics — off by default
If you opt in, we collect anonymous usage signals (which pages got visited, which buttons got tapped). No names. No emails.
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.
