Cookie policy
Last updated: May 21, 2026
Algo School uses cookies only for things that have to work for the site to work — keeping you signed in, remembering which child is using a shared device, and confirming you've seen this notice. We do not use cookies for analytics, advertising, or tracking, and we do not share any cookie data with third parties.
Because every cookie here is strictly necessary, there is no "Reject" option — turning these off would prevent you from signing in or using the site at all. If you'd rather not have any cookies set, the best path is to not create an account.
Cookies we set
| Name | Purpose | Lifetime | Scope |
|---|---|---|---|
algo_session |
Signs you in. Holds the encrypted session token. Without this you'd have to log in on every page. | 24 hours | HttpOnly, SameSite=Lax, the whole site (/) |
algo_kid_devices |
Remembers up to six children who have signed in on this device, so the kid-login page can show their avatars instead of asking them to type their name every time. Only the student IDs — no names, no PINs. | 90 days | SameSite=Lax, only the kid-login pages (/kids/) |
algo_cookie_ack |
Records that you've seen the cookie banner on this device so we don't keep showing it. Set when you tap "Got it". | 12 months | SameSite=Lax, the whole site (/) |
What we do NOT do
We do not set analytics cookies (no Google Analytics, no Mixpanel, no Posthog), advertising cookies, social-network cookies, or any third-party tracker. The three cookies above are the only ones this site puts on your device.
Payments go through Stripe in a separate window — Stripe sets its own cookies on its own domain to keep your checkout secure. We never see those cookies and we don't store any payment information ourselves. See our privacy policy (coming soon) for more on how we treat your data.
Clearing cookies
You can clear any of these from your browser's settings at any
time. Clearing algo_session will sign you out;
clearing algo_kid_devices will reset the kid-login
avatar memory on this device; clearing algo_cookie_ack
will make this notice appear again.
