Cookies
Updated: July 11, 2026
CHLLM only uses cookies needed to run the service. No advertising cookies, no cross-site tracking, no data resale.
The three cookies we set
| Name | Lifetime | What it does |
|---|---|---|
| chllm_session | 7 days, extended as you use the service | Keeps you signed in. The server only stores a fingerprint of it. |
| chllm_csrf | Browser session | Security: checks that actions really come from you (CSRF protection). |
| lang | 1 year | Remembers your display language. |
These cookies are strictly necessary, or simple display preferences. Regulations do not require consent for them — which is why there is no cookie banner on this site.
The rest
- Audience measurement uses Plausible, hosted in the European Union: no cookies, no individual identifiers, aggregated statistics.
- Your browser keeps a few preferences locally (theme, language, guided tour). They never leave your device.
- Payment happens on Stripe’s page (stripe.com), where Stripe’s own policy applies.
