Cookie Notice
Version 1 - 2026-05-30
This notice explains the cookies Nullcrest uses. We use only strictly-necessary cookies and set no tracking, advertising, or analytics cookies. Because every cookie we set is strictly necessary to provide the service you asked for, no cookie-consent banner is required.
1. Strictly-necessary cookies
These are set by our authentication service and are required for the service to work:
| Cookie | Purpose | Type |
|---|---|---|
| frogauth_refresh | Keeps you signed in across requests. | Session / authentication |
| frogauth_csrf | Protects against cross-site request forgery. | Security |
2. No non-essential cookies
We set no tracking, advertising, analytics, profiling, or third-party cookies. We do not embed third-party pixels or trackers.
3. Cookieless acquisition funnel
When you arrive on our landing page we record a cookieless attribution beacon. It uses no cookie and stores no readable identifier: it records any campaign parameters in the link you followed, plus a hashed IP address, a hashed user-agent, and the referring host. This lets us understand which campaigns bring visitors without tracking individuals. These records are kept for a maximum of 30 days, then purged.
