Cookie Policy
What we store on your device and why.
Last updated:
1. Overview
Cookies and similar browser-storage mechanisms (localStorage, sessionStorage) let websites remember you between visits and measure how the site is used. grith.ai uses a small, defined set of them, listed below. For the full picture of how we handle personal data, see our Privacy Policy.
We set no advertising, tracking, or analytics cookies, so there is no consent banner on this site. Everything we store is strictly necessary or a preference you set yourself, and our page-view analytics is cookieless.
2. Categories we use
2.1 Strictly necessary
These are required for the site to function. They do not need your consent under UK GDPR / PECR.
| Name | Set by | Purpose | Lifetime |
|---|---|---|---|
grith-theme | grith.ai (localStorage) | Remembers whether you chose the light or dark theme. Set only when you use the theme toggle, and never leaves your device. | Until cleared |
better-auth.session_token (with a __Secure- prefix in production) | grith.ai (httpOnly cookie) | Authenticates you when signed in. Required for the dashboard, account, and billing pages. | Up to 7 days; refreshed or removed as your session changes |
2.2 Analytics (cookieless, no storage)
We count page views using Cloudflare Web Analytics. It is cookieless by design: nothing is written to or read from your device - no cookie, no localStorage entry, no sessionStorage entry - and it sets no identifier of any kind. Cloudflare also does not fingerprint you from your IP address or user-agent string.
Because there is no identifier, you are not recognised between page loads or between visits, and no profile is built. What we see is aggregate counts: page views, which sites referred you, country, browser, and device type.
Since this involves no access to information stored on your device, it falls outside the consent requirement in PECR regulation 6, which is why this site has no cookie banner. Our lawful basis under UK GDPR is legitimate interests (understanding aggregate site usage). Cloudflare acts as our processor and retains these aggregate counts for up to 6 months.
3. How to control cookies
- There is no banner to answer. We set no consent-requiring cookies, so there is nothing for you to accept or decline. If that changes, we will add a banner and update this page.
- Your browser can block or delete cookies and site storage globally. Doing so will sign you out, disable any account features that depend on persistent state, and reset your theme choice.
- Blocking analytics. If you would rather not be counted at all, any content blocker that blocks
static.cloudflareinsights.comwill stop the measurement script loading. Nothing else on the site depends on it. - Do Not Track / GPC. Our analytics collects no personal data and we neither sell nor share data with anyone, so the Global Privacy Control and Do Not Track signals have nothing to opt you out of here. We do not run behavioural advertising, cross-site tracking, or any other processing those signals are designed to stop.
4. Updates
We'll update this page if we add or remove a cookie or change a provider. The "Last updated" date at the top reflects the current version.
