This Cookie Policy explains how Chatti uses cookies and local storage, and how you can manage them. It should be read together with our Privacy Policy.
Cookies are small text files stored by your browser. Local storage is a browser feature that stores data with no expiry date. We use both to keep you signed in and to remember your preferences.
We use the following categories:
We do not use advertising cookies, and we do not use Cloudflare's analytics.
The table below lists the cookies and local storage keys we use. Provider names link to their privacy policies.
| Name | Provider | Type | Purpose | Duration |
|---|---|---|---|---|
| sb-* | Supabase | Cookie / session | Authentication (OAuth session) | Session |
| i18n_locale | Chatti | Cookie | Remembers your language | 1 year |
| color-mode | Chatti | Local storage | Remembers your color mode | Persistent |
| sidebar / selected model | Chatti | Local storage | Remembers your sidebar state and selected model | Persistent |
| ph_* | PostHog | Cookie + local storage | Product analytics (no session recording) | 1 year |
| Sentry | Sentry | Cookie + local storage | Error tracing (no session replay) | 90 days |
| cookie-consent | Chatti | Cookie | Stores your cookie consent choices | 1 year |

We show a consent banner when you first visit. You can accept all cookies, keep non-essential cookies off, or choose which categories to allow. Strictly necessary cookies are always on because they are required to sign you in and run the Service.
You can change or withdraw your consent at any time by clearing cookies and local storage in your browser; the banner will appear again so you can choose again. Withdrawing consent does not affect the lawfulness of processing carried out before you withdrew it.
PostHog analytics and Sentry error monitoring load only after you give consent. If you reject or withdraw consent, they will not load.
We do not rely on browser Do Not Track (DNT) or Global Privacy Control (GPC) signals to disable cookies. We enable non-essential cookies only with your consent. You can also remove or reject cookies in your browser settings; disabling strictly necessary cookies may prevent you from signing in or using some features.
We may update this Cookie Policy from time to time. We will post the new version on this page and update the "Last Updated" date. Material changes will be notified through the Service or by email. We encourage you to review this policy periodically.
