Cookies are small text files stored on your device by your browser when you visit a website. They let the site remember things like that you are signed in. "Local storage" and "session storage" are related browser technologies that serve similar purposes. This policy covers all of them, and we refer to them together as "cookies."
Clarity Books AI uses the minimum number of cookies needed to run the Service. We do not use advertising cookies. We do not use third-party cross-site tracking. We do not sell or share data derived from cookies with data brokers or advertisers.
| Name | Type | Purpose | Duration | Provider |
|---|---|---|---|---|
| sb-access-token | Strictly necessary | Keeps you signed in. Without it, you cannot use the Service. | Session (~1 hour, rotated) | Supabase (first-party) |
| sb-refresh-token | Strictly necessary | Refreshes your session without asking you to sign in again. | Up to 30 days | Supabase (first-party) |
| sb-* | Strictly necessary | Other Supabase auth metadata (PKCE verifier, OAuth state, etc.) used during sign-in flows. | Session — short-lived | Supabase (first-party) |
| pwa-install-dismissed | Preferences | Remembers that you dismissed the "install app" prompt so we do not nag you again. | Local storage — persistent until cleared | First-party |
| notify-prompt-dismissed | Preferences | Remembers that you dismissed the notification-permission prompt. | Local storage — persistent until cleared | First-party |
| vercel-analytics | Analytics (first-party) | Aggregated, privacy-friendly usage analytics (page views, performance). No cross-site tracking. No user fingerprinting. | Session | Vercel Web Analytics |
If this list changes materially, we will update this page and, where required by law, ask for your consent before new cookies are set.
Strictly necessary
Required for the Service to function. Without these, you cannot sign in, stay authenticated, or use the application securely. Consent is not required by law for strictly-necessary cookies.
Preferences
Used to remember choices you have made so the interface does not repeatedly ask you the same thing. These are first-party only.
Analytics (first-party only)
Used to understand how the Service is used in aggregate — which pages load slowly, which features people use, where errors happen. Our analytics tool (Vercel Web Analytics) does not use third-party cookies, does not build user profiles, does not fingerprint devices, and does not share data across sites.
Advertising / tracking
Not used. Clarity Books AI does not serve ads, does not target ads, does not embed third-party ad pixels, and does not participate in any cross-site advertising network.
Note: disabling strictly-necessary cookies will prevent you from signing in or using the Service.
The Service is intended for users 18 and older. We do not knowingly set cookies or collect data from children.
We will update this page when the cookies we use change. The "Last updated" date at the top reflects the most recent revision.
