What we use
A cookie is a small file a site stores in your browser. We use a single strictly-necessary cookie, plus your browser's local storage for a couple of conveniences. We do not set advertising or cross-site tracking cookies.
| Name | Type | Purpose | Duration |
|---|---|---|---|
castly_sess | Cookie (HttpOnly) | Keeps you signed in after login. Strictly necessary; without it the app cannot authenticate you. | Up to 30 days |
castly_history | localStorage | An offline copy of your recent project history, shown instantly and as a fallback. | Until cleared |
castly_key | localStorage | Optional legacy/manual API key for advanced use (not set for normal sign-in). | Until cleared |
No tracking by default
We do not use advertising cookies, social-media pixels, or cross-site trackers. If we ever add optional analytics, we will update this policy and, where required, ask for your consent first.
Managing cookies
The session cookie is required to sign in; blocking it will prevent the app from working. You can clear cookies and local storage at any time through your browser settings, and you can end your session with the Log out button in your account settings.
