Cookies and Browser Storage
This page explains the first-party cookies and browser storage the current Clipo application uses, why each item exists, how long it remains, and the controls available to you.

Cookies Clipo sets
The current Clipo application uses two first-party cookies:
| Cookie | Purpose | Lifetime |
|---|---|---|
| clipo_google_session | Holds a signed Google-account session so an authenticated user can access batch processing. | Up to 30 days; signing out expires it. |
| clipo_google_oauth_transaction | Protects the Google sign-in exchange with signed state, nonce, and PKCE transaction values. | Up to 10 minutes; cleared when the callback completes. |
Both cookies are HttpOnly, SameSite=Lax, and marked Secure in the production environment. Browser scripts cannot read them. The OAuth transaction cookie is restricted to the sign-in callback path.
Local storage device identifier
Clipo stores a randomly generated pseudonymous identifier underclipo-device-idin local storage. It helps apply service analytics and rate limits to a browser. It is not an advertising identifier and does not contain your name or email address.
The identifier remains until Clipo site data is cleared in the browser. Signing out or deleting a saved image result does not remove it. Service records associated with the identifier are used for reliability, rate limiting, abuse prevention, and security review.
IndexedDB image results
Clipo uses an IndexedDB database namedclipo-resultsto keep original images, transparent results, cutouts, masks, filenames, reliability information, and creation times in this browser. This allows the result page to display and download your files.
Automatic expiry is not enabled. Use “Delete this result” or “Clear all saved results” on the result page, or clear Clipo site data in browser settings. Clearing cookies alone may not clear IndexedDB.
If IndexedDB is unavailable, a result may be held only in page memory for immediate download. That temporary copy disappears after the page is closed or reloaded.
Advertising, analytics, and third parties
The current Clipo web application does not implement advertising cookies, cross-site tracking pixels, or optional third-party browser analytics cookies. Because no optional cookie category is currently enabled, Clipo does not display a cookie-preference banner.
If you choose Google sign-in, your browser leaves Clipo for Google. Google may use cookies or other storage on its own domains under its own terms and privacy practices. Clipo's first-party cookies listed above are separate from Google's storage.
Your controls and their effects
- Use one-image processing without Google sign-in and without the 30-day session cookie.
- Sign out to expire the Clipo session cookie; this does not delete local results or the device identifier.
- Delete individual results or clear all saved results from the result page.
- Clear all Clipo site data in browser settings to remove cookies, local storage, and IndexedDB together.
- Blocking required browser storage may prevent sign-in, batch access, rate-limit identification, or result persistence from working.
Changes to cookie use
If Clipo adds optional analytics, advertising, personalization, or other non-essential browser storage, this page and the consent experience must be updated before that storage is enabled where consent is required.
This page should be reviewed whenever cookie names, purposes, lifetimes, consent choices, or browser-storage behavior materially change.
