1. About this policy
This Cookie Policy explains the browser technologies used by Mockupster, a mockup platform operated by Union United Network Inc., USA. It should be read with the Privacy Policy.
Some browser storage is technically different from a cookie. We describe local storage and session storage here because they help the site remember your sign-in and editor preferences.
3. Browser storage used by Mockupster
| Storage | What it is used for | How long it stays |
|---|---|---|
| Local storage | Supabase sign-in session, language selection, and editor preferences. | Until it expires, is replaced, or you clear Mockupster site data. The session contains access and refresh tokens. |
| Session storage | Temporary Google OAuth verifier and the requested return page during sign-in. | Scoped to the browser tab/session and removed by the app after the flow completes. |
These values support sign-in and the settings you choose; they are not advertising cookies. Clearing them may sign you out or reset preferences.
4. Authentication providers
Google Sign-In is handled through Supabase Auth. The sign-in flow temporarily stores a PKCE verifier in session storage so the authorization response can be exchanged securely. Supabase and Google may use their own cookies or storage while you are on their authentication pages.
Mockupster does not request access to unrelated Google services such as Gmail, Drive, Calendar, or contacts. See the Privacy Policy for the information returned by sign-in.
5. Analytics and advertising
No analytics SDK, advertising pixel, or separate product telemetry service was found in the current application code. Cloudflare, Supabase, and Google still receive the network requests needed to deliver the site, store account data, or complete authentication. Their platform-level logging and storage settings are managed separately from this website.
6. Your controls
You can clear cookies and site data through your browser settings. Clearing local storage signs you out and may remove language and editor preferences. You can also block cookies in your browser, though provider sign-in may not work as expected if you block storage required by Google or Supabase.
