Essential storage
RankLuma uses browser storage to keep requested account and workspace functions working. This includes local storage as well as cookies. These technologies are not all browser cookies.
| Storage | Purpose | Duration |
|---|---|---|
| Supabase authentication storage | Maintains your sign-in session and refreshes it securely. Stored in the browser by the authentication client. | Until sign-out, removal or session expiry; sessions may refresh while in use. |
| rankluma-business-draft (session storage) | Keeps the business you selected while you move to sign-in and setup. | Until cleared, completed or the browser session ends. |
| RankLuma request identifiers (local storage) | Prevents duplicate work when a report or request is interrupted. | Removed when the request is confirmed; unfinished identifiers may remain until storage is cleared. |
| rankluma_gbp_import_state cookie | Protects a Business Profile import authorisation request, when that feature is enabled. | Up to 10 minutes; cleared at callback. |
| rankluma_gbp_import_session cookie | Holds an encrypted, account-bound temporary Google import token. Secure, HTTP-only and SameSite. | Up to one hour; cleared after successful import. |
External services
If you choose Google sign-in, Google's own pages may use cookies under Google's policies. Map tiles or external listing links connect to their providers and may involve their own storage. These providers control their own websites; see the privacy policy for relevant disclosures.
Optional tracking
These essential functions are used to provide the service you request. We do not use Google account data for advertising. If we introduce optional analytics, advertising cookies or similar non-essential storage, we will describe it and obtain consent before use where required. A marketing-cookie acceptance is not required to sign in.
Your choices
You can sign out, clear RankLuma's site data or block storage in your browser. Doing so may sign you out, remove an unfinished business draft or interrupt duplicate-request protection. It does not delete account information held on our servers. Use the deletion instructions for account removal. Contact support@rankluma.app with questions.
