Mímir Lens uses no advertising cookies, no analytics trackers, and no third-party marketing technology. Everything we store in your browser is strictly necessary to make the app work, which is why we do not show a cookie consent banner (consent is not required for strictly necessary storage under the ePrivacy rules).
| Storage | Purpose | Lifetime |
|---|---|---|
| Session token (localStorage) | Keeps you signed in to your account. | Up to 90 days; removed on log-out. |
| App preferences (localStorage) | Remembers choices such as your saved court corners, match format, scoring mode, and whether you have seen the intro tour. | Until you clear site data. |
| Match videos (IndexedDB, on-device) | Game-mode rally clips, the match safety tape, and an upload outbox so a match survives a bad network. This footage stays on your device — it is browser storage, not a cookie, and is never read by us from your browser. | Clips/tape roughly a week (bounded by size caps); outbox until delivered. |
| Admin cookie | Signed cookie for the operator's admin panel only. Regular players never receive it. | 8 hours. |
You can clear everything we store at any time via your browser's "clear site data" controls. Doing so signs you out and deletes any match videos still cached on the device (your account, analyses, and anything the Terms say we store server-side are unaffected). Blocking storage entirely will prevent signing in.
