TuneLens uses a small number of browser storage mechanisms to make the app work. We do not use advertising cookies or third-party tracking cookies.
| Name | Provider | Purpose | Duration |
|---|---|---|---|
sb-*-auth-token |
Supabase | Keeps you signed in between page loads. Required for the app to function. | Session / until sign-out |
These cookies are strictly necessary. The app cannot function without them and no consent is required under ePrivacy rules for essential cookies.
TuneLens also uses your browser's localStorage — not cookies — for a small amount of non-personal preference data:
| Key | Purpose |
|---|---|
tl-theme |
Remembers your dark/light mode preference. |
tl-checklist-* |
Remembers which technical fix items you have checked off in a mix analysis session. |
localStorage data is stored only in your browser and is never sent to our servers. You can clear it at any time via your browser settings.
TuneLens does not use Google Analytics, Meta Pixel, or any other third-party tracking or advertising cookies. We do not profile users for advertising purposes.
You can control or delete cookies at any time through your browser settings. Deleting the Supabase authentication cookie will sign you out of TuneLens. Most browsers also allow you to block cookies entirely, though this will prevent the app from working.
If we introduce new cookies in the future, we will update this page and, where required by law, seek appropriate consent.
