The extension runs on Vision Pro itself
SELFLEX uses the Safari web extension support introduced in visionOS 26.2. Time is not relayed from another device — it is measured in the window you are looking at, as it happens, on this device.
SELFLEX measures the time you spend in Safari directly on Apple Vision Pro. The extension runs here, the records stay here, and the dashboard opens without squeezing your numbers onto a small display.

Earlier releases only displayed the summary arriving from other devices. Since 1.4.8 the extension runs on Vision Pro too, so the device produces its own data.

None. There is no SELFLEX account and no sign-up. Your own Apple Account only comes into play if you want records merged across devices.

Free. No ads, no analytics server, no in-app purchases.
An empty summary on first launch means the extension is not enabled yet: open Settings → Apps → Safari → Extensions and turn on SELFLEX. Alternatively, enabling “Visit records” sync on your iPhone, iPad or Mac brings their summary in even if you have never browsed on Vision Pro.
SELFLEX has no server, no user database and no analytics stack. Time measured on Vision Pro follows the same rule.
