Hard refresh

This will erase:

App cache and service worker (re-downloaded on reload)
Profile name, paired robots, settings
User scripts (the code in the Scripts editor)
Saved passwords, SSH keys, trust store
Auth tokens (you'll need to sign in again)

Bluetooth pairing is controlled by the browser, not this app. If a robot won't reconnect after the refresh, revoke it at chrome://bluetooth-internals/#devices and re-pair.

Install on iPhone / iPad
Tap the Share button in Safari, then Add to Home Screen.
(Web Bluetooth isn't on iOS — the phone companion at phone.html is the useful install target for iOS.)
