My chats are gone
"The browser deleted KUVRT's data here" or "The browser lost KUVRT's data here" means the browser cleared or damaged what KUVRT kept on this device. If you use KUVRT on another device, your chats are still there.
Tap "Link with another device" to get your chats back from another of yours. "Restore from recovery phrase" brings back your KUVRT and contacts only, and cuts off your other devices until you link them again.
"Linking did not finish" means KUVRT closed while your chats were being copied. Your other device takes this one off its list. Tap "Link again". If it says to update your other device, open KUVRT there and tap "Update now" if it asks, then link again. If it says linking ran out of time, keep KUVRT open in front on both devices and start again.
