This QR verifies a public-key bundle; it does not contain your full keys or private keys. Compare it in person or over another trusted channel. A screenshot sent alongside the keys in the same chat is not independent verification. The in-app scanner is not enabled yet.
Keys are specific to this browser/device. LINE and your external browser may use separate storage. Clearing browser data loses your keys unless you keep an encrypted backup. Unlocked keys are held in memory; automatic lock occurs after five minutes of inactivity.
