## What it means

The endpoints and key-management design define the protection. The service can still process metadata, and a compromised endpoint can reveal plaintext.

## For hosting

Do not transfer a product’s encryption claim to every feature. Review backups, recovery, file sharing and unencrypted rooms or channels separately.

## What happens when a device is lost?

Review verification, key backup and recovery behaviour. Content confidentiality and account recovery can depend on different keys and different trust decisions.
