Message Storage, Privacy & Security
E2EE messages are encrypted when you click Send and only decrypted when they reach the receiver's device.
Encrypted messages are stored on the devices they are created/received on so you can read them offline. They are also stored online so you can use different devices.
This gets your location and pins it on a button-link to Google Maps that can be sent in a message. It's a one-time-per-click operation which cannot track you further.
Chats, images and files that you save to your downloads folder are not encrypted and fall outside of E2EE's security scope.
