Privacy issue: messages I delete might be partially redisplayed if the respondent quotes them #5595

CaiusJard commented 1 year ago

If I send some sensitive info then delete the message, I find that the respondent might quote it when they reply. This causes the first few words of it to reappear in my inbox. I'd like a setting to turn this off, so that it just says "original message not found" with their reply under it rather than "hey Jim your password reset token is 1234, you can use it... original message not found"

Hi @CaiusJard

Quoted replies are a convenience feature you can think of as similar to copy/pasting message text into a new message and sending. As a copy/paste of the original message, the lifetime of the quote is decided by the lifetime of the new message. You cannot quote a message after it has already disappeared or been deleted, and you can’t tap back to an original message from the quote if it has disappeared or been deleted.

"you can’t tap back to an original message from the quote if it has disappeared or been deleted."

and that's the bit where this setting can hook into. Signal clearly knows the original message hs been deleted, so a setting to not render the quote on that case would be welcome
