I wonder why Apple doesn't 'just' delete the notification data associated with the app from the internal database when the user deletes the app? It seems like asking for problems to just keep old notification content around forever.
On which end, Apple or Signal? Because neither Apple nor Google will overhaul this behavior, the FBI asked for it directly: https://arstechnica.com/tech-policy/2023/12/apple-admits-to-...

> Apple has since confirmed in a statement provided to Ars that the US federal government “prohibited” the company “from sharing any information,” but now that Wyden has outed the feds, Apple has updated its transparency reporting and will “detail these kinds of requests” in a separate section on push notifications in its next report. Ars verified that Apple’s law enforcement guidelines now notes that push notification records “may be obtained with a subpoena or greater legal process.”
I don't read it that way. But I suppose we'll never know. Or if we find out, it'll be in around fifty years.
I'm not sure precisely how the NAND controller responds to requests for raw data from blocks with "deleted" data. And if this would require decapping the flash.
Some flash will happily let you see the data and delay erasing it.
Generally flash is non deterministic about when blocks even those with entirely stale data are erased . It might be years before the block is reused due to wear leveling algorithms and it might retain data that entire time.
Here's hoping the controller for phones which hold sensitive data are more active
