The developer and Google are quietly avoiding the issue: they are fully aware of the question, yet they still refuse to respond. All evidence is documented here: https://discuss.ai.google.dev/t/noyb-has-contacted-me-google...

I found that Google AI Studio’s “Delete” button does not delete the server‑side chat.

I tested it by deleting a prompt, deleting the JSON file from Drive, and emptying the Trash. The file was fully gone.

Then I used Google’s official recovery tool.

The JSON came back — and the model instantly continued the conversation with full context.

This is only possible if the server‑side session and conversation were never deleted.

I recorded the entire process in 3 videos:

I also posted this finding under two official Google videos featuring Guillaume Vernade, so Google is aware of it: – https://www.youtube.com/watch?v=BcWFc3H7Khg – https://www.youtube.com/watch?v=LBQfNbPCxQw
