Searching saves nothing. No project, no history, no record of the username. Saving is always an explicit action.
Saving
After a search, use Save research locally. Give it a title, and choose whether to store the loaded records.
Record storage is off by default. Without it, the query and your notes are saved — enough to repeat the search later without keeping a copy of someone's content in your browser indefinitely.
Where it goes
IndexedDB, in this browser. There is no account and no upload. Clearing your browser data deletes it, and there is no copy anywhere to restore from.
Recent searches
Off by default. If you turn it on in the privacy center, queries are stored locally and can be cleared at any time. They are never included in a workspace export.
