What SlackVault does today, and what it does not

Messages, channels, members and file records go to your own Firebase project. Supabase is not supported yet.

Files do not go to your Google Drive or your Firebase project. When file copying is switched on in our extension build, each file uploads to our file storage with its visibility set to public: the link is hard to guess, but anyone holding it can open the file without signing in. Where no storage key is set in the build, no copy is made, and your archive keeps the file’s details and Slack’s link, which works only while Slack serves that file.

There is no way yet to send records back into Slack.

The sync runs in a browser extension, every 15 minutes, only while that browser is running.

SlackVault can copy only what Slack’s API still returns, so anything older than your plan’s window is out of reach unless an earlier sync already saved it.

If saving one thread fails, the sync logs it and moves on without retrying those replies.

Search checks the most recent page of messages, up to 50 per query, not the whole archive.

The extension and the Android app have no store listing yet, and the source code is in a private repository.
