Short version: we see nothing

Privacy

Stash has no servers and no analytics. Your posts and tips stay in your iCloud, on your Mac and in your git repo.

What Stash stores, and where

On your iPhone and in your private iCloud (CloudKit): the links you share, the public preview (title, creator, cover), your notes and screenshots, and each item's processing status and resulting tip summary.
On your Mac: your library (~/Stash, a git repository) and small settings files in ~/.stash.
Optionally on GitHub: if you add a private remote, your library is pushed there by the Mac app.

What leaves your devices

Claude Code processes posts on your Mac with your own Anthropic account, under Anthropic's terms.
Public previews are fetched from the platform (for example TikTok's oEmbed) when you share.
"Read the whole post" (off by default) uses yt-dlp to fetch the post's captions, comments and, if needed, the video. Media is processed on your Mac and deleted right away. Speech recognition runs on your Mac.

What we collect

Nothing. Stash has no backend, no account, no analytics and no crash reporting.

Deleting your data

"Empty your stash" in the iPhone app deletes everything in iCloud. On the Mac, the menu has the same option for your library, which is a git commit you can undo.
