This is the principle the whole privacy story hangs off: recordings are local-first.

On your filesystem

Each recording is a folder in ~/Documents/ScreenSolo Sessions/ (macOS) or %USERPROFILE%\Documents\ScreenSolo Sessions\ (Windows). Inside each session folder:

  • session.mp4 — the video
  • metadata.json — duration, start time, device model
  • keyframes/*.png — the per-keyframe screenshots
  • annotations.json — any drawings, spotlights, or AI write-ups you added

You can back these up, sync them to your own iCloud Drive / Dropbox / wherever, or delete them. They're yours.

When something leaves your device

There's exactly one point where session data leaves your filesystem:

  • AI features — when you call Smart Extract, Explain, an AI keyframe write-up, or Session Summary, the *specific frame(s) or text* you asked about is sent to Claude (via our backend, which proxies for token billing). Claude's response comes back. Anthropic doesn't store or train on the data, and the desktop caches the response locally.

Exporting a file (video, PDF, or slide deck) writes it to your own device — nothing is uploaded.

What we never see

  • The other sessions in your folder
  • Your filesystem outside the session folders
  • Your iMessage / email / browsing history / anything outside ScreenSolo

Cloud sync (planned, not shipped)

We're considering an opt-in "sync recordings across devices" feature for a future release. If we ship it, you'd opt in explicitly per session, and the privacy policy would be updated to spell out the new data flow. As of 2026, it's not shipped — every recording stays on the device that captured it.
