TsskFlow — Privacy

TsskFlow collects nothing.

Today, TsskFlow — the app on your phone and the program on your Mac — collects nothing. Everything stays on your Mac. Nothing about you or your work is sent to us or stored on our servers: the relay passes sealed messages between your phone and your Mac, cannot open them, and deletes them within minutes.

TsskFlow is a relay between your phone and your Mac. Your messages are end-to-end encrypted: they’re sealed on one device and opened only on the other. We have no key, and neither does our hosting provider.

• No account in the app. No name, no email, no password.
• No content. We don’t collect your code, your prompts, your files, or the commands your agents run.
• Held briefly, then gone. The relay holds a sealed message only until your device picks it up, and deletes it then. Anything not picked up is deleted within 6 minutes.
• Two open connections. While the app is open and the Mac program is running, each keeps one connection to the relay, and the relay holds the two together so a message from one reaches the other at once. While both are open, the relay knows they belong to the same pairing. It still cannot read what passes between them. When you close the app, its connection closes.
• Lock-screen alerts. To wake your phone, we send short fixed phrases (like “Claude Code needs you”) through Apple. Not your content.
• What the network sees. Like any internet service, our hosting provider sees basic traffic information such as IP addresses and timing. We don’t log it.

Who’s involved

Cloudflare runs the relay and serves the Mac program’s downloads. Apple delivers the app and lock-screen alerts. Vercel hosts the website.

The website is hosted by Vercel, which keeps standard request logs (such as IP address and pages visited) for a short time. The app doesn’t use Vercel.

The Mac program is downloaded from Cloudflare, which keeps standard request logs. TsskFlow doesn’t check for updates on its own: you get a new version by running the install command again.

The coding agent you run

TsskFlow puts a coding agent that is already on your Mac — Claude Code, Codex, Copilot, opencode, Antigravity or Grok Build — on your phone. That agent follows its own maker’s terms and privacy policy, and may collect data under your account with them, as it would if you ran it at the Mac yourself. That is outside TsskFlow’s control and not covered by this page.

This may change later

Today, TsskFlow collects nothing. Everything stays on your Mac. In the future, we may collect data to improve and secure TsskFlow. If that ever happens, we’ll update this policy first, and you’ll know.

This website’s signup form

This website has one form, the signup in the footer. If you use it, we keep the email address you choose to give it — and nothing else — with Buttondown, only to tell you when what you asked about is ready. Unsubscribe any time.
