Interrupt Stack — Privacy Policy

Effective July 2, 2026

The short version: everything you type into Interrupt Stack stays on your Mac. We can't read it, we don't collect it, and there's nothing to leak, sell, or subpoena.

What Interrupt Stack stores

Your parked cards — what you were doing, your next step, your optional note, the name of the app you were in, and timestamps — are saved in a file on your Mac, inside the app's own folder in Application Support. That's it. That file never leaves your machine.

What Interrupt Stack does not do

No analytics or telemetry of any kind
No accounts, no sign-in, no cloud sync
No network connections — the app works identically with Wi-Fi off
No reading of your screen, window contents, browser tabs, or documents — it captures only the name of the frontmost app when you park

Permissions

Interrupt Stack asks for exactly one optional permission: notifications, and only if you turn on the "remind me about parked contexts" setting. It's off by default.

Deleting your data

Use "Clear history" in the app's settings, or delete the app and its container folder (~/Library/Containers/com.tilmann.InterruptStack) — the data is gone, because it only ever existed there.

Purchases

Purchases are processed by our store provider (Gumroad), which handles payment details under its own privacy policy. We receive your email address from them to deliver the app and support you; we don't use it for anything else.

Changes and contact

If this policy ever changes, the current version will always be at this address. Questions: matt@apparentsolopreneur.com
