Permission Expiry Guard

Make macOS app permissions expire automatically like share links

Problem

Mac users feel uneasy when apps keep microphone, camera, and other permissions forever after a single grant. A tool that lets permissions expire on a schedule shows people want temporary, revocable access. Most users also don’t want a heavy security suite, just a lightweight switch.

Solution

A menu bar utility that lets users set expiry times for each app’s permissions (15 minutes, 1 hour, tonight, when the app quits) and auto-revokes them with a notification. It groups permissions by app and cleans up records left by deleted apps. Everything uses native system mechanisms and can be restored with one click.

Users

Privacy-conscious Mac users, especially those who try new apps or install temporary software often.

MVP

List apps and their permissions; set expiry time and condition per permission; auto-revoke with notification; group expired records by app; clean up leftover permissions from deleted apps; quick actions from the menu bar.

Revenue

One-time purchase at $14.9, or $2.9/month with multi-device sync and advanced cleanup rules.

Why now

macOS permission management has long been weak, users are more privacy-aware, and big companies won’t build granular temporary grants. Indie developers can ship a tool with system APIs and monetize via one-time purchase.
