TestFlight (beta)

Clessira is currently in public beta — free, with all features.

1. Open the TestFlight invite link from clessira.app.
2. Install the TestFlight app if you don’t have it.
3. Tap “Join”, then “Install”.

After release, Clessira will be available in the Mac App Store as a one-time purchase, not a subscription.

First launch

Clessira doesn’t announce itself loudly: it appears in the menu bar and shows a small welcome wizard.

Permissions the app may request:

• Notifications — so the tracking prompt can appear as a macOS notification when the app is in the background.
• Launch at login — optional, so Clessira is available right after your Mac logs in.

What the app does not request: full disk access, screen recording, input monitoring. Clessira knows nothing about what you do — only what you tell it.

Continue to First run.
