Does NotchStar work offline and what is the weekly check

NotchStar works offline. After you activate, a licensed copy asks the license server whether the key is still valid when the app starts, if a week has passed since the last check. If you are offline, or the server has a problem, nothing changes and the app keeps working.

The three rules

  1. Your data is never deleted or hidden because of licensing.
  2. Being offline never revokes a license. Only an explicit “not valid” from the license server can.
  3. The check happens at most once a week, when the app starts, and is silent.

What the weekly check sends

It sends your license key and the instance ID that activation returned to Dodo Payments. It does not send your clipboard, notes or files. During the free trial there is no license check, because there is no key to check.

When a license stops working

If the server says the key is no longer valid, for example after a refund, NotchStar shows “This license is no longer active.” You can email for help.

What needs internet

  • Activating a key.
  • Deactivating a Mac, to free its slot at the server.
  • The weekly check, which skips quietly.
  • Anonymous version info, only if you turned it on.

Everything else runs on your Mac. The System Stats tool reads the machine locally. For the full list, read what NotchStar sends.
