Hush analyses audio entirely on your own machine. Nothing is uploaded, no audio is sent anywhere, and there is no cloud processing step. This is not a policy that could quietly change — it is how the software is built. Hush works with no internet connection at all.
There is no analytics or telemetry
Hush does not track how you use it, does not report crashes automatically, and contains no analytics of any kind. The only network request it ever makes is to check your licence.
What the licence check sends
When you activate or re‑check a licence, Hush sends to the store:
- your licence key
- a machine identifier — a one‑way SHA‑256 hash of your computer’s hostname, your username and your operating system. It cannot be reversed into any of those. Its only purpose is to let the store count how many machines a licence is used on, and to let Remove from this Mac free that slot again.
That request goes to Lemon Squeezy, who process the payment and issue the licence. Their privacy policy covers what they hold, and it is where your name, email and payment details live. Hush never sees your payment information, and neither does its developer.
What is stored on your computer
Your licence key and the date it was last verified are saved in a small file in your user Library folder, so Hush does not have to ask the store every time you open it. Removing the licence deletes it.
If you email support, that email is kept only as long as needed to help you. It is not added to a mailing list.

This describes how Hush actually behaves, and every claim above is verifiable in the software rather than being a promise about intent. It is written plainly rather than in legal language, and it is not legal advice — if you need a policy that satisfies a specific regulator, that is a question for a solicitor.
