Privacy

Last updated 24 August 2026

Airlock is a paid application, not an advertising-funded one, and it is built so that being paid does not require watching you. This page says exactly what leaves your Mac, because a policy that only says what does not is worth very little.

What stays on your Mac

All of it. Specifically:

There is no account and no sign-in, so there is no server that could hold any of this even if we wanted it to.

What leaves your Mac

Four requests. This is the complete list.

1. Activating your licence

Once, when you paste your licence key: Airlock sends the key and this Mac's hardware identifier to our licence server, which registers the licence to that Mac with Lemon Squeezy and sends back a signed licence. It does not happen again unless you activate on a different Mac.

2. Checking your subscription

In the days around your renewal date, Airlock asks our licence server whether your subscription is still active, and receives a new licence valid for the next period.

3. Checking for updates

Airlock can update itself using Sparkle, a widely used open-source updater. This is off until you turn it on: Airlock asks before its first check and does nothing if you decline. When enabled, it requests an update feed from our host. No identifier is attached.

4. Album art

When the media card is showing something Spotify is playing, Airlock loads the cover image from the address Spotify gives it — a request to Spotify's image servers, not to us. It carries nothing about your licence, though those servers necessarily see your IP address as with any image on the internet. Switch the media widget off in Settings and it never happens.

Buying a subscription

Payments are handled by Lemon Squeezy, who act as merchant of record. You buy from them, not from us, and your payment details go to them and never to us or to your Mac — we never see or store a card number.

From them we receive your email address, your licence key, and your subscription status, which is what lets us issue and renew your licence and answer you if you write in. Lemon Squeezy handle billing data under their own privacy policy.

This website

No analytics, no cookies, no tracking pixels, and nothing third-party of any kind: the one webfont is served from this site rather than from Google, and the one script is ours and only works the approval demo on the front page. Nothing is set in your browser. Our host keeps standard short-lived server logs for security and reliability, as any host does.

Who processes data on our behalf

That is the entire list. No analytics provider, no CRM, no email marketing platform.

How long anything is kept

Subscription records are kept while your subscription is active and afterwards only as long as tax and accounting law requires. Server logs are short-lived and are not used to build any profile.

Your rights

If you are in the EU or UK, you have the right to access, correct, export or delete your personal data, to object to processing, and to complain to your data protection authority. Write to hello@useairlock.app and we will act on it.

Deleting your data means cancelling your subscription and removing the record of it. Your copy of Airlock keeps working until the period you paid for ends, because the licence on your Mac is self-contained.

Children

Airlock is a Mac utility for professional use and is not directed at children under 16.

Changes

If this policy changes in a way that affects what leaves your Mac, that change will be in the release notes of the version that makes it — not quietly published here. Adding a new outbound request without saying so would break the only promise on this page that matters.

Who we are
