Privacy

What leaves your Mac, and what never does.

The short version: nothing you read, ask or download leaves your Mac. We keep what an order needs and no more.

What the app sends

The app connects to our servers for three things and nothing else:

• Content updates. It asks for the library catalogue and downloads the books, maps and models you choose.
• App updates. It checks for a new version of the app through Sparkle and tells you when there is one.
• Licence status. When you activate a plan, and now and then afterwards, it sends your licence key, a device identifier, the Mac's name and the app version, so the service knows which Macs are on the plan.

It sends no telemetry. What you read, what you ask the assistant, what you search for and what you download stay on your Mac. The assistant runs on your Mac, so no question goes to any server.

What we store when you buy

• The email address on your order, so we can find your plan and send your key again.
• A hash of your licence key, not the key itself.
• Which plan you have and when it ends.
• For each activated Mac, the name it reports and the time it was activated.

Payment is handled by Stripe. Card numbers go to Stripe and never to us. Stripe's own privacy policy covers what Stripe keeps. We see the email, the amount, the plan and the Stripe identifiers of the order.

If you join the waitlist, we store the email you enter and the plan you picked, and use them only for the message the form describes.

Hosting

The site, the content service and the licence service run on Cloudflare. Cloudflare keeps standard request logs (IP address, time, what was requested) for a short period as part of serving and protecting the site. We run no analytics on the site and set no cookies of our own. Stripe sets its own cookies on the checkout page.

Your rights

You can ask for a copy of what we hold about you, ask us to correct it, or ask us to delete it. If we delete an order, its key can no longer activate new Macs. What you have downloaded keeps working. We keep order records while the plan is active and for as long afterwards as tax law requires. Ask by replying to your Stripe receipt, or see the support page. If you are not happy with how we handle your data, you can complain to the UK Information Commissioner's Office.
