Privacy

Last updated 3 October 2026

The short version: no accounts, no tracking, no analytics, no adverts and no cookies. We only handle what's needed to sell you the game and check your key.

On your device

Formicarium keeps your settings, and once you've unlocked it your licence key, in your browser's own storage on your device. It stays there; we can't see it. Clearing your browser's data deletes it.

Unlocking the game

When you enter your key, the game sends the key and a short device label (for example "Windows · 2026-10-03") through our server to Lemon Squeezy, which confirms the key is real and counts the device towards your 3. About once a week, when you're online, the game quietly checks the key is still valid. Our server passes these checks on and doesn't keep them.

Buying

Payments are handled entirely by Lemon Squeezy, our reseller. It collects your name, email address, payment details and country (for tax), under its own privacy policy. We never see your card details. We can see your order (your name, email address and what you bought) and use it only to deal with your purchase, such as a refund or a problem with your key.

Running the website

Like any website, these pages pass through the companies that deliver them, and they see your IP address to do it: Cloudflare hosts the site, Google Fonts supplies the lettering, and Lemon Squeezy's checkout loads when you choose to buy. We don't receive or keep visitor logs ourselves.

Emailing us

If you write to us, we use your email address only to reply.

Your rights

Under UK data protection law you can ask what we hold about you, and ask us to correct or delete it: email [email protected]. If you're unhappy with how we've handled it, you can complain to the Information Commissioner's Office (ico.org.uk).
