Privacy

What we collect

When you sign up to read the free chapters: your email address, the date you signed up, which page you signed up on, and that you ticked the box agreeing to hear from us. When you buy the handbook, Gumroad shares your email address and licence key with us so we can unlock it.

The site sets two cookies that keep you signed in on that browser for a year: one for the free chapters and one for the full handbook. They are not used for advertising or tracking. Your reading progress and checklists are saved only in your own browser.

How we use it

We use your email only to send you The Brown Gene emails you agreed to, such as the free chapters, new chapters and occasional updates. Every email says who it is from and has an unsubscribe link, and we act on unsubscribes within five working days. We never sell, rent or share your details for anyone else's marketing.

Where it is stored

Sign-up records are stored with Cloudflare, which hosts this site, and payments are handled by Gumroad. Both may store data outside Australia. We never see your card details.

Your choices

You can ask to see, correct or delete your details at any time by emailing hello@thebrowngene.com. If you are not happy with how we handled a privacy concern, you can contact the Office of the Australian Information Commissioner at oaic.gov.au.
