Privacy — Birthday Atlas

Not yet reviewed by a lawyer. The facts below are accurate to what the software does. A postal address will be added here when we begin sending marketing email, which we do not do today. Nothing here is legal advice.

The short version

Reading your book sends us nothing. The birthday you type is processed entirely in your browser, and it lives in the part of the web address — the fragment, after the # — that browsers never transmit to a server. We do not set cookies. We do not use advertising or tracking pixels. We do not sell or share personal information.

What we collect when you read

Your birthday: not collected. It is never sent to us, never stored by us, and never appears in our logs.

Ordinary server logs. Like any website, our host records standard request information — IP address, browser and device type, the page requested, and the time. These are used to keep the site running and secure, and are retained for 30 days.

Aggregate analytics. We use Cloudflare Web Analytics, which counts page views and how readers arrive. It sets no cookies, stores nothing on your device, and does not fingerprint or build a profile of you.

It does not receive your birthday. The date lives in the part of the address after the #, and that part is not included in what the analytics script reports — it sends the page path only. We checked this by loading a book and reading what actually left the browser, rather than taking it on trust.

Fonts. Typefaces are served from this site, not from Google Fonts or any other font service. The analytics script is the only thing your browser fetches from anyone but us.

If you give us your email

Email is always optional and never required to read your book. There is one place to give us an address — the poster waitlist on the last page — and it asks for the address and nothing else.

We do not collect your birthday with it. The waitlist form sends us your email address on its own; the date stays in your browser, where the rest of the site keeps it. We store the address, and the date you joined.

Who else handles it. The list is stored with Resend, an email service that holds it on our behalf and does not use it for anything of their own. They are the only company that receives anything you give us.

Children

Birthday Atlas is not directed to children. We do not knowingly collect information from anyone under 16, and birthdays after 2010 are not issued a book.

Your choices

Depending on where you live, you may have the right to know what personal information we hold about you, to get a copy, to correct it, or to have it deleted. Write to us at hello@birthdayatlas.com and we will act on it. We do not sell or share personal information, and we do not use it for targeted advertising.

Changes

If this policy changes we will update the date at the top. Material changes affecting people on our email list will be sent to that list.
