Privacy policy

Last updated November 2026.

This policy covers attentiongym.io, run by Ultra Operations LLC, a Washington limited liability company ("we"). The site is intended for adults in the United States.

Children and teens

Some of our books are written for kids and teens, but this website, our mailing list and our shop are for adults 18 and over. We don't knowingly collect personal information from or about anyone under 18. The books themselves are paper and collect nothing, and we never ask for a child's name, age, school or email address.

If you think a child has given us information, email hello@attentiongym.io and we'll delete it. If we find out on our own, we'll delete it too.

What we collect

If you join the mailing list: your email address, which book you're interested in, the page you signed up on, and the date. We ask you to confirm you're 18 or older, but we don't store your age.

If you buy a PDF: Stripe collects your email address, name, payment details and billing address, which is also used to work out sales tax. Stripe may ask for a phone number if you choose to save your details for faster checkout. If you choose another option at checkout, such as Cash App Pay, Klarna, Amazon Pay or crypto, that provider handles your payment too. We can see the order record in Stripe (including your email, what you bought, the amount, any sales tax and the date), but we never see or store your full card number or payment account details.

When you visit: our hosting provider keeps routine server logs, such as IP address, browser type and pages requested. Our pages load fonts from Google, which receives your IP address when that happens. When you start a checkout, we use your IP address to work out your country, because we only sell PDFs in the US. We don't store that check.

We don't use analytics tools, advertising cookies or tracking pixels, and our own pages don't set cookies. Stripe may use its own cookies on its checkout pages.

How we use it

We use this information to send the emails you asked for, deliver your files, help with orders, keep the site running and secure, and meet our legal and tax obligations.

Who we share it with

We never sell or rent your information, and we don't share it for advertising. We share it only with the services that run the site and only for the purposes above: Stripe and the payment option you choose at checkout (payments), Supabase (mailing list database and file storage), Vercel (hosting) and Google Fonts (fonts). If we start using an email delivery service, it will receive your address to send our emails. We may also disclose information if the law requires it.

Health data

The Attention Gym is an educational practice series, not a health service. We don't ask for or collect health information, so please don't send us any about yourself or your family.

How long we keep it

Mailing list details stay until you unsubscribe or ask us to delete them. Order records are kept for as long as we need them for tax, accounting and legal reasons.

Your choices

Every marketing email has a one-click unsubscribe link. To see, correct or delete the information we hold about you, email hello@attentiongym.io and we'll respond within 30 days. We may need to keep order records the law requires, and we won't treat you differently for asking.

Do Not Track

We don't track visitors across other websites, so browser Do Not Track signals don't change how the site works.

Security

Our mailing list database and PDF files are not publicly accessible, and connections to the site are encrypted. No system is perfectly secure, so we can't guarantee absolute security.

Other sites

Paperback links go to Amazon, and social links go to those platforms. Their own privacy policies apply once you're there, as Stripe's and your chosen payment provider's do for payments.

Changes to this policy

If we change this policy, we'll update the date at the top. If a change affects how we use information we already hold, we'll tell you by email where we can.
