Quiz answers
Your answers are saved in your browser's local storage so you can return to your results. They are not sent to a server and we cannot see them. Clearing your browser data removes them. If you copy your results link, your answers are encoded into that URL, so treat the link as personal.
Photos
If you use the optional photo feature, the image is checked for brightness, focus and size entirely inside your browser. It is only transmitted when you press the analyze button. At that point it is sent to Anthropic's API for analysis and returned. It is not written to disk, not added to a database, and not used to train anything. There is no account attached to it. If you never press analyze, the photo never leaves your device.
Analytics
We use privacy conscious analytics to understand which pages are useful. This records aggregate information such as page views, referring site, country and device type. It is not used to identify you individually.
Affiliate links and cookies
When you click a link to a retailer, that retailer may set a cookie to attribute the visit to us so we can be paid a commission. This is standard affiliate tracking and is controlled by the retailer, not by us. Their privacy policy applies once you are on their site. See how we make money.
What we do not do
- We do not sell or rent personal information.
- We do not require an account, an email address, or a name to use the site.
- We do not build advertising profiles about you.
Your rights
Depending on where you live, you may have the right to access, correct or delete personal information we hold, and to opt out of its sale or sharing. Because we do not hold accounts, in most cases there is nothing for us to delete. If you have subscribed to email updates, every message contains an unsubscribe link, and you can ask us to remove you at any time via the contact page.
Children
This site is not directed at children under 13 and we do not knowingly collect information from them. The hair quiz includes an option for a parent shopping for a child, which collects nothing about the child beyond hair characteristics used to generate the routine.
Changes
If this policy changes materially we will update the date at the top of this page.
