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. If you never press analyze, the photo never leaves your device. If you choose to give an email address anywhere on the site it is passed to MailerLite, who run our mailing list, and is never linked to a photo.
HEIC conversion
iPhones save photos in HEIC, a format browsers cannot display. If you upload one, a conversion library is loaded from a public code CDN and the photo is converted to JPEG inside your browser. The image itself is not uploaded anywhere during that step. The CDN sees a request for the library file, as it would for any script, and nothing about your photo.
Analytics and cookies
We use Google Tag Manager, which loads Google Analytics, to understand which pages are useful and where visitors come from. This records information such as pages viewed, the site that referred you, approximate country, and device type. These tools set cookies in your browser.
We record four things you do on the site, so we can tell which parts are worth improving: completing a quiz, subscribing to email, clicking through to a retailer, and running a photo analysis. These are recorded as anonymous events. They are not linked to a name, an email address, or an account, because the site does not have accounts.
If we run advertising, Google may also use these cookies to measure whether an advert led to a visit, and to show our adverts to people who have visited before. You can opt out of personalised Google advertising at adssettings.google.com, and browser settings or an extension can block these cookies entirely. The site works normally without them.
Your cookie choice
The first time you visit you are asked whether to allow analytics and advertising cookies. In the EU, the UK and Switzerland nothing is loaded until you say yes. Elsewhere they start enabled, in line with local law, and rejecting takes effect straight away.
You can change your mind at any time using the Cookie settings link in the footer of any page. Your choice is stored in your own browser and nowhere else, so clearing your browser data resets it.
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 or a name, and no part of the site requires an email address. Giving one is entirely optional.
- 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.
