Privacy policy
Last updated: October 20, 2026
Who is responsible
whatishormonalacne.com is run as an independent website, and the site itself is responsible for the data on this page. Questions about your data go to privacy@whatishormonalacne.com.
What we collect
- Visit statistics: the pages you view, the address that sent you here, how long you stay, how far down you scroll, which buttons and links you tap, and general device details such as screen size, language setting and time zone.
- Life stage picks: when you choose a life stage on the home page, only the button you tap later is counted. The choice itself stays in your browser.
- Server logs: the hosting provider records IP addresses, browser types and requested pages to keep the site secure and working.
How the statistics travel
Your browser sends visit statistics to /api/glow, an endpoint on this site. That endpoint passes them to an analytics provider (EU), which keeps them on servers in the European Union. Your IP address goes along so a rough country can be worked out. A random code in session storage links the pages of a single visit and is wiped when you close the tab, so two visits can't be tied together. No statistics cookies are used. If you are in the EU, nothing is counted until you press "Allow".
The skin analysis link
Buttons such as "Start my analysis" pass through whatishormonalacne.com/hormone-scan and then open acne.today, a separate paid service. The link tells acne.today which page and which button you used, and the life stage you picked if you picked one. Photos, answers and payments you give acne.today fall under its own privacy policy.
Why we are allowed to
- Statistics for EU visitors: your consent. You can change your answer any time with "Statistics choice" at the foot of the home page.
- Statistics for visitors outside the EU and server logs: our legitimate interest in a secure, working site.
- Emails: we need them to reply to you.
Stored in your browser
| Name | What it does | How long |
|---|---|---|
| whOk | Your statistics answer. Local storage, never sent anywhere. | Until you clear it |
| whLook | Light or dark look, if you switch it. Local storage. | Until you clear it |
| whBar | Remembers that you closed the bottom bar. Session storage. | Until the tab closes |
| wh_v, wh_s, wh_n, wh_z | Random visit code and page count for statistics. Session storage, not a cookie. | Until the tab closes |
How long data is kept
Server logs for at most 90 days. Emails for as long as we need to help you, and no longer than two years.
Who receives data
Only the analytics provider and the hosting provider, each with just what it needs for its job. We never sell data.
Your rights
You can ask to see your data, fix it, delete it, get a copy, restrict its use or object to it. Email privacy@whatishormonalacne.com and you will hear back within four weeks. You can also complain to the Dutch Data Protection Authority (Autoriteit Persoonsgegevens) or to the data protection authority where you live.
