Privacy
Updated October 18, 2026
Who runs this site
hormonalacne.net is run as a standalone site, and we settle how any visitor data gets used. Questions go to privacy@hormonalacne.net.
What we learn about your visit
- Page statistics: the page you open, the page or search engine that sent you, how far you scroll, how long you stay, the buttons and links you use, and basic facts about your device such as screen size, browser language and time zone.
- The pattern check: the boxes you tick are handled in your own browser. They are never sent to us or stored.
- Hosting logs: your IP address, browser type and the files you request, kept by our hosting company to keep the site safe and online.
How the statistics work
Your browser sends page statistics to our own address, /api/view. From there they go to an analytics provider (EU) that stores them in the European Union. Your IP address is passed along so the provider can estimate your country and city. A random visit number sits in your tab's session storage so we can see which pages belong to one visit; it disappears when you close the tab, and we never connect it to a later visit. No cookies are set for statistics. Visitors from the European Union are only counted after they choose "Allow" in the notice on the page.
The analysis button
"Start my analysis" and similar links pass through hormonalacne.net/my-skin and then open acne.today, a separate paid service. The link tells acne.today that you came from this site and which button you pressed. Anything you do on acne.today, such as uploading a photo or paying, is covered by acne.today's own privacy policy, not this one.
Why we may do this
- Statistics for EU visitors: your consent, which you can withdraw at any time with "Statistics choice" at the bottom of the page.
- Statistics for visitors elsewhere, and running a secure site: our legitimate interest in a working site and knowing which pages help.
- Replies to your emails: the steps you ask us to take.
What your browser keeps
| Name | What it does | Kept for |
|---|---|---|
| haStats | Your statistics choice. Local storage, never sent to us. | Until you clear it |
| haDock | Remembers that you closed the bar at the bottom of the screen. Session storage. | Until the tab closes |
| _h_d, _h_s, _h_n, _h_z | The random visit number and page count for statistics. Session storage, not a cookie. | Until the tab closes |
Retention and sharing
Hosting logs are deleted within 90 days. Emails are kept as long as your question needs, and never longer than two years. Data goes only to the analytics provider and the hosting company, as far as they need it. We do not sell data.
Your rights
You may ask to see, correct or delete your data, to limit its use, to take it with you, or object to its use. Email privacy@hormonalacne.net and you will hear back within four weeks. You can also complain to the Dutch Data Protection Authority (Autoriteit Persoonsgegevens) or to the authority in your own country.
