Privacy
Last updated: October 19, 2026
Who is responsible
acneonchin.com runs as a site of its own and is responsible for the personal data this page describes. Questions go to privacy@acneonchin.com.
What gets recorded
- Visit statistics: which pages you open, the page that sent you here, how long and how far you read, which links and buttons you press, and device basics such as screen size, language setting and time zone.
- Your chin check answers: the result is worked out in your own browser and is not sent to us.
- Server logs: the hosting service logs IP addresses, browser types and requested addresses to keep the site safe and running.
How visit statistics work
Your browser sends visit statistics to this site's own address, /api/touch, and from there they pass to an analytics provider (EU) that stores them on servers inside the European Union. Your IP address is passed along so a rough location (country and city) can be worked out. A random code kept in session storage links the pages of one visit and disappears when you close the tab, so separate visits are not tied together. No statistics cookies are set. Visitors in the EU are only counted after they choose "Allow".
Where the analysis button goes
"Start my analysis" and similar buttons pass through acneonchin.com/chin-scan and then open acne.today, a separate paid service. The link tells acne.today which site and which button you came from, and which result the chin check gave if you used it. Anything you share with acne.today, such as photos, answers or payment details, falls under its own privacy policy.
Legal grounds
- Statistics about EU visitors: your consent, which you can change at any time with "Statistics choice" at the bottom of the home page.
- Statistics about other visitors and server logs: our legitimate interest in a safe site that works well.
- Emails you send: handling your question.
What your browser keeps
| Name | Purpose | How long |
|---|---|---|
| cnOk | Remembers your answer to the statistics question. Local storage, never sent. | Until you clear it |
| cnTheme | Remembers light or dark mode if you switch it. Local storage. | Until you clear it |
| cnBar | Remembers that you closed the bar at the bottom of the screen. Session storage. | Until the tab closes |
| _j_d, _j_s, _j_n, _j_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: no longer than 90 days. Emails: as long as needed to answer you, and no more than two years.
Who receives data
Only the analytics provider and the hosting service, each with no more than it needs. Data is never sold.
Your rights
You can ask to see, correct, delete or take a copy of your data, ask us to limit its use, or object to it. Write to privacy@acneonchin.com and you will get an answer within four weeks. You can also complain to the Autoriteit Persoonsgegevens (the Dutch data protection authority) or the regulator where you live.
