Privacy
Last updated: October 19, 2026
Who runs this site
teenacnetreatment.com is run as a standalone site and is responsible for the personal data described here. Questions about your data go to privacy@teenacnetreatment.com.
What gets recorded
- Visit statistics: which pages you open, the page that sent you here, time on the page, how far you scroll, which links and buttons you press, and basic device details such as screen size, language and time zone.
- Your answer in the treatment timeline: it is handled in your browser only and is never sent to us.
- Server logs: our hosting provider keeps IP addresses, browser types and requested addresses to protect the site and keep it running.
How visits are counted
Your browser sends visit statistics to our own address, /api/open, which passes them on to an analytics provider (EU) that stores them inside the European Union. Your IP address is passed along so a rough location such as country or city can be worked out. A random code in session storage ties the pages of one visit together and disappears when you close the tab, so separate visits can't be linked. No statistics cookies are set. Visitors in the EU are only counted after they press "Allow".
Where the analysis button goes
Buttons such as "Start my analysis" go through teenacnetreatment.com/teen-scan to acne.today, a separate paid service. The link tells acne.today which site and which button you came from. Anything you share there, such as photos, answers or payment details, falls under acne.today's own privacy policy. Under-18s should use it together with a parent.
Legal grounds
- Statistics about visitors in the EU: your consent, which you can change at any time through "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: answering your question.
What your browser keeps
| Name | Purpose | How long |
|---|---|---|
| teStat | Your answer to the statistics question. Local storage, never sent. | Until you clear it |
| teLook | Light or dark display, if you pick one. Local storage. | Until you clear it |
| teBar | Remembers that you closed the bar at the bottom. Session storage. | Until the tab closes |
| _y_d, _y_s, _y_n, _y_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 more than 90 days. Emails: as long as it takes to help you, and two years at most.
Who else sees it
Only the analytics provider and our hosting provider, each limited to what 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@teenacnetreatment.com and you will get an answer within four weeks. You may also complain to the data protection authority where you live.
