Privacy notice
Updated October 20, 2026
Who answers for your data
acnescartreatment.net runs on its own and chooses what it measures, so it is the party responsible for that data. Questions go to privacy@acnescartreatment.net.
What is collected
- Visit statistics. The pages you open, the page that sent you here, how far you scroll and how long you stay, the links and buttons you press, plus device details like screen size, language setting and time zone.
- Scar matcher answers. These are handled inside your browser and never sent. Only the matched scar type, your skin tone choice and whether you still get breakouts travel along in the analysis link, and only if you press it.
- Server logs. The hosting company records IP addresses, browser type and requested pages to keep the site safe and running.
How the statistics work
Your browser sends visit statistics to this site's own address, /api/trail. From there they go to an analytics provider (EU) that keeps them on servers in the European Union. Your IP address is passed along so a rough location, such as the country, can be worked out. A random code in session storage links the pages of one visit and is deleted when the tab closes, so two visits cannot be tied together. Statistics use no cookies. Visitors in the EU are counted only after they press "Allow".
The analysis link
Buttons such as "Start my analysis" pass through acnescartreatment.net/scar-scan and then open acne.today, a separate paid service. The link tells acne.today which site and which button sent you. Whatever you share there, such as photos, answers or payment details, is covered by acne.today's own privacy policy.
Legal grounds
- Statistics on EU visitors: your consent. Withdraw it any time with "Statistics choice" at the foot of the home page.
- Statistics on other visitors and server logs: a legitimate interest in a secure site that works.
- Emails you send: so we can reply.
What stays in your browser
| Name | What it does | Kept until |
|---|---|---|
| sxStat | Remembers your statistics answer. Local storage; never sent. | You clear it |
| sxDock | Remembers that you closed the bottom bar. Session storage. | The tab closes |
| sx_dv, sx_ss, sx_pg, sx_zn | Random visit code and page count for statistics. Session storage, not cookies. | The tab closes |
How long it is kept
Server logs are deleted within 90 days. Emails are kept only as long as needed to help you, and never longer than two years.
Who gets it
Only the analytics provider and the hosting company, each with only what its job needs. Nothing is ever sold.
Your rights
You may ask to see, fix, delete or take a copy of your data, to limit how it is used, or to object to its use. Write to privacy@acnescartreatment.net and expect a reply within four weeks. You can also complain to the data protection authority where you live.
