Privacy notice
Last updated: October 19, 2026
Who runs this site
acnespottreatment.org is a stand-alone site and acts as the controller for the personal data described here. Questions go to privacy@acnespottreatment.org.
What we collect
- Visit statistics: pages viewed, the referring page, time spent, scroll depth, clicks on links and buttons, and basic device facts such as screen size, browser language and time zone.
- Your choice in the spot matcher: handled entirely in your browser. It is only passed on as the spot type inside the analysis link, and only if you click that link.
- Hosting logs: our host keeps IP addresses, browser types and requested pages for security and uptime.
Counting visits
Statistics are sent from your browser to an endpoint on this site, /api/load, which hands them to an analytics provider (EU) that stores them in the European Union. Your IP address is included so an approximate location can be derived. One visit's pages are tied together by a random code in session storage that is deleted when the tab closes, so different visits stay separate. Statistics use no cookies. In the EU, nothing is counted until you choose "Allow".
The analysis link
"Start my analysis" and the other analysis links pass through acnespottreatment.org/spot-scan before reaching acne.today, an independent paid service. The link tells acne.today which site and which button you used, plus the spot type you picked. Anything you then give acne.today, including photos, answers and payment, is covered by its own privacy policy.
Our legal basis
- Statistics from EU visitors: consent. Change it any time with "Statistics choice" in the footer of the home page.
- Statistics from visitors elsewhere and hosting logs: our legitimate interest in a secure, working site.
- Emails: handling your request.
