Privacy policy
Updated: 23 October 2026
In short
There are no accounts and we never ask for your email. Every check runs entirely in your browser: the address you paste is never sent to us, stored, or put in the page link.
What stays on your device
Your browser stores your theme and your cookie choice locally. The scheme you pick may appear in the page link (?s=esta), which you share only if you want to. None of it reaches us.
Analytics and session replay
Only if you accept, we use PostHog (EU-hosted) for usage statistics, error reports and session replay. Events record the verdict and which warning signs fired, never the address you checked. Text fields are masked in recordings. You can change your choice any time from “Cookie settings” in the footer.
Links to other sites
Official-site and reporting links open the government or consumer-protection page directly. We don't use affiliate links and nobody pays us to list a site.
Payments
Nothing is for sale. The planned Pro features are marked “coming soon”; we process no payments and collect no card details.
Your rights
You have the right to access, correct, erase and object (GDPR). For any question, open an issue on the project's GitHub page.
