The short version
No accounts, no personal data collected. MAC addresses you look up are processed to return a result and are not stored against you.
What we collect
Standard server logs (IP, page, browser) are kept briefly for security and abuse prevention, then aggregated into anonymous counts. If analytics is enabled we use Google Analytics to understand which pages are useful; block it with any content blocker and the site works identically.
Cookies
One preference in local storage: your light or dark theme choice. It never leaves your device.
The API
API requests are rate-limited by IP for fairness. We log request counts, not the specific MACs tied to you.
