No cookies, no third-party tracking

This website sets no cookies, uses no local storage and loads no external services (fonts, CDNs, analytics, video platforms). All content, including the videos, is served from this server.

Hosting and server logs

The site is hosted by ALL-INKL.COM – Neue Medien Münnich, Hauptstraße 68, 02742 Friedersdorf, Germany. The host processes technically required data (IP address, time, requested page, browser) in server log files. Legal basis: Art. 6(1)(f) GDPR (secure operation).

Own anonymous statistics

For visitor statistics we store per page view: time, page, language, referring site (domain and, if present, search term), browser language, OS/browser type and a daily rotating hash of IP address and user agent. The IP address itself is not stored; the hash key is discarded daily, so visitors cannot be recognised across days. Legal basis: Art. 6(1)(f) GDPR.

Battery tests

When you start a test we store: test ID, start time, samples (time, battery level, charging state), test mode, OS/browser type, number of CPU cores, screen resolution, time zone and the optional device name. Your browser reads the battery level via the Battery API if supported. This data is public and does not identify you – so please don't use your name as the device name. Legal basis: Art. 6(1)(b) GDPR (providing the requested test). We delete a test on request.

Your rights

You have the right of access, rectification, erasure, restriction, objection and data portability, and the right to lodge a complaint with a supervisory authority.
