ContentMetricsTool is an internal production and analytics tool operated by Michael Gluska, Märkische Allee 198, 12679 Berlin, Germany (contact: kontakt@michael-gluska.de). The tool is used only by its operator to manage YouTube channels that the operator owns. It is not offered to third parties.
ContentMetricsTool uses YouTube API Services (YouTube Data API v3 and YouTube Analytics API). By authorizing the tool you also agree to be bound by the YouTube Terms of Service. Google's data handling is described in the Google Privacy Policy.
ContentMetricsTool's use and transfer of information received from Google APIs to any other app adheres to the Google API Services User Data Policy, including the Limited Use requirements.

We do not collect personal data of viewers or commenters, do not sell data, do not share Google user data with third parties, and do not use it for advertising or profiling. Data is not transferred to any other app except as needed to operate the tool on the operator's own server.
Access can be revoked at any time in your Google account at https://security.google.com/settings/security/permissions. After revocation, or on request to kontakt@michael-gluska.de, all stored OAuth tokens and YouTube API data for the affected channel are deleted within 7 days. Stored API data is refreshed or deleted at least every 30 days.
This website uses no cookies, tracking, analytics or advertising and loads nothing from third-party servers. It runs on a virtual server rented from Hostinger in a data center in Frankfurt, Germany. Standard server logs (IP address, time, requested page) are kept for 7 days for security and operation of the site (Art. 6(1)(f) GDPR). Further information about the operator's website is in the German privacy statement.
You have the right to access, rectification, erasure, restriction, data portability and objection (Art. 15–21 GDPR), and to lodge a complaint with a supervisory authority, e.g. the Berlin Commissioner for Data Protection and Freedom of Information. Contact: kontakt@michael-gluska.de.
