mugen-stats is a private tool used only by me, the owner of the YouTube channel it reads.
What it reads: the YouTube Analytics and YouTube Data numbers for my own channel (views, watch time, subscribers, traffic sources and similar), with read-only access. It can't change anything on the channel.
Where it goes: the numbers are stored in a private repository and shown on a password-protected page that only I can open. A daily summary is sent to my own email and Discord.
Sharing: nothing is sold or shared with anyone, and no data about any other Google user is collected.
Removing access: access can be withdrawn at any time from the Google account's security settings (Third-party apps with account access).
Use of information received from Google APIs follows the Google API Services User Data Policy, including the Limited Use requirements.
