Privacy policy

ChannelDoctor (“we”, “us”) gives YouTube creators an audit of their channel. This policy explains what data we access, how we use it, and the choices you have. ChannelDoctor is operated by CK Studio, available at doctor.ckstudio.cc.

What we access

When you choose “Sign in with Google” or “Check my channel”, you grant ChannelDoctor these permissions:

• Basic Google profile (name, email address, profile picture) so we know who is signed in.
• Read-only access to your YouTube account (youtube.readonly): your channel's name, picture and public statistics, and the list of your uploaded videos with their titles, publish dates, durations, privacy status, views, likes and comment counts.

We cannot upload, edit, delete or comment on anything. We never see your Google password.

How we use it

• Only to generate and show your channel audit and the recommendations in it.
• We do not sell your data, use it for advertising, or share it with anyone except the service providers needed to run ChannelDoctor (for example, our hosting provider), who process it on our behalf.
• When AI-written insights are added, the computed statistics of your channel (not your Google sign-in details) may be sent to an AI provider (Anthropic or Google) solely to write your report. They are not permitted to use it to train their models.

Google API Services User Data Policy

ChannelDoctor's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

YouTube API Services

ChannelDoctor uses YouTube API Services. By using ChannelDoctor you are also subject to the YouTube Terms of Service, and Google's handling of your data is described in the Google Privacy Policy.

Storage and retention

• Your sign-in is kept in an encrypted cookie on your device. It contains Google access tokens, never your password.
• Your latest audit is kept temporarily on our server (currently up to 30 minutes) so pages load quickly.
• If we later store saved reports, YouTube data will be refreshed or deleted at least every 30 days, as YouTube's policies require, and deleted when you disconnect or ask us to.

Your choices

• Click Disconnect in ChannelDoctor at any time. This revokes our access at Google and signs you out.
• You can also remove access from your Google account at myaccount.google.com/permissions.
• To ask for a copy or deletion of any data we hold about you, email us (below).

Cookies

We use only essential cookies: one to keep you signed in and one to protect the sign-in step. We remember your light/dark theme choice in your browser. No advertising or tracking cookies.

Children

ChannelDoctor is not intended for children under 13 (or the minimum age in your country).

Changes

If we change this policy, we will update the date above and, for important changes, tell you in the app.
