Channel Comparator

Privacy Policy

Updated on 11/15/2026.

What we collect

Channel Comparator requires no sign-up or login. When you compare channels, we query the YouTube API for public data about those channels (name, picture, subscribers, views and videos).

What we store

We keep a daily record of the public numbers of the channels looked up and the list of recent comparisons, for at most 30 days, deleted automatically afterwards. We store no personal data about visitors. The “Your latest searches” list lives only in your browser and can be removed with the “Clear” button. The site's search history (which channels were compared and when, without identifying who searched) is shown to plan holders. No YouTube API data is sold: comparison pages remain free.

Channel owners who connect their channel

When a channel owner authorizes the sentiment analysis, they sign in with their Google Account and grant read-only access to YouTube. We store the channel ID and name, the authorization date and an access token, used only to read the comments on that channel's videos. The authorization lasts 30 days and can be revoked through the link shown after connecting or in Google Account permissions; when revoked, we delete the token, the record and the channel's stored analyses.

Artificial intelligence analysis

To generate the sentiment analysis, the comment texts (without author names) are sent to the Anthropic API (Claude). We don't store the comments; the resulting analysis is kept for up to 30 days for reuse and then deleted automatically.

Contact us

When you send a message through Contact us, we store the text, the type (suggestion, improvement or contact) and, if you provide them, your name and e-mail, only to read and answer the message. We don't store your IP. To ask for a message to be removed, write through the same form.

Payments

Plans (Pedra, Bronze, Silver and Gold) are paid via Pix through Mercado Pago. The e-mail you provide is sent to Mercado Pago to create the charge and is not stored by us. After confirmation, we save a cookie with the access code in your browser, used only to unlock the plan.

Third-party services

We use YouTube API Services; the YouTube Terms of Service and the Google Privacy Policy apply. If there are ads, they are served by Google AdSense, which may use cookies; see how Google uses cookies in advertising.
