FAQ

Questions for extension teams

Which browser extensions can use Mellowtel?

Mellowtel is designed for browser extension developers and is commonly positioned for Chrome, Edge, Firefox, and other Chromium-style extension workflows.

Does it require user consent?

Yes. Mellowtel should be presented as an optional way for users to support your extension, and it starts after they choose to opt in.

How is this different from selling user data?

The model is based on opted-in users helping retrieve public web data. It is not a business model built around selling personal information or browsing history.
