Thanks for taking the time to leave feedback. We'd like to clarify a few points.

* You don't need to sign in to use the extension with the built-in local voices. An account is only required if you choose cloud voices or other account-based features.
* The built-in local voices are completely free and include unlimited listening.
* Cloud voices are different because each request has a real operating cost. We include free usage, and only charge if you choose to continue using those premium voices beyond the free allowance.
* The extension doesn't automatically prompt users to upgrade when they start listening. Upgrade options are only shown if you choose to view them.

If you experienced something different, we'd appreciate the opportunity to investigate. Please contact our support team with a few details, and we'll be happy to help.
