Let's say there is an extension that does not collect any user data. At the same time, in addition to free features, this extension also has paid
features. The purchase of a premium subscription to access these features is carried out through a third-party payment service (on its website), which has its own privacy policy. Of course, when making a purchase, users enter (on the payment service website) the data necessary for the purchase, such as a credit card number, email address, etc.
Is it necessary for the extension itself to have a privacy policy in this case?
