The irony I mean that the tracking will be there regardless, the suppliers of software will use "we can't monitor the app sufficiently at end users unless we centralize it" as the argument of not making client side software at all.
I write some paid local-only software, and I have no trouble not tracking users or usage. For example, here's the entire privacy policy for one of them:
> App does not collect any data.
> App works completely on-device. Messages do not leave your iPhone and are not shared with other apps.
> The essence of this privacy policy will not change.
--
For another software, the privacy policy includes details such as:
> App never uses the Internet, except to check for updates.
> Automatic update checks can be turned off in the application's preferences. Requests to check for and to download updates happen only through the domain domain.example. The updates server does not store or forward potentially identifying information, such as request IP addresses or user agent strings.
> License keys, obtained upon purchasing App, do not contain personal information, such as names or email addresses of license holders. License keys are validated locally; App does not use the Internet to validate license keys.
