Inside the app
What is the Pro version?
The same app. Pro dates from when the free version carried ads, and buying it was how you removed them. The free version has had no ads for years and the two are identical, so there is nothing extra to unlock.
It stays on the stores for the people who bought it. If you would like it anyway, treat it as a tip rather than an upgrade: Google Play or App Store.
Is my data sent anywhere?
No. Everything stays on your phone.
