I just read the following section on the developer agreement:
3.5 You may also choose to distribute Products for free. If the Product is free, you will not be charged a Transaction Fee. You may not start charging a user for a Product that was initially free unless the charge correlates with an alternative version of the Product. The Payment Processor must process all fees a Developer receives for any version of a Product distributed via the Store.
After reading i am not sure if we are allowed to add IAP to a free app that didn´t had any IAP before or not? They are implying that is ok if its a different version but to they mean another app like “XXX Pro”?
Are there any forms to contact google and ask this?
Hi there that doesn´t make much sense since you cant do that on google developer console once you set free you cant change but wait i asked google about this and this is their response:
Hello,
Thank you for contacting the Google Play Team.
At this time we are unable to comment on your planned implementation. It would be recommended to submit a separate version, if you’d like a paid version of your app.
You may want to review our program policies before submitting your app.
Maybe they didn’t understand, and as usual, Google isn’t answering straight, but very generic.
They could just reject your update, or give an alert in the apk as soon as you upload. Or just block it, as they do when your application is free not allowing you to change the price (Apple is handling this much better).
