Do you know what the problem with start.io is?
If you know, better you never ever use this platform again.
And if you don’t know, let me inform:
start.io was stealing sensitive data from devices and selling them with third party. Yes, you heard you right. They were selling personal data from all your users from long ago. As per the notice by Google, start.io has acknowledged that they were selling those data. Therefore, Google restricted using it.
Also, as per Google, it’s your responsibility to ensure that you’re not sharing any sensitive user data with third party (i.e : Your Ad network). If you’re doing this thing repeatedly, your account and/or app could be banned permanently.
