# Starting from version 8.0, we collect anonymous data regarding the app (what sounds and features are mainly used, and bug reports), so we can analyze the efficiency of the features.
# We don't collect any of your data other than mentioned above (like your contacts, photoes, calls etc.), as we have no such intents. Literally, we don't have any access to your cookies, other apps, e-mail, cat videos, and so on.
# We use the data that we collect only in order to make the app better. As there are no ads in the app, so there's no need to find out your preferences to sell something to you. '''We don't impart or sell any of this data to third parties.'''
# In any moment of time you can disallow the anonymous data collection and bug reports, in the bottom of Settings tab.
# Paying for subscriptions, you are interacting with Google Billing API, according to its privacy policy; we personally have no access to your credit card number, name or address.
# Also we obtain the info provided by Google Developer Console and its built-in Google Analytics, that is some general data like the app's Google Play page traffic and users' demography. And we don't tell it to any "third parties", as they have no interest in it.
