+# Implementation of local differential privacy for android app with  Google Analytics/Firebase
+
+Following [codelab tutorial.](https://codelabs.developers.google.com/codelabs/firebase-analytics/index.html?index=..%2F..index#0), I have implemented Google Analytics with Firebase. I was able to log in analytics events in a sample android app.

+From [https://firebase.google.com/support/privacy] "Firebase customers typically act as the "data controller" for any personal data about their end-users they provide to Google in connection with their use of Firebase, and Google is, generally, a "data processor".
+This means that data is under the customer's control. Controllers are responsible for obligations like fulfilling an individual's rights with respect to their personal data."
+
+To be able to use Google Analytics I as developer have to make sure that I have the right consents in place for users who download my app.
+
+I have decided to explore the possibility of offering app users local differential privacy.
+
+I have tried to use randomized response.
+The technique used to add randomness to the response is following instructions (assuming yes/no question):
+
+1.Flip a coin 2 times.
+
+2.If the first coin flip is heads, answer honestly
+
+3.If the first coin flip is tails, answer according to the second coin flip (heads for yes, tails for no)!
+
+Thus, each answer is now protected with "plausible deniability". If thee answer "Yes" to the question "have you committed X crime?", then it might becasue they actually did, or it might be becasue they are answering according to a random coin flip. Each person has a high degree of protection. Furthermore, we can recover the underlying statistics with some accuracy, as the "true statistics" are simply averaged with a 50% probability. Thus, if we collect a bunch of samples and it turns out that 60% of people answer yes, then we know that the TRUE distribution is actually centered around 70%, because 70% averaged wtih 50% (a coin flip) is 60% which is the result we obtained.
+
+I have implemented local differential privacy in onclick method.

+
+The user have hight privacy and the acuracy goes up as number of app downloads increase.
