Hi

What makes you believe that this is happening?

Well, that's what the DuckDuckGo tracking blocker reports

We use Leanplum SDK for some users of Firefox for Android, but we don't track your postal code.

Here's the info from our configuration:

"region" -> "(detect)"                // Not used. We strip play-SERVICES-location so this is will be the default stub value in Leanplum SDK.
"city" -> "(detect)"                  // Same as above.
"country" -> "(detect)"               // Same as above.
"location" -> "(detect)"              // Same as above.

Thanks for the explanation.
