Not exact matches
You'll need to check their phone for common dating
apps, conduct a
google search using personal details like their email address and, if necesary, create test
accounts on popular
apps and sites to see if your signifigant other is returned as a potential match.
I haven't yet installed the
google app store as I don't have an
account there and believe that is a prerequisite.
One other issue I want to point out is the issue of privacy in the
app, at launch the game was able to access your entire
google account with read / write access.
Make sure to go through 2 - factor authentication using
google authenticator
app as it enhance the security of your
account.
