Reminder—If you’ve forgotten about any Google app after using it once a few years ago, be careful, it may still have access to your private emails.
When it comes to privacy on social media, we usually point fingers at Facebook for enabling third-party app developers to access users personal information—even with users’ consent.
But Facebook is not alone.
Google also has a ton of information about you and this massive pool of data can be accessed by third-party apps you connect to, using its single sign-on service.
Though Google has much stricter privacy policies about what developers can do with your data, the company still enables them to ask for complete access of your Google account, including the content of your emails and contacts.
