You likely gave the "Signing in with Google" apps permission to access such data because you wanted to use your Google login to sign into your accounts with them instead of having to create separate user accounts and passwords.
Several companies such as Edison Software and eDataSource Inc have confirmed they had read emails in order to improve their services.
Despite assuring users to "remain confident that Google will keep privacy and security paramount", the search giant is still reportedly allowing third-party app developers scan through Gmail accounts, the Wall Street Journal has claimed. Some allow people to write emails in special fonts, or to make it easier to find images to send to others, while others make it easier for people to organise their emails into folders.
"Before a non-Google app is able to access your data, we show a permissions screen that clearly shows the types of data the app can access and how it can use that data", wrote Suzanne Frey, Director of Security, Trust, and Privacy for Google Cloud.
The outside app companies receive access to messages from Gmail users who signed up for things like price-comparison services or automated travel-itinerary planners, according to The Journal. Developers swear that manual access is used only оn rare and special occasions and is exclusively to improve customer experience, but we've heard that reasoning enough times to know it's just something PR representatives are forced to say.
Company computers, which scan some 100 million emails a day, were "trained" by workers who personally read thousands of emails. The increased scrutiny follows the Cambridge Analytica scandal, in which a data firm was accused of misusing the personal information of more than 80 million Facebook users in an attempt to sway elections. It may do some internal testing to make sure of this, as well. Google does little to police those developers, who train their computers-and, in some cases, employees-to read their users' emails, a Wall Street Journal examination has found.
The report has specifically mentioned two apps in its report, Return Path and Edison Software. According to the newspaper, nothing in Microsoft or Yahoo's policy agreements explicitly allows people to read others' emails.
