Google Admits Giving Hundreds Of Firms Access To Your Gmail Inbox

Alphabet Inc's Google gave details about its policies for third-party Gmail add-ons but stopped short of fully addressing questions from U.S. senators about developers who break its email-scanning rules.

How user data flows between big technology platforms such as Google and Facebook Inc and their partners has faced scrutiny around the world this year since Facebook revealed it had done little to monitor such relationships.

Google said in a letter to U.S. senators made public on Thursday that it relies on automated scans and reports from security researchers to monitor add-ons after launch, but did not respond to lawmakers' request to say how many have been caught violating the company's policies.
