WASHINGTON, Sept 22, 2018 (News Wires) - Alphabet Inc's Google gave details about its policies for third-party Gmail add-ons but stopped short of fully addressing questions from US 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 US senators made public yesterday 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. Senators may seek further clarity on Gmail's operations at a Commerce Committee hearing about privacy practices scheduled for September 26 with officials from Google, Apple Inc, AT&T Inc and Twitter Inc. Google did not immediately respond to a request for comment. Gmail users must give their consent to activate extensions, which can help them send emails on a time delay, get price-match rebates from retailers and remove unwanted mailing lists. Under Google's policies, software firms that create these add-ons must inform users about how they collect and share Gmail data
