After months of back and forth, Apple has permitted Indian telecom regulator TRAI to release its anti-spam app on the App Store. The app, called TRAI DND - Do Not Disturb , went live on the iPhone app store on Friday. The free app, a version of which has existed on Android platform since 2016, allows customers to block unsolicited texts and calls from marketers, a rampant issue that continues to plague customers in India The app has been the subject of months-long, heated argument between Apple and TRAI . Apple had argued that the app, which by design accesses message and call logs of a user, violates its privacy policy.

Sharma, who heads the Telecom Regulatory Authority of India, had threatened to take legal action against Apple. "This is unjust, it shows the approach and attitude of this company," he told Reuters in March
