NEW DELHI (Reuters) - Apple Inc has agreed to give limited help to the Indian government to develop an anti-spam mobile application for its iOS platform, after refusing to do so based on privacy concerns, according to sources and documents seen by Reuters.

The U.S. tech giant has been locked in a tussle with India’s telecoms regulator for more than a year. Officials complained Apple dragged its feet on advising the government how to develop an app that would allow iPhone users to report unsolicited marketing texts or calls as spam.

The government app was launched on Google’s Android platform last year, but an industry source with direct knowledge of the matter said Apple pushed back on requests for an iOS version due to concerns that a government app with access to call and text logs could compromise its customers’ privacy.

Facing public criticism from the regulator, Apple executives flew to New Delhi last month and told officials the company would help develop the app, but only with limited capabilities, according to a government official aware of the matter.

Apple’s executives have told India that its current iOS platform might not allow for some of the government’s requests, such as making call logs available within the app that would allow users to report them as spam, the official said.

“They (Apple) will help develop an app which, to an extent, can solve the requirements,” said the official.

An Apple spokesman confirmed that the new iOS features to combat spam text messages would help the government build the app, but did not comment on the app’s potential inability to access call logs for reporting spam, as the Android version does.

The spokesman said Apple had not changed its stance on privacy.

Apple’s stand-off with the regulator comes at a time when it is seeking greater access in India, the world’s third-largest smartphone market. The company has been lobbying the government for tax breaks to expand its phone assembly operations in the country, where it reported doubling its revenue versus the previous year for the quarter ending Sept. 30.

Balancing growth and market share with protecting customer privacy has become a defining challenge for global tech companies such as Apple, which regularly clash with governments over allowing access to content on their devices, especially for law enforcement needs.

“This has now become more of an ego tussle between Apple and the regulator,” said Neil Shah of Hong Kong-based technology research firm Counterpoint Research. He added that Apple was unlikely to agree to any requests specific to India because of the precedent that would set.

The chairman of the Telecom Regulatory Authority of India (TRAI) R.S. Sharma said he was unhappy with Apple for not responding swiftly to the government’s requests.

“We’ve told them they are harming their consumers,” Sharma told Reuters in an interview. “I hope good sense prevails upon them.”

Apple did not comment on TRAI’s criticism, but said that it had taken time to develop a privacy-friendly solution.

APP TUSSLE, PRIVACY WOES

Pesky marketing calls and unsolicited commercial text messages have become a big problem in India.

Despite mobile users having the option to register themselves under a so-called “do not disturb” service to block marketers, businesses have gamed the system by using multiple phone numbers for promotions.

TRAI’s anti-spam mobile application, also called Do Not Disturb, has been downloaded more than 100,000 times from the Google Android app section.

Before the app launches, it asks the user to allow it access to contacts and view text messages. Users can then start reporting numbers as spam.

A spokesman for Google, a unit of Alphabet Inc, did not directly comment on the app, but said: “We believe in openness and in the ability of users to make purchasing and downloading choices without top-down enforcement or censorship. Users are prompted with requests for permissions that they can choose to accept or decline.”

Apple, however, has been worried.

“The app can peep into logs, Apple had conveyed that their (privacy) policy does not allow this,” said the industry source familiar with the matter.

TRAI said the app does not raise any privacy concerns.

MEETINGS, E-MAILS

Apple has flown in several overseas-based executives to resolve the dispute with the Indian regulator, including its senior director for global privacy, and former Google executive, Jane Horvath.

At least seven meetings have been held between the two sides and dozens of emails exchanged since last year, according to government officials and documents reviewed by Reuters.

In August this year, months after the talks began, Apple wrote to TRAI saying that a technical meeting would help them establish “what is possible and not possible”.

The TRAI pushed back.

“The whole exercise in organizing the proposed meeting would be a waste of resources ... please share concrete solutions that have a likelihood of addressing the issues we have been discussing over the past one year,” the regulator wrote in September.

Later that month, Apple again approached the TRAI saying it had identified potential solutions but they would require additional discussions with the regulator’s technical staff.

Horvath and other Apple executives met TRAI officials in October and conveyed they would help them develop the first version of the app with limited features.

“They (Apple) are adopting dilatory tactics,” said Sharma, the TRAI chief. “They’ve had meetings, meetings and meetings.”
