Snap points out that its Snapchat app is a free download, available to everybody.

The accusations were found in documents from a lawsuit between Pompliano and Snap Inc., Snapchat's parent company.

Snapchat is strongly denying allegations by a former employee Anthony Pompliano, who had alleged in a lawsuit that CEO Evan Spiegel had once shot down his suggestion to pursue growth in certain global markets. "I don't want to expand into poor countries like India and Spain", Spiegel is alleged to have said.

According to Variety magazine Snapchat has previously argued that Pompliano's suit contained "trade secrets that could damage the company and help its competitors".

The critical remarks about the company by Pompliano stem from his lawsuit in which he claimed he was sacked from his position after he questioned Snapchat's internal methods for calculating daily active users. Hashtags like #BoycottSnapchat and #Uninstall Snapchat have also started trending on Facebook and Twitter.

The comments have caused a major furor in India, with thousands of Indians down-rating the app on online stores and uninstalling it.

"Obviously Snapchat is for everyone!" a spokesman told Newsbeat.

While speaking to a youth website, Fernandes said that he has no bad feelings against Spiegel and has created the app just for fun.

A group of hackers in India claims it has siphoned the private information of 1.7 Snapchat users and leaked it on the darknet, payback for Spiegel's "arrogance".

Pompliano's lawsuit accuses executives of exaggerating user data to mislead advertisers. "We are grateful for our Snapchat community in India and around the world", Snap said in a statement.
