Cross-platform encrypted messaging service Signal surge to 1 million installs every day after Facebook-owned WhatsApp updated its privacy policy.

About 810,000 users globally installed Signal on Sunday, nearly 18-fold compared with the download numbers on Jan. 6, the day WhatsApp updated its privacy terms, according to data from research firm Apptopia.

WhatsApp’s new privacy terms reserve the right to share user data, including location and phone number, with its parent Facebook Inc and units such as Instagram and Messenger.

To cope with the number of new users, Signal said on Sunday it had added more servers to handle the traffic. Up until recently, the non-profit app was largely used by journalists and human rights activists looking for a more secure and encrypted mode of communication.
