Facebook’s WhatsApp is changing its privacy policy on Feb. 8, when it will begin to share some user information with Facebook, including location, phone numbers, profile names and pictures, when you last logged online and more. People are now flocking to an alternative texting app called Signal that doesn’t collect your data.

According to Reuters, daily downloads have increased 18x since WhatsApp changed its privacy policy, topping more than 800,000 downloads daily. That was likely partially boosted by Tesla CEO Elon Musk, who tweeted ‘use Signal,’ earlier this month.
