WhatsApp's new privacy policy is making many people reconsider the messaging app. Experts have suggestions for alternatives.

The new privacy policy has some concerned because it allows WhatsApp to share messages with its parent company, Facebook. WhatsApp recently said that users who do not agree to the policy by May 15 will no longer be able to send or read messages through the app. Fortunately, there are many other secure messaging apps available if you do not agree to WhatsApp's terms.

“The best alternative is to switch to a messaging service like Signal, which doesn’t collect user data or share it with Facebook or other third-party advertisers, but does offer strong end-to-end encryption for messages,” Ray Walsh, a data privacy expert at privacy website ProPrivacy, said in an email interview.

If you don't agree to WhatsApp's privacy policy, you can still receive calls and notifications, but this will reportedly only be possible for a short period of time.
