How Does It Share Your Data?
Signal requires a phone number to sign up, and claims it can optionally discover which of your contacts are Signal users in order to protect the privacy of your contacts as well. All messages are end-to-end encrypted and Signal claims it will not decrypt it. Signal also does not sell, share, or monetize personal data in any way.
- No data stored or shared.
- Video calls only possible on mobile apps and with one person at a time.
It does not appear that Signal has ever suffered from a major data breach. Signal is the messenger of choice for many investigative journalists, politicians, and other privacy-minded officials, including Edward Snowden. If you are concerned about your text information being exposed, this app will ensure that you will never have to worry about that.
