Signal is a free, open-source, software that offers end-to-end message and phone call encryption, as well as multimedia and file transfer. Signal does not track or store meta-data. It only stores your phone number and the last time you used the app — it does not store information about who are in contact with.
Sending documents, tips and information by mail is a secure way of protecting your information. For the most secure method please do not include a return address.
