- balladeer 8y agoTo be fair it does that to map you with the contacts who also are on Signal just like WhatsApp or Telegram does. Though you could also use Telegram just with user_names w/o phonebook permission but for signing up you need to use your actual phone number.
- jlund 8y agoThe Contacts permission is completely optional, and contact information is never stored: https://signal.org/blog/private-contact-discovery/ https://signal.org/blog/private-contact-discovery/
- ppjet6 8y agoThis seems like smoke and mirrors to me: Traditionally, in Signal that process has looked like: The client calculates the truncated SHA256 hash of each phone number in the device’s address book. The client transmits those truncated hashes to the service. The service does a lookup from a set of hashed registered users. The service returns the intersection of registered users. The phone number space is really not this big.
