FAQs

Frequently Asked Questions

When a message is sent, it routes via our servers to the recipient. If the recipient is not online at the time you sent the message, the message will wait on our servers until they do. During that time we cannot read the message - it was encrypted by the sending device and we only have the encrypted version. Once the recipient comes online and we deliver your message to their handset - a small grey dot is shown on your screen next to that message. This will turn into a green dot once they have read your message

Semafore is a messaging tool that is designed for organisations, not private individuals. As such the visibility of whether a message is reported as seen or not is set by the organisation.

Note that this is the issuing of read receipts, regardless of organisation. If User A1 is in Organisation A and A has determined that user A1 will not issue read receipts, User B2 in Organisation B that does permit read receipts to be issued, will not be able to tell if User A1 has read or not read B2's' message. Meanwhile if A1 sends a message to B2, A1 will be able to tell if B2 has read it.

When Semafore is first opened, or opened after a period of being in the background, it connects to our server and conducts a 'cryptographic-handshake' to report that it is now online and able to receive / send messages. This opening up of a crypto tunnel takes a little while - cryptography (encryption) is mathematically challenging and hence the 'delay' whilst it completes.

  1. end-to-end encryption
  2. cannot be read on our servers
  3. due to the advanced cryptography used we need to ensure no bad actors - hence only sold to organisations that have a footprint (ie listed in a government published corporate register)
  4. all code libraries are either developed by ourselves or sit under our control - no ability for a bad actor to conduct a supply chain attack and introduce malicious code into an inherited library
