I installed Signal a few days ago for the first time and there was definitely a prompt, with an easy way to skip it, before it did the find my friends thing.
The wording also seemed to indicate that only the hashes of the numbers would be uploaded but not sure if thats actually true.
- vidyesh 9y agoHow does Signal know my contact is using Signal? Signal periodically sends truncated cryptographically hashed phone numbers for contact discovery. Names are never transmitted, and the information is not stored on the servers. The server responds with the contacts that are Signal users and then immediately discards this information. Your phone now knows which of your contacts is a Signal user and notifies you if your contact just started using Signal. https://support.signal.org/hc/en-us/articles/115005045728-Does-Signal-send-my-number-to-my-contacts- https://support.signal.org/hc/en-us/articles/115005045728-Do...
