#ArcaneChat doesn't have delivery receipts, only read receipts, the only automatic responses the app does in your behalf is to handle invite links, for that to be abused you first have to share your invite link with a malicious contact, you can get in contact with random/public entity via their invite link and be safe, as long as it is not you the one sharing your invite link!

In #Signal / #WhatsApp as soon as you contact someone or they guess your number you are vulnerable

Another privacy vulnerability caused by the dependency on phone numbers.

In #ArcaneChat (and other #chatmail clients like #DeltaChat) you don't need a phone number (or any private data at all!) to register, so such attacks are simply impossible, keep your family safe, join arcanechat.me



Tool allows stealthy tracking of Signal and WhatsApp users through delivery receipts

A new tool named Device Activity Tracker exposes a privacy flaw in WhatsApp and Signal that lets attackers covertly monitor user activity.

even then most people will not do it, and as said in the previous post, even without phone number discovery, once you get in contact with someone then they can track you in Signal/WhatsApp, imagine you used the app to contact or give feedback to some goverment institution, from that point on they can use this exploit on you, that is not the case with ArcaneChat
