TeamWork.io is a public bulletin board where you can post hidden messages to anyone, both individuals or teams of people simultaneously, legible by only you and them.
Seamlessly find your friends' public keys from open key servers, and create private group messages that only they can read.
All encryption happens on your client, under SSL, and you never have to upload or reveal your private keys to us or anyone else, ever.
This service will always be free of charge to use, and free of ads and trackers.
Support Us with a Donation to help keep it that way.
Unless you turn encryption off, no message text is visible to anyone who does not possess the correct private key.
Review the source code on github and fork it (contributions are welcome), or clone it to run on your own servers, under your domain.
