SpiderOak Semaphor is an encrypted group chat & file-sharing software for your team, friends, or family! Email sucks, collaboration rocks. Faster uploads, sharing & search than the other guys. Offline mode. Mobile & desktop. Password-less design. Unparalleled privacy.

Privacy isn’t the only perk of Semaphor. Whether you are busy working on a project, organizing an event, or creating a discussion around a special topic, use SpiderOak Semaphor to help. Get started by creating as many Teams and Channels as you want. Then invite your friends, family, or coworkers. Start communicating and collaborating securely. (Bye-bye email!) You can even create your own personal channels for saving notes, links, files, ideas, and anything else you may need. You'll never need to email a file to yourself again.

From its password-less design to fast file sharing, the program is the only group chat application that is built from the ground up for privacy and security. With the tool, you never have to remember a password, pre-encrypt a sensitive document, or worry about a third party reading your messages. Your data is only visible to you and the people you choose to share it with. No one else.

The app retains your conversations and data from day one. If you ever need to go back and find a file or conversation, use the search bar — even if you’re not connected to the internet. Standard and Pro accounts have access to unlimited conversation history. Because Spider Oak Semaphor is an application downloaded to your device, and not in a web browser, the search is crazy fast. Other perks of being an application on your device include multi-file uploads, concurrent downloads (you can start downloading a file before it's even finished uploading!). Large file support up to 2GB.

No matter what you're working on or searching for, you can stay productive on your mobile device or at your desk. Unlock unlimited search history for only $9/month.

Note: 30 days trial version.
