We created SpaceTime to help you leave messages in time or geo-located in space to your family, loved ones or friends. Some of your messages are personal and confidential, so we've implemented end-to-end encryption within our application. When encrypted end-to-end, your messages, photos, videos, voicemails and documents are secure from falling into the wrong hands. In addition, messages you post for more than a year are certified using the BlockChain to ensure the authenticity of the message and its sender when you receive it.


If you want to post high quality photos, videos, audio recordings. If you want to script your documents, record your stories, customize your contents, call on our partner "Eternel.Life".
