Protected MSG is a free web based service that allows users to create notes that they can share over the internet as unique one-time-use HTTPS URLs which expire after its first access via any web browser. Optionally you can attach a file, which will be send along with the encrypted message. You can share your links via SMS/E-mail/Messanger/Whatsapp and any other service you like.
We also have a secure and encrypted chat functionality (similar to Facebooks' messenger) where you can discuss with your friends without worrying that you will be spied on.
