Safenote is the free, fast, and secure way to share files and notes with end-to-end encryption and a link that expires automatically. And also it's a free cloud-based service that is functioning via an encrypted SSL tunnel. Safenote doesn't require you to create an account before start using the service and no password or email required. This free service enables you to send a self-destructing message or file to someone. This means once they view the message or download the file, they will no longer be able to access it again after the view count has reached zero. This ensures your message is read by no one but the reader and all evidence of the message is erased. Messages are also anonymous unless you add any identifiable information to your message. If you share your passwords or private, sensitive data via email or chat, copies of that data are stored in a number of locations. If you use Safenote instead, the data stays for a single viewing, which ensures that someone else can't read it later. It allows you to send sensitive information in a secure manner, ensuring that only one person can see it.
