Why browser-side encryption matters
Most self-destructing link services like Privnote decrypt the content on their servers or store keys on their backend database. ProtectedShare uses a **Zero-Knowledge** architecture: all encryption and decryption happens inside your browser using JavaScript's Web Crypto API. The decryption key remains in the URL hash fragment (the part after the `#` symbol), which is never sent to the network or stored in our database. If our database is ever breached, your secrets remain mathematically impossible to read.
No ads, no trackers, pure privacy
Unlike legacy tools that monetize via display ads and cookies, ProtectedShare is completely free, open-source, and does not run any analytics trackers or display ads. Your session is completely anonymous.
