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.

Frequently Asked Questions

What makes ProtectedShare a good Privnote alternative?

ProtectedShare provides client-side zero-knowledge encryption using the browser Web Crypto API. Unlike older tools like Privnote, which can run intrusive display ads and third-party trackers, ProtectedShare is 100% open-source, runs zero tracking scripts or cookies, and supports advanced developer features like EnvShare (.env configuration sharing).

Is Privnote really end-to-end encrypted?

While legacy services claim encryption, many perform decryption on their servers or require the key to be sent to their backends. ProtectedShare performs AES-256-GCM encryption client-side, storing the decryption key in the browser's URL hash (after the `#` symbol), ensuring that not even the hosting server can read your secret.

Does ProtectedShare store logs of my IP or secrets?

No, ProtectedShare operates a zero-tracking model. We do not store IP addresses or connection details, and our database records are set to immediately auto-destruct upon reading or expiration.
