Encryptr was a free, open-source, zero-knowledge password manager and digital wallet developed by the privacy-focused software company SpiderOak. It was built using SpiderOak’s “Crypton” application framework, which was designed to ensure that user data was encrypted on the local device before ever being sent to the cloud.
However, Encryptr is no longer actively maintained or available for download from official app stores, having been discontinued several years ago. Key Features of Encryptr
When it was active, Encryptr positioned itself as a highly secure, albeit minimalist, option in the password management space.
Zero-Knowledge Architecture: SpiderOak acted strictly as a host for scrambled ciphertext. They never had access to user encryption keys or master passphrases, meaning they could not read the data even if subpoenaed or hacked.
Ultra-Simple Interface: Unlike complex modern password managers, Encryptr kept options strictly limited to store only three types of data: passwords, credit card numbers, and general text notes.
Cross-Platform Synchronization: It utilized NW.js (Node-Webkit) and Cordova codebases to automatically sync vaults across Windows, macOS, Linux, and Android devices.
Completely Free: It was released as a fully free utility with no hidden subscription walls for its core features. Why was it discontinued?
Because Encryptr was built as a proof-of-concept for SpiderOak’s JavaScript-based Crypton framework, its development stalled when the underlying framework lost traction. Users on communities like Reddit’s privacy forums noted its sudden removal from repositories. Since it lacked critical modern features like automated browser auto-fill, secure password sharing, and biometric integrations, it was ultimately phased out. Modern Alternatives
