Cipherly — Encrypted Vault, Family Filter & Focus

About

Cipherly is a privacy-first Chrome extension that puts you back in control of your browser. One master password unlocks an encrypted bookmark vault, a family-grade content filter, a focus timer, an activity tracker, and a browser lockdown — all running 100% locally on your device.
