Choco - Privacy-First Browser Session Sync Dashboard

The Problem We All Face

Picture this: You're working on your laptop, deeply engaged in multiple web applications. You have Gmail open, your project management tool, GitHub, Stack Overflow, and a dozen other tabs with active sessions. Everything is authenticated, everything is running smoothly.

Then you switch to your desktop. Or grab your phone. Suddenly, you're back to square one—logging into every single service again, going through 2FA flows, remembering passwords, and waiting for session cookies to establish. It's frustrating, time-consuming, and breaks your workflow.

What if your browser sessions could follow you across all your devices, automatically and securely?

Enter Choco

Choco is a privacy-first browser extension and cloud service that securely syncs your browser sessions across all your personal devices with end-to-end encryption.

No more repetitive logins. No more lost sessions. No more friction. Just seamless, secure, automatic synchronization of your authenticated sessions across every device you own.

End-to-End Encryption

All session data is encrypted before leaving your device. Your credentials never exist in plain text on our servers.

Automatic Sync

Seamlessly sync cookies, localStorage, and sessionStorage across all your devices in real-time.

Privacy-First Design

You control what gets synced. No tracking, no analytics, no data mining. Your data stays yours.

Cross-Device Harmony

Login once, access everywhere. Your authenticated sessions follow you across desktop, laptop, and mobile browsers.

How It Works

1

Configure Your Platforms

Define which websites you want to sync and what data to collect (cookies, localStorage, sessionStorage). Choco gives you granular control over every aspect.

2

Automatic Monitoring

The extension monitors your configured websites in the background, detecting when you log in and capturing session data securely.

3

Encrypted Sync

Session data is encrypted on your device before being synced to your private storage. Your credentials never exist in plain text on servers.

4

Seamless Restoration

When you visit the same website on another device, Choco automatically restores your session. You're instantly logged in without any manual intervention.
