How It Works
Three steps to lock down your documents for good.
1. Add Your Important Files
Drop in contracts, financial records, medical files, or anything you need to keep safe.
2. Lock Them Down
AES-256 encryption locks your files in your browser — before they ever touch our servers.
3. Come Back With Confidence
Access your files anytime. Need proof they existed on a specific date? We've got that too.
Everything You Need to Protect Critical Documents
