Introducing YourKeep: The Stateless Cryptographic Backup Tool for Digital Sovereignty

Today, we are proud to introduce YourKeep, a local-first, zero-knowledge cryptographic backup application engineered to protect your most critical files against account terminations, hardware degradation, and the passage of time.

In a world where consumers have been trained to store everything inside centralized cloud subscription services, YourKeep offers a radical, mathematically proven alternative: Stateless Data Resilience.

The Modern Data Storage Paradox

We live in an era of unprecedented digital abundance. We hold our entire life’s memories, legal records, medical histories, and intellectual property on flash drives and cloud servers.

Yet, our ownership of this data has never been more fragile:

• Centralized Account Lockouts: Algorithmic content moderation systems frequently flag and terminate innocent user accounts with zero human appeal recourse.
• The Subscription Treadmill: Cloud providers hold your historical archives hostage behind perpetual monthly fees. If you stop paying, your data is erased.
• Correlated Single Points of Failure: Sync engines faithfully upload ransomware infections and accidental deletions across all your devices in seconds.

The YourKeep Architectural Difference

YourKeep does not attempt to replace your hard drives or cloud storage providers. Instead, it sits directly in front of them as an impenetrable cryptographic protection layer:

1. Pure Local-First Execution

YourKeep runs entirely on your local machine. No file, key, or master passphrase ever touches our servers—because we run no servers.

2. Quadruple-Failure Tolerance (6-of-10 Default)

Your files are transformed into 10 independent self-describing fragment files. Any 6 fragments restore 100% of your data. You can lose four storage providers or physical drives simultaneously without losing a single byte.

3. Open, Future-Proof Recovery Protocol

The YourKeep V1 container format is fully documented and open. Your ability to reconstruct your archives in 30 years does not depend on our company’s survival—it depends solely on open mathematics.
