Security & Privacy
Your safety is our top priority. Learn how we protect your sensitive information.
Client-Side Processing
Your files are hashed directly in your browser using the Web Crypto API. They never leave your device or touch our servers.
SHA-256 Encryption
We use the same cryptographic standard trusted by banks and governments worldwide to create unique file fingerprints.
Hedera Hashgraph
Hash timestamps are stored on Hedera's enterprise-grade distributed ledger, making them immutable and publicly verifiable.
Secure Infrastructure
Our servers run on enterprise-grade cloud infrastructure with encryption at rest and in transit.
Zero-Knowledge Design
We store only cryptographic hashes and metadata. Even we cannot see or reconstruct your original files.
Regular Audits
Our security practices are regularly audited by independent security professionals.
How Your Data Stays Private
You select a file
Choose any image, video, or document from your device.
Browser hashes locally
Your browser generates a SHA-256 hash. The file stays on your device.
Hash sent to server
Only the hash (a 64-character string) is sent to our servers.
Recorded on Hedera
The hash is timestamped on the blockchain, creating permanent proof.
