Security
Security by Design — Not by Promise
Security by Design — Not by Promise
Most document tools rely on securing your files after they are uploaded. SecureDoc takes a different approach.
Your files never leave your device.
By eliminating file uploads entirely, SecureDoc removes a major category of security and privacy risks.
How SecureDoc Protects Your Data
SecureDoc processes all files locally in your browser instead of sending them to remote servers.
This means:
Your data remains fully under your control throughout the entire process.
Fully Client-Side Architecture
All operations are executed directly within your browser using modern web technologies and trusted open-source libraries.
This includes:
Because processing happens locally, there is no exposure to external systems.
Encryption & Data Protection
SecureDoc uses modern cryptographic standards where applicable, including:
- AES-256 encryption via browser-native APIs
- ChaCha20 for efficient secure operations
- Elliptic Curve Cryptography (ECC) for secure key handling
Encryption is applied to features that require additional protection, such as secure file handling and advanced workflows.
What SecureDoc Does NOT Do
Security is as much about what you avoid as what you implement.
Secure Authentication
For advanced features, SecureDoc supports authentication through trusted providers:
We do not store passwords. Authentication is handled via secure OAuth flows, and only minimal account information (such as name and email) is accessed.
Infrastructure Security
SecureDoc is delivered over secure, encrypted connections:
- HTTPS enforced across all pages
- Modern TLS configurations
- Secure hosting environment
Transparency
We believe security should be verifiable, not assumed.
- Built using well-known open-source technologies
- No hidden data processing
- Clear third-party disclosures
Limitations
While SecureDoc significantly reduces risk by design, no system is completely risk-free.
- Security depends on the integrity of your device and browser
- Malicious software on a device may affect local processing
- Users are responsible for maintaining a secure environment
