Security & Data Protection

There is No Server.

Traditional web tools upload your documents to a server, process them, and promise to delete them later. Toolzum skips the server entirely — your files load into browser memory, process locally via WebAssembly, and are downloaded directly. There is nothing to intercept, no server to breach, no file to delete.

Server-Based Competitors

— Upload your file to a cloud server
— Process on remote infrastructure
— Promise to delete after 2 hours
— 2-hour breach window exists

No Server to Breach.

— Files loaded into browser memory via File API
— Process locally via WebAssembly
— Nothing to delete — no server, no upload
— Zero breach surface for file data

Zero-Upload Architecture

Your files are loaded directly into browser memory via the File API. They never traverse a network, never reach a server, and never exist anywhere but your device.

No Data to Breach

Competitors advertise 'auto-delete after 2 hours' — but that 2-hour window is a breach risk. If there is no server, there is no server to breach. Your files exist only in your browser session.

No Telemetry on Your Content

We run zero analytics on file contents, filenames, or processing outcomes. No tracking pixels, no session replays, no metadata collection on what you process.

Works Offline

After the initial page load, Toolzum functions without any internet connection (local-processing tools). No network dependency during file operations.

Architecture

All processing via WebAssembly (WASM) — compiled C++, Rust, and Python libraries execute in your browser's sandboxed worker thread
Zero data transmitted to external servers during file operations
Static edge delivery via global CDN — no application servers, no file storage buckets
Session management and payments are the only server-side operations, and they never touch your files

Encryption & Data Flow

Your file → Browser memory (File API) → WASM processing → Browser memory → Download
Files are never uploaded, cached, logged, or stored on any server
After download, file data is garbage-collected by the browser — no retention window
All network communication encrypted via TLS 1.3 with HSTS

Infrastructure & Privacy

Global edge CDN with 330+ locations for fast static delivery — no application servers
Local-processing tools keep your files entirely in your browser — no server round trip
Client-side compute architecture — inherently auditable and transparent
Cloud AI tools are clearly marked so you always know when data leaves your device

Enterprise Security Controls

Content Security Policy (CSP) headers — restricts all outbound connections by policy
Subresource Integrity (SRI) — all open source libraries loaded with cryptographic integrity hashes
X-Content-Type-Options: nosniff, X-Frame-Options: DENY, strict Referrer-Policy
No third-party cookies, no advertising scripts, no external tracking on tool pages

Privacy Architecture

Built for Sensitive Work

Corporate policies forbid uploading financial data, medical records, or sensitive contracts to external servers. Toolzum runs locally in your browser — your files never leave your machine.

Zero-Trust Architecture

Local-processing tools run in your browser via WebAssembly. Your data never touches our servers.

No Data to Regulate

Because files never leave your device, there is no data to regulate. Toolzum's browser-native architecture processes everything locally.

No Cloud Storage

Files are processed in browser memory and immediately garbage-collected. Nothing is cached, logged, or stored. No shadow IT risk.

Corporate Policy Safe

IT administrators can whitelist Toolzum without data exfiltration concerns. No API calls to external AI models. No upload queues. No data leaks.

Confidential by Design

Documents stay in your browser session — they never reach a server. Suited for contracts, financial records, and other sensitive material.

Works Offline

After initial page load, Toolzum functions without internet access (local-processing tools). No network dependency for file operations.

Local-processing tools keep data on your device. No accounts needed for most tools. No logs. No tracking. Toolzum is designed with privacy as the default.

Toolzum does not provide legal or regulatory compliance certification. Consult your compliance team for your specific requirements.
