About TechSimpleHub
We build free, fast, and genuinely private developer tools — because privacy should be the default, not a premium feature.
Privacy by Architecture
We don't collect your data because we technically can't — all processing happens inside your browser. There's no server receiving your JWTs, hashes, or subnets.
Zero Friction
No accounts. No subscriptions. No email verification. No cookie banners beyond what's legally required. Open the tool. Use it. Close it.
Built for Everyone
Whether you're a network engineer, backend developer, or just learning — our tools explain concepts with RFC references and visual diagrams.
Our Story
TechSimpleHub was born out of frustration. As developers, we constantly found ourselves searching for quick tools to decode a JWT, calculate a subnet, or generate a SHA-256 hash — only to land on slow, ad-ridden sites that required account sign-ups, sent inputs to unknown servers, or had confusing interfaces buried under popups.
We decided to build the tools we wished existed: fast, clean, client-side, and educational. Every tool on TechSimpleHub includes not just the utility itself, but the explanation — the RFC references, the architecture diagrams, the underlying mathematics — so you leave understanding more than when you arrived.
We're developers, not data brokers. The business model is straightforward AdSense advertising on educational content. Your inputs are never part of any transaction.

🛡️ Privacy Philosophy
No Server Logging
We have no application server. There is literally no backend to log your inputs.
No Account Required
We do not collect email addresses, usernames, or any identifying information.
No Input Telemetry
Your JWT tokens, IP addresses, hash inputs, and Base64 strings never leave your browser.
Advertising Transparency
We use Google AdSense. Google may set cookies for ad personalization per their privacy policy.
Analytics
We use privacy-respecting analytics (Cloudflare Analytics) that does not fingerprint users.
