About SimpleToolset
We build privacy-respecting online tools. Most processing happens locally in your browser; when a tool must contact an external service, its page explains what is sent.
Our Security Model
Most tools keep processing in your browser. Some workflows, such as IP lookups, social-media downloads, and optional external services, require a network request and are identified on the tool page.
Local-First Processing
Most tools run entirely in your browser, so their files, text, and data stay on your device.
No Unnecessary Uploads
Files stay on your device unless a tool explicitly says it must contact a network or external service to complete the request.
Browser-Based Processing
Most tools use client-side JavaScript in your browser. Tools that need network data or an external provider show a separate disclosure.
No Account Required
Use any tool instantly. No signup, no login, no personal information collected.
How Client-Side Processing Works
You Load the Page
When you visit a tool, your browser downloads the necessary JavaScript code. This is the only thing that comes from our servers.
You Input Your Data
Whether you're pasting text, uploading images, or entering passwords - your data goes straight into your browser's memory. Not to us.
Processing Happens Locally
Your browser's JavaScript engine performs all calculations, conversions, and transformations. The processing power comes from your own device.
You Get Your Results
For local tools, the output is generated in your browser. Network-assisted tools may receive results from the service identified on their page.
Proof it works: Many local tools continue to work after the page has loaded and the internet connection is disconnected. Tools that need current network data will not.
