Frequently asked questions
Everything you need to know about Toolplex.
Is Toolplex really free?
Yes — 100% free, forever. There are no hidden paywalls, premium tiers, or usage limits. Every tool on Toolplex is free to use as many times as you like.
Does Toolplex store or collect my data?
No. Everything runs entirely in your browser. Your files, text, and inputs never leave your device. We have no servers processing your data and no analytics tracking what you type.
Do the tools work without an internet connection?
Most tools work offline once the page has loaded since all processing is client-side. A few tools that fetch external data (like API Status Aggregator) do require internet access.
Do I need to create an account?
Never. There is no signup, no login, and no email required. Just open a tool and start using it immediately.
Which browsers and devices are supported?
Toolplex works on all modern browsers — Chrome, Firefox, Safari, and Edge. Tools are responsive and usable on desktop, tablet, and mobile devices.
How is Toolplex different from other online tools?
Most online tools send your data to a server for processing. Toolplex is entirely client-side — your data never leaves your browser. No ads, no tracking, no accounts, just fast and private tools.
