Everything you need to know about our static platform
How does ToolSphere process my files without a server?
ToolSphere leverages modern client-side browser technologies including WebAssembly, HTML5 Canvas, the Web Cryptography API, and local JavaScript libraries (like PDF-lib). When you select a file or perform a calculation, everything executes directly inside your browser’s volatile memory on your own computer.
Are there any hidden subscription costs or usage limits?
No. ToolSphere is 100% free with no account registrations, paywalls, or artificial rate limits.
Will my uploaded files or text inputs be saved on your servers?
Never. ToolSphere is hosted as a completely static website on Cloudflare Pages without any backend servers, databases, or Cloudflare Workers. Your documents, photos, passwords, and sensitive financial inputs never leave your device.
