Everything you need to know about our privacy-first tools, calculation models, licensing, and client-side architecture.
How our zero-trust, client-side architecture safeguards your private information.
Never. Every functional tool on ToolsHub Pro executes 100% locally in your web browser using client-side JavaScript and the Web Cryptography API. Not a single character, formula, or uploaded text block is ever transmitted over the network or saved to our servers.
Yes. Because tools like the JWT Decoder, JSON Formatter, and Diff Checker process everything strictly within your browser's local memory space, your sensitive authorization tokens, proprietary code, and internal payloads remain entirely on your local machine.
No. We do not sell user data or deploy intrusive user tracking cookies. Your session preferences (such as dark mode and recent tool history) are saved strictly on your own device using browser localStorage.
Clarity on tool costs, licenses, and usage rights for personal and commercial work.
Yes! All our client-side calculators, text tools, and developer utilities are completely free. There are no paywalls, hidden tiers, or required account registrations.
Yes. Any result, calculation, vector QR code, or cleaned text generated by ToolsHub Pro belongs entirely to you. You are free to use them in commercial client deliverables, published books, software applications, or marketing materials.
No. Our commitment is that all client-side core utilities will always remain free, open, and fast. Any future enterprise capabilities will be strictly optional and non-intrusive.
Details on precision, banking amortization standards, and measurement scales.
Our financial tools use official retail banking formulas (including the reducing balance amortization equation and high-precision floating-point safeguards) to ensure calculations match real banking statements down to the cent.
The Unit Converter is built using authoritative metric (SI) and imperial definitions established by the International Bureau of Weights and Measures (BIPM) and the National Institute of Standards and Technology (NIST).
Our CGPA Calculator supports both the standard North American 4.0 GPA scale and the international 10.0 scale, with customized credit-weighted averages and percentage conversion multipliers.
Features designed to make your daily workflow faster and accessible anywhere.
Yes. Every tool interface is fully responsive, optimized for touch targets, and designed to perform flawlessly across modern iOS and Android smartphones and tablets.
Yes! Press '?' anywhere on the site to open the keyboard shortcut cheatsheet. You can press '/' to focus the search bar, 'g h' to jump home, 'g t' for tools, and 'Esc' to dismiss dialogs.
Your recently used tools list is stored locally on your device in your browser's localStorage. You can clear your recent history at any time with a single click.
Information about our 30 Days 30 AI Projects technical preview.
Our AI tools are part of the '30 Days 30 AI Projects' engineering initiative. They are currently in Technical Beta Preview, where you can inspect architectural specifications, review typed Zod JSON schemas, and join early access waitlists.
We love feedback! You can reach our engineering team anytime via our Contact Form or open an issue on our GitHub repository.
