Frequently Asked Questions

Common questions about parsing integrity, privacy, and technical operations.

Are my files uploaded to a remote server when using Keyword Density Checker?▼
Absolutely not. ToolXHub operates on an offline-first architecture. When you use Keyword Density Checker, all file parsing, cropping, and processing occur 100% locally inside your browser's sandboxed memory using advanced HTML5 Canvas APIs. None of your private photos, signatures, or datasets are ever uploaded to any cloud database, guaranteeing complete data privacy.
Are the passwords, UUIDs, or parsed payloads safe from snooping?▼
Yes, completely. Our developer utilities run fully sandbox-isolated. Generated elements (like passwords and bulk UUIDs) utilize the browser's native cryptographically-secure random number generator (window.crypto), rather than simple math functions. Formatted or minified JSON/YAML/SQL structures are processed purely in local variables and are never transmitted over the internet.
Can I use Keyword Density Checker when I have no active internet connection?▼
Yes, 100%. Once you load ToolXHub in your web browser, all required scripts and modules are cached in your browser. You can safely disconnect from Wi-Fi or turn on Airplane mode; Keyword Density Checker will remain completely functional for processing, converting, or formatting your data offline.
Are there any file size or conversion limit caps on ToolXHub?▼
Unlike competing cloud products, we do not impose any monthly subscriptions, waiting queues, or daily upload limits. You can process as many files as you want. The only hardware constraint is your local device's memory capacity; we recommend processing files under 15MB each for the smoothest experience on mobile browsers.
