FREES WEB HUB / Frequently asked questions
Frequently Asked Questions
Answers to common questions regarding local data processing, ad serving, offline usage, and privacy.
Are My Files or Input Data Uploaded to Any Server?
No. Core utilities, including JSON formatters, text cleaners, Base64 converters, regex matchers, and OCR text extractors, execute entirely inside your local browser memory and Web Workers. No raw data, images, passwords, or tokens are sent to any remote server.
Why Does the Website Display Advertisements?
Frees Web Hub is completely free to use. Non-intrusive programmatic advertisements help support continuous hosting bandwidth, edge domain infrastructure, and ongoing open-source development without requiring paid paywalls or user subscription mandates.
Can I Use Frees Web Hub Offline Without an Internet Connection?
Yes. By installing Frees Web Hub as a Progressive Web App (PWA), static assets and Web Worker scripts are cached on your device through Service Workers, allowing you to launch and use essential conversion and calculation tools entirely offline.
How Do I Adjust or Revoke My Privacy and Cookie Preferences?
Click the 'Privacy Preferences' button in the global footer at any time to open the privacy control dialog. From there, you can accept, decline, or revoke analytical and advertising tracking permissions with immediate client-side enforcement.
