Frequently Asked Questions
What is TheToolz?
TheToolz is a comprehensive collection of free, privacy-focused online tools designed to help with a wide range of everyday and professional tasks. Our tools run directly in your browser, meaning your data stays on your device.
Are the tools on TheToolz really free to use?
Yes, all tools on our website are completely free to use. There are no hidden fees, subscriptions, or premium-only features. The project is supported by on-page advertising.
Do I need to create an account or sign up?
No, you do not need to create an account. All our tools are accessible immediately without any registration, providing a quick and hassle-free experience.
Is my data safe when using these tools?
Absolutely. Our core principle is user privacy. All calculations and data processing happen on your device (client-side). We do not send, store, or track any of the data you enter into our tools.
How do you make money if the tools are free?
TheToolz is supported by revenue from Google AdSense advertisements displayed on the pages. This allows us to keep the tools free for everyone while covering our development and maintenance costs.
How can I suggest a new tool?
We love hearing ideas from our users! You can contact us through our contact page to suggest a new tool. We are always looking to expand our collection based on user feedback.
How accurate are the health calculators (BMI, Body Fat, etc.)?
Our health calculators are based on widely accepted and scientifically validated formulas. However, they are intended for informational purposes only and should not replace professional medical advice. Always consult a healthcare provider for medical concerns.
Can I use these tools for commercial purposes?
Yes, you are free to use our tools for both personal and commercial purposes. Whether you are a student, a professional, or just curious, our tools are here to help.
Are the tools available in other languages?
Yes, our website includes a translation feature in the header. You can select your preferred language to translate the content of the site.
Can I download the QR codes and barcodes I generate?
Yes, our QR Code and Barcode generators allow you to download the generated images in high-quality formats suitable for both digital use and printing.
How does the Network Speed Test work?
Our speed test tool downloads and uploads small packets of data from your browser to a nearby server to measure your internet connection's real-time performance, providing you with download speed, upload speed, and latency.
Are the financial data tools (currency, oil prices) real-time?
Our financial tools fetch data from reliable third-party APIs. While the data is updated frequently, there may be a slight delay. Please refer to the timestamp on the respective tool pages for the latest update time.
What is the difference between Professional Text Analysis and a simple word counter?
Our Professional Text Analysis tool goes far beyond basic counting. It provides detailed insights such as readability scores (like Flesch-Kincaid), keyword density, sentence complexity, and estimated reading time to help you improve your writing.
Can I save my results from the tools?
Since we do not store your data, results are not saved to an account. However, many tools offer the ability to copy results to your clipboard or download them as a file (e.g., images, text files).
Why do some tools have a "coming soon" message?
We are constantly developing and expanding our suite of tools. A "coming soon" message indicates that we are actively working on building that tool and it will be released in the near future.
