Question 1

Are my files uploaded to your server?

Accepted Answer

No, absolutely not. All tools on CodingTool.dev run entirely in your browser using JavaScript. Your data never leaves your device, is never uploaded to our servers, and remains completely private. This client-side architecture ensures maximum privacy and security for your sensitive data.

Question 2

Is CodingTool.dev free to use?

Accepted Answer

Yes, CodingTool.dev is completely free to use. All 35+ developer tools are available without any registration, subscription, or payment. We support the platform through non-intrusive advertisements, which allow us to keep the service free and accessible to developers worldwide.

Question 3

Can I use these tools offline?

Accepted Answer

Some tools may work offline if your browser has cached the necessary files. However, the initial page load requires an internet connection. For full offline functionality, we are planning to release browser extensions and desktop applications in the future.

Question 4

Do I need to create an account?

Accepted Answer

No account or registration is required. Simply visit CodingTool.dev and start using any tool immediately. Your preferences (like theme and language) and tool history are saved locally in your browser using localStorage, so you can access them across sessions without logging in.

Question 5

How do I access tools quickly?

Accepted Answer

Use the command palette! Press Ctrl+K (Windows/Linux) or Cmd+K (Mac) anywhere on the site to open a quick search dialog. Type the name of any tool and press Enter to navigate instantly. You can also use the sidebar menu or search from the homepage.

Question 6

What languages are supported?

Accepted Answer

CodingTool.dev is available in 6 languages: English, Indonesian (Bahasa Indonesia), Chinese (Simplified), Chinese (Traditional/Taiwan), Japanese, and Russian. The site automatically detects your browser language, or you can manually select your preferred language from the language switcher in the header.

Question 7

Do you store my tool history?

Accepted Answer

Tool history is stored locally in your browser using localStorage, not on our servers. This means your history is private to your device and browser. You can clear your history at any time using the clear button in each tool, or by clearing your browser data.

Question 8

How accurate are the tools?

Accepted Answer

We strive for high accuracy, but as with any software, there may be edge cases or bugs. Our tools are thoroughly tested, but they are provided "as is" without warranties. For mission-critical or production use, always verify outputs independently. If you find any issues, please report them so we can fix them quickly.

Question 9

Can I contribute or suggest new tools?

Accepted Answer

Yes! We welcome feature requests and contributions. You can contact us through the contact page with your suggestions. If you are a developer, you can also check our GitHub repository (coming soon) to contribute code or report issues.

Question 10

What browsers are supported?

Accepted Answer

CodingTool.dev works on all modern browsers including Google Chrome, Mozilla Firefox, Safari, Microsoft Edge, and Brave. We recommend using the latest version of your browser for the best experience. Internet Explorer is not supported.

Question 11

Does the site work on mobile devices?

Accepted Answer

Yes! CodingTool.dev is fully responsive and optimized for mobile phones and tablets. All tools are accessible and functional on smaller screens, though some complex tools (like code editors) may be more comfortable to use on desktop.

Question 12

How is my privacy protected?

Accepted Answer

Your privacy is our top priority. Since all tools run in your browser, we never see or store your data. We only collect anonymous analytics (via Google Analytics) to understand which tools are popular and how to improve the site. You can read our full Privacy Policy for more details.

Question 13

Why do I see advertisements?

Accepted Answer

Advertisements (via Google AdSense) help us keep CodingTool.dev free for everyone. We carefully place ads to be non-intrusive and not interfere with your workflow. We do not show pop-ups or video ads. If you use an ad blocker, the site will still work perfectly—we just ask that you consider supporting us by allowing ads.

Question 14

Can I bookmark or save favorite tools?

Accepted Answer

Yes! You can bookmark tools directly in your browser (Ctrl+D / Cmd+D), or use the bookmark feature on our homepage. We are also working on a favorites system that will save your preferred tools locally for quick access.
