Privacy and data protection

Privacy Policy for Free Tool Mate

Free Tool Mate provides browser-based developer tools for JSON, XML, SQL, text, encoding, images, calculations, and more. Our tools are designed to process your input locally on your device.

What data we collect

We keep collection small. In short:

  • Tool input stays in your browser. Text, files, images, and calculator values you enter into tools are processed locally. We do not intentionally upload or store that content on our servers.
  • Necessary site data. We store a language preference cookie and a theme choice on your device so the site remembers how you want the pages to look. We also store your cookie-consent choice in local storage.
  • Analytics (optional). If you accept analytics cookies, Google Analytics may collect page views, approximate location derived from IP, device/browser type, and how you move around the site. This helps us see which tools are used.
  • Advertising (optional). If you accept advertising cookies, Google AdSense and related Google services may use cookies and similar tech to show and measure ads. This can include ad identifiers and interaction data.
  • Contact form. If you send a message, we receive the name, email, subject, topic, and message you submit so we can reply.
  • Server logs. Like most websites, our host may keep standard request logs (IP address, URL, user agent, time) for security and reliability. These are not used to rebuild your tool input.

How your data stays on your local machine

When a tool supports local processing, your text, code, token, image, or other input is handled by JavaScript in your web browser. The result is calculated on your computer or mobile device instead of being uploaded to a remote database. This means sensitive development data can remain in your browser while you format, compare, convert, validate, or calculate.

Free Tool Mate does not intentionally store tool input, tool output, uploaded images, or generated results on our server. Closing the page or clearing the form removes the active working data from the tool interface. Your browser may still keep its own history, cache, or local browser data according to your browser settings.

We use cookies and local storage in these categories. Optional analytics and advertising stay off until you allow them below. For a full breakdown of each cookie, see the Cookie policy.

  • Necessary cookies cover language, theme, and your consent record. These keep the site usable and remember your choices.
  • Analytics cookies are Google Analytics cookies used when you opt in, so we can understand traffic and popular tools.
  • Advertising cookies are Google AdSense cookies used when you opt in, so ads can be shown and measured. Google may also show its own consent message in regions where that is required.

Rejecting optional cookies does not block the tools; pages still work with necessary storage only.

How the online tools work

Each tool page combines a simple interface with browser-side code for a specific task. For example, the JSON formatter parses and formats JSON, the Base64 encoder converts text locally, image tools use browser capabilities to process images, and calculators perform calculations from the values you enter. The exact behavior and supported formats are described on each tool page.

Some pages may load static website files such as CSS, JavaScript libraries, and fonts. These files support the interface and functionality; they are not a copy of the data you enter into a tool.

What you should avoid entering

Although these tools are built for local processing, do not paste passwords, private keys, production credentials, personal health information, or other highly sensitive data unless you understand the risks of using any web browser. Always verify results before using them in production systems.

Language

The site may choose a default language from the country of your IP address when that country matches a language we already offer. The lookup stays on this server. You can change the language in the header dropdown; that choice is stored in a cookie on your device and overrides the automatic default.

Third-party services and links

The website may use static third-party assets, such as Bootstrap or web fonts, to display the interface. External services may process standard browser requests such as your IP address according to their own policies. This site does not sell your tool input or create user accounts for these tools.

When analytics or advertising is enabled by your choice, Google receives the related measurement or ad data under Google's policies. Review Google's privacy materials if you want detail on how Google processes that information.

Advertising consent

Where required, Google's certified Consent Management Platform may also ask visitors in the European Economic Area, the United Kingdom, and Switzerland about advertising cookies. On this Privacy page you can Accept all, Reject optional cookies, or save Analytics and Advertising separately. Your choice is stored in your browser and can be changed anytime from Cookie settings in the footer (this section).

Contact form

The Contact Us page is the one exception to local-only processing. When you submit that form, the name, email, subject, topic, and message you enter are emailed to admin@freetoolmate.com so we can reply. We do not use the form to upload files, and we do not store tool input from JSON, PDF, image, or other utilities. Do not include passwords, private keys, or confidential documents in a contact message.

Privacy questions

If the implementation of a specific tool changes, its page should be updated to explain that behavior clearly. For the most accurate information, read the privacy note shown beneath the tool you are using. You can also contact us with a privacy question.
