Privacy Policy

Last updated: November 2026

1. Local in-browser data processing

At Herramix (https://herramixpy.com), your privacy comes first. Every utility on our website (word counter, calculators, JSON formatter, subnet calculator, password generator, image compressor, and image resizer) executes 100% locally inside your web browser using standard JavaScript.

Any text, numbers, passwords, IP addresses, or images you enter into our tools are never uploaded, transmitted, or stored on our servers. All processing takes place in your device's memory and is cleared as soon as you close or refresh the page.

2. Local Storage

We only use your browser's localStorage to save your visual preference between light mode and dark mode (key herramix_tema). This setting contains no personal information and stays exclusively on your device.

3. Cookies, third-party advertising, and analytics

To keep Herramix free of charge, we may display advertisements served by third-party networks such as Google AdSense and use aggregated web analytics to understand which tools are most useful.

• Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites.
• Google's use of advertising cookies enables it and its partners to serve ads to users based on their visit to Herramix and/or other sites on the Internet.
• Analytics services collect anonymous usage statistics (such as device type, browser language, and visited pages) without personally identifying individual visitors.

4. Managing and disabling cookies

You can control, block, or delete cookies at any time through your web browser settings (Chrome, Firefox, Safari, Edge, etc.). You may also opt out of personalized advertising from Google by visiting Google Ads Settings or aboutads.info.
