1. Introduction and Scope
This Privacy Policy outlines the data processing practices of Pro Calculator (“we”, “us”, “our”, “the Website”), accessible via the domain https://procalculator.co.uk/.
We are committed to protecting and respecting your privacy in compliance with the UK General Data Protection Regulation (UK GDPR), the Data Protection Act 2018, and the Privacy and Electronic Communications Regulations (PECR). This policy provides a detailed explanation of what data we collect, why we collect it, how it is processed, and your rights relating to your data.

2. Our Core Privacy Principle: No Processing of User-Inputted Data
The fundamental principle of our service is the complete privacy of your interaction with our tools. Any data, figures, text, or variables that you enter into any calculator, converter, or other online tool on this Website (“User-Inputted Data”) are processed exclusively within your local browser environment on your own device.
At no point is User-Inputted Data transmitted to, stored on, logged by, or otherwise processed by our servers. We have no access to, nor any interest in, the content of your calculations. The service is designed to be functionally anonymous by default.
