Privacy Policy
Welcome to CalcuClub. CalcuClub provides online calculators and reference tools for mathematics, physics, chemistry, conversions, and related topics. We respect your privacy and are committed to being transparent about how information is collected and used.
Information Collection
CalcuClub does not require users to create accounts or submit personal information in order to use the website. However, we may automatically collect limited technical and usage information, including IP address, browser type, device information, pages visited, and approximate usage patterns. We may also store calculator preferences locally to improve usability.
If you choose to send feedback through the form on the website, we receive the message you write and, optionally, your name and email address. Together with the message we store the language, the page you sent it from, and the approximate country derived from your connection. We use this data only to understand and improve the website and, if you left an email address, to reply to you. You can request the deletion of your feedback by writing to contact@calcuclub.com.
The website is hosted and delivered through Cloudflare, which processes technical data such as the IP address in order to deliver and protect the site. We use Google Analytics to obtain aggregated usage statistics.
