Privacy Policy
This policy explains what information coolca.lc and its Guide collect and how it's used. The short version: your calculations stay on your device, there are no accounts, and advertising on the site may use cookies, which you can control.
Your calculations stay on your device
The calculator stores your Log, Memory presets, Solver values and settings (such as theme and number format) in your browser's local storage, on your device. This information is not sent to coolca.lc or anyone else. It stays until you clear it, either in the calculator (for example, with Clear in the Log) or by clearing your browser's site data.
When you paste into the calculator, the text is read in your browser to find the numbers, and is not sent anywhere. The calculator only reads your clipboard when you paste or tap the paste button.
coolca.lc has no accounts or sign-in, and doesn't ask for your name, email address or other personal details, except when you choose to send us a message.
Messages you send us
When you use the contact form, we receive what you enter: your email address, your name if you give it, the topic and your message. We use it only to read and reply to your message. It reaches us as an email; if email delivery fails, it's kept on our server until we can read it. We don't add you to any list or share your message with anyone.
To keep spam out, the form runs a short check in your browser before sending, and the server counts recent messages from each network address. Network addresses are stored only as a one-way code that can't be turned back into the address, and these counts are discarded after a day. The form uses no cookies and no third-party services.
Information collected automatically
Like most websites, the server that hosts coolca.lc keeps standard logs of the requests it receives, including the address requested, the date and time, your IP address, and your browser's user agent. These logs are used to operate and secure the site, and are kept for a limited time.
