Privacy Policy

This policy describes what information The Grind Calc (https://thegrindcalc.com) collects when you use the site, and how it is handled. The short version: this is a static calculator site with no accounts, and we collect as little as possible.

Information we do not collect

• No accounts, sign-ups, or passwords.
• No names, email addresses, or other personal details are requested to use the tools.
• Calculator inputs (coffee amounts, water amounts, ratios) are processed entirely in your browser and are never sent to our servers.

Information stored on your device

If you use the light/dark theme toggle, your preference is saved in your browser’s local storage under the key theme. This value never leaves your device and can be removed by clearing your browser data. We do not set cookies.

Hosting and server logs

This site is served by Cloudflare. Like most web infrastructure providers, Cloudflare may process technical data such as IP addresses and request headers to deliver content and protect against abuse. See the Cloudflare Privacy Policy for details. We do not receive or store personally identifiable visitor logs ourselves.

Analytics

We use Cloudflare Web Analytics to understand aggregate site usage (page views, referrers, and country-level location). It is a privacy-first service: it does not use cookies, does not fingerprint devices, and does not track individuals across sites. We see only anonymous, aggregated statistics.

Advertising

We currently show no advertisements. If we introduce advertising in the future (such as Google AdSense), third-party ad vendors may use cookies or similar technologies to serve ads, and this policy will be updated before that happens.

Third-party links

Pages may link to external websites. We are not responsible for the privacy practices of other sites; review their policies separately.

Children’s privacy

This site does not knowingly collect any personal information from anyone, including children under 13.

Changes to this policy

If this policy changes, the updated version will be published on this page with a new effective date.
