Privacy Policy

Last updated: September 24, 2026

PlainCalc (“we”, “the site”) provides free calculator pages. This policy explains what information may be processed when you use https://plaincalc.pages.dev (or a custom domain pointing to the same project).

Information we do not collect by default

Calculator inputs are processed in your browser. We do not operate a user accounts database for v1. We do not ask for your name, email, or payment details to use the tools.

Local storage

Some pages may store recent inputs or UI preferences (such as dismissing a mobile ad slot) in your browser’s localStorage or sessionStorage. This data stays on your device and can be cleared via browser settings.

Hosting logs

Our host (Cloudflare Pages / Cloudflare network) may automatically process technical data such as IP address, user agent, and request timestamps for security, reliability, and analytics inherent to CDN delivery. We do not control Cloudflare’s raw edge logs beyond standard dashboard access.

Advertising

The site includes labeled ad placeholder slots. If Google AdSense or another ad network is enabled later, that network may use cookies or similar technologies to serve and measure ads, including personalized ads where permitted. Google’s policies and tools (including consent messaging where required) will apply. You can learn more in Google’s advertising privacy materials and use browser controls / opt-outs available in your region (for example, Google Ad Settings).

Analytics

We collect anonymous first-party traffic counts only: the page path and which site was visited (no cookies, no fingerprinting, no personal identifiers). Counts are stored on our Cloudflare Worker for operator reporting. We do not sell this data. Cloudflare’s CDN may still process standard request logs separately for security and reliability. If a cookie-based analytics product is added later, this policy will be updated to name it.

Children

PlainCalc is not directed at children under 13. We do not knowingly collect personal information from children.

External links

Tools may link to Etsy, Amazon, government, or utility resources. Their privacy practices are their own.

Changes

We may update this policy as the product or monetization changes. The “Last updated” date will change accordingly.
