Privacy Policy

Last updated: 2026-05-06. This is a generic template — review with a qualified lawyer for your jurisdiction.

Plain-English summary

• Calculator inputs run entirely in your browser and never leave your device.
• We use cookieless Cloudflare Web Analytics — no personal identifiers, no cross-site tracking.
• If/when Google AdSense is enabled, third-party advertising cookies may be set per Google’s policies.
• The only contact channel is a mailto: link to [email protected]; we do not run any submission form.

What we collect

Aggregate analytics: visit counts, page views, country-level location, and browser type, collected by Cloudflare Web Analytics without setting cookies or storing IP addresses persistently.

Email correspondence: when you email us at [email protected], your message and email address arrive in our inbox. We retain it only as long as we need to respond.

Calculator data: none. All math runs in your browser; we have no servers that see your numbers.

Cookies

We do not set first-party tracking cookies. Strictly necessary cookies may be set by a future cookie banner if and only if we activate features that require them.

Advertising

We may serve ads through Google AdSense after publisher approval. Google may use cookies and device identifiers to serve relevant ads. You can manage your ad preferences at adssettings.google.com.

Children

The site is not directed to children under 13 (or the equivalent minimum in your country). We do not knowingly collect data from children.

Your rights

Depending on your location (GDPR, CCPA, etc.), you may have rights to access, correct, or delete personal data we hold about you. Email [email protected] and we will respond within 30 days.

Changes

Material changes to this policy will be posted here with an updated date.
