Plain-language summary

What information we collect

Information we don't collect: name, email, phone number, mailing address, payment information, social security number, date of birth, vehicle VIN, license plate, or any other personally identifiable information (PII).

Information we do collect (anonymously, via Google Analytics): approximate location (country/state/city), device type, browser, referrer URL, pages viewed, and time on site. This data is aggregated and not tied to any individual.

Information stored in your browser: the calculator may store your last calculation in localStorage so the page remembers your inputs on return visits. This stays on your device — we never see it.

Cookies

We use the following categories of cookies:

You can opt out of advertising cookies via Google Ad Settings or by browsing in incognito mode.

Third-party services

Your rights under GDPR (EU / EEA visitors)

Because this site does not collect your name, email, address, or any other personally identifiable information directly, most of these rights are satisfied by default — there is nothing on our servers tied to you to access, rectify, or erase. We list the named rights anyway so you know what GDPR guarantees you, and so you can exercise them against our third-party partners (Google, affiliate networks) where applicable:

Your rights under CCPA (California residents)

Same caveat — we don't collect personally identifiable information about you directly, so most CCPA rights are inherently satisfied. The named rights guaranteed by California law are:

Anchor: Do Not Sell or Share My Personal Information. We don't sell or share. The opt-out of behavioral advertising cookies is honored through GPC (below) and Google Ad Settings.

Global Privacy Control (GPC)

We honor the Global Privacy Control browser signal as a valid request to opt-out of the sale or sharing of personal information for California residents under CCPA. When the GPC header is detected on your request, we treat your visit as having exercised your opt-out right; no separate request needed.

Technically, what this means on a faceless AdSense + affiliate site: we don't collect personal data ourselves to honor a GPC against. The signal is honored downstream — Google AdSense's IAB TCF integration and our affiliate-link infrastructure both observe browser GPC signals, so a visitor with GPC enabled receives non-personalized ads and unattributed affiliate clicks where applicable. For full effect, ensure your browser exposes GPC: enable it in Brave, DuckDuckGo, Firefox (with the privacy.globalprivacycontrol.enabled flag), or via the privacycg.org reference extension.

Children

This site is not directed to children under 13. We do not knowingly collect information from children.

Changes to this policy

We may update this policy occasionally. The "last updated" date at the top will reflect any change. Material changes will be flagged in a banner.

Why there is no "contact us" address

This is a faceless informational site. No collection happens directly: no name, email, phone, address, payment, or account. Because there is no personal data on our side to access, rectify, port, or delete, no inbound contact channel is needed for data-subject requests. For data held by our partners (Google AdSense, Google Analytics, affiliate networks: CJ Affiliate, ShareASale, Impact, FlexOffers, MaxBounty), exercise your GDPR / CCPA / GPC rights directly through their privacy policies linked above — they hold the records.
