1 What Are Cookies?
Cookies are small text files stored on your device when you visit a website. They are widely used to make websites work, improve user experience, and provide information to site owners.
Cookies can be first-party (set by the site you're visiting) or third-party (set by a different domain). They can also be session cookies (deleted when you close your browser) or persistent cookies (stored until they expire or you delete them).
2 Our Approach
Our analytics provider (Plausible) is cookieless by design. The only cookie that may appear on your device from visiting this site is a single functional cookie from Cloudflare, described below.
3 Cookies We Use
The following table lists every cookie associated with this site:
That's the full list. One cookie, functional only, no personal data, expires in 30 minutes.
4 Cookies We Don't Use
To be explicit, this site does not use:
- Google Analytics or any Google tracking cookies
- Facebook Pixel or Meta tracking
- Any advertising or retargeting cookies
- Any cross-site tracking cookies
- Any cookies that store your calculator inputs or results
- Any login session cookies (there is no login)
- Any persistent first-party cookies set by us
5 Third-Party Cookies
This site loads resources from the following third-party domains. While we do not control cookies these services may set, we have listed what we know about each:
6 Managing Cookies
Because we use so few cookies, there is very little to manage. However, you have full control over cookies through your browser settings:
- Chrome: Settings → Privacy and Security → Cookies and other site data
- Firefox: Settings → Privacy & Security → Cookies and Site Data
- Safari: Preferences → Privacy → Manage Website Data
- Edge: Settings → Cookies and site permissions → Manage and delete cookies
You can also block or delete the Cloudflare __cf_bm cookie at any time. Doing so will not affect the calculator's functionality — it only affects Cloudflare's ability to distinguish you from automated bots.
To opt out of Cloudflare's data processing, see Cloudflare's privacy policy.
7 Changes to This Policy
If we add new features that require additional cookies, we will update this policy before deploying them and revise the "Last updated" date at the top of the page.
We commit to keeping this list accurate and up to date. If you notice a discrepancy between this list and the cookies actually present on your device, please contact us.
