What happens in your browser
All calculations run in the page on your device. The numbers you type stay in the page's memory and disappear when you close or reload it. The site makes no requests of its own to send your inputs anywhere. The “Copy result” button writes text to your clipboard only when you click it.
What our host processes
The site is served by Cloudflare (Workers). To deliver and protect the site, Cloudflare processes request data such as your IP address, user agent, and the URL you request, and may keep logs under its own policy: Cloudflare privacy policy. We do not sell personal data.
Cookies and local storage
The site itself sets no cookies and uses no local storage or session storage. If that changes, this page will say exactly what is stored and why before it happens.
Advertising, if we add it
Ads are not currently shown. If we add advertising in future, Google AdSense may use cookies, including the DoubleClick cookie, to serve ads based on prior visits to this and other sites, and other third-party vendors may use cookies too. You can opt out of personalized advertising at google.com/settings/ads and learn more at policies.google.com/technologies/ads.
Affiliate links
If we add affiliate links in future, this policy will be updated before they appear.
Children
StockingCalc is not directed at children under 13, and we do not knowingly collect information from them.
Changes to this policy
When this policy changes, we will update the effective date at the top of the page. See also about StockingCalc.
