Privacy Policy

This page explains what happens to your data when you use StitchHow.

The calculators

Nothing you type into a calculator — gauge, area, yarn weight, or anything else — ever leaves your device. The math happens locally in your browser, with no server round-trip involved, so there's nothing to store, log, or lose. Close the tab and it's gone.

Analytics

Like most websites, we use standard, privacy-respecting analytics to understand which pages get used, in aggregate, so we can prioritize what to build or fix next. This does not include anything you type into a calculator.

Advertising

StitchHow shows display ads through Google AdSense, which helps keep the calculators and the stitch, yarn and sizing reference free. Google and its advertising partners use cookies to serve and measure those ads, and depending on your ad settings the ads may be personalized — including remarketing — based on your visits to this site and to other websites. If you are in the EEA or the UK, Google asks for your consent before setting personalized-advertising cookies, and you can change that choice at any time.

No calculation, pattern note or yarn recommendation here is shaped by an advertiser, and advertisers never see a page before it is published. Some pages also link to products on Amazon as an affiliate, as the affiliate disclosure explains.

To see why an ad appeared or to turn off ad personalization, visit Google My Ad Center; to opt out of interest-based ads from many companies at once, use aboutads.info. How Google uses information from sites that show its ads is set out in Google's own policy.

Contact and payment information

If you contact us through the contact form, we receive whatever you choose to include in your message. If you make a purchase or donation, payment is processed by our payment provider directly — we do not receive or store your full card details ourselves.

Changes to this policy

Meaningful changes to this policy will always be reflected in the "updated" date above — check there if you're wondering whether anything's changed since you last read it.
