Knittster is built as a lightweight calculator site. The calculator values you enter stay in your browser, and the site does not use accounts, logins, or a user database.
Calculator Data
Knittster's calculators run entirely in your browser. The numbers you enter into a calculator (gauge, measurements, yarn weights, etc.) are never sent to a server, stored, or associated with you in any way.
Native Sharing
Some pages include Share and Copy link buttons. They use your browser's native share sheet or clipboard and do not load social media widgets, create tracking links, or send calculator values to Knittster. Copy link copies only the page URL. If a Share or Copy link action succeeds, GoatCounter records an aggregate event for the action and page, without calculator inputs, calculator results, share text, copied URLs, or destination apps. If you choose to share a visible calculator result, the app or service you select in your browser's share sheet receives the text you chose to share.
Analytics
We use GoatCounter, a privacy-friendly analytics service that does not use cookies and does not collect or store personally identifiable information. It reports aggregate traffic patterns such as which pages are visited, referrers, devices, and general geographic region.
Affiliate Links
Some calculator pages include curated product links to Amazon. If affiliate tracking is active and you buy through one of those links, Knittster may earn a commission from qualifying purchases at no extra cost to you. Amazon may receive information such as the page you came from and the product or search page you visit.
