Pawtern is a tool that turns your pet's measurements into a sewing pattern. We designed it to need no account and no personal data.
Nothing personal. The measurements, pet names, photos and patterns you enter stay on your device (in the app) or in your browser (on the website). They are never uploaded to, or stored on, any server we control.
All calculations and PDF files are produced locally on your device / in your browser. Nothing you enter is transmitted.
The website may record anonymous, aggregate event counts (for example, how many times a pattern was downloaded) to understand which features are used. These counts contain no personal information, no IP addresses and no cookies, and they respect your browser's “Do Not Track” setting. The iOS app does not do this.
We do not sell or share any data, because we do not collect any. The website loads a PDF library and is hosted on a content-delivery network; these may see standard, non-identifying request information (as any website host does), which we do not use to identify you.
Pawtern is a general-audience utility and does not knowingly collect data from anyone, including children.
If this policy changes, we will update this page and the “last updated” date above.
