Privacy & links
Your plan stays with you.
Calculators run in your browser. We count visits with our own cookie-free analytics, and you can switch it off below. Buying links, tools and saved projects work either way. The community area and email sign-ups have their own details below.
Analytics preferences
Our self-hosted Umami service counts pages viewed, clicks on paid Amazon and LoveCrafts links and their position, valid calculator submissions and clicks opening Pinterest. This helps us understand which guides lead to useful shopping links. A Pinterest click is not proof of a save and a shop click is not proof of a purchase.
It also receives browser/device details, language, referrer and approximate location. No calculator inputs or shopping-search text are included. URL query strings and fragments are excluded. It sets no analytics cookies. It is on unless you switch it off. If you do, we store that choice in this browser’s local storage so it applies on every page; clearing browser data turns analytics back on, so switch it off again or use Do Not Track. We honour Do Not Track and Global Privacy Control even if analytics was previously allowed.
Analytics is on unless you switch it off.
Shop-link click count
Separately from analytics, when you click a shop link we count the click: which shop, which part of the page and which page, rounded to the hour. It sets no cookie, reads nothing from your device and stores no IP address or visitor ID, so it cannot tell visitors apart. It runs whether or not analytics is on, because it holds no personal data.
Saving a project
The yarn planner keeps your current list in this browser’s local storage so it is there when you come back. It stays on your device. “Save inputs on this device” stores a separate copy that you choose to keep. Remove it with “Delete saved inputs” or by clearing this site’s browser data. Someone sharing this browser may be able to load it.
Backups and moving between tools
A downloaded project backup is a JSON file on your device. Restoring it reads and checks it locally; it is not uploaded. A restored file replaces the form but does not replace your explicitly saved project until you save it. Moving a list between calculators uses this tab’s session storage; transfers are consumed once and expire after an hour. Product-prefill URLs contain public catalogue identifiers and guide quantities, not private project details.
External links
Shop and source sites have their own privacy policies. Paid links include our merchant affiliate identifiers. Product cards and guide links do not carry your form inputs. The planner’s Amazon basket/search buttons send only the yarn name, shade and ball count you choose to Amazon UK when you click. The optional HazelLoop analytics choice does not control Amazon or another shop after you leave our site.
Hosting, community and contact
HazelLoop is hosted on a private server. The web server keeps no access logs and the site sets no cookies, except one strictly necessary sign-in cookie for designers who use the community area. How we count visits and shop-link clicks is explained under Analytics preferences above. The pattern reader sends the text you paste to Anthropic (Claude AI) to read it; HazelLoop does not store that text, only a count of uses. The “Was this useful?” box stores your vote, any note you type and the page address, without your IP address. Designers who join the community give us their email address (used only to send sign-in links, via the email service Resend, and messages about their patterns), their public profile and their patterns. Shared photos are re-saved without camera data, including location, and new patterns are checked automatically with Anthropic (Claude AI) before they go live. Designers can delete their patterns or close their account at any time. If you ask for our free printable tracker, we keep your email address to send it and occasional planning emails (sent with Resend), only after you confirm by clicking the link we email you. Every email has a one-click unsubscribe link, and we never share or sell your address.
