Last updated: 2026-05-03

Introduction

This privacy notice explains how yarn-substitution-finder.hub2.day (“YarnSwap: Substitution Finder”, “the site”, or “we”) handles information when you use our yarn substitution utility. The site is a focused, independent web tool for knitters and crocheters. We aim to be clear, practical, and respectful of your privacy.

Information We Collect

We collect only what is needed to operate the site and improve its reliability:

  • Browser-local project inputs: Yarn names, weights, fiber content, gauge, and yardage you enter are processed in your browser to generate substitution suggestions. These inputs are not sent to our servers unless you explicitly use a feature that requires server processing (for example, saving or sharing a project).
  • Contact email: If you email hello@yarn-substitution-finder.hub2.day, we collect your email address and message content to respond to your request.
  • Server and security logs: When you visit the site, our hosting provider may automatically log technical information such as IP address, browser type, operating system, referring URLs, pages viewed, and timestamps. These logs help us detect abuse, diagnose issues, and maintain security.
  • Cookies and local storage: The site may use cookies and browser local storage to remember preferences (for example, units or display options) and to support advertising. See the “Cookies, Advertising, and Consent” section below.

How We Use Information

We use the information described above to:

  • Provide and improve the yarn substitution tool and related features.
  • Respond to your questions and support requests.
  • Monitor for security threats, abuse, and technical errors.
  • Understand general usage patterns (for example, which features are most used) to guide improvements.
  • Serve and measure advertising where enabled.

Security

We implement reasonable technical and organizational measures to protect information against unauthorized access, loss, or misuse. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.

Your information may be processed in countries other than your own, including the United States. By using the site, you acknowledge that your data may be transferred to and processed in these countries, which may have different data protection laws.
