Who We Are

FiberTools (“we,” “us,” “our”) operates the website fibertools.app. We provide free, browser-based calculators and tools for knitters, crocheters, weavers, spinners, and embroiderers.

What We Collect

All FiberTools calculators run entirely in your browser. We do not send your inputs, results, or calculations to any server. Here is what we do collect:

Analytics (Google Analytics 4): We use GA4 to understand how people use the site — which pages are visited, how long sessions last, and general geographic region. GA4 uses first-party cookies. We have IP anonymization enabled. No personally identifiable information is collected through analytics.

Advertising (Google AdSense): If and when ads are displayed, Google AdSense may use cookies to serve ads based on your prior visits to this or other websites. You can opt out of personalized advertising at Google Ad Settings.

Local Storage: Some tools save your preferences (such as unit toggle between yards and meters) in your browser's localStorage. This data never leaves your device.

Cookies

We use cookies for analytics and advertising. For full details, see our Cookie Policy. You can manage your cookie preferences at any time through the cookie consent banner or your browser settings.

How We Use Your Information

We use the limited data we collect to:

  • Understand which tools are most popular so we can improve them
  • Monitor site performance and fix errors
  • Display relevant advertising to support the free service

We do not sell, rent, or share your personal information with third parties for their own marketing purposes.

Third-Party Services

We use the following third-party services:

Your Rights

GDPR (EU/EEA/UK users): You have the right to access, correct, delete, or port your personal data. You may also object to or restrict processing. Since we collect minimal data, most of these rights are satisfied by default. Contact us if you have questions.

CCPA (California users): You have the right to know what personal information we collect, to request deletion, and to opt out of the sale of personal information. We do not sell personal information. See our Do Not Sell My Personal Information page.

Children's Privacy

FiberTools is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal data, please contact us and we will delete it.

Data Retention

Analytics data is retained according to Google Analytics default settings (14 months). We do not maintain any separate database of user information.

Changes to This Policy

We may update this policy from time to time. Changes will be posted on this page with an updated date. Continued use of the site after changes constitutes acceptance.
