Privacy Policy

Last updated: November 3, 2025

Data Collection

SizeGuide operates with a privacy-first approach. We do not collect, store, or transmit any personal data to our servers.

Local Storage Only

All size calculations, conversions, and any saved measurements are stored locally in your browser using localStorage. This data never leaves your device and is completely under your control.

No User Accounts

We do not require user registration, authentication, or accounts. You can use all features of SizeGuide anonymously.

Analytics

We use Ahrefs Web Analytics to understand how visitors use our site. This analytics service is privacy-focused and does not track individual users across websites.

Third-Party Links

Our site contains links to partner websites. We are not responsible for the privacy practices of these external sites.

Your Control

You can clear all locally stored data at any time by clearing your browser's localStorage or using the "Clear History" feature in our Size History tool.
