No Data Collection

Subscription Cost Calculator ("SubCost.tools") is a privacy-first tool. All calculations are performed entirely in your browser. We do not collect, store, or transmit any personal information or subscription data to our servers.

Local Storage

Your selected subscriptions are saved in your browser's local storage so they persist between visits. This data never leaves your device and is deleted when you clear your browser data or use the "Clear All" button.

Analytics

We may use Google Analytics to understand how visitors use our site (page views, session duration, etc.). This data is anonymized and aggregated. You can opt out by using a browser extension like uBlock Origin or by enabling "Do Not Track" in your browser settings.

Cookies

We do not use cookies for tracking purposes. If Google Analytics is enabled, it may set cookies as described in Google's Privacy Policy.

Third-Party Services

In the future, we may display advertisements (e.g., Google AdSense). These third parties may use their own cookies and tracking technologies. We will update this policy when ads are introduced.
