Privacy Policy

This Privacy Policy outlines how freetoolbd collects, uses, and safeguards information when you visit and interact with our website.

Local Browser Storage (Zero Server Tracking)

Our calculators utilize browser localStorage exclusively to retain your workflow preferences (such as language selection, custom labels, and active note denominations) between sessions. This data never leaves your personal device and can be cleared at any time via the Reset button or by clearing your browser cache.

Google AdSense & Third-Party Advertising

We partner with Google AdSense to serve contextual and personalized advertisements that keep our service 100% free. Google uses cookies, such as the DoubleClick DART cookie, to serve relevant ads based on visits to this and other websites across the internet. You may opt out of personalized advertising by visiting Google Ads Settings (https://adssettings.google.com/) or via the Network Advertising Initiative (http://www.aboutads.info/choices/).

Cookies and Web Beacons

Third-party advertising partners and analytics vendors may deploy cookies and web beacons to gauge campaign efficacy and prevent invalid traffic. We do not store or collect personally identifiable information (PII) such as your name, email, or financial records during routine tool usage.

Server Log & PDF Export Processing

When you choose to generate and download a note calculation PDF, only the specific denomination data necessary to compile the A4 document is transmitted to our backend rendering microservice. This ephemeral payload is processed in-memory and is discarded immediately after the binary file is delivered.

GDPR & CCPA Rights

Users in the European Economic Area (EEA), the United Kingdom, and California enjoy rights to data transparency, objection to automated profiling, and cookie consent withdrawal. You can manage or revoke cookie consents through our on-site banner or your browser security preferences.

Policy Updates

We reserve the right to periodically update this policy to reflect regulatory changes or new service features. The latest revision date is always reflected at the top of this documentation.
