Information We Collect

EstiNest is designed with privacy in mind. All calculations are performed locally in your browser. We do not store your financial data on our servers.

Local Storage

We use your browser's localStorage to save preferences, scenarios, favorites, and recent calculators. This data never leaves your device.

Analytics

We may use anonymous analytics to understand how our calculators are used and improve the service. No personally identifiable information is collected.

Cookies

We use minimal cookies for essential site functionality. Third-party ad providers (such as Google AdSense) may set their own cookies.

Advertising

EstiNest displays advertisements through third-party ad networks. These providers may use cookies and similar technologies to serve relevant ads. You can manage ad preferences through your browser settings.

Affiliate Links

Some pages contain affiliate links to financial products and services. We may earn a commission when you click on these links or make a purchase. This does not affect our recommendations or calculator results.

Data Security

Since all calculations happen in your browser, your financial data is never transmitted to our servers. We use HTTPS encryption for all page loads.

Children's Privacy

EstiNest is not intended for children under 13. We do not knowingly collect information from children.

We may update this privacy policy from time to time. Changes will be posted on this page with an updated date.
