Privacy Policy

How How Long Will It Last? handles calculator inputs, analytics, advertising, sharing, and contact information.

Calculator amounts and usage details are normally processed in your browser and are not saved to an account.

Calculator inputs

The service has no login feature and does not store calculator conditions on a server or in localStorage. Specific inputs and calculated values are not sent to GA4.

Analytics

We use Google Analytics 4 to understand and improve the service. We may record page views and actions such as calculate, reset, calculator link, language switch, share, and contact link clicks without calculator values.

Advertising and cookies

Google AdSense and other advertising providers may use cookies or similar technologies for delivery, measurement, and fraud prevention. You can manage cookies through your browser settings.

Social sharing

Share controls send only the page title and URL. Your calculator inputs and results are not added to shared URLs.

Contact

Information you choose to send—such as your name, email address, and message—is used to reply, investigate problems, and improve the service. It is not shared for unrelated purposes except when required by law.

Updates and questions

We may revise this policy when necessary. Use the Contact page if you have questions.
