Privacy policy

The calculator runs in your browser. Here is what that means for your information.

Calculator inputs

The site does not intentionally send calculator entries to an application server or store them in a database. It has no accounts or forms that collect personal details. Calculations happen locally in your browser.

Shareable links and browser history

When you change a valid input, the browser address is updated with readable calculation parameters. Copy link copies that URL to your clipboard. Anyone who receives it can see the initial amount, monthly contribution, annual rate, and duration.

These URLs may appear in browser history, synced browser data, clipboard history, screenshots, and messages. When a shared URL is opened, its query parameters are sent to the hosting infrastructure and may appear in access or security logs. Avoid putting sensitive financial scenarios in links you do not want others to see.

Cookies, storage, and analytics

The application does not set cookies or use local storage to save your entries. It includes no analytics, advertising trackers, or third-party fonts. Hosting providers may process technical information such as IP addresses, request URLs, browser information, and timestamps to deliver and protect the service. Their retention and processing depend on the hosting configuration.

External services

No external financial API is used. The calculator does not retrieve live rates or account information. Copying a link does not send it to a third-party sharing service.
