Privacy policy

The short version: no accounts, no ad tracking, and nothing you type into a calculator ever leaves your device.

What the calculators do with your numbers

Nothing. Every calculator on this site runs entirely in your browser using JavaScript. The amounts, rates and balances you enter are never transmitted to a server, never stored, and are discarded when you close the tab.

Analytics

The site uses Google Analytics via Firebase to count page views and understand which guides are useful. It records technical information such as the page visited, an approximate location derived from your IP address, device type and browser. It is not used to build advertising profiles, and no advertising network runs on this site.

You can block analytics with any standard content blocker or your browser's do-not-track and cookie controls; the site works exactly the same without it.

If you subscribe, your email address is stored so the newsletter can be sent to you. It is not sold, rented or shared, and it is not used for anything other than sending financial education from Biren Finance. Every issue includes an unsubscribe link, and you can ask for removal at any time.

Contact form

Messages you send through the contact form — your name, email address, subject and message — are stored so they can be read and answered. Please do not send account numbers, passwords or other sensitive personal details.

Cookies and local storage

The site sets no advertising cookies. Analytics may set its own cookies or local storage entries to count returning visits. No content on this site is gated behind an account, so there is no login session to store.

Third-party embeds

Video thumbnails are served from this site rather than from YouTube, so no request is made to a video host until you choose to watch. Where a video is embedded, it uses the privacy-enhanced player and only loads once you interact with the page.

Your rights

You can ask what data is held about you, ask for it to be corrected, or ask for it to be deleted, by using the contact form. Requests are handled as promptly as possible.

Changes

If this policy changes materially, the updated version will be published on this page.
