Privacy policy

Calculator data

Every calculation on this site is performed in JavaScript running in your own browser. Deposit amounts, interest rates, terms and any other figure you enter are held in the page's memory for as long as the tab is open and are then discarded.

These values are never transmitted to our servers, never written to a database, never logged, and never shared with third parties. There is no server-side calculation endpoint for them to be sent to.

What is stored on your device

The site stores one item in your browser's local storage: your light or dark theme preference. It contains no personal information and is removed if you clear site data.

Accounts and personal information

No account is required to use any calculator, and none is offered. We do not ask for your name, email address, phone number or financial details as a condition of using the tools.

If you email us voluntarily, we hold that correspondence only for as long as needed to respond and to act on any correction it reports.

Analytics and cookies

If aggregate, privacy-respecting analytics are used, they record page-level traffic only — which pages are visited and from where. They never capture the values entered into a calculator, and they do not build a profile of you across other sites.

No advertising cookies or third-party tracking pixels are used.

Third-party services

The site is served through a content delivery network, which necessarily processes your IP address to deliver the page, as any web host does. We do not sell, rent or share visitor data with anyone.

Your rights

Because we do not collect personal data through the calculators, there is generally nothing held about you to access, correct or erase. If you have emailed us and would like that correspondence deleted, write to us and we will remove it.

Changes and contact

If this policy changes materially, the revision date shown below will be updated. Questions about privacy can be sent to hello@cdcalculator.com.
