The numbers you type
Your calculator inputs never leave your device. Every calculation on this site runs in your browser using JavaScript. Your salary, debts, balances, and interest rates are not transmitted to any server, not stored in any database, and not logged anywhere. Refresh the page and they're gone.
We have no way to see what you enter, even if we wanted to.
Information we collect directly
None. There are no accounts, no sign-up forms, no email capture, and no contact forms on this site.
Information collected by third parties
Although we don't collect data ourselves, some third-party services used to run and fund the site do. These are described below.
Advertising
This site displays advertising, which is what keeps it free. Advertising partners — including Google, if you are served Google AdSense ads — may use cookies and similar technologies to serve ads based on your prior visits to this and other websites.
- Google's use of advertising cookies enables it and its partners to serve ads based on your visits to this site and other sites on the internet.
- You can opt out of personalised advertising by visiting Google Ads Settings.
- You can opt out of some third-party vendors' use of cookies at aboutads.info/choices.
- Third-party vendors and ad networks may also serve ads on this site and use their own cookies.
Analytics
We may use privacy-respecting analytics to understand which calculators are used and how people find the site. This measures pages and traffic sources — never the values you enter into a calculator.
Web fonts
Typefaces are loaded from Google Fonts. When your browser requests them, Google receives your IP address as part of that normal request. See Google's privacy policy for how they handle it.
Hosting
Our hosting provider may keep standard server logs — IP address, browser type, pages requested, timestamps — as is typical for any website, for security and operational purposes.
Cookies and how to control them
The site itself sets no cookies for its own purposes. Cookies you encounter here come from the advertising and analytics services described above.
Every major browser lets you block or delete cookies through its settings. Blocking them will not stop any calculator on this site from working — the tools do not depend on cookies at all.
Your rights
Depending on where you live, you may have rights over personal data held about you, including under the GDPR (Europe/UK) or CCPA (California) — such as the right to access, correct, or delete it, and to object to certain processing.
Because we hold no personal data ourselves, requests of this kind generally need to go to the third parties listed above, who are the parties actually collecting it. Their own privacy policies explain how to do that.
Children
This site is not directed at children under 13 and we do not knowingly collect information from them.
Changes to this policy
If this policy changes, the "last updated" date above will change with it. Material changes will be reflected here rather than announced separately, so it's worth re-reading if you're relying on it.
Contact
For questions about this policy, or to make a request relating to your data, email contact@theledgertools.com.
The Ledger operates exclusively online. Email is the designated method for privacy-related requests — we don't maintain a phone line or postal address for this purpose.
