Last updated: July 2026. This explains what data is collected on TallyBench, how third-party advertising works here, and how to control it.
TallyBench's calculators run entirely in your browser. Numbers you type into a calculator — a loan amount, an age, a bill total — are never sent to our servers, stored, or logged anywhere. We don't require an account, an email address, or any sign-up to use any tool on this site.
This site displays ads served by Google AdSense. Google and its advertising partners use cookies to serve ads based on your prior visits to this site and other sites on the internet. This is standard for ad-supported sites and works as follows:
Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to users based on their visits to this site and/or other sites on the internet.
You can opt out of personalized advertising by visiting Google's Ads Settings, or opt out of a third-party vendor's use of cookies for interest-based advertising by visiting aboutads.info.
Beyond the advertising cookies described above, this site does not set its own tracking cookies. If analytics tools are added in the future, this policy will be updated to reflect that, and any such tool will only collect anonymized, aggregate usage data (such as which pages are visited), never anything you type into a calculator.
The Currency Converter fetches live exchange rate data from a third-party API (frankfurter.dev, sourced from the European Central Bank) at the moment you use it. No personal information is sent as part of that request — only the currency codes and amount you've entered, processed in your browser.
This site is not directed at children under 13, and we do not knowingly collect any personal information from children. In line with Google's policies, no targeted advertising is served to users identified as minors.
Depending on where you live, you may have rights to access, correct, or delete personal data held about you, and to opt out of the sale or sharing of personal data for targeted advertising. Since TallyBench itself does not collect or store personal data beyond what's described above, most such requests would be directed to Google regarding their advertising cookies — see the opt-out links above.
This policy may be updated as the site adds new features or as advertising and privacy regulations change. The "last updated" date at the top of this page will reflect the most recent revision.
Questions about this policy or the site can be sent via the contact details on the About page.
