Privacy Policy
Last updated: 4 October 2026
Introduction
This Privacy Policy explains how InflationMultiplier.com ("this site", "we", "us") handles information when you use this website. It applies to all visitors and users of inflationmultiplier.com.
The short version: this site collects very little data. The calculator runs entirely in your browser, no account is required, and no personal information is collected by us in the course of normal site use.
Data We Collect
We do not collect personal data through normal use of this site. Specifically:
- The inflation calculator runs entirely in your browser using JavaScript. Your inputs (principal amount, interest rate, years, etc.) are never sent to our servers.
- When inflation data is fetched from the World Bank API, the request is made from your browser directly to the World Bank's servers (
api.worldbank.org). Your IP address reaches the World Bank servers, not ours, as part of that API call. - We do not collect your name, email address, or any other personally identifying information โ unless you voluntarily email us at indyragie@gmail.com, in which case your email address is retained only to reply to your message.
- We do not process payments and have no payment or billing data.
- We do not require account registration or login of any kind.
Browser localStorage is used to save two preferences locally on your device:
- Your selected colour theme (dark or light mode)
- Your most recently selected currency
This data is stored only in your browser and never transmitted to any server. It has no expiry and remains until you clear your browser storage.
Google Analytics and Advertising
This site uses Google AdSense to display advertisements. Google AdSense is operated by Google LLC. Google may use cookies, including the DoubleClick cookie, 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 interests derived from visits to this and other sites.
- You can opt out of personalised advertising by visiting adssettings.google.com.
- You can also opt out of third-party vendor cookies via the Network Advertising Initiative opt-out page.
Google's full privacy policy is available at policies.google.com/privacy.
This site may also use Google Analytics or a similar service to measure aggregate site traffic โ for example, which pages are most visited and how users navigate between them. This data is used only to improve the site and is not linked to any individual's identity.
Cookies
This site itself does not set HTTP cookies. However:
- localStorage (not technically a cookie, but similar in purpose) is used to save your theme and currency preferences. This data lives entirely in your browser.
- Google AdSense may set cookies in your browser for the purpose of ad personalisation and frequency capping. These are Google's cookies, not ours. You can manage them through your browser settings or via Google's ad settings.
- If Google Analytics is active on this site, it may set cookies to distinguish visitors and track sessions. These are anonymised and aggregate in nature.
To clear localStorage or manage cookies, use your browser's built-in developer tools or privacy settings.
Third-Party Services
This site interacts with the following third-party services. Each has its own privacy policy.
- World Bank Open Data API (
api.worldbank.org) โ provides inflation and CPI data. Requests are made client-side from your browser. See the World Bank Privacy Notice. - Google AdSense (
pagead2.googlesyndication.com) โ displays advertisements. See Google's Privacy Policy. - Chart.js (
cdn.jsdelivr.net) โ a JavaScript charting library loaded to render the growth chart. jsDelivr's privacy policy is available at jsdelivr.com.
Your Rights
Because we collect no personal data through normal site use, there is nothing stored on our servers to delete, export, or correct on your behalf.
- To clear your saved theme and currency preferences, clear your browser's localStorage for this site using your browser's developer tools (usually under Application > Local Storage).
- To manage or opt out of Google advertising cookies, visit adssettings.google.com.
- If you have contacted us by email and wish to have your email address removed from our records, simply ask and we will do so.
If you are located in the European Economic Area (EEA) and believe you have rights under the GDPR that apply to this site's processing of your data, please contact us and we will do our best to assist.

Changes to This Policy
This Privacy Policy may be updated from time to time to reflect changes in the site's functionality, third-party services used, or applicable law. When updated, the "Last updated" date at the top of this page will change. Continued use of the site after any changes constitutes acceptance of the revised policy.
