Privacy policy.
The short version: the converters run entirely in your browser and the numbers you type are never sent to us or stored. We do use analytics and advertising services, described in full below. Last updated June 2026.
What we collect directly
Nothing you enter into a converter leaves your device. Conversions are performed by JavaScript in your browser; the amounts you type, paste, or upload (including CSV files in the bulk tool) are processed locally and never transmitted to a server or saved by us. We do not run user accounts and do not ask for personal information to use the tools.
Third-party services we use
Like most free, ad-supported sites, we rely on third-party services for measurement and advertising. These services may set cookies or use similar technologies, and may process limited technical data such as your IP address, device and browser type, and pages viewed. Each service is governed by its own privacy policy.
Google Analytics (GA4)
We use Google Analytics 4 to understand which pages are used and how the site performs, in aggregate. It helps us decide what to improve. Analytics storage is governed by the consent choice described below, and we operate Google Consent Mode v2 so that, before consent, measurement runs in a restricted, non-identifying way. Google's handling of this data is described in the Google Privacy Policy.
Google AdSense
We display advertising through Google AdSense to fund the site. Google and its partners may use cookies to serve ads and, where you have consented, to personalise them based on your prior visits to this and other sites. Without consent, ads are served in a non-personalised manner. You can review and adjust Google's ad settings at Google Ads Settings, and read more in the Google Advertising policy.
Adsterra
We also use Adsterra as an advertising network. Adsterra may set cookies and process technical data to deliver and measure advertisements. Its data practices are described in the Adsterra Privacy Policy.
Cookies & your consent
If you visit from the EU, EEA, UK, Switzerland, or California, you'll see a consent banner before non-essential cookies are set. You can accept or decline analytics and personalised advertising; declining keeps the tools fully usable, with advertising and measurement running in a restricted, non-personalised mode. You can change your choice at any time by clearing this site's cookies in your browser and reloading the page.
In regions where a banner isn't shown, you can still control cookies through your browser settings and the Google ad-settings link above.
Your rights
Depending on where you live, you may have rights to access, correct, or delete personal data, or to object to certain processing. Because we don't hold accounts or collect data that identifies you directly, most requests relate to the third-party services above — their policies explain how to exercise those rights with them. If you have a question for us, use the contact page.
Changes to this policy
We may update this policy as the site or the services it uses change. The "last updated" date at the top reflects the current version.
