Privacy policy
Last updated 2026-10-10. Plain-language summary first, details after.
In short: the numbers you convert stay in your browser. We do not ask you to create an account. If advertising or analytics are enabled on the site, third parties may set cookies as described below.
Information you enter
Amounts, payee names, account numbers and other values you type into the tools are processed locally in your browser. They are not transmitted to our servers.
Information stored on your device
When you use the Save buttons, or change settings such as theme, number system or currency, the site stores them in your browser’s local storage under keys that begin with “ainw_”. You can remove them at any time from the history page or by clearing site data in your browser.
Exchange rates
The currency converter requests exchange rates from a public rate service directly from your browser. That service may receive your IP address as part of the request, as any website does.
Cookies, analytics and advertising
The site may use Google Analytics or similar tools to count visits and Google AdSense or similar partners to show ads. These providers may use cookies or similar technologies to measure usage and to show personalised or non-personalised ads. You can control ad personalisation in Google’s ad settings and manage cookies in your browser. Where the law requires it, we ask for your consent first.
Fonts
Fonts are loaded from Google Fonts, which means your browser contacts Google’s servers when a page loads.
Children
The site is not directed at children under 13 and does not knowingly collect their personal information.
Changes
If we change this policy we will update the date above.
