Privacy and data
Privacy Policy
This policy explains data processing that may occur when you visit alltools.qzz.io. The site does not require an account and has no form for uploading files or submitting personal details.
Effective and last updated: July 14, 2026
1. Values you convert
Standard unit conversions run directly in your browser. Numbers you enter are not saved to a site account or database and are not used to build a user profile.
When you use currency conversion, the page requests public rate data from third-party APIs. The request does not include the amount entered in the converter.
2. Local preferences
The site uses browser localStorage to remember language and theme preferences. This data remains on your device and is not an advertising cookie used for cross-site tracking. You can remove it through your browser’s site-data controls.
- omni_locale: selected interface language
- omni_theme: light, dark, or system theme
3. Network requests and third parties
Hosting or content-delivery services may process standard technical information such as IP address, request time, requested URL, browser type, device information, and referring page to deliver the static site, maintain security, and diagnose failures.
The currency page may connect to ExchangeRate-API, jsDelivr, or Currency API. Like any web request, these services receive the IP address and request headers needed to respond and process them under their own privacy policies. The site does not send the amount you entered to those APIs.
4. Google advertising and cookies
If this site enables Google AdSense or another Google advertising service, Google and its partners may use cookies, web beacons, IP addresses, or other identifiers to serve, measure, and personalize ads. Third-party vendors, including Google, may use cookies to serve ads based on a user’s previous visits to this or other websites.
Google’s use of advertising cookies enables it and its partners to serve ads based on visits to this site and other sites on the Internet. Users can manage or opt out of personalized advertising through Google Ads Settings. Depending on region and advertising configuration, a consent or privacy-choice message may be required before ads are loaded.
5. Sale, retention, and security
This site does not sell personal information. The site itself does not maintain conversion histories or a user-account database; hosting, rate, and advertising providers retain the data they process according to their own policies.
We use HTTPS and a data-minimization approach, but no Internet transmission can be guaranteed absolutely secure.
6. Children, regional rights, and updates
The site is intended for a general audience, is not directed specifically to children, and does not knowingly request children’s personal information. You can control local storage and cookies in your browser and manage Google ad personalization in Ads Settings. Applicable law may also provide rights to access, delete, object to, or restrict processing.
This policy will be updated when features, providers, or legal requirements change. The new date will be shown on this page.
