This Privacy Policy explains what information Onnax Tools ("we", "us") does and β more importantly β does not collect when you use tools.onnax.com (the "Site").
1. Your Files Never Leave Your Device
All 120 tools on this Site process files locally in your web browser using JavaScript. When you use a tool, your file is opened by your own browser, transformed on your own device, and saved back to your own storage. We do not receive, transmit, store, view or back up your files β ever. Our web server only delivers the static pages and scripts that make the tools run.
2. Information We Collect
We collect a minimal amount of information, none of it from your files:
- Usage analytics (aggregate): standard, anonymized statistics such as which pages are visited, browser type, device category, country and referring site. This helps us understand which tools people find useful.
- Server logs: like virtually every website, our hosting provider records IP addresses and requested URLs in short-lived technical logs used for security and troubleshooting.
- Contact messages: if you email us, we receive what you send us.
3. Cookies and Advertising
The Site is supported by advertising. Third-party advertising partners (such as Google AdSense) may use cookies and similar technologies to serve ads, measure ad performance and, where permitted, personalize ads. Specifically:
- Third-party vendors, including Google, use cookies 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 visits to this Site and/or other sites on the Internet.
- You may opt out of personalized advertising by visiting Google Ads Settings, or www.aboutads.info.
See our Cookie Policy for details on managing cookies.
4. Legal Bases (GDPR)
For visitors in the European Economic Area and the UK: we process the limited data above on the basis of legitimate interest (site security, aggregate analytics) and consent (personalized advertising cookies, where a consent banner is presented). You may withdraw consent at any time via your browser or the consent settings.
5. Your Rights
Depending on your jurisdiction (GDPR, CCPA and similar laws), you may have rights to access, correct, delete or restrict processing of personal data, and to object to processing or request portability. Because we hold essentially no personal data about you β we cannot even identify which files you processed, since we never see them β most requests are satisfied by clearing your own browser data. For anything else, contact info@onnax.com.
6. Children's Privacy
The Site is a general-audience utility service and does not knowingly collect personal information from children under 13 (or the applicable age in your jurisdiction).
7. Data Security
The strongest security measure we take is architectural: your files are never transmitted to us, so they cannot be breached from our side. The Site is served over HTTPS, and third-party libraries are loaded from reputable CDNs.
8. Changes to This Policy
We may update this policy as the Site evolves. Material changes will be reflected by the "Last updated" date at the top of this page.
