Privacy Policy

Last updated: May 30, 2026

1. Local Processing (Zero Data Collection)

Eurika is designed as a suite of client-side browser tools. This means that all data you input into our tools is processed locally on your device.

  • We do not upload your QR code data to any server.
  • We do not store your generated QR codes, WiFi passwords, emails, or TOTP keys.
  • We do not have a database of users, as we do not require user accounts.

2. Third-Party Services & Google AdSense

While the tools themselves do not collect your data, Eurika relies on advertising to remain free. We use Google AdSense to display ads on our site.

Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to our website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to our site and/or other sites on the Internet.

You may opt out of personalized advertising by visiting Google's Ads Settings. Alternatively, you can opt out of a third-party vendor's use of cookies for personalized advertising by visiting www.aboutads.info.

3. Analytics

We may use basic analytics (such as Google Analytics or similar services) to understand general traffic patterns, such as the number of visitors or the most popular tools. This data is aggregated and anonymized, and it does not contain any of the content you input into our tools.

4. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. Thus, we advise you to review this page periodically for any changes. We will notify you of any changes by posting the new Privacy Policy on this page. These changes are effective immediately, after they are posted on this page.

5. Children's Privacy

Eurika Tools does not knowingly collect or solicit any information from anyone under the age of 13 (or 16 in certain European jurisdictions). Our website and tools are directed at a general audience. If we learn that we have inadvertently collected personal information from a child without verified parental consent, we will delete that information as quickly as possible.

6. Your Regional Privacy Rights (CCPA, CPRA, GDPR)

Depending on your location, you may have specific rights regarding your personal data under local laws (such as the GDPR in Europe or the CCPA/CPRA in California). While Eurika Tools does not locally store your data, our advertising partners (Google) do utilize tracking cookies.

  • Consent Management: You can review, modify, or withdraw your consent for personalized advertising at any time using the "Privacy & Messaging" or "Manage Ad Preferences" link located in the footer of our website.
