Privacy Policy

This page explains how Yyago（https://yyago.top/en）collects, uses and protects your information. All computation on this tool site happens locally in your browser — we never upload your input.

1. Information we collect

• Usage data: anonymous visit statistics (page, device type, region) used to improve the service.
• Preferences: for example, theme (light/dark) is stored in your local browser.
• We donotcollect the plaintext you enter while using tools (such as text to encrypt or URLs).

2. Cookies

We use cookies to keep the site working, remember your preferences, and serve ads when you consent. You can manage or clear cookies in your browser settings.

3. Advertising (Google AdSense)

This site uses Google AdSense to display ads. Google and its partners may use cookies (including advertising cookies) to serve personalized or non-personalized ads based on your past visits:

• In the European Economic Area (EEA) and applicable regions, we obtain your consent through Google Funding Choices / TCF v2 consent management platform.
• In other regions, we obtain your choice through this site’s consent banner; you can accept personalized ads, keep only essential features, or reject ads.
• After refusing or withdrawing consent, we only show non-personalized ads (or no ads, per your choice), which does not affect core tool functionality.

You can visit Google Ads Settings or YourAdChoicesto manage your ad preferences.

4. Your rights (GDPR / CCPA)

• GDPR (EU): you have the right to access, correct and delete your personal data, and to withdraw ad consent at any time.
• CCPA (California): you have the right to opt out of the "sale" of your personal information and to know how we use your data.

5. Contact us

For any questions about privacy or advertising, please contact us via the feedback pageor email contact@yyago.top.

6. Third-party processors

To provide certain features, the following third-party services may handle a limited amount of your data. We only pass the minimum information the feature requires:

• Google AdSense: ad serving and measurement, which may use cookies and device identifiers;
• Feedback relay gateway: feedback you submit (including the optional contact field) is forwarded to our inbox through a third-party relay service;
• IP lookup API: when you use the IP lookup, the public IP you connect from is sent to a third-party lookup service solely to return geolocation data;
• Public CDNs: static assets are delivered by public CDNs, which keep standard access logs (IP, time, user agent).

7. Data retention

Anonymous statistics and access logs are retained by those providers under their own policies. Feedback you submit is kept for up to one year after the issue is resolved, then deleted. We do not build usage profiles tied to your identity.

8. Children's privacy

This site targets general users capable of making their own decisions. It is not directed at children under 13, and we do not knowingly collect their personal information. If you believe we have, contact us and we will delete it.

9. Changes to this policy

If this policy changes materially, we will update the "Last updated" date at the top of this page and the revision takes effect immediately. Continuing to use the site means you accept the updated policy; check back when advertising or privacy practices change.
