| Service | Purpose | Privacy Policy |

| Google Fonts | Loads Inter & Bebas Neue typefaces | policies.google.com/privacy |

6. Children's Privacy
TrueTime.zone is not directed at children under 13 years of age. We do not knowingly collect information from children. If you believe a child has provided information through third-party services listed above, please contact those services directly.
7. Data Security
Since we do not collect or transmit personal data, there is no personal data stored on our servers that could be breached. All user preferences remain in your browser's localStorage under your full control.
8. Your Rights (GDPR / LGPD / CCPA)
Because we do not process personal data ourselves, most data subject rights (access, rectification, erasure, portability) apply primarily to the third-party services listed in Section 5. For data held in your browser localStorage, you can exercise full control by clearing your browser data at any time.
For advertising-related data managed by Google, you can exercise your rights via Google's Data & Privacy dashboard.
9. Changes to This Policy
We may update this Privacy Policy from time to time. We will update the "Last updated" date at the top of this page. Continued use of TrueTime.zone after any changes constitutes your acceptance of the updated policy.
