Privacy Policy

Last updated: July 30, 2026

VividMap builds ChronosMap and yunji. Both apps are designed to work with data on your device and the photos or files you choose. We do not create user accounts and do not collect, sell, or share personal data.

What we do not collect

• We do not collect your name, email, contacts, or precise location history.
• We do not use third-party advertising or analytics SDKs.
• We do not track in-app behavior to build advertising profiles.

Your photos and files

yunji reads capture time and location metadata only from the photos you choose to import, and saves copies on your device. ChronosMap opens, saves, and imports only the map files you explicitly choose. In both apps your content stays on your device, or in your own private iCloud if you turn sync on.

Map services

Both apps use Apple MapKit to draw maps. Map tiles and base services are provided by Apple and are subject to Apple's privacy policy.

Sharing

You can export and share ChronosMap files, and your yunji data syncs only through your personal iCloud. Anything you choose to share is your choice — review it before you send it.
