Your privacy is very important to us. This Privacy Policy explains what information we collect when you use our applications, how we use it, and how we protect it.

1. Information We Collect Automatically

Our applications do not collect personal information directly or store data on our own servers. However, we use third-party services that may automatically collect technical and behavioral data for analytics, performance improvement, and advertising.

Some applications (such as MindCards) may allow users to upload documents. These documents may contain personal data depending on the content provided by the user.

These services include:

• Firebase Analytics: collects anonymous usage data.

• Google AdMob: serves contextual or personalized ads.
• Chartboost: displays ads and collects related metrics.
• Inmobi: mobile advertising platform.
• Liftoff: mobile app marketing and retargeting platform.
