We collect certain personal information through advertising tracking technologies, including:

• Advertising Identifiers (e.g., GAID on Android) – alphanumeric strings provided by your device's operating system, used for ad targeting and measurement.
• IP address and coarse location – we collect your IP address to infer your general location (country, state, or city) for ad delivery and to support regional advertising campaigns.
• Device information – model, OS version, language, and screen resolution.
• Interaction data – ad views, clicks, and installs attributed to our campaigns.

We do not collect sensitive data (e.g., health, racial/ethnic origin, or precise geolocation) for advertising purposes.

3 Purposes of Collecting Advertising-Related Data

We and our advertising partners use advertising-related data for the following purposes:

• Personalized advertising – showing ads that are more relevant to your interests based on your activity.
• Ad measurement & analytics – tracking impressions, clicks, and installs to measure campaign effectiveness.
• Frequency capping – limiting the number of times you see the same ad.
• Fraud prevention – detecting and preventing invalid traffic or fraudulent activity.
• Re-engagement – informing existing users about updates or new content.
• Geographic targeting – using coarse location (derived from IP address) to deliver regionally relevant ads and content.

All processing is based on your consent (where required) or our legitimate interest in delivering and improving our Services.

4 Disclosure of Advertising-Related Information
