4K Wallpaper

We automatically collect limited data to improve the app and show relevant ads, using Firebase (analytics) and AdMob (advertising).

• Device info: model, OS version, unique advertising ID (Android Advertising ID / IDFA).
• Usage data: popular wallpapers, crash logs, app interactions (Firebase).
• Ad interaction: impressions, clicks – via AdMob.
• IP address (anonymized for analytics).

No personal identifiers (name, email, location) are collected directly by us.

We do not sell your data. We share only with trusted partners to run the app:

• Firebase (Google): analytics, crash reports. Firebase privacy
• AdMob (Google): serve ads. AdMob policy

Data helps us fix crashes, understand preferences, and keep the app free (ads).

If you are in the European Economic Area or UK, you have the following rights:

• Access: request what data we hold.
• Erasure (right to be forgotten).
• Object to processing: including personalized ads.

Legal basis: we rely on your consent for analytics and ads. You can withdraw consent anytime by resetting your advertising ID (see section 8).

California residents have specific rights:

• Right to know categories of personal information collected.
• Right to delete personal information.
• Right to opt-out of “sale” (we don’t sell, but sharing for cross-context advertising may be considered sale).

Opt-out of targeted ads: enable “Limit Ad Tracking” (iOS) or “Opt out of Ads Personalization” (Android). We do not discriminate for exercising your rights.

Our app is not directed to children under 13. We do not knowingly collect personal information from children under 13. If we discover such data, we delete it immediately. Ad networks are restricted from interest-based advertising for child users.

We use Google AdMob. Ads may be personalized based on your advertising ID. To opt out:

• Android: Settings → Google → Ads → Enable “Opt out of Ads Personalization”.
• iOS: Settings → Privacy → Tracking → disable “Allow Apps to Request to Track”.

If you opt out, you’ll still see ads — but they won’t be based on your interests.

Firebase helps us understand aggregate usage. It collects anonymized IP, device IDs, and in-app events. Data is retained as long as needed for analytics. You can learn more at Firebase Privacy.

We use commercially reasonable security measures. No method is 100% secure. Data collected via Firebase/AdMob is kept per their retention policies (generally up to 14 months for analytics).

If we update this policy, we'll post the new version here and update the "Last Updated" date. Continuing to use the app means you accept the revised policy.
