Privacy Policy

Last updated: June 2026

1. Information we collect

Delta Hub works with no accounts or sign-in and collects the minimum information needed:

  • We don't create accounts or ask for your email, name or other personal data.
  • A notifications token (FCM) generated by the device, so we can send you alerts if you enable them.
  • An advertising identifier managed by Google AdMob to show ads.
  • Anonymized usage and crash metrics (Firebase), with no personal identification.
  • Your preferences, saved articles and the Delta tab history are stored ONLY on your device.

2. How we use the information

We use this information solely to:

  • Show you the content (news, guides, videos) in your language.
  • Send you news notifications if you've enabled them.
  • Show ads that keep the app free.
  • Detect errors and improve stability and performance.

3. Advertising

Delta Hub shows ads through Google AdMob (banner, interstitial, rewarded and app open). In the European Union we show the UMP/GDPR consent before loading ads, and non-personalized ads are used for audiences that require it. You can reset or limit the advertising identifier from your device settings.

4. Data sharing

We don't sell your data. Only these providers are involved, each with its own privacy policy:

  • Firebase (Firestore for content, Messaging for notifications, Analytics)
  • Google AdMob (advertising)

5. Storage on your device

Your saved articles, preferences (language, theme, notifications) and the Delta tab key history are stored locally on your phone. You can delete them from the app itself (Settings) or by uninstalling the app; they are not uploaded to any server.

6. Children and families

Delta Hub is about Roblox, a game with a young audience, and it is an informational and entertainment content app. It is not directed exclusively at children under 13, nor does it knowingly collect personal data from minors. Advertising is adjusted by audience in line with applicable policies.

7. Your rights

Since there are no accounts, we don't store personal data of yours on a server except the notifications token. You can request its deletion by writing to us, delete your local data from the app, and revoke permissions (notifications) from your device settings. More details on the "Delete data" page.
