Stack Tower Privacy Policy

1. About this policy

This Privacy Policy explains how MasterFabric Information Technology Inc. ("we", "us") handles information when you use Stack Tower (the "App"). By using the App you agree to the practices described here. If you do not agree, please do not use the App.

2. Information we collect

Stack Tower keeps your game data on your device and does not send it to our servers. The App handles:

• Content — Game progress: high score, coins, upgrades, missions, daily reward status and settings (stored on your device)
• Device & usage — Language and sound/vibration preferences (stored on your device)
• Device & usage — When the Firebase configuration is enabled: an app-instance identifier, device model, OS version and IP address, used to deliver game settings

3. How we use information

We use information only to:

• Provide and maintain the features of the App
• Fix bugs, keep the App secure and improve performance
• Respond to your support requests
• Comply with legal obligations

4. Third-party services

The App uses the following providers. They process data under their own privacy policies:

• Firebase (Google) — Delivers remote game-balance settings (Remote Config); the app also works fully offline. Privacy policy: https://policies.google.com/privacy

5. Sharing and disclosure

We do not sell your personal information and do not use it for third-party advertising. We share information only with the service providers listed above, when required by law or to protect rights and safety, or in a merger or sale of our business (you would be notified).

6. Data retention

Game progress lives only on your device and is removed when you delete the app. Firebase technical identifiers are kept by Google according to its policy.

7. Your choices and rights

Depending on where you live (including under KVKK, GDPR and CCPA) you may request access, correction, deletion or portability of your data, or withdraw consent. Delete the app to remove all local data. For any server-side identifier, e-mail privacy@masterfabric.co and we will help.

You can also write to privacy@masterfabric.co. We reply within 30 days.

8. Security

Your game data is kept in the app's protected storage on your device, secured by the operating system. Connections to our service providers use encryption in transit (TLS). We cannot guarantee absolute security, since no method of storage or transmission is completely secure.

9. Children's privacy

Stack Tower is not directed to children under 13. We do not knowingly collect their data. If you believe a child has provided us information, contact privacy@masterfabric.co and we will delete it.

10. No tracking, no ads

Stack Tower does not track you across other apps or websites, does not use advertising identifiers and shows no third-party ads. It declares no tracking in its Apple privacy manifest.

11. Changes to this policy

We may update this policy. The "Last updated" date above shows the latest version, and material changes will be announced in the App or on this page.
