1. Who we are
Stacktail is an iOS arcade game published by E&D (an independent developer, "we"). This policy explains what data is processed when you use the app, why, and what your rights are.
For any question, contact us at verstand.france@gmail.com.
2. Data we process
Stacktail asks for no account, no name and no email address. Your progress (best score, coins, skins, settings) is stored on your device only and is not sent to our servers.
To fund the app through advertising and keep it stable, some technical data may be processed by our providers:
| Category | Examples | Purpose |
|---|---|---|
| Identifiers | Advertising identifier (IDFA), device identifier | Serving and measuring ads |
| Advertising data | Ads viewed, clicks, attribution events | Ad delivery and fraud prevention |
| Product interaction | Runs started, screens opened | Analytics and improvement |
| Diagnostics (crashes) | Crash reports, error logs | Stability and bug fixing |
| Performance | Load times, frame rate | Performance optimization |
We do not collect your name, precise location, contacts, photos, or health or financial data.
3. Ad tracking and consent (ATT)
In line with Apple's App Tracking Transparency rules, the app asks for your permission before any tracking for advertising purposes. If you decline, you can keep playing normally: ads are still shown but are not personalized using your advertising identifier. You can change this choice anytime in Settings > Privacy & Security > Tracking.
4. Partners and recipients
- AppLovin (MAX) — advertising network and mediation. See AppLovin's policy.
- Apple — App Store, in-app purchases (StoreKit), Game Center and system services. See Apple's policy.
In-app purchase payments are handled by Apple; we never receive or store your payment information.
5. Legal basis and retention
Where the GDPR applies, advertising processing relies on your consent, and diagnostics on our legitimate interest in keeping the service stable. Technical data is kept only as long as needed for the purposes described, then deleted or anonymized.
6. Your rights
- Access, rectification, erasure and restriction (GDPR).
- Withdraw tracking consent anytime via iOS settings.
- California residents (CCPA): the right not to have data "sold/shared".
- Uninstalling the app erases all progress stored on the device.
To exercise these rights: verstand.france@gmail.com.
7. Children
Stacktail is not specifically directed at children under 13 and does not knowingly collect their data.
