Last updated: May 10, 2026

Deep Cave ("the App") is a mobile game developed by Nemiaco (Youssef T.). This Privacy Policy explains what data we collect, why, and how it is used.

1. Data We Collect

1.1 Gameplay data

When you play Deep Cave, the App assigns you an anonymous identifier that is not linked to your name, email address, or any other personal identity. The following data is stored on our servers and associated with that identifier:

Your chosen nickname (optional — a default one is generated if you skip this step)
Your best score (maximum depth reached)
Your daily challenge scores
Groups you have joined and your nickname within those groups

1.2 Advertising

The App displays ads served by Google. To serve and measure ads, Google may collect:

Advertising identifier (only if you grant permission via the App Tracking Transparency prompt on iOS, or have not opted out on Android)
Approximate location at country/region level
Device information (model, OS version, screen size)
Ad interaction data (impressions, clicks) and diagnostic data

On devices in the EU/EEA, a consent form is shown before any personalised ads are served. Google's data practices are governed by Google's Privacy Policy.

2. How We Use Your Data

Google — for cloud infrastructure (leaderboards, authentication) and advertising. See Google's Privacy Policy.

Google acts as a data processor under appropriate data processing agreements.

4. Data Retention

Leaderboard scores and nicknames: retained while the App is live. You can request deletion by contacting us (see §6).
Your anonymous identifier persists on-device until the App is uninstalled or app data is cleared.
Ad-related data: managed by Google per their own retention policies.

5. Your Rights (GDPR / CCPA)

Depending on your country, you may have the right to:

Access the data we hold about you

Deep Cave is not directed at children under 13 (or 16 in the EU). We do not knowingly collect personal data from children. If you believe a child has provided us with data, please contact us and we will delete it promptly.

8. Changes to This Policy

We may update this policy from time to time. The "Last updated" date at the top will be revised accordingly. Continued use of the App after changes constitutes acceptance of the updated policy.
