My Demonlist is a personal companion app for players of Geometry Dash. This Privacy Policy explains how information is handled when using the app.

Information Collection

My Demonlist itself does not require accounts, logins, or personal identifiers, and does not collect or store any personal information you provide.

However, the app displays advertisements through Google AdMob, which may collect certain device-level information — including your device's advertising identifier, approximate (coarse) location, and data about ad interactions and app performance — in order to serve and measure ads. See the "Advertising" section below for details.

Local Data Storage

All data you enter into My Demonlist — including demon names, rankings, attempts, and run progress — is stored locally on your device only, and is not uploaded to any external servers by us.

Advertising

The free version of the app displays advertisements provided by Google AdMob and its advertising partners. To support advertising, AdMob may collect:

• Your device's advertising identifier (used to personalize ads, if you allow tracking)
• Approximate location (based on IP address)
• Information about ads you've seen and interacted with
• App performance data (such as launch time and crash diagnostics)

On iOS, you will be asked for permission via Apple's App Tracking Transparency system before any tracking-related data is used. You can decline this at any time; the app will still display ads, just without personalization.

If you are located in the EEA, UK, or another region requiring consent, you will be shown a consent form before ads are loaded, in accordance with applicable privacy regulations.

For more information on how Google handles this data, see Google's Privacy Policy: https://policies.google.com/privacy

Purchases

My Demonlist offers an optional one-time in-app purchase to remove advertisements. Purchases are processed securely through Apple's App Store and are subject to Apple's payment and privacy policies. My Demonlist does not have access to your payment information.

Third-Party Services

Any third-party services used by the app (such as Google AdMob or Apple's in-app purchase system) operate under their own privacy policies, linked above where applicable.
