Privacy Policy

Effective date: September 7, 2026

This policy applies to the Android version of Sacred Geometry Visualizer, developed by Qualhalla ("we," "us"). Qualhalla is the controller for the app-related processing described below. You can contact us at jon.eman184@gmail.com.

1) What data we collect

We do not maintain user accounts or operate our own data-collection server. The Android app uses third-party services that may process the following data:

Advertising (Unity LevelPlay, ironSource, Google AdMob, and Unity Ads)

Approximate location derived from network information (not precise GPS)
Identifiers, which may include the Android Advertising ID where available and permitted
App activity/usage (interactions with ads, engagement/performance signals)
Device information/diagnostics (to measure performance and prevent fraud)
Consent and privacy signals used to honor your choices

Unity LevelPlay is the app's advertising mediation platform. The LevelPlay/ironSource network, Google AdMob, and Unity Ads are configured as advertising sources through LevelPlay. The app does not create or send its own persistent LevelPlay user ID. Which source serves an ad depends on mediation and bidding availability. Depending on your choices and the capabilities of the selected source, you may receive personalized, non-personalized, or limited ads.

Analytics (Firebase / Google Analytics for Firebase)

Approximate location (city/region derived from IP at collection time; GA4 does not store raw IP)
Identifiers (a Firebase app-instance ID; Advertising ID collection is disabled for Analytics)
App interactions/usage (feature use, screens/events such as pattern selection and settings changes)

Analytics collection is disabled by default and is enabled only when the consent state returned by Google's consent platform permits it. The core visualizer works without Analytics.

Consent management (Google User Messaging Platform)

Google's User Messaging Platform (UMP) determines whether a privacy message is required, displays that message, and stores consent signals so Google, Unity LevelPlay, and participating ad partners can honor your choices.

In-App Purchases (Google Play Billing)

Purchases are processed entirely by Google Play. We do not receive or store payment details such as credit card numbers. We only receive confirmation of purchase status to unlock premium features.

We do not combine SDK data with other datasets to identify you.

2) Microphone access

This app requests microphone permission to visualize audio in real-time. Audio data is processed entirely on your device and is never recorded, stored, or transmitted to any server. The microphone is used solely to analyze audio frequencies for driving the visual animations.

When you use the video recording feature, audio may be included in the exported video file which is saved locally to your device. This recorded content stays on your device and is not uploaded anywhere by the app.

3) Local data storage

The app stores the following data locally on your device:

Settings and preferences (visualization options, color choices, sensitivity settings)
Purchase status (whether premium features are unlocked)
Recorded videos (saved to your device's storage when you use the recording feature)

These settings and media remain on your device. Consent choices are also stored locally, but consent signals may be read by the advertising and analytics services described above.

4) Purposes and legal bases

Advertising: to fund the free app, deliver and measure ads, and prevent fraud. Where consent is legally required for device storage, personal-data use, or personalized advertising, we rely on your consent.
Analytics: with permission, to understand feature use and improve the app. Where consent applies, the legal basis is consent.
Purchases: to provide and restore Premium features. This processing is necessary to perform the purchase you request.
Security and legal compliance: providers may process limited data to prevent fraud, secure their services, or comply with law under applicable legitimate-interest or legal-obligation grounds.

We do not sell your personal data.

5) Your choices

Consent choices: where required, the app presents Google's consent message before requesting ads. Refusing optional purposes does not block the core visualizer.
Change or withdraw consent: open Settings → Privacy → Manage Privacy Choices whenever that control is required for your region. New ad requests and Analytics collection are updated after you save a new choice.
Privacy policy: the Android Settings screen always includes a link back to this policy.
Advertising ID controls: You can reset your Android Advertising ID and opt out of ad personalization in your device settings (Settings → Google → Ads).
Microphone permission: You can revoke microphone access at any time in your device settings, though this will disable the audio-reactive visualization features.
Location: We don't request location permission; approximate location for ads/analytics may be inferred by partners from network signals.

6) Data sharing

Data may be shared with Unity (LevelPlay/ironSource and Unity Ads), Google (UMP, AdMob, Firebase, and Play Billing), and the additional ad partners identified in the consent message. The Android app includes LevelPlay integrations for the ironSource network, Google AdMob, and Unity Ads. The advertising source selected for a particular ad request, and that source's participating demand partners, may receive data as described in this policy and the consent message. We do not share data with unrelated third parties for our own direct marketing.

7) Cookies and local storage

Ad SDKs may use cookies or similar technologies to deliver and measure ads. App settings you change are stored locally on your device and are not sent to us.

8) Data retention & international transfers

We do not store personal data on our own servers. Unity, Google, and participating ad partners retain data according to their own policies and settings. They may process data outside your country and use legally recognized transfer safeguards where required. Use the links below or contact us for more information.

9) Children

This app is not directed to children under 13 and contains advertising. Parents/guardians should supervise use by minors.

10) Your rights

Depending on your location, you may have rights to access, correct, erase, restrict, or object to processing; receive portable data; and withdraw consent without affecting processing that was lawful before withdrawal. You may also lodge a complaint with your local data-protection authority. Because we have no accounts or first-party server database, we may need device or service information to help route a request to the relevant provider. Contact us and we will assist where reasonably possible.

11) Third-party policies

12) Changes to this policy

We may update this policy. We will post the updated version here and change the "Effective date."
