Privacy Policy

Effective date: December 30, 2024

Welcome to Sacred Geometry Visualizer ("we," "us," "the app"), developed by Qualhalla. We're committed to transparency about data practices in our Android app.


1) What data we collect

We do not maintain user accounts or collect personal information on our own servers. The app uses third-party SDKs that may collect certain data automatically for ads and analytics:

Advertising (Google AdMob)

Analytics (Firebase / Google Analytics for Firebase)

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.

Data handled by these SDKs is encrypted in transit and processed under Google's policies. We do not combine this 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:

This local data is not transmitted to us or any third party.

4) How collected data is used

We do not sell your personal data.

5) Your choices

6) Data sharing

We share data with Google (AdMob, Firebase, Play Billing) and their advertising/analytics partners to provide ads, measurement, and analytics. We do not share data with other third parties for marketing purposes.

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. Data collected by Google and its partners is retained and processed according to their policies and may be processed on servers outside your country.

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 region, you may have rights to access, delete, or limit processing of your data. Because we don't maintain accounts or store personal data ourselves, requests related to ad/analytics data are generally handled via device controls and Google's mechanisms. You can also contact us and we'll assist where 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."
