Privacy Policy for NyQuistRx

Effective date: June 11, 2026  •  Last updated: June 11, 2026

NyQuistRx ("we," "us," or "the app") respects your privacy. This Privacy Policy explains what information the app collects, how it is used, and the choices you have. By using NyQuistRx you agree to this policy.

If you have questions, contact us at deav1629@gmail.com.


1. Who we are

NyQuistRx is a mobile audio application that lets you import your own audio files and apply digital signal processing (slowed playback and reverb effects). Processing is performed on our servers and the result is returned to your device.

2. Information we collect

We have designed NyQuistRx to collect as little personal information as possible. We do not ask you to create an account, and we do not collect your name, email address, phone number, or contacts.

a) Anonymous device identifier

When you first open the app, we sign you in anonymously using Firebase Authentication. This creates a random, anonymous identifier that is not tied to your real-world identity. We use it only to apply fair-use processing limits (for example, daily processing caps) and to associate a subscription with your installation.

b) Audio you choose to process

When you process a track, the audio file (or a short clip of it) is uploaded to our processing server, the effect is applied, and the processed result is sent back to your device. Uploaded audio is used solely to perform the processing you requested and is automatically and permanently deleted from our servers immediately after processing completes. We do not keep, listen to, analyze, share, or sell your audio.

c) Usage and analytics data

We use Firebase Analytics to understand how the app is used in aggregate (for example, how often a feature is opened or a track is processed). This helps us improve the app. You can opt out of analytics at any time from the app's Privacy and Legal settings.

d) Advertising data

Free versions of the app display ads served by Google AdMob. AdMob may access your device's Advertising ID and use it to show more relevant ads and to measure ad performance, in accordance with Google's policies. You can reset or limit your Advertising ID in your device settings. Premium subscribers do not see ads.

e) Subscription and purchase data

If you subscribe to NyQuistRx Premium, the purchase is processed by Google Play Billing, and subscription status is managed through RevenueCat. We never receive or store your payment card details — those are handled entirely by Google. We receive only the status of your subscription (active, expired, cancelled).

f) Local settings

Your preferences (such as default speed, reverb, and Ambient Pause) and your imported track list are stored locally on your device and are not transmitted to us.

3. Device permissions

We do not access your audio library, files, location, camera, or microphone beyond what you explicitly select.

4. How we use information

We do not sell your personal information.

5. Third-party services

6. Data retention

7. Your choices and rights

8. Children's privacy

NyQuistRx is not directed to children under the age of 13 (or the equivalent minimum age in your jurisdiction), and we do not knowingly collect personal information from children. If you believe a child has provided us with information, contact us and we will address it.

9. Security

We use industry-standard measures to protect data in transit (encrypted HTTPS connections). No method of transmission or storage is 100% secure, but because we retain so little data, your exposure is minimal.

10. Changes to this policy

We may update this Privacy Policy from time to time. Material changes will be reflected by updating the "Last updated" date above. Continued use of the app after changes constitutes acceptance of the revised policy.
