Privacy Policy

Last updated: April 28, 2026

Voice Isolation — Clean Audio ("the App") is published by Bulpara Inc ("we", "us", "our"). The short version: we don't collect, transmit, or store any of your audio, video, or personal data on a server. Everything happens on your iPhone.

1. What we do not collect

We do not run any backend servers that receive your data. The App processes every clip locally on your device using Apple's AVAudioEngine and bundled Core ML models.

2. What stays on your device

The following information is stored only on your iPhone, in the App's sandboxed storage:

If you delete the App, this data is removed by iOS.

3. Subscriptions and payments

In-app purchases (Voice Isolation Pro monthly and annual subscriptions) are handled entirely by Apple's StoreKit framework. We never see your payment details, Apple ID, or billing address. Apple sends us only an anonymous indication that an active subscription exists for your device.

You can manage or cancel your subscription at any time via Settings → Apple ID → Subscriptions.

4. Advertising (free tier only)

When you're on the free tier, the App displays banner ads on the Home and History tabs and an occasional interstitial ad after exporting a clip. Ads are served by Google AdMob.

To deliver and measure ads, AdMob may collect:

You can decline tracking permission when prompted, in which case AdMob will serve non-personalized ads. Google's privacy policy is available at policies.google.com/privacy.

Pro subscribers see no ads and no advertising data is collected from Pro accounts.

5. Permissions the App requests

6. Children

The App is rated 4+ and does not knowingly collect personal information from children. Since we don't collect personal data from anyone, no special provisions are required under COPPA or similar laws.

7. Data retention and deletion

Because we do not collect any data on our servers, there is nothing for us to retain or delete. Data stored on your device can be removed at any time by deleting clips within the App or by deleting the App from your iPhone. You do not need to make a "data deletion request" — there is no server-side data to delete.

8. Changes to this policy

We may update this policy from time to time. Material changes will be announced in-app and on this page. The "Last updated" date at the top reflects the most recent revision.
