Privacy Policy

1. Who we are

Pitch Changer & Key Changer ("the app") is developed and published on Google Play by VELOX APP LTD ("we", "us"), a company registered in England and Wales under company number 17186614, with its registered office at 128 City Road, London, EC1V 2NX, United Kingdom. We are the controller of the analytics data described in section 4.

This policy covers the Pitch Changer & Key Changer Android app only. Our company privacy policy covers this website and emails you send us. For any privacy question, or to use your rights, email [email protected].

2. Summary

• There is no account or sign-in.
• The app shows no ads of any kind and does not use your advertising ID.
• The app has no media-library or broad storage permission. It can only reach the audio files you choose.
• Your songs and audio files are processed on your phone and are never uploaded. File names, song titles and file contents are never sent to us.
• The app uses Google Firebase (Analytics and Crashlytics) for usage statistics and crash reports.
• The optional one-time Pro purchase is handled by Google Play.
• We do not sell your data and do not share it with third parties for their own use.

3. What the app does on your device

• You choose which audio file to open through Android's system file picker, or by sending a file to the app from another app. The app can only reach files you select.
• Changing pitch, key and speed, and exporting, run on your phone. The app reads the file you selected and, if you export, writes the new audio file where you choose to save it or to the share sheet.
• While a song plays the app shows a media notification with playback controls and keeps playing with the screen off. The app may ask your permission to show this notification.
• The app keeps a short list of recently opened files and your pitch, speed and loop settings on your phone only. Uninstalling the app deletes everything it stored.

4. Analytics, crash reports and settings (Google Firebase)

The app uses Google Firebase Analytics and Firebase Crashlytics. Google provides them to us as a service provider (processor): it processes this data on our behalf and on our instructions. We collect:

• App interactions, for example that a song was opened (length range and format only), that pitch or speed was changed, whether an export finished or failed, which feature opened the Pro screen, and purchase steps.
• Crash logs and diagnostics: stack traces, device model, Android version, app version and performance information.
• A random app-instance identifier generated by Firebase. Your advertising ID is not used.
• Purchase events: that a Pro purchase happened.

We never send file names, song titles or file contents. We do not sell this data and do not share it with anyone else. Analytics data is kept for 2 months.

5. No ads

The app has no advertisements, no ad networks and no ad measurement. The advertising-ID permission is removed from the app, and ad personalisation, ad user data and ad storage are switched off.

6. Purchases (Google Play Billing)

Pro (saving the changed song, fine-tuning in cents and presets) is a one-time purchase, not a subscription, and is processed entirely by Google Play. We never see your payment details. The app asks Google Play whether Pro was purchased and keeps that yes-or-no answer on your device.

7. Contacting us

If you email us, we keep your message and address only to answer you, and delete them on request.

8. Children

The app is not directed at children. Its target audience is adults aged 18 and over, and we do not knowingly collect data from children.

9. Retention and deleting your data

• On your device: data inside the app stays there until you delete it or uninstall the app. It exists nowhere else. The audio files you export are saved where you chose and are yours to keep or delete.
• Analytics and crash data: deleted automatically after 2 months. There are no accounts, so we cannot look up data about you; email us with any request.
• Purchase records: Google keeps them under its own policies; we keep order information only as long as needed for accounts and tax.

10. International transfers

Google processes Firebase data in the United States and other countries. It uses safeguards recognised by UK and EU law for such transfers, such as standard contractual clauses.

11. Your rights

Under the UK GDPR (and the EU GDPR where it applies) you may have the right to access, correct, delete or restrict the use of your personal data, to object to it and to data portability. Email [email protected] to use them. If you are unhappy with how we handle your data, you can complain to the Information Commissioner's Office (ico.org.uk) or your local data protection authority.

12. Changes to this policy

If the app's data handling changes, we will update this page and its effective date before the new version is released.
