Kalulu Privacy Policy

Last updated: June 2026

Kalulu is an offline speech-to-text application developed by Chipenda Kalulu. This privacy policy explains how the app handles your data. The short version: Kalulu does not collect, store, or transmit any personal data.

1. Data Collection

Kalulu does not collect any personal information. The app does not require you to create an account, sign in, or provide any personal details to use its features.

2. Audio and Transcripts

All audio recordings and transcripts are processed entirely on your device. Your voice recordings are never uploaded to any server, never shared with third parties, and never leave your phone. Once you delete a recording or transcript within the app, it is permanently removed from your device.

3. Document Scanner

Images captured using the document scanner are processed locally on your device using on-device OCR technology. No images are uploaded or transmitted anywhere.

4. Internet Connection

Kalulu works fully offline. The app does not require an internet connection for any of its core features — transcription, document scanning, or saving transcripts. An internet connection is only used when processing a subscription payment through Google Play.

5. Permissions

Kalulu requests the following permissions:

• Microphone — required to record audio for transcription.
• Camera — required for the document scanner feature.
• Notifications — used only to show a recording indicator while the app is recording in the background.
• Storage — used to save recordings and transcripts to your device.

None of these permissions are used to collect or transmit data externally.

6. Google Play Billing

Kalulu uses Google Play's billing system to process subscription payments. Payment information is handled entirely by Google and is subject to Google's own privacy policy. Kalulu does not have access to your payment details.

7. Crash Reporting

Kalulu does not use any third-party analytics or crash reporting tools. No usage data is collected.

8. Children's Privacy

Kalulu is intended for users aged 18 and above. The app does not knowingly collect any information from children.

9. Changes to This Policy

If this privacy policy is updated, the new version will be published at this URL. Continued use of the app after any changes constitutes acceptance of the updated policy.
