VaultVoice AI

A private, fully on-device voice recorder & transcriber

Privacy Policy

Effective date: July 14, 2026 · Applies to the VaultVoice AI Android app (package name: com.voicejoker.app)

This Privacy Policy describes how VaultVoice AI ("we", "our", or "the app") handles your information. VaultVoice AI is designed to be private by design: recording, transcription, and summarization all happen entirely on your device. The app requires no account, declares no internet permission, and does not collect, transmit, sell, or share any personal data.

1. Data We Collect

We do not collect any data. VaultVoice AI has no servers, no user accounts, no analytics, no advertising SDKs, and no third-party tracking of any kind. The app does not request the Android INTERNET permission, so it is technically unable to send anything off your device.

2. Data Stored on Your Device

Everything you create in VaultVoice AI is stored only in the app's private storage on your own device. This includes:

This data never leaves your device unless you explicitly choose to share or export it (see Section 5). We have no access to it.

3. On-Device Processing

Speech-to-text transcription and summarization are performed locally on your device using bundled machine-learning models. Your voice audio and the resulting text are processed in the app's own sandbox and are never uploaded to any server — ours or anyone else's.

4. Permissions the App Uses

VaultVoice AI explicitly removes the INTERNET and ACCESS_NETWORK_STATE permissions, including any that third-party libraries might try to add.

5. Sharing and Export

VaultVoice AI lets you export transcripts as TXT, Markdown, or SRT files and share them through the Android share sheet. Sharing happens only when you initiate it, and the destination (for example a messaging or email app you choose) is entirely under your control. Once shared, the data is governed by the receiving app's own privacy policy.

6. Data Retention and Deletion

Your recordings, transcripts, and summaries remain on your device until you delete them. You can delete individual recordings inside the app, and deleting a recording also removes its transcript and summaries. Uninstalling the app permanently removes all of its data from your device. The app also opts out of Android's cloud backup (allowBackup=false), so your data is not copied to any backup service. Because we never receive your data, there is nothing for us to retain or delete on any server.

7. Children's Privacy

VaultVoice AI does not collect personal information from anyone, including children. The app contains no ads and no social features.

8. Security

Your data is stored in the app's private, sandboxed storage provided by Android, which is inaccessible to other apps under normal system protections. Because the app has no network capability, there is no network exposure.

9. Changes to This Policy

If a future version of VaultVoice AI changes how it handles data — for example by adding optional subscriptions or advertising — we will update this policy and revise the effective date above before that version is released. Material changes will be highlighted in the app's update notes.
