1. Introduction
Dual Camera Front Back (the “App”) is a dual-camera recording tool that lets you capture the front and rear cameras together in layouts such as dual record, picture-in-picture, and split screen. It also offers photo/video capture, live filters, album editing, beauty tools, a local portfolio, teleprompter, brand kit, and caption drafts (features available depend on the version installed on your device).
This Privacy Policy explains that the App does not collect, store, upload, or share your personal information or user content with us. Processing happens on your device. By using the App, you acknowledge and accept this Policy.
2. Information Collection and Use
The App is a local-only utility. Features run on your device. We do not collect user data, including but not limited to:
We do not collect:
- Personal identity information: name, phone number, email, avatar, nickname, and similar identifiers;
- Device information: device model, OS version, device ID, IP address, precise location, or network status for analytics;
- Usage analytics: session length, tap logs, feature usage telemetry, or behavioral tracking;
- Capture and edit content: photos, Live Photos, videos, dual-camera compositions, and filter/beauty edits are previewed or saved only on your device (for example, to your Photos library or the App’s local portfolio). We do not collect or upload them;
- Face and image data: face detection, beauty, and related effects are processed in real time on device. No face images or face features are stored or uploaded;
- Speech / captions (when used): optional caption drafts use on-device speech recognition when available. Audio and transcripts stay on your device and are not sent to our servers;
- Local preferences: language, theme, framing, and similar settings are stored only on your device and are removed when you uninstall the App.
2A. Face Data
This section describes how the App handles face-related data to meet App Store Guideline 2.1 expectations for face data.
1. What face data does the App collect?
The App does not collect or store face data. For features that need face awareness, we temporarily compute face location (for example, a bounding box) or a face region in device memory using Apple system frameworks (such as Vision). Results are used only for that frame or that edit, then discarded. They are not written to disk, not uploaded, and not shared with any third party.
2. How is face-related data used?
- Face bounding box: used for live camera preview, beauty / portrait-related retouching, optional face-region guidance, and (where available) smart switching based on on-screen face activity. Computed in real time on the current frame or photo. Results are not saved as a face profile.
- Face-region processing: beauty effects such as skin smoothing or face reshaping apply image processing only within the current photo or preview frame. Output is shown to you or saved by you to Photos. We do not keep face images or biometric templates.
3. Is face data shared with third parties? Where is it stored?
No. Face data is not shared with any third party. All face-related computation stays in on-device memory. It is not stored on a server, not stored in an App database, and not persisted to files.
4. Retention
None. Face location and related temporary values exist only during a single live process or single-image edit, then are released. There is no retention period.
5. Where this is covered in this Policy
- Section 2 “Information Collection and Use”, item on face and image data;
- This Section 2A “Face Data” in full.
Short excerpt for App Review:
“The App does not collect or store face data. For live filters, beauty, face-region processing, and related on-device features, Apple frameworks (such as Vision) temporarily compute face location or face regions in device memory for the current frame or photo only. Results are discarded after processing, are not written to disk, are not uploaded, and are not shared with any third party. There is no retention period.”
3. Permissions
The App requests only permissions needed for core features. Data stays on your device:
- Camera: dual-camera capture and preview (dual record, picture-in-picture, split screen), photos, and video. Frames are shown and processed on your device only;
- Photos / library access: choose images for filters and edits, and save photos/videos to the system Photos library or the App’s local portfolio;
- Microphone (when applicable): record audio with video. Audio/video remain local;
- Speech recognition (when applicable): optional caption drafts. Prefer on-device recognition when supported; content is not uploaded to our servers.
4. Data Storage and Security
1. Storage
The App does not store user content on our servers. Preferences, recordings, and edits remain under your control on your device (and, if you choose, in Photos).
2. Security
Because we do not collect or upload your content, there is no developer-side risk of leak, sale, or misuse of that data. Protect local device access with your device passcode, Face ID, Touch ID, or equivalent.
5. Sharing and Disclosure
Because the App does not collect personal data for us, we do not share, disclose, transfer, or sell your personal information or usage data to any third party (including the developer), and we do not partner with third parties to collect or analyze your data inside the App.
6. Third-Party Services
The App does not include ads, analytics SDKs, third-party login, or social tracking. Media processing is on-device by default.
1. Apple system services
Optional Pro unlock is a one-time non-consumable In-App Purchase via Apple App Store and StoreKit. We do not collect or store your full payment card details or complete billing statements. Apple processes transactions under Apple’s privacy policy.
2. Other
- No advertising; no third-party behavioral tracking
- No third-party account system operated by us
- Except when you open this Privacy Policy page in a browser, or when the system needs network access for In-App Purchase / Restore Purchases, the App does not upload your photos or face data to developer servers
7. Your Rights
Because we do not collect personal data about you, there is typically no account data for us to access, correct, or delete. To clear local App data on your device, uninstall the App.
8. Changes to This Policy
- We may update this Policy when features or legal requirements change. Updated versions will be posted here or otherwise reasonably brought to your attention.
- Continued use after an update means you accept the revised Policy. If you do not agree, stop using the App and uninstall it.
