DoubleTake

1. Introduction

DoubleTake (“the App”) is a photography and video app focused on dual-camera recording. It lets you switch between dual record, picture-in-picture (PiP), and split-screen layouts in one flow, and also includes a live filter camera, photo filter editing from your library, beauty retouching, and an in-app recording library (depending on the version installed on your device).

This Privacy Policy explains what information the App accesses, how it is used, and what stays on your device. We designed DoubleTake so that your photos, videos, and face data are not uploaded to our servers. Processing happens locally on your iPhone or iPad unless you explicitly use a system service such as the App Store for purchases.

By using the App, you agree to this Privacy Policy. If you do not agree, please uninstall the App.

2. Information We Do Not Collect

DoubleTake is a local-first tool. We do not operate user accounts and we do not collect personal information on our own servers, including:

2.1 Face Data (App Store Requirement)

This section addresses Apple App Store Review Guideline 2.1 requirements for apps that process face data.

What face data does the App collect?

The App does not collect or store face data. For live preview, beauty retouch, and related features, DoubleTake uses Apple’s on-device frameworks (including Vision and Core Image) to temporarily detect face rectangles or facial landmarks in memory. These calculations exist only for the current frame or the photo being edited and are discarded afterward. They are not written to disk as face profiles, not uploaded, and not shared with third parties.

How is face-related data used?

• Face bounding boxes: used for real-time camera preview, optional beauty effects, and smart framing hints on the current frame only;
• Facial regions: used to apply effects such as skin smoothing, spot removal, slim-face, dark-circle reduction, and tone evening within the current image or preview frame;
• No persistent face archive: the App does not build a face gallery, face ID, or biometric template.

Is face data shared or stored?

No. Face-related processing happens entirely on your device. It is not sent to our servers, not stored in an App database, and not written to persistent files as face data.

How long is face data retained?

It is not retained. Temporary face geometry exists only in memory during a single preview frame or single edit operation and is released immediately afterward.

3. Information Stored on Your Device

Although we do not collect data on our servers, the App stores some information locally on your device to function:

• App preferences (language, appearance/theme, sound, onboarding completion, and similar settings) using iOS local storage;
• In-app recording library — dual-camera and comprehensive recordings you save inside the App are stored in the App’s documents directory on your device;
• Local edit history — recent filter or camera history may be cached locally for convenience;
• Pro purchase status — whether you unlocked Pro is determined through Apple StoreKit; we do not receive your payment card details.

You can remove App-local data by deleting items inside the App or by uninstalling the App. Content saved to the system Photos library remains there until you delete it in Photos.

4. Permissions

The App requests only the permissions needed for its features. All granted access is used on-device:

• Camera — dual-camera recording, PiP, split-screen layouts, live filter capture, and photo/video recording. Preview and capture stay on your device;
• Photo Library (read) — select existing photos to apply filters and edits;
• Photo Library (add) — save photos and videos you export to your library;
• Microphone — record audio when you capture video with sound. Audio is stored locally with your video.

You can revoke permissions at any time in iOS Settings. Some features will not work without the relevant permission.

5. In-App Purchases (Pro)

DoubleTake offers an optional one-time Pro upgrade processed by Apple App Store and StoreKit. Apple handles payment, receipt validation, and restore purchases. We do not receive or store your full payment credentials. Purchase-related information is governed by Apple’s Privacy Policy.

6. Third-Party Services

The App does not integrate advertising SDKs, analytics SDKs, social login, or third-party tracking for developer marketing.

• Apple system services — App Store purchases, StoreKit transaction verification, and optional App Store review prompts;
• Links you open — the App may open this Privacy Policy, Terms of Use, or App Store pages in Safari or an in-app browser. Those pages are subject to their own policies;
• No developer upload server — apart from standard Apple purchase communication and pages you choose to open, the App does not upload your photos, videos, or face data to developer-operated servers.

7. Data Security

Because your media and face processing remain on your device, security depends primarily on your device protections (passcode, Face ID, Touch ID, and iOS system security). We recommend keeping your device updated and using a strong screen lock.

8. Children’s Privacy

The App is not directed at children under 13 (or the minimum age required in your region). We do not knowingly collect personal information from children. If you believe a child has provided personal information to us, please contact us and we will respond promptly.

9. Your Rights

Depending on your region, you may have rights to access, correct, or delete personal information. Because DoubleTake does not maintain developer-side accounts or server copies of your media, most user-controlled data is already on your device and can be removed by deleting content in the App, clearing Photos items you saved, or uninstalling the App.

For purchase-related requests (refunds, restore purchases), please use Apple’s standard App Store support channels.

10. Changes to This Policy

1. We may update this Privacy Policy when features, laws, or App Store requirements change. The effective date at the top will be revised accordingly.
2. Continued use of the App after an update means you accept the revised policy. If you do not agree, please stop using the App and uninstall it.

2. We are not responsible for loss of data caused by device failure, loss, or unauthorized access to your unlocked device;
3. This policy applies only to DoubleTake. Third-party websites or services you access outside the App are governed by their own policies.
