Privacy Policy

👋 Introduction

DualBlur is a dual-camera recorder that runs entirely on your device. There is no DualBlur server, no account, no cloud component. This page describes — mostly — the things this app does not do.

🚫 Data we don't collect

• No analytics or telemetry of any kind
• No user accounts, emails, or identifiers
• No advertising IDs (IDFA), device fingerprints, or marketing profiles
• No crash reports sent off your device
• No usage statistics, no event tracking

💾 Data stored locally

The app keeps a few things on your device, and only on your device:

• App preferences (layout, blur settings, zoom levels, picture-in-picture position) via Apple's standard UserDefaults
• Photos and videos you capture, saved to your Photos library through Apple's PHPhotoLibrary API

None of this leaves your phone. Uninstalling the app removes the preferences; your captures stay in Photos because they belong to you.

🛰️ Network access

DualBlur makes no network calls. The app works fully offline and contains no networking code. There is nothing to send, and no one we'd send it to.

🧱 Third-party services

None. No SDKs, no analytics frameworks, no crash reporters, no advertising libraries. The app has zero external dependencies — it's pure native iOS, built only on Apple's frameworks.

🔑 Permissions

iOS will ask you to grant three permissions, all required for the app to function:

• Camera — "DualBlur records video from front and back cameras simultaneously."
• Microphone — "DualBlur records audio with your videos."
• Photo Library (add only) — "DualBlur saves photos and videos you capture."

These are the only permissions the app requests. The Photo Library permission is "add only" — the app can save your captures, but cannot read your existing photos.

🎞️ Content ownership

Anything you record belongs to you. Captures save to your Photos library and the app has no further access to them. DualBlur does not copy, scan, transmit, or analyse your content.

🙈 Face blur & face detection

DualBlur can blur or pixelate faces in your captures. To do this it uses Apple's on-device Vision framework to detect where faces appear in each camera frame.

• What is detected — rectangular coordinates (bounding boxes) marking the location of faces in the current frame. Nothing else.
• What is not done — no face recognition or identification. DualBlur does not create or store faceprints, face templates, facial geometry, or any biometric identifier. It cannot determine who a person is and does not infer age, gender, emotion, or any other attribute.
• Use — the detected rectangles position the blur/pixelation mask (and an optional cosmetic on-screen label) over the face area so faces are obscured. That is the only use.
• Processing location — entirely on your device. Face detection never contacts a server; the app contains no networking code.
• Retention — none. Face rectangles exist only momentarily in memory while a frame is processed, are continuously overwritten, and are discarded within a fraction of a second. They are never written to disk, never saved, and never leave the device.
• Sharing — never. No face data is shared with the developer or any third party, because none is collected, stored, or transmitted.

Only the finished photo or video — with faces already blurred — is saved, and only to your own Photos library.

👶 Children's privacy

The app does not knowingly collect data from anyone — children included — because it doesn't collect data at all. Given the camera and recording nature of the app, parental discretion is advised.

🛠️ Your rights and controls

• Revoke any permission any time via iOS Settings → DualBlur
• Uninstalling the app removes all of its preferences from your device
• Your captures remain yours, in your Photos library, under your control
