Otehon Camera — Privacy Policy

Last updated: 2026-08-22
Application: Otehon Camera (お手本カメラ) for iOS

Introduction

Otehon Camera ("the App") is an iPhone camera app that assists you while you shoot: composition guides, scene-based automatic camera settings, and an optional finishing touch after capture.

The App collects no personal information, no photos, and no usage data. Everything it does happens on your iPhone.

1. Information We Collect

None.

The App does not collect, record, or transmit any of the following:

• Personally identifiable information such as your name, email address, phone number, or account details
• Your photos, the camera preview feed, or any analysis derived from them
• Location data
• Device identifiers or advertising identifiers (IDFA)
• Usage data, interaction logs, crash logs, or any other analytics

The App has no account system and never asks you to sign in.

2. Network Communication

The App has no network functionality whatsoever.

Its program contains no code for communicating over the internet. Consequently, no data of any kind — photos, analysis results, or settings — is ever sent to the developer or to any third party. Every feature works identically in Airplane Mode.

3. How Camera Images Are Handled (entirely on your device)

Composition guides, subject detection, level/tilt detection, exposure adjustment, and the post-capture finishing touch are all performed exclusively on your device, using Apple's built-in frameworks (AVFoundation, Vision, Core Motion, Core Image).

• The camera preview feed is used only to display the viewfinder and to compute the guides. It is never stored and never transmitted.
• Analysis results (subject position, tilt angle, and so on) are used to draw the guides in the moment and are not recorded.
• No cloud AI service or external image-analysis service is used.

4. Permissions the App Requests

The App requests only the following two permissions.

Camera access (NSCameraUsageDescription)

Used to capture photos and to display composition guides, level indication, and brightness advice in real time. All analysis of the camera feed happens solely on this device; neither the video feed nor your photos are sent to any external server.

Add to Photo Library (NSPhotoLibraryAddUsageDescription)

Used to save the photos you take into your photo library. This is an add-only permission. The App does not request permission to browse or read the existing contents of your photo library.

Permissions the App does NOT request

• Read access to your photo library (NSPhotoLibraryUsageDescription is not used)
• Location, microphone, contacts, calendar, motion-activity recording, notifications, or tracking authorization (App Tracking Transparency)

5. Photos You Select for "Overlay Shot"

The "Overlay Shot" feature (kasane-dori), which overlays a previously taken photo semi-transparently so you can match its composition, uses the standard iOS photo picker (PHPickerViewController).

• That picker is presented by iOS outside of the App's own process; the App is not browsing your photo library. No photo library read permission is required, and no permission prompt appears.
• The App receives only the single image you choose, at the moment you choose it.
• That image is downscaled and held only in the App's working memory so it can be drawn over the viewfinder. It is never written to storage and never transmitted. It is discarded when you turn the overlay off or quit the App.
• The overlaid image never appears in the photo you capture.

6. Where Your Photos Are Saved

Photos you capture are saved only to your iPhone's photo library. The App maintains no photo storage of its own and keeps no copy. Once saved, a photo is under your control alone and cannot be read back by the App.

7. Settings Stored in the App

The App stores the following settings only on your device (in iOS UserDefaults). They contain no personally identifiable information and are never transmitted. Deleting the App deletes them.

• Advice display on / off
• Recommended finish on / off
• Auto-shutter on / off
• Whether the chosen reference outline is drawn over the viewfinder
• Selected grid (composition guide) type
• Whether each first-run explanation (onboarding, overlay shot, readiness ring) has already been shown

8. Advertising, Analytics, and Third Parties

• The App displays no advertising and includes no advertising SDK.
• The App includes no analytics or behavioral-tracking SDK of any kind.
• The App has no third-party library or SDK dependencies — it uses only the frameworks Apple ships with iOS.
• Because no data is collected, there is no data to share with or sell to third parties.
• The App does not track you and does not link information across other companies' apps or websites.

9. Children's Privacy

The App is not directed at any particular age group. Because it collects no personal information from any user, it collects none from children either.

10. Your Rights

Because the App neither collects nor holds personal data, the developer holds no data subject to access, correction, or deletion requests. The on-device settings can be changed at any time in the App's settings screen, or erased entirely by deleting the App.

11. Changes to This Policy

If a future release changes how the App handles data, this page will be updated and the "Last updated" date revised. Material changes will also be noted in the App's release notes.
