StickerBoard (hereinafter “the App”) respects user privacy to the fullest extent. This Privacy Policy explains how information is handled in the App.
Basic Policy

All data such as stickers and boards created by users is stored solely on the device. However, crash reports (error logs generated when a crash occurs) may be automatically transmitted for the purpose of improving app quality (see the “Crash Reports” section for details).

- Saved in PNG format in the device’s Documents folder
Metadata

- Board names, placement information, and background settings
- Filter and border settings
App Settings

- Subscription (Pro Plan) status cache
All of this data is stored on the device and is never transmitted externally via the network.
Camera Usage

- Camera access can be disabled at any time in iOS Settings
Photo Library Usage
The App may request access to the photo library for photographing stickers or saving board and sticker images.
- Images selected from the photo library are used solely for sticker extraction processing
- Exported board images or individual sticker images are saved to the photo library upon user request
- Photo library images are never transmitted externally
Board and Sticker Sharing
When you use the board sharing or sticker sharing feature, content can be shared with external apps via the OS standard share sheet.
- Data shared: Board or sticker image data only
- External transmission: When you choose to share to an SNS, messaging app, or other service, the content is handed off to that app
- Privacy policy of destination: How data is handled after being handed off is governed by the privacy policy of the app the user selects
- No personal information: Shared images do not contain personal information such as names or location data
Local Network Usage (Sticker Exchange Beta)
The App’s sticker exchange feature (beta) requests access to the local network to directly exchange stickers with nearby users.
- Technology used: Direct device-to-device communication (Wi-Fi / Bluetooth) using Apple’s MultipeerConnectivity framework
- Data transferred: Sticker images only. No personal information such as names, location data, or account information is included
- External server transmission: Sticker exchange data is transferred directly between devices without going through external servers
- When used: Only when the sticker exchange screen is opened from “Beta Features” in Settings
- Revoking permission: Local network access can be disabled at any time in iOS Settings > StickerBoard
Subscriptions (In-App Purchases)
Pro Plan subscription purchases are processed through Apple’s App Store.
- Payment information is managed by Apple; the developer does not have access to it
- Subscription status is cached on the device
- For Apple’s privacy policy, please see Apple Privacy Policy
Crash Reports
The App uses a crash reporting service to improve quality.
- Service used: Google Firebase Crashlytics
- Information collected: Error logs when the app crashes (force quits), device model, OS version, and app version
- Information not collected: Personal data such as user-entered information, sticker images, and board contents are not collected
- Data destination: Servers operated by Google LLC (United States)
- Purpose: Used solely to identify the cause of crashes and improve app stability
- Opt-out: You can stop sharing crash data by going to iOS Settings > Privacy & Security > Analytics & Improvements > turning off “Share with App Developers”
For Firebase Crashlytics’ privacy policy, please see Google Privacy Policy.
Third-Party Services
The App uses the following third-party services:
- Apple StoreKit: Used for subscription management. Apple’s privacy policy applies.
- Google Firebase Crashlytics: Used for crash reporting. Google’s privacy policy applies.
The App does not use advertising SDKs or analytics tools.
Data Sharing with Widget
The App shares data between the main app and the widget to display boards using iOS’s widget feature.
Data Shared
- Board snapshot images: Board images for display in the widget (JPEG format)
- Board metadata: Information such as board name, number of stickers, and last updated date (JSON format)
How Data Sharing Works
- Uses Apple’s App Group mechanism
- Data is stored in a shared container on the device and is shared only between the main app and the widget
- Data is never transmitted via external servers or networks
Data Management
- Widget data is automatically updated and deleted in sync with board creation, editing, and deletion
- Uninstalling the app also deletes the shared widget data
Data Deletion
- Sticker and board data can be deleted at any time through in-app operations
- Uninstalling the app deletes all stored data
- If using iCloud backup, data may be included in backups
Children's Privacy
Since the App does not collect personal information, it can be used safely by children. We do not intentionally collect personal information from children under the age of 13.
Changes to This Privacy Policy
This Privacy Policy may be updated as needed. In the event of significant changes, you will be notified when the app is updated.
