Privacy Policy

This Privacy Policy describes how user information is handled in the disaster preparedness set management application "Sonamet" (hereinafter referred to as "this App"). We prioritize protecting user privacy and are committed to transparent information management.

1 Information Collected and Storage Methods

This App handles the following information through the specified methods to provide and improve services:

(1) Locally Stored Device Data

User inputs—including family composition data, stockpile and carry-on item lists, item names, quantities, expiration dates, storage locations, notes, and item photos—are stored exclusively in local storage on your device. This data is never transmitted to or stored on our external servers.

(2) Cloud Backup Data

When backup or synchronization features are enabled by the user, data is stored in your personal cloud storage service (such as iCloud). This data remains in your personal cloud storage and is not directly accessed or retrieved by us.

(3) Payment and Subscription Status Information

In-app purchase systems are utilized to verify purchase status, restore purchases, and manage licenses for the paid subscription plan "Sonamet Pro". Anonymous identifiers and purchase histories are referenced through this system, but payment card details are never collected or stored by this App.

(4) Information Related to Advertising

This App uses third-party advertising services (such as Google AdMob) for displaying advertisements. Ad identifiers (IDFA / AAID), IP addresses, and technical device information may be collected and processed by ad providers for relevant ad delivery and fraud prevention. On iOS, permission is requested via Apple's App Tracking Transparency (ATT) framework.

(5) Usage Analytics and Diagnostics

Third-party analytics services may be used to improve user experience, optimize performance, and diagnose crashes. Anonymous usage statistics and error logs are collected, without including personally identifiable information or user-entered stockpile notes.

(6) Camera and Photo Library Access

Permissions for the camera and photo library are requested solely for capturing or selecting photos associated with items. The resulting image files are saved locally on your device and are never viewed, accessed, or collected by the developer.

2 Purpose of Use

Collected or processed information is utilized for the following purposes:

  • Providing core app functions, such as calculating household stockpile and carry-on bag recommendations
  • Executing local reminder notifications (expiration alerts, low-stock reorder points, periodic maintenance, and Disaster Preparedness Day)
  • Verifying purchases, restoring transactions, and unlocking premium features for "Sonamet Pro"
  • Optimizing advertisement delivery and serving non-intrusive ads (Free version)
  • Improving application quality, user experience, and analyzing software bugs or crashes

3 Local Notifications

All reminder notifications (expiration warnings, inventory threshold alerts, periodic checkups, and Disaster Preparedness Day reminders) are handled locally by your device's internal functions (Local Notifications).

No personal data or device tokens are transmitted to external push notification servers. You may toggle notifications on or off at any time via your device settings or the app's settings screen.

4 Third-Party Services and Disclosure

We do not sell, disclose, or provide personal information to third parties without user consent, except as required by applicable laws and regulations.

As specified in this policy, technical data may be processed through third-party services for advertising, purchase verification, and analytics.

5 Changes to Privacy Policy

We reserve the right to modify this Privacy Policy to reflect changes in legislation or app functionalities. Revised policies become effective immediately upon being published on this website.
