MononoMori Privacy Policy

  • Effective Date: August 1, 2025
  • Last Updated: September 19, 2026

Hello, I am the developer of “MononoMori.”

Thank you for choosing MononoMori. When creating this little world, I had one core belief that I hold dear: “Your life’s records belong to you, and you alone.”

I firmly believe that privacy is best protected by building an architecture that minimizes data collection and respects user ownership. This policy explains clearly and transparently how MononoMori handles and protects your data.

Article 1 (Core Principles & Data Handling)

MononoMori does not collect or store personal information for advertising, marketing, or user profiling. Most of the content you create in the app (such as items, spaces, photos, tags, and notes) remains on your local device or in your private iCloud account. MononoMori does not operate proprietary user accounts or maintain private member databases to store your personal inventory. Certain technical data, identifiers, or content may be processed by trusted third-party services only when you actively use specific features, such as AI recognition, cloud sync, crash diagnostics, and in-app purchases.

Article 2 (Data Storage & iCloud Sync)

  1. Local Storage: All inventory, space, and category content you create is stored locally on your device within the app’s secure sandbox.
  2. iCloud Synchronization: You may optionally enable iCloud Sync. Data stored through Apple’s iCloud and CloudKit services is encrypted in transit and at rest. Additional end-to-end encryption may be available depending on your iCloud security settings (such as Apple’s Advanced Data Protection) and Apple’s supported protections. MononoMori does not have access to your Apple Account credentials or your private iCloud encryption keys. You can enable or disable iCloud sync at any time from your device or app settings.

Article 3 (AI Smart Recognition Features)

When you actively use the “AI Smart Scan / Recognition” feature, the selected images and information necessary to complete recognition are sent via an encrypted HTTPS connection to our third-party AI service providers for real-time analysis to assist in automatically identifying items and filling in relevant details.

  • On-Demand Processing: Data is transmitted and processed only when you explicitly trigger the AI recognition feature. When you do not actively use this feature, your item photos will not be sent to third-party AI services for AI recognition.
  • No Advertising or AI Model Training: We do not use your submitted images or related information for advertising, user profiling, or training AI models.
  • Data Minimization and Retention: We transmit only the data necessary to complete the AI recognition and minimize the retention of related data. MononoMori does not store your submitted photos or AI recognition results as long-term data. The processing and retention of received data by third-party AI service providers are governed by their respective applicable terms of service and privacy policies.

Article 4 (Crash Diagnostics & App Stability)

To ensure app stability, identify technical issues, and resolve crashes, we may process technical diagnostic data:

  1. Apple Diagnostics: If you have consented to “Share With App Developers” in your iOS system settings, Apple provides aggregated, non-identifying crash logs and usage metrics in accordance with Apple’s Privacy Policy.
  2. Firebase Crashlytics: We may use Firebase Crashlytics (provided by Google) to diagnose crashes and improve app performance. These services may process technical information such as crash stack traces, app version, operating system version, device model, and randomly generated installation or session identifiers (including Crashlytics Installation UUID, Firebase Installation ID, and Firebase session ID). These identifiers are used to associate crash reports with an app installation and are not used by MononoMori for advertising or cross-service behavioral profiling.

Article 5 (In-App Purchases & Subscription Management)

All payment processing for MononoMori Pro purchases and subscriptions is handled through Apple’s App Store and StoreKit. MononoMori does not collect, receive, or store your credit card number, bank account information, or other payment card details. Payment transactions and refund requests are subject to Apple’s applicable terms and privacy policy.

To manage subscription status, validate purchases, restore purchased entitlements, and provide subscription-related functionality, MononoMori uses RevenueCat, a third-party subscription management service.

RevenueCat may process purchase and subscription information, such as Apple transaction or receipt information, product and entitlement information, subscription status, and a randomly generated anonymous App User ID. It may also process limited technical information, such as device type and operating system, as necessary to provide its services.

MononoMori does not use this information for advertising, targeted advertising, or user profiling. Information processed by RevenueCat is subject to RevenueCat’s Privacy Policy.

Article 6 (Third-Party Services)

MononoMori uses certain third-party services to provide specific functionality:

These services process information necessary to provide their respective functions, subject to their own privacy policies and applicable terms.

Article 7 (User Control & Data Deletion)

You have complete control over your personal data:

  • You can edit, export, or delete any item, space, or record directly within the app at any time.
  • Deleting the app permanently removes all locally stored data from your device sandbox.
  • If you use iCloud Sync, you can manage or delete synced data directly through your iOS iCloud storage settings.

Article 8 (Children’s Privacy)

MononoMori is a general-audience app and is not specifically directed to children. We do not knowingly collect personal information from children in violation of applicable law. Where applicable law requires parental or guardian consent for the processing of a child’s personal data, we will comply with those requirements.

Article 9 (External Links)

The app and website may contain links to external websites that are not managed by us. We are not responsible for the privacy practices or content of these external sites. Please review the privacy policies of any linked websites.

Article 10 (Changes to This Policy)

If there are any changes to this Privacy Policy, we will notify you through the app or on our official website by updating the “Last Updated” date.

Article 11 (Governing Law)

This Privacy Policy shall be governed by the laws of Japan. This provision does not limit any mandatory rights or protections available to you under the laws applicable to your place of residence.
