This Privacy Policy describes how Rika Hirayama (“we”, “us”, or “our”) handles information about users (“you”) in connection with the AMUU crochet pattern app (the “App”).
By using the App, you agree to the handling of information as described in this Privacy Policy.
Section 1. Scope
This Policy applies to information that we obtain through the App, as well as information collected by third-party services that are integrated into the App.
Section 2. Information We Collect
The App may collect the following types of information.
We do not actively collect information that directly identifies you as an individual (such as your name, physical address, or email address) through the App.
1. Information Automatically Sent During Use of the App
The following information may be automatically sent when you use the App:
- Device information (such as device model and OS version)
- App version
- Usage information (such as screen views and button tap logs)
- Crash information (such as error logs and stack traces)
- Approximate location information (at the country or region level)
- Advertising identifiers (such as Apple’s advertising ID)
This information is mainly collected through the following third-party services:
- Firebase Analytics / Firebase Crashlytics (provided by Google LLC)
- Google Mobile Ads SDK (AdMob) (provided by Google LLC)
- In-app purchase and subscription management services (Apple Inc. and, where applicable, third-party payment or subscription management providers such as RevenueCat Inc.)

- Purchase history (such as the type of plan purchased and its expiration date)
- Transaction IDs
- Subscription status (such as active or cancelled)
We may access such information through the payment platforms for purposes such as managing your subscription and preventing misuse.
However, we do not have access to your actual payment method details (for example, credit card numbers).
3. User-Generated Content
Crochet charts and other content that you create within the App are, in principle, stored locally on your device.
Some features (such as backup or sharing) may use OS-level or third-party services (such as iCloud or system sharing features). In such cases, the handling of information is governed by the privacy policies of those service providers.
Children’s Privacy
The App is not intended for children under the age of 13 (or the age defined as a child in your jurisdiction), and we do not knowingly collect personal information from children.
If you believe that a child has provided us with personal information, please contact us using the details in Section 10 so that we can take appropriate steps.
Section 3. Purposes of Use
We and the third-party services described above use the collected information primarily for the following purposes:
- To provide, maintain, and improve the App
- To investigate the causes of bugs or crashes and to improve quality
- To analyze usage and develop new features or improvements
- To deliver advertisements and measure their effectiveness
- To provide paid plans, confirm purchase status, and prevent fraudulent use
- To comply with applicable laws and respond to violations of terms of use
Section 4. Third-Party Sharing and Disclosure
We do not provide user information to third parties except in the following cases:
- When we have your consent
- When disclosure is required under applicable laws or regulations
- When it is necessary to protect a person’s life, body, or property and obtaining consent is difficult
- When the information is provided in a form that does not identify you as an individual, such as aggregated or statistical information
As noted above, the App includes SDKs provided by third-party services. These service providers may collect and use information about you under their own privacy policies.
Examples of such providers include:
- Google LLC (Firebase, AdMob, etc.)
- Apple Inc. (App Store, in-app purchases, etc.)
- Third-party subscription management providers such as RevenueCat Inc. (if and when used)
For details, please refer to the privacy policies on each provider’s official website.
Section 5. Data Security and Management
We implement appropriate and reasonable security measures to help prevent the leakage, alteration, or unauthorized access of user information.
However, due to the nature of communication and information systems, we cannot guarantee complete security.
We store collected information only for as long as necessary to fulfill the purposes described in this Policy, and we strive to delete or anonymize it without undue delay once it is no longer needed.
Section 6. Advertising
The App uses third-party advertising services (such as Google AdMob).
These services may use cookies, advertising identifiers, and similar technologies to display ads based on your App usage and other information.
You can manage personalized advertising settings or reset advertising identifiers through your device’s settings. Please refer to the help documentation of your OS for details.
Section 7. Analytics and Crash Reports
The App uses services such as Firebase Analytics and Firebase Crashlytics to collect and analyze information about App usage and crash events.
This information is mainly used for:
- Understanding which screens and features are used most frequently
- Identifying and fixing the causes of bugs and crashes
- Informing future feature and UI improvements
We do not use this information for the purpose of identifying you as an individual.
