Privacy Policy

1. Introduction

YasaiDev (X: @YasaiDev, the “Developer”) values the protection of users’ personal information and privacy in the mobile application “DoodleRise” (the “App”).

This Privacy Policy (the “Policy”) describes the types of information collected through the App, the purposes for which it is used, and how it is managed. By using the App, you are deemed to have agreed to the contents of this Policy.

2. Non-Retention of Personal Information

The App does not require account registration and does not collect or retain any personally identifiable information such as names, email addresses, or phone numbers. We also do not collect tracking identifiers such as IDFA (Identifier for Advertisers).

Therefore, it is not possible to identify any specific individual based on the data we hold.

The following table provides an overview of data handling in this App.

Data Type	Managed By	Link to Personal Info	Disclosure
Payment information (credit cards, etc.)	Apple Inc.	Managed by Apple	Via Apple
Purchase history / subscription status	RevenueCat (anonymous app user ID)	Not linked to name, etc.	Disclosable after identity verification via Apple receipt
Usage data	Us (anonymized)	Cannot identify individuals	Opt-out available (disable in settings). GDPR region users are shown a consent dialog on first launch
Personal information (name, email, etc.)	Not held by anyone	—	No data exists to disclose
User content (drawing data)	User’s device only	—	We have no access
iCloud backup	Apple Inc.	Only user can access	We have no means of access

3. User Content

The Developer does not collect any illustrations or drawing data (user content) created by users within the App. No functionality to transmit user content to the Developer’s servers, in any form including anonymized form, is implemented in the App. The App does not have any data upload functionality to the Developer whatsoever.

All user content is stored exclusively on the user’s device.

4. Data Stored on Your Device

The following data is stored only on the user’s device and is never transmitted to the Developer’s servers.

• Illustrations drawn by the user (drawing data)

5. iCloud Backup

If the user has iCloud Backup enabled, app data may be stored as part of the device backup. However, this is a service provided by Apple Inc., and only the user themselves can access that data. The Developer has no means to access data stored in iCloud Backup.

6. Data We Collect

To improve the App and enhance service quality, we collect only the following anonymized usage data in accordance with this Policy. This data cannot be linked to any specific individual.

6.1 Usage Data and Device Information

• Usage Data: Anonymized analytics data such as app usage frequency, feature usage, and crash logs
• Device Information: Technical information such as OS version, device model, and language settings

6.2 Purchase Information

In-app purchases and subscription management use a third-party service, RevenueCat, Inc. RevenueCat manages purchase history and subscription status linked to an anonymous app user ID (an identifier automatically generated from the device).

This app user ID is not linked to the user’s name, email address, phone number, or any other personal information. Actual payment processing (credit card information, etc.) is handled through Apple Inc.’s App Store, and neither we nor RevenueCat directly obtain or retain payment information.

Disclosure of purchase information: If a user wishes to have their purchase information disclosed, we can provide the purchase history linked to the anonymous user ID through RevenueCat, provided the user can verify their identity through Apple-issued receipt information or similar means.

Opt-out: Users can disable usage data collection in the App’s settings. If you opt out, transmission of anonymized analytics data will be stopped.

7. Purpose of Use

Collected anonymized usage data is used only for the following purposes:

1. Improving App quality and fixing bugs
2. Responding to user support requests
3. Analyzing usage patterns (as anonymized statistical data)

8. Third-Party Sharing

Since the Developer does not hold personally identifiable information, we do not share personal information with third parties.

Anonymized usage data may be shared with third parties only in the following cases:

1. When required by applicable law
2. When using analytics services necessary for improving App quality (anonymized data only)

9. Third-Party Services

The App may use the following third-party services. These services operate under their own respective privacy policies:

• Apple App Store: App distribution and in-app purchase processing (payment information is managed by Apple Inc.)
• RevenueCat, Inc.: Management of in-app purchases and subscriptions (manages purchase history based on anonymous app user ID; no linking to personal information)
• Analytics Tools: App usage analysis (anonymized data only)

Data collection by these services is governed by the respective service providers’ privacy policies.

10. Data Storage and Management

All drawing data created by users is stored exclusively on the user’s device. No upload functionality to the Developer’s servers exists in the App.

When the App is deleted, all locally stored data — including drawing data, alarm settings, and other local data — will be permanently removed. The Developer cannot restore this data. Restoration from iCloud Backup is the user’s own responsibility and must be done through Apple Inc.’s service.

11. Data Security

The Developer implements reasonable technical and organizational security measures to prevent leakage, loss, or damage of collected anonymized usage data.

12. User Rights

Under applicable law, users have the right to request disclosure, correction, deletion, or suspension of use of their personal information.

However, as stated above, the Developer does not hold personally identifiable information. Therefore, even if a request for disclosure is received, there is no personal data to provide. In the event of such a request, we will explain the status of data we hold and respond accordingly.

Regarding purchase information, if the user can verify their identity through Apple-issued receipt information or similar means, we can disclose purchase history linked to the anonymous user ID through RevenueCat.

Please submit inquiries through the in-app contact feature or the contact form on the website.

13. For EU/EEA Residents (GDPR Compliance)

For users residing in the European Union (EU) or the European Economic Area (EEA), the following rights are guaranteed under the EU General Data Protection Regulation (GDPR):

1. Right to Data Portability
2. Right to Restriction of Processing
3. Right to Object
4. Right to Withdraw Consent
5. Right to Lodge a Complaint with a Supervisory Authority

However, the App does not require account registration, does not collect tracking identifiers such as IDFA, and all data collected is exclusively anonymized usage data. Since the Developer does not hold any data linked to a specific individual, there is physically no personal data available to disclose or delete in response to requests based on the above rights. In the event of such a request, we will inform you accordingly and respond in good faith.

The Developer collects only the minimum necessary data in accordance with GDPR requirements, and data of EU/EEA residents is processed with appropriate safeguards in place.

14. Children’s Privacy

The App does not intentionally collect personal information from children under the age of 13. The App does not have any functionality to collect personally identifiable information in the first place.

15. Changes to Policy

The Developer may amend this Policy in response to changes in applicable law or service content. Users will be notified of significant changes within the App or on the website. Continued use of the App after any amendments constitutes the user’s agreement to the amended Policy.

16. Language

This Policy was originally prepared in Japanese, which shall be the authoritative version. In the event this Policy is translated into another language and there is any contradiction or discrepancy between the Japanese version and a translation, the Japanese version shall prevail.

17. Governing Law
