Privacy Policy

Last updated: October 10, 2026

1. Introduction

YasaiDev (X: @YasaiDev, the “Developer”) considers the protection of users’ privacy in the mobile application “DoodleRise” (the “App”) to be important.

This Privacy Policy (the “Policy”) sets forth 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.

The App consists of two layers: core features (alarms, drawing, review, etc.) that can be used entirely on the device without account registration, and social features (friend groups, feed, comments, stamps, stories, gifts, notifications, etc.) that allow drawings to be shared within invite-only groups after optionally signing in. The scope of information collected differs depending on how far the User uses these features.

2. Handling of Personal Information

We handle the sign-in identifier, email address, and profile information needed to create and use an account when a User signs in. Even without sign-in, the third-party services described below may handle app or device identifiers for purchases, notifications, usage analytics, and advertising.

Only when a User signs in to use social features does the Developer handle the sign-in identifier and email address provided through Sign in with Apple or Google (including the private, undisclosed email address provided by Apple’s Private Relay when using Apple), as well as the profile information set by the User (display name, icon, and theme color).

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

Data Type	Managed By	Condition for Collection	Sharing / Disclosure
User Content (on-device drawing data)	User’s device only	Always on-device only	Not accessible to the Developer
Account information (sign-in identifier, email address)	The Developer	Only upon sign-in	Not disclosed to third parties. Disclosable/deletable upon the individual’s request
Profile (display name, icon, theme color)	The Developer	Only upon sign-in	Displayed to members of joined groups
Posted content (drawings and short messages posted to a group)	The Developer	Only when the User posts	Displayed only to members of joined groups. Automatically deleted within approximately 10 days at most
Groups / memberships, comments / stamps	The Developer	When using social features	Shared only among the members of that group
Push notification registration information	The Developer / OneSignal (iOS) / Firebase Cloud Messaging	When notification features are enabled	Used only for the purpose of delivering notifications
Payment information (credit cards, etc.)	Apple Inc. / Google LLC	Upon paid purchase	Managed by the App Store / Google Play. Not collected by the Developer
Purchase history / subscription status / gift balance	RevenueCat (linked to an anonymous app user ID / linked to the account ID after sign-in)	Upon paid purchase	Disclosable after identity verification
Usage data / app identifiers	The Developer / Firebase Analytics	Depending on settings and consent (opt-out available)	Used for usage analysis and quality improvement
Advertising data (IP address, device identifiers, ad interactions, diagnostics, etc.)	Google AdMob	When ads are used, depending on consent and device settings	Used for ad delivery, measurement, and fraud prevention

3. User Content

Illustrations and drawing data created by Users within the App (the “User Content”) are, by default, stored solely on the User’s device and are not transmitted to the Developer’s servers.

However, only when a User chooses to post User Content to a group through the social features will such content be stored by the Developer for the purpose of displaying it to the members of the joined group. The copyright to posted content belongs to the User, and the Developer will not use it for any purpose other than operating the App’s social features. For the sharing scope and retention period of posts, please refer to Section 6.

4. Data Stored on Your Device

The following data is stored only on the User’s device and, unless the User makes a post, is not transmitted to the Developer’s servers.

Illustrations drawn by the User (drawing data)
Data relating to core features, such as alarm settings and review records

5. Data We Collect

5.1 Usage Data and Device Information

To improve the App and enhance service quality, we collect the following usage data through services such as Firebase Analytics, depending on settings and consent. Analytics services use identifiers that distinguish app instances, so not all data is fully anonymous.

Usage Data: App usage frequency, feature usage, and diagnostic information such as crashes
Device Information: Technical information such as OS version, device model, language settings, and app identifiers

Opt-out: Users can disable the collection of usage data in the App’s settings screen. If you opt out, transmission of usage analytics data will stop. We use Google AdMob for advertising. Depending on consent and device settings, it handles IP addresses (which may be used to estimate general location), device identifiers such as advertising IDs, ad interactions, and diagnostic information for ad delivery, measurement, and fraud prevention. Consent forms are displayed where required. You can review and change advertising privacy choices through the privacy options shown in the App or your device settings. Usage analytics opt-out and advertising settings are managed separately.

Only when a User signs in to use social features do we collect and retain the following information.

Account Information: The sign-in identifier and email address provided through Sign in with Apple or Google (including the private, undisclosed email address provided by Apple’s Private Relay when using Apple)
Profile Information: The display name, icon, and theme color set by the User
Information Relating to the Use of Social Features: The groups joined, content posted (drawings and short messages), comments and stamps, and notification status

5.3 Purchase Information

In-app purchases and subscription management use a third-party service, RevenueCat, Inc. RevenueCat manages purchase history, subscription status, and the balance of gifts (Premium Tickets), linked to an app user ID (an anonymous identifier automatically generated from the device before sign-in, and the account identifier after sign-in).

Actual payment processing (credit card information, etc.) is handled through Apple Inc.’s App Store on iOS or Google LLC’s Google Play on Android, and neither the Developer nor RevenueCat directly obtains or retains payment information.

The App’s social features exist only within invite-only, closed groups. There is no mechanism for publishing to the general public, no public feed, and no indiscriminate user search or public discovery.

Sharing Scope: Content posted by a User, comments and stamps, and the profile are displayed only to the members of the groups that the User has joined. They are not disclosed to third parties outside the group.
Retention Period: Content posted to a group is displayed on the feed only for a limited period after posting, and is automatically deleted from the Developer’s storage within approximately 10 days at most from the time of posting.
Deletion: Users may delete their own posts at any time. If a User deletes a post, leaves or is removed from a group, or deletes their account, such content will no longer be viewable by the other members of that group.

7. Purpose of Use

Collected data is used only for the following purposes:

Improving App quality and fixing bugs
Providing and operating social features (sign-in, profile display, sharing content within groups, delivering notifications, etc.)
Responding to user support requests
Analyzing usage patterns and producing statistics
Delivering and measuring ads and preventing fraud

8. Provision to Third Parties

The Developer will not provide collected information to third parties except with the User’s consent or as required by applicable law.

However, the Developer may entrust the handling of data to the third-party service providers described below to the extent necessary to provide the App. In addition, usage data is used for the purpose of analysis necessary to improve the App’s quality.

9. Use of Third-Party Services

The App uses the following third-party services. Each of these services operates under its own respective privacy policy. The handling of data is governed by each service provider’s privacy policy.

Apple Inc.: App distribution, in-app purchase payment processing, and authentication via Sign in with Apple (payment information is managed by Apple Inc.)
Google LLC: Google sign-in, Android app distribution and Google Play payments, push notifications via Firebase Cloud Messaging, and advertising and consent management via Google AdMob (Privacy Policy)
Cloudflare, Inc.: Storage and delivery of data in the social features (accounts, profiles, posted content, etc.)
OneSignal: Delivery of iOS push notifications
RevenueCat, Inc.: Management of in-app purchases, subscriptions, and gifts
Analytics tools such as Firebase Analytics: App usage analysis depending on settings and consent (Firebase privacy information)

10. Data Storage and Management

Data relating to core features (drawing data, alarm settings, etc.) is stored exclusively on the User’s device. Unless the User makes a post, this data is not transmitted to the Developer’s servers.

Data relating to social features (accounts, profiles, posted content, etc.) is stored by the Developer only for signed-in Users, to the extent necessary to operate the service. As described above, posted content is automatically deleted within approximately 10 days at most.

When the App is deleted, all locally stored data on the device, such as drawing data and alarm settings, will be removed. The Developer cannot restore this data. Please note that deleting the App alone does not delete the account. If you wish to delete information associated with your account, please perform the account deletion operation within the App.

11. Data Security

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

12. User Rights

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

Users who do not sign in: The Developer cannot access on-device drawings or alarm settings. For data relating to purchases, analytics, or advertising, please also consult the settings described above and the relevant service providers.
Signed-in users: Since the Developer holds accounts, profiles, posted content, and the like, we will respond to requests for the disclosure, correction, deletion, or the like of such information. Users can perform much of this themselves through operations within the App, such as editing their profile, deleting posts, and deleting their account.

Regarding purchase information, only if a User can verify their identity through App Store or Google Play purchase records or similar means, we can respond to requests for disclosure of the purchase history linked to that user ID through RevenueCat.

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