Privacy Policy


Last updated: September 2026

Effective date: When this revision is published on this page.

AAAI Studio LLC ("we," "our," or "us") operates the Mangii mobile application and website (collectively, the "Service"). This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our Service.

1. Age and consent

Mangii is a general-audience manga creation and reading service. Store age ratings describe content suitability and may vary by region. You must comply with applicable laws and any age or consent requirements that apply to your use of the Service. Where applicable law requires parental permission or consent, it must be obtained before the relevant use or data processing. Parents or guardians may contact us about a child's account or personal data at support@aaai.studio.

2. Information We Collect

2.1 Information You Provide

  • Account Information: Email address, display name, and profile picture when you create an account via Google Sign-In or Apple Sign-In
  • User Content: Text prompts you enter to generate images, manga stories you create, and any content you upload (such as profile avatars and optional reference images used for generation)
  • Communications: Messages you send to our support team
  • Transaction Information: Purchase history for subscriptions and credit packs (payment processing is handled by Apple App Store, Google Play Store, or Stripe for web purchases)

2.2 Information Collected Automatically

  • Device Information: Device type, operating system version, unique device identifiers
  • Usage Data: Features you use, actions you take, time and duration of activities
  • Log Data: IP address, browser type, pages visited, crash reports
  • Analytics Data: App usage events where optional analytics is enabled and you allow it; these events may be linked to your account identifier

2.3 Information from Third Parties

  • Authentication Providers: Google and Apple provide your email and profile information when you sign in
  • Payment Providers: Apple App Store and Google Play Store provide transaction confirmations

3. How We Use Your Information

We use the information we collect to:

  • Provide, operate, and maintain our Service
  • Process your transactions and manage your subscriptions
  • Generate AI-powered manga images based on your prompts
  • Store and display your created content
  • Send you technical notices, updates, and support messages
  • Respond to your comments, questions, and customer service requests
  • Monitor and analyze usage trends to improve our Service
  • Detect, prevent, and address technical issues and fraudulent activity
  • Enforce our Terms of Service and protect user safety

4. Third-Party Services and Data Sharing

We share your information with the following categories of third parties:

4.1 Service Providers

  • Firebase (Google): Authentication, database, cloud storage, analytics, crash reporting, and cloud functions
  • AI providers: OpenAI, Google Gemini, xAI, Replicate hosting Flux, and Alibaba Cloud Model Studio/DashScope Qwen process generation requests. A request may be routed between these providers as a fallback. See Section 12 for the information shared and your choices.
  • Cloudflare: Media storage, delivery, and cache services
  • Stripe: Web payment and subscription processing
  • Airbridge: Optional marketing attribution and campaign measurement, including account identifiers and purchase events when allowed
  • RevenueCat: Subscription and in-app purchase management
  • Google AdMob: Advertising services (for free tier users)

4.2 Legal Requirements

We may disclose your information if required by law, regulation, legal process, or governmental request.

4.3 Business Transfers

In connection with a merger, acquisition, or sale of assets, your information may be transferred to the acquiring entity.

We do not sell your personal information to third parties.

5. Advertising and Tracking

Our Service uses Google AdMob to display advertisements to free tier users. Advertising partners may process device identifiers and advertising activity. The iOS App Tracking Transparency permission controls tracking across other companies' apps and websites; it is separate from Mangii's optional analytics and marketing choices.

Where optional analytics is enabled, Firebase Analytics helps us understand feature use. Events may be associated with an account identifier before being summarized in reports. Firebase Analytics collection is currently disabled in the iOS app. Optional marketing measurement uses Airbridge only after your marketing choice and, on iOS, tracking permission allow it. You can withdraw optional choices in the app's privacy settings. After withdrawing marketing permission on iOS, re-enabling it takes effect after a fresh launch.

6. Data Retention

We retain your information for as long as:

  • Your account remains active
  • Needed to provide you with our Services
  • Required by law or for legitimate business purposes

Account deletion is processed in stages. The deletion screen shows whether cleanup is still pending or complete. Media removal, delivery-cache invalidation, and outstanding generation or payment work may take additional time; a pending request is not a completed deletion.

Deletion removes account content, including generated media and prompts, rather than retaining it for general service improvement. We retain limited billing, fraud-prevention, safety, and deletion-status records where needed to meet legal obligations, prevent repeated abuse, and demonstrate completion. These records do not preserve your deleted creative content. Contact support if a deletion request remains pending or you need information about retained records.

7. Data Security

We implement appropriate technical and organizational security measures to protect your personal information, including:

  • Encryption of data in transit using TLS/SSL
  • Secure cloud infrastructure provided by Google Cloud Platform
  • Access controls and authentication requirements
  • Regular security assessments

However, no method of transmission over the Internet or electronic storage is 100% secure. While we strive to protect your information, we cannot guarantee absolute security.

8. Your Rights and Choices

8.1 Account Information

You may update, correct, or delete your account information at any time through the app settings.

8.2 Account Deletion

Request deletion through Account settings in the app or at mangii.ai/account/delete. You may need to verify your identity. The screen keeps the request status available while server cleanup continues. Clearing local data does not cancel an accepted server deletion. Deleting a Mangii account does not itself cancel an Apple or Google subscription; manage it separately in the relevant store. Store cancellation is not required to submit deletion.

8.3 Marketing Communications

You can opt out of push notifications through your device settings.

8.4 Advertising Preferences

On iOS, you can control ad tracking through the App Tracking Transparency prompt or in Settings > Privacy > Tracking. On Android, you can reset your advertising ID or opt out of personalized ads in Settings > Google > Ads.

9. International Data Transfers

Your information may be transferred to and processed in countries other than your country of residence, including the United States where our servers and service providers are located. These countries may have different data protection laws. By using our Service, you consent to such transfers.

10. European Users (GDPR)

If you are located in the European Economic Area (EEA), you have additional rights:

  • Access: Request a copy of your personal data
  • Rectification: Request correction of inaccurate data
  • Erasure: Request deletion of your data ("right to be forgotten")
  • Portability: Request transfer of your data to another service
  • Restriction: Request limitation of processing
  • Objection: Object to processing based on legitimate interests

Our legal basis for processing includes: performance of contract (providing the Service), legitimate interests (improving our Service, fraud prevention), and consent (marketing, analytics).

To exercise these rights, contact us at support@aaai.studio. You also have the right to lodge a complaint with your local data protection authority.

11. California Users (CCPA)

If you are a California resident, you have the right to:

  • Know what personal information we collect and how it is used
  • Request deletion of your personal information
  • Opt out of the sale of personal information (we do not sell your data)
  • Non-discrimination for exercising your privacy rights

To make a request, contact us at support@aaai.studio.

12. AI-Generated Content

Before AI generation, Mangii asks permission to send your prompt, reference images, stored context images, and optional voice-derived input to the AI providers listed in Section 4. Requests may use a fallback provider from that list. Declining blocks AI generation and voice input; reading remains available subject to the age and content-access rules. You can withdraw permission in privacy settings; withdrawal stops future generation requests and does not undo processing already performed. A material change to the disclosure requires a new choice.

Optional voice input uses Apple or Google operating-system speech recognition, separately from the AI providers above, and may process audio off device. We use moderation to reduce prohibited output, but automated systems can make mistakes. You can report unsafe output from the reader. Provider retention and processing are subject to the relevant provider's terms and our service arrangements; this policy does not promise that a provider keeps no data.

13. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of material changes by posting the new Privacy Policy in the app and updating the "Last updated" date. Your continued use of the Service after changes become effective constitutes acceptance of the revised policy.
