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.
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.
We use the information we collect to:
We share your information with the following categories of third parties:
We may disclose your information if required by law, regulation, legal process, or governmental request.
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.
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.
We retain your information for as long as:
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.
We implement appropriate technical and organizational security measures to protect your personal information, including:
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.
You may update, correct, or delete your account information at any time through the app settings.
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.
You can opt out of push notifications through your device settings.
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.
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.
If you are located in the European Economic Area (EEA), you have additional rights:
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.
If you are a California resident, you have the right to:

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.
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.
If you have questions, concerns, or requests regarding this Privacy Policy, please contact us:
We will respond to your inquiry within 30 days.
