Migo Lingo Privacy Policy

**Last Updated: September 26, 2026**

Migo Lingo respects the privacy of its users. This Privacy Policy explains how information is accessed, stored, processed, and otherwise handled when users interact with the Migo Lingo mobile application ("Application").

Migo Lingo is a language-learning application providing vocabulary, grammar, pronunciation, listening, reading, speaking, interactive exercises, and optional AI-assisted language-learning features.

## 1. No Account and No Migo Lingo Learning-Data Backend

Migo Lingo does not require users to create an account.

Migo Lingo does not operate its own backend server, user-account database, or cloud storage service for storing users' learning progress or normal Application state.

Information required to maintain normal Application functionality is generally stored locally on the user's device.

Depending on the features used, locally stored information may include:

- Optional user-provided name

- Learning progress

- Completed lessons

- Scores and achievements

- Learning preferences

- Favorite words

- Application settings

- Subscription-entitlement state required for Application functionality

- Other information required to maintain the user's local Application state

Migo Lingo does not upload locally stored learning information to its own servers because Migo Lingo does not operate a backend service for receiving or storing such information.

Migo Lingo does not sell or rent users' locally stored learning information.

Third-party services and platform providers integrated into the Application may independently process certain information as described below.

## 2. Local Data and Application Deletion

Because Migo Lingo does not maintain a backend or cloud database containing users' learning progress, Migo Lingo does not maintain a server-side backup of locally stored learning data.

Local Application data generally remains on the user's device until it is removed by the user, the Application is deleted, Application data is cleared, the device is reset, or the operating system otherwise removes the data.

Deleting Migo Lingo or clearing its data may therefore permanently remove locally stored learning progress, preferences, and settings.

Migo Lingo cannot restore locally stored learning data that no longer exists on the user's device.

Deleting the Application does not automatically cancel an active subscription. Subscriptions must be managed or cancelled through the applicable App Store or Google Play subscription-management system.

## 3. AI Tutor

Migo Lingo may provide an optional AI Tutor designed specifically for foreign-language learning and practice.

Depending on available functionality, the AI Tutor may assist with:

- Conversation practice

- Vocabulary practice

- Grammar practice and correction

- Sentence practice and correction

- Speaking and language practice

- Role-playing

- Everyday conversation scenarios

- Travel-related language practice

- Language practice appropriate to the user's selected level

The AI Tutor is an educational language-learning feature and is not intended to provide medical, legal, financial, psychological, emergency, or other professional advice.

Generative AI may produce inaccurate, incomplete, inappropriate, unexpected, or otherwise incorrect output. Users should evaluate AI-generated content accordingly and should not rely on the AI Tutor for decisions outside language learning.

## 4. On-Device AI Processing

Migo Lingo uses separate platform-supported on-device generative AI technologies for supported AI Tutor functionality on iOS and Android.

### iOS — Apple Foundation Models

On supported Apple devices and operating-system versions, Migo Lingo uses Apple's Foundation Models framework and Apple's system language model made available through Apple Intelligence to provide AI Tutor functionality.

For the current iOS AI Tutor implementation, AI Tutor prompts and generated responses are processed using Apple's on-device system language model through the Foundation Models framework.

Migo Lingo does not send AI Tutor prompts or generated responses to OpenAI, Google Gemini cloud services, Anthropic, or any other third-party AI provider for AI inference.

Migo Lingo does not operate a remote AI inference backend and does not upload AI Tutor conversations to a Migo Lingo server for AI processing.

AI Tutor availability on iOS depends on factors such as compatible Apple hardware, operating-system version, Apple Intelligence and Foundation Models availability, supported languages, system configuration, and other Apple platform requirements.

### Android — ML Kit GenAI and Gemini Nano

On supported Android devices, Migo Lingo uses Google's ML Kit GenAI Prompt API, powered by Gemini Nano through Android's on-device AI infrastructure.

For the current Android AI Tutor implementation, supported AI Tutor input, model inference, and generated output are processed locally on the user's device through the applicable on-device technology.

Migo Lingo does not send AI Tutor prompts or generated responses to cloud-hosted Gemini services, OpenAI, Anthropic, or any other third-party AI provider for AI inference.

Migo Lingo does not operate a remote AI inference backend for the Android AI Tutor implementation.

AI Tutor availability on Android depends on factors such as compatible Android hardware, operating-system and system-service support, Gemini Nano model availability, supported functionality, Application version, language, system configuration, and other platform requirements.

### Migo Lingo AI Data Handling

Migo Lingo does not operate its own remote AI server for the on-device AI Tutor implementations described above.

Migo Lingo does not send AI Tutor prompts or generated responses to third-party AI providers for remote AI inference.

Migo Lingo does not upload AI Tutor conversations to its own servers for AI processing or permanent storage.

AI Tutor conversation content may be maintained temporarily within the Application as necessary to display and continue an active conversation.

Because these AI technologies are provided through the user's operating-system platform, their availability, model versions, technical behavior, and supported capabilities may change when Apple, Google, or the device manufacturer updates the relevant technology.

## 5. Sensitive and Personal Information in AI Tutor

Users should not provide sensitive, confidential, or unnecessary personal information to the AI Tutor.

Users should avoid entering information such as:

- Passwords or authentication credentials

- Banking or payment information

- Government identification numbers

- Private medical or health information

- Highly sensitive personal information

- Confidential business information

- Private information about another person without permission

The AI Tutor is intended for language-learning conversations and practice, not for storing or processing sensitive information.

## 6. Microphone and Speech Recognition

Migo Lingo may request microphone and speech-recognition permissions for features such as pronunciation practice, speaking exercises, and voice input.

Microphone access is used when the user actively uses functionality requiring voice input.

Users can control microphone and speech-recognition permissions through their device settings.

Migo Lingo does not operate its own backend server for recording, receiving, or storing users' microphone audio.

Speech recognition may be performed on-device or through speech-recognition technology provided by the operating system, platform provider, or device manufacturer, depending on the user's device, operating system, language, configuration, and feature being used.

Where a platform provider independently processes speech-recognition information, that processing is subject to the provider's applicable privacy practices and terms.

## 7. Text-to-Speech

Migo Lingo may use Text-to-Speech functionality provided by the user's device or operating system to pronounce words, sentences, stories, or other learning content and to support pronunciation and listening practice.

Text-to-Speech availability, voices, and processing may vary according to the user's device, operating system, installed voices, language, and system configuration.

## 8. Advertising — Google AdMob

Migo Lingo may use Google AdMob to display advertisements to users who are not entitled to an ad-free Premium experience.

Although Migo Lingo does not operate its own backend for storing users' learning progress, Google AdMob and related Google Mobile Ads technologies may independently process certain information in connection with advertising, measurement, security, fraud prevention, analytics, or related functionality.

Depending on the platform, Application configuration, user's settings, consent choices, region, applicable law, and advertising configuration, such information may include:

- Device and technical information

- IP address

- Advertising identifiers or other applicable device identifiers

- Advertising and interaction information

- Diagnostic or crash information

- Application performance information

- Other information processed by Google Mobile Ads as described in Google's applicable documentation and privacy policies

The exact information processed may depend on the Google Mobile Ads SDK version, enabled features, consent status, platform, and configuration.

Migo Lingo does not sell users' locally stored learning information to advertisers.

Google's independent processing of information is governed by Google's applicable privacy policies, terms, and consent requirements.

Premium users may receive an ad-free experience while an eligible Premium entitlement remains active.

## 9. Third-Party and Platform Services

Depending on the platform, device, and Application version, Migo Lingo may rely on technologies or services provided by platform providers or third parties, including:

- Apple Foundation Models for supported on-device AI functionality on iOS

- Google ML Kit GenAI APIs and Gemini Nano for supported on-device AI functionality on Android

- Operating-system speech-recognition services

- Operating-system Text-to-Speech services

- Google AdMob and Google Mobile Ads technologies for advertising

- Apple App Store and StoreKit for in-app purchases and subscriptions on iOS

- Google Play and Google Play Billing for in-app purchases and subscriptions on Android

These technologies and services may have their own technical requirements, privacy practices, terms, and data-processing behavior.

Migo Lingo's lack of its own backend for users' learning progress does not mean that third-party advertising, billing, operating-system, or platform services cannot independently process information necessary to provide their respective functionality.

## 10. Purchases, Subscriptions, and Billing

Migo Lingo may offer optional Premium subscriptions and other in-app purchases through the official application marketplace associated with the user's device.

On iOS, purchases and subscriptions are processed through the Apple App Store and StoreKit.

On Android, purchases and subscriptions are processed through Google Play and Google Play Billing.

Migo Lingo does not directly collect, process, or store users' full payment-card numbers, bank-account details, or other payment-method credentials. Payment information and billing transactions are handled by the applicable app-store provider according to that provider's terms and privacy practices.

To determine whether Premium features should be available, restore previous purchases, and reflect the current subscription entitlement, the Application may receive or access limited purchase-related information supplied by the applicable platform.

Depending on the platform, this information may include:

- Purchased product or subscription identifiers

- Purchase or transaction status

- Current subscription or entitlement status

- Renewal or expiration information where made available by the platform

- Cancellation, refund, or revocation status where made available by the platform

- Store-provided transaction, purchase, receipt, or purchase-token information necessary to provide, verify, maintain, or restore access

Migo Lingo does not currently operate its own backend server for storing users' subscription or purchase records.

Limited subscription-entitlement information may be processed or cached locally on the user's device where necessary to provide Premium access and maintain Application functionality.

The applicable app-store provider may independently retain and process purchase, billing, payment, transaction, tax, fraud-prevention, and account information in accordance with its own privacy policy and terms.

Users can manage or cancel an active subscription through the subscription-management functionality provided by the applicable app store.

Where supported by the platform and Application, Migo Lingo may provide controls or links that direct users to the applicable subscription-management options.

Deleting Migo Lingo does not automatically cancel an active subscription. Subscription cancellation must be completed through the applicable app-store subscription-management system.

## 11. Children's Privacy

Migo Lingo may be used by users of different ages, subject to the Application's applicable age rating, platform requirements, local laws, and parental or guardian supervision where appropriate.

Migo Lingo does not require users to create an account and does not operate its own server-side database for collecting children's learning profiles.

Parents and guardians are encouraged to supervise children's use of mobile applications and AI-assisted functionality and to review the privacy information applicable to the Application and relevant platform or third-party services.

Where required by applicable law or platform policy, Migo Lingo may apply appropriate protections, restrictions, consent mechanisms, advertising configurations, or limitations for younger users.

## 12. Data Security

Migo Lingo is designed so that users' normal learning progress and Application state are generally stored locally rather than in a Migo Lingo-operated cloud database.

Supported AI Tutor functionality described in Section 4 uses applicable platform-provided on-device AI technologies.

Migo Lingo may also store limited Premium entitlement state locally to determine whether applicable Premium functionality should be available.

Users are responsible for maintaining reasonable security of their devices, including device access controls, operating-system updates, and other available security protections.

No method of electronic storage or processing can be guaranteed to be completely secure.

Third-party and platform providers are responsible for the security of information independently processed through their respective services, subject to their applicable terms and policies.

## 13. Data Retention and Deletion

Migo Lingo does not maintain a server-side user account or database containing users' normal learning progress.

Locally stored Application data generally remains on the device until:

- The user removes it

- Application data is cleared

- The Application is deleted

- The device is reset

- The operating system otherwise removes the data

Migo Lingo does not maintain its own server-side archive of AI Tutor conversations processed through the on-device AI implementations described in this Privacy Policy.

Temporary conversation state maintained by the Application may be removed when the applicable session ends, Application data is cleared, or the Application is removed, depending on the implementation and device behavior.

Limited locally cached subscription-entitlement information may remain on the device as part of the Application's local state until it is replaced, cleared, the Application is removed, or the operating system otherwise removes the data.

Authoritative purchase and subscription records maintained by Apple or Google are subject to the applicable platform provider's own retention, billing, and account-management practices.

Third-party services such as Google AdMob and platform services may have independent retention and deletion practices governed by their respective policies.

## 14. User Choices and Permissions

Users can control certain Application functionality through their device, operating-system, and applicable app-store settings.

Depending on the device and platform, users may be able to:

- Allow or deny microphone access

- Allow or deny speech-recognition access

- Adjust advertising or privacy preferences

- Manage applicable consent choices

- Restore eligible purchases through the Application where supported

- Manage or cancel subscriptions through the applicable App Store or Google Play subscription settings

- Clear local Application data

- Delete the Application and its locally stored data

Disabling certain permissions may prevent related features from functioning correctly.

Because Migo Lingo does not maintain user accounts or a server-side learning database, there is no Migo Lingo account containing learning progress that users need to separately delete.

Deleting local Application data or deleting the Application does not necessarily delete purchase or subscription records maintained independently by Apple or Google.

## 15. International and Regional Privacy Requirements

Migo Lingo may be made available in multiple countries and regions.

Privacy, consent, advertising, children's privacy, payment, and data-protection requirements may differ by jurisdiction.

Where required, Migo Lingo may use platform or advertising-service consent mechanisms, limit certain functionality, or apply other measures intended to comply with applicable legal and platform requirements.

App-store providers and other third-party services may independently apply additional regional requirements relating to billing, taxation, consent, advertising, privacy, or data processing.

## 16. Access to This Privacy Policy

This Privacy Policy is intended to be available:

- Within Migo Lingo through the appropriate Application settings or information section

- Through the applicable app-store listing where required

- On the publicly accessible web page where this Privacy Policy is published

## 17. Changes to This Privacy Policy

This Privacy Policy may be updated from time to time to reflect changes to Migo Lingo, its functionality, Premium subscriptions, supported AI technologies, third-party services, legal requirements, platform policies, or privacy practices.

Updated versions will be published together with an updated revision date.

Users are encouraged to review this Privacy Policy periodically.
