Privacy Policy
Effective date: April 1, 2026
In short: Migo is built for young children. We do not show ads or use advertising identifiers. The App stores a child's profile and progress locally on the device, and we use Firebase for analytics, crash reporting, and content delivery. Optional parent sign-in uses Sign in with Apple and Firebase Authentication.
1. Who We Are
Migo Language Playground ("Migo", "we", "us", or "our") is a mobile application that helps young children learn languages through interactive games. This Privacy Policy explains how we handle information when you use the Migo app (the "App").
2. Our Commitment to Children's Privacy
Migo is designed for children under 13 and is intended to be set up by a parent or legal guardian. We comply with:
- COPPA (Children's Online Privacy Protection Act) — United States
- GDPR (General Data Protection Regulation) — European Union
- Apple's App Store Guidelines for kids' apps
3. Information We Collect
3a. Information We Do Not Collect for Advertising or Cross-App Tracking
We do not use the App to collect any of the following for advertising or cross-app tracking purposes:
- Advertising identifiers
- Persistent identifiers used to track a child across apps or websites
- Photos, videos, or audio recordings
- Precise geolocation
- Contact information from children through the in-app child experience
3b. Device-Local Data
The App stores learning progress, settings, and preferences locally on the device. This can include a child's first name, selected gender, selected languages, puzzle preferences, game scores, and parental controls such as a parental PIN. Based on the current version of the App, this data is stored locally on the device and is not synced to our servers as part of the child experience.
3c. Analytics and Crash Reporting
We use Firebase Analytics and Firebase Crashlytics to understand how the App is used, measure feature usage, and diagnose crashes and technical issues. Analytics events may include app interactions such as which screen was opened, which category or language was selected, puzzle difficulty, gameplay outcomes, and onboarding completion steps. We do not use advertising identifiers, and we do not use these services to track children across third-party apps or websites.
3d. Parent Account Information
If a parent chooses to use optional Sign in with Apple, we process parent account information through Apple and Firebase Authentication. This may include a Firebase user ID and the parent's Apple-provided email address.
3e. Contact Form
If a parent contacts us through our support page, we collect the information they voluntarily provide (name, email, message). This information is used only to respond to the inquiry and is never associated with a child's activity.
4. How We Use Information
We use the limited information described above to:
- Provide the App's educational features and save progress on the device
- Improve the App and understand which features are being used
- Fix crashes and technical issues
- Support optional parent sign-in features
- Respond to parent support requests
5. Information Sharing
We do not sell or rent personal information. We do not display advertisements. We share data only with service providers that help us operate the App:
- Firebase (Google) — for analytics, crash reporting, authentication, and content delivery, governed by Firebase's privacy policy
- Apple — for App Store distribution and optional Sign in with Apple
6. Data Retention
Device-local data persists until it is deleted from the device or the App is uninstalled. Parent sign-in data is retained according to Apple and Firebase Authentication account settings and deletion workflows. Contact form submissions are retained only as long as needed to resolve the inquiry. Analytics and crash reporting data are retained according to Firebase's retention settings.
7. Parental Rights
As a parent or guardian, you have the right to:
- Review device-local data associated with your child's use of the App
- Delete your child's device-local data by uninstalling the App or clearing the App's local data
- Delete a parent account created through Sign in with Apple and Firebase Authentication
- Contact us to request deletion of any support inquiry data
- Withdraw consent for your child's use of the App at any time
8. Security
We use industry-standard security measures to protect the limited data we handle. Device-local data is protected by the device's built-in security features. Data handled by our service providers is subject to their security controls and policies.
9. International Users
If you are located in the European Economic Area (EEA) or United Kingdom, you have additional rights under GDPR, including the right to access, rectify, or erase personal data. To exercise these rights, please contact us.
10. Changes to This Policy
We may update this Privacy Policy from time to time. The updated version will be posted on this page with a new effective date. We encourage you to review this page periodically.
