Privacy Policy

Last Updated: November 18, 2025

Language Island ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our mobile application and services.

1. Information We Collect

1.1 Information You Provide

Account Information: When you create an account, we collect your email address, username, and password.
Profile Information: Optional information such as your name, profile picture, and preferred languages.
Learning Data: Information about your language learning progress, including sentences studied, confidence levels, and practice history.
User Content: Custom sentences you create and any feedback you provide.

1.2 Automatically Collected Information

Usage Data: Information about how you interact with the app, including features used, time spent, and navigation patterns.
Device Information: Device type, operating system, unique device identifiers, and mobile network information.
Performance Data: App crashes, error logs, and performance metrics to improve our services.
Diagnostics & Telemetry (optional): If you opt in from the Language Island app, we collect anonymized session diagnostics through our analytics service providers. These logs may capture touch interactions, navigation events, screen names, device model, OS version, and basic network telemetry. Text inputs, images, and sandboxed or native views are automatically masked before anything is sent, and you can enable or disable diagnostics at any time in Settings → Diagnostics & Telemetry.

2. How We Use Your Information

We use the collected information for the following purposes:

Provide Services: To deliver, maintain, and improve Language Island's features and functionality.
Personalization: To customize your learning experience based on your progress and preferences.
Spaced Repetition: To optimize review schedules and show you sentences at the most effective times.
Communication: To send you updates, notifications, and respond to your inquiries.
Analytics: To understand usage patterns and improve our app's performance and features.
Diagnostics Telemetry: To debug crashes, measure feature adoption, and prioritize new functionality. Diagnostics data is never sold or used for advertising and is linked only to an internal identifier—never to your name or email.
Security: To protect against fraud, abuse, and security threats.

2.1 Legal Bases for Processing (GDPR and Similar Laws)

Where applicable laws (like the GDPR) require a legal basis for processing, we rely on the following:

Performance of a Contract or Legitimate Interests: To provide core features, personalize your experience, maintain the Service, and ensure security.
Consent: Diagnostics telemetry is collected only if you opt in (GDPR Art. 6(1)(a)). If you decline or later withdraw consent in the app, telemetry collection stops immediately.

3. How We Share Your Information

We do not sell your personal information. We may share your information in the following circumstances:

3.1 Service Providers (Third-Party Processors)

We partner with carefully vetted service providers who help us operate the app and deliver optional features such as diagnostics telemetry. These processors may change over time, but each is bound by strict confidentiality and data-protection obligations.

Cloud hosting and storage services
Diagnostics and analytics platforms (optional session replay and telemetry hosting)
Customer support tools
Payment processors (for premium features)

When diagnostics telemetry is enabled, our analytics providers process anonymized session data on our behalf solely to help us improve the Service.

3.2 Legal Requirements

We may disclose your information if required by law or in response to valid legal requests by public authorities.

3.3 Business Transfers

If Language Island is involved in a merger, acquisition, or sale of assets, your information may be transferred as part of that transaction.

4. Data Retention

We retain your personal information for as long as your account is active or as needed to provide you services. You can request deletion of your account at any time, and we will delete your personal information within 30 days, except where we need to retain it for legal obligations.

Diagnostics telemetry replays stored by our analytics service providers are retained for up to 30 days (their default retention window) and are then automatically deleted. We may keep aggregated, non-identifiable statistics derived from telemetry for longer to understand trends without storing the underlying recordings.

5. Data Security

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

Encryption of data in transit and at rest
Regular security audits and testing
Access controls and authentication requirements
Secure data centers and infrastructure

However, no method of transmission over the Internet or electronic storage is 100% secure, and we cannot guarantee absolute security.

6. Your Privacy Rights

Depending on your location, you may have the following rights:

Access: Request a copy of your personal information.
Correction: Request correction of inaccurate information.
Deletion: Request deletion of your personal information.
Portability: Request a copy of your data in a structured format.
Objection: Object to certain processing of your information.
Withdraw Consent: Withdraw your consent where we rely on it.

To exercise these rights, please contact us at [email protected].

You can also manage your privacy choices directly in the Language Island mobile app. Diagnostics & Telemetry can be toggled on or off at any time, and you can contact [email protected] to request a global opt-out. If you reinstall the app or sign in on a new device, we will ask for your preference again before telemetry resumes.

7. Children's Privacy

Language Island is not intended for children under 13 years of age. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided us with personal information, please contact us, and we will delete it.

8. International Data Transfers

Your information may be transferred to and processed in countries other than your country of residence. We ensure that appropriate safeguards are in place to protect your information in accordance with this Privacy Policy.

9. Third-Party Links

Our app may contain links to third-party websites or services. We are not responsible for the privacy practices of these third parties. We encourage you to review their privacy policies.

10. Changes to This Privacy Policy

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

If you have questions, concerns, or requests regarding this Privacy Policy or our privacy practices, please reach out through our contact form.
