Privacy Policy
Effective September 8, 2026
Lany Business is a Business English learning application operated by LangCo and developed with NeosIA support. This policy explains how information is handled when you use the app.
1. Information we collect
- Account information, including your name, email address, verification status and internal user identifier.
- Learning information, including assessment results, CEFR placement, lesson progress, XP, streaks, practice limits and recommended review topics.
- Conversation and exercise information, including transcripts, answers, corrections, accuracy and session history.
- Content reports, including the reported AI response, recent conversation context, your user identifier, the related session identifier when available and the report time.
- Voice recordings submitted for speaking or conversation practice. Audio is transmitted for speech processing; Lany stores learning results and transcripts rather than a permanent raw-audio library.
- Subscription, enterprise-access and rewarded-ad status needed to unlock features.
- Technical diagnostics such as app version, platform, device information and crash reports.
2. How we use information
We use information to authenticate users, verify email ownership, personalize difficulty, deliver lessons and AI-assisted practice, calculate progress, enforce free-use limits, automatically filter potentially harmful content, review reported AI responses, manage subscriptions and enterprise access, prevent abuse, provide support, and improve reliability.
3. Service providers
We use carefully selected providers to operate Lany Business. These may include Firebase and Google Cloud for authentication, data and diagnostics; OpenAI for AI, transcription and text-to-speech features; RevenueCat and the Apple App Store or Google Play for subscriptions; Google AdMob and its consent platform for rewarded advertising; Expo/EAS for app builds and updates; and Hostinger for transactional email. Each provider processes information under its own terms and privacy commitments.
4. Advertising and consent
Free users may choose to watch rewarded advertisements to unlock additional curriculum practices. Where required, the app displays Google's consent form before requesting ads. On iOS, Lany also requests Apple's App Tracking Transparency permission before allowing the advertising SDK to access a device advertising identifier for personalized advertising and measurement. If permission is declined, Lany remains usable and advertising may be limited or non-personalized. Advertising privacy choices can be reviewed from Settings. Lany does not require an ad for the 30 weekly Conversation Practice exchanges.
5. Sharing and sale of data
We do not sell personal information. We share information only with service providers needed to operate the app, when a user asks us to share it, or when required to protect users, enforce our terms, or comply with law.
6. Data retention and deletion
Account and learning information is retained while an account is active and as reasonably necessary for security, support, legal and operational purposes. Users can permanently delete their account from Settings. This removes the Firebase account, profile and conversation history from active systems; limited backup or transaction records may remain when required by law or platform obligations.
7. Security
We use authenticated access, server-side authorization, encrypted network connections and restricted secrets. No security method is perfect, so users should keep their passwords private and contact us about suspected misuse.
8. Your choices and rights
You may access and update account information in the app, review advertising choices, request support, sign out, or delete your account. Depending on your location, you may also request access, correction, restriction or a copy of your personal information.
9. Children
Lany Business is designed for adults and is not intended for anyone under 18.
10. Changes and contact
We may update this policy as the service evolves. Material changes will be communicated through the app, email or this page. Questions and privacy requests may be sent to lany@langco.com.mx.
