Privacy Policy

We collect three categories of information. (1) What you give us: phone number or email at sign-up, display name, avatar, learning goals, and self-reported English level. If you sign in via Google / Apple / WeChat, we receive basic profile data from those platforms. (2) What we generate as you use the app: watch history, favorites, pronunciation recordings, pronunciation feedback results, dictionary lookups, session duration, streaks, device model, OS version, app version, IP address (for regional routing), and crash logs. (3) What we only collect with your permission: microphone audio, photo library, and notifications.

We use collected information to: · Run and improve core features (recommendations, subtitles, pronunciation feedback) · Personalize content and difficulty · Protect accounts, prevent abuse and cheating · Send product updates and learning reminders (you can turn these off anytime) · Comply with the law and resolve disputes · Conduct research, only on anonymized and aggregated data We do not sell your personal data to third parties for advertising.

We share information only in these cases: · Service providers: hosting (AWS / Aliyun), CDN, push notifications, customer support. All bound by data processing agreements with equivalent protection standards. · Legal requests: when required by court orders, law enforcement, or other lawful authority. · Business changes: in case of merger or acquisition, we'll notify you 30 days in advance and let you delete your account. · With your explicit consent: e.g., if you authorize a third-party learning community to read your progress.

Data from mainland China users is stored on servers inside mainland China; data from other regions is stored in that region or the nearest compliant overseas server. We use TLS 1.3 in transit and AES-256 at rest for sensitive fields (passwords, raw pronunciation data). After account deletion, related data is irrecoverably wiped within 30 days, except where the law requires us to keep it.

The LingoFly app doesn't use browser cookies, but does use local storage for sign-in tokens, video caches, and subtitles. Our website may use strictly necessary cookies (to keep you signed in) and anonymous analytics cookies (to count visits). You can disable cookies in your browser settings, but some features may break.

LingoFly is intended for users aged 16 and over. Children under 13 must not register or provide personal information. If we learn an account belongs to a child under 13, we'll delete it promptly. Parents who suspect unauthorized use by a child can request deletion via contact@glosightai.com.

You have the following rights over your data: · Access: download a copy in "Me → Privacy → My Data." · Correction: update your profile anytime. · Deletion: tap "Delete Account" in-app; your data will be erased within 30 days. · Opt out of personalization: toggle off "Personalized recommendations" in settings. · Withdraw consent: revoking permissions (mic, notifications) doesn't affect data already processed. · Complain: if you're unhappy with how we handle your data, you can complain to your local data protection authority.

We use industry-standard security measures: encrypted transit, regular security audits, least-privilege access, and two-factor authentication for admins. That said, no system is 100% safe — please keep your password secure too. In the event of a breach, we'll notify regulators and affected users within 72 hours.

If you use LingoFly outside mainland China, your data may be transferred to the country where our servers are located. We make sure the recipient provides an equivalent level of protection and, where required, sign Standard Contractual Clauses (SCCs).

We may update this policy from time to time. For material changes (e.g., new uses of data), we'll notify you in a timely manner via in-app banner, push, or email. Continuing to use LingoFly means you accept the updated policy; if you don't, you can delete your account.

For any questions, complaints, or requests about this policy: · Email: contact@glosightai.com · In-app: Me → Help & Feedback → Privacy questions We'll respond within 15 working days.
