This Privacy Policy explains how LANGOOO collects, uses, protects, and deletes information when you use Langooo.
Effective date: June 4, 2026
When you sign in with Google, we may collect basic Google account profile information such as your name, email address, and profile image. We also collect learning-related data you create in Langooo, including vocabulary progress, saved words, language preferences, lesson history, review activity, and learning statistics.
We use your data to operate Langooo, customize translation context, calculate spaced repetition review timing, sync your progress across devices, display learning statistics, manage account access, improve product quality, and provide support.
Payments for Langooo Pro are processed securely by Stripe. LANGOOO does not store full credit card numbers on its own servers. Stripe may process payment data according to its own security and privacy practices.
Langooo may use cookies, browser storage, and similar technologies to keep you signed in, save local guest data, remember preferences, support PWA functionality, measure usage, and keep the service secure.
We use reasonable technical and organizational safeguards to protect user information against unauthorized access, loss, misuse, and alteration. No online service can guarantee perfect security, but we work to keep Langooo data protected.
Users can clear local learning data from the app settings. You may also request account or data deletion by emailing support@langooo.app. We will process deletion requests as required by applicable law and may retain limited information where necessary for legal, security, fraud prevention, or accounting purposes.
