Kolingo has no sign-up. We never ask for your name, email, phone number or photos.

• Random IDs: a random ID created on your device when you first open the app, and an anonymous Firebase user ID. Neither contains anything about who you are.
• Learning activity: how you answer each exercise (right or wrong, what you typed in dictation, hints used, how many times you replayed the audio, time taken), and when you finish a session or a unit.
• Subscription status: whether you have Kolingo Pro, which plan you bought and from which store, and when the app last checked it with the store.

We do not collect your location, contacts, microphone, camera or advertising ID. Payment details such as card numbers are handled by the App Store or Google Play and never reach us.

• To schedule your reviews and show your progress in the app.
• To see whether the lessons actually help people hear Korean, and to improve them.
• To keep Kolingo Pro working, including after you reinstall the app.

No ads, no tracking across other apps or websites, and no selling or sharing of your data with anyone for their own use.

Your learning activity is saved on your device first, then copied to our server (Google Firebase) under the anonymous IDs above. It is not linked to your identity.

Your Apple or Google account is never shared with us.

• Google Firebase (Google LLC): anonymous sign-in, storing learning activity, and delivering lesson audio. Its servers may be outside your country, including the United States.
• App Store (Apple) and Google Play (Google): payments and subscriptions, under their own privacy policies.

Kolingo is meant for people aged 16 and over. We do not knowingly collect data from children under 16.

We keep learning activity only as long as we need it to improve Kolingo, and then delete it.

• Deleting the app removes everything stored on your device and stops all collection.
• To have your records deleted from our server, or to ask what we hold, email comely1515@gmail.com. Because we don't know who you are, we will ask a few questions (for example, roughly when you installed the app and on which device) to find your records.
• Subscriptions are cancelled in the App Store or Google Play, not in the app.

If this policy changes, we will update this page and the date above, and tell you in the app for important changes.
