Zebo

Last updated: 12 October 2026

Privacy Policy

Zebo works two ways: as a guest your progress stays on your phone, and if you sign in with your Apple account it is stored on our server. Below is exactly what is sent and what is not.

Guest mode

If you do not sign in, no account is created on the server: your lessons, streak, XP and word count stay on your phone alone. The app still downloads each lesson's illustration and Turkish audio from our server, without any account identifier attached.

If you sign in with Apple

When you press "Sign in with Apple", Apple gives us the following and we store it:

  • the user identifier Apple issues (a long, meaningless string);
  • your name, if you agree to share it;
  • your email address, if you share it. If you use Apple's Hide My Email, we only ever receive the private relay address and never see your real one.

From then on your study record is stored on the server: completed lessons, streak, XP and the number of words learned. That is what lets you carry on from another device.

No AI since version 1.0.3

Zebo 1.0.3 removed the AI tutor chat and the AI pronunciation tips. Nothing you type or say in Zebo goes to an AI service. Versions before 1.0.3 sent tutor messages, and the text of a speaking attempt, through our server to Microsoft Azure OpenAI; those requests are being switched off on our server as well, after which an old version's chat only asks you to update.

Pronunciation checking: your audio does not reach our server

In the speaking exercise, the app asks iOS to turn speech into text on the phone itself, and where the device supports that for Turkish, that is what happens. Some devices do not have the Turkish offline model — in that case iOS may send the audio to Apple's servers for recognition, which is governed by Apple's own privacy policy. Either way, the recording never goes to our server and we never store it. From version 1.0.3 the result is scored on the phone, so not even the recognised text is sent to us.

Images and audio files

The 287 lesson scenes and 1,929 Turkish audio recordings do not live inside the app; they sit on our server and are downloaded when needed. That is what keeps the app a few megabytes instead of several hundred. These are ordinary web requests, and technical data such as an IP address may remain briefly in the server log; we do not build profiles from it.

Zebo Pro (subscriptions)

Zebo Pro is sold through Apple's App Store. Apple takes the payment; we never see your card or any Apple payment details. To know who is a member we use RevenueCat, a subscription service: it receives the purchase record Apple issues (which plan, its price, the dates, renewal status), tied to a random identifier the app creates — or, if you are signed in, to your Zebo account, so that Pro follows you to a new phone. Cancel or change a subscription in your iPhone's App Store settings.

Notifications

Zebo asks iOS for permission to notify you once, after your first finished lesson. If you allow it:

  • The daily lesson reminder is scheduled on your phone. Nothing is sent to us for it.
  • Your phone's notification address (the push token Apple's notification service issues for Zebo), the app's language and the app's version are stored on our server — and, if you are signed in, which account the phone belongs to. We use it only for occasional notices about Zebo itself, such as a new version you need to install. Apple Push Notification service delivers them.

Switching off "Eslatmalar" (Reminders) in the Profile tab stops the reminder and deletes that address from our server. Deleting your account removes the link between the address and you.

What we do not do

  • No third-party analytics or advertising SDKs.
  • No advertising identifier (IDFA), and no tracking across apps or websites.
  • We do not sell your data and do not share it for advertising.
  • The microphone is switched on only during a speaking exercise, never in the background.

Who we work with

  • Apple - Sign in with Apple, notifications and the App Store.
  • RevenueCat - subscription records for Zebo Pro.
  • Microsoft Azure OpenAI - only for the AI features of versions before 1.0.3, until they are switched off.
  • Vercel - where our server runs.
  • Neon - the database holding study records.

Your rights

Account deletion is inside the app. At the bottom of the Profile tab there is "Hisobni o'chirish" (Delete account): you confirm once, and your account together with all of your progress, streak and achievements is removed from the server. You do not have to write to us to ask, and we keep no copy.

If you studied in guest mode there is no server-side record at all — deleting the app from your phone is enough.

If this policy changes, the date above changes with it and the current text stays on this page.
