Privacy Policy
Last updated: November 11, 2026
Ugiwise ("the app") is made by Uğur Can Usta ("I", "me"). This policy explains what information the app uses, where it goes and how you can delete it.
The short version
You can use Ugiwise without an account. Without one, your lesson progress stays on your device. On iPhone you can choose to sign in with Apple to save your progress to an account and get it back later, including on another iPhone. The app shows no ads and contains no advertising software. It sends anonymous usage data, such as which lessons are started and finished. Payments are handled by Apple or Google.
Information stored on your device
The app saves your course progress, settings and reminder preferences in the app's own storage on your device. If you don't sign in, this information is not sent to me or to anyone else, apart from the anonymous usage events described under Usage analytics. Deleting the app deletes it. Your device's own backup (for example iCloud Backup) may include it, under Apple's or Google's terms.
Optional account: Sign in with Apple (iPhone)
Signing in is optional, and every lesson works without it. If you choose Sign in with Apple, the app creates an account for you on a server I run with Supabase (Supabase, Inc.), in the United States. Apple gives the app an identifier for your Apple ID; the app does not ask Apple for your name or email address.
While you are signed in, the app saves to your account:
- your learning progress: the lessons you finished, your XP, your answers and attempts in lessons, bookmarks, the courses you started and the choices you made in the app (such as your daily goal);
- your player name, if you entered one;
- the previous saved copy of your progress, and when each copy was saved.
This is used only to keep your progress and give it back to you when you sign in. I do not sell it, use it for advertising, or combine it with information from other companies. Your sign-in is kept in your iPhone's Keychain, on that device only.
To run and protect the service, Supabase keeps technical logs of requests to the server, such as IP addresses and times, for up to 7 days. See Supabase's privacy policy and Apple's.
Signing out and deleting your account
When you sign out, the app first saves your progress to your account, then removes the account's progress from the phone. There is one exception: when the app cannot settle which progress to keep (for example, your account and this iPhone hold different progress, or a switch between them could not be confirmed), you can sign out without saving. This option signs you out and keeps this iPhone's progress; it does not change the result of a server request that was still pending.
You can delete your account in the app: Profile → Account → Delete account. This deletes your account and the progress saved to it from the server and withdraws the app's Sign in with Apple access. To confirm that the deletion finished, the server keeps a short record of the request: a random request number, your account's internal number, its status and times, for 30 days. Backup copies of the server's database are kept for up to 7 days, so deleted progress is gone from them within that time. Deleting your account does not cancel a subscription; that is managed in your Apple ID settings.
You can also ask me to delete your account, or for a copy of the progress saved to it, at support@ugiwise.com.
Notifications
If you turn on daily reminders, the app schedules them on your device. The reminders and their times stay on your device; only the fact that you turned reminders on or off is sent, as an anonymous usage event (see Usage analytics).
Purchases
Ugiwise Pro is sold through the Apple App Store and Google Play. Payment is handled entirely by Apple or Google; I never see your payment details.
To check whether you have an active purchase, the app uses RevenueCat (RevenueCat, Inc.). RevenueCat receives an anonymous app user ID, your purchase and subscription history, and basic technical information such as the app version, device model and country. This is used to unlock Pro, restore your purchases and show me purchase statistics (for example, how many people subscribed). It is not connected to your Ugiwise account. See RevenueCat's privacy policy.
Usage analytics
To see which lessons work and where learners stop, the app sends anonymous usage events to TelemetryDeck (Germany). The events are:
- the start of a session of using the app, and the first time the app is opened after it is installed;
- finishing the first-run setup, and the course chosen;
- starting and finishing a lesson: which course, unit and lesson, and whether it was the first time;
- leaving a lesson before the end: which course, unit and lesson, how far through it you were (the step number), and whether you closed the lesson or switched to another app;
- opening and closing the Ugiwise Pro screen, and where it was opened from;
- a completed or restored purchase, with the product bought and whether it started a free trial (not the price);
- turning daily reminders on or off;
- the app asking the store to show its rating window.
Each event also carries basic technical information such as the app version, device model, system version, language and region, screen size and accessibility settings like text size. To count how many devices use the app, an identifier is made from your device and hashed on the device before it is sent; your name, email, Apple ID, Ugiwise account and RevenueCat ID are never sent, and neither are your answers, anything you type or your payment details.
This information is not used for advertising or to track you, and it is not combined with other data, including your Ugiwise account. See TelemetryDeck's privacy policy.
Advertising
The app shows no ads and contains no advertising software.
Children
Ugiwise is not directed at children under 13, and I do not knowingly collect information from them.
