Questions, bug reports and ideas: sezerta@gmail.com. We usually reply within 2 business days.

How do I delete my account and data?

Open the account section in the App and choose Delete account. This removes your authentication record and all server data (profile, progress, quiz results, XP and badges, token wallet and ledger, AI usage metadata). If you cannot open the App, e-mail sezerta@gmail.com with the subject "Account deletion" from your Apple e-mail or stating your display name; we finish within 30 days at the latest. Local data (lessons, plans, chat history) is removed when you uninstall the App.

Note: unused tokens in a deleted account cannot be recovered. Parents and guardians can request deletion for a child's account the same way.

Is the app free? Are there ads?

Downloading is free. Math practice, flashcards, the planner and the focus timer work without an account and offline. Basic AI (the on-device AI coach) is free. Advanced AI (photo help, harder questions, AI lessons and quizzes) needs Sign in with Apple and a token pack. There are no forced ads; you can optionally watch a rewarded, non-personalized ad for an extra quiz attempt or 3 more Basic AI messages.

Why don't I see Basic AI?

Basic AI uses Apple Intelligence, which runs only on supported devices (iPhone 15 Pro or later) with iOS 26. Check that your device is supported, is updated to iOS 26, and that Apple Intelligence is turned on in Settings > Apple Intelligence & Siri. If your device is not supported, Advanced AI still works with a token pack.

What is the difference between Basic and Advanced AI?

Basic AI: free; runs on your device with Apple Intelligence, needs no internet or account, and your questions never leave the device. You get 3 messages, then an optional short rewarded ad unlocks 3 more (repeat as often as you like). No photo solving; as a small model it can make mistakes. Advanced AI: the cloud AI coach, with a token pack and Sign in with Apple. Photo solving, harder questions, AI lessons and AI quizzes are only here.

What are tokens and how do they work?

Tokens fuel AI answers. Each answer deducts 5 times the number of tokens the AI provider used. A typical question and answer is about 5,000 tokens; photos and long chats use more. Your balance is always shown in the AI coach screen.

Which packs exist?

Starter 100,000 tokens, Standard 300,000 tokens, Large 1,000,000 tokens. Prices are shown in the App. Packs are one-time purchases, not subscriptions, and tokens do not expire.

Can I get a refund?

Apple processes payments, so refunds go through Apple: reportaproblem.apple.com. Refunded tokens are removed from the wallet.

I bought tokens but they were not credited.

Close and reopen the App; pending purchases are retried automatically. If that does not help, write to us with the transaction ID from Apple's receipt e-mail.

Are my chats stored?

No chat content is stored on our server. Basic AI chats never leave your device. For Advanced AI answers, your question is sent to the AI provider (Anthropic) and returned to you; only token counts, time and mode are logged. Chat history stays on your device. See the privacy policy.

Why do I need Sign in with Apple?

Only for Advanced AI and syncing progress. Basic AI needs no account. It is the only method and no password is stored. You can use "Hide My Email".

Which language is the content in?

The app interface comes in 34 languages and follows your device language. Lesson and quiz content is in English (the Turkish edition follows the Turkish curriculum in Turkish).

What if the AI is wrong?

AI answers can be wrong. Rely on your textbook and teacher for anything important.
