bilby1. Service and age group
Bilby: YKS TYT AYT is an education app offering topic cards, flashcards, mini quizzes and training activities for the available TYT and AYT subjects. These terms apply to the Android app with package name com.sinavhazirlik.bilby and the Bilby website.
Bilby is intended for users aged 13 and over. If you are a minor, you must obtain any required permission from a parent or legal guardian to use the service and make purchases. You must be authorised to use the payment account.
Bilby is an independent study tool, not an official app of ÖSYM or MEB. Content and results in the app do not constitute an official exam score or guarantee success or placement. Check the relevant institutions’ resources for official exam scope and announcements.
2. Use and content
You may use the app for personal learning. You must not copy content in bulk, republish it or distribute it commercially without permission. You must not disrupt the security of the service or other users’ access, or attempt to bypass subscription checks.
Available subjects and features may vary by version. Bilby does not promise complete coverage of every exam topic or subject. If you notice a content error, you can send the screen or topic details to our support address.
3. Premium subscriptions and pricing
The app is free to download. A premium subscription unlocks the features described on the purchase screen, such as unlimited lives, while the subscription is active. Before purchasing, check the included benefits, subscription period and total price.
- Weekly premium — TRY 89.99Charged for each one-week subscription period.
- Monthly premium — TRY 219.99Charged for each one-month subscription period.
- New subscriber offer — TRY 179.99 per month for the first three monthsFor eligible new subscribers, each of the first three monthly periods costs TRY 179.99. The subscription then renews at TRY 219.99 per month.
These are planned subscription prices for Türkiye. Product and offer availability depends on publication on Google Play, your region and your account’s eligibility. When sales become available, the purchase screen will show the applicable currency, total price including taxes, offer duration and subsequent renewal price. An offer does not apply unless it is presented on that screen.
TRY 179.99 is not a one-time total for three months. You pay TRY 179.99 in each of the first three months; the standard monthly price applies from the fourth month. This offer does not include a free trial.
Payments are processed through Google Play. RevenueCat is used to verify subscription access. Changes to prices or terms are applied through Google Play’s notification and, where required, consent processes.
4. Automatic renewal and cancellation
Weekly and monthly subscriptions automatically renew at the end of their respective periods unless cancelled. To avoid being charged for a new period, cancel your subscription in Google Play before the renewal date. You can view the renewal date and payment status in your Google Play account.
To cancel in Google Play, go to Profile → Payments & subscriptions → Subscriptions → Bilby → Cancel subscription. You can also use the Manage Google Play subscriptions page on the web.
Cancellation generally stops the next renewal; access continues until the end of the period you have paid for. Cancellation does not automatically refund previous payments. Uninstalling the app or clearing its data does not cancel your subscription. See Google Play subscription help for details.
5. Refunds, pending payments and restoration
Refund requests are assessed under Google Play’s applicable refund rules and relevant consumer law. You can submit a request through Google Play refund help or contact us. These terms do not remove your statutory consumer rights.
A pending or unverified payment may not unlock premium access until verification is complete. If you have an active subscription but cannot access it, make sure you are using the Google Play account used for the purchase and try the app’s Restore purchases option.
Restoring a purchase is not a new purchase. We do not promise automatic subscription transfers between different store accounts or platforms. If the problem continues, contact support without sharing card or banking details.
6. Learning progress and service access
Your learning progress is stored primarily on your device. Since there is no cloud synchronisation through a Bilby account, clearing app data, changing devices or being unable to restore a backup may result in lost progress. Android’s backup and transfer features depend on your device settings.
Some features, subscription verification and update checks require an internet connection. Maintenance, connectivity or provider issues may cause temporary interruptions. A newer app version may be required for security and compatibility.
See our Privacy Policy for details about data processing.
7. Rights, changes and support
Bilby’s branding, visuals and original content belong to their respective rights holders. Permission to use the app does not transfer ownership of that content. Your usage and consumer rights under applicable law remain reserved.
These terms may be updated as the service changes. The current text and date are published on this page. Changes affecting purchases or existing subscriptions follow the required notification and consent processes. Provisions that restrict mandatory legal rights are not treated as valid.
