Using an existing account
Sign in with your existing Biyoloji Hikayesi account. Access to lessons, activity solutions and questions is determined by current account and subscription rights on the server. This app does not offer account registration or purchases. Some content requires an existing paid subscription.
Offline downloads
A topic's lesson, eligible images and accessible practice/past-exam questions are downloaded together. Free accounts receive the available preview. Updating a package online checks current access rights again.
Offline permission lasts up to seven days, or until the relevant subscription expires if earlier. When permission expires, connect to the internet and update the topic to continue according to your current rights.
Content and personal study
Offline packages include text, eligible images and published questions. Videos are not downloaded. Images that cannot be packaged are identified in the content. Offline question selections remain on the device.
Use the material for education and personal study. Republishing or distributing content for others requires the publisher's permission.
Account changes and device clearing
Changing accounts clears the previous account's downloaded packages. Clearing the local account also removes local question selections. This does not delete the server account or subscription records. To request server account deletion, use the account and data deletion page.
Support
Report content or app issues by email or the in-app support form. The form requires internet access. The current app interface and educational content are in Turkish; these information pages are also available in English.
