Terms of Service

These Terms of Service govern the Linguru mobile application ("the App") operated by Erhal Olcel (individual developer, İstanbul, Türkiye). By downloading the App or creating an account, you accept these terms.

The App is for users aged 16 and above. You must be at least 16 years old to create an account. You are responsible for the accuracy of the information you provide.

Students under 18 do not use the App themselves. The account is created and used by a parent or legal guardian on their behalf, and that adult is responsible for everything done through the account.

Each user may have only one account. You are responsible for keeping your password confidential and for all actions performed through your account.

The App offers:

• Daily English lesson content (Topics)
• Interactive games including Fill in the Blank, Flashcards and Word Hunt
• The LinguruAI assistant — answers language learning questions only, subject to a daily message limit
• Daily tips, surveys, and announcements
• Cambridge-based placement test
• 28-Day Speaking Marathon and audio recording evaluation

Services may be improved, modified, or discontinued from time to time. Material changes are notified in advance.

By using the App you agree not to:

• Submit unlawful, defamatory, or harassing content
• Reverse engineer the App's source code or use automated bots/scripts
• Misuse another user's account, information, or identity
• Submit audio containing individuals who have not consented
• Infringe copyright, trademark, or any other intellectual property right
• Spam, launch DoS/DDoS attacks, or harm the service

Accounts violating these rules may be suspended or terminated without prior notice.

The App is free. There are no in-app purchases, subscriptions or paid features; every feature is available to every user. Should a paid service be introduced in the future, these terms will be updated beforehand and users will be notified.

The App's source code, design, logo, and content (lesson text, tips, game designs, etc.) are protected by copyright and operated by Erhal Olcel. They may not be copied, distributed, or modified for non-personal purposes.

Content you submit (audio recordings, messages, survey responses) remains your intellectual property. However, you grant us the right to process this content for evaluation, improvement, and legal compliance purposes.

Content and technical infrastructure are updated periodically. Scheduled maintenance is announced in advance. We are not directly liable for damages arising from unplanned outages, but access is restored as quickly as possible.

The App is provided "as-is". No express or implied warranty is given that English learning progress will be achieved — outcomes vary by individual.

Erhal Olcel is not liable for indirect, incidental, or special damages arising from App use; data loss; loss of profit; or reputational harm. Total liability for direct damages is limited to the total payments made by the affected user in the preceding 12 months.

These terms are governed by the laws of the Republic of Türkiye. Disputes shall be resolved before the Istanbul Central (Çağlayan) Courts and Enforcement Offices. For consumer users, Law No. 6502 on Consumer Protection provisions are reserved — including access to consumer arbitration committees and consumer courts.

These terms may change. Material changes are announced in-app; continued use constitutes acceptance of the updated terms.
