RTS Plus

Terms of Purchase, Use & Cancellation

Version 23.10.2026 · These terms apply to RTS Plus access bought on royalturkish.com/practice and to RTS Plus subscriptions bought in the RTS Plus app. Language courses, accommodation and other school services of Royal Turkish Schools are not covered by these terms; they are governed by the school's Terms & Conditions and Refund Policy.

1. Who we are

RTS Plus (the website lessons and the RTS Plus app) is operated and sold by Royal Daniel Özer ("we"), a sole proprietorship registered in the commercial register of the canton of Zurich, Switzerland, company number CHE-221.627.654, Dübendorfstrasse 4, 8051 Zürich, Switzerland; owner: Daniel Özer. You buy RTS Plus from us, not from Royal Turkish Schools. Contact: [email protected], +90 212 244 27 62.

The course content — lessons, texts, audio recordings and the teaching method — is created by RTS Royal Schools Dil Okulları Eğitim Danışmanlık Turizm Ticaret Limited Şirketi ("Royal Turkish Schools"), a language school licensed by the Turkish Ministry of National Education in Istanbul, Türkiye, and is used in RTS Plus under licence.

2. What RTS Plus includes

RTS Plus unlocks the full PUSULA lesson path — currently 252 Turkish lessons in 36 units at levels A1, A2 and B1 — with the audio material, the quizzes, speaking practice, progress tracking and a digital RTS Plus Certificate of Completion for each level you complete. Unit 1 of each level (A1, A2 and B1; 21 lessons in total), conversation practice with our AI teacher Eda within daily fair-use limits, and messaging remain free of charge without RTS Plus. We add new lessons and languages over time; paid access covers everything available in the app during your access period, in all languages we publish. Live lessons, classroom courses and any service delivered by a human teacher are not part of RTS Plus and are sold separately.

3. Price and payment

4. Ending your access and cancelling store subscriptions

5. Right of withdrawal and refunds

If you are a consumer in the European Union, the United Kingdom or Türkiye you have a statutory right to withdraw from a distance contract within 14 days. Because RTS Plus gives immediate access to digital content, before paying on our website you tick a box confirming that access starts immediately and that you lose your 14-day right of withdrawal once the lessons are unlocked. Where the law allows, the right of withdrawal therefore ends when the paid lessons are made available to you.

Beyond the statutory rules we apply a simple goodwill rule: if you have completed no more than two paid lessons, write to us within 14 days of payment and we refund the full amount, no questions asked. Refunds are paid to the original payment method within 14 days. Purchases made in the App Store or Google Play must be refunded through Apple or Google, as we have no access to those payments.

6. Your account

You need an account (e-mail address with password or passkey, or Sign in with Apple) so that we can save your progress and purchases across devices; a purchase in the app is linked to the account you are signed in to. One account is for one learner; please do not share your login. You can delete your account at any time in the app (Profile → Delete account) or by writing to [email protected]. Deletion immediately removes your account, learning progress, Eda conversations, profile photo, the messages and files you sent and your device notification tokens, and cancels any certificate issued to you; records we must keep for accounting purposes are kept as required by law. Deleting your account does not cancel an App Store or Google Play subscription — cancel it in your store settings as described in section 4.

7. Our AI teacher

Eda is an artificial-intelligence tutor, not a human teacher, and this is shown in the app. Eda can occasionally make mistakes; nothing Eda says is legal, medical, financial or immigration advice. Your conversations are stored so that Eda remembers your level and progress, and may be reviewed in anonymised form to improve the service. Eda's answers are generated by an AI model provided by Anthropic. Please do not enter passwords, payment details or other sensitive personal data in the chat. If an answer from Eda seems wrong or inappropriate, report it in the app or write to us.

8. Messaging

The app lets you write to our school team and, if you switch it on, to other learners you add yourself by QR code or e-mail. Messaging with other learners is only for users aged 18 and over who accept the community rules shown in the app: be kind and respectful; no harassment, hate, sexual content, advertising, scams or requests for money; and no sharing of phone numbers, e-mail addresses or social-media accounts. Messages and shared photos are checked automatically by an AI moderation system before they are delivered, and messages that break the rules are not sent. You can block anyone and report a conversation in the app; we review every report within 24 hours and may restrict or close accounts that break the rules. Messages are stored on our servers so that they are available on all your devices; they are not end-to-end encrypted. Writing to the school does not create a contract for a course — courses are booked separately.

9. Certificate

Passing all lessons of a level (A1, A2 or B1) and providing your full name (first and last name) produces the digital RTS Plus Certificate of Completion for that level, issued by Royal Turkish Schools and verifiable online. It is a self-study app certificate: it records your progress in the app. It is not an official course certificate (it is not a Kurs Bitirme Belgesi issued under the Turkish Ministry of National Education, MEB), not an examination result and not an officially recognised language certificate.

10. Age

RTS Plus is intended for learners aged 16 and over. Learners between 13 and 16 may use the lessons with the consent of a parent or guardian, who accepts these terms on their behalf. Messaging with other learners is available only from age 18.

11. Content, availability and changes

We may add, change or retire lessons and features. If we permanently stop the service during a paid period, we refund the unused part of your payment. We do our best to keep the service available but cannot guarantee uninterrupted access; short maintenance interruptions are possible.

12. Intellectual property

All lessons, texts, audio recordings and course materials belong to Royal Turkish Schools and are used by us under licence; the RTS Plus app and software belong to us. You may use the content for your own learning. Copying, redistributing, publishing or using them to train other systems is not permitted.

13. Data protection

For RTS Plus, Royal Daniel Özer (Zurich) is the controller of your personal data. We process it under the Swiss Federal Act on Data Protection (FADP) and, where applicable, the EU General Data Protection Regulation (GDPR). We use service providers to run RTS Plus — Google Firebase / Google Cloud (hosting, database, sign-in), Anthropic (AI teacher Eda, message help and moderation), RevenueCat (managing App Store and Google Play subscriptions), Apple and Google (store purchases and push notifications) and our payment providers for website purchases — who process data only on our instructions. What we store, why, and your rights are described in the Privacy Policy. Data-protection requests: [email protected].

14. Complaints and applicable law

Write to [email protected] and we answer within five working days. These terms are governed by Swiss law. If you are a consumer, you keep the protection of the mandatory consumer rules of your country of residence and may bring a claim before the courts of that country; otherwise the courts of Zurich, Switzerland, have jurisdiction. Consumers in the EU can also use the European Commission's online dispute resolution information.
