Terms of Service

These Terms of Service (the "Terms") govern your access to and use of the Savantiva websites, applications, and related services (the "Services"). The Services are provided by Savantiva [Yazılım Ltd. Şti.], a limited liability company organised under the laws of the Republic of Türkiye ("Savantiva", "we", "us", or "our"). By creating an account or otherwise accessing or using the Services, you agree to be bound by these Terms and by our Privacy Policy. If you do not agree, do not use the Services.

1. Eligibility

You must be at least 18 years old to use the Services. The Services are intended solely for adults and are not directed to, and may not be used by, anyone under 18. By using the Services, you represent and warrant that you are at least 18 years old. We may ask you to confirm that you meet this age requirement, and we may suspend or terminate any account we learn belongs to a person under 18.

If you use the Services on behalf of another person or entity, you represent that you are authorised to accept these Terms on their behalf.

2. The Service

Savantiva is a language-learning platform designed to develop conversational ability through AI-powered dialogue and active production. We do not guarantee any particular linguistic outcome. We may modify, expand, suspend, or discontinue any part of the Services at any time; where we discontinue a material part of the Services, we will provide reasonable notice.

We may offer features in beta or experimental form, which we may label as such. Beta features are provided without any availability or accuracy commitment, and we may modify or withdraw them at any time.

3. Accounts

You must register an account to use the Services. You are responsible for maintaining the confidentiality of your credentials and for all activity that occurs under your account. You may hold only one account per person. Providing false information during registration, including as to your age, is grounds for suspension or termination. Notify us promptly at legal@savantiva.com if you believe your account has been compromised.

4. Acceptable Use

You agree not to:

• use the Services for any unlawful purpose or in violation of any applicable law or regulation;
• scrape, crawl, or extract data from the Services by automated means, or otherwise access the Services other than through the interfaces we provide;
• reverse engineer, decompile, disassemble, or attempt to derive the source code or underlying components of the Services, except to the extent this restriction is prohibited by applicable law;
• attempt to gain unauthorised access to, interfere with, disrupt, or overburden the Services, our systems, or other users' accounts;
• introduce viruses, malware, or other harmful code, or circumvent any security, rate-limiting, or protective measure;
• harass, impersonate, defame, or harm other users, or submit or distribute content that is unlawful, infringing, abusive, or otherwise objectionable;
• use the Services to develop, train, or support a competing product or service;
• use the Services if you are the target of applicable sanctions, or in violation of applicable export-control or sanctions laws.

You represent and warrant that you own or have secured all rights necessary to submit any content you provide through the Services, and that such content does not infringe or violate the intellectual property, privacy, or other rights of any third party.

We may determine, in our reasonable discretion, whether conduct violates these Terms, and we may investigate, remove or disable content, and suspend or terminate access in response, including without prior notice where necessary to protect the Services or others. Our systems may also automatically decline to answer, or withdraw, an individual message that appears to violate these Terms or applicable law.

5. Your Content

"Inputs" means the messages, prompts, and other content you submit to the Services. "Outputs" means the responses and other output the Services generate based on your Inputs. Inputs and Outputs are together "Content". "Content" does not include your payment information or content you have not actively submitted to the Services.

As between you and Savantiva, you retain ownership of your Inputs, and, to the extent permitted by applicable law, we assign to you our rights in the Outputs you receive. You are responsible for your Content and for ensuring it complies with these Terms and applicable law.

Because your Inputs are processed by third-party AI providers to generate responses, you should not submit sensitive personal information — such as data revealing health, religious or political beliefs, sexual orientation, or racial or ethnic origin — or other confidential information you do not wish to be processed in this way.

You grant Savantiva a worldwide, non-exclusive, royalty-free, and sublicensable licence to host, store, reproduce, modify, adapt, transmit, and display your Content, and to create derivative works from it, in each case as necessary to operate, provide, secure, and improve the Services. We do not use your Content to train or develop AI models; see Section 6 and our Privacy Policy.

Due to the nature of artificial intelligence, Outputs may not be unique, and other users may receive the same or similar Outputs in response to similar Inputs.

6. AI Features and Accuracy

To provide the Services, your Inputs are processed by AI model providers acting on our behalf. These providers are contractually restricted from using your Content to train their own models, except as necessary to provide the service to us. We do not use your Content to train or develop our own AI models, whether you use a free or paid plan; your Content is processed only to deliver and support the Services themselves.

AI accuracy. Outputs are generated by probabilistic models and may contain linguistic errors, cultural inaccuracies, outdated information, or other mistakes. The Services are intended for conversational practice. You should not rely on Outputs as authoritative instruction or as a substitute for professional advice, and you are responsible for evaluating Outputs before relying on them.

7. Community and Public Content

The Services include social features. Your profile and certain activity are public by default and may be visible to and searchable by other users, as described in our Privacy Policy. You are responsible for any content you make available to other users and should not include information in public fields that you do not wish to be visible. We are not responsible for how other users use it.

8. Subscriptions, Fees, and Payment

The Services are offered on a free tier and on paid subscription plans.

Web purchases. Payments made through our website are processed by Paddle — the Paddle entity applicable to your location under Paddle's Buyer Terms — which acts as the merchant of record and reseller for those transactions. Paddle, not Savantiva, is the seller of record and issues invoices and handles refunds for web purchases. Your payment details are handled directly by Paddle and are not stored on our servers.

Mobile purchases. Subscriptions purchased through the Apple App Store or Google Play are processed by Apple Inc. or Google LLC, respectively, under their own terms. Billing for in-app purchases is handled through the applicable app store under its terms. For Apple App Store purchases, Apple controls refunds and we are unable to issue them directly; please contact Apple. For Google Play purchases, you may request a refund through Google Play or by contacting us at legal@savantiva.com.

Renewal and cancellation. Paid subscriptions renew automatically for successive periods of the same length unless cancelled before the renewal date, through your account settings or, for mobile subscriptions, through your device's subscription-management settings. Except as required by applicable law or as expressly stated in these Terms, fees are non-refundable and we do not provide refunds or credits for partial or unused periods.

Taxes and price changes. You are responsible for all applicable taxes on your subscription. We may change subscription prices; we will give you at least 30 days' notice of a price change affecting your plan, and your continued use after the change takes effect constitutes acceptance of the new price.

Right of withdrawal (EU/EEA and Türkiye). If you are a consumer in the European Union or European Economic Area, or a consumer resident in Türkiye, you have a statutory right to withdraw from a paid subscription within 14 days without giving a reason — in the EU/EEA under the Consumer Rights Directive, and in Türkiye under Law No. 6502 on the Protection of Consumers and the Distance Contracts Regulation. If you ask us to begin providing the Services during the 14-day period, you expressly request early performance; you may still withdraw during that period, in which case you must pay a proportionate amount for the Services actually provided up to the moment you notify us that you withdraw, and you lose the right of withdrawal only once the Services have been fully performed. If you have not accessed any paid features, you are entitled to a full refund. You may withdraw by an unambiguous statement to legal@savantiva.com — for example, using the model withdrawal form available on request. This does not affect any mandatory withdrawal rights under the consumer-protection law of your country of residence.

8a. Presale

From time to time, before the Services are publicly available, we may offer access at a reduced early-access price (a "Presale"). The following terms apply to all Presale purchases and prevail over any conflicting provision of Section 8.

Billing and access. Presale purchases are charged immediately at the time of purchase. Access to the Services begins on the official product launch date, not at the time of purchase.

Pricing. A Presale purchase is a one-time payment that grants lifetime access to the Savantiva subscription at the tier you select. There is no recurring charge, renewal, or subscription created by a Presale purchase; the reduced Presale price is the full and only price you pay for that lifetime access.

Meaning of "lifetime". "Lifetime" means for as long as Savantiva continues to operate the Services. It is tied to the life of the Services, not to your lifespan, and is not a guarantee that the Services will be offered indefinitely. As described in Section 2, we may discontinue the Services at any time with reasonable notice; if we do, lifetime access ends at that point, subject to the refund rights below.

Your tier. The tier you select sets your ongoing usage allowance — the same allowance the equivalent recurring plan would provide. Higher tiers carry a higher allowance; every feature is included at every tier.

Fair use. Lifetime access is granted for personal, non-commercial use by a single individual and is subject to reasonable-use limits to protect the Services and other users. We may apply technical limits to prevent abuse, including automated, bulk, or commercial use, reselling access, or account sharing. Lifetime access is tied to your account and may not be sold, transferred, or assigned.

Presale only. Lifetime access is offered only during the Presale. After launch, the Savantiva subscription is available solely on a recurring basis, and one-time lifetime access will not be offered again.

Cancellation and refunds. Because access begins only at launch, you may request a full refund of your Presale purchase at any time before launch and before access has been granted. Once the Services have launched and access has been granted, refunds are governed by applicable consumer-protection law and the other provisions of these Terms. Refund requests may be submitted through your Paddle order receipt or to legal@savantiva.com. In addition, if we permanently discontinue the Services within 24 months after launch, we will refund lifetime Presale purchasers a pro-rata portion of the Presale price, calculated by reference to that 24-month period.

EU/EEA and Türkiye consumers. If you are a consumer in the EU or EEA, or a consumer resident in Türkiye, your statutory 14-day right of withdrawal applies in full to Presale purchases, since no paid features are accessible before launch. This statutory right is in addition to, and is not reduced by, the refund-until-launch right above.

Launch delay; non-launch. If launch is delayed beyond the originally stated window, we will notify Presale customers by email and offer the option to cancel for a full refund; failure to request a refund within 14 days of that notice constitutes acceptance of the delay. If the Services do not launch, all Presale customers will receive a full refund.

9. Intellectual Property

The Services, including their software, design, and content (other than your Content), and all intellectual property rights in them, are owned by Savantiva and its licensors and are protected by applicable law. Except for the limited right to use the Services in accordance with these Terms, no rights are granted to you. "Savantiva" and our logos are our trademarks; you may not use them without our prior written consent.

Feedback. If you provide us with suggestions or feedback about the Services, you grant us a perpetual, irrevocable, worldwide, royalty-free, and fully sublicensable licence to use it for any purpose without obligation or compensation to you.

10. Third-Party Services

The Services may interoperate with or link to third-party products and services that we do not control. We are not responsible for third-party services or content, and your use of them is at your own risk and subject to their own terms and policies.

11. Indemnification

To the fullest extent permitted by applicable law, you will indemnify, defend, and hold harmless Savantiva and its officers, employees, and agents from and against any claims, liabilities, damages, losses, and expenses (including reasonable legal fees) arising out of or related to: (a) your use of the Services in violation of these Terms; (b) your Content; or (c) your violation of any applicable law or the rights of any third party. We may assume exclusive control of the defence of any matter subject to indemnification, in which case you agree to cooperate with us.

If you are a consumer, you indemnify us under this Section only to the extent the relevant claim results from your intentional or negligent breach of these Terms or of applicable law, and not for any loss to the extent it results from our own act or omission; nothing in this Section limits or excludes your mandatory statutory rights.

12. Disclaimers

To the fullest extent permitted by applicable law, the Services are provided "as is" and "as available", without warranties of any kind, whether express, implied, or statutory, including warranties of merchantability, fitness for a particular purpose, non-infringement, and any warranty arising from course of dealing or usage. We do not warrant that the Services will be uninterrupted, error-free, secure, or free of harmful components, or that Outputs will be accurate, complete, or appropriate for any purpose. We are not responsible for any loss of data or learning progress resulting from technical issues.

13. Limitation of Liability

To the fullest extent permitted by applicable law, Savantiva will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, data, goodwill, or business, arising out of or related to these Terms or the Services, even if advised of the possibility of such damages. Savantiva's total aggregate liability arising out of or related to these Terms or the Services will not exceed the greater of the total amount you paid for access to the Services — whether to us or to Paddle or an app store acting on our behalf — in the 12 months preceding the event giving rise to the claim, and US$100.

Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law, including liability for death or personal injury caused by negligence, or for fraud. Mandatory statutory consumer rights are not affected by this Section.

14. Suspension and Termination

We may suspend or terminate your access to the Services if you violate these Terms, engage in fraudulent or harmful activity, or where required to comply with law. We will provide notice where practicable, except where immediate action is necessary to protect the Services or others. You may delete your account at any time through your account settings; upon deletion, your personal data will be handled as described in our Privacy Policy. Any fees accrued before termination remain due. Provisions that by their nature should survive termination will survive.

15. Governing Law, Disputes, and Consumer Rights

These Terms are governed by the laws of the Republic of Türkiye, without regard to conflict-of-law principles. Subject to the mandatory consumer provisions below, the courts and execution offices of Istanbul, Türkiye have jurisdiction over any dispute arising out of or relating to these Terms or the Services.

Mandatory consumer protections. Nothing in this Section deprives you of the protection of the mandatory consumer-protection law of your country of habitual residence. If you are a consumer in Türkiye, you retain your right under Law No. 6502 on the Protection of Consumers to apply to the competent Consumer Arbitration Committee ( Tüketici Hakem Heyeti) or Consumer Court (Tüketici Mahkemesi) at your place of residence. If you are a consumer in the European Union, the mandatory consumer-protection rules of your country of residence continue to apply, and you may bring your dispute before a competent alternative dispute resolution (ADR) body in your country of residence.

16. Business Transfers

If Savantiva is involved in a merger, acquisition, financing, reorganisation, or sale of assets, these Terms and your data may be transferred to the acquiring entity. We will notify you before your data becomes subject to a materially different privacy policy.

17. Changes to These Terms

We may update these Terms from time to time. For material changes, we will provide notice, for example by email, at least 14 days before the changes take effect. Your continued use of the Services after that date constitutes acceptance of the updated Terms. If you do not agree, you must stop using the Services before the changes take effect.

18. General

Severability. If any provision of these Terms is found unenforceable, the remaining provisions remain in effect, and the unenforceable provision will be modified to the minimum extent necessary to make it enforceable.

Waiver. Our failure to enforce any provision is not a waiver of our right to do so later.

Assignment. You may not assign these Terms without our prior written consent. We may assign these Terms in connection with a merger, acquisition, or sale of assets.

Force majeure. We are not liable for any delay or failure to perform resulting from causes beyond our reasonable control.

Entire agreement. These Terms, together with our Privacy Policy, constitute the entire agreement between you and Savantiva regarding the Services and supersede any prior agreements.

Language. These Terms were originally written in English. If we provide a translation, the English version controls in the event of conflict, to the extent permitted by the mandatory consumer-protection law of your country of residence.

19. Copyright Infringement Notices

If you believe content on the Services infringes your copyright, submit a written notice to legal@savantiva.com including: your contact details; identification of the copyrighted work and of the allegedly infringing material and its location on the Services; a statement that you have a good-faith belief the use is not authorised; a statement that the information in your notice is accurate and that you are the copyright owner or authorised to act on their behalf; and your signature. Upon receiving a valid notice, we may remove or disable access to the material and notify the affected user, who may submit a counter-notice. We terminate the accounts of repeat infringers where appropriate.
