Terms of Service
Last updated: 23 September 2026
1. The Service
Saga is an AI-powered language learning service that provides interactive conversations, feedback, and learning features. The Service is offered as a research preview and may change over time, including the features available and the quality or style of AI responses.
2. Eligibility
You must be at least 16 years old to use the Service. By using the Service, you represent and warrant that you meet this requirement.
3. Accounts and security
You are responsible for maintaining the confidentiality of your account credentials and for all activity under your account.
You may not share, sell, or transfer your account or subscription to others. We may suspend or terminate accounts that appear to be used by multiple people.
4. Subscriptions, free trial, billing, and cancellation
4.1 Plans
We may offer monthly and three-month subscription plans (“Subscription”). Plan details, pricing, and billing frequency are shown at checkout.
4.2 Free trial
If eligible, your Subscription includes a 7-day free trial. Unless you cancel before the trial ends, your payment method will be charged automatically at the end of the trial and your Subscription will begin.
We may limit free trials (for example, to first-time subscribers).
4.3 Auto-renewal
Subscriptions renew automatically at the end of each billing period (monthly or every three months) unless you cancel before renewal.
4.4 Billing and payment processing
Authentication/account access is handled via Clerk and payments are processed by Stripe (together, “Payment Providers”).
By starting a Subscription, you authorize us and the Payment Providers to charge your selected payment method on a recurring basis in accordance with your chosen plan.
If a payment fails, we may retry the charge and suspend access until payment is received.
Subscriptions and one-time purchases made in our iPhone or Android app are sold and billed by Apple through the App Store or by Google through Google Play, under their terms, and not by Stripe.
4.5 How to cancel
You can cancel at any time. A subscription bought on our website is cancelled in your account settings; a subscription bought in our iPhone or Android app is cancelled in your App Store or Google Play subscription settings. Cancellation stops future renewals.
4.6 Lifetime Plan
We may offer a one-time payment option that grants access to the Service for the lifetime of the product (“Lifetime Plan”).
The Lifetime Plan provides access to the Service for as long as Saga is commercially available, it does not guarantee access for the purchaser's lifetime. If Saga ceases operations or discontinues the Service, access under the Lifetime Plan will end. Where possible, we will provide at least 30 days' notice before any such discontinuation.
The features, content, and functionality available under the Lifetime Plan may change over time. We reserve the right to add, modify, or remove features, including AI-powered features, without prior notice.
5. 14-day cancellation and refunds (consumers)
If you are a consumer and you cancel within 14 days of your first successful payment, you will receive a full refund of amounts paid for the then-current subscription period, even if you have started using the Service. This is in addition to (and does not limit) any mandatory consumer rights that apply.
If you cancel within 14 days, we may end your access to the Service immediately upon cancellation and refund you.
To request a cancellation/refund, use the in-app cancellation flow (if available) or contact felix@saga.study from the email address associated with your account.
Purchases made through the App Store or Google Play are refunded by Apple or Google under their refund policies; request those refunds from Apple or Google.
6. User content, transcripts, and personalization
6.1 Your content
You retain ownership of content you submit to the Service, such as messages, prompts, and audio (“User Content”).
6.2 Transcripts and learning data
We store conversation transcripts and learning-related data to provide the Service and personalize your learning experience (for example, adapting difficulty, feedback, and recommendations).
6.3 License to operate the Service
You grant us a worldwide, non-exclusive, royalty-free license to host, store, reproduce, process, and display your User Content solely to provide, maintain, secure, and improve the Service and to comply with law.
6.4 Voice samples for speech recognition improvement
We may collect and store short voice recordings from your conversations to evaluate and improve the speech recognition used in the Service. How this works depends on your account type:
- Research preview / credited users: Voice samples may be collected automatically as part of the research preview. By using the Service under a research preview or credited access grant, you consent to this collection.
- Subscribers: Voice samples are only collected if you opt in via the “Help make Saga better” setting in your account. You can turn this off at any time, and we will stop collecting new samples.
Collected voice samples are stored securely and used only to benchmark and improve speech recognition accuracy across languages and proficiency levels. They are not used to train general-purpose AI models (see Section 7). Voice samples are not shared with third parties except as necessary to operate the Service (see Section 11).
You may request deletion of your stored voice samples at any time by contacting felix@saga.study.
7. No training on user content (current practice)
As of the Effective date of these Terms, we do not use your transcripts to train general-purpose AI models. If this changes, we will update these Terms and/or our Privacy Policy and provide notice before the change takes effect.
8. AI limitations and disclaimers
The Service uses AI to generate conversations and feedback. AI output may be inaccurate, incomplete, misleading, or inappropriate. You are responsible for how you use the output and for verifying it when necessary.
The Service is provided for educational purposes and does not provide medical, legal, financial, or other professional advice.
We do not guarantee any particular learning outcomes, fluency level, test results, or progress.
9. Acceptable use
You agree not to misuse the Service. You must not:
- violate any law or regulation;
- infringe intellectual property, privacy, or other rights;
- harass, abuse, threaten, or exploit others;
- attempt to bypass paywalls, subscription checks, usage limits, or security;
- reverse engineer, scrape, or interfere with the Service (except as permitted by mandatory law);
- upload or submit content you do not have the right to use.
We may suspend or terminate access if you violate these Terms or misuse the Service.
9.1 Community content and abusive behaviour
Parts of the Service let you show other learners a profile (your username, bio and avatar), add friends, and send them short messages. We have no tolerance for objectionable content or abusive users. You must not use any of these to post or send content that is hateful, harassing, threatening, sexually explicit, violent, discriminatory, fraudulent, or otherwise offensive or unlawful, and you must not use them to abuse, impersonate or harass other people.
Profile text is filtered for offensive words. You can report any learner's profile and block any learner from within the app; blocking hides you from each other immediately and notifies us. We review every report within 24 hours and remove objectionable content and eject the user who provided it, without notice and at our sole discretion.
10. Intellectual property
The Service, including its software, design, text, and trademarks, is owned by us or our licensors and is protected by applicable laws. We grant you a limited, personal, non-transferable, revocable license to use the Service in accordance with these Terms.
11. Third-party services
The Service relies on third-party services (including the Payment Providers, hosting, analytics, and AI providers). We are not responsible for outages or failures caused by third parties.
12. Changes to the Service and Terms
We may modify or discontinue parts of the Service at any time.
We may update these Terms from time to time. If changes are material, we will provide reasonable notice (for example, by email or in-app notice). Continued use after the effective date means you accept the updated Terms.
13. Limitation of liability
To the maximum extent permitted by applicable law, we will not be liable for indirect, incidental, special, consequential, or punitive damages, or for loss of profits, revenues, goodwill, or data.
Our total liability for any claim arising out of or relating to the Service will not exceed the amounts you paid for the Service in the 12 months before the event giving rise to the claim.
Nothing in these Terms limits liability that cannot be limited under applicable law (including mandatory consumer rights, fraud, or willful misconduct).
14. Governing law and disputes
These Terms are governed by the laws of Sweden. If you are a consumer, mandatory consumer protection rules in your country of residence may also apply.
