Terms of Service

1. Who we are

ChatLingo is operated by ChatLingo, based in Singapore. You can reach us at chatlingo.co@gmail.com.

By creating an account or using the service you accept these terms. If you do not accept them, do not use the service.

2. Eligibility and accounts

• You must be at least 13 years old to hold an account. If you are under the age of majority where you live, you may only use the service with the involvement of a parent or guardian, who accepts these terms on your behalf.
• You are responsible for everything that happens under your account, including keeping your sign-in credentials secure. Tell us promptly if you believe your account has been accessed without your permission.
• One account per person. Accounts are personal and may not be shared, sold or transferred.
• Where your school or employer provides you access through an organization, that organization may be able to see your participation and progress within its own scenarios.

3. What the service is — and is not

ChatLingo provides conversational language practice with an AI partner, along with automated feedback, translation, speech synthesis and progress tracking.

4. Free tier, energy and Premium

• The service has a free tier that meters practice attempts using an in-app allowance called energy. Free accounts start with a set amount of energy and replenish a limited amount each day.
• Energy, experience points, streaks, achievements and any other in-app items have no monetary value, are not property, cannot be exchanged for cash and cannot be transferred between accounts.
• Premium is a paid subscription that removes the energy limit. It remains subject to a fair-use ceiling intended to prevent automated abuse; we may contact you before applying any limit to genuine personal use.
• We may change the amount of energy granted, the cost of an action, or the contents of the free and paid tiers. Where a change materially reduces what you have already paid for, we will give you notice and you may cancel under the Refund Policy.

5. Subscriptions, billing and renewal

Payments are processed by Stripe. We do not receive or store your full card details.

• Prices are shown at checkout in the currency listed there, and may exclude taxes that apply where you live.
• We may change subscription prices. Existing subscribers will be notified before a change takes effect and may cancel before the next renewal rather than accept the new price.
• If a payment fails, we may retry it and may suspend Premium access until payment succeeds.
• Refunds are governed by our Refund Policy, which forms part of these terms.

6. Acceptable use

You agree not to:

• Use the service to generate or share content that is unlawful, hateful, harassing, sexually explicit involving minors, or that infringes someone else's rights.
• Attempt to extract, scrape, resell or redistribute the service's model outputs, scenario content or datasets, or use them to train a competing model.
• Automate access, circumvent energy limits or rate limits, or use multiple accounts to obtain free usage beyond what the free tier provides.
• Probe, disrupt or overload the service or its infrastructure, or access another user's account or data.
• Upload audio of a person who has not consented to being recorded.

We may suspend or terminate accounts that breach this section, and may remove content that does so.

7. Your content

You keep ownership of what you write, say and create in the service, including practice transcripts, voice recordings and scenarios you author. You grant us a worldwide, non-exclusive, royalty-free licence to host, process, transmit and display that content solely to operate and improve the service — for example, sending a message to a language model to produce a reply, or generating your progress summaries.

If you publish a scenario so that other users can practise it, you additionally grant those users the right to use it within the service. You are responsible for having the rights to any content you publish.

8. Our intellectual property

The service, including its software, interface, curriculum structure, avatars and branding, belongs to ChatLingo or its licensors. These terms grant you a personal, revocable, non-transferable right to use the service, and nothing more.

9. Suspension and termination

You may stop using the service and delete your account at any time. We may suspend or terminate your access if you breach these terms, if required by law, or if continuing to provide the service to you would expose us or other users to material risk. If we terminate your account without cause while you hold a paid subscription, we will refund the unused portion of the period you have paid for.

10. Disclaimers

To the fullest extent permitted by law, the service is provided “as is” and “as available”, without warranties of any kind, whether express or implied, including fitness for a particular purpose, accuracy of automated output, or uninterrupted availability. Nothing in these terms excludes liability that cannot lawfully be excluded, including any statutory consumer guarantees available to you.

11. Limitation of liability

To the fullest extent permitted by law, we are not liable for indirect, incidental, special or consequential loss, or for loss of data, profits, opportunity or goodwill. Our total aggregate liability arising out of or relating to the service is limited to the greater of the amount you paid us in the twelve months before the event giving rise to the claim, or SGD 100.

12. Changes to these terms

We may update these terms as the service develops. If a change is material we will give reasonable notice — for example, in the app or by email — before it takes effect. Continuing to use the service after that point means you accept the updated terms.

13. Governing law

These terms are governed by the laws of Singapore, and the courts of Singapore have exclusive jurisdiction over any dispute. If you are a consumer resident elsewhere, this does not deprive you of the protection of mandatory consumer laws in your country of residence.
