Terms & Privacy
The small print, kept as human as we could make it. Last updated 7 July 2026.
1. Introduction
Welcome to AI LingoPlay, an AI-based role-play app designed to help users practise their language skills through interactive role-play scenarios with an AI character. AI LingoPlay is operated by an individual developer based in the United Kingdom, not a registered company. By using our app, you agree to comply with and be bound by the following terms and conditions. Please review them carefully. By using AI LingoPlay, you agree to these terms.
2. Service Description
AI LingoPlay enables users to select a language, choose a difficulty level, pick a character to interact with, and engage in role-play scenarios. Users can hear the character speak, see responses as text, and respond using text or voice. The AI can analyse user messages for feedback, suggest responses, translate content, break down the grammar of the AI character's responses, and provide end-of-scene reviews and personalised learning tips.
AI LingoPlay is a practice tool, not a language course. Features may be added, changed or retired over time as the app develops.
3. Accounts and Eligibility
3.1 Age
You must be at least 13 years old to use AI LingoPlay. If you are under 18, you may only use the app with the permission of a parent or guardian, and any subscription must be purchased by an adult on your behalf. While we aim to keep every conversation appropriate, responses are AI-generated and we cannot guarantee their suitability in every case.
3.2 User Accounts
To use the app you must register an account with a valid email address. Sign-in is handled by Auth0, our authentication provider. You are responsible for maintaining the confidentiality of your login credentials and for all activity under your account. Accounts are personal and should not be shared. If you believe your account has been compromised, please contact us immediately.
4. Subscriptions and Payments
4.1 The Plan
AI LingoPlay is offered as a single monthly subscription (currently US$2.50 per month). The exact price is always shown before you confirm payment at checkout. Payments are processed securely by Stripe; we never see or store your card details.
4.2 Renewal and Cancellation
Your subscription renews automatically each month until you cancel. You can cancel at any time from the account menu in the app (via “Manage Subscription”, which opens our secure Stripe billing portal) — no emails, no phone calls, no guilt trips. When you cancel, your access continues until the end of the period you have already paid for, and you will not be charged again.
4.3 Free Trials
We do not currently offer a free trial. If we introduce one in future, its conditions will be shown at checkout.
4.4 Failed Payments
If a renewal payment fails, Stripe will retry it automatically. If payment cannot be collected, your subscription and access to the app may be suspended until payment is resolved.
4.5 Price Changes
We may change the subscription price in future. If we do, existing subscribers will be given advance notice by email or in the app before any new price takes effect, and you can cancel before your next renewal if you do not wish to continue at the new price.
4.6 Refunds
Because the subscription is billed monthly with no minimum term, partial refunds for unused time are not normally offered. By starting your subscription you consent to the service beginning immediately, which may affect any statutory cooling-off period; your statutory rights as a consumer are otherwise unaffected. If you believe you have been charged in error, please contact us and we will put it right.
4.7 Fair Use
Your subscription includes unlimited role-play conversations for genuine personal language practice. Because every AI response has a real cost, we apply reasonable fair-use safeguards — for example, limits on the number of messages within a single conversation — and we may restrict automated, scripted or clearly abusive usage patterns. These safeguards exist to keep the price low for everyone.
5. User Conduct
5.1 User Responsibilities
The app is intended solely for practising language skills through role-play. Users should not attempt to use it as a generic AI assistant. Users must use the app in a lawful, respectful manner and in accordance with these terms and conditions.
5.2 Prohibited Activities
Users are prohibited from generating harmful content, including but not limited to hate speech, harassment, or violence. Any misuse of the app for such purposes is strictly forbidden. Additionally, users must not engage in activities that could harm or disrupt the app, its services, or its users, including attempting to circumvent usage limits or security measures.
6. Privacy and Data Handling
6.1 Data Collection
When you create an account, we collect and store your email address and name (via Auth0), your language preferences and conversation settings, your conversation history, and learning data such as feedback and personalised tips. This data is stored securely and used solely to personalise your experience and enable the core functionality of the app.
6.2 Data Usage
We use your data to deliver personalised language learning experiences, store your conversation history and progress, process your subscription, and provide support. Your data is not sold, and is not shared with third parties except as required to provide core services (see below).
6.3 Third-party Services
AI LingoPlay is built on trusted third-party services, each of which may process data as required to fulfil its function:
• OpenAI — AI role-play conversations, language analysis and speech-to-text. OpenAI retains API data for up to 30 days for abuse prevention, and does not use it for training unless explicitly opted in.
• Google Cloud — text-to-speech and translation.
• Auth0 — account creation and sign-in.
• Stripe — subscription payments; Stripe handles your card details, we never see them.
• SendGrid — transactional email such as welcome and account messages.
• Sentry — error monitoring, so we can find and fix bugs.
• Google Analytics — anonymous usage statistics that help us understand how the site is used.
Users are encouraged to review the privacy policies of these providers.
6.4 Cookies and Local Storage
With your consent, we save your language settings and preferences to your browser's local storage so the app remembers you between visits; if you decline, they are kept only for your current session. We also use cookies required for signing in and keeping your session secure, and Google Analytics may set cookies to measure site usage. You can change your storage choice at any time via the “Privacy setting” link in the footer.
6.5 Data Storage and Security
Account-related data is stored securely on our servers and protected by standard encryption practices. Conversation history and learning data are retained while your account is active so that your practice can build over time.
6.6 Data Access and Deletion
You may request to access, correct, or delete your account data at any time by contacting us. Account deletion requests will result in permanent removal of your data from our systems, except where retention is required for legal or accounting reasons (for example, payment records held by Stripe).
7. Intellectual Property
7.1 Content Ownership
The AI-generated content during role-play scenarios is treated as temporary and non-proprietary. We do not claim ownership over user interactions or generated messages. The AI LingoPlay name, logo, design and scenario content remain our property.
7.2 Licences
By using the app, you do not grant any licences to AI LingoPlay for the use of your content beyond what is required to deliver the service.
8. Liability and Disclaimers
8.1 AI-generated Content
AI LingoPlay is not responsible for the content generated by OpenAI or other third-party providers. While we aim to create an engaging and appropriate experience, we cannot guarantee the suitability or correctness of all AI-generated responses. Corrections, translations and grammar explanations are automated and may occasionally be wrong — a good reminder that even AI characters are still learning.
8.2 Not Professional Advice
Role-play scenarios may involve characters such as doctors, pharmacists or officials. These are language exercises only; nothing said by an AI character should be relied on as medical, legal, financial or other professional advice.
8.3 Warranty Disclaimer
The service is provided “as is” and without warranty of any kind. We do not warrant that the app will be free from bugs or uninterrupted — though as a one-person project, we take both personally. To the fullest extent permitted by law, our total liability to you is limited to the amount you paid us in the twelve months before the claim arose. Nothing in these terms limits liability that cannot be limited by law.
9. Changes and Termination
9.1 Modifications
We may update these terms from time to time. Material changes will be communicated via the app or email. Continued use of the service after changes are made constitutes acceptance of the updated terms.
9.2 Termination
We reserve the right to terminate or suspend accounts that violate these terms or engage in misuse of the service. If we terminate your account without cause, we will refund any remaining paid period. Users may also request to close their account at any time by contacting us.
9.3 If the Service Ends
If AI LingoPlay ever shuts down permanently, subscribers will be notified in advance, billing will stop, and any remaining paid period will be honoured or refunded.
10. Contact Information
If you have questions about these terms, your subscription, or your data, please contact us — you will be talking directly to the person who built the app.
11. Legal Jurisdiction
These terms are governed by the laws of England and Wales, and any disputes are subject to the jurisdiction of its courts. Nothing in these terms affects any mandatory consumer rights you have in your country of residence.
