Terms of Use & Privacy Policy

Effective Date: September 29, 2026
Last updated: November 9, 2026

App: MapleLingo
Developer Name (on Google Play): Natvas Studio

MapleLingo is published on Google Play under the developer name Natvas Studio. For the purposes of these Terms and Privacy Policy, references to "we," "our," or "us" refer to the individual developer who publishes MapleLingo under this name.

1. Eligibility & Account

• You must be at least 18 years old (or the minimum legal age of digital consent in your jurisdiction) to use MapleLingo.
• Sign-in is by email and password, verified through our secure authentication provider; Google Sign-In is available where offered. No other account types are supported.
• You are responsible for maintaining the confidentiality of your account credentials.
• MapleLingo automatically assigns you a public username (a random letters-and-numbers handle, not your real name) at sign-up. You may change it at any time from Profile, subject to a content check and a 30-day limit between changes.

2. Purpose of the App

MapleLingo is your AI-powered English learning companion, turning any topic, word list, or grammar focus you choose into a personalized reading lesson.

• Describe a topic, add your own vocabulary, or pick a grammar/vocabulary focus, and get a lesson generated for your English level.
• Read it your way: a paced, Guided walkthrough with built-in checkpoints, or free-form Explore reading.
• Practice what you've learned with review questions drawn from your own lessons and lessons like them.
• Discover lessons other learners have published, and save or like the ones you find useful.
• Keep track of everything you've created and saved in your own Library.

MapleLingo is designed to make everyday curiosity – a topic, a phrase, a word you keep mixing up – into a genuinely useful English lesson in seconds.

3. Disclaimer

Lesson text, explanations, and practice questions in MapleLingo are generated with the help of AI, combined with other language-processing tools, and are intended for personal language-learning practice only. They do not constitute professional instruction, certification, or a substitute for a qualified English teacher or examination body. We make no guarantee that this generated content will always be accurate or complete. You are solely responsible for how you use the App's content. The developer of MapleLingo (publishing under the name Natvas Studio) is not liable for any loss, harm, or damages arising from the use of this app or reliance on its content.

4. User Responsibilities

• Not use the app for unlawful or harmful purposes.
• Not copy, reverse engineer, or distribute the app's content or underlying systems.
• Use the app only for personal, non-commercial language learning unless we provide prior written consent.
• Not submit, as a topic, vocabulary, or username, content that is illegal, hateful, sexually explicit, or otherwise inappropriate for a general audience – especially anything you intend to publish for other learners.
• Not impersonate another person or misrepresent your affiliation with anyone.

We may remove content, reject a chosen username, or suspend or terminate accounts that violate these Terms.

5. Subscriptions & Purchases

• New accounts can create a limited number of lessons for free. Once that limit is reached, creating additional lessons requires an active subscription, where offered.
• All purchases and subscriptions are processed securely through Google Play Billing.
• MapleLingo Premium lets you create new lessons without the free limit. The price and billing period are shown in the App before you subscribe and on Google Play's purchase screen.
• Automatic renewal. Your subscription renews automatically at the end of each billing period, and your Google Play account is charged the then-current price, until you cancel.
• Free trials. If a free trial is offered, you won't be charged if you cancel before it ends; otherwise the regular price is charged when it ends.
• Cancelling. You can cancel anytime in the Google Play Store app under Payments & subscriptions → Subscriptions. You keep Premium until the end of the period you've already paid for; partially used periods are not refunded by us.
• We do not collect or store your credit card, banking, or payment account details.
• We store limited purchase metadata (subscription status, product identifier, purchase token, renewal date) for validating subscriptions and enabling access.
• Subscription cancellations, refunds, and billing disputes are handled through Google Play, not directly by us.

6. Information We Collect

a. Personal Identifiers

• Email address (used for sign-in and account-related communication)
• Auto-generated public username (shown on lessons you publish; your email is never shown to other users)

b. Learning Data

• Your English level (chosen during onboarding, or estimated from lessons you've created, liked, or saved)
• Topics, custom vocabulary, and learning-focus selections you provide when creating a lesson
• Lesson text and exercises generated for you, and your progress and practice history through them

c. App & Operational Data

• Standard server logs (error logs, request timestamps) generated by our cloud infrastructure to keep the App running and diagnose problems
• We do not use third-party advertising or analytics-tracking SDKs

d. Public Content

• Lessons you choose to make public, and your username, visible to other learners through the Discover feed; like/save counts are aggregate and don't reveal who liked or saved something

e. Purchases & Subscriptions

• Subscription status and purchase metadata (see Section 5)

7. How We Use Your Data

• Generate lesson content tailored to your chosen topic, vocabulary, level, and learning focus.
• Authenticate your account, apply your free-lesson limit, and manage subscriptions.
• Power your Discover feed, practice review queue, and progress indicators.
• Keep the App secure and diagnose technical problems.
• Contact you at your registered email regarding important account, subscription, or purchase issues.

We do not sell your personal information, and we do not use it for third-party advertising.

8. How Your Lessons Are Generated

MapleLingo generates lesson text, explanations, and practice questions with the help of AI language models, combined with rule-based language-analysis tools that check grammar and vocabulary – not a single AI system working alone. To generate and search your lessons, these tools process:

• The topic, custom vocabulary, and learning-focus selections you provide
• Your chosen English level and lesson style
• A short search summary of a lesson's content, used to power Discover

Your email address, username, or any other account identifier is never sent as part of this processing. Content you submit is not used to train any third-party AI models. Before a lesson can be made public, its content – and any username you choose – is automatically screened for inappropriate material; content that fails this check stays private.

9. Data Processing & Sharing

We rely on trusted third-party providers to operate MapleLingo and deliver its features:

• Cloud infrastructure providers – authentication, database storage, and secure cloud processing
• AI language-model providers – lesson generation and search (see Section 8)
• Google – Google Sign-In (where offered) and Google Play Billing for subscriptions

These providers may process certain data to provide their services to us. Their processing may be governed by their own privacy policies and terms. We do not sell your personal information and we do not rent your data.

10. Data Security

• All communication is encrypted via HTTPS.
• Data is encrypted at rest and stored in secure cloud services with restricted, per-service access.
• While we use industry-standard safeguards, no system is 100% secure. You use the app at your own risk.

11. Account & Data Deletion

You can permanently delete your account at any time, directly in the app, from Profile → Delete account – no need to email us. This immediately and irreversibly deletes:

• Your personal account information (email, credentials)
• Your private lessons
• Your own likes and saves

Lessons you've published publicly remain visible to other learners, who may have already seen, liked, or saved them, but are reassigned to a generic placeholder account and are no longer linked to your identity. This action cannot be undone.

Note: limited records may be retained if required by law (e.g., for tax or accounting compliance).

12. Children's Privacy

MapleLingo is not directed to children. We do not knowingly collect data from users under the age of 18 (or the minimum age of digital consent in their country). If you believe we have collected such information, please contact us at natvas.studio@gmail.com, and we will delete it promptly.

13. Your Rights

Depending on your jurisdiction (e.g., GDPR, CCPA), you may have the right to:

• Access your personal data
• Request correction or deletion
• Object to or restrict certain processing
• Withdraw consent (where applicable)

You may exercise these rights by contacting us at natvas.studio@gmail.com, or by using the in-app account deletion described in Section 11.

14. Limitation of Liability

• The app and its content are provided "as is" without warranties.
• We are not liable for any indirect, incidental, or consequential damages.
• We do not guarantee uninterrupted service or the accuracy of generated lesson content.

15. Updates to this Policy

We may update these Terms and Privacy Policy from time to time. Updates will be posted in the app and/or on the app store listing. Continued use of MapleLingo after updates means you accept the revised terms.
