Terms of Use

Last updated: 9 November 2026

These terms apply when you use 2lingua.com and the 2Lingua app. By creating an account or using the site you agree to them. Please read them together with our Privacy Policy.

1. The service

2Lingua offers language-learning tools, including conversations with an AI partner, lessons, stories, podcasts, a phrasebook and free articles. Some features are free; others need a paid subscription (section 3). We may add, change or remove features at any time.

2. Your account

  • You must be at least 16 years old to create an account.
  • Give a valid email address and keep your password private. You're responsible for activity on your account.
  • One person, one account. Don't create accounts automatically or to manipulate leagues or leaderboards.
  • You can delete your account at any time from your profile.

3. Subscriptions and payment

  • Plans. The subscription costs $7 per month or $49 per year (prices in US dollars; your local price and any tax are shown at checkout). It includes up to 30 minutes of voice conversation with Lina per day (resetting at 00:00 UTC), unlimited text conversations, full report cards, the full vocabulary garden and phrasebook, and the personal plan.
  • Free features. Without a subscription you can read articles, stories and podcasts, use a starter phrasebook, keep up to 20 words in your garden, and have one text conversation with Lina of up to 3 minutes.
  • Payment. Our order process is conducted by our online reseller Paddle.com. Paddle.com is the merchant of record for all our orders and handles billing, tax and customer service questions about payments.
  • Renewal and cancellation. Subscriptions renew automatically until you cancel. You can cancel any time from your account page; you keep access until the end of the period you've paid for.
  • Failed payments. If a renewal payment fails, you keep access for 3 days while you update your payment method; after that, paid features pause until payment succeeds.
  • Refunds. If you haven't used voice conversations, you can ask for a full refund within 7 days of your first payment. This doesn't affect your statutory rights.
  • Fair use. The daily voice limit exists because each minute of voice AI has a real cost. Automated or shared use of one account isn't allowed.

4. Acceptable use

You agree not to:

  • use 2Lingua for anything unlawful, or to harass, threaten or impersonate others;
  • choose a display name that is offensive or misleading;
  • try to cheat XP, streaks or leagues, for example with scripts or by tampering with requests;
  • attempt to access other people's accounts, probe or disrupt our systems, or scrape the site at scale;
  • use the AI conversation feature to generate harmful content or to try to extract its instructions.

We may suspend or delete accounts that break these rules.

5. AI conversations

Lina is an AI. Her replies are generated automatically and can be wrong, incomplete or unnatural. Use them for practice, not as professional, legal, medical or translation advice. Don't share sensitive personal information in conversations.

6. Content and intellectual property

The 2Lingua name, logo, app, stories, podcasts, lessons and articles belong to 2Lingua or its licensors. You may read and use them for your own personal learning, and you may quote short extracts with a link back. Don't copy, republish or sell them without our written permission.

Your conversation messages remain yours. You give us permission to store and process them to provide the service to you.

7. Advertising and third-party links

Public pages may show ads provided by Google. We aren't responsible for the content of ads or third-party websites linked from 2Lingua.

8. Disclaimers

We work hard to keep 2Lingua accurate and available, but the service is provided "as is", without guarantees that it will be uninterrupted, error-free or that you'll reach a particular level. Progress, XP and streaks have no monetary value.

9. Liability

To the extent permitted by law, 2Lingua isn't liable for indirect or consequential losses, or for loss of data or progress. Nothing in these terms limits liability that cannot be limited by law, including your statutory rights as a consumer.

10. Changes and contact

We may update these terms. If a change is important we'll tell signed-in users in the app before it takes effect. Questions? Contact us.
