Terms of service

These Terms govern your use of TangoLango (www.tangolango.com and the TangoLango mobile app), a service operated by NMajor Studios LLC (a Wyoming, USA limited liability company) ("we", "us"). By using TangoLango you agree to these Terms.

1. What TangoLango provides

TangoLango is a European Portuguese learning app with daily spaced-repetition lessons, synthesized audio, optional illustrations, and an AI tutor. AI-generated content is for personal study use.

2. Subscriptions and payments

Paid subscriptions will be sold through the Apple App Store and Google Play. The app will show the current price, billing period, renewal terms, and any trial before purchase. Apple or Google processes payment and provides purchase management under its own terms. We do not store your card details.

3. Your content and license

Sentences, audio, and images generated for your account are licensed to you for personal study. You may not resell them or present TangoLango as your own service. Words and situations you submit remain yours; you grant us the license needed to operate the service for you.

4. AI-generated content

Study content is produced by automated systems and, while we run dialect and quality checks, it may occasionally contain errors. It is provided for learning purposes and without warranty of accuracy. If something looks wrong, tell your tutor. Corrections feed back into your deck.

5. Acceptable use

Don't use TangoLango to break the law, infringe others' rights, abuse the tutor for non-learning bulk generation, or attempt to disrupt or reverse-engineer the service. Tutor messaging has fair-use daily limits. We may suspend access for misuse.

6. Refunds

See our refund policy. Store purchases and refund requests follow Apple or Google procedures, without limiting statutory consumer rights.

7. Disclaimers & liability

TangoLango is provided "as is" without warranties of any kind. To the maximum extent permitted by law, NMajor Studios LLC's total liability for any claim relating to the service is limited to the amounts you paid in the twelve months before the claim.

8. Children

TangoLango is not directed to children. You must be at least 13 years old (or, in the EU/EEA, at least 16, or the age of digital consent in your country) to use TangoLango.

9. Changes

We may update these Terms; material changes will be reflected by the "Last updated" date above. Continued use means you accept the updated Terms.
