Privacy Policy

Last updated: October 2026

Tonguelane ("we", "us") helps people learn spoken languages. This policy explains what we collect and how we use it.

What we collect

• Account details: your name, email address and password (stored securely, we never see your password). If you sign in with Google, Apple or Facebook we receive your name and email from them.
• Learning data: your word lists, saved sentences, grades, progress and settings.
• Voice: when you use the voice chat, your recording is sent to our speech-to-text provider to be turned into text. We do not keep the recordings.
• Chat messages: what you type or say to the AI partner is sent to our AI provider to produce a reply.

How we use it

To run the app, save your progress, give you replies and corrections, keep the service secure, and contact you about your account. We do not sell your personal data and we do not show ads.

Who processes it

We use trusted providers to run the service: Supabase (database and sign-in), Anthropic (AI replies and translations), ElevenLabs (speech) and Netlify (hosting). Payments, when introduced, are handled by Stripe and we never see your card number.

Your choices

You can ask us to export or delete your account and data at any time by emailing support@tonguelane.com. We will respond within 30 days.

Children

Tonguelane is not intended for children under 13.

Terms of Service

Last updated: October 2026

By creating an account or using Tonguelane you agree to these terms.

Using the service

You may use Tonguelane for personal learning. Do not misuse the service, attempt to break or overload it, copy its content at scale, or use it to produce unlawful or abusive material.

Your account

You are responsible for keeping your login secure and for activity on your account. You must be at least 13 years old.

AI and learning content

Translations, example sentences and AI conversation are generated automatically and may contain mistakes. Spoken dialects vary by region and speaker. Use Tonguelane as a learning aid, not as a certified translation.

Subscriptions and payments

Some features may require a paid plan. Prices are shown before you subscribe. Subscriptions renew until cancelled, and you can cancel at any time; access continues to the end of the paid period. Refund requests can be sent to support@tonguelane.com.

Availability and changes

We work to keep the service running but cannot guarantee it will always be available. We may change or discontinue features, and may update these terms; continued use means you accept the updated terms.

Ending your account

You can stop using Tonguelane and ask us to delete your account at any time. We may suspend accounts that break these terms.

Liability

The service is provided "as is". To the extent permitted by law, we are not liable for indirect or consequential losses arising from your use of it.
