Inmersy

Privacy Policy

Last updated: July 29, 2026

Inmersy ("we", "our", "the Service") is an AI-powered language tutor. This Privacy Policy explains what data we collect, how we use it, and your rights regarding your personal information.

1. Data We Collect

Account Information

  • Name — your name as provided by your Google account when you sign up
  • Email address — from your Google account, used for authentication, account recovery, and support
  • Phone number — collected during onboarding so your teacher can reach you personally to help you get started with the app and answer any questions. Stored in international E.164 format (e.g. +34612345678). Never used for marketing, never shared with third parties for advertising, never sold. Legal basis: legitimate interest in providing personal onboarding support (GDPR Art. 6.1.f).
  • Language level and learning goals — provided during onboarding to personalize your experience
  • Native language — used to provide explanations in your language

WhatsApp Contact (opt-in)

  • During onboarding you may optionally tick a box allowing your teacher to contact you via WhatsApp for onboarding help and support. The box is unchecked by default — ticking it is a specific, informed, freely given consent (GDPR Art. 6.1.a).
  • If you consent, your phone number may be sent to WhatsApp / Meta Platforms Ireland Ltd. as a data processor so we can initiate a conversation. Meta's processing is governed by its own WhatsApp Privacy Policy.
  • You can revoke consent at any time from Settings → Notifications → WhatsApp. Revocation takes effect immediately for future outbound messages; message history already exchanged in WhatsApp is not deleted from your phone or ours by the toggle (delete individual messages in the WhatsApp app for that).

Conversation Data

  • Chat messages — your text conversations with the tutor are stored temporarily to maintain conversation context and provide personalized feedback
  • Retention period: 30 days — conversations are automatically and permanently deleted after 30 days

Voice Data

  • Audio files are NOT stored — voice messages you send are processed in real time for speech-to-text transcription and immediately discarded
  • Voice metadata (transcription text, duration) is stored temporarily and automatically deleted after 30 days
  • AI-generated audio responses (text-to-speech) are created on demand and not permanently stored

Learning Progress

  • Progress data (lesson completions, scores, common errors), achievements and points (XP, badges, leaderboard rankings), and vocabulary tracking (words learned) are retained for the lifetime of your account

Payment Data

  • Payments are processed entirely by Stripe
  • We never store credit card numbers, CVVs, or banking details
  • We store only your Stripe customer ID and subscription status to manage your account

2. How We Use Your Data

  • To provide and personalize the English tutoring service
  • To track your learning progress and adapt lesson difficulty
  • To generate feedback on your writing, speaking, and grammar
  • To manage your subscription and payment status
  • To send you weekly progress reports (if enabled)
  • To maintain leaderboard rankings and achievement systems

3. Third-Party Services

We use the following third-party services to operate the tutor. Only the minimum data necessary is shared with each service:

  • OpenAI — speech-to-text transcription of voice messages
  • OpenRouter — AI language model for conversation and lesson generation
  • ElevenLabs — text-to-speech for listening exercises and voice responses
  • Stripe — payment processing
  • Google — authentication (OAuth sign-in)
  • WhatsApp / Meta — only if you have explicitly opted in via the WhatsApp consent checkbox. We send your phone number to WhatsApp to deliver messages from your teacher. No conversation history is shared with Meta beyond the messages you and the teacher exchange in WhatsApp itself.

We do not share your data with any third party for marketing, advertising, or data brokerage purposes.

5. Your Rights

Right to Deletion

You can permanently delete all your data at any time from Settings → Account inside the app, or by writing to info@spanishnacho.com. Deletion is immediate and irreversible.

Our account deletion page lists the exact steps, everything that gets erased, and the few records we are legally required to keep.

Right to Access

You can see your progress, streak and achievements on your dashboard, and your plan and billing status in Settings → Account. If you want a copy of everything we hold about you, write to info@spanishnacho.com and we will send it.

6. Minimum Age

You must be at least 18 years old to use Inmersy. The course, the AI tutor and the Community are designed for adults. By using the Service, you confirm that you meet this age requirement. We do not knowingly collect data from users under 18. If we become aware that a user is under 18, we will promptly delete their account and data.

7. Data Security

We use industry-standard security measures to protect your data, including encrypted connections (HTTPS), secure credential storage, and access controls. However, no system is 100% secure, and we cannot guarantee absolute security.

8. Changes to This Policy

We may update this Privacy Policy from time to time. Significant changes will be announced inside the app and by email. Continued use of the Service after changes constitutes acceptance of the updated policy.
