Privacy policy

What we collect

• Account data: name, email, English level, interests, profession, and native language.
• Conversation data (only with your consent): your session transcripts, corrections, saved vocabulary, practice time, and your Spanish/English ratio.
• Payment data: processed securely by Stripe. We never see or store your card number.
• Basic technical data: the minimum device info needed for the app to work.

Your voice

When you talk with Coral, your audio is processed in real time to turn speech into text, generate the response, and play Coral's voice back.

By default we do not store your audio to train models. Training on your voice is a separate option that stays off unless you explicitly turn it on.

How we use your data

• Personalize your lessons — Coral remembers your progress and adapts to your level.
• Generate your Coral Notes, vocabulary, and progress tracking.
• Improve the product (always with your knowledge).
• Process your payment and provide support.

We don't sell your data and we don't use it for advertising.

Who we share it with

We share the minimum necessary with the providers that make Coral work. Each one only processes what its function requires:

• Supabase — database and user accounts.
• Railway — hosting for our server.
• xAI (Grok) — the AI model that talks with you.
• Groq — speech-to-text.
• ElevenLabs — text-to-speech.
• Stripe — payment processing.

Your consent and control

When you start, we ask permission to store your conversations so Coral can remember your progress. You decide, and you can change your mind:

• Delete your conversation history anytime from your Profile.
• Request access, correction, or deletion of your data by emailing [email protected].

How long we keep it

We keep your data while your account is active. When you delete your history or your account, we remove the corresponding data.

Security

We encrypt data in transit (HTTPS) and work with providers that meet recognized security standards. No system is 100% foolproof, but we handle your information with care.

Minors

Coral is intended for adults, or minors under the supervision of a responsible adult. It is not directed at children under 13.

Changes to this policy

We may update this policy. If we make material changes, we'll let you know in the app or by email.
