What happens to your words

What we keep

• Your email address, your name and goals if you add them, your time zone, your settings (language, level, age group, weekly goal, reminder hour) and when you last used the app.
• Transcripts of your practice conversations and warm-ups, the coach's feedback, your Try Again attempts and your own confidence ratings.
• Phrases you save, which lessons you completed, and situations you described for free practice.
• Usage counts (how many replies, how many seconds of audio, how long each answer took) for cost tracking and limits. Never the words.
• For each recording: what speech-to-text heard, how long it took, how sure it was of each word, and measurements of the sound (pace, pauses, loudness, pitch variety, how long you waited before speaking). The measurements are shown to you as delivery estimates; the rest is so transcription mistakes can be found.
• Notes you leave on a conversation about what felt off.
• Numbers worked out by the app from each conversation: the level you practiced at, how long your answers were, how often you said you didn't understand or answered in English, how often you tapped Translate. They suggest a level change and show the author which conversations are too hard for everyone. They are computed by code; nobody reads your words for them.
• A few things you said about yourself (hobbies, plans, favorites), each with the words you said, so your topic-chat friend can follow up; and the language points you keep working on. Never your school, address, contact details or private matters. See and delete them in Settings. Plus the real-world missions suggested to you and whether you marked them done.
• If you turn on the daily reminder: the hour you picked and your phone's push address (from Apple, Google or Mozilla), so one reminder a day can reach it. A reminder may mention one thing you told your practice friend; its text is encrypted so the push service cannot read it. Turning it off deletes the address.
• For 13 to 17 accounts: a parent named by the family can see, for each teen, the days and minutes practiced this week, the practice language, lessons done, level, the last day practiced and how many missions are open or done. Never what you said: transcripts, feedback, memory notes and recordings are only yours, and the author's review tools read only the author's own account.
• Your voice choices, and any voice you copied in Settings > Voices: its 10-40 second sample and the consent line you ticked. Samples and copied voices exist on this computer only; voices are made here, not by an outside service.

What we don't keep

• Audio. Recordings are transcribed and discarded. Nothing you say is stored as sound.
• Passwords. Sign-in is by a code sent to your email.
• Voice messages you record for family. The app turns one into text and, only if you ask, has the AI provider check that text; then it forgets both the text and the sound. You send the message yourself.
• Analytics that contain transcripts or audio.

Who processes your words

• Speech-to-text: on the personal version, a program running on the author's own computer (no audio leaves it). On a hosted version, a speech-recognition provider (currently OpenAI) receives the audio and returns text.
• Conversation partner and coach: an AI provider (currently Anthropic) receives the scenario, the transcript of the conversation, your goals and level, the memory notes your practice friend may follow up on, the points you keep working on, situations you describe for free practice, and a voice message's text when you ask for it to be checked. Your first name if you added one (so the partner can call you by it); never your email. It returns the partner's lines, the feedback and the comparison.
• Voices: the partner's lines are spoken by a program on this computer, or by your browser's built-in speech. Copied voices are made on this computer too; no voice sample goes to an outside service.
• Email: an email delivery provider (currently Resend) sends your sign-in codes.
• Hosting and database: a hosting provider and a database provider store the data listed above.

Don't share confidential employer, client, financial or medical information while practicing. The app reminds you of this before each conversation.

Deleting

• Any conversation can be deleted from its page in History. The transcript, feedback and its recordings go with it, immediately. Memory notes and missions taken from it stay until you delete them in Settings. Warm-up and “say it again” recordings belong to no conversation; they go with your account.
• Your whole account can be deleted in Settings. Everything above is removed immediately. Sign-in codes and the email delivery log, which hold only your address, expire on their own.

Honesty

The coach only comments on your words. It never claims to hear your pronunciation, pace or confidence, because a transcript cannot show them. Every quote in the feedback is checked against your transcript in code; a quote that isn't there is dropped. Scores are rough estimates, not measurements.
