Version 1.4 (beta) · 11 August 2026 · Questions: privacy@montayne.ai
Gabriel Miller-Phillips (sole proprietor), Munich, Germany, reachable at privacy@montayne.ai. A human reads that inbox, and it is the fastest way to reach us about anything in this policy. Montayne is a free invite-only beta run by one person, who does not publish a private home address. A postal business address will be published here when Montayne starts charging for the service. If you need one sooner, for example to exercise your rights in writing, ask at that address and we will give it to you.
Account data. Your email address and first name, from the waitlist or your invite.
Your conversations. When you start a call, the audio of the call is recorded and transcribed. From the transcript, Montayne derives and stores: the things you told it about your life, so future conversations can build on them; your German mistakes and their corrections, so it can track what you struggle with and build practice exercises from your own sentences; session notes and scores that measure how the conversation went, including how the tutor read your mood (Montayne pays attention to how you are feeling so it can respond warmly rather than mechanically); and practice activity and results.
Feedback. Anything you submit through the feedback form, say as an in-call voice note for the team, or answer about pricing.
Technical data. Logs that keep calls working: microphone checks, connection timing, error reports, and usage costs. These are tied to your account but contain no conversation content.
Browser storage. Your login token and app state are kept in your browser's local storage. This is strictly necessary for login. We use no advertising or third-party analytics cookies, and there is nothing to "accept" in a banner.
Audio. We keep no copy of your call audio, but it does pass through our servers, and you should know where it goes. While you are speaking, the audio travels through our own server on its way to the speech-to-text service that produces the live transcript. It exists there only in memory, for the moment it takes to forward it, and is never written to disk. Separately, the recording of the call is stored by our voice infrastructure provider (see the provider list); immediately after each call our systems download it once, produce the accurate transcript, and discard the audio. What we keep from a call is text, never sound.
What talking to Montayne means. Montayne is an AI system, not a human. Its conversation, corrections, and reading of your mood are produced by AI. We tell you this here and before your first call because you have a right to know, and because it is true in every session.
What we never do. We do not sell personal data. We do not advertise. We ourselves never use your conversations to train AI models. Your speech is turned into text on a speech-to-text account of our own, with that provider's model-training programme switched off; this costs us roughly twice the per-minute rate, and we pay it so that your voice is not training material. Our AI providers (Anthropic, OpenAI) do not train on this data under their API terms. Montayne's spoken voice is produced by ElevenLabs through our voice provider Vapi rather than on an account of ours, and we have confirmed what that leg carries: ElevenLabs receives only the German that Montayne itself generates in order to speak it aloud. Your own speech never reaches ElevenLabs.
The one exception, and the trade-off behind it. Vapi Inc. (USA) runs the voice call and stores the call recording. Vapi confirmed to us in writing (July and August 2026) that at our service tier it may use call recordings, transcripts, and call logs to train and improve its AI models. Vapi does offer a mode that switches this off, and we looked at it seriously rather than dismissing it. It works by never storing the recording at all. Montayne re-transcribes the recording of every call the moment the call ends, because the live transcript is not accurate enough on German to correct you from: the corrections you read afterwards, and the personalised practice built from your own sentences, are produced from that second, cleaner transcript. Switching the mode on would remove it. Your corrections would get worse and your practice exercises would stop being generated at all. We decided that a tutor that cannot reliably correct you is not worth shipping, so we have not enabled it, and we would rather show you that trade than leave it out of this page. What limits the exposure: recordings are deleted from Vapi automatically after 14 days, and deleting your account deletes them immediately. If this is not acceptable to you, do not use Montayne, or write to privacy@montayne.ai and we will delete everything.
We use a small number of specialist providers ("processors"). Each receives only what its job requires, and each is bound by a data processing agreement, either one we have concluded with them directly or the one built into the terms we accepted. We are still completing our written file for one of them (Deepgram), and we have asked them for it.
| Provider | Job | What they handle |
|---|---|---|
| Vapi (US), with Daily.co | Runs the voice call, stores the call recording (deleted after 14 days) | Call audio, live transcript, call metadata. May use recordings and transcripts to train and improve its own AI models (see the trade-off explained above) |
| Deepgram (US) | Turns your speech into text live. On our own account, with model training switched off | Your voice during the call, forwarded by our server |
| ElevenLabs (US) | Gives Montayne its voice. Engaged by Vapi on our behalf, not held on an account of ours | Only the German Montayne itself generates. Never your speech |
| OpenAI (US) | Produces the accurate after-call transcript | Call audio, briefly (deleted by them within 30 days) |
| Anthropic (Ireland/US) | The AI that converses, corrects, and summarizes | Transcripts and your learning profile |
| Railway (US) | Hosts our servers and database | Everything we store |
| Resend (US) | Sends our email | Your email address and recap content |
Some providers are in the United States. Transfers are covered by the EU Commission's Standard Contractual Clauses or the EU-U.S. Data Privacy Framework, depending on the provider. For Vapi, the provider that carries the voice call, we have read the data processing agreement that governs our account ourselves: the EU Standard Contractual Clauses apply (module 2, controller to processor), including the UK and Swiss additions. Details on request.
You can, at any time and free of charge: see your data (access) and get a copy (portability); correct it; delete everything, with one email to privacy@montayne.ai, done within 30 days, including the recordings; object to processing based on legitimate interest and withdraw consent (which stops future processing of sensitive content but does not undo the past); and complain to a data protection authority, either your local one or the one responsible for us, the Bavarian Data Protection Authority (Bayerisches Landesamt für Datenschutzaufsicht, Promenade 18, 91522 Ansbach, Germany).
We will ask you to confirm you control the account email before acting on a request.
Montayne is for adults (18+). The beta is invite-only.
We will announce material changes by email before they take effect and keep prior versions available.
