What the Services store

• Guest use: a random guest identifier and an internal placeholder email keep one person’s activity separate from another’s.
• Optional account: name, email address, and a one-way password hash when you choose to register.
• Learning data: level, lesson progress, answers, vocabulary reviews, pronunciation measurements, assessments, and study streaks.
• Conversations: chat messages, voice transcripts, and only the facts you explicitly ask the active companion to remember.
• Bug reports: the description and reply email you choose to provide, plus the current page, device/browser, screen size, language, and timezone. Chat history and audio are not attached.
• Payments: provider payment ID, product, amount, currency, status, and access period. Mila does not receive or store full card details.

Voice data

Pronunciation tools and the private level-assessment path send a recording to Mila only after you tap the microphone. Its speech service uses it to create a transcript, then deletes the recording after the request. The transcript and resulting learning feedback may remain in your learning history.

The Mila level assessment offers a private server voice path, a written path with no microphone, and a separate optional Live conversation. Before Live conversation starts, the Service explains that microphone audio and its transcript will be sent to OpenAI for real-time processing and asks for explicit consent. Nothing is sent to OpenAI from that path unless you agree.

Gia’s companion voice room currently offers only consented Live voice to eligible preview or Pro accounts; its unfinished private/local mode is unavailable. Before Live starts, Gia explains that microphone audio and the transcript will be sent to OpenAI for real-time processing and asks for explicit consent. If you do not agree, you can continue in text chat. Gia asks separately for each page session.

Mia Talk is an optional anonymous live conversation. Before it starts, Mia explains that microphone audio and its transcript will be sent to OpenAI for real-time processing and asks for explicit consent. Mia does not save the audio, transcript, or conversation history. Audio is never sent to advertising companies.

Text chat may be processed by a configured AI model provider to generate a reply. The Services’ server brokers those requests; clients do not receive provider credentials.

Why data is used

The Services use this data only to operate: authenticate users, verify email and recover accounts, personalize lessons and conversations, measure learning progress, transcribe requested recordings, generate replies, process and reconcile a requested payment, prevent abuse, deliver requested bug reports to the owner, and diagnose technical failures.

When direct bug-report delivery is enabled, the email delivery and mailbox providers process the report only to deliver and store that support email.

No advertising or tracking

The Services do not sell personal data, show behavioral advertising, or combine your activity with third-party data for advertising. The iOS app contains no advertising or cross-app tracking SDK.

Retention and deletion

Learning and account data is retained while your guest profile or account remains active. Mila’s Account page can delete the shared account and its learning data. Gia’s Account page can independently delete Gia conversation history and remembered facts without touching Mila learning data. These actions cannot be undone.

When an account has a payment, Mila may retain a detached record of the payment ID, amount, currency, status, and access period where required for accounting, fraud prevention, refunds, or legal compliance. The local record no longer has a direct relation to the deleted learning profile, but it can remain linkable through processor records where required. YooKassa and other service providers may retain data under their own legal obligations.

Security and contact

The Services use encrypted HTTPS connections and send speech and model requests through their server. Hosted checkout opens YooKassa directly so the Services never handle card credentials. Resend processes the email address only when verification or recovery mail is sent. No internet service can promise perfect security, so please do not submit passwords, banking details, or other secrets in chat.
