Mimica Privacy Policy

Effective date: July 14, 2026

This Privacy Policy explains how Mimica collects, uses, shares, and protects your information. Please read it carefully.

1. Who we are

Mimica is an AI English pronunciation and conversation tutor. It is available as an Android app and through a web account portal at app.mimica.talk.

Mimica is built and operated by Axielo LLC, based in California, USA. For the purposes of data-protection law, Axielo LLC is the controller of your personal information.

You can reach us at hello@mimica.talk.

2. What we collect

We collect only the data we need to provide the tutoring service:

Email and authentication. When you sign up, we collect your email address and your authentication credentials.
Audio / voice. Your speech recordings captured during tutoring sessions.
Conversation transcripts. The text of your tutoring conversations.
Usage data. Activity metrics such as speaking-seconds, number of turns, and session counts.
Learning data. Your pronunciation error-profile, learning progress, streaks, and CEFR level.
Voice clone (optional). A voice clone you may choose to create. See the on-device section below for how this is handled.

We do not sell your personal data, use it for third-party advertising, or share it with data brokers.

Website analytics. Our public website (mimica.talk) uses Google Analytics to collect aggregate visit statistics (pages viewed, referral source, approximate location).

3. How we use your data

We use the data described above to:

Provide the core tutoring experience — recognizing your speech, assessing your pronunciation, and generating tutor responses.
Track your learning progress, streaks, error-profile, and CEFR level so the tutor can adapt to you.
Maintain your account and authenticate you when you sign in.
Operate, maintain, and improve the functioning of the service.

We do not sell or share your personal information for advertising, and we do not serve ads.

4. Subprocessors — who we share data with

To power the tutor, we send some of your audio and/or text to the following third-party subprocessors, who process it on Axielo's behalf:

A language-model provider — receives your conversation text to generate the tutor's responses.
A speech-to-text provider — receives your audio and returns a transcript, when speech-to-text runs in the cloud rather than on your device (see the on-device section below).
A pronunciation-assessment provider — receives your audio and returns a pronunciation assessment.

Backend infrastructure

A cloud infrastructure provider hosts our backend in the United States: your account and authentication, stored transcripts, usage and learning data, and (only if you enable it) the client-side-encrypted voice-clone backup.

A current list of our subprocessors is available on request at hello@mimica.talk.

Payments

Paid subscription tiers are billed through Google Play Billing, with subscription management handled by a subscription-management processor. Axielo does not collect or store your payment card data directly.

5. On-device posture (and the cloud caveat)

A core part of Mimica's design is keeping as much as possible on your device. We want to state this honestly, including where it does not apply:

Text-to-speech runs fully on-device. The tutor's spoken voice is generated on your phone, with no cloud involved.
Speech-to-text can run on-device. When it cannot run on-device, it falls back to the cloud speech-to-text provider described above.
Your voice clone stays on-device. If you create a voice clone, it is created and stored on your device only, encrypted at rest using the Android Keystore, and is never uploaded. The cloud holds only a reference id, not the clone itself.
Optional clone backup. You may choose to enable a client-side-encrypted backup of your voice clone, which is then stored in Axielo's cloud storage. This is off unless you turn it on.

Important caveat. While your voice clone stays on your device, your conversation audio and text are sent to the cloud subprocessors described above in order to run the tutor. The on-device posture applies to text-to-speech, on-device speech-to-text, and the voice clone — it does not mean your conversations stay entirely on your device.

6. Storage and region

Your account data, transcripts, usage data, learning data, and (if enabled) the encrypted clone backup are stored with our cloud infrastructure provider in the United States.

7. Retention

Chat messages. Raw chat messages auto-expire after a limited period.
Other data. Your remaining data persists until you delete your account.

8. Your privacy rights

GDPR (EU / EEA / UK)

If you are in the European Union, European Economic Area, or United Kingdom, you have rights including the right to access, correct, and delete your personal data. Deletion is self-service (see below).

CCPA / CPRA (California)

If you are a California resident, you have rights including the right to know what personal information we collect and the right to request its deletion. Deletion is self-service (see below).

We do not sell or share your personal information.

9. How to delete your data

You can permanently delete your account and all associated data. There are two ways to do this:

In the app: Settings → Delete account.
On the web: https://app.mimica.talk/delete

Deleting your account purges all of your cloud data, deletes your account, and wipes the voice clone on your device.

10. Children

Mimica is intended for users aged 13 and older. It is not designed for or directed at children, and it includes no features targeted at children.

11. Data security

We protect your data with:

Encryption in transit for data sent between your device and our subprocessors.
Android Keystore encryption at rest for your voice clone on your device.

12. International data transfer

Mimica's backend infrastructure and subprocessors process data in the United States. If you use Mimica from outside the United States, your information will be transferred to and processed in the United States.

13. Changes to this policy

We may update this Privacy Policy from time to time. When we make changes, we will update the effective date at the top of this document.

14. Contact

If you have questions about this Privacy Policy or your data, contact us at hello@mimica.talk.

Governing law: California, USA.
