This policy describes how Mitra AI (“Mitra AI”, “we”, “us”) collects, uses, and protects information when you use our WhatsApp companion for spoken English practice (the “Service”).
This is the official privacy policy for Mitra AI. Mitra AI is operated by VoiceEval Technologies Private Limited.
We work directly with individual learners across India. The Service is delivered through WhatsApp: you send a voice note, and we reply with simple feedback on grammar, vocabulary, fluency, clarity, and pronunciation.
Information we collect
Information you provide
- Contact details — the WhatsApp phone number you message us from, and any name you choose to share with us.
- Voice recordings — the audio you send while practising spoken English.
- Text messages — replies you send during onboarding and practice sessions, such as picking a topic, choosing a feedback language, or requesting another attempt.
- Profile information — your learning goal, comfort level, preferred feedback language, and similar preferences, if you choose to share them.
Information generated by the Service
- Transcripts — written transcriptions of your voice recordings.
- Feedback — spoken-English feedback covering grammar, vocabulary, fluency, clarity, and pronunciation, along with corrected examples and model pronunciation samples.
- Usage data — timestamps, attempt counts, and progress signals that help us improve the Service.
Information from WhatsApp
We receive messages and message metadata through the WhatsApp Business Platform operated by Meta. Your use of WhatsApp is governed by Meta’s own Privacy Policy.
How we use information
- To run the practice session: transcribe your audio, generate feedback, and reply on WhatsApp in your preferred language.
- To improve the quality of feedback and pronunciation samples.
- To develop, train, and evaluate speech and language models — our own, and those of partners we licence data to. See Voice data, AI development and licensing below.
- To send service messages on WhatsApp, such as practice prompts, feedback, progress updates, and support replies related to your learning activity.
- To respond to enquiries and provide support.
- To comply with applicable law.
How we share information
We share information in the following circumstances:
- Service providers — trusted vendors that help us run the Service, including cloud hosting, speech recognition, text-to-speech, automated language analysis, and analytics. They process data only on our instructions and under contractual confidentiality.
- WhatsApp / Meta — messages necessarily transit Meta’s WhatsApp Business Platform.
- Legal compliance — if required by a valid legal process, or to protect the rights, safety, and property of users or the public.
- Data licensing partners — organisations we licence voice recordings, transcripts, and the assessments generated from them to, for developing, training, and evaluating speech and language technology, under written agreements that restrict how the data may be used and prohibit onward transfer. See below.
We do not share your recordings or transcripts for advertising, and we do not sell your contact details. We may be paid when we licence voice data as described below.
Voice data, AI development and licensing
Recordings of real speakers are what make speech technology work well for Indian voices — including the technology this Service itself runs on. We use the recordings you send, their transcripts, and the automated assessments generated from them to develop and evaluate speech and language models, and we may licence that data to other organisations that build such models.
Where we do this:
- We remove direct identifiers, such as your phone number, before data leaves our systems.
- Recipients are bound by written agreements that limit use to model development and evaluation, prohibit any attempt to re-identify you, and prohibit passing the data on.
- We never licence your name, phone number, or payment information.
- A recording is still your voice. We cannot promise a voice is unidentifiable the way a removed phone number is, and we would rather say so plainly than imply otherwise.
You can opt out at any time. Reply “no data” on WhatsApp, or write to hello@voiceeval.com. Opting out keeps your recordings out of any future licensing. It does not change your practice sessions or feedback in any way — you can keep using the Service exactly as before. Data already provided to a partner before you opt out cannot be recalled.
WhatsApp communication choices
If you message Mitra AI on WhatsApp, we may reply on WhatsApp with practice prompts, feedback, progress updates, and support messages related to the Service. You can ask us to stop sending messages by replying “stop” on WhatsApp at any time.
Data retention
Voice recordings, transcripts, and feedback are retained for as long as your account is active, plus a reasonable period thereafter to support your learning journey (typically up to 12 months from your last activity). Aggregated, de-identified analytics may be retained longer. On written request, we will delete identifiable practice data within 30 days, subject to any legal retention obligations.
Security
We use industry-standard safeguards including encryption in transit (TLS), encryption at rest for stored recordings and transcripts, access controls, and audit logging. No system is perfectly secure; we will notify affected users and authorities of a data breach as required by applicable law.
Your rights
Depending on where you live, you may have rights to access, correct, or delete your personal information, to withdraw consent, or to lodge a complaint with a supervisory authority. Indian users may exercise rights available under the Digital Personal Data Protection Act, 2023.
To exercise any of these rights, message us on WhatsApp at +91 63614 05165. We will respond within 30 days.
Minors
The Service is intended for adults. If you are under 18, please use the Service only with the consent of a parent or guardian. Parents and guardians may contact us at any time to review or delete their child’s practice data.
International transfers
We are based in India. Some service providers we use may process data outside India. Where this happens, we put in place contractual safeguards consistent with applicable law to protect your information.
Changes to this policy
We may update this policy from time to time. Material changes will be communicated to active users where reasonably possible.
