Privacy Policy

Mentivox is operated by Mentivox Ltd, a company incorporated in England and Wales. We provide an AI-powered companion application designed to support emotional wellbeing. Our registered address and contact details are available by emailing support@mentivox.com.

We collect only what is necessary to provide the service:

• Account information: email address, first name, and last name provided at registration.
• Conversation content: messages you send to Mentivox, stored to provide continuity across sessions.
• Preferences: theme and notification settings stored on your device.
• Technical data: anonymised usage signals used to monitor service health (no personally identifying information).

We do not collect payment information, precise location, or device sensor data.

• To deliver and personalise the companion experience.
• To maintain conversation continuity across sessions.
• To send proactive check-in messages you have opted into.
• To detect and respond to abuse or misuse of the service.
• To comply with our legal obligations.

We do not sell your data. We do not use your conversation content for advertising.

For users in the United Kingdom and European Economic Area, our legal bases for processing personal data are:

• Contract: to provide the service you have signed up for.
• Legitimate interests: to improve service reliability and prevent misuse.
• Consent: for optional communications such as proactive check-in notifications.

• AES-256 encryption for all data at rest.
• TLS encryption for all data in transit.
• Access controls limiting which staff can access user data.
• On-device processing for sensitive inputs where technically possible.

We retain your account data for as long as your account is active. Conversation history is retained to provide continuity of care. You may request deletion at any time; see Section 8 for your rights.

We use a limited number of third-party providers to operate the service, including cloud infrastructure and AI model providers. All providers are bound by data processing agreements and are prohibited from using your data for their own purposes.

We do not share conversation content with third parties for any commercial purpose.

Under UK GDPR and the Data Protection Act 2018, you have the right to:

• Access the personal data we hold about you.
• Request correction of inaccurate data.
• Request deletion of your data (“right to be forgotten”).
• Object to or restrict processing.
• Data portability.
• Withdraw consent at any time (where processing is based on consent).

To exercise any of these rights, email support@mentivox.com. We will respond within 30 days.

Mentivox uses only functional cookies and local storage necessary to operate the service (session management, theme preferences). We do not use advertising cookies or third-party tracking cookies.
