How we process your data
Effective as of August 15, 2026
NeuroScan analyzes video and audio recordings of your face and voice to show you emotional and physiological indicators (engagement, stress, confidence, and others). This page explains what data we collect, how and where it is processed, and what rights you have.
Audio recordings (compressed version) from sessions you have recorded — for voice analysis. The video itself is processed locally on your device and is not transmitted to our servers. Individual photos, if you use the identity verification feature ("same person / different person"). Facial biometric templates (vector representations, not photographs) derived from these photos — used for the same verification. Demographic estimates (approximate age, gender) obtained through automated photo analysis — these are statistical estimates, not document-confirmed data. Account data: email, name, password hash (we never store passwords in plain text), profile photo — if you have uploaded one. Technical data: interface language, app version, error diagnostics.
Face, hand, and pose recognition, as well as the calculation of the trust index, stress level, and emotions, occurs LOCALLY on your device in real time during recording — the video itself never leaves the device and is not transmitted to our servers. The final session report is generated on the device based on these local calculations. After recording stops, the following is transmitted to our servers: a compressed audio track — for voice analysis (tone, speech rate, pauses) and for determining who spoke if multiple people participated in the recording; individual photos — if you use the identity verification feature; aggregated text metrics of the session — for generating personalized recommendations and insights.
Speech transcription is performed on our own servers (self-hosted Whisper) — this data is not transmitted to third parties. For certain stages of analysis, we transmit relevant data fragments to external providers: AssemblyAI (speaker identification, if multiple participants are in the recording), Google Cloud Vision (analysis of individual photos during identity verification), as well as LLM providers (OpenAI, Anthropic, Google Gemini, xAI) — for generating text descriptions and recommendations based on already calculated metrics. These services process only the necessary minimum of data to generate an immediate response; each provider has its own privacy policy.
Your audio recordings, photos, and reports are stored on our servers until you delete them manually, or until the auto-cleanup period expires, which you can configure in the "Data Storage" section (disabled by default). Video recordings are stored only on your device and under the control of that device. You can export an archive of your sessions at any time.
You can at any time: view and export your recordings and reports; delete an individual recording or your entire account altogether (Settings → Delete Account) — this permanently deletes all data associated with your account from our servers (audio, reports, biometric templates, photos); video recordings are stored only on your device and are deleted by you locally, like any other files in your phone's gallery; write to us with questions about your data.
All requests to our servers are transmitted over a secure connection (HTTPS/TLS). Access to your recordings and reports is protected by authentication — no one but you can access them. Passwords are stored as irreversible hashes. We apply rate limiting to protect against password guessing.
The app is not intended for individuals under 16 years of age. We deliberately do not collect data from children under this age.
If we materially change how your data is processed, we will notify you within the app before the changes take effect.
For any questions about your data, write to us at support@neuroscanapp.io — we will respond.
