Privacy Policy

Last updated: April 2, 2026 Publisher: CUB-ITH (SIREN: 992 934 448)
⚠️ Entertainment only. Bluffr AI is an entertainment application. Analysis results do not constitute a reliable scientific lie detection diagnosis and should not be used to make real decisions about the truthfulness of a person's statements.

1. Publisher

Bluffr AI is published by CUB-ITH, a French micro-enterprise (SIREN: 992 934 448). For any privacy-related inquiry: contact@cub-ith.fr

2. Data Collected and Processed

Facial analysis data (camera)

Bluffr AI uses your device's front camera to analyze facial expressions in real time using MediaPipe technology (52 expression coefficients, "blendshapes"). These coefficients represent abstract numerical values and cannot be used to identify a person. This data is:

  • Processed locally on your device
  • Transmitted encrypted (HTTPS) to xAI Corp. (Grok) for behavioral analysis, then automatically deleted by xAI within 30 days
  • Never stored by CUB-ITH, never recorded, never used to train AI models

No video or photo is recorded. Only numerical coefficients are processed.

Audio data / transcription

During voice questions, your voice is temporarily recorded on your device, transcribed into text via OpenAI / OpenAI Ireland Ltd (Whisper), then immediately deleted. Only the text transcription is transmitted to xAI. OpenAI automatically deletes API data within 30 days.

Usage data

  • Language preferences (stored locally)
  • Credit balance (stored locally)
  • In-app purchases (managed by Google Play / Apple App Store — CUB-ITH has no access to payment data)

Advertising (AdMob)

In free mode, Bluffr AI uses Google LLC (AdMob) to display advertisements. AdMob may collect: IP address, advertising identifiers, interaction data, diagnostics — subject to your prior consent. See Google Privacy Policy.

3. Sub-processors and International Transfers

  • xAI Corp. / X.AI LLC (San Francisco, CA) — Grok behavioral analysis. Transfer governed by SCCs compliant with GDPR. xAI Privacy Policy
  • OpenAI Ireland Ltd / OpenAI LLC — Whisper audio transcription. Transfer governed by SCCs. OpenAI Privacy Policy
  • Vercel Inc. — API hosting. Certified under EU-US Data Privacy Framework. Vercel Privacy Policy
  • Google LLC (AdMob) — advertising. Certified under EU-US Data Privacy Framework. Google Privacy Policy

No personally identifiable data is transmitted to sub-processors. API data is never used to train AI models.

4. Legal Basis (GDPR)

Data processing is based on your explicit consent (Article 6(1)(a) GDPR), given at first use via a dedicated consent screen. You may withdraw consent at any time by uninstalling the app or revoking camera/microphone access in device settings. For AdMob in EEA/UK/Switzerland, a separate TCF v2 consent is requested at first launch.

5. Automated Decisions

Bluffr AI uses automated processing to generate behavioral analysis results for entertainment purposes only. This processing does not produce legal effects or significant decisions (Article 13(2)(f) GDPR). Results have no scientific or diagnostic value. The app uses a facial expression analysis system based on AI (Article 50, EU AI Act).

6. Data Retention

  • Facial data: no retention by CUB-ITH — immediately deleted after analysis
  • Audio transcription: no retention by CUB-ITH — deleted after transmission to xAI
  • xAI and OpenAI technical logs: automatic deletion within 30 days
  • Preferences and credits: stored locally until uninstallation

7. Your Rights

Under the GDPR, you have the right to: access, rectification, and deletion of your data; withdraw consent at any time; restriction of processing; data portability; and object to automated processing. Since no personally identifiable data is stored by CUB-ITH, exercising these rights primarily means uninstalling the app or revoking camera/microphone access. For any request: contact@cub-ith.fr

8. Security

CUB-ITH implements HTTPS encryption for all communications, maintains no personal data storage, and relies on certified sub-processors (ISO 27001 for OpenAI, SOC 2 for Vercel).

9. Children

Bluffr AI is not intended for children under 12. If you believe your child has used the app, contact us at contact@cub-ith.fr.
