DreamWitness-specific data

DreamWitness processes Health Dataas defined by Google Play and special-category data under GDPR Art. 9. This includes sleep data obtained from Android Health Connect and health-related indicators you enter in the dream diary (mood, sleep quality, nightmare classification, emotional state). We process this data only with your explicit consent and solely for the purposes described below.

  • Health Connect sleep data (Health Data): with your explicit permission (android.permission.health.READ_SLEEP), DreamWitness reads sleep session data from Android Health Connect, including: session start and end times, total sleep duration, REM sleep duration, deep sleep duration, light sleep duration, awake count, awake duration, and calculated sleep efficiency. Supported sources: Samsung Health, Google Fit, Oura Ring. This data is cached locally on the device and, for signed-in users, included with dream diary entries synced to Cloud Firestore – to correlate sleep quality with dream patterns and provide Dream Guardian insights.
  • Dream diary entries (includes Health Data): for signed-in users, dream journal entries are persistently stored in the local database and synced to Cloud Firestore. Each entry may include: dream description text, AI analysis results, selected dream symbols, mood/emoji indicator, sleep and wake times, sleep quality rating (1–5), lucid dream indicator, nightmare classification, emotional valence score (−1.0 to 1.0), vividness index (0.0 to 1.0), and attached Health Connect sleep metrics listed above – to maintain the user's dream history and enable pattern analysis.
  • AI-generated dream images: dream descriptions are sent to OpenAI (DALL-E 3) to generate artistic representations of the dream. The resulting image URL is stored with the dream entry – to provide a visual representation.
  • Dream Guardian pattern analysis (includes Health Data): the Dream Guardian feature analyses the user's dream history to detect patterns. The analysis results are stored locally and in Firestore and may include: detected patterns, emotional profile, sleep connection analysis, actionable advice, dream health score (1–100), mood distribution, sleep analysis data, and timing analysis – to provide the user with insights about their dream and sleep patterns over time.
  • Dream content sent to AI: dream descriptions, selected symbols, and conversation context are sent to the OpenAI API for AI analysis. Health-related dream diary data (mood, sleep quality, emotional indicators, Health Connect sleep metrics) is included in Dream Guardian pattern analysis requests via Firebase Functions. OpenAI does not retain data for model training under their contractual terms.
  • Anonymous user identifier: to enforce the free tier limit (2 analyses/week) and Plus status – not linked to a name or email.
  • Purchase data (DreamWitness Plus): transaction token and subscription status – to verify entitlement to Plus features.

Data transfers

Firebase is operated in the nam5region. Where data is transferred outside the EEA, we rely on appropriate safeguards, in particular Standard Contractual Clauses (SCCs) pursuant to Art. 46(2)(c) GDPR. We use PostHog with an EU endpoint. Google Analytics is governed by Google's policies.

Consents and cookies

Analytics cookies on the website (Google Analytics) are loaded only after your consent via a cookie banner. You can withdraw consent anytime in your browser cookie settings; analytics scripts will then not load.

Health Data consent in DreamWitness: the app requests your explicit consent before accessing Health Connect sleep data. You grant this through the Android Health Connect permission dialog. You may revoke this permission at any time in your device's Health Connect settings. Dream diary Health Data (mood, sleep quality, emotional indicators) is voluntarily entered by you; you can stop providing it at any time and can delete existing entries from within the app.
