Yes. Your journal entries, mood stamps, notes, and voice recordings are stored locally on your device using SwiftData. Voice transcription and PII (personally identifiable information) scrubbing happen on-device before any data leaves your phone.

Emotion Stamp is primarily local-first — your journal, history, and biometric context all live on your device. However, when you stamp a mood and request an AI reflection, an anonymised, scrubbed data packet is securely sent to our AI model via Firebase. Firebase is used to securely store and call the API key at the moment of stamping — your raw personal content is never stored on external servers beyond what is needed to generate your reflection.

Only anonymised, PII-scrubbed context packets are transmitted — this includes your mood value, timestamp, and scrubbed environmental context (e.g. weather, general location). Your actual journal text, names, and personal details are stripped on-device before transmission. Firebase is used purely as a secure key vault and relay — it does not store your personal journal data.

Never. We do not sell, share, or use your data for advertising. We do not use third-party analytics trackers. Your data is yours.

All locally stored data — stamps, journal entries, voice notes, history — is permanently deleted when you remove the app. We do not maintain cloud backups of your personal journals.

When you stamp a mood, Emotion Stamp builds an anonymised context packet on-device (your mood, biometric snapshot, scrubbed notes, and relevant past stamps). This packet is securely sent to our AI model via Firebase. The AI generates a personalised reflection based on your chosen tone — Gentle, Gen Z, Stoic, Motivational, or Group Chat.

Emotion Stamp uses xAI's Grok model to generate reflections. All transmissions use an anonymised "super-prompt" architecture designed to protect your identity.

No. AI reflections are generated in real-time and saved locally on your device as part of your stamp record. They are not stored on our servers.

Yes — your history, charts, and past stamps are fully accessible offline. AI reflections require an internet connection as they involve a secure call to the Grok API via Firebase.

No. All AI-generated reflections are observational and for personal journaling purposes only. Emotion Stamp is not a clinical tool and does not provide medical or psychological diagnosis. Please see a qualified professional if you need mental health support.

Reflections+ unlocks Voice Journaling, unlimited AI reflections, advanced AI personas, and premium features as they are released. Free users receive a limited number of AI reflections per day.

Emotion Stamp reads biometric data from Apple Health. Go to iPhone Settings → Health → Data Access & Devices → Emotion Stamp and ensure Heart Rate and Heart Rate Variability are toggled on. You also need at least one recent Health reading for the data to appear.

Go to iPhone Settings → Emotion Stamp → Location and set it to 'While Using'. Also ensure Location Services are enabled globally in Settings → Privacy & Security → Location Services.
