Terms and conditions
Last Updated: January 06, 2026
1. Data Collection and Local Processing
Unlike traditional apps, Emotion Stamp operates as a Sensor Hub. Most data is processed and stored exclusively on your iPhone’s local memory using SwiftData and a Local Vector Database.
Journal Entries & Voice Notes: Text notes and voice recordings are stored only on your device. Voice-to-text transcription is performed on-device using Apple’s Speech framework.
Biometric Data (HealthKit): If granted permission, we pull Heart Rate (BPM) and Heart Rate Variability (HRV) from Apple Health. This data is used to provide physiological context to your stamps and stays on your device.
Location & Environment (WeatherKit/CoreLocation): We capture hyperlocal context (e.g., "Work," "Home," or current weather conditions) at the moment of a stamp. This data is processed locally to identify environmental triggers.
Local Entity Scrubbing: Before any data is utilized for AI reflections, our Natural Language Framework automatically removes Personal Identifiable Information (PII) like names or addresses on-device.
2. Artificial Intelligence and Data Transmission
To provide "Gentle Reflections," the App utilizes xAI’s Grok model. We use a "Super-Prompt" architecture designed to protect your identity:
Anonymized Packets: We send only scrubbed, anonymized data packets to the Grok API. This includes mood values, timestamps, and the "scrubbed" context (e.g., "User is [Angry] at [Person] while at [Work]").
No Training: We do not allow third-party AI models to train on your data. Your inputs are used solely to generate a one-time reflection.
Local Memory: We use VecturaKit to manage "Semantic Retrieval" locally. The AI only receives the most relevant context needed for a specific reflection, rather than your entire history.
3. Third-Party Services & Analytics
No Tracking: We do not use third-party analytics (like Google Analytics or Firebase) or advertising trackers.
Apple StoreKit: All premium subscriptions ("Reflections+") are processed via Apple’s encrypted in-app purchase system. We do not have access to your credit card or billing details.
Offline Functionality: Because our engine is "Local-First," your history and charts remain accessible without an internet connection. Only AI reflections require a network request.
4. Data Retention and Deletion
User Control: You have full control over your data. You can delete individual entries or your entire history directly within the History View.
App Deletion: Deleting the App from your iPhone will permanently remove all locally stored data, as we do not maintain cloud backups of your personal journals.
5. Australian Privacy Principles (APP) Compliance
As an Australian-built app, we comply with the Privacy Act 1988 (Cth).
Transparency: We are clear about what we collect and why.
Access: You have total access to your data at all times via the App interface.
Security: We leverage Apple’s native encryption and on-device processing to ensure your data is as secure as the device itself.
6. Not a Medical Device
Emotion Stamp is a wellness tool, not a clinical or diagnostic app.
Observational Only: AI reflections are generated using observational heuristics and are not medical advice.
Emergency Situations: If you are experiencing a mental health crisis, please contact professional services immediately (e.g., Lifeline at 13 11 14 in Australia).
7. Changes to This Policy
We may update this policy to reflect changes in our "Engine" architecture or legal requirements. Any updates will be posted within the App settings.
Contact Us: For questions regarding your privacy, please contact our support team through the link in the App's SettingsView.
