We use the information we collect for the following purposes, matched to the data categories described in Section 2:
Service delivery. We use your account data, conversation data, and onboarding information to operate the Spiral platform—delivering AI companion responses, maintaining your conversation history, matching you to a Care Blueprint based on your profile, and enforcing subscription limits.
Personalization. After each AI interaction, Spiral performs an automated process called “memory extraction.” A separate AI call analyzes the conversation and extracts key facts, patterns, and themes about you (for example, your typical stressors, coping strategies, or stated preferences). These extracted facts are stored as “patient memory” and incorporated into future AI responses to create continuity across sessions.
AI and ML processing. We are transparent about how your data interacts with AI systems:
- Your messages are sent to Anthropic, Inc.’s API (Claude Haiku model) for the generation of AI responses. Anthropic processes these messages as a data processor on our behalf. Please refer to Anthropic’s privacy policy for information about their data handling practices.
- Your text is converted into mathematical vector representations called “embeddings” for the purpose of matching your profile to the most suitable Care Blueprint. This embedding process is performed entirely on our own infrastructure hosted on Railway. We never send your text to third-party embedding services such as OpenAI.
- Each AI response is assembled using a structured three-layer context: (1) a hardcoded system prompt that frames Spiral as a wellness tool for healthcare workers; (2) the matched Care Blueprint and any Therapist preference settings; (3) extracted patient memory facts and recent conversation history; and (4) your new message. No other information about you is included.
Safety. Every inbound message is scanned for indicators of suicidal ideation, self-harm, or imminent danger. If such indicators are detected, Spiral immediately surfaces crisis resources including the 988 Suicide & Crisis Lifeline, the Crisis Text Line (text HOME to 741741), and 911. In cases of apparent imminent danger, we may be required by law to disclose information to emergency services.
Service improvement. We use de-identified and aggregated analytics to understand how the Services are used, identify technical issues, and improve our product. Personal information is not used to train AI models without separate disclosure and consent.
Communications. We use your phone number to deliver SMS messages as part of the core service. We use your email address to send account notifications, billing confirmations, and security alerts. We do not send marketing emails without your explicit opt-in.
Billing and quota enforcement. We use your subscription status (received from Stripe) to enforce message quotas and gate access to premium features. Messages sent when you are over quota are responded to with an upgrade notice and do not count against your usage.
Legal compliance. We may process your information as necessary to comply with applicable laws, respond to lawful requests from government authorities, enforce our Terms of Service, or protect the rights and safety of Spiral, our users, and the public.
