Data Storage and Security

We use industry-standard security measures to protect your information. All data is hosted and stored within the United States using the following secure infrastructure:

• Primary Database Storage: Your personal information, account data, conversations, companion profiles, and all user-generated content are stored in CockroachDB Serverless with encryption at rest and in transit
• Vector Storage: AI memory embeddings are stored in Milvus (Zilliz Cloud) with only user IDs as identifiers - no personal information is stored in the vector database
• Cache and Security: Temporary session data and one-time passwords (OTPs) are stored in Redis (Upstash) with automatic expiration (OTPs expire within 10 minutes)
• Media Storage: All photos, images, and media files are privately stored in Google Cloud Storage buckets with restricted access
• Application Hosting: Our backend services run on Hetzner Cloud infrastructure within the United States
• AI Processing: Conversation generation and AI responses are processed using Google Vertex AI
• Analytics and Monitoring: App usage analytics are collected via Mixpanel, and error tracking is handled by Sentry for service reliability

The conversation data used to train your AI companions' memory is processed using Google Vertex AI for natural language understanding. Vector embeddings are generated and stored separately from your personal information, using only anonymized user identifiers for memory retrieval and companion responses.
