Overview

Entwine is a private two-person chat space with an AI mediator, built for couples and close partners working through difficult conversations. Your privacy is fundamental to the trust this app requires. This Privacy Policy explains what data Entwine collects, how it is used, and the safeguards in place to protect your information.

🔐 Privacy Guarantee: Each room is limited to exactly two people. No one else can access your conversations.

AI Processing

PII Stripping

Before conversation data is sent to the AI model for processing:

Model Improvement

Anonymized conversation data (with all PII removed) may be used to improve and fine-tune the AI mediator model. This data contains no personally identifiable information and cannot be traced back to you or your partner.
