What happens to your data?

Your data is used to provide the AI companion service and improve its performance through anonymized training. While your conversations are processed by third-party AI providers to generate responses, they are contractually prohibited from using your data for their own model training.

Does it train on your data?

The policy states that anonymized data is used to train proprietary safety algorithms and enhance chatbot performance, but explicitly notes that anonymized data is not used to train third-party large language models or other AI systems.

Can you opt out?

Yes. You can opt out of marketing emails via unsubscribe links, and you can opt out of targeted advertising/data sharing via the cookie settings or by contacting the company.

Data retention

Profile information and messages are retained for up to 60 days after contract termination. Financial records and account information are retained for 10 years. Data for legitimate interest analysis is retained for up to 1 year.

Encryption & security

All transmitted data is encrypted using standard Secure Socket Layer (SSL) encryption. Stored data is maintained on secure servers protected by firewalls, role-based access controls, and passwords.

Is it safe for work?

Not recommended. The service is designed as a personal AI companion and explicitly discourages the sharing of sensitive information, which may be inappropriate for professional or enterprise environments.
