Last updated: April 16, 2026

What We Collect

Encryption & Data Retention

We take the security of your data seriously:

• Message encryption: All message content is encrypted using AES-256-GCM encryption at rest. Even in the event of a database breach, your message content cannot be read without the encryption key.
• PII encryption: Names, email addresses, and behavioral profiles are encrypted at rest using the same AES-256-GCM standard.
• Media deletion: Photos and screenshots sent via MMS are deleted from Twilio's servers when the associated message expires. Media URLs stored in our database are encrypted.
• Message retention: Message content is automatically and permanently deleted after 30 days. Request summaries (brief, non-sensitive descriptions) are retained for the duration of your subscription.
• Account deletion: You can request complete deletion of all your data at any time. This removes all messages, requests, member profiles, devices, and family data permanently.

What We Don't Do

• We never sell your data to anyone
• We never use your conversations to train AI models
• We never share your information outside your family group
• We never store your payment card details
