All data is encrypted with AES-256-GCM, and you retain full control over caller data, ensuring compliance with legal privacy standards.
How long does it take to set up Answrr for a law firm?
Answrr can be set up in under 10 minutes thanks to its AI onboarding assistant. This intelligent assistant interviews you about your practice, services, hours, and call handling preferences, then automatically configures your agent.

You have full control over data retention and deletion, and you can delete any caller memory at any time. While Answrr is not currently HIPAA-certified, its security architecture meets the standards used by healthcare and legal organizations. For firms requiring HIPAA compliance, we recommend consulting with your legal team and using Answrr in a non-HIPAA environment or with appropriate safeguards.

For example, if a caller says, 'I need to speak to a criminal defense attorney,' the AI will transfer the call to your team with full context—previous conversation history, case type, and concerns mentioned. This ensures no information is lost, and your team can pick up the conversation seamlessly, saving time and improving client experience.
What happens to my client’s data after a call?
After each call, Answrr generates a full transcript, AI summary, sentiment analysis, and structured data (e.g., name, case type, follow-up needed). These are securely stored and delivered to you via email or webhook. You can access them in the dashboard, export them, or delete them at any time. All data is encrypted at rest and in transit. You own your data—Answrr never sells or shares it. You can also delete any caller memory to comply with privacy regulations like GDPR.
