title: Compliance in Arc applications
---

Chronicle compliance — PII encryption, key-based erasure, and automatic decryption — works transparently when you use Arc read models and queries. No additional configuration is required: the same encryption and decryption behavior described in [Read models and PII](/chronicle/compliance/read-models/) applies whether you access read models directly or through Arc's generated command and query proxies.

For detailed guidance on using compliance features from an Arc application, see `Arc.Chronicle.Compliance`.
