1. Introduction

- Technical Data: IP address, device information, browser type, operating system, and related diagnostics.
- Usage Data: information about how you use our website, products, and services.
3. How We Use Your Data

4. Third-Party Sharing and Disclosure
We do not sell or rent your personal data. We disclose personal data to third parties only as needed to provide the Service, complete transactions, protect the Service, or comply with law.
- Payment processors: To complete a purchase, we may provide Waffo and other payment processors with your account email where available, a customer or order reference, the product or plan purchased, the applicable price and currency, and transaction metadata needed to process the payment, prevent fraud, and reconcile the order. Payment card credentials and any billing details requested at checkout are collected and processed directly by the payment processor under its own privacy terms; Ancient Echoes receives transaction identifiers and payment status, not your full payment card number.

This data is shared only to provide the requested AI output. We do not send your account password or payment card credentials to AI model providers.

- Some providers may process data in countries or regions where they operate. Their processing is also governed by their own privacy terms and contractual safeguards where applicable.
5. Data Security
We implement reasonable technical and organizational safeguards designed to protect personal data against unauthorized access, alteration, disclosure, misuse, or loss.
6. Data Retention
We retain personal data only for as long as reasonably necessary to provide the Service, meet legal or accounting obligations, resolve disputes, and enforce our agreements.
