Dialetica AI (“Dialetica”, “we”, “our”, or “us”) respects your privacy and is committed to protecting your personal data.

## 1. Definitions

For purposes of this Policy:

- **Personal Data**: Any information that can identify an individual (directly or indirectly).
- **Processing**: Any operation performed on data (collection, storage, use, deletion, etc.).
- **Anonymized Data**: Information that cannot reasonably be linked to an identifiable person.
- **Embeddings**: Vectorized numerical representations of text used for technical processing that do not contain human-readable content.

These definitions align with both LGPD (Brazil) and common U.S. privacy standards.

## 2. Information We Collect

Depending on how you use Dialetica AI, we may collect:

### a) Information you provide
- Messages, prompts, and instructions sent to Dialetica AI
- Optional account details (e.g., email, username)
- Feedback or support requests

### b) Automatically collected information
- Device type
- Operating system and browser type
- IP address
- Date/time of access
- Error logs and usage statistics

### c) Context, metadata & embeddings
We may generate and store:
- Session identifiers
- Basic conversation structure (e.g., number of turns, timing, role sequence)
- Performance and routing signals
- Anonymized semantic embeddings

*These data points are processed in a way that prevents reconstruction of original messages and limits any reasonable possibility of user identification.*

---

## 3. How We Use Your Information

Your information may be used strictly for the following purposes:

- To provide and operate the Service
- To maintain session continuity
- To monitor performance, stability, and system integrity
- To prevent fraud, misuse, or abuse
- To generate anonymized signals used in system optimization

**Important clarification regarding AI training:**

Dialetica AI **does NOT use the textual content** of your messages or conversations to train, fine-tune, or retrain any language or generative AI models.

However:

Dialetica AI may use anonymized, non-textual metadata and interaction patterns — such as message length, timing, structural flow, routing decisions, role transitions, and anonymized embeddings — for the sole purpose of improving system performance and orchestration, including predicting which system component (or speaker) should respond next.

This processing:

- Does **not** involve readable message content
- Does **not** train a language model on user text
- Does **not** enable reconstruction of actual conversations
- Does **not** identify individual users

> **Dialetica AI does not sell Personal Data**  
> **Dialetica AI does not use data for advertising purposes**
