B. Personal Data We Collect Automatically

Log Data

We collect information your device sends when using the Services, such as:

• IP address,
• Timestamps,
• Browser type/settings,

Such as:

Location Information

We may infer your general location (e.g., city/region) from IP address for security and experience personalization. If you enable location features, we may collect more precise location (e.g., GPS), depending on your device permissions.

Cookies and Similar Technologies

We use cookies and similar technologies to:

• Keep you signed in,
• Remember preferences,
• Measure performance and usage,
• Improve reliability and security.

C. Information From Other Sources

We may receive information from:

• Payment processors (e.g., payment confirmation and fraud signals),
• Analytics and security providers (fraud/abuse prevention),
• App stores (if you install via Apple/Google),
• Identity/auth providers (if you sign in via OAuth).

3. How We Use Personal Data

We use personal data to:

Provide and Operate the Services

• Create and manage accounts,
• Process payments,
• Deliver routing and AI responses,
• Store conversation history,
• Enable file upload and retrieval features.

Route Requests and Generate Responses

Darius may process your Input and send it to:

• Internal systems that pre-process/route requests, and/or
• Third-party AI providers to generate Output.

Improve and Develop Darius

• Debug issues and improve reliability,
• Evaluate performance,
• Develop new features.

Safety, Security, and Abuse Prevention

• Detect fraud, abuse, spam, and misuse,
• Enforce Terms of Use,

Communicate With You

• Service updates,
• Security alerts,

• Product announcements (where permitted by law; you can opt out of marketing).

Legal Compliance

• Comply with applicable laws,
• Respond to lawful requests,
• Protect rights, safety, and property.

De-identified / Aggregated Data

We may anonymize or aggregate data and use it for analytics and service improvement. We do not attempt to re-identify de-identified data unless required by law.

4. AI Training and Model Improvement Choices

Because Darius may route your content to third-party AI models, those providers may process your content under their own terms.

Separately, Tranquil may use certain Content to improve Darius (for example: to improve routing, safety filters, and overall performance), subject to your settings.

Where available, you may be able to:

• Disable use of your conversations for internal improvement,
• Delete conversations and account data,
• Use “temporary” or “incognito” modes (if enabled in the product).

5. How We Share Personal Data

We may share personal data in the following circumstances:

We share data with vendors who help us operate Darius, such as:

• Cloud hosting and storage,
• Content delivery networks,

• Customer support tools,
• Email delivery services,
• Payment processors,
• Security and fraud prevention providers.

They process personal data only to perform services for us, under contractual confidentiality and security obligations.

B. Third-Party AI Providers (Core to Darius)

When you use Darius, your Input (and sometimes recent conversation context) may be sent to third-party AI providers to generate Output. These providers may process your data under their own privacy policies and terms.

C. Business Transfers

If we are involved in a merger, acquisition, financing, bankruptcy, or sale of assets, personal data may be transferred as part of that transaction.

6. Retention

We retain personal data only as long as necessary to:

• Provide the Services,
• Comply with legal obligations,
• Resolve disputes,

Retention depends on:

• The type of data,

You may be able to delete your account and/or conversation history by contacting support. Some data may be retained longer for security, fraud prevention, or legal compliance.

Note on AI Outputs and Corrections

AI-generated outputs may include inaccuracies. If you believe Darius has produced output containing personal data about you that you want corrected or removed, contact us and we will review the request subject to applicable law and technical feasibility.

8. International Data Transfers

We may process and store personal data in multiple countries where we or our service providers operate. When transferring personal data internationally (including from the EEA/UK/Switzerland), we use legally recognized transfer mechanisms where required (e.g., Standard Contractual Clauses).

10. Security

We implement reasonable technical and organizational measures designed to protect personal data. However, no system is 100% secure. You are responsible for keeping your credentials confidential and using the Services responsibly.

11. Additional U.S. State Disclosures (If Applicable)

We do not sell personal data. We do not share personal data for cross-context behavioral advertising in a way that would be considered “selling” under applicable U.S. state privacy laws.

12. Changes to This Policy

We may update this Privacy Policy from time to time. We will post the updated version and effective date. Where required, we will provide additional notice.
