Privacy Policy

1. Who We Are

AI Model Comparator is operated by the team behind app.423pm.com. For data-protection purposes, we are the data controller of personal information collected through the Service. Contact details are provided in Section 12.

2. Information We Collect

2.1 Information You Provide Directly

2.2 Information Collected Automatically

When you use the Service we automatically collect: IP address; browser type and version; operating system; referring URL; pages visited and time spent; session identifiers; feature-usage events (e.g., models selected, export format used); and performance metrics (response times, token counts, error rates). This data is used to operate, secure, and improve the Service.

2.3 Cookies and Similar Technologies

We use the following types of cookies and local-storage tokens:

3. How We Use Your Information

We process your information on the following legal bases and for the following purposes:

4. Anonymised Research and Aggregate Insights

We believe that understanding how AI models perform across diverse real-world prompts benefits the broader AI research community and helps us build a better product. To support this, we may analyse anonymised, de-identified versions of prompts and their corresponding AI model responses.

What "anonymised" means in practice: Before any prompt is used for research purposes, we apply a multi-step de-identification process that removes or generalises all direct identifiers (name, email, account ID) and indirect identifiers (IP address, precise timestamps, rare combinations of attributes) that could reasonably be used to re-identify you. The resulting data is stored separately from your account records.

What we do with it: We use anonymised data to: (a) measure and publish aggregate model-performance benchmarks; (b) train internal quality-scoring algorithms; (c) produce marketing materials illustrating the Service's capabilities; and (d) conduct or contribute to academic research on LLM evaluation. Any published findings present only aggregate statistics — individual prompts are never attributed to a specific user.

What we will never do: We will never attempt to re-identify anonymised data, sell it, or share it with third parties in a form that could identify you.

Opt-out: If you prefer that your prompts are excluded from research use entirely, you can toggle this off in Settings → Privacy. This setting takes effect immediately for future queries; previously anonymised data cannot be retroactively removed from aggregate datasets.

5. How We Share Your Information

5.1 Third-Party AI Model Providers

When you submit a prompt, it is transmitted to the AI providers you select (e.g., OpenAI, Anthropic, Google, xAI) using either your own API key or our system key. Each provider receives the prompt text and processes it under their own privacy policy. We recommend reviewing the relevant provider policies before submitting sensitive information.

5.2 Service Providers (Sub-processors)

We engage trusted sub-processors to help us operate the Service. Each is bound by contractual data-processing agreements that restrict them to processing your data only on our instructions and prohibit them from using it for their own purposes.

5.3 Legal Disclosures

We may disclose your information if required by law, court order, or valid government request, or if we believe in good faith that disclosure is necessary to: (a) comply with a legal obligation; (b) protect the rights, property, or safety of AI Model Comparator, our users, or the public; or (c) detect, prevent, or address fraud or security issues. Where permitted, we will notify you before making such a disclosure.

5.4 Business Transfers

If AI Model Comparator is involved in a merger, acquisition, or sale of assets, your information may be transferred as part of that transaction. We will notify you via email and/or a prominent notice on the Service before your data is transferred and becomes subject to a different privacy policy.

6. Data Security

We maintain a written information-security programme that includes the following technical and organisational measures:

No system is perfectly secure. While we take these measures seriously, we cannot guarantee absolute security and encourage you to use a strong, unique password and enable two-factor authentication where available.

7. Data Retention

8. Your Rights and Choices

Depending on your location, you may have the following rights regarding your personal data. To exercise any of them, contact us at the address in Section 12.

We will respond to verified requests within 30 days (or the period required by applicable law). We may need to verify your identity before processing a request.

9. International Data Transfers

Our servers are located in the United States. If you access the Service from outside the US, your data will be transferred to and processed in the US, which may have different data-protection laws than your country. Where required (e.g., for transfers from the European Economic Area), we rely on Standard Contractual Clauses or other approved transfer mechanisms to ensure an adequate level of protection.

10. Children's Privacy

The Service is not directed to children under 13 (or under 16 in the EEA). We do not knowingly collect personal data from children. If you believe we have inadvertently collected data from a child, please contact us immediately and we will delete it.

11. Changes to This Policy

We may update this Privacy Policy from time to time. If we make material changes, we will notify you by email (to the address on your account) and/or by displaying a prominent notice within the Service at least 14 days before the changes take effect. The "Last updated" date at the top of this page will always reflect the most recent revision. Your continued use of the Service after the effective date constitutes acceptance of the updated policy.
