HAR Analyzer AI Privacy Policy

Effective date: August 30, 2026 · Applies to HAR Analyzer AI (Chrome extension)

Short version: Your HAR files, network traffic, and analysis stay on your device. Nothing is uploaded to our servers. There are no accounts, no analytics SDKs, and no third-party trackers in this extension.

1. Who we are

This Privacy Policy describes how the HAR Analyzer AI Chrome extension (“the Extension”) handles information when you use it. The Extension is designed to analyze HTTP Archive (HAR) files and live network captures entirely on your machine.

2. Data we process — and where it stays

The Extension may process the following categories of data locally in your browser:

HAR files and live captures you import or record (URLs, headers, timings, optional bodies).
Analysis results (findings, scores, endpoint groups, inferred schemas).
Saved sessions you explicitly choose to store (via IndexedDB / extension storage on your device).
Ignore rules and UI preferences (theme, muted finding types) stored in extension local storage.
Optional on-device AI prompts derived from a redacted summary of findings (see below).

This data is not transmitted to the Extension’s developers or to any remote application server operated for this product. Processing happens in the extension’s own context on your computer.

3. On-device AI (Gemini Nano / Prompt API)

If you enable Chrome’s built-in on-device model and use AI features, a compact, redacted summary of analysis findings is sent only to the model running on your device via Chrome’s Prompt API.

Cookies, Authorization headers, and query strings are stripped before any text is prepared for the model.
The prompt is size-capped; the raw HAR is never passed to the model.
Availability and model download are controlled by Chrome, not by a custom backend of this Extension.

If on-device AI is unavailable, the Extension still works using deterministic, rule-based analysis only.

4. Permissions

The Extension requests only the Chrome permissions it needs to function:

sidePanel — to show the analyzer UI.
storage — to save sessions, preferences, and hand off live captures between the DevTools panel and the side panel.
DevTools access — to record live network traffic from the page you are inspecting (only while you start recording).

It does not request broad host permissions to read arbitrary websites in the background.

5. What we do not collect

No account registration or login.
No remote analytics, advertising, or crash-reporting SDKs embedded in the Extension.
No sale of personal data.
No automatic upload of HAR contents to external APIs for analysis.

Features such as Download HAR, HTML/PDF reports, CSV, Markdown, Postman, and OpenAPI exports create files on your machine. If you share those files with others or upload them elsewhere, that sharing is under your control and outside the scope of this Extension’s local processing.

7. Data retention

Saved sessions and preferences remain until you delete them or remove the Extension. Uninstalling the Extension removes its local extension storage associated with it (subject to Chrome’s normal behavior).

8. Children’s privacy

The Extension is intended for developers and technical users. It is not directed at children under 13 (or the equivalent minimum age in your jurisdiction).

9. Changes to this policy

We may update this Privacy Policy when the Extension’s behavior or legal requirements change. The “Effective date” at the top will be revised accordingly. Continued use after an update constitutes acceptance of the revised policy.
