Privacy Policy

Effective date: June 25, 2026

AssertHive builds AI-native quality tools, including WebTest AI and Agent Performance Lab. This policy explains what data our tools may handle and how that data is used.

Summary

Agent Performance Lab is local-first. Recording data is stored locally in the browser and is controlled by the user. The extension does not upload recorded sessions, prompts, responses, files, network metadata, governance findings, reports, private eval suites, or user settings to an external AssertHive server.

AssertHive does not sell user data. AssertHive does not transfer user data to third parties for advertising, creditworthiness, lending, or unrelated purposes.

Agent Performance Lab

Agent Performance Lab is a Chrome DevTools extension for recording, reviewing, scoring, governing, and exporting evidence from browser-based AI agent workflows. Recording is opt-in and starts only when the user turns it on.

Depending on the page being tested and the settings selected by the user, Agent Performance Lab may handle these data types locally:

• Website content: visible page text, prompts, responses, tool approval text, and browser-visible workflow evidence.
• Personal communications: chat-like prompt or response content when the user records an agent conversation.
• Web history: page URL, page title, and recording timestamps for pages the user chooses to record.
• User activity: recording start/stop activity, local session timeline events, tool-like activity, and extension settings.
• Authentication information: password-like or credential-like text may be detected if a user enters or displays it in a recorded prompt or page. Detected secrets are masked where possible before display or export.
• Personally identifiable information: names, email addresses, addresses, account identifiers, or similar information may be present if the user includes it in browser-visible content being recorded.
• Financial, health, or location information: these may be present if the user intentionally tests an agent workflow involving finance, payment, healthcare, travel, maps, addresses, or similar browser-visible content.

Local Storage And Retention

Agent Performance Lab stores local extension data in the user’s browser, including recording sessions, timeline events, network metadata, tool-like detections, governance reports, quality scores, local test cases, private eval suites, and settings.

This data remains on the user’s device until the user clears it, removes the extension, clears browser storage, or exports it manually.

User Controls

• Users choose when recording starts and stops.
• Users can clear local extension data.
• Users can disable DOM text capture or network metadata capture in settings.
• Users can review exports before sharing them outside the browser.

Chrome Web Store Limited Use

Agent Performance Lab uses handled data only for its single purpose: local browser-based AI agent observability, testing, governance, scoring, reporting, and repeatable local eval creation.

The extension does not sell, rent, transfer, or share user data with third parties. The extension does not use user data for advertising, creditworthiness, lending, or purposes unrelated to the extension’s single purpose.

WebTest AI

WebTest AI is a developer tool for browser-flow testing. Data handled by WebTest AI depends on how users configure and run it in their own development or CI environments. Test artifacts may include screenshots, traces, reports, logs, network evidence, and configured test data. Users control where those artifacts are stored and shared.

Website

The AssertHive website is a static documentation and product site. Our hosting provider may process standard operational information such as IP address, browser user agent, request path, timestamp, and error logs to serve the site, protect availability, and troubleshoot issues.

Security And Limitations

Agent Performance Lab masks detected secrets where possible, but browser-visible evidence can still contain sensitive content if a user records a page that displays it. Treat exported reports and evidence as sensitive artifacts and review them before sharing.

Browser mode can only observe what Chrome and the inspected page expose. Hidden backend model calls, server-side MCP calls, and exact token usage may be incomplete unless the agent platform exposes that data in the browser.

Changes

We may update this policy as AssertHive products evolve. Material updates will be reflected on this page.
