Privacy Policy

Effective Date: April 27, 2026  ·  Last Updated: May 5, 2026

This Privacy Policy describes how Qheck ("we," "us," "our") collects, uses, stores, and shares information when you use the Qheck browser extension and the qheck.ai website ("the Service").

We have written this policy to be specific and accurate. Qheck is a browser extension that audits web applications by capturing screenshots and page data and sending them to a third-party AI service (Anthropic) for analysis. You should understand exactly what this means before using the Service.

If you do not agree with this Privacy Policy, do not install or use Qheck.

Summary in Plain Language

  1. Qheck takes screenshots of pages you audit and sends them to Anthropic for analysis.
  2. Don't run Qheck on pages with sensitive personal information (passwords, credit cards, health data) unless you're okay with that data being captured.
  3. Today, your audit data is stored on your device. Cloud sync, team accounts, and account features are on the roadmap and will be opt-in when they ship.
  4. You can delete sessions or your whole account anytime.
  5. We don't sell your data, train AI on it, or use it for advertising.
  6. Anthropic may retain data for up to 30 days under their trust and safety policy.
  7. AI output is fallible — verify findings before acting on them.

If any of this is not acceptable to you, do not use Qheck.

1. What Qheck Collects

When you use Qheck to audit a webpage, Qheck collects the following data from that page:

From every audited page:

From your interactions:

From your account:

2. What Qheck Does NOT Collect

Qheck does not collect:

Important Caveat About Form Inputs

While Qheck does NOT capture text typed into form fields by default, Qheck DOES capture screenshots of the visible page (which may include text visible on screen) and DOM snapshots that include the current value attribute of input elements at the moment of capture.

Do not enter sensitive information (passwords, credit card numbers, government ID, health information) into a page while Qheck is actively recording or running an AI Scan. We recommend running Qheck on test data, staging environments, or pages without sensitive personal information.

3. Where Your Data Goes

Sent to Anthropic (third-party AI provider):

When Qheck performs AI analysis, it sends to api.anthropic.com:

This data is sent over HTTPS. Anthropic's data handling is governed by Anthropic's Privacy Policy. As of this policy's effective date, Anthropic states that data sent through the API is not used to train their models by default.

Stored on Your Device:

In the current version of Qheck, the following data is stored locally in Chrome's chrome.storage.local on your device:

In the current version, this data does NOT leave your device unless you explicitly export a Qheck Deck. See “Sent to Qheck Servers” below for cloud features that are on the roadmap.

Sent to Qheck Servers:

In the current version of Qheck, the extension does not transmit your audit content (screenshots, DOM data, console output, Qheck Deck contents) to any Qheck-operated server. The extension communicates directly with Anthropic's API for analysis. Authentication servers store your email address, account tier, and usage counts — these servers do not receive audit content.

Cloud features are on the roadmap. Planned capabilities include cross-device session sync, team accounts, deck sharing, and a server-side Qheck Deck Analysis Dashboard. When any cloud feature ships, it will be opt-in per session, the data flow will be described in this policy, and we will notify users in-extension and via email before activating it. Until then, audit content stays on your device unless you explicitly export a Qheck Deck.

4. How We Use Your Data

We use data to:

We do NOT use your data to:

5. How Long We Keep Your Data

LocationRetention
Your device (sessions)Until you delete them or uninstall Qheck
Your device (flagged sessions)Protected from automatic cleanup
Our authentication serversUntil you delete your account
Usage countersReset monthly
Anthropic API (per their policy)Up to 30 days for trust and safety

6. Sharing Your Data

We do NOT sell your personal data.

We share data only:

7. Your Rights

Depending on your jurisdiction, you may have rights to:

Specifically:

We respond to data requests within 30 days.

European Users (GDPR)

If you are in the EEA, UK, or Switzerland, you have additional rights under GDPR. Our legal basis is your consent (granted by installation) and our legitimate interests in providing the Service. You may lodge a complaint with your local supervisory authority.

California Users (CCPA)

California residents have rights under CCPA. We do not sell personal information.

8. Children's Privacy

Qheck is not intended for users under 18. We do not knowingly collect data from minors. Contact hello@qheck.ai if you believe a minor has used Qheck.

9. Security

We use industry-standard security measures: HTTPS for all API communication, encrypted storage of authentication tokens, and minimal Qheck-side data exposure. In the current version of the extension, audit content stays on your device — see Section 3 for what changes when cloud features ship.

However, no security system is perfect. You acknowledge using Qheck at your own risk.

10. Cookies and Tracking

The Qheck extension does NOT use cookies or tracking pixels. The qheck.ai website may use minimal cookies for the waitlist form (provided by Formspree).

11. International Data Transfers

Qheck and Anthropic operate globally. Your data may be transferred to, stored in, and processed in countries other than your own, including the United States. By using Qheck, you consent to these transfers.

12. Changes to This Policy

We may update this Privacy Policy from time to time. We will update the "Last Updated" date and notify you of material changes via email or in-extension notice.

15. Important Disclaimers

Accuracy of AI Output

Qheck uses AI to analyze your audits. AI output can contain errors including factually incorrect findings, recommendations that don't apply to your codebase, severity assessments differing from your judgment, and occasional hallucinated claims. You are responsible for verifying findings before acting on them.

Audit Scope

Qheck audits what it can observe through the browser. It does NOT audit backend code, database integrity, or security vulnerabilities outside the rendered DOM. Network requests, performance metrics, console output, and runtime exceptions are captured in Dev Mode (Pro tier) via Chrome's debugger. Accessibility tree analysis, mobile viewport emulation, and code coverage are pending in v0.4 Phase 4.4.

No Warranty

Qheck is provided "as is" without warranties of any kind.
