AEO Audit by Cintra — Privacy Policy

This page describes what data the AEO Audit by Cintra Chrome extension collects, how we use it, and how to request deletion. It applies only to the extension, not to cintra.run itself.

What we collect

Email address

When you first use the extension, you enter an email address. We store this in our database (Neon Postgres) associated with your audit history. We use it to enforce rate limits (so a single user cannot exhaust our LLM budget) and to send occasional product updates about Cintra.

Page URLs you audit

When you click Audit on a page, the page URL is sent to our server (https://cintra.run/api/audit) and stored in our audit logs. This lets us enforce rate limits and understand which pages users find valuable to audit. We do not monitor your browsing history — only the pages you explicitly audit.

Rendered page HTML

When you run an audit, the rendered HTML of that single page is sent to our server so we can analyze headings, schema, meta tags, and content. We do not persist the HTML. It is used transiently to generate the audit and then discarded. The URL is kept in logs; the HTML content is not.

IP address

Server-side request logs capture the IP address of the machine making each audit request. We use this for rate limiting. IPs are not tied to email addresses in any public-facing export.

Install ID

On first run, the extension generates a random UUID and stores it locally in chrome.storage.local. This ID is sent with each audit request and used for layered rate limiting (so a user cannot bypass limits simply by rotating email addresses). The install ID contains no personal information.

What we do not collect

• Browsing history from tabs other than the one you audit
• Keystrokes, clicks, or mouse movements
• Form inputs, passwords, or authentication tokens
• Cookies or session state
• Screenshots of any kind
• Data from other tabs or other extensions

The extension runs only when you click its icon, and only on the tab you clicked it on. It does not run in the background.

How we use your data

• To run audits and enforce daily usage limits
• To send occasional product updates about Cintra. You can opt out anytime by emailing support@cintra.run.
• To contact you about the extension (bug reports, changes)
• To analyze aggregate usage (which page types are audited most, etc.) for product improvement

Sharing and sub-processors

We do not sell your data and we do not share it with advertisers or data brokers. Data flows only to the service providers needed to operate the extension:

• Vercel — hosts our API server. Vercel privacy policy.
• Neon — hosts the Postgres database storing your email and audit history. Neon privacy policy.
• Google (Gemini API) — receives the page content we send for the qualitative portion of the audit. Content sent to Gemini is not retained long-term per Google's API policy. Gemini API terms.
• Slack — receives an internal notification when a new email signs up, so our team knows to welcome you. Slack privacy policy.

Data retention and deletion

Your email and audit logs are retained until you request deletion. Email support@cintra.run with the email address you registered and we will delete your record and all associated audit rows within 7 business days.

Policy compliance

This extension complies with the Chrome Web Store Developer Program Policies. Specifically:

• We do not sell or transfer user data to third parties, apart from the approved sub-processors listed above.
• We do not use or transfer user data for purposes unrelated to the extension's single purpose (page-level AEO audits).
• We do not use or transfer user data to determine creditworthiness or for lending purposes.

Changes to this policy

If we materially change how we collect or use data, we will update this page and the Last updated date at the top. For significant changes we will also email existing users.
