Privacy Policy

Last updated: November 2026  ·  Applies to the PinAnnotation Chrome extension and pinannotation.com

PinAnnotation is a Pinterest research and downloading tool. This policy explains what data we handle, why, and how you can contact us about it. In short: we do not sell your data.

What data we handle

• Website content. When you are on Pinterest or Instagram, the extension reads the visible page — image URLs, board metadata, and page HTML. Pinterest page HTML is sent to our server only when you request annotation keyword extraction.
• Web history. The extension reads the current tab URL to detect whether you are on a supported Pinterest or Instagram page. It does not read your browsing history or any other tabs.
• Authentication information. If you create a free account with Google Sign-In, we store your Google email address, display name, and profile picture URL. We also generate and store a license key tied to your account.
• Usage counters. We store counts of how many keyword extractions and board downloads you have used, so we can enforce free-tier limits.

How we use your data

• Locally in your browser. Selected image URLs, format preferences, and per-board selections are stored in chrome.storage.local. This data never leaves your device unless you explicitly request a download or keyword extraction.
• On our server. Pinterest page HTML is sent to pinannotation.com/api.php for keyword extraction, and the results are returned immediately. The HTML is processed in memory and is not retained after the response.
• Account data. Your Google email, name, profile picture, license key, and quota counters are stored in a JSON file on our server for as long as your account exists. This is required to make your license key work across devices.

What we do not collect

• Names, postal addresses, or phone numbers
• Health or medical information
• Financial information, payment cards, or bank details
• Passwords or credentials (Google handles authentication)
• Personal communications (emails, texts, chat)
• Precise geographic location
• Keystroke logging or click tracking

We do not use analytics trackers, advertising networks, or fingerprinting. We do not share data with third parties for advertising or lending purposes.

Data retention

Data deletion

To delete your account and all associated data — including your license key, quota counters, and any stored email — email us at the address below. We will confirm deletion within 7 days.

Third-party services

When you sign in, Google handles authentication. Google's own privacy policy applies to that process. We only receive your email, display name, profile picture URL, and a stable user identifier — nothing else.

Children

PinAnnotation is not directed at children under 13. We do not knowingly collect data from anyone under 13. If you believe a child has created an account, contact us and we will delete it.

Changes to this policy

If we change how we handle data, we will update the "Last updated" date at the top of this page. Continued use of the extension after a change means you accept the updated policy.
