English · 한국어

1. What we do not collect

ChartGrabber does not collect, transmit, sell, or share any of the following:

• Personally identifiable information (name, address, email address, age, identification numbers)
• Health, financial, or authentication information
• Your browsing history, the URLs you visit, or the content of the pages you visit
• The chart data the extension extracts for you
• Keystrokes, mouse movement, clicks, or any other analytics or telemetry

The extension contains no analytics SDK, no advertising SDK, and no third-party tracking of any kind.

2. How the extension processes page data

To do its job, ChartGrabber reads content from the page you are currently viewing — chart elements, the JavaScript chart objects on that page, and JSON responses the page itself requested. This processing happens entirely inside your browser, in memory, on the page you explicitly chose. Captured data is discarded when you close or reload the tab. None of it is transmitted anywhere.

Files you export (CSV, Excel, clipboard) are produced locally by your browser and saved to your own device.

3. What is stored on your device

Using chrome.storage.local — on your device only, never uploaded — the extension keeps:

• Your monthly usage count and the current month, so the free tier can be metered
• Timestamps of your last few extractions (no page URLs, no extracted values)
• If you buy Pro: your license key, which product it belongs to, and the last validation time

You can erase all of it at any time by removing the extension from Chrome.

4. The one network request we make

The only server the extension contacts on its own is api.gumroad.com, and only if you have entered a license key. That request contains your license key and the product identifier it is checked against, and is used solely to confirm that your purchase is still valid. It contains nothing about you or the pages you visit. It is sent when you activate a key and roughly once a day afterwards.

Gumroad is our payment and licensing provider and acts as merchant of record for the sale. Payment details are entered on their checkout page and are never seen or stored by ChartGrabber. See the Gumroad privacy policy.

5. Permissions and why they are needed

• storage — to remember your usage count and license status on your device.
• activeTab — to act on the tab you are looking at when you click the extension.
• alarms — to re-check your license roughly once a day.
• host permission for api.gumroad.com — to validate your license key.
• content scripts on http/https pages — charts can appear on any site, so the extraction engine must be able to run on the page you choose. It only reads a chart when you explicitly click one.

6. Children

ChartGrabber is a productivity tool intended for general audiences and is not directed at children under 13.

7. Changes

If this policy changes materially, we will update the date at the top of this page and note the change in the extension's Chrome Web Store listing.
