Privacy Policy

Effective date: June 2026  ·  Last updated: June 2026

1. What Data We Collect

We collect no data whatsoever.

Bulk PNG Grid Merger does not collect, log, or transmit:

• Personal information of any kind
• Images or files you upload
• Usage statistics or analytics
• Browser history or tab information
• Device identifiers
• Crash reports

2. How Your Images Are Processed

Images you drag, drop, or select are loaded directly into your browser's memory using standard Web APIs (URL.createObjectURL, HTML5 Canvas). All rendering, compositing, and export happen locally on your device.

No image data is ever uploaded to any server, cloud service, or third party. When you close the extension, object URLs are revoked and memory is released.

3. Permissions Used

The extension requests one permission:

• clipboardWrite — used only when you click "Copy PNG" to place the rendered image on your system clipboard. The extension does not read from your clipboard.

No "tabs", "history", "storage", "identity", or network permissions are requested.

4. Third-Party Services

The extension contains a link to Ko-fi for optional user support. This link only opens when you actively click it. Ko-fi is an independent service; please refer to their own privacy policy at ko-fi.com/privacy.

No other third-party services, CDNs, fonts, scripts, or analytics are loaded by the extension.

5. Data Storage

The extension does not use chrome.storage, localStorage, IndexedDB, or cookies. No data persists between sessions.

6. Children's Privacy

This extension does not collect data from anyone, including children under 13.

7. Changes to This Policy

If this policy is ever updated, the new version will be published at the same URL with an updated "Last updated" date. Because no data is collected, changes are expected to be minor clarifications only.
