GumKit does not operate any server and does not collect, store, or transmit any of your data to the developer.
Your Gumroad API token and optional OpenAI API key are stored only in your browser's local extension storage (chrome.storage.local). The extension communicates directly and only with the official Gumroad API (api.gumroad.com) and, if you enable the AI feature, the OpenAI API (api.openai.com), using the keys you provide.
Your customer/sales data retrieved for CSV export is written only to a file you download and is never sent to the developer or any third party.
Uninstalling the extension removes all locally stored data.
