What stays on your server
Your document, the sections built from it, the knowledge graph, the search index, and the docent’s question log all live in your own WordPress database and uploads directory. Living Manual has no hosted service holding your content, and no ability to read it.
What the free core sends, and when
Once, when you click Send on the Help & Feedback screen. Nothing else, ever. There is no activation ping, no usage telemetry, and no scheduled call.
That send carries your message, the email address you optionally provide, and these environment details: your site URL, your WordPress version, your PHP version, the Living Manual and Living Manual Pro version numbers, whether an Anthropic API key is set as a true or false value, whether a license key is set as a true or false value, your active theme name and version, your site locale, and whether the site is a multisite.
No key value is ever transmitted. The payload carries only whether a key exists, never what it is. The Help & Feedback screen prints every one of these values above the Send button so you can read the exact payload before you send it.
What Living Manual Pro sends
To Anthropic, using your API key: your document’s text during ingest, and reader questions plus the retrieved sections when the docent answers. This is how those features work, and the account it bills to is yours.
To Lemon Squeezy: your license key, when you activate, deactivate, or during the daily revalidation. This is how licensing works.
To Living Manual support, when you open a support ticket: your subject, description, reply address, license key, and the same environment details listed above. The license key is used to verify your entitlement and is stored only as a hash plus its last four characters, so the support site holds no usable key.
Deleting your data
Uninstalling Living Manual, as opposed to deactivating it, drops its tables and removes its options. Your uploaded PDFs remain in the WordPress media library where you can delete them like any other upload.
