Your library is yours.

If you sign in, your library and Sundays are stored in Kindling’s database under your account so you can open them on another phone or computer. Only you can see them. The Architect can see account tools (People, Inbox), not the stories in your library.

If you do not sign in, what you save stays on this device. Clear the browser and it can vanish. That is why sign-in exists — to keep your work, not to share it.

Kindling counts unique devices once a day so The Architect can see whether people are finding the shelf. That ping is a random device id and a date — not your library, not your name.

Saving a card with Add one never sends it to Grok. Gather on the “Shelf” page sends the passage or topic you typed — not your library. Grok does not get a copy of everything you have saved.

A few tools send only the scrap you just typed or dropped, for that one request: Fill a scrap, From this week, From a photo, Have Grok sort it, and Recommend (for a piece you want on the public shelf). We ask the API not to store that turn. xAI’s published rule is that they do not train on API inputs or outputs without explicit permission.

Kindling looks in a real library first. If Grok writes a card, that is a draft — check the source before you preach it. Models invent quotes and sound sure while they do it. Do not preach a line you have not seen in the original.

That is the honest line: Kindling will not train on your library. We will not send the whole library to anyone. If you use a helper, that one scrap is processed to make a card, then it lives in your library again — private.

Recommend is a request to publish. First-person stories, family anecdotes, and local-church tales are denied automatically. They never leave your library. Published quotes, documented history, and well-known public figures can go through after a source check.
