What iyulab keeps and sends out through the Lowline app and this site.

The Lowline app

Your documents stay in the folder you choose. The app makes no account. Document contents, field values, file names, form names and folder paths are never sent anywhere, except by you through the chat below. These three are all the app sends off your computer.

• Chat. It sends something only once you choose a model and write to it. A model on this computer sends nothing out — getting it ready only downloads the model file from Hugging Face and the program that runs it (llama.cpp), or a newer build of it, from GitHub. Choose your own server, or a service you give a key for (OpenAI, Anthropic, Google, xAI), and it sends only there: the form as it stands and what you wrote — and the text and file name of a blank form file you pick to start from (HWP, PDF, Word or Excel, read on this computer) — when changing a form; the form and the text you pasted, when bringing records in from text; the form — with the field names and choices of the forms it refers to, and the names, field names and choices of the forms that refer to it — and your question, when asking about records. Asking about records sends no record's values — the counting is done on this computer. Keys are kept in Windows Credential Manager.
• Error reports. When the app fails, it sends iyulab only what is needed to fix it: which part failed and how, where in Lowline's own code, the app version and the Windows version. Reports are stored in Microsoft Azure (Korea Central) for 90 days; IP addresses are not stored. Until the first stable release, error reporting cannot be turned off; from then on it can be turned off in the app.
• Update checks. Every twelve hours — when the app starts, if that long has passed — it checks GitHub for a newer release and, when there is one, downloads its installer from GitHub in the background. You can turn this off under 정보 (About), and an update is installed only when you choose to install it.

This site

• Getting news. We keep the address you enter, the news you chose (the macOS version) and the language of the page on iyulab's server, and use them only to send news. The IP address you send from is not kept. The record stays until you send «stop» with the same address, and is deleted then.
• Nothing else is kept. This site uses no cookies, ads or visitor analytics. What you type into the page's blank is sent nowhere.

When this changes

If what the app or the site keeps or sends changes, this page changes first.
