The Data Privacy Act of 2012 (Republic Act No. 10173) applies when a message contains personal information, such as a name, a schedule, or a school detail. This notice says what Linaw AI does with a message. Linaw does not publish an NPC registration number.
1. On this device
Preferences (detail, wording, delivery, and Auto-Clarify or Manual) stay in localStorage under linaw.preferences.v1. Listen speed stays under linaw.listen.rate. An optional name and email stay under linaw.auth.v1. Saved pieces stay under linaw.pieces.v1, up to 20,000 characters each, and only after you press Save on this device. The extension keeps the same preference fields, plus reading display choices, in chrome.storage.local. None of that is sold.
2. What can leave the device
Source text is sent to Gemini or the gateway only when a model key is set on the server. With no key, POST /api/adapt runs the offline adapter and the text is not sent to a model. A share link leaves the device when you send it, because the source is inside the URL. Listen uses the browser’s speech engine. Some voices stay on the device, and some send the spoken line to the browser vendor. The hosted app sends the source sentence and the claim to https://linaw-nli.onrender.com/predict for the semantic check. Linaw does not store that exchange.
3. What we do not collect
There is no advertising network. Vercel Web Analytics counts page views, and a Clarify click records the detail and wording choices only. The pasted message, the clarified note, and the account email are not in that count. We do not sell messages. The server does not write source text to disk and does not log it.
4. How long it stays
A successful model answer is kept in server memory, up to 50 notes, so the same source, detail, and wording are not sent again. That memory is gone when the server process stops. Saved pieces stay in the browser until you delete them in My Content or clear site data. Sign out removes the optional name and email. Saved pieces stay until you remove them.
5. The extension
The companion reads page text only after you clarify a selection, or after you turn Auto-Clarify on. Pending text is cleared when the panel takes it. Auto-Clarify is off until you opt in. It never runs silently.
6. Your choices
You can delete a saved piece, sign out, or clear this site’s data in the browser. That is how access, correction, and deletion work. There is no separate privacy desk.
7. Children and contact
Linaw is not directed at children. If you find a leak, open an issue on the project repository. Do not paste a real personal message into a public issue. Use the campus-pilot sample instead.
