Loom is a browser extension (and companion web app) that renders dual-language
subtitles with phonetic annotations on streaming video. This policy explains
exactly what data Loom sends out of your browser, and why.

WHAT WE SEND
When you activate Loom on a video, the extension reads the subtitle text from
the tracks the site already serves to your browser, deduplicates it, and sends
the unique subtitle strings to api.loom.nerv-analytic.ai for romanization
(e.g. "東京" → "Tōkyō") and per-character annotation (e.g. furigana, Pinyin).
Each video produces roughly one request per subtitle track when you activate
Loom; nothing is sent during playback after that. The request carries only the
subtitle text and the target language code. Romanization and annotation require
server-side language tools (MeCab, pypinyin, aksharamukha, and others) that
can't run in the browser — that is the sole reason any text leaves your device.

WHAT WE DON'T SEND
We do not send your account information, your viewing history, your playhead
position, any unique device identifier, or any browser-level telemetry.

OPTIONAL OWNER KEY
If you set an owner key, it is sent as an HTTP header on API requests to bypass
rate limits. It is stored only in your browser's local storage and is removed
when you uninstall the extension or clear it.

RETENTION
The Loom API processes requests in memory and does not archive subtitle text by
default. A future opt-in research pipeline may store anonymized text to train
language models; if and when that ships, it will be governed by an explicit
per-request opt-in flag you control, and this policy will be updated first.

THIRD PARTIES
We do not share data with third parties. We do not use analytics services. We
do not run advertising.

YOUR RIGHTS
Uninstalling the extension removes all locally-stored preferences and the owner
key. The Loom API holds no per-user records, so there is nothing server-side to
delete.
