1. Summary
Hugging Fit is a browser extension you install on your own machine. It reads pages on huggingface.co that you are already viewing and adds a small UI on top of them. It does not run a backend, does not require an account, and does not transmit your activity anywhere we control.
2. Information stored locally
The following is stored in your browser via the standard chrome.storage API:
- Your VRAM target, KV-cache dtype, and headroom values.
- Your theme choice (midnight / aurora / daylight / forest / mono).
- Your runtime / app / library / task / license / "other tag" / language filter selections.
- Your panel, hover-dossier, and listing-page preferences.
- Hide-rule toggles and any custom CSS selectors you paste in.
- A short-lived cache of HF API responses (model metadata, file trees, config.json) used to populate the panel without re-fetching on every page.
Settings sync between signed-in browser instances via Chrome's storage.sync if you have Chrome Sync enabled — that traffic flows between your browser and your own Google account and is never visible to Hugging Fit.
3. Network requests
Hugging Fit makes requests only to huggingface.co:
- The same model API the site uses to display its own pages (/api/models/…, /api/models/…/tree/main).
- Public file URLs (/<org>/<repo>/raw/main/…, /<org>/<repo>/resolve/main/…) when you press the Download button.
No requests are made to any other domain. There are no analytics scripts, no third-party trackers, no error-reporting endpoints, and no calls to hugging.fit from inside the extension.
4. Permissions, in plain English
- storage — persist the settings listed above.
- downloads — trigger downloads of model files when you press the ↓ buttons.
- host_permissions: huggingface.co — read public Hugging Face API endpoints to populate panel data.
5. Cookies
The extension does not set or read any cookies. The marketing site at hugging.fit serves static HTML/CSS and runs no analytics — it does not set cookies either.
6. Children
Hugging Fit is a developer tool with no targeted audience. It does not knowingly collect any data from anyone, regardless of age, because it does not collect data at all.
7. Changes
If this policy changes — for example, if a future version of Hugging Fit ever gains optional telemetry — the change will be announced in the extension's release notes and reflected here with a new "Last updated" date. Optional features will always be opt-in.
