About
Reach your encrypted Helvety data from a Chromium side panel while you browse. After email sign-in and a passkey unlock, the panel decrypts your tasks, notes, contacts, links, and folders on your device so you can read, create, edit, delete, and reorder them without opening the web app. This is an open beta and is not in the Chrome Web Store yet, so you install it manually from a GitHub release.
Open beta and how you get it
Free with published source on GitHub; see the repository LICENSE for the exact open-source terms. The extension is in open beta and not yet published to the Chrome Web Store, so installation is manual: use the Go to App button on this page to open GitHub Releases, download the packaged build, and load it unpacked in your browser. Expect rough edges while the beta matures.
What you can do after unlock
- Sign in with an email one-time code (new or existing Helvety account), then unlock end-to-end encryption with your passkey.
- Browse decrypted tasks, notes, contacts, links, and folders in grouped, edit-first lists.
- Create, edit, delete, and reorder records (save-first create: new items open as empty forms and are stored on first save), and link entities across apps from the edit form.
- Open any item in the matching helvety.com app with one click.
Privacy and unlock model
Decryption happens inside the extension, and master keys live in the extension's own storage behind a passkey unlock, separate from helvety.com. Unlocking the website does not unlock the extension, and the extension never receives the web device-trust cookie. It needs a Chromium browser with the Side Panel API (Chrome 114 or newer, or current Edge).
Beta requirements
Decrypted lists and writes require passkey unlock support enabled for your installed extension id on Helvety Auth. See the GitHub README for the current setup checklist and known limitations.
