Privacy Policy — Swain

Last updated: 2026-10-05

Summary

Swain is a personal browser extension. It does not collect, store, transmit, or share any user data. Everything it does happens locally on this device.

What it does

• Records the audio (and, in "All" mode, video) of the active call in a supported browser tab, only when "Start recording" is clicked.
• Saves the resulting file(s) directly to the browser's Downloads folder.
• Remembers the last-chosen recording mode locally, using the browser's storage.local API, so it doesn't need re-selecting each time.

What it does not do

• It does not send any data — recordings, metadata, or anything else — to any server. There is no backend; it has none to send data to.
• It does not read messages, contacts, chat history, meeting content, or any page content beyond detecting which call is active (to label the recording) and showing a small on-page recording indicator.
• It does not use analytics, tracking, or advertising of any kind.
• It only runs on a small, fixed set of supported call-website tabs — nowhere else.

Recordings

Recorded files are written straight to the local Downloads folder using the browser's downloads API. The extension does not keep a copy, does not read the file back afterward, and has no way to access it once saved.

Third parties

This extension does not integrate with, or share data with, any third-party service.

A note on call-recording laws

Recording a call may require the other participant's knowledge or consent depending on jurisdiction — some places require only the recording party's consent, others require everyone on the call to agree. This is a legal question about how the extension is used, not something the extension itself can determine or enforce.

Changes to this policy

If this policy changes, the update will be reflected here with a new "Last updated" date.
