Privacy Policy — Substack Archive Button

Extension: Substack Archive Button
Last updated: 2026-08-08

Summary

Substack Archive Button does not collect, transmit, or store any personal data.

Data collected

This extension collects no data of any kind.

• It does not track browsing history.
• It does not read, copy, or transmit page content.
• It does not communicate with any external server other than the Substack API on the page you are already viewing.
• It does not use analytics, crash reporting, or telemetry.

Substack API calls

When you click Archive or Unarchive, the extension calls the Substack API endpoint /api/v1/inbox/archive on the same domain as the page you are viewing. This call uses your existing Substack session credentials (the same cookies your browser already sends to Substack). No data is sent to any third party.

Permissions

The extension is granted access only to substack.com and *.substack.com domains, which is the minimum required to function.

Changes

If this policy changes, the updated version will be published here.
