Chromy Privacy Policy

Effective date: June 19, 2026

Chromy does not collect, sell, transmit, or share personal information or browsing content.

Data Stored Locally

Chromy stores only the enabled or disabled state of Dark Mode and Reader Mode for each exact hostname. This data remains in Chrome's local extension storage on the user's device.

Website Access

Chromy asks for access to a website only when the user enables a mode there. Access is used solely to modify that page locally. When both modes are disabled for a website, Chromy removes its registered script and releases that origin permission.

Network Activity

Chromy has no backend, analytics, advertising, account system, or external API calls. Mozilla Readability is bundled locally and does not contact Mozilla.

Data Retention and Deletion

Site preferences remain until both modes are disabled, extension storage is cleared, or Chromy is uninstalled. Chrome removes extension data when the extension is uninstalled.

Changes

Material changes to this policy will be described in the extension's release notes and reflected by a new effective date.
