Your privacy is fully protected.
Short version: Blue Light Filter collects no personal data whatsoever. All settings are stored locally on your device using Chrome's built-in storage. Nothing is ever sent to any server.
About This Extension
Blue Light Filter is a Chrome extension that applies a warm amber overlay to every webpage you visit, reducing blue light exposure to ease eye strain and support healthy sleep. It is a purely local, client-side tool with no accounts, no analytics, and no external communication.
What We Do Not Collect
What Is Stored Locally
Blue Light Filter stores only your preferences using chrome.storage.local, which is a sandboxed storage area private to this extension on your own device. These settings are never transmitted anywhere.

|---|---|---|

Boolean | Whether the blue light filter overlay is turned on or off |
intensity |

scheduleEnabled |
Boolean | Whether the auto-schedule feature is active |
scheduleStart |
String (HH:MM) | The time of day the filter automatically turns on |
scheduleEnd |

You can clear this data at any time by uninstalling the extension or by clearing extension storage in Chrome's settings.
Permissions Explained
The extension requests only the permissions necessary to function:
- storage — Used exclusively to save and retrieve your local preferences (filter state, intensity, warmth, and schedule settings) as described above. No data is ever sent off-device.
- tabs — Required to send real-time settings updates from the popup to the active tab's content script when you adjust the filter. Without this, changes would not take effect until you reload the page.
- Content script on all URLs (<all_urls>) — The warm amber overlay must be injected into every webpage you visit to provide consistent blue light protection across all sites. No page content is read, recorded, or transmitted.
External Connections
The extension itself makes no network requests. The following are passive, user-initiated, or browser-standard behaviors:
- Google Fonts (Inter) — The popup UI loads the Inter typeface from Google Fonts for display purposes. This is a standard browser font request and is subject to Google's Privacy Policy. No extension data is transmitted.
- bushe.co — The popup contains a link to bushe.co. This link is only followed if you choose to click it.
Children's Privacy
Blue Light Filter does not collect any information from anyone, including children under the age of 13. The extension is a simple eye-care tool with no data collection of any kind.
Changes to This Policy
If this privacy policy is updated, the revised version will be published at this URL with an updated effective date. Given that this extension collects no data, substantive changes to this policy are unlikely.
