Privacy Policy

Effective Date: October 26, 2025
Maintained by: YvonLabs - yvonlabs.plentiful987@passmail.net

Overview

YvonLabs builds small, independent browser utilities that run entirely on your device.
We never collect analytics, usage data, or personal information. All processing occurs locally, in your browser.

This unified privacy policy applies to all YvonLabs products, including:

ToastKit - one-click site reset (cookies, cache, permissions)
HeaderCheck - HTTP header and privacy posture analyzer
Future YvonLabs tools or sites operating under the same principles

Data Collection

YvonLabs projects do not:

Collect or transmit personally identifiable information
Log user activity or browsing history
Send any data to remote servers or third-party APIs
Use cookies or persistent tracking

All actions - such as clearing data, computing a score, or rendering UI elements — occur entirely within your browser or device session.

Permissions

Each tool requests only the minimal permissions necessary for its local function.

Project	Permissions	Purpose
ToastKit	`browsingData`, `activeTab`, `storage`	Reset cookies, cache, and permissions for the current domain only
HeaderCheck	`declarativeNetRequest`, `activeTab`	Inspect HTTP headers for the current page
Web Projects	n/a	Static content only, no active data collection

YvonLabs projects never use these permissions for analytics, telemetry, or remote communication.

Third-Party Services

YvonLabs products do not integrate with third-party analytics, ad networks, or telemetry frameworks.
No calls are made to services such as Google Analytics, Meta Pixel, or other tracking endpoints.

All assets and operations are hosted on privacy-respecting infrastructure and are transparent in their repositories.

Stay Updated

This policy may evolve to reflect product or regulatory changes.
The latest version will always be available at: 👉 https://yvonlabs.github.io/docs/privacy-policy
