Privacy Policy for Ephemeral Tab

Ephemeral Tab is a Chrome extension that isolates cookies, cache, and web storage in tabs and websites explicitly selected by the user. We believe privacy is a fundamental right, and our architecture is designed from the ground up to operate without collecting or transmitting any personal data.

The extension may store the following information locally on the user's device:

• Hostnames where the user explicitly enables protection.
• Internal rule identifiers required to apply the protection.
• Temporary tab identifiers and random isolation tokens while Chrome is running.
• The approximate time when a website preference was enabled.

• Locally stored hostnames are used exclusively to remember the websites where the user requested automatic protection.
• Temporary tab identifiers and isolation tokens are used exclusively to maintain an isolated browsing session inside the selected tab.

Ephemeral Tab operates with absolute data integrity:

• No External Transmission: Does not transmit data to the developer or external servers.
• No Telemetry: Does not use analytics, tracking, or telemetry scripts.
• No Monetization: Does not sell, rent, or share user information.
• No Profiling: Does not use data for advertising, profiling, or behavioral tracking.
• No Remote Code: Does not execute remotely hosted code; all logic is fully packaged locally.

All processing takes place locally on the user's device.

• Temporary tab data is deleted immediately when the protected tab or its browsing session ends.
• Remembered website hostnames remain in Chrome's local extension storage until the user disables protection for the associated website or uninstalls the extension.
• Users can instantly remove all stored extension data at any time by uninstalling Ephemeral Tab from chrome://extensions.

Ephemeral Tab requests access to tabs, HTTP and HTTPS websites, local extension storage, declarative network rules, and packaged scripts. These permissions are used exclusively to:

• Block Cookie and Set-Cookie headers on selected tabs.
• Prevent persistent HTTP caching.
• Isolate or block website storage APIs (such as LocalStorage and IndexedDB).
• Maintain protection while a tab navigates across pages.
• Remember websites selected by the user.

Information obtained through Chrome APIs is used only to provide the extension's user-facing isolation functionality. It is not transferred for advertising, profiling, or unrelated purposes, and it is not made available for human review.

Any material changes to this policy will be published on this page and reflected in the Chrome Web Store listing where required.
