PRIVACY POLICY — PROLIFIC NIGHT SHIELD
===================================================================
Last Updated: August 2026
1. INTRODUCTION & OUR PRIVACY PHILOSOPHY
Prolific Night Shield is designed with a strict privacy-first philosophy. We believe your browser extension should enhance your workflow without spying on you. This extension does NOT collect, track, store, or transmit any personally identifiable information (PII), survey responses, account credentials, or browsing activity.
-------------------------------------------------------------------
2. DATA COLLECTION AND USAGE
-------------------------------------------------------------------
- Zero Data Collection: We do not collect any personal data or usage analytics.
- No External Servers: The extension operates locally inside your browser and does not send any of your information to external remote servers.
- No Tracking / Telemetry: There are no hidden trackers, third-party analytics scripts, or diagnostic telemetry built into Prolific Night Shield.
-------------------------------------------------------------------
3. EXPLANATION OF REQUESTED PERMISSIONS
-------------------------------------------------------------------
To function properly, Prolific Night Shield requires specific Chrome permissions. Below is a detailed, transparent breakdown of why each permission is needed:
a) "storage" Permission
- WHY WE NEED IT: To save your extension preferences (such as your chosen dark theme mode, compact mode toggle, earnings highlight toggle, promo banner hiding setting, trial status, and license activation key).
- HOW IT IS USED: Your preferences are saved strictly on your local browser using Chrome's `chrome.storage.local` API. They never leave your device.
b) Host Permissions ("https://app.prolific.com/*", "https://www.prolific.com/*", "https://prolific.com/*")
- WHY WE NEED IT: To allow content scripts and CSS stylesheets to run on Prolific pages.
- HOW IT IS USED: This permission enables the extension to:
• Modify website colors and apply your selected dark theme (Classic Dark, Dim, Sepia, Matrix, Midnight).
• Render the quick floating theme toggle button directly on Prolific web pages.
• Scale UI elements for Compact Mode and highlight study reward amounts.
• Automatically hide promotional banner clutter for a clean interface.
- SCOPE: Access is strictly limited to Prolific domain URLs. The extension cannot and does not read or interact with any other websites you visit.
-------------------------------------------------------------------
4. THIRD-PARTY SERVICES & PURCHASES
-------------------------------------------------------------------
Prolific Night Shield offers a Pro upgrade processed via Gumroad (https://gumroad.com).
- Payment details, transaction processing, and license key generation are handled entirely on Gumroad's secure external platform.
- Prolific Night Shield itself does not handle, store, or process any payment or credit card details.
-------------------------------------------------------------------
5. DATA SECURITY & CONTROL
-------------------------------------------------------------------
Because all data (your theme and feature preferences) is stored locally on your machine:
- You retain 100% control over your data.
- Clearing your browser cache or uninstalling the extension will completely remove all stored extension settings.
-------------------------------------------------------------------
6. CHANGES TO THIS PRIVACY POLICY
-------------------------------------------------------------------
If any changes are made to this Privacy Policy in future updates, the updated policy will be posted in this file and reflected in extension updates.
-------------------------------------------------------------------
7. CONTACT & SUPPORT

If you have any questions or concerns regarding this privacy policy or the extension, please reach out via our Gumroad support page.
