Privacy Policy for ScrollPoint Saver

Last Updated: August 6, 2025

Overview

ScrollPoint Saver is designed with privacy as a core principle. This extension helps users save and restore scroll positions on web pages while keeping all data completely local to their device.

Single Purpose

This extension serves one specific purpose: to save and restore scroll positions on web pages. Users can bookmark specific scroll locations on any webpage and quickly return to those positions later.

Data Collection and Storage

What Data We Collect Locally:

1. Scroll Positions: The vertical scroll position (scrollTop values) of scrollable elements on web pages
2. Page URLs: Website URLs where scroll points are saved (using window.location.href)
3. Element Selectors: CSS selectors to identify scrollable elements on pages (generated via DOM traversal)
4. Custom Names: User-provided names for saved scroll points

What Data We DO NOT Collect:

• Personal information (names, emails, addresses)
• Browsing history beyond scroll point URLs
• Content of web pages
• User credentials or authentication data
• Financial information
• Location data
• Communications or messages

How Data is Stored:

• All data is stored locally using Chrome's chrome.storage API
• No data is transmitted to external servers or third parties
• Data persists only on your local device
• No remote servers or databases are used

Technical Implementation Details

DOM Interaction:

• The extension scans web pages for scrollable elements using document.querySelectorAll('*')
• It checks CSS properties (overflow, overflowY) to identify scrollable containers
• Element selectors are generated using tag names and DOM hierarchy for later identification

Data Processing:

• Scroll positions are captured using element.scrollTop property
• Element identification uses CSS selectors (IDs, tag names, nth-child selectors)
• All processing happens locally in your browser

Permissions Justification

Storage Permission

• Purpose: Save scroll point data locally
• Usage: Stores scroll positions, URLs, and user-defined names using Chrome's local storage

ActiveTab Permission

• Purpose: Access the currently active tab
• Usage: Read scroll positions and inject navigation buttons on the current webpage

Scripting Permission

• Purpose: Inject content scripts into web pages
• Usage: Execute code to detect scrollable elements, save positions, and create navigation buttons

Host Permission

• Purpose: Work on all websites
• Usage: Allow users to save scroll points on any website they visit without manual site-by-site permission

Data Usage and Sharing

Local Processing Only:

• All scroll position calculations happen in your browser
• Element detection and selector generation occur locally
• No analytics or tracking data is collected

No Data Sharing:

• Zero data transmission to external servers
• No third-party integrations or data sharing
• No advertising or marketing use of data
• No user profiling or behavioral analysis

Data Retention and Control

User Control:

• Users can delete individual scroll points through the extension interface
• Users can delete all scroll points at once
• Users can toggle visibility of scroll point buttons
• Uninstalling the extension removes all stored data

Data Persistence:

• Data persists between browser sessions until manually deleted
• Data is tied to your Chrome profile and doesn't sync across devices
• No automatic data backup or cloud storage

Security Measures

Local Security:

• Data is protected by Chrome's built-in storage security
• No network transmission means no interception risk
• No external authentication or API keys required

Code Security:

• No remote code execution
• All functionality is contained within the extension package
• No external script loading or dynamic code evaluation
