ScreenBolt — Privacy Policy

Last Updated: March 16, 2026

Data Collection

ScreenBolt does NOT collect:

• Personal information
• Usage analytics or telemetry
• Browsing history
• Screenshots or recordings
• IP addresses
• Device identifiers
• Any form of user data

Data Storage

All data created by ScreenBolt is stored locally on your device using Chrome's built-in storage APIs:

• Settings are stored in chrome.storage.sync (synced across your Chrome devices via your Google account, if sync is enabled)
• Capture history metadata (thumbnails, timestamps, filenames) is stored in chrome.storage.local
• Screenshots and recordings are saved to your local Downloads folder via Chrome's downloads API

No data is ever sent to external servers.

Data Processing

• All screenshot capture and stitching happens in your browser
• All image annotation and editing happens in your browser
• All video recording and compositing happens in your browser
• MP4 conversion (when requested) uses ffmpeg.wasm, which runs entirely within your browser's WebAssembly sandbox
• Clipboard operations use Chrome's offscreen document API within the extension sandbox

Third-Party Services

ScreenBolt does not use any third-party analytics, tracking, advertising, or data processing services.

The only external resource optionally loaded is ffmpeg.wasm from a CDN (jsdelivr.net) when you choose to convert a recording to MP4 format. This is a client-side WebAssembly library — no user data is sent to the CDN; only the library code is downloaded.

Permissions

ScreenBolt requests the following Chrome permissions, each with a specific purpose:

Permission	Purpose
activeTab	Access the current tab to capture its visible content
tabCapture	Capture tab video/audio stream for screen recording
desktopCapture	Capture full screen or window for screen recording
downloads	Save captures and recordings to your Downloads folder
storage	Store preferences and history metadata locally
offscreen	Create offscreen document for clipboard copy operations
scripting	Inject selection overlay UI when capturing a selected area
notifications	Show optional notifications after capture completion
alarms	Maintain background service during active recording sessions

Host Permissions

ScreenBolt requests <all_urls> host permission to enable:

• Content script injection for area selection overlay on any web page
• Full-page screenshot stitching on any web page
• Recording controls widget injection during screen recording

This permission is used only when you actively initiate a capture or recording. No content is accessed, read, or transmitted from any page.

Children's Privacy

ScreenBolt does not knowingly collect any data from anyone, including children under 13.
