Chrome Extension
Privacy
Policy.
A public record of what Dex accesses, where processing occurs, how long information remains, and the controls available to each user.
00
Preamble
Purpose
Dex manages Chrome downloads and inspects downloadable resources on the current web page.
This policy describes the data Dex accesses to provide those functions. Download, tab, page-resource, and settings data is processed locally in the browser and is not transmitted to the developer.
I
Access
Data accessed
Information used by Dex features
Dex accesses only the information needed to display and control downloads, open its in-page surfaces, and identify resources the user may choose to download.
Tab context
The URL and title of the active or target browser tab.
Page resource information
Resource URLs, element titles or alternative text, media dimensions and duration, resource type, and observed transfer size.
Extension preferences
User-selected settings, panel size, and a bounded list of pending Chrome download identifiers.
Dex does not request or read browser cookies, form input, passwords, authentication tokens, personal communications, payment information, health information, or precise location. When a user explicitly copies a displayed URL, Dex writes that selected value to the clipboard but does not read clipboard contents.
II
Process
Processing
Local by default, original host when required
Dex has no separate service that receives browsing, download, or settings data.
Inside Chrome
Chrome download events and user actions
Local Dex processing and display
Chrome extension storage when persistence is needed
Original resource host
A download or page resource needs a size check
Dex sends a
HEAD or bounded Range request directly to that resource URLOnly response metadata or the requested byte range is used
The request goes to the resource's existing HTTP or HTTPS host. It is not redirected through a Dex backend or a separate third-party service.
III
Retain
Storage and retention
Each data class follows its product lifecycle
Settings
- Stored with
chrome.storage.sync. - Remain until reset, removal, or uninstall.
- Chrome may synchronize them according to the user's Chrome sync configuration.
Local extension state
- Panel size and pending download identifiers use
chrome.storage.local. - The pending list is bounded and entries are removed as they are resolved.
- Local extension storage is removed when Dex is uninstalled.
Page inspection
- Results are held in memory for the active page session.
- The resource cache is bounded.
- Inspection results are not uploaded by Dex.
Downloads
- History and downloaded files are managed by Chrome and the operating system.
- Users can remove history entries or files through Dex, Chrome, or the operating system.
IV
Control
Commitments and controls
No advertising, sale, or unrelated use
A
Sharing and advertising
Dex does not sell, rent, share, or transfer user data to the developer, advertisers, data brokers, or other third parties. It does not use data for advertising, profiling, creditworthiness, or purposes unrelated to its stated functionality.
B
Security
Dex uses Chrome extension APIs and local extension storage. Release builds package all executable code locally and do not download or run remote code.
C
User controls and deletion
Users can reset Dex settings, clear Chrome download history, delete downloaded files, reload a page to discard session resource results, manage Chrome sync, or uninstall Dex to remove extension storage.
V
Limited Use
Chrome Web Store Limited Use
Data is used only for Dex's user-facing purpose.
Dex's use and transfer of information received from Google APIs complies with the Chrome Web Store User Data Policy, including the Limited Use requirements. Dex uses such information only to provide or improve its download-management and resource-inspection features.
