Alien Crow for Safari, Last updated 2026-10-26

TL;DR. Alien Crow has no developer analytics or telemetry service. Preferences and private collections are stored locally. Enabled features can request data from Reddit, load media, or open third-party websites as described below.

What is Alien Crow?

Alien Crow is a Safari Web Extension that enhances the Reddit browsing experience with themes, ad-blocking, keyboard navigation, saved-content tools, and over 100 other features. The extension runs in Safari. Its containing app provides setup information and extension status.

Data stored on your device

Your preferences and private collections use local extension storage. Depending on the features you use, this includes:

Module preferences, which features you have enabled and any options you have customized (e.g. theme choice, keyboard shortcuts).
Reading and comment thread state, such as seen comment counts, visited posts, and collapsed threads. Limits and retention depend on the enabled module.
User tags, notes, and saved content, when you use tagging, bookmarks, saved comments, or their folders.
UI state, such as your display language, panel positions, and dismissed welcome or update notices.
Saved tools and account names, such as custom feeds, reply templates, community shortcuts, and account names when you use those features.

These records are stored in Safari's browser.storage.local sandbox. Alien Crow does not send this local store to its developer. Exports create files on your device; you choose whether to share them. Website actions can send the information needed for that action to the relevant website.

Network access

The extension operates on Reddit pages. Network activity depends on the page, enabled modules, and actions you take:

Reddit features may request post, comment, community, or account data from Reddit. Enabled live-update modules can check for changes. Actions such as replying or account switching use Reddit's website and your current session where needed.
View Deleted Content opens the selected third-party service when you click its link: Reveddit or Unddit. The destination receives the requested thread URL and applies its own privacy policy. Alien Crow does not guarantee that archived content is available.
RSS Feed creates links to Reddit's RSS/XML feeds. Opening a feed contacts Reddit; a feed reader you choose may fetch it under that reader's own settings.
External media and links can contact media providers when content loads or plays, and third-party websites when you follow links. Their own privacy policies apply.

Privacy controls

Privacy Enhancer can remove known tracking parameters from links, reduce referrer information on external links, and hide matching tracking-pixel images. Hiding images with CSS does not prevent their network requests or block a page's analytics beacons. These controls do not make browsing anonymous.

Permissions

Safari grants Alien Crow the following permissions:

storage, to save your preferences locally.
activeTab, tabs, to open the Reddit page when you click the toolbar icon, and to refresh the page when you change settings.
webNavigation, to restore the classic-design preference during navigation when Classic Reddit is enabled, and send mobile Reddit URLs to www.reddit.com.
cookies, to set or remove Reddit's classic-design preference cookie when you change the Classic Reddit setting, and restore that preference during navigation.
Host access to *.reddit.com, so the extension can modify Reddit pages.

The extension's host access is limited to Reddit pages. This does not stop external links or embedded media from contacting their respective websites.

Third-party services

Alien Crow does not include a developer analytics or telemetry service. Reddit and any third-party sites or embedded media you use have their own services, scripts, and privacy practices.

Children's privacy

Alien Crow does not knowingly process data from children under the age of 13. Since Reddit's own terms require users to be at least 13, and Alien Crow only operates on Reddit, this requirement is enforced upstream.

Changes to this policy

If this policy ever changes, the "Last updated" date at the top will reflect the new revision. Material changes will also be mentioned in the extension's release notes.
