Privacy Policy

Last Updated: January 2026

Our Commitment to Privacy

AltFlag is built on a simple principle: your browsing habits are yours alone. We don't want your data, we don't need your data, and we've designed our extension to ensure we never have access to it.

Overview

AltFlag ("the Extension") is committed to protecting your privacy. This privacy policy explains what information we collect (spoiler: none), how we use it, and your rights regarding your data.

Information We DO NOT Collect

Data Type	Collected?
Browsing history	No
Websites you visit	No
Personal information	No
IP addresses	No
Device fingerprints	No
Usage analytics	No
Location data	No

How AltFlag Works

AltFlag operates entirely on your local device:

1. Bundled Database: The entire website database (1,500,000+ sites) is included with the extension
2. Local Processing: When you visit a website, the lookup happens locally on your device
3. No Network Requests: AltFlag never sends requests to external servers for website lookups
4. Offline Capable: The extension works completely offline

Data Stored Locally (On Your Device Only)

The Extension stores the following data locally on your device only:

Data	Purpose	Shared?
Website database	Company headquarters locations	No
User settings	Your preferences (warning countries, display options)	No
Blocklist settings	Countries you've chosen to block	No
Browsing statistics*	Optional tracking of visits by country	No
Dismissed websites	Sites where you clicked "don't show again"	No

*Statistics are completely optional and can be disabled at any time. This data never leaves your device.

Cloud Sync (Optional)

If you enable Cloud Sync:

• Your settings only (not browsing data) are synced via your browser's built-in sync service
• This is handled entirely by your browser (Chrome Sync or Firefox Sync)
• We have no access to this data
• Your browser account credentials are never shared with us

Third-Party Services

AltFlag does NOT use:

• Google Analytics or any analytics service
• Advertising networks
• Social media trackers
• Crash reporting services
• Any third-party data collection services

Data Sources

The company location database is sourced from publicly available information:

• Tranco Top 1M domain list
• Wikidata company locations
• Manual curation from public sources

Permissions Explained

Permission	Why We Need It

alarms	To schedule optional periodic database updates
tabs	To show the country flag for the current website
activeTab	To access the current page's URL for lookup

Your Rights

• View: Check your settings anytime in the extension options
• Export: Export your settings to a JSON file
• Delete: Clear all data by removing the extension
• Disable: Turn off any feature (statistics, warnings, etc.) at any time
• Control: All your data remains on your device and under your control

Children's Privacy

AltFlag does not knowingly collect any information from anyone, including children under 13. Since we collect no data, there is no children's data to protect.

Changes to This Policy

We may update this privacy policy from time to time. Any changes will be reflected in the "Last Updated" date. Our commitment to collecting zero user data will never change.
