Privacy Policy for DOsir Lens

Last updated: February 21, 2026

1. Information We Don't Collect

DOsir Lens does not collect, store, or transmit any personally identifiable information, including:

• Name, email, or contact information
• Browsing history
• Social media accounts or content
• Wallet addresses or transaction data
• Location data

2. How It Works

When you hover over a crypto ticker (e.g., $TOKEN):

1. The extension detects the token symbol locally in your browser
2. Fetches market data from DexScreener API (public data)
3. Caches results locally for 3 minutes to reduce API calls
4. Displays the data in a hover card

No data leaves your device except API calls to DexScreener and DOsir (both public endpoints).

3. Permissions Explanation

• activeTab: To detect token symbols on the current page
• storage: To cache token data locally (3-minute cache)
• Host permissions: To run on social media sites where tokens are mentioned

4. Third-Party Services

We use these external APIs solely for market data:

• DexScreener API - Real-time DEX trading data
• DOsir API - Token ratings (when available)

5. Data Retention

All cached data is stored locally in your browser and automatically expires after 3 minutes. You can clear this data anytime by:

• Clearing browser cache
• Uninstalling the extension

6. Changes to This Policy

We may update this privacy policy from time to time. Changes will be posted on this page with an updated date.
