4. Advertising & Ad Targeting
SpotMarketCap displays ads through Google AdSense to support free access to our tools and data. Here's how advertising works on our site:
What Google AdSense Collects
Google may collect and use data for ad personalization, including:
- Cookies stored on your browser to track preferences and interactions
- Device identifiers and IP address (often anonymized)
- Browsing activity across sites that use Google services
- Demographic and interest data associated with your Google account (if signed in)
How Ads Are Personalized
Google uses this information to show ads that may be more relevant to your interests. For example, if you've previously searched for investment products, you might see ads related to financial services. Personalized ads help support our site while potentially showing you more useful content.
Third-Party Vendors
Google works with third-party vendors and ad networks that may also place cookies on your device. These partners help serve and measure the effectiveness of ads. You can view a list of Google's advertising partners at Google's Partner Sites.

Do Not Track
Some browsers offer a "Do Not Track" setting. While we respect this preference where possible, note that third-party ad networks may not honor DNT signals.
Note: Even if you opt out of personalized ads, you will still see ads on SpotMarketCap. They just won't be tailored to your interests and browsing history.
6. Data Retention
We retain different types of data for different periods:
- Account data: Retained while your account is active. You can delete your account and all associated data at any time from Settings.
- Portfolio data: Encrypted and stored until you delete it or delete your account.

- Authentication: We use Google OAuth for secure authentication without storing passwords.
- Infrastructure: Our site is hosted on Vercel with enterprise-grade security.
- Access Control: We limit access to user data to essential personnel only.
