Privacy Policy

1. Information We Collect

1.1 Account Information

When you purchase AdStackLens Pro, your email address is collected and processed by our payment provider (ExtensionPay / Stripe) to manage your license. We do not directly store your payment card information.

1.2 Usage Data

AdStackLens stores the following data locally on your device using Chrome's storage API:

• Extension settings and preferences
• Domain usage count (number of domains inspected per month)

This data never leaves your device and is not transmitted to any server.

1.3 Ad Detection Data

AdStackLens detects advertising elements on web pages you visit using two local mechanisms:

1. CSS selector matching against the page's DOM, to identify HTML elements belonging to known ad networks.
2. Direct introspection of advertising SDKs loaded by the page itself — specifically Prebid.js, Google Publisher Tag, and Amazon APS — to read runtime state such as bid responses, slot configurations, and targeting parameters via their public JavaScript APIs.

All detection and analysis is performed entirely within your browser. No data about the websites you visit, the ads detected, or any SDK runtime state is collected, transmitted, or stored on our servers or any third party.

2. How We Use Information

• To activate and manage your Pro license
• To enforce free-tier domain limits (locally on your device)
• To respond to support inquiries

3. Third-Party Services

We use the following third-party services:

• Stripe: Payment processing
• ExtensionPay: License management for Chrome extensions

These services have their own privacy policies governing the data they collect.

4. Data Retention

• License data is managed by Stripe/ExtensionPay per their retention policies.
• Local extension data is stored on your device and can be cleared by uninstalling the extension.

5. Your Rights

You may request access to, correction of, or deletion of your personal data by contacting us at the email address below.

6. Children's Privacy

AdStackLens is not intended for use by individuals under the age of 16. We do not knowingly collect personal information from children.

7. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last updated" date.
