Privacy Policy

Last Updated: July 2026

1. Information We Collect

We believe in data minimization. We only collect the absolute minimum required to provide our service:

  • • Account Information: Your Name, Email Address, and Facebook User ID (via Facebook Login).
  • • Ad Data: Read-only access to your Meta Ad Accounts (Ads, Creatives, and Links) solely for the purpose of checking their validity.
  • • Technical Data: Essential cookies required for maintaining your secure session.

2. How We Use Your Data

We use your data exclusively to:
a) Authenticate your identity.
b) Scan your specified ad accounts for broken links.
c) Send you notifications about found issues.
We never sell your data to third parties.

3. Data Security

Your Meta Access Tokens are encrypted at rest using industry-standard AES-128 (Fernet) encryption. We do not store your credit card information; all payments are processed securely by Lemon Squeezy.

4. Cookies & Analytics

We use the following types of cookies on our website:

  • • Essential Cookies: Required for authentication and maintaining your secure session (e.g., access_token). These cannot be disabled as they are necessary for the Service to function.
  • • Analytics & Advertising Cookies: We use Google Analytics (GA4), Google Ads Conversion Tracking, and Meta Pixel (Facebook Pixel) to understand how visitors interact with our website and to measure the effectiveness of our advertising campaigns (e.g., tracking successful sign-ups). These cookies and tracking pixels are only activated if you click "Accept All" on our cookie consent banner. If you click "Reject All", no analytics or advertising cookies are set and no tracking data is sent to Google or Meta.

Your cookie preference is stored locally in your browser via localStorage (not as a cookie itself) for a maximum of 12 months, after which we ask for your consent again. You can change or withdraw your choice at any time by clicking "Cookie settings" in the website footer.

We do not use any remarketing pixels or third-party tracking scripts beyond Google Analytics and Meta Pixel.
