Frequently Asked Questions

Questions? We've got answers.

How is this different from native ad tracking?

Native tracking relies on cookies and browser-side scripts that are blocked by ad blockers and iOS privacy features. We use server-side first-party tracking that bypasses these restrictions completely.

Will this work with iOS 14+ and ad blockers?

Yes! Our server-side tracking works even when customers use ad blockers or iOS 14+ devices. We maintain 100% accuracy regardless of client-side restrictions.

Do I need technical experience?

Not at all. Setup takes 5 minutes with our one-click integrations for Shopify and WooCommerce. No coding or developer required.

Which platforms do you support?

We support Meta (Facebook/Instagram), Google Ads, TikTok, Snapchat, Pinterest, and more. Data syncs automatically to all connected platforms.

Is Harper GDPR compliant?

Yes, we are fully GDPR and CCPA compliant. Our first-party tracking respects user privacy while maintaining accurate attribution.

Do you offer a free trial?

Yes! Start with a 14-day free trial. No credit card required. See the results before committing.
