The Safari ITP Conundrum: How to Maintain First-Party Data Without an Expiration Date

Safari's Intelligent Tracking Prevention (ITP) presents challenges for marketers by limiting the lifespan of first-party cookies to seven days, potentially hindering personalized marketing efforts and accurate data attribution. This change affects the ability to maintain a comprehensive view of customer interactions, as users returning after a week are treated as new visitors, disrupting retargeting and data fidelity. To address this issue, Twilio Segment's Edge SDK offers a solution by utilizing server-side cookies, which are less likely to be restricted by ITP due to their enhanced privacy controls. This approach allows for extended data retention and better management of first-party data while respecting user privacy. By leveraging Cloudflare's infrastructure, Segment's Edge SDK provides a means to maintain customer data for up to 365 days, enabling more effective and privacy-conscious data collection and personalization strategies.
