Introduction

Browsers are tightening third-party cookies, storage access, and tracking surfaces. The goal is better privacy; the side effect is that many existing integrations and analytics patterns need updates. Here’s a concise map of what’s changing and how to adapt.

Key Changes

Cookies and storage
Third-party cookie deprecation, CHIPS, and partitioned storage change how cross-site identity and state work. We outline first-party-centric design and server-side options.

APIs and permissions
Permissions for geolocation, notifications, and identity are getting stricter and more explicit. We cover best practices so your app stays functional and respectful of user choices.

Attribution and analytics
Measurement is shifting toward aggregated reporting and first-party data. We summarize Privacy Sandbox and server-side tagging so you can plan analytics and ads without relying on third-party cookies.

Action Items

We give a short checklist: audit cookie and storage usage, test in strict modes, and prefer first-party and server-side flows so your product stays compliant and future-proof.
