# Cookie Lifetime Extender

Make your tracking resistant to the latest tracking preventions and extend your first-party cookie lifetime across all major browsers with the **Cookie Lifetime Extender.**

Modern browsers like Safari and Firefox are enforcing stricter privacy policies to curb long-term and cross-site tracking. While these changes aim to protect users, they also limit the lifespan of first-party cookies, even when server-side tracking is in use.

For example:

* Safari (ITP 2.3+, especially version 16.4 and newer) limits first-party cookies to just **7 days** if they’re set via a server that doesn't share the same subnet (first 2 octets of the IP address) as the website content.
* Firefox (ETP) applies similar restrictions, especially to cookies related to known tracking behaviors or domains not closely associated with the website host.

These restrictions lead to:

* Shortened cookie lifetimes (1–7 days);
* Broken user journeys;
* Missed conversions and attribution gaps;
* Reduced campaign performance and reporting accuracy.

With **JENTIS’ Cookie Lifetime Extender**, you can confidently preserve cookie lifetimes in the face of browsers' privacy restrictions. The feature ensures your tracking remains **accurate**, **durable**, and **compliant**, without compromising performance or setup complexity.

* Maintain **full cookie lifetime** in Safari, Firefox, and other privacy-focused browsers;

* With built-in verification to ensure a reliable setup.
