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.
