Fact Check: "Cookie durations can last up to 1825 days!"
What We Know
Cookies are small files created by websites that are stored on a user's device to enhance user experience and gather data about website usage. There are two main types of cookies: session cookies, which expire when the browser is closed, and persistent cookies, which remain on the device for a specified duration (Oyster HR, 2023).
The duration of persistent cookies can vary significantly. According to Google's documentation on Google Analytics 4, cookie expiration settings can be customized, allowing for durations that range from immediate expiration to a maximum of 25 months (approximately 750 days). However, some sources indicate that certain cookies can indeed be set for longer durations, potentially up to 1825 days (5 years) in specific contexts, particularly when set by third-party services (Oyster HR, 2023).
Analysis
The claim that cookie durations can last up to 1825 days is partially true. While it is accurate that many cookies, especially those used for tracking and analytics, can be set for extended periods, the most commonly referenced maximum duration in standard practices is 25 months (or about 750 days) as per Google Analytics guidelines.
The Oyster HR Cookie Policy mentions that third-party cookies may have expiration periods determined by their respective owners, which could theoretically allow for cookies lasting up to 1825 days. However, this is not a standard practice across all websites and depends heavily on the specific implementation by third-party services.
Furthermore, the reliability of the sources varies. The information from Google Analytics is credible and widely accepted in the industry, while the Oyster HR policy provides a broader context but may not reflect the average cookie practices across all websites. Thus, while the claim holds some truth, it is not universally applicable to all cookies.
Conclusion
The verdict is Partially True. While it is possible for some cookies to last up to 1825 days, this is not a common practice and is dependent on specific third-party implementations. Most persistent cookies typically have a maximum duration of around 25 months, as indicated by major analytics platforms.
