Hi folks, Just to let you know, what's going on with Safari and other WebKit based browsers. This will probably affect everyone, which wants to use "TW Browser Storage plugin", which uses LocalStorage
There are some reactions already <https://ar.al/2020/03/25/apple-just-killed-offline-web-apps-while-purporting-to-protect-your-privacy-why-thats-a-bad-thing-and-why-you-should-care/>, but who knows. ... have fun! mario Cite form: > https://webkit.org/blog/10218/full-third-party-cookie-blocking-and-more/ at > 2020.03.26 12:06 > 7-Day Cap on All Script-Writeable Storage > > Back in February 2019, we announced that ITP would cap the expiry of > client-side cookies to seven days. That change curbed third-party scripts’ > use of first-party cookies for the purposes of cross-site tracking. > > However, as many anticipated, third-party scripts moved to other means of > first-party storage such as LocalStorage. If you have a look at what’s > stored in the first-party space on many websites today, it’s littered with > data keyed as various forms of “tracker brand user ID.” To make matters > worse, APIs like LocalStorage have no expiry function at all, i.e. websites > cannot even ask browsers to put a limit on how long such storage should > stay around. > > Now ITP has aligned the remaining script-writable storage forms with the > existing client-side cookie restriction, deleting all of a website’s > script-writable storage after seven days of Safari use without user > interaction on the site. These are the script-writable storage forms > affected (excluding some legacy website data types): > > - Indexed DB > - LocalStorage > - Media keys > - SessionStorage > - Service Worker registrations > > A Note On Web Applications Added to the Home Screen > > As mentioned, the seven-day cap on script-writable storage is gated on > “after seven days of Safari use without user interaction on the site.” That > is the case in Safari. Web applications added to the home screen are not > part of Safari and thus have their own counter of days of use. Their days > of use will match actual use of the web application which resets the timer. > We do not expect the first-party in such a web application to have its > website data deleted. > > If your web application does experience website data deletion, please let > us know since we would consider it a serious bug. It is not the intention > of Intelligent Tracking Prevention to delete website data for first parties > in web applications. > -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
