Description aaaaaaabcdefg123 2020-03-24 14:37:24 PDT

IIUC, the upcoming "7-Day Cap on All Script-Writeable Storage" [1] will cause loss of user generated data stored in IndexedDB. Telling the user to come back to the web app within every 7 days, or to use an alternative browser, are not a viable solutions to this problem. Implementing Persistent Storage [2] or something equivalent would still allow such web apps to be usable in Safari. While we are all for improving privacy (ironically we store the user generated data in IndexedDB rather than on our servers for exactly that reason), please do not delete our users' data for which they might have spent a signifficant amount of time creating.

arguably not a dupe, but practically another bug about the lack of persistent storage; let's discuss use-cases and potential solutions there

Home screen web apps on iOS and iPadOS already have a carveout. See "Home Screen Web Application Domain Exempt From ITP" here: https://webkit.org/blog/11338/cname-cloaking-and-bounce-tracking-defense/
