android html google-chrome storage web-sql

So I am writing a web app that needs to store ~40MB of offline data in a offline Web SQL database. It needs to work in Chrome (desktop), Safari (desktop and mobile) and android's browser. Now I know that Web SQL is supported in these browsers and I know since which versions but i need to know how much storage is allowed. Safari desktop supports 500MB of database storage. Safari mobile supports 50MB of database storage.

However I have spent literally hours searching everywhere to find out what space chrome desktop supports and what the android browser supports but cannot find anything concrete. One place noted a hard 5MB limit for chrome desktop while another quoted a 25MB limit for chrome desktop (without using a chrome extension). One source for android's browser noted a 15MB limit another noted a 5MB limit. Can anyone point me to somewhere that states what the actual hard limits on Web SQL storage are for android and chrome??

See this link for Google Chrome:

Default is 5MB, but you can switch the unlimitedStorage property

For Android if found this thread that might be helpful: SQLite database maximum storage capacity
