Diarium is the only thing I’ve found that actually fits the bill, where there is cross platform support and self hosted E2EE.
Unfortunately, Diarium also reduces image quality significantly, even with their ‘higher quality’ setting. My Day One diary export is 90% larger than the data store Diarium syncs to webdav, the loss of fidelity is especially obvious when looking at screenshots.
