I've seen the term ozonoide now and then, both in german and english texts.

It was used for the the primary, as well as for the secondary ozonide. Interestingly, throughout these texts, you'll find this form only once or twice while the same authors mostly use the term ozonide!

While I'm roughly familiar with the Criegee mechanism, I'm not an expert on ozonolysis. Nevertheless, I'd dare to say there's no difference there's no difference between these terms (at least, there seemingly was none for the authors) and I'd recommend to stay with the established term ozonide.
