Not the safest Idea but I store my seed on the cloud but not just as simply. I always place two random words at fixed word count. I just remember the two counts, never the words and omit those two words while recovering my wallet. There are risks involved but this way, it's much difficult for anyone to crack open my address even though they find some or most of the info.
I have done similar things with private keys. Just two random characters would make it amazingly hard to crack even if they found the keys. For a large amount, I too would recommend a hardware wallet as it provides an extra level of security.
