You could make your own sort of "encryption algorithm" just so if ever someone gets a glimpse over your seed, they wouldn't be able to steal your coins. Like, probably instead of writing your seed straight on, probably take a look at the word list and list the words above or under your seed words instead. This example is definitely not a good way to do it, but I hope you get the idea.
To safely secured my personal data like mnemonic phrase etc. I created a google docs. And i compressed it through winrar with a strong password and saved to my usd flash drive. Thats how i safely secured my personal data.
This is definitely a bad bad way of doing it.
Thanks for the information Sir. I thought with that method i safely secured my data. So i need an extra careful with my personal data. From now on i will make my own encryption algorithm. Thanks for the i idea Sir. I will keep that in mind always.
