Usually I screenshot the phrase because to check and re-enter it we just open the image and retype it, use a laptop or desktop to make it easier and save it on my hard disk and laptop. Actually, this depends on how each person works, just be careful and save it and don't link your wallet to suspicious sites. It is important to always check your address or seed phrase regularly.
This is one of the WORST ways to keep your Seed. Do not link your Wallet to suspicious websites but have a Screenshot of your Seed? This sounds like a HUGE disaster waiting to happen.
Practice better Seed storage methods. Bots scrapping text off images are a thing. Try writing a post on a popular Internet forum like Reddit containing a digital game code. It will become redeemed in seconds.
