In your cloud?? No.
Discussion
so you would rather trust a device that will fail at any given time or can be lost?
I never said that, just done store your seed in the cloud dumbo.
You are right. I meant "Your Cloud"
Also not good.
Why? There are good proven self-hosted cloud solutions
So many good ways to store a seed & you choose the one easiest to fuck up & with many potholes.
Tell me what is wrong with Nextcloud,OwnCloud, and SyncThing on a technical level

You found the solution. I would not trust their encryption software though.
