Common questions

Do you store my .env files?

No. Every browser tool runs entirely in your browser — your files never leave the tab. When you share via the Envy CLI, the file is encrypted with AES-256-GCM before it leaves your machine, and our servers only store ciphertext they cannot read.

Is this free?
