-### Encryption Mode
-
-Use the `--encryption-mode` flag to control how SeedPass derives the key used to
-encrypt your vault. Valid values are:
-
-- `seed-only` – default mode that derives the vault key solely from your BIP-85
-  seed.
-- `seed+pw` – combines the seed with your master password for key derivation.
-- `pw-only` – derives the key from your password alone.
-
-You can set this option when launching the application:
-
-```bash
-python src/main.py --encryption-mode seed+pw
-```
-
-To make the choice persistent, add it to `~/.seedpass/config.toml`:
-
-```toml
-encryption_mode = "seed+pw"
-```
-
-SeedPass will read this value on startup and use the specified mode by default.

 **Options:**
 - `--file` (`-F`): The destination file path for the exported data. If omitted, the export

-- `--mode` (`-M`): Choose the encryption mode for the exported file. Valid values are:

-# Combine seed and master password for the export key
-seedpass export --mode seed+pw --file "backup.json"
-# Derive the key solely from your password

-seedpass export --mode plaintext --file "backup.json"
