No. Monolith does not have access to your private key or Seed. If you’ve lost these words, you can retrieve them through the app by hitting the ‘Settings’ tab followed by ‘Back up Seed’ under the ‘General’ menu. Please keep a hard copy of your Seed in a safe place (not on your device, in case your device is lost or stolen). Your public key is public and is therefore accessible to everyone on the Ethereum network, including Monolith.
