PhotonFile will still send this Relay transfer over TLS, but the file will not get the extra client-side encryption layer before it enters the live relay.
Use this compatibility mode only when your recipient needs a browser with incomplete native file API support, such as Safari, Firefox or Brave.
For the strongest Relay privacy posture, keep end-to-end client-side encryption enabled or use PhotonFile Desktop.
For persistent end-to-end client-side encrypted storage, sharing, and Secure Inbox workflows, use Photon Vault.
