A tool running in your browser can still send network requests or load third-party code. Before entering sensitive material, check where processing occurs, what data is retained, and whether the service discloses uploads or analytics. Try the workflow with disposable sample data first.
An offline test can show that one operation works without a current connection, but it does not prove that input was never transmitted in an earlier session. For confidential files, credentials, or customer records, use an approved tool whose data path you have verified. Never paste live passwords or private keys into an unverified utility. Evaluate each Akousa tool by its actual behavior rather than assuming all tools share one privacy model.
