MessageSeal
Encrypt or sign text locally, then share it through another app.
MessageSeal is an iPhone and iPad app for local text protection. It creates signed public identity bundles, shareable MessageSeal1 encrypted bundles, readable signed plaintext with detached verification footers, and Nearby Exchange sessions for local device-to-device identity setup. It keeps private keys on device and pins one Apple-native crypto profile at a time so its identities and protected bundles are not tied only to older public-key designs.
Privacy
Review how MessageSeal handles local storage, sharing through other apps, Nearby Exchange, retention, deletion, and what the app does not collect.
