Privacy framework

Mechanical Integrity by Design.

How ProvSeal handles files, permissions and user data with local-first security.

Local-first by design

ProvSeal processes supported media files directly in the local extension environment. Verification and signing workflows are designed to run locally, without uploading your files to a ProvSeal backend.

No cloud uploads On-device processing

File handling

When you select or drop a file into the extension, the file is used only for the requested action: verify, inspect, or sign. ProvSeal does not use your files for advertising, profiling, training, or unrelated analytics.

Extension permissions

ProvSeal requests only the permissions needed to provide its core features:

  • File verification
  • Local signing
  • Page media scan
  • Context menu actions

Limited Use disclosure

The use of information received from extension permissions adheres to applicable store User Data Policy requirements, including Limited Use. User data is used only to provide and improve the extension's single purpose: local C2PA Content Credentials signing, verification and page media analysis.
