The extension does not collect data for the developer or third parties and does not transmit data to external services. Translation uses bundled dictionaries without analytics, tracking or external translation APIs.

Your chosen language is saved in browser storage. Optional unknown-string diagnostics are disabled by default. If enabled, they store interface text and normalized page routes locally. You can clear them or manually export a JSON file. The extension does not read form input values for diagnostics. Its filtering is heuristic, so review exported files before sharing them. Nothing is uploaded automatically.
