What to expect

An estimate based on declarations and metadata, not a rights certificate or legal clearance. Verify every finding with the original source and rights holder. Missing information never means free to use. Authors and copyright holders may differ. Files are analyzed locally; links are downloaded directly from their source. Browser input is limited to 32 MiB. Archives are bounded and scans can be incomplete.

Do my files leave my device?

No. Thanks to advanced file-processing technology, your files are processed directly on your device, inside your browser. OneKit does not receive your input files or results. Required public processing libraries may download when you first use the tool.
