No network, by design
The hosted app at scrubbr.pro makes zero file-bearing network requests; even the PDF engine worker, fonts, and character maps are bundled locally. The self-hosted build goes further: it ships as static files you host internally, with Pro features unlocked and no licensing calls, so it can run on an air-gapped network.
The same guarantees, offline
- True redaction: marked pages are rebuilt from a flattened raster.
- Verification: the output is re-parsed to confirm no recoverable text under the boxes.
- Proof certificate: a record with the file hash, timestamp, and result.
Frequently asked questions
How do I run it air-gapped?
The self-hosted license includes a static build you host on your own infrastructure. It has no outbound network calls, so it runs on an isolated network.
Does the hosted version phone home?
No. It makes no file-bearing requests at all, which you can confirm in your network tab. The only network calls it can make carry a license key or purchase intent, never your file.
