Frequently asked questions
These answers apply to version 0.1.0. Where something does not exist yet, we say so.
Is it really open source?
Yes. It is distributed under the MIT licence and the source is at github.com/girginos/girginosapp.
Do you collect any data?
No. There is no telemetry, no analytics, no account and no identifier assigned to you. The browser makes three requests on its own: the update check, the filter list download and the icons of the sites you visit. All three are described in the privacy policy.
Why does Windows show a warning?
Because the installer is not yet signed with a code signing certificate, SmartScreen warns you on first run. Click More info and then Run anyway to continue. If you want to be sure the file is intact, compare the SHA-256 digest on the download page.
Why is the package 106 MB?
Because Chromium is inside it. Unpacked it comes to 370 MB: the engine binary alone is 235 MB, language files 49 MB, the DirectX shader compiler 24.6 MB, Chromium's licence texts 19.5 MB and ICU data 10.4 MB. All of the code we wrote is 1.5 MB, roughly 0.4% of the package. Chrome's installation is a similar size. This is also only the first install: thanks to the blockmap, updates download only the blocks that changed.
Is it Chromium-based?
Yes, by way of Electron. The rendering engine is Chromium; tab handling, the address bar, the blocker, history, bookmarks, downloads, the permission flow and the entire interface are this project's own code.
How do updates work?
The browser fetches a signed release manifest, verifies the signature with the embedded Ed25519 public key, applies the version and digest gates, compares the sha512 digest of the downloaded package against the signed one, and starts the installation only once you approve it. The full sequence is on the security page.
Can I install extensions?
No. There is no WebExtension support.
Is there a macOS or Linux build?
Not yet. Only the Windows 10/11 (64-bit) package exists.
Is there a private window?
Not yet.
Where is my data kept?
On your own computer, under the %APPDATA%\Girginos Browser\ folder.
Can I turn off the blocker or the updates?
Both can be switched off in Settings. The blocker can also be disabled for an individual site.
Is there an enterprise or bulk deployment option?
Not yet.
