Bianex Browser Privacy Policy · Version 2.0 · Effective 25 October 2026
The short version. Bianex has no accounts, no analytics, no advertising SDKs and no servers that receive your browsing. Your history, bookmarks, passwords, tabs and settings stay on your device. A browser still has to connect to the internet: Section 5 lists every connection Bianex makes on its own, what each one reveals, and how to turn off the optional ones.
Bianex Browser ("Bianex", "the App") is made by BIAN ("BIAN", "we", "us", "our"). This Privacy Policy explains what happens to information when you use Bianex on Windows (including the portable form, Bianex Go) and on Android, and when you visit Bianex's websites (bianexbrowser.com and biantech.org).
It should be read together with the Bianex Terms of Use, which govern your use of the App. If you do not agree with this Policy, please do not use the App and uninstall it.
We do not collect, receive or keep on our systems:
The App keeps the following on your device so that it can work. We have no access to it.
Private tabs and Ghost Mode do not add to your history. On Windows, the portable form keeps all of this in the BianexData folder beside the App.
Data on your device is protected by your device. Use a screen lock, keep your system updated and protect your device from malware. We cannot recover data you lose, and we are not responsible for access to your data through your device being lost, shared, compromised or infected (see the Terms of Use).
Every connection to a server reveals your IP address and ordinary connection details (such as the time and the software making the request) to that server. That is how the internet works for every app. The App attaches no account or identifier of you to the requests below. Each server is run under its operator's own terms and privacy policy.
When you open a page, the App connects to that website and to whatever the page loads, except what Bianex blocks. Websites may collect information under their own policies. Pages are shown by your system's browser engine: Microsoft Edge WebView2 on Windows and Android System WebView on Android, components of Microsoft and Google that may send their own diagnostic data as your system settings allow. On Windows, Bianex turns off Microsoft SmartScreen inside WebView2, so the addresses you visit are not sent to Microsoft for checking.
The App downloads public filter lists from their independent publishers: on Windows each time it starts (24 lists, from easylist.to, secure.fanboy.co.nz, filters.adtidy.org, raw.githubusercontent.com, pgl.yoyo.org, someonewhocares.org, malware-filter.gitlab.io and i-dont-care-about-cookies.eu), on Android about once a day (4 lists, from filters.adtidy.org, easylist.to and pgl.yoyo.org). Only the lists are fetched; nothing about your browsing is sent. Safe Browsing then checks addresses on your device against these lists; no address is sent anywhere to be checked.
The App downloads a small configuration file, and on Android a curated filter pack, from bianex.biantech.org. Both are signed by us and ignored if the signature does not match. They carry safety notices, a maintenance switch, minimum versions (see Section 7) and filter updates, and contain nothing about you. They are hosted on GitHub Pages, whose operator may keep ordinary request logs under its own policy.
On Windows the App checks bianexbrowser.com for a new version when it starts and when you ask, and downloads an update only if you accept it; an update is installed only if it is signed with our key. On Android, updates come through Google Play under Google's terms.
While you type in the address bar, the App can ask your chosen search engine for suggestions, sending what you have typed so far to that search engine. This is on by default and can be turned off in Settings. On Android, suggestions come only from your own history and bookmarks.
To show a site's icon in Favourites and on the new tab, the App fetches the icon from that site itself. No third-party icon service is used. On Android, the icon a page provides while you visit it is used.
To show Reading Mode, a link preview or a summary, the App fetches the page again from its website. The summary is made on your device.
Translating a page opens it through Google Translate, which receives the page's address and content under Google's privacy policy.
To show the picture of what is playing in the island and the media notification, the App may fetch the picture the page names, from the server the page names.
If you turn on DNS-over-HTTPS in Settings, the names of the sites you visit are looked up through Cloudflare's resolver (cloudflare-dns.com) instead of your network's.
On Android the App asks for these permissions:
| Permission | What it is for |
|---|---|
| Internet, network state | Loading pages and the downloads in Section 5; noticing when you are offline. |
| Notifications | Download progress and media controls. You can refuse it. |
| Foreground service (media playback, data sync), wake lock | Keeping playback and downloads going while the App is in the background. |
| Camera | The QR code scanner, only while it is open. Pictures are read on the device to find the code and are never saved or sent. |
On Windows the App needs no special permissions. On both, a website may ask to use your camera, microphone, location or notifications; Bianex asks you before a site gets it, and you can withdraw it (on Windows, in each site's settings).
Through the signed configuration in Section 5.3 we may show a safety notice, require an update, place the App or a feature in maintenance, or stop a version that has a serious problem from running. We do this to protect users and fix defects. The App ignores configuration that is not signed by us.
We design the App to keep your data on your device and to protect it there: passwords in your system's credential store or encrypted with its keystore, HTTPS with certificate checks for the App's own connections, signed updates and configuration, websites kept out of the App's own controls, and encrypted backups (a backup file is encrypted with a passphrase you choose; we cannot open it or recover a lost passphrase).
No software or method of storage or transmission is completely secure. We fix the problems we find and those reported to us, but we cannot guarantee that the App, your device or the websites you visit are free of vulnerabilities.
Laws such as the EU and UK GDPR, the California Consumer Privacy Act (CCPA/CPRA) and India's Digital Personal Data Protection Act 2023 give you rights over personal data that an organisation holds about you. Because we hold none of your browsing data, these rights are met by the controls above on your own device. For anything we do hold (an email you sent us), contact us (Section 11). We do not sell or share personal information, as those words are used in the CCPA.
Bianex is a general-purpose browser and is not directed to children. You must be at least 13, or older where the law where you live requires it, to use it; younger users need a parent or guardian to agree to these terms and to supervise them. We do not knowingly collect personal information from anyone, including children.
If you email us, we receive your email address and whatever you send, and use them only to answer you and to fix what you report. We keep them only as long as needed for that, and no longer than 24 months unless the law requires otherwise.
If you ask to join the waitlist or to hear product news (the Waitlist on bianexbrowser.com opens your own email app with a message to us), we keep your email address for that alone, send only occasional news about Bianex, never pass it to anyone, and delete it when you ask: reply to any message or write to us at any time.
We aim to answer within 30 days. We may ask you to confirm details before acting on a request.
bianexbrowser.com and biantech.org are static websites hosted on GitHub Pages, which receives your IP address and request details under GitHub's own privacy statement. Neither site uses cookies, analytics or advertising.
Links to other sites are governed by those sites' own policies.
Websites, filter-list publishers, search engines, translation, payment and blockchain services, GitHub, Google and Microsoft act under their own terms and privacy policies, which we do not control. Bianex's protections reduce tracking by third parties but cannot remove it entirely.
If we change this Policy, we will update the version and date above. If the change is material, the App will show you the new Policy and ask you to agree to it before you continue. Earlier versions are available on request.
Warranties, liability, indemnity, governing law and how disputes are resolved are set out in the Bianex Terms of Use, which apply to this Policy too. Nothing in this Policy limits rights you have under the law where you live that cannot be limited by agreement.
