1. The extension

What it stores

BangBar saves two things: the custom bangs you create (a short token, a name, and a search URL template) and the list of built-in bangs you have hidden or edited. Both are written with chrome.storage.local, which keeps the data on the device you are using. It is not Chrome Sync storage, so it is not copied to your Google account or to your other computers. Uninstalling the extension deletes it.

What it sends

Nothing. The extension contains no analytics, no telemetry, no error reporting, no advertising, and no remote code. It never contacts a BangBar server, because there isn't one — bang resolution is plain string substitution performed locally in your browser.

What it can see

When you type a bang after pressing ! in Chrome's address bar, Chrome passes that text to the extension so it can show suggestions. That text is used to build a destination URL and is then discarded. It is never stored, logged, or transmitted. BangBar cannot read the pages you visit: it requests no host permissions and injects no content scripts.

Permissions

The extension declares exactly one permission — storage, to save your bangs — plus the omnibox keyword that makes ! work in the address bar. It requests no access to your browsing history, your tabs' contents, your bookmarks, or any website.

Where you end up

Running a bang opens a normal search URL on a third-party site — YouTube, Wikipedia, GitHub, or whichever site the bang points at. That site receives the request as if you had navigated there yourself, and its own privacy policy governs what it does with it. BangBar is not involved in that exchange and learns nothing from it.

2. The website

bangbar.app is a static page with no backend, no accounts, no cookies, and no analytics or tracking scripts. The interactive demo runs entirely in your browser; what you type into it is never sent anywhere.

• Local storage

  One key, bangbar-theme, remembers whether you pinned light or dark mode. It stays in your browser and is not transmitted.

• Hosting (Vercel)

  The site is hosted by Vercel, which processes standard server request logs — IP address, user agent, requested path — to serve the page and protect against abuse. We do not add our own logging on top, and we do not query or retain these logs for any purpose of our own.

• Fonts (Google Fonts)

  The page loads its typefaces from Google Fonts. Your browser therefore requests files from fonts.googleapis.com and fonts.gstatic.com, and Google receives your IP address and user agent as part of that request. No cookie is set by these requests. This affects the website only — the extension uses the fonts already installed on your computer and contacts nobody.

3. The Telegram bot

This section applies only if you choose to message @bangbar_bot to suggest a bang or report a problem. Using BangBar never requires it.

While you are answering the bot's questions, your partial answers are held in temporary storage for about fifteen minutes so the conversation can continue where it left off, along with a counter used for rate limiting. When you confirm a submission, your answers are forwarded as a message to the maintainer's private Telegram chat. There is no submissions database. If you abandon the conversation, the partial session expires on its own.

Telegram itself handles these messages under Telegram's privacy policy, and your Telegram username is visible to the maintainer on any message you send. Please don't put sensitive information in a bug report. The bot reads nothing from the extension and writes nothing back to it.

4. What we never do

• We do not sell, rent, or share personal data with anyone.
• We do not build profiles, run ads, or use tracking pixels.
• We do not log your searches, your bangs, or the sites you visit.
• We do not use your data to train machine-learning models.

5. Your rights

Because the extension holds your data on your own device and we keep no copy, there is no account to export and nothing on our side to delete. You can inspect, edit, or remove every bang from the extension's options page, and uninstalling BangBar erases its storage completely.

If you have sent a message through the Telegram bot and would like it deleted from the maintainer's chat, or you have any other question about your data under the GDPR, the CCPA, or similar laws, write to us at the address below and we will act on it.

6. Children

BangBar is not directed at children under 13 and knowingly collects no personal data from anyone, of any age.

7. Changes

If this policy changes, the effective date at the top of the page changes with it, and the revision is published here. Any change that would broaden what BangBar collects would ship alongside a new extension version and its own Chrome permission prompt — which Chrome shows you before the update installs.
