What
we know,
and don’t.

• *storage: This extension uses session storage to temporarily hold the number that a user highlights and right-clicks on a webpage. This allows the background script to securely pass the selected number to the extension popup as soon as it is opened, ensuring a seamless conversion experience. No data is stored persistently or tracked across sessions. • contextMenus: We require context menu permission to add a "Convert number with BitLens" option to the browser's right-click menu. This is a core feature that allows developers to quickly highlight hexadecimal, binary, or decimal values on any webpage and send them directly to the extension for instant conversion and analysis without needing to manually copy and paste. • clipboardWrite: This permission is necessary to allow users to quickly copy the converted results (such as binary strings, hex values, ASCII codes, or IEEE 754 float representations) directly from the extension's interface to their clipboard with a single click.

BitLens operates entirely locally on your machine by design. No page content, highlighted text, browsing history, conversion data, or personal information is ever transmitted to external servers. All processing, including number base conversions and bitwise operations, happens directly within your browser, guaranteeing absolute privacy and zero tracking.

The extension only requests permissions necessary for functionality: accessing SoundCloud pages and downloading files to your device. No background processes or unnecessary access.

We do not collect, store, or transmit any personal data. All downloads are processed locally on your device with zero server interaction.

storage: Saves optional user settings (e.g. preferred output format) to chrome.storage.local so they persist between sessions. No hash inputs, outputs, or file contents are ever stored.

contextMenus: Adds a "Hash this text" submenu to the browser right-click menu when text is selected on any page. Lets users identify or hash selected text without opening the popup manually.

clipboardRead: Used once when the popup opens to check whether the clipboard contains a string that looks like a hash. If it does, the identifier pre-fills automatically. This behaviour can be disabled in settings. The clipboard content is never transmitted anywhere.

clipboardWrite: Allows one-click copying of hash outputs, Hashcat mode numbers, and John the Ripper format strings directly to the clipboard.

HashLens operates entirely locally. Hash inputs, text inputs, and file contents are processed in your browser using the @noble/hashes cryptographic library and never transmitted to any server. No browsing history, page content, clipboard data, or personal information is collected, stored remotely, or shared with third parties. The only data optionally written to storage is your UI preferences (output format selection), which stays on your device. File hashing for the Verifier runs in a dedicated browser tab using chunked streaming so large files can be processed without interruption — the file bytes never leave your machine.

QuickNote requests only what it needs to work:

• storage — saves your highlights and notes directly in your browser. Nothing leaves your device without your permission.
• activeTab — reads the current page only at the exact moment you highlight text. The extension has no background activity and cannot access other tabs.
• contextMenus — adds a "Highlight" option to your right-click menu so you can save highlights without using the floating toolbar.

Your highlights and notes are stored locally in your browser by default — no account or internet connection required.

If you choose to sign in, your data syncs to a private cloud account that only you can access. Nothing is shared, sold, or used for any purpose beyond showing you your own highlights.

storage — saves your timer settings, focus session state, and blocked site list directly in your browser. Everything stays on your device.

alarms — schedules a single silent alarm at the exact moment your focus or break session ends. Used only to trigger the session transition — no background polling, no tracking.

notifications — shows a brief alert when a session ends so you know to take a break or get back to work. Only fires if you have notifications enabled in settings.

declarativeNetRequest — applies your blocked site list using Chrome's built-in blocking engine. The extension never reads, intercepts, or inspects the content of any web page — it only prevents navigation to hostnames you have explicitly added.

declarativeNetRequestFeedback — allows the extension to read back which blocking rules are currently active, so your block list in the popup stays in sync with what Chrome is actually enforcing.

Access to all URLs — required by Chrome's blocking API so that rules can apply to any website you choose to block. The extension does not visit, read, or collect data from any website.

All data — your settings, session state, and blocked site list — is stored locally in your browser only. No account is required and no internet connection is used.

StartSmall does not collect, transmit, or share any personal data, browsing history, or usage analytics. Nothing is sold, shared, or used for any purpose other than running your focus sessions on your own device.
