ShareProof – Blur & Hide Sensitive Data for Screen Sharing

Blur, redact or scramble sensitive data before you share your screen, record a demo or take a screenshot. Runs in your browser.

ShareProof hides sensitive data on any web page before you share your screen, record a demo or take a screenshot. Scramble text into look-alike gibberish, blur it, or cover it with black bars. Photos, videos and charts are hidden too. One click puts everything back. No account needed. Runs entirely in your browser; nothing it reads ever leaves your device. THREE WAYS TO HIDE • Scramble: every word becomes look-alike gibberish. Letters keep their case and roughly their width, and every digit becomes an X, so €84,210.50 reads €XX,XXX.XX. A screenshot still looks like your product, and no fake figure can pass for a real one. • Blur: the text is scrambled first, then blurred. Sharpen the screenshot and you find gibberish, not the real text. • Redact: black bars over the text, with scrambled text underneath too. • In every style, photos, videos, canvas drawings, charts and background images are hidden: blurred, or black in Redact. Icons under 24 px stay sharp, so buttons and menus still make sense. • Choose the style in the popup. ShareProof remembers it, and the keyboard shortcuts use it too. THE WHOLE PAGE OR JUST SOME PARTS • Hide the whole page: every word and picture at once: headings, tables, buttons, even tooltips, placeholders and the tab title. It keeps up as the page changes, so new messages, feed items and screens in single-page apps arrive hidden too. • Pick elements: hover the page and a ring shows what a click would hide. Click a customer’s name, a revenue card or a whole sidebar, and only that part is hidden. The rest stays readable, so your demo still makes sense. • Show parts again: on a hidden page, click a part with the picker and only that part shows, such as the row you are talking about. Click it again to hide it again. • Mix styles: the picker has a tool for each style (keys 1, 2 and 3). Blur a chart, redact an IBAN and scramble the rest. A click on a part hidden in another style switches it to the tool you hold. • Undo and Unpick all are one click away in the picker’s toolbar. • Keyboard shortcuts: Alt+Shift+S hides or restores the whole page in your style and Alt+Shift+E starts picking (Option+Shift on a Mac; on a Chromebook, Alt+Shift+H and Alt+Shift+E), without opening the popup. Change the keys in chrome://extensions/shortcuts. SAFER THAN A PLAIN BLUR • A plain blur leaves the real text under it, and blurred text can sometimes be read back. ShareProof blurs text it has already scrambled, so there is nothing real underneath to recover. Its black bars cover scrambled text too. • Scrambled text keeps the page looking like itself, minus the real data, for when a blur or a black box would draw the eye. • Text fields and rich editors get a hidden copy drawn on top. ShareProof never writes into them, so nothing you type, and nothing the app saves, changes. • Restores in one click. Click Restore page (or press the shortcut) and everything comes back; going to another site or closing the tab ends it too. MADE FOR • Screen sharing and live demos: a demo mode for any web app. Show the real product on a call without showing real customers, salaries or inboxes. • Screenshots for docs and tickets: hide sensitive data in screenshots of a bug, a how-to or a changelog, without retouching anything. • Recording tutorials and videos: whole-page hiding keeps up as you click through, so nothing slips into a frame. • Sales and support on real accounts: walk a prospect through a live workspace and keep other people’s data private. PRIVATE BY DESIGN • The content ShareProof hides never leaves your device. It has no servers to send it to, no analytics and no account. • Originals are kept in the tab’s memory only so they can be put back. They stay there until you reload the page, leave it or close the tab. • It saves one setting on your device, the hiding style you chose. No page content, no browsing history. • Three permissions, activeTab, scripting and storage, nothing else. It can touch a page only after you click its icon or press one of its shortcuts on that tab, and it asks for no access to any site. GOOD TO KNOW • It changes only what your browser shows you. Nothing is sent to the site, and form fields and editors are never written to. • It hides what is on the page, not the address bar, other tabs or browser notifications. • Icons under 24 px stay sharp. The tab title, tooltips and placeholders are scrambled in every style, never blurred or covered with bars. • Whole-page hiding stays on while the tab stays on the same site, through links, reloads and back and forward. The same site means the exact address: a subdomain, such as app.example.com after example.com, counts as another site, and its pages show their real content. Pages you open by typing in the address bar may open unhidden; check before sharing. Links you open in a new tab aren’t hidden. • Frames embedded from other sites, such as chat widgets, videos or ads, stay as they are, text and pictures: Chrome only lets the extension into the site you clicked it on. The popup tells you how many of those frames are visible, so take a look before you share. • A part you hide or show follows its element, not what is in it. In a long list that reuses its rows as you scroll, a row you picked hides or shows whatever record moves into it, and the record you picked can appear in another row as it is. If the page replaces the element itself, the pick ends there: a part you hid on a readable page shows, and a part you showed is hidden again. Scroll with care. • Chrome does not let any extension run on its own pages (like settings or new tab), its error pages, other extensions’ pages, the Chrome Web Store or the built-in PDF viewer. There, the popup explains why the buttons are off. Local files work only if you turn on “Allow access to file URLs” for ShareProof in Chrome’s extension settings. • Text a site’s stylesheet adds to the page (CSS content) stays readable. A few kinds of pictures stay sharp too: ones a stylesheet draws as decoration (before and after elements, list bullets, borders, masks and content images), pictures in an object or embed element, and backgrounds that appear only through a style state such as hover. • Letters in a few scripts it does not cover yet, such as Armenian, Georgian or Tamil, stay readable. • Some apps turn text into a field when you click it. Restore before editing there, or the app could save the scrambled text. • Rarely, text the page copied while hidden stays scrambled after restoring; reload to be sure. • A screenshot still shows the length and shape of each line. Scrambled text also shows capitals, punctuation and symbols, and how wide each word is in the page’s font. With a list of likely names and that font, someone could often tell which name a short scrambled one is. Identical text in the same font scrambles identically on the same page. The letters themselves come from a secret key that exists only in that page’s memory. Made by Magentix Studio.
