Brushover is a browser extension that lets you draw on top of web pages. Your drawings stay on your own computer. Brushover also has a public ink leaderboard, which needs a little information about how much you draw. This page explains exactly what Brushover stores, what it sends for the leaderboard, and how to delete it.
What Brushover stores on your computer
- The drawings you make: shapes, lines, text, blur boxes, voice notes, and any pictures you add to a drawing.
- The address and title of the page each drawing belongs to (the URL, without anything after a
#), so the right drawing comes back when you open Brushover on that page again, and so the Library can list your drawings by website. - Your ink total: how many metres of lines and shapes you've drawn.
- Your leaderboard player: a random ID, your leaderboard name, and whether you've hidden yourself from the leaderboard.
- Text you highlight on a page: the highlighted words and a few words around them, so the highlight can be found again next time.
- Whether to include your microphone in tab recordings.
A page is only stored once you draw or highlight something on it. Opening Brushover and closing it without doing either stores nothing. Everything is saved in Chrome's extension storage on your computer.
What Brushover sends for the leaderboard
Everyone who draws with Brushover is on the leaderboard at brushover.vercel.app, under a made-up name, unless they hide themselves. To keep your place up to date, Brushover sends updates while you draw. Each update contains only:
- a random player ID, made on your computer when you first draw. It isn't linked to your Google account, your email or your device;
- your leaderboard name, a made-up one like "Teal Otter 417" unless you choose your own;
- how many metres of ink you've drawn since the last update.
Your leaderboard name and ink totals are public on the leaderboard. Your player ID isn't shown to anyone.
Brushover never sends your drawings, the addresses of the pages you draw on, or anything from those pages.
Like any website, the leaderboard server sees your IP address when Brushover connects to it. Brushover uses it for one minute to stop spam, then deletes it. The companies that run the leaderboard for Brushover may keep standard request logs for a short time.
Who handles leaderboard data
- Vercel hosts the leaderboard and this website.
- Upstash runs the leaderboard's database.
They handle the data only to run the leaderboard. Brushover doesn't sell, share or transfer it to anyone else.
How long leaderboard data is kept
- Today's board: deleted 3 days after your last update.
- This week's board: deleted 3 weeks after your last update.
- This month's board: deleted 70 days after your last update.
- The all-time board and your leaderboard name: kept until you hide yourself or remove Brushover.
What Brushover doesn't do
- It doesn't upload your drawings or the addresses of pages you draw on.
- It doesn't collect the content of the pages you visit. It only reads a page when you ask it to, and only on your computer: to find emails, phone numbers, card numbers and keys when you click Auto-redact, to measure an element you point at, to keep text you highlight, and to capture the tab when you save a screenshot, make a bug report or record.
- It has no accounts, analytics or ads, and doesn't track which sites you visit.
- It doesn't sell your data.
When something else leaves your computer
Only when you ask for it:
- When you click Save screenshot, Brushover captures what's visible in that tab (the page with your drawing) and saves it as a PNG on your computer. Brushover doesn't keep it or send it anywhere.
- When you make a bug report, Brushover puts a screenshot and a short report (the page's title and address, your browser and window size, the time) on your clipboard or saves the screenshot, as you choose. Where you paste it is up to you.
- When you copy your highlights, they go to your clipboard.
- When you export a drawing or save it to a file, it goes where you choose, or to your clipboard.
- If you paste or drop a link to a video (for example, from YouTube) into a drawing, the video loads directly from that site, the same way it would in a normal tab.
Recordings and voice notes
- Tab recordings are made in your browser and saved straight to your computer. The tab, its sound and, if you turn it on, your microphone are recorded only while a recording is running. Brushover doesn't upload or keep your recordings.
- Voice notes are recorded from your microphone only while you're recording one, and saved with that page's drawing on your computer. They're never uploaded.
- The first time you record your voice, Chrome asks you to allow the microphone for Brushover.
Permissions and why Brushover needs them
- activeTab and scripting: when you click the Brushover button or press its shortcut, Brushover adds its drawing layer to that one tab, and can take a screenshot of that tab when you click Save screenshot. It can't see or change tabs you haven't opened it on.
- storage and unlimitedStorage: to save your drawings on your computer. Drawings with pictures in them can be bigger than Chrome's standard storage limit.
- offscreen: runs the recorder in the background, for tab recordings (so they keep going while you use the page) and voice notes.
- tabCapture (asked only when you first record the tab): to record the tab you're on. Chrome describes it as "Read and change all your data on all websites", but Brushover only uses it to record the tab you choose, while you're recording.
Your choices and deleting your data
- To change your leaderboard name or leave the leaderboard: open Brushover, open More tools in the dock and choose Ink leaderboard (it's also in the menu), and edit your name or turn off "Show me on the leaderboard". Turning it off deletes your entry and name from every board and stops all updates. Your ink total still counts on your computer.
- To delete one page's drawing (with its blur boxes and voice notes): open Brushover on that page, open the menu in the top right, and choose Reset the canvas. The drawing is removed from storage.
- To delete a highlight: in the dock, open Mark up and choose Highlight text, then click the highlight. When a page has no highlights left, its highlights are removed from storage.
- To delete everything: remove Brushover from Chrome. Its storage on your computer is deleted with it, and Chrome opens a page that deletes your leaderboard entry and name.
