Privacy policy
The short version
Your videos never leave your device. colorgrade.video is a page that grades footage inside your own browser, so there is no upload step and no copy of your clip on any server. We do measure how the site is used, in the ways set out below, and the one measurement that uses cookies can be switched off in two clicks.
Your video, reference images and LUTs
When you open a clip, your browser reads it from your disk or photo library and decodes it locally. Each frame is graded by your device’s graphics chip (or its processor if WebGL2 isn’t available), encoded again and saved back to your device or passed to your phone’s share sheet. Auto colour and Match colours analyse a few small frames to measure colour; those measurements are calculated and kept on your device. The same is true of a reference picture you choose for matching and of any .cube or .3dl file you import: they are read by the page and go nowhere else. No pixels, sound, file names, metadata or colour measurements are sent to colorgrade.video or to any other party.
What is kept in your browser
The site uses your browser’s own storage so your work survives a refresh:
- IndexedDB: the video you have open and the state of the editor, so a reload or a crashed tab can pick up where you left off; an imported LUT, so it comes back after a reload; and temporary pieces of an export while it is being rendered, which are cleared away afterwards.
- Recent videos: the latest graded exports you made (up to 24) are kept on this device so you can download them again later, until you remove them or newer ones replace them.
- Local storage: your favourite looks
(
colorgrade-video:favourite-looks), the looks you used recently, the looks you saved with Save as my look (colorgrade-video:my-looks), a grade you copied with Copy grade (colorgrade-video:clipboard), your light or dark theme (vt-theme) and your analytics choice (vt-consent). - Your clipboard: where the browser allows it, Copy grade also places the grade on your system clipboard as plain numbers in JSON, so you can paste it elsewhere. It holds slider values only, never any part of the picture.
All of this stays until you remove it. Clearing this site’s data in your browser settings deletes everything listed above in one go, including your saved looks.
Requests to other sites
One situation makes the tool fetch code from elsewhere: if your browser can’t decode a file’s format, it downloads the open-source ffmpeg.wasm converter from unpkg.com and converts the video on your device. Like any web request, that download shows unpkg.com your IP address. Your video is never included.
Hosting
Cloudflare hosts and delivers the site. Its servers handle standard connection details, such as your IP address, browser user agent and the page requested, in order to serve pages and block attacks. The legal basis is legitimate interests (Article 6(1)(f) of the UK GDPR and the GDPR), since the site cannot be offered securely without it. See Cloudflare’s privacy policy for how it treats that data.
Visit statistics
Cloudflare Web Analytics and Ahrefs Web Analytics may be used to count page views, referring sites and approximate country and device type. Neither sets cookies, and both report totals rather than individual visitors.
Google Analytics 4, loaded through Google Tag Manager, shows us which looks, controls and guides people actually use, so we know what to build next. It records page views and product events, for example a video being opened, a look or control being chosen (identified by its internal ID), or an export finishing, with rough figures such as clip length or a file-size band. A random ID in a first-party cookie ties those events to one browser. Google Analytics never receives your video, a frame, the sound, a file or LUT name, a name you typed for a saved look, or any colour measured from the picture. Advertising features and Google signals are off, and data is kept for 14 months. Google may process it in the United States under the EU-US Data Privacy Framework; read Google’s privacy policy and how Google uses information from sites or apps that use its services for details.
We rely on legitimate interests in understanding and improving the site (Article 6(1)(f)). For the cookie itself, PECR (the UK’s Privacy and Electronic Communications Regulations) now has a statistical-purposes exception, added by the Data (Use and Access) Act 2025: a site may set a cookie purely to learn how its service is used and improve it, provided it tells you and lets you object. Visitors from the European Economic Area and Switzerland start with analytics storage turned off, so no analytics cookie is set for them.
Cookies and switching analytics off
The site sets no advertising cookies. The only cookies are Google Analytics’
_ga and _ga_*, which can last up to two years. Your first visit
shows a short notice about them with an OK button that simply dismisses it.
To object, open Cookie settings at the foot of any page and choose
Turn off analytics; this browser remembers the choice and analytics stay off
on later visits until you pick Turn analytics on. If your browser sends a
Global Privacy Control signal, we treat it
as an objection and the notice never appears. We show no ads and never sell personal data.
Who runs colorgrade.video
colorgrade.video is an independent, self-funded project. There are no accounts and no sign-in, and since your footage never reaches us, we hold no file, profile or history belonging to you.
Your rights
Under data protection law you can ask to see, correct or erase personal data, restrict or object to how it is used, take a portable copy, and complain to a supervisory authority (in the UK, the Information Commissioner’s Office). Because the tool keeps your work in your own browser, you can exercise most of these yourself: clearing the site’s data erases it, and Cookie settings ends analytics collection. For data Google holds, its privacy policy explains the further controls it offers.
Changes to this page
If the way colorgrade.video handles data changes, this page changes in the same release and the date at the top is updated.
