MHTSdigiXR Colour Studio is a no-login design tool. There is no user account, no MHTSdigiXR server that stores your palettes, and no tracking or analytics in the app today. Everything below describes exactly what the web app and its companion Chrome extension do with data on your device.
1. No account, no backend
The studio does not ask you to sign up or log in, and there is no MHTSdigiXR database that receives or stores your colours, palettes, or usage. All product data lives only in your own browser unless you explicitly export or print it.
2. What's stored in your browser (web app)
The web app keeps its working state in your browser's localStorage, scoped to
the site you're visiting it on:
- Your current in-progress palette and your saved palettes.
- A one-time "package tier" flag (starter/custom) if MHTSdigiXR sent you a link containing
a
?tier=parameter — this only toggles which features your link unlocks and never leaves your browser. - If you use the Graphic Library panel, the Unsplash Access Key you paste in (stored locally so it can be reused on later visits — see §5).
None of this is transmitted to MHTSdigiXR. Clearing your browser's site data for this app, or using a private/incognito window, removes it.
3. Exports and printing
"Export palette" (JSON/CSS/Tailwind-style/CSV) and "Print colour cards / PDF" are generated entirely inside your browser and saved or printed directly from your device. Nothing you export or print is uploaded to MHTSdigiXR or any third party as part of that action.
4. Chrome extension — sampling and storage
The companion Chrome extension (when installed) keeps its own saved palettes in
chrome.storage.local, a separate store from the web app's localStorage.
Colour sampling only runs when you deliberately click the extension icon and then click a
point on the page you're looking at — it reads the computed background colour (or, for a
transparent element, the nearest solid colour behind it, or a gradient's first colour stop) at
that single point, and only after that explicit action. Sampled colours stay in the
extension's local storage unless you choose to sync or export them; they are never sent to a
server.
5. Syncing between the web app and the extension
Syncing is manual only — it happens when you click "Sync extension" in the web app, never automatically or in the background. It works entirely inside your own browser, via the page asking the extension (through the page's content script) to merge palettes already stored locally on both sides; this never leaves your device or goes over the network.
6. Third-party services this app talks to
Two features make requests to third-party services directly from your browser, independent of MHTSdigiXR:
- Google Fonts (Typography Studio): selecting a font loads it from Google's font CDN, the same way any website using Google Fonts does. Google's own privacy policy governs that request.
- Unsplash (Graphic Library): if you paste in an Unsplash Access Key and
search for photos, your search keywords and that key are sent directly from your browser to
Unsplash's API (
api.unsplash.com) to fetch results and (per Unsplash's API Guidelines) to register that a photo was selected. MHTSdigiXR does not see or store these requests; Unsplash's own privacy policy and API terms govern them. The Access Key itself is stored only in your browser'slocalStorageand is never committed to MHTSdigiXR's codebase.
7. Cookies and analytics
The app does not set tracking cookies and does not currently run any analytics or advertising scripts.
8. Changes to this notice
If local storage, export behaviour, extension sampling, or sync behaviour changes, this notice will be updated to match before that change ships.
