Cookie policy
Which cookies and browser storage the site uses, which need your permission, and how to change your mind.
Last updated: 2026-10-10. This policy covers cookies and similar technologies (local storage, session storage and IndexedDB), as required by art. 22.2 of Spain's LSSI-CE. Who we are and how we handle personal data is explained in the privacy policy.
TempMV sets no cookies of its own — not even for signing in, which uses local storage instead. The only cookies come from Microsoft Clarity and Google AdSense, and only after you accept them. What the site does use is browser storage on your device, which never travels with a request on its own. The items below are needed for features you ask for, so they are exempt from consent.
Strictly necessary
| Key | Type | Purpose and duration |
|---|---|---|
tempmv.auth.v1, tempmv.auth.v1-code-verifier | Local storage | Your sign-in session (only with an account). Removed when you sign out. |
tempmv.consent.v1 | Local storage | Your answer to the cookie banner. Until you change it. |
tempmv.sync.device, tempmv.sync.origins, tempmv.sync.settingsAt | Local storage | A random device id and timestamps used to sync your account between devices. |
tempmv.siteConfig.v1, tempmv.broadcasts.seen, tempmv.alerts.acked, tempmv.customDistros.v1 | Local storage | A cached copy of the site's settings and of the systems the owner added to the catalog, and which announcements, update notices and alerts you have already seen or acknowledged. |
tempmv.movi.guest.v1 | Local storage | Your Movi guest conversation and its random id (signed out only). Until you clear it or sign in. |
tempmv.session, tempmv.groupLinks.v1, tempmv.api.tryToken, tempmv.staleChunkReload | Session storage | Start-of-visit flag, links between running machines and group machines, an API token you pasted into the docs, and a one-time flag that reloads the page once after an update when part of the old version is gone. Deleted when you close the tab. |
Preferences and your own content
These keep the things you create or choose in the app. They stay on your device until you clear them (if you have an account, some of them are also synced, as the privacy policy explains).
| Key | Type | What it holds |
|---|---|---|
tempmv.settings.v1, tempmv.prefs.v1, tempmv.navTree.v1, tempmv.lastPath, tempmv.moviBanner.hidden, tempmv.admin.tab, tempmv.api.sampleLang | Local / session storage | Settings, layout and the last page you visited. |
tempmv.library.v1, tempmv.networks.v1, tempmv.vnet.active.v1, tempmv.vmjson | Local storage | Machine templates, virtual networks and the JSON editor draft. |
tempmv.learn.v1, tempmv.achievements.v1, tempmv.daily.v1, tempmv.daily.started, tempmv.daily.reminded, tempmv.activity.v1 | Local storage | Course progress, achievements, daily challenge and the local activity log. |
tempmv-shots | IndexedDB | Screenshots you took (50 by default). |
tempmv-disks | IndexedDB | A copy of your persistent disks (only with an account), so they load fast. Wiped when you sign out. |
tempmv.viewAs, tempmv.viewAs.backup | Local storage | Site owner only: a temporary copy of their own data while viewing the site as another account. Removed when they go back. |
Analytics cookies (need your consent)
Microsoft Clarity sets first- and third-party cookies (such as _clck, _clsk, CLID, MUID) to recognise a returning browser and stitch a visit's pages together for heatmaps and session replays. They last from one day up to about a year, as set by Microsoft. They are not strictly necessary: Clarity is only loaded after you accept.
Advertising cookies (need your consent)
Google AdSense sets third-party cookies (such as __gads, __gpi and, on Google's own domains, cookies like IDE) to select ads, limit how often you see the same one, and measure performance, for periods set by Google of up to about 13 months. These are not strictly necessary, so nothing is loaded until you accept. If you decline, the AdSense script is never requested and no advertising cookie is set. Ads only ever appear on reading pages; the app screens carry no advertising at all.
Analytics and advertising are accepted or rejected together, with one choice. Rejecting is as easy as accepting, and the banner only appears on the reading pages.
Other requests that are not cookies
The typefaces are loaded from Google Fonts, and some disk images come from third-party mirrors. These requests set no cookies of ours, but they reveal your IP address to the provider, as the privacy policy explains. Persistent disks are read and saved through our own disk server with your session token in each request; no cookie is involved.
Changing your mind
Use the buttons below to withdraw your consent or to be asked again; the same controls are in Settings → Privacy. After withdrawing, Clarity is told to stop and no new ads are requested; reload the page to unload scripts that were already running, and delete existing cookies in your browser settings if you want them gone at once. Clearing this site's data in your browser resets everything, including your preferences and anything stored only on this device.
