Cookie Notice
The Delta-V website sets no cookies of its own. It keeps a few small values in your browser’s local storage instead — your advertising consent choice, whether your account is ad-free, and your sign-in session if you created one — and none of those is a cookie or is sent anywhere. Advertising cookies are a separate matter: they come from Google AdSense. In the EEA, the UK and Switzerland you are asked before the first ad is requested and nothing loads until you answer; everywhere else advertising starts with the page and the cookie settings control switches personalisation off the moment you use it. Either way, answering Reject non-essential switches advertising to non-personalised rather than switching the site off, and it takes exactly one press — the same as accepting. Shopify sets its own cookies once you reach its hosted checkout, which is a different site. Last updated 26 August 2026.
STORAGE INVENTORY
What this notice covers
A cookie is a small file a site asks your browser to keep and hand back on every later request. Related technologies do a similar job by other means: local storage, session storage, IndexedDB, and pixels. This notice covers all of them, because what matters is what is stored and why, not which mechanism holds it.
It applies to the Delta-V website. The Delta-V Android app does not use cookies at all — it uses device identifiers, which are described in the Privacy Policy.
One distinction runs through everything below. Local storage is not a cookie. A cookie is attached to every request your browser makes to the domain that set it, which is what makes cookies useful for tracking. A local-storage value sits on your device, is readable only by pages on this domain, and is never attached to anything — code has to deliberately read it and send it, and this site does not.
Strictly necessary cookies
None. Pages are rendered on the server and delivered without session state, so there is no login cookie, no CSRF cookie and no cart cookie to set. If a feature is added that genuinely cannot work without one — a persistent cart is the likely candidate — it will be listed here by name and purpose before it ships.
Your consent choice
When the site needs your answer about advertising, it asks once and then records what you chose, so it does not ask again on every page. That record is a single value in your browser’s local storage holding the answer you gave and when you gave it. It is essential in the strict sense — without it, the only way to honour your choice would be to ask again constantly — and it is stored on your device rather than as a cookie.
The record is treated as expired twelve months after you made it. When that happens the request comes back and you answer again, because a consent given a year ago is not evidence of a preference held today. Clearing site data has the same effect immediately.
Your answer is passed to Google using its consent signals, so Google is told what you allowed rather than being left to assume. Every page starts with those signals set to denied, before any advertising code is allowed to run, and they are only raised once a stored answer — or a choice you have just made — says to raise them.
The ad-free entitlement cache
Owners of Comms Silence or an active Velocity Pass in the Delta-V Android app can sign in to remove ads from the website as well, as described on the ad-free page. Two things are stored in your browser when you do:
- The sign-in session. Firebase Authentication keeps your Google sign-in token in this domain’s local storage or IndexedDB so you are not asked to sign in on every visit. Google also sets its own cookies on its own sign-in domain during the sign-in itself, which is Google’s processing rather than ours.
- The entitlement cache. Whether the signed-in account is ad-free, and the time that was last checked. The site re-checks no more often than every 12 hours. This exists for speed: it means a returning ad-free visitor gets an ad-free page without the sign-in code being loaded at all.
Both are removed when you sign out, and both go when you clear site data for this domain. Neither is a cookie, neither is sent to us, and neither contains your purchase history — the cache holds a yes or a no and a timestamp. What the sign-in reads, and what it does not, is set out in full on the ad-free page.
Other preferences
Nothing else is stored today. No page keeps a preference of its own beyond the consent record and the ad-free cache above. Where one is added later — a selected filter, a collapsed panel, a dismissed notice — it will use local storage rather than a cookie, which means it stays on your device, is never sent to a server, and is cleared whenever you clear site data for this domain.
Analytics
The website runs no analytics product. There is no Google Analytics tag, no third-party measurement script, and no social-network pixel. The only record of your visit is the ordinary server log described in the Privacy Policy, which is not a cookie and does not follow you anywhere.
The Delta-V app is a separate matter: it uses Firebase Analytics, which works from device identifiers rather than cookies.
Advertising cookies
Website advertising is served by Google AdSense. It is the only thing on this site that can set a cookie, and it is the only reason the site asks you anything.
In the EEA, the UK and Switzerland, nothing loads before you answer. The AdSense script is not requested and no advertising cookie is set until a consent choice exists. The request appears on your first visit, as Google’s EU user consent policy requires, and every consent signal stays at denied until you answer it. Accept and reject sit side by side, the same size, one press each. Dismissing the request without choosing records nothing at all — and because nothing was recorded, no advertising loads on that visit and the request returns on the next one.
Everywhere else, advertising starts with the page. Outside those countries the site treats personalised advertising as permitted until you say otherwise, which is the ordinary posture there, so Google may set its advertising cookies on your first visit without asking first. The control is still yours and it is not buried: open cookie settings from the site footer, choose Reject non-essential, and personalisation stops immediately and stays off across visits. Nothing about switching it off is slower or harder than leaving it on.
If you accept, Google may set cookies from its own domains to select an ad, cap how often you see it, measure whether it worked, and detect click fraud, and it may use them to personalise what you are shown. Those cookies are set and read by Google, not by us, and their contents are not available to this site. What Google does with them is described in Google’s advertising technologies notice.
If you reject, advertising runs in non-personalised mode. Ads are chosen from the page you are on rather than from any profile of you, and no profile is built from your visit. Google may still store a limited amount of information for frequency capping, aggregated reporting and fraud prevention — non-personalised means no profiling, not no ad request — and that is the extent of it.
Ads are removed entirely for anyone whose Delta-V account carries Comms Silence or an active Velocity Pass, in which case no AdSense script is loaded and the question of advertising cookies does not arise. See the ad-free page. Advertising is also covered from the data-protection side in the Privacy Policy.
Shopify checkout
Depot product pages are served by us and set nothing. Pressing checkout sends you to Shopify’s hosted checkout on a Shopify domain, where Shopify sets the cookies it needs to hold your cart, run fraud checks and complete the payment. Those cookies belong to that site and are governed by Shopify’s cookie policy. Refusing them means checkout cannot function, which is a Shopify matter rather than one this notice can resolve.
Changing or withdrawing your choice
Your consent choice is not final and withdrawing it is meant to be as easy as giving it. Nothing on the Delta-V website depends on a cookie, so you can refuse the lot without losing a feature.
- Use the cookie settings control in the site footer. It reopens the same two choices with the same weight, and the new answer takes effect immediately — including switching personalised advertising back off, and telling Google so.
- Clear site data for this domain. That removes the stored choice along with any preference, the entitlement cache and the sign-in session, and the consent request appears again on your next visit.
- Turn off ad personalisation at Google Ad Settings, which applies across every site you visit rather than this one alone.
- Block third-party cookies in your browser settings. Every major browser has this control, usually under Privacy or Site settings, and it can be applied to this site alone.
- Use a content blocker, which prevents the advertising script loading in the first place.
- Use the industry opt-out tools: YourAdChoices in the United States, or Your Online Choices in Europe.
On Android, you can also reset or delete your advertising identifier under Settings → Google → Ads, which breaks the link between your device and any advertising profile built from it. The in-app consent answer is changed separately, under Settings → Privacy options inside Delta-V.
Common questions
Does the Delta-V website set cookies?
The Delta-V website sets no cookies of its own. The things it remembers — your advertising consent choice, whether your account is ad-free, and your sign-in session if you created one — are all kept in your browser's local storage on this domain, which is never attached to a request and never leaves your device. Cookies come from two other places: Google AdSense, which serves the ads, and Shopify, once you reach its hosted checkout on a different site. In the European Economic Area, the United Kingdom and Switzerland, no AdSense cookie is set until you have answered the consent request. Elsewhere, advertising runs from your first visit and the cookie settings control switches personalisation off whenever you want it off.
What happens if I reject non-essential cookies?
Ads keep appearing, but they run in non-personalised mode: they are chosen from the page you are on rather than from a profile of you, and no advertising profile is built from your visit. Nothing else on the Delta-V website changes. No page, countdown, article or feature is withheld for rejecting, and rejecting takes exactly one press — the same as accepting.
How do I change my mind later?
Use the cookie settings control in the site footer. It reopens the same two choices and applies the new answer immediately, including switching personalised advertising back off and telling Google so. Clearing site data for this domain also removes the stored choice. Your answer is treated as expired twelve months after you gave it, at which point the request comes back on its own.
Is the ad-free sign-in a cookie?
No. Signing in to check for a Delta-V ad-free purchase stores a Google authentication token and a small cached result in your browser's own storage on this domain, not in a cookie. Google sets its own cookies on Google's sign-in domain during that process, as it does for any Google sign-in. Signing out clears the cached result immediately, and clearing site data removes the rest.
Does the Delta-V Android app use cookies?
No. A native app does not have a cookie jar in the browser sense. It uses device identifiers instead — an advertising identifier for ads, an app instance identifier for analytics, and an installation identifier for crash reports — all of which are described in the Delta-V privacy policy. The app's consent prompt is Google's UMP form, and the answer can be changed under Settings, Privacy options.
