Cookie Policy
Version 1.0, effective 13 September 2026. This page covers our website at elixirai.io and the Elixir app. It explains what we store on your device, why, and what you can turn off. The Privacy Policy explains what we do with personal data generally; where the two touch, this page is the detail for cookies and similar technologies.
"Cookies" here means cookies and the things that behave like them, including the storage a browser keeps for a website. The rules are the same for all of them.
1. What we use, and what you are asked about
Three kinds. Essential storage, which the service cannot work without and is set as soon as you arrive. Preferences, which remember how you left a page and are written only at the moment you make the choice they record. Analytics, which measures how the site and the app are used and waits until you agree.
You are asked about analytics, and only about analytics. Essential storage needs no question because the service does not work without it, and a preference is written only because you asked for the thing it remembers.
We set no advertising cookies, we do not track you across other people's websites, and we do not use what analytics collects for advertising or pass it to anyone beyond the measurement providers named on our sub-processor page. We ask one question, about analytics, so this page describes one choice rather than a list of switches.
2. Essential storage
Set without asking, because the law allows storage that is strictly necessary to provide a service you asked for, and because the service genuinely does not work without it.
Sign-in: Keeps you signed in as you move between pages, and signs you out when you ask. Set by Supabase, our authentication provider, as cookies whose names begin `sb-`. Lasts for your session and is refreshed while you keep using the service.
New-device check: A security cookie. When you sign in from a device we have not seen, we tell you. This cookie records that the check has already run for this session so it is not repeated on every page. It holds a value issued by our server, cannot be read by scripts, and is discarded when you close the browser.
Your choice on this page: Records whether you agreed to analytics, so we do not ask again. Holds a version and a yes or no, nothing else. Lasts six months.
3. Preferences
Small conveniences the service remembers so it looks the way you left it. They are not essential, and we do not claim they are. Each one is written only at the moment you make the choice it records, inside the app and while you are signed in, which is why they are not part of the question the banner asks. They hold nothing about you and they never leave our own site.
Your light or dark theme is saved to your account rather than to your device, so the Privacy Policy covers it and this page does not.
Your view: Whether a list of dashboards, projects or reports is shown as a grid or a list. Each list keeps its own cookie, named after the page it belongs to, so one does not change another. Lasts a year.
Your filter: Which dashboards you last chose to see, such as all of them or only your own. Named `dash_filter`. Lasts a year.
4. Analytics, only if you agree
We use Google Tag Manager to load two measurement tools, Google Analytics and Matomo. Nothing is loaded and no analytics cookie is set until you agree. If you decline, the tools are never loaded at all, rather than loaded and asked to stay quiet.
If you agree, those tools record which page was viewed, its title, and the address of the page with any customer or project name removed before it is sent, so a record shows that a report page was used without showing whose report it was. Where you are signed in, an account reference is included, which is a random identifier rather than your name or email address. Google Analytics and Matomo set cookies of their own to recognise a returning browser. Google's are typically named with a `_ga` prefix and Matomo's with a `_pk` prefix, and their lifetimes are set by those tools rather than by us, currently up to two years for Google Analytics and thirteen months for Matomo. Both tools also work out your device, browser and rough location, to the level of a country or a city, from the connection you arrive on.
Both companies are listed on our sub-processor page with the country they process in and the safeguard that applies.
5. What we do not do
We set no advertising or profiling cookies, we do not follow you to other websites, and we do not use what analytics collects for advertising or pass it to anyone beyond the measurement providers named on our sub-processor page. We also load no analytics at all on the payment page, so nothing from a third party runs while you are entering card details.
6. One choice, both places
Our website and the app are moving to a shared domain so that one answer covers both: decide on the website and the app will not ask you again, and the reverse. Until that move is finished the two are separate, so you may be asked once on each. Your choice always applies in full to the place you made it.
7. Changing your mind
The banner appears the first time you visit and does not return until your choice expires. To change your answer before then, use the "Cookie choices" link in the footer of either the website or the app, which brings the banner back.
If you withdraw your agreement we stop loading the analytics tools, and we clear the analytics cookies we are able to reach. A page already open may keep a script that was loaded before you changed your mind, so we reload the page for you; cookies set by another company can also be cleared in your browser, which is the surest way to remove everything.
Your browser can block or delete cookies for any site, including ours. Blocking essential storage will stop you signing in. We ask again after six months, or sooner if what we use analytics for changes.
8. Changes to this policy
We publish changes here with a new version number and the date they take effect. A material change is brought to your attention before it applies, as section 15 of the Terms of Service provides; anything else applies when it is published.
