# Cookie Policy and Browser Storage Source: https://nerix.ai/legal/cookies Cookie policy # Cookie policy This page lists everything nerix.ai keeps in your browser. It is short, because this website sets no cookies of its own. Last updated 26 October 2026 ## 01 On this website (nerix.ai) This website sets no cookies of its own. It stores two items in your browser's localStorage, and one more in its sessionStorage if you use the Ask nerix assistant, on your device only. They are not cookies, and they are never sent to us or to anyone else. When you are signed in to the product, the website also reads the product's signed-in hint (below) to show "Open the app" instead of "Sign in". Item nerix-consent Category Strictly necessary Purpose Records which optional categories you accepted or refused, and when you chose. Lifetime Until you change it or clear this site's data in your browser Item nerix-theme Category Strictly necessary Purpose Remembers your light or dark choice so the page looks the same on your next visit. Lifetime Until you change it or clear this site's data in your browser Item nerix-assistant Category Strictly necessary, only if you use the Ask nerix assistant Purpose Kept in this browser tab's sessionStorage, so the assistant's conversation, its session code for the free chat and whether its panel is open follow you from page to page and survive a refresh. It stays on your device. Lifetime Until you close the tab or start a new conversation | Item | Category | Purpose | Lifetime | | `nerix-consent` | Strictly necessary | Records which optional categories you accepted or refused, and when you chose. | Until you change it or clear this site's data in your browser | | `nerix-theme` | Strictly necessary | Remembers your light or dark choice so the page looks the same on your next visit. | Until you change it or clear this site's data in your browser | | `nerix-assistant` | Strictly necessary, only if you use the Ask nerix assistant | Kept in this browser tab's sessionStorage, so the assistant's conversation, its session code for the free chat and whether its panel is open follow you from page to page and survive a refresh. It stays on your device. | Until you close the tab or start a new conversation | Your language is part of the address (pages in other languages live under their own path, like /nl or /ar), so no language cookie is needed. ## 02 Optional categories Three optional categories exist in the cookie settings: preferences, analytics and marketing. Only analytics is in use, and it keeps something in your browser only after you say yes. Without a yes, our visitor counter still counts the visit but stores nothing on your device (the privacy policy explains how). Preferences and marketing are not in use: nothing in them is stored, loaded or sent. Item _an_vid Category Analytics, only with your yes Purpose A random number in your browser's localStorage, so our own visitor counter (Respiresoft analytics, on our server in France) can tell a returning visit from a new one. It records the page, the site that sent you, your browser and device type and your country, never your address, and is used only for statistics, never for advertising or profiling. Lifetime Until you withdraw your yes or clear this site's data; withdrawing removes it | Item | Category | Purpose | Lifetime | | `_an_vid` | Analytics, only with your yes | A random number in your browser's localStorage, so our own visitor counter (Respiresoft analytics, on our server in France) can tell a returning visit from a new one.

Cookie nerix_session Category Strictly necessary Purpose Keeps you signed in to your workspace. Lifetime 14 days, or until you sign out Cookie nerix_csrf Category Strictly necessary Purpose Stops another website from sending forms in your name. Lifetime 1 year Cookie nerix_signed_in Category Strictly necessary Purpose Tells nerix.ai that you are signed in, so it shows "Open the app" and fills templates in your workspace. It holds only the value 1, nothing that identifies you. Lifetime 14 days; removed when you sign out | Cookie | Category | Purpose | Lifetime | | `nerix_session` | Strictly necessary | Keeps you signed in to your workspace. | 14 days, or until you sign out | | `nerix_csrf` | Strictly necessary | Stops another website from sending forms in your name. | 1 year | | `nerix_signed_in` | Strictly necessary | Tells nerix.ai that you are signed in, so it shows "Open the app" and fills templates in your workspace. It holds only the value 1, nothing that identifies you. | 14 days; removed when you sign out | The app also keeps a few things in your browser's storage, on your device only: drafts you have not sent yet, the size of its panels and which menus are open, the model and microphone you chose last, and, in the phone app, your sign-in. No analytics or marketing cookies exist today. If that ever changes, this page and the consent banner change first, and nothing optional is set before you agree. ## 04 Change or withdraw your choice You can change or withdraw your consent at any time: every page has "Cookie settings" in the footer, which reopens the same panel you saw on your first visit. Refusing is as easy as accepting. You can also remove these items by clearing this site's data in your browser. ## 05 Questions Questions about cookies: [info@nerix.ai](mailto:info@nerix.ai).
