Cookie Policy

Last updated: 16 October 2026

Cookies are small text files a website saves in your browser. This page lists every cookie DotMax uses, and the other things we save in your browser, with what each is for and how long it lasts.

In short: we only use cookies that make the Service work or remember choices you made. We use no analytics, advertising or tracking cookies, and we do not add any other company’s cookies to our website or app. That is why we do not show a cookie banner. If that ever changes, we will ask for your consent first.

1. Cookies we use

Essential cookies sign you in, keep you secure and keep your order. The Service cannot work without them. Preference cookies remember a choice you made, such as a collapsed menu, and are set only when you make that choice.

All our cookies are first-party: they are set by and sent only to the site you are using. Sign-in cookies cannot be read by scripts on the page and are only sent over encrypted connections.

2. Other things saved in your browser

Some features save small items in your browser’s storage instead of a cookie. They stay on your device and are not sent to us with every request. Where a name ends in …, the rest is the id of a restaurant, order, QR code or user.

NameWherePurpose
ros.cart.…Local storageYour basket on a QR menu, so it survives a refresh.
ros:last-orderLocal storageYour last order number on a QR menu, so you can get back to it.
tf-feedback-done:…Local storageThat you already answered or closed the feedback question for an order.
ros:qr-open:…Session storageCounts a QR code scan once per visit, not on every refresh.
ros:agent-menu:…Session storageThe menu assistant’s conversation during this visit.
ros:guest-agent-mutedLocal storageWhether you muted the menu assistant’s voice.
ros:guest-agent-mic:…Local storageWhether you turned on the menu assistant’s microphone.
ros:guest-agent-voice-readyLocal storageThat this browser has already prepared the assistant’s voice (restaurant settings).
ros:guest-agent-just-taughtSession storageThat a DotMax team member just taught the assistant an answer in this tab, so its voice is recorded next.
ros:nav-recent:…Local storageDashboard pages you opened recently, for quick links.
bizdash.restaurants.savedFiltersLocal storageFilters a DotMax team member saved in the Business Dashboard.
tfd-themeLocal storageLight or dark look you chose on the website and live demo.
kokoro-voicesCache storageVoice files for the assistant, downloaded once from our server so they need not be fetched again.
Offline pagesCache storageThe “you’re offline” page and public pages you visited, so the app can open without a connection.

Session storage is cleared when you close the tab. Local storage and cache storage stay until you clear your browser’s site data.

3. Other companies

Our website and app load their fonts, scripts, images and videos from our own server. The one exception is a picture a restaurant chose to link from another website instead of uploading it, such as a dish photo: your browser then fetches that picture from the website that hosts it. Some links take you elsewhere only when you tap them, such as WhatsApp and Google Maps, and those services use their own cookies under their own policies.

If you use the menu assistant’s microphone, your browser’s own speech recognition may be provided by the browser’s maker (for example Google, in Chrome). See our Privacy Policy.

4. Your choices

  • You can see and delete cookies and site data in your browser’s settings, usually under Privacy or Site settings.
  • Blocking essential cookies will stop sign-in and ordering from working.
  • Clearing site data signs you out, empties a QR basket and resets your preferences.

5. Changes

We update this page and its date whenever we add, change or remove a cookie.
