1. What cookies are
Cookiesare small text files that a website saves in your browser. Similar technologies, such as your browser's local storage, work in the same way. They let a website remember things like your log-in session or your choices, so you do not have to repeat them on every visit.
This policy covers https://harmonia-b2b.com and the customer console at https://app.harmonia-b2b.ru (together, the "Site"), operated by Adekom PromMash LLP.
2. Types of cookies we use

|---|---|
| Essential | Needed for the Site to work: log-in sessions in the customer console, security, and remembering that you have seen the cookie notice. The Site cannot work properly without them. |
| Preferences | Remember your settings, such as interface choices, so the Site works the way you set it up. |
| Analytics | Help us understand how visitors use the website (which pages are visited, how long people stay, where visits come from) so we can improve it. |
