This Cookie Policy explains how SellerDen AI (operated by E-com Solutions OÜ) uses cookies and similar technologies on https://sellerden.ai and the SellerDen AI application ("Service").
This Policy applies to users in the European Economic Area (EEA). For more information on how we process personal data, please see our EU Privacy Policy.
Cookies are small text files placed on your device when you visit a website. They allow the website to remember your actions and preferences over a period of time, so you don't have to re-enter them whenever you come back.
We also use similar technologies such as localStorage — a browser storage mechanism that works like cookies but is stored locally on your device.
We use four categories of cookies. You can manage your preferences for all non-essential categories through our cookie banner at any time.
These cookies are required for the Service to function. They cannot be disabled. No consent is required for these cookies under Article 5(3) of the ePrivacy Directive.

Marketing cookies are used to display relevant advertisements and track campaign performance. We place marketing cookies only with your consent.
Currently, we do not operate third-party advertising campaigns that place cookies. This section will be updated if marketing cookies are introduced.
In addition to cookies, we use browser localStorage as described in Section 2.2 above (Yandex Metrica). localStorage data is stored locally in your browser and is not transmitted with every HTTP request like cookies. You can clear localStorage data through your browser settings.
When you first visit sellerden.ai, you will see a cookie consent banner. You can:
You can change your preferences at any time by clicking the "Cookie settings" link in the footer of the website.
Withdrawing consent does not affect the lawfulness of processing based on consent before its withdrawal. To withdraw consent, use the cookie settings link in the footer, or clear your browser cookies and reset your preferences on your next visit.
You can also control cookies through your browser settings. Note that blocking all cookies may prevent parts of the Service from working correctly.
Some cookies set by third-party providers result in personal data being transferred outside the EEA:
