This Recommender Systems and Advertising Transparency Notice (hereinafter referred to as the Notice) describes how the ReloSale platform (hereinafter referred to as the Platform, ReloSale) uses algorithmic, statistical, product and editorial mechanisms to generate recommendations, sort, prioritize, select, rank and otherwise order content displayed to users, including listings, search results, collections, "similar listings" blocks, personalized selections, advertising placements, commercial integrations and other interface elements.
The Notice also discloses the Platform's advertising transparency principles: how paid services, commercial placements and advertising integrations may affect content visibility, and how ReloSale informs users about the commercial nature of such placements.
This Notice applies to all users and visitors of the Platform, including private individuals, professional sellers, landlords, buyers, tenants, business account holders, advertisers, agents, agencies and other persons using ReloSale functionality or viewing Platform materials.
The Notice applies in conjunction with the Terms of Use, Privacy Policy, Cookie Notice, Listing Rules, Paid Services Terms and other applicable ReloSale documents.
For the purposes of this Notice, recommender systems refer to any algorithmic, statistical, product and/or editorial mechanisms that influence which content a user sees first, in what order and at what positions listings, collections and other materials are displayed, as well as which interface elements are offered to the user during use of the Platform.
In particular, recommender systems include:
When generating recommendations, rankings and content display, the Platform may take into account the following signals (factors), both individually and in combination:
The specific set and weight of each signal are determined by the Platform at its own discretion and may vary depending on category, country, query type, user type, interface used and other circumstances.
The Platform may use data about a specific user's interactions (views, search queries, saves, responses, hides, behavioural history, preferences and other signals) to increase the relevance of displayed content -- that is, to personalize recommendations.
Personalization is aimed at offering the user listings and selections that are more likely to match their interests, needs and context of Platform use.
The Platform may provide users with settings to manage personalization, including the ability to disable personalized recommendations, manage cookies and advertising preferences. The availability and scope of such settings depend on the product, country and current implementation.
Personalization does not guarantee the best result in every individual case. The Platform strives to improve relevance but does not guarantee that personalized results will fully meet user expectations.
Even in the absence of personalization or when personalized recommendations are disabled, content display on the Platform is determined by a number of non-personalized factors, including:
Thus, even without personalization, the order and composition of displayed content are not random, but are determined by the Platform's algorithmic and product logic.
The Platform provides users with paid services that may affect the visibility, position, highlighting and display priority of listings. Such services may include:
Where applicable law requires labelling of commercial or advertising placements, the Platform marks such content with appropriate labels: "advertising", "promoted", "sponsored" or other similar designations.
Use of paid promotion services does not exempt a listing from compliance with Platform rules and does not allow bypassing moderation. The Platform reserves the right to reject, restrict or suspend promotion of a listing that violates the rules, regardless of its paid status.
The Platform may reduce visibility, limit impressions or exclude from recommendations listings and accounts that:
Visibility limitation may be applied automatically (algorithmically) and/or as a result of moderation actions, alongside other measures provided for by Platform rules (warning, rejection, suspension, removal, account blocking, etc.).
ReloSale is not obligated to and does not publicly disclose the following information related to the Platform's recommender and moderation systems:
This limitation is aimed at protecting the integrity, security and fairness of Platform operations and does not constitute a violation of users' rights to information.
The Platform may display its own advertising, partner advertising, promoted listings and other commercial placements in various interface elements, including search results, category pages, listing cards, the home page, recommendation blocks, push notifications, email newsletters and other channels.
Commercial placements may differ from organic content by position priority, placement in special blocks, visual design, labelling and/or other characteristics.
Where applicable law requires informing users about the commercial nature of a placement, the Platform marks such materials with appropriate labels or ensures visual differentiation between commercial and organic content.
The user understands that some content displayed on the Platform may have a commercial basis and that the presence of a commercial placement does not constitute endorsement, recommendation or guarantee by ReloSale with respect to the advertised product, service, object or advertiser.
To assess the effectiveness of recommender systems, advertising placements and Platform functionality, ReloSale may measure and analyze the following metrics:
Data collection and processing for effectiveness measurement are carried out in accordance with the Privacy Policy, Cookie Notice and applicable user consent settings.
Depending on the product, country and current implementation, the user may have the ability to:
The availability and scope of available settings are determined by the current implementation of the Platform and may vary depending on the product, country, account type and other circumstances. ReloSale strives to expand users' capabilities for managing recommendations and advertising preferences.
ReloSale reserves the right to modify, supplement or update this Notice at any time at its own discretion, including in connection with changes in legislation, introduction of new features, changes to algorithms, expansion of paid services, changes to product logic or for other reasons.
The current version of the Notice is published on the Platform at the corresponding address. The date of last update is indicated at the beginning of the document.
By continuing to use the Platform after changes are made to the Notice, the user confirms their acceptance of the updated version. If the user does not agree with the changes, they have the right to discontinue use of the Platform.
