RecSys 2021 Cancelations and Refund Policy

All refund requests must be made in writing by email to by September 1, 2021 at 11:59 PM Eastern Time. A processing fee of 20€ will be assessed for full-rate registrations. A processing fee of 10€ will be assessed for reduced rate registrations. In the case of an exchange request (from physical to virtual attendance or vice-versa) must be made in writing to by September 1, 2021 at 11:59 PM Eastern Time. A processing fee of 20€ will be assessed for full-rate registrations. A processing fee of 10€ will be assessed for reduced rate registrations. Requests for registration exchange from physical to virtual received after that will be processed but no refunds will be granted to the participants.
Regrettably, general cancellations received after that date cannot be honored. The conference committee recognizes that sometimes last-minute cancellations can't be avoided. However, the conference incurs expenses for which it is liable based on registration counts. Registrants who find themselves unable to attend should be aware that registrations are transferable, but in general the conference committee cannot assist in finding an appropriate recipient. If the COVID-19 travel rules & regulations prevent you from attending the physical conference, we ask you to request an exchange by writing as soon as possible. A processing fee of 10€ will be assessed for full-rate registrations. A processing fee of 5€ will be assessed for reduced rate registrations.

In the unlikely event that the physical part of the conference is cancelled due to circumstances beyond the organizers' control, all attendees will participate virtually. In this case, refunds will be calculated and processed in a best-effort approach, and the amount of the refunds will depend on the expenses and financial commitments incurred by the conference as of the cancellation date.

Economically Developing Countries

The RecSys 2021 is planned to take place in Amsterdam, The Netherlands. For full transparency, on top of the normal costs of hosting in physical space (food, space rental, etc), the costs of hosting in virtual space are not insignificant. These costs include building and maintaining an online platform for the conference, live streaming, hosting and software licensing fees, and hiring logistical and tech support staff to ensure the conference runs smoothly.
Additionally, we are continuing and growing our programs to support equity and inclusion at the conference: In regions and countries where it is safe and feasible, we will continue to offer childcare support during the conference in the form of a childcare subsidy. We also plan to offer "data grants'' for attendees with limited access to the internet.

In striving for a conference cost that is affordable for all, we also have deeply discounted rates available for those registering in countries designated by ACM as "economically developing." To receive the discount code for registration, please be sure to select your country during the CVENT registration process. If you have questions about price or eligibility, please email .

Please contact our Diversity Inclusion and Accessibility co-chairs (or visit our inclusion page) for more information on how RecSys can support your attendance–including fee waivers.
