    • the assigning party provides written notice of such assignment to the other party; and
    • the party assuming obligations hereunder agrees to do so in writing and has adequate resources to meet its obligations hereunder.
  • 17.2. Any attempted assignment not in accordance with this clause shall be null and void.

19. No waiver

  • 19.1. Unless Slido or the Customer expressly waives its rights in writing no delay, neglect or forbearance on the part of either party in enforcing against the other party any term or condition of these Terms shall either be or be deemed to be a waiver or in any way prejudice any right of that party under these Terms. No right, power or remedy conferred upon or reserved for either party is exclusive of any other right, power or remedy available to that party.

20. Force majeure

  • 20.1. Neither Slido nor the Customer shall have any liability under or be deemed to be in breach of these Terms for any delays or failures in performance of these Terms which result from circumstances beyond the reasonable control of that party.

  • 23.4. These Terms and all matters arising from it and any dispute resolutions referred to above shall be governed by and construed in accordance with Slovak law notwithstanding the conflict of law provisions and other mandatory legal provisions.

If the Customer requires an earlier version of the Terms, Slido shall make these available to the Customer upon written request.
  • 23.5. Clauses 23.1. and 23.2. do not affect either party’s right to seek urgent interlocutory and/or injunctive relief.

Privacy Policy

This Privacy Policy is effective as of October 18th, 2018.

You can find the previous Privacy Policy here

sli.do s.r.o. (“Slido”) provides the Privacy Policy to inform users about policies and processes regarding the collection, use and disclosure of personally identifiable information (“personal information”) received from Slido users via www.sli.do, other domains run by Slido or third party integrations (“Sites”).

First things first

Simply said, we do not sell, trade or otherwise transfer your personal information to third parties in any manner that could be harmful, dangerous or violating your privacy. We are here to provide you with the interaction platform and if we are making you uncomfortable about your privacy, it is a feedback we want to hear from you. Please don’t hesitate to reach out to us at security@slido.com.

Information we collect

We collect and process information from you when you create an event, interact with an event or register on our Sites. You may be asked to enter details about you, but you always have an option to change your mind when you wish to anonymize yourself or even completely delete information about you from our service.

We collect information in the following ways:

  • Information you give us. For example, if you are an event organizer, our services require you to sign up for a Slido account. When you do, we’ll ask for personal information, like your name or email address. Or consider this, if you are an event participant, you may want to ask a question with your name - those are the moments when submitting your name is essential to provide you with required functionality, that’s why we ask for that.
  • Information we get from your use of our services. We collect information about the services that you use and how you use them, like when you enter an event or view and interact with our ads and content.

    This information includes:

    • Device Information. We collect device-specific information, such as your hardware model, operating system version, unique device identifiers. Slido may associate your device identifiers with your Slido account.
    • Log Information. When you use our services or view the content provided by Slido, we automatically collect and store certain information in server logs. This includes:
      • details of how you used our service, such as your search queries.
      • details about your connection, such as IP address, date, time, edge-location, ssl-protocol, ssl-cipher or time-taken to serve you requested site.
      • device event information such as crashes, system activity, hardware settings, browser type, browser language, the date and time of your request and referral URL.
      • cookies that may uniquely identify your browser or your Slido account.
    • Location Information. When you use the Slido Services, we may collect and process information about your actual location. Currently, we only use IP address as the source information to approximately determine your current location.
    • Unique Application Numbers. Certain Slido products (e.g. Slido Switcher) may include a unique application number. This number and information about your installation (for example, the operating system type and application version number) may be sent to Slido when you install or uninstall that service or when that service periodically contacts our servers, such as for automatic updates.
    • Local Storage. We may collect and store information (including personal information) locally on your device using mechanisms such as browser web storage (including HTML 5) and application data caches.
    • Cookies and similar technologies. We and our partners use various technologies to collect and store information when you use the Slido services, and this may include using cookies or similar technologies to identify your browser or device. We also use these technologies to collect and store information when you interact with services offered by our partners and third parties, such as advertising services or user behaviour analytics services. We may offer you services provided by our partners as a part of our Sites, in such case information about you is collected via a third party cookie.

Information we obtain about you from our partners may be associated with your Slido account. When such information is associated with your Slido account, we treat it as personal information.

For more information about how you can access, manage or delete information that is associated with your Slido account, visit the “Transparency and choice” section of this Privacy Policy.

Why do we need your information and how we use it

We use the information we collect from all of our services to provide, maintain, protect and improve them, to develop new ones, and to protect our Sites and our users. We also use this information to offer you tailored content – like proper instructions how to get the most out of Slido Services.

We will ask for your consent before using information for a purpose other than those that are set out in this Privacy Policy.

Slido processes personal information on servers of our infrastructure provider in Ireland and we use help of a few other specialized third party service providers as well. Therefore, we may process your personal information on a server located outside the country where you live.

Transparency and choice

People have different privacy concerns. Our goal is to be clear about what information we collect, so that you can make meaningful choices about how it is used. For example:

  • Wherever it is optional to collect additional information about you, we transparently inform you about what information we need, why we ask for it and we require your consent to process such information. When you change your mind, there is always a convenient way how to let us know.
  • You can always set your own Cookie preferences and therefore decide whether you agree to be on our radar when it comes to ads or behaviour analytics or not.
  • If you have a Slido account you can change information about you or completely permanently delete your account if you wish to be “forgotten”.
  • If you don’t have a Slido account, but you were interacting with any event via Slido, you can anonymize your activity and wipeout any personal information related with such interaction.
  • If you use Slido Switcher you are very welcome to decide whether we can use diagnostics data from your installation to make Switcher even better.

Accessing and updating your personal information

Whenever you use our services, we aim to provide you with access to your personal information. If that information is wrong, we strive to give you ways to update it quickly or to delete it – unless we have to keep that information for legitimate business or legal purposes.

We aim to maintain our services in a manner that protects information from accidental or malicious destruction. Because of this, after you delete information from our services, we may not immediately delete residual copies from our active servers and may not remove information from our backup systems - such information is completely removed according to our backup retention policy after 28 days.

Information we share

We do not share personal information with companies, organizations and individuals outside of Slido unless one of the following circumstances applies:

  • With your consent. We will share personal information with companies, organizations or individuals outside of Slido when we have your consent to do so. We require opt-in consent for the sharing of any sensitive personal information.
  • For external processing. We provide personal information to our affiliates or other trusted businesses or persons to process it for us, based on our instructions and in compliance with our Privacy Policy and any other appropriate confidentiality and security measures.
  • For legal reasons. We will share personal information with companies, organizations or individuals outside of Slido if we have a good-faith belief that access, use, preservation or disclosure of the information is reasonably necessary to:
    • meet any applicable law, regulation, legal process or enforceable governmental request;
    • enforce applicable Terms of Service, including investigation of potential violations;
    • detect, prevent, or otherwise address fraud, security or technical issues;
    • protect against harm to the rights, property or safety of Slido, our users or the public as required or permitted by law.

We may share non-personally identifiable information publicly and with our partners – like publishers, advertisers or connected sites. For example, we may share information publicly to show trends about the general use of our services.

If Slido is involved in a merger, acquisition or asset sale, we will continue to ensure the confidentiality of any personal information and give affected users notice before personal information is transferred or becomes subject to a different privacy policy.

Information security

We work hard to protect Slido and our users from unauthorized access to or unauthorized alteration, disclosure or destruction of information we hold. In particular:

  • We encrypt our services using SSL, in transit and at rest as well.
  • We offer you advanced SSO features when you access our services for both organizers and attendees, such as, Google SSO or SAML based SSO.
  • We review our information collection, storage and processing practices, including physical security measures, to guard against unauthorized access to systems.
  • We restrict access to personal information to those of Slido staff, and third parties who need to know that information in order to process it for us, and who are subject to strict contractual confidentiality obligations and may be disciplined or terminated if they fail to meet these obligations.

For more information about security at Slido, we highly recommend checking out our Security Standards which we strictly follow.

Compliance and cooperation with regulatory authorities

We regularly review our compliance with our Privacy Policy. If you feel like we’re falling short, please send us a complaint in writing. We value your feedback so we may contact you to ask for more information or to follow up. We work with the appropriate regulatory authorities, including local data protection authorities, to resolve any complaints regarding the transfer of personal data that we cannot resolve with our users directly.

In case you are curious how we have approached the EU General Data Protection Regulation, please see GDPR Commitment section of this page.


Slido may change this policy from time to time, and if we do we will post any changes on this page. If you continue to use the services after those changes are in effect, you agree to the revised policy.


Slido is committed to protecting the privacy of young children, and therefore does not knowingly collect or maintain personal information on the Sites or the service from persons under 16 years of age, except in compliance with children's online privacy protection law. Accordingly, children under the age of 16 may only use the service with the permission and supervision of their parents. Additionally, teachers and schools seeking to use the service in the classroom with children under 16 years of age are required to obtain express consent of such children's parents in compliance with the applicable law, prior to permitting such children to access or use the service.

Other privacy policies

At our discretion, we may occasionally include or offer third party products or services on our Sites. As these have separate and independent privacy policies, we have no responsibility and liability for the content and activities of these linked sites. However, we do our best to protect the integrity of our Sites and welcome any feedback about these sites and services.

Your consent

By using our site, you consent to our Site Privacy Policy and the way how and for what purpose we process your personal information.

Slido GDPR Commitment

Last updated February 27th, 2019.

Our Commitment

We’re committed to partnering with all Users enjoying Slido to help them understand and prepare for the General Data Protection Regulation (“GDPR”). The GDPR is the most comprehensive EU data privacy law in decades, which came into effect on May 25, 2018.

As well as strengthening and unifying user data privacy across the EU, it also puts new or additional obligations upon anyone that handles EU citizens’ personal data, regardless of where they are located.

On this page, we’ll explain our approach to achieving GDPR-compliance, both for ourselves and for our Customers.

Slido Way and Adoption

The GDPR’s updated requirements are significant and our team is working hard to bring Slido’s Service offerings and contractual commitments in line so Customers can prepare themselves before May 25, 2018. Measures to achieve this include:

  • Changes in our product itself. We are changing our user interfaces and service offerings in order to give all users (both event organizers and participants) more visibility, transparency and control over the data they submit to / via Slido.
  • Investments under the hood. We are working on improvements to our infrastructure, to fulfil all the requirements and obligations connected to continuous security monitoring, data breaches and security incident management.
  • Legal matters. Any Customer who accepts Slido Terms of Service also automatically accepts the Slido Data Processing Addendum, which is incorporated in the Terms. View Data Processing Addendum (“DPA”)
  • Policies. We have already updated our Privacy Policy and Security Standards. This is not the end of the story, we are working on our internal policies and practices to ensure that we are aligned with the GDPR requirements.

We’ll also continue to monitor the guidance around GDPR compliance from privacy-related regulatory bodies, and will adjust our plans accordingly if it changes.

Stay Updated

Fulfilling our privacy and data security commitments is important to us. So we’re happy to help you prepare for all the changes the GDPR brings. This page will be revised to reflect GDPR-related information as it becomes available. If you have any questions about how Slido can help you with compliance, we hope you’ll reach out to us at legal@slido.com.
