You can only use this Service if you are a business and you have accepted these Terms. If you are not a business or acting on behalf of one, or if you do not agree to the Terms, please do not use the Service.

1.7.       Subject to the limitations of the chosen plan, Customer may authorize any person to be an organiser or a participant. The Customer, the Customer’s organisers and the Customer’s participants are, collectively, users of the Service (“Users”).

14.1.       The period of these Terms will commence on the date when Customer or Customer’s organiser accepts the Terms on our Website or Mobile App by signing up and creating an account (“Effective Date”).

14.2.       As our business evolves, we may change these Terms. All Customers shall be notified about any changes to the Terms through updating our website or we may message the Customers via the Service. If a Customer would like to receive notifications of material changes to the Terms via email, Customer may sign up by emailing with the subject “Subscribe to Terms Changes Notifications” specifying the email address they would like the notifications sent to.

Customer shall have a reasonable time specified in the notification to object to any material changes. If Customer or Customer's organiser uses the Services after the effective date of any changes, that use will constitute Customer’s acceptance of the revised Terms. If the Customer does not agree to the material changes, the Customer may terminate the relationship immediately by deleting their account. Such termination is without prejudice to any fees incurred by Customer prior to the termination.

Customer can review the most current version of the Terms at any time by visiting this page. Any material revisions to these Terms will become effective on the date set forth in our notice, and all other changes will become effective on the date we publish the change.

  3. in an event of bankruptcy or other cause preventing Slido from providing the Service.

14.6.       Either party may terminate the relationship without cause in writing with a one-month notice period (the notice period commences on the first calendar day of the month following the calendar month in which the notice of termination was delivered to the other party). If Slido terminates without cause, Slido shall reimburse the Customer for any unused Service pro rata.

14.7.       Customer may terminate the free Service immediately without cause by deleting their account.

15.2.       Notices under this section shall be effective upon delivery if not automatically rejected or refused by a server.

16. Entire agreement and severance

16.1.       The Terms and an invoice, where an invoice is issued, shall constitute the entire agreement between Slido and Customer with respect to the subject matter hereof and supersede all prior or contemporaneous oral and written agreements, proposals, negotiations, representations, commitments and other communications between Slido and the Customer, including but not limited to any fixed terms and conditions on any purchase orders or vendor registration forms. All prior negotiations between Slido and the Customer regarding the subject matter described herein have been merged into the Terms and there are no understandings, representations, or terms, oral or written, express or implied, regarding the subject matter described herein other than those set forth herein.

16.2.       If any provision of these Terms is or becomes prohibited by law or is judged by a court to be unlawful, void or unenforceable, the provision shall, to the extent required, be severed from these Terms and rendered ineffective as far as possible without modifying the remaining provisions of these Terms, and shall not in any way affect any other circumstances of or the validity or enforcement of the remainder of these Terms.

16. Entire agreement and severance

These Terms form the entire agreement between you and Slido and nothing else will count. If any clauses of these Terms are held by a court to be invalid, these should be severed and the rest of the Terms should go on.

17. Assignment

17.1.       Neither Slido nor the Customer may assign the Terms or any rights or obligations mentioned herein without the prior written consent of the other party, such consent not to be unreasonably withheld or delayed. However, either Slido or the Customer may assign these Terms without the consent of the other party provided such assignment fulfils the following criteria:

  1. it is to a parent, successor in interest or an Affiliate (meaning any entity with respect to which the party owns or controls, directly or indirectly, greater than fifty percent (>50%) of the outstanding voting securities, but only so long as the entity meets such requirements);
  2. the assigning party provides written notice of such assignment to the other party; and
  3. the party assuming obligations hereunder agrees to do so in writing and has adequate resources to meet its obligations hereunder.

18. Third party rights

18.1.       Except as expressly provided otherwise, Slido or the Customer do not intend any term of these Terms to be enforceable by any third parties. Slido and the Customer do not require the consent of any third party to terminate, rescind or to agree any variation, waiver or settlement in relation to it.

18. Third party rights

Third parties won’t have a say or benefit in anything concerning these Terms.

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.

19. No waiver

If either party messes something up, but the other party suffers it for a time, this won’t mean the first party can’t complain later.

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. Such circumstance might be an impediment that has occurred independently of the will of the obligated party and prevents it from fulfilling its obligation if it cannot reasonably be assumed that the obligated party would divert or overcome this impediment or its consequences and that it would anticipate that impediment at the time of the beginning of its commitment.

20. Force majeure

If something unforeseeable happens that’s beyond the reasonable control of either of us (e.g. war, riot, floods, hurricanes…) and either of us doesn’t do what we should under these Terms, we will be excused from that obligation.

21. Relationship between the Parties

21.1.       These Terms shall not constitute or imply any partnership, joint venture, agency, fiduciary or other relationship between Slido and the Customer other than the contractual relationship expressly provided for in these Terms.

21. Relationship between the Parties

You are just buying the Service from us and we’re just selling the Service to you. This doesn’t make us partners, joint venture, agent and principal, fiduciaries or anything else other than service provider and customer.

22. Survivability

22.1.       All sections of these Terms relating to User obligations, confidentiality, intellectual property, disclaimers, limitation of liability, dispute resolution, compliance with laws or those sections of these Terms that, by their nature and content, are intended to survive the completion, rescission, termination or expiration of these Terms shall so survive and continue to bind the parties for the period of time permitted under applicable law.

22. Survivability

When these Terms end, there are some responsibilities that won’t end.

23. Dispute resolution, jurisdiction and governing law

23.1.       Where there is a dispute the aggrieved party shall notify the other party in writing of the nature of the dispute with as much detail as possible about the deficient performance of the other party. The parties will attempt in good faith to resolve any dispute or claim arising out of or in relation to these Terms through negotiations between a director of each of the parties with authority to settle the relevant dispute.

23.2.       If the dispute cannot be settled amicably within 60 days from the date on which either party has served written notice on the other of the dispute then the remaining provisions of this clause 23 shall apply.

23.3.       The parties shall irrevocably submit to the exclusive jurisdiction of the Slovak courts for the purposes of hearing and determining any dispute arising out of these Terms, if the parties cannot resolve such dispute by the procedure set out above.

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. However, the parties agree that neither the Terms nor any instructions or communications from Slido have to be in the Slovak language and that the last two versions of the Terms shall be available via the Website at 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.

23. Dispute resolution, jurisdiction and governing law

If we don’t agree about something essential, we will first try to talk about it and resolve it in a friendly way. If talking won’t cut it, either of us can take it to the Slovak courts, applying Slovak law.

Who we are and where to contact us

You can find our identification and ways to contact us here. Our Data Protection Officer at would also be happy to help with your privacy questions, concerns and would also welcome your feedback.

In most cases we are the controller, meaning we decide what personal data to collect from you, how and why and are responsible for dealing with your requests to exercise your rights. Where our Customer (represented by the organiser of your event) is the controller, you can either contact them directly or if you cannot contact them directly, contact us and we can pass your query on to them.

Contract and/ or legitimate interests of cooperation to provide the best Service possible

Because of the nature of the Service we don’t expect any sensitive data or any other personal data in any other fields.

We may anonymise and aggregate data so it wouldn’t be personal data and use or share such data for any other legitimate business purpose. We may share non-personal aggregated data publicly (e.g. to show trends about the usage of our Services).

The personal data we collect could generally cover these categories under the California Consumer Privacy Act:

We might also use or share your personal data for other legal reasons and purposes if we have a good faith belief it is reasonably necessary e.g.

or with your consent.

Where we get your personal data from

Apart from technical data which we collect automatically, we get personal data from you as the data subject directly - it’s what you give us.

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

How long we keep your personal data

How long we keep your personal data depends on the type of data and the purpose for which we use the data. We will keep your personal data only for the period necessary to fulfil the purposes unless the law tells us to keep it for longer.

For Customer Data, this will generally be for the Term plus the period from the expiry of the Term until deletion of all Customer Data by Slido in accordance with its back up policies.

The Service also offers certain controls for the Users to automatically delete their data via the Service themselves.

Sharing and transfers

Who we share your data with depends on who you are:

Slido is based in Slovakia, EU, but some of our staff and service providers we rely on to provide the best Service to you work outside of Slovakia or the EU. This means your personal data may be transferred outside of the country where you live. Having said that, we will only transfer or share your personal data if there are sufficient controls in place to protect it (e.g., we may make the recipients promise they will protect your data in our contracts with them).

For specific information about which service providers we use, what for, what personal data we send them, where they will process that data and how we make sure it’s protected, please see our table of Processors (Service Providers).

For more information on sharing and transfers, please also see sections 3 and 4 of this Privacy Policy.

Your rights

Depending on where you are, the law gives you some rights around your personal data. We believe you should have control over your data no matter where you live, so where we are the controller, we decided to give you all these rights below regardless of where you are. If our Customer is the controller, you should contact them directly or let us know whether we should pass your query on to them.

  1. Right to information: Simply, we need to tell you how we use your personal data. We do this through this Privacy Policy and privacy notices when we collect your personal data and through answering any questions from you if anything is unclear.
  2. Right to access (right to know): If you ask us for this, we will send you what specific pieces of data we collect about you in a secure way. Both organisers and participants can see their profile data via the Service in their profiles.
  3. Right to rectification: If you ask us for this, we will correct any inaccurate, incomplete or out of date personal data. Both organisers and participants can change their profile data via the Service.
  4. Right to erasure (right to be forgotten): If you ask us for this, we will delete certain personal data, for example when it is no longer necessary for us to use the personal data for the purpose, or when you have withdrawn your consent. Organisers have an option in the Service to delete event content data only, or delete their account (which deletes all data under that account including from our systems). Unless the organiser doesn’t allow them to, participants can delete their profile through the Service while at an event.
  5. Right to restriction of processing: If you ask us for this, we will block or temporarily freeze your personal data use (usually while a dispute is resolved).
  6. Right to portability: If you ask us for this, we will send you your personal data in a way you can use or share somewhere else.
  7. Right to withdraw consent: Wherever it is optional to collect personal data about you, we transparently inform you about it and we ask for your consent. When you change your mind, there is always a convenient way to let us know.
  8. Right to object: If you ask us for this, we will opt you out or unsubscribe you from the relevant use. This usually applies to analytical and advertising cookies, Switcher diagnostics and marketing. You can control your cookies in Privacy Settings and can opt out of analysis and advertising. An organiser can unsubscribe from emails via the link at the bottom of the email or set their email preferences via the Service.
  9. Right to receive the Service on equal terms: We will never discriminate against you for exercising your rights.
  10. Right to complain to a supervisory authority: If you have any concerns about how we handle your privacy, it is a feedback we want to hear so we can improve. Please do let our Data Protection Officer know at You also have a right to complain to your national supervisory data protection authority, or the Slovak Data Protection Authority. See here for more information about how to complain to the Slovak Data Protection Authority.

The fastest way to submit and get a rights request resolved is via the automatic controls you have in the Service. However, if you can’t do that for whatever reason, you can always contact us (please see our contact details in the contacts section above) or if you are a California resident wanting to exercise your rights, you can call us at this toll free number: +1 855 659 0501.

Please note that for your protection and the protection of your data we won’t be able to resolve your request unless we successfully verify it is you. This will usually be via asking you to log in where applicable or via an email reasonably associated with you. You can also authorise an agent to make a request on your behalf, but you will need to provide us with sufficient written authorization or a power of attorney, signed by you, for the agent to act on your behalf and will still need to verify your identity directly with us. We collect as little data as possible, offer options for participants to be anonymous and automatic controls for users, so sufficient verification may not always be possible. If we can’t verify it is you, we can only respond with information contained in this Privacy Policy or can deny your request.

Some of the rights above are not absolute meaning we might not be able to comply with them immediately or fully, for example if the law makes us keep some personal data (e.g. we won’t be able to delete all your personal data if the law makes us keep records of your request and our compliance), or to maintain backups for the protection of your personal data (e.g. your information will be in our backups for 28 days before it is deleted automatically and permanently.)


To protect your personal data, we’ve put reasonable technical and organisational security measures in place. For more information, please see our Security Appendix.


As our business evolves, Slido may change this policy from time to time to keep up to date with the changes to our Service and our business, and laws applicable to us and you. We will, however, always maintain our commitment to respect your privacy. We will post any changes on this page. If you’d also like to be notified of material changes by email, you can sign up by emailing with the subject “Subscribe to Privacy Policy Notifications” and telling us the email address where we should send such notifications. If you continue to use the Services after those changes are in effect, you agree to the revised policy. If you disagree, you’ll have to stop using the Service and delete your data.


We do not knowingly collect personal data of children where the law would require us to obtain the consent of their parents. If you would like to collect personal data from children through the Service where parental consent is required by law, you agree to get all the consents to do this legally.

Other privacy policies

We may sometimes include or offer third party products or services on our Websites or through the Service. These third parties will have their own privacy policies and it is up to you to follow these. We’re not responsible for these third parties. However, we do our best to protect our Websites and Services and welcome any feedback about these third parties.
