circa, by Tilpop, Inc. Last updated: 4 November 2026.
The following Terms of Use (“Terms”) apply to the circa mobile application, the pages at tilpop.ai/circa, and the services made available through them (together, the “Service”), which are owned and operated by Tilpop, Inc. (“Tilpop,” “we,” “us,” or “our”). By creating an account, joining a gathering, or otherwise accessing or using the Service, whether via mobile device, computer, or other technology, you acknowledge that you have read and agree to be bound by these Terms and by our Privacy Policy, which is incorporated into these Terms by reference, in their entirety, as they may be amended from time to time. If you do not agree, do not use the Service.
We may amend these Terms at any time. An amendment is effective upon posting to the Service, except that a material amendment will be announced in the app or by email before it takes effect. Your continued use of the Service after an amendment is effective is your acceptance of it.
You must be at least 13 years old to hold an account. A person under 13 may be listed on a guest list as part of an adult’s party, but the account, and the responsibility for it, is the adult’s. You must provide a real name by which the other members of a gathering will know you. You are responsible for all activity under your account and for keeping your sign-in credentials confidential, and you may not allow any other person to access the Service using your account.
A “Gathering” is a private space within the Service created by a member (the “Host”). The Host determines who is on the guest list, who holds co-host or planner privileges, and what appears on the itinerary, and may remove any member from the Gathering at any time. A guest joins a Gathering only by an invitation the Host has issued and sees only the Gatherings to which they have been invited. Hosts are solely responsible for the persons they invite and the information they publish within a Gathering. Tilpop does not vet guest lists, is not a party to any Gathering or to the event it concerns, and has no responsibility for the conduct of any Host or guest. You may not share an invitation code with any person the Host has not invited.
You retain ownership of the photographs, videos, messages, posts, comments, playlist additions, travel details, and other material you submit to the Service (“Your Content”). By submitting Your Content you grant Tilpop and its Affiliates, successors, and assigns a non-exclusive, worldwide, royalty-free, fully paid-up, transferable, sublicensable (directly and indirectly through multiple tiers), perpetual, and irrevocable licence to host, store, copy, reproduce, resize, transmit, display, perform, distribute, modify, create derivative works of (such as thumbnails, previews, and a Gathering’s Memory), and otherwise use Your Content, in any form, medium, or technology now known or later developed, in order to operate, maintain, secure, improve, and develop the Service and to provide it to the members of the Gathering in which you submitted it. This licence continues for as long as Your Content remains in a Gathering, and survives your removal of it or the deletion of your account to the extent described in the Privacy Policy.
Tilpop does not sell Your Content or use it to display advertising. Tilpop does not use Your Content to train machine learning models except with your opt-in consent, and any such use would be described in the Privacy Policy first. Tilpop may use Your Content in its own promotion or marketing only with the express permission of the Host of the Gathering and of each identifiable person depicted.
You represent and warrant that you own or have all rights, licences, consents, releases, and permissions necessary to submit Your Content and to grant this licence, including the consent of each identifiable person depicted in Your Content to the use of their name and likeness in the manner contemplated by the Service and these Terms, and that Your Content does not and will not infringe the intellectual property, privacy, publicity, or other rights of any third party. You assume all risk associated with Your Content and have sole responsibility for its accuracy, legality, and appropriateness.
Other members of a Gathering may save a photograph you have shared to their own device or add an event you have posted to their own calendar; that is inherent in sharing within a Gathering. You may delete Your Content at any time. A Host may remove any content from their Gathering. Tilpop may preserve or disclose Your Content where required by law or where reasonably necessary to comply with legal process, enforce these Terms, respond to a claim that it violates the rights of others, or protect the rights, property, or safety of Tilpop, its members, or the public.
The Service is owned and operated by Tilpop, and (1) all software, designs, text, images, graphics, and other content and materials comprising the Service, other than Your Content and the content of other members (collectively, “Content”), and (2) the circa name, the circa. wordmark, the c. mark, and all other Tilpop trademarks, trade names, service marks, logos, and URLs (collectively, “Marks”) are the property of Tilpop or its licensors and are protected by copyright, trademark, and other laws. Subject to these Terms, Tilpop grants you a limited, personal, non-exclusive, non-transferable, revocable licence to install and use the app on a device you own or control, and to access the Content, solely for your participation in Gatherings of which you are a member. Except as expressly permitted in these Terms, you may not (i) adapt, copy, distribute, modify, reverse-engineer, decompile, or prepare any derivative work based on the Service or any Content, in whole or in part; (ii) sell, rent, lease, or sublicense the Service or any Content; (iii) use any Mark without our prior written permission; (iv) access the Service by any automated means or interfere with its operation or security; or (v) permit any third party to do any of the foregoing. Any suggestion or feedback you send us may be used by Tilpop without restriction or obligation to you.
You agree not to submit or transmit through the Service any material that is unlawful, defamatory, threatening, harassing, sexually explicit, or infringing, or that you do not have the right to share, including a photograph of a person who would not consent to its sharing; to impersonate any person or join a Gathering to which you were not invited; to use the Service to send unsolicited messages or to collect other members’ details for any purpose beyond the Gathering; or to use the Service in violation of any applicable law. Any member may report content or another member from within the app, Hosts may remove content and members from their Gatherings, and Tilpop will act on reports of objectionable content within 24 hours, including by removing the content and ejecting the member responsible.
The Service incorporates information and functionality from third parties, including weather, flight, mapping, destination, and music providers, and a language model that powers Ask circa. Such information is provided as received and may be inaccurate, incomplete, or out of date. Ask circa answers from the content of your own Gathering and can be wrong; the Host’s itinerary is authoritative as to any time or place. Apple Music features require your own Apple Music subscription and are subject to Apple’s terms.
You may delete your account from within the app at any time. Where you are the Host of a Gathering, the Gathering passes to a co-host you designate or, if it has none, closes for all of its members when your account is deleted, and the app tells you which before you confirm. Tilpop reserves the right, at its sole discretion, to suspend or terminate your ability to access or use the Service, and to block or prevent future access to and use of the Service, where you have breached these Terms, where your use harms other members or the Service, or where the law requires. Tilpop may, in its sole discretion, terminate, change, modify, suspend, make improvements to, or discontinue any or all aspects of the Service, temporarily or permanently, at any time. You agree that Tilpop shall not be liable to you or to any third party for any such modification, suspension, or discontinuance, and you should keep your own copies of any photographs that matter to you.
TILPOP MAKES NO REPRESENTATION OR WARRANTY IN CONNECTION WITH THE SERVICE OR ANY CONTENT, ALL OF WHICH WE PROVIDE ON AN “AS IS” AND “AS AVAILABLE” BASIS. TILPOP HEREBY DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING, WITHOUT LIMITATION, WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT, WITH RESPECT TO THE SERVICE AND CONTENT. TILPOP DOES NOT WARRANT THAT THE OPERATION OF THE SERVICE WILL BE UNINTERRUPTED OR ERROR-FREE, THAT DEFECTS WILL BE CORRECTED, THAT TRANSMISSIONS OR DATA WILL BE SECURE OR WILL NOT BE LOST, THAT INFORMATION OBTAINED FROM THIRD-PARTY SERVICES OR FROM ASK CIRCA WILL BE ACCURATE, OR THAT THE SERVICE OR THE SERVERS THAT MAKE IT AVAILABLE ARE FREE OF VIRUSES OR OTHER HARMFUL COMPONENTS. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF IMPLIED WARRANTIES, SO SOME OF THE FOREGOING MAY NOT APPLY TO YOU.
TO THE FULLEST EXTENT PERMITTED BY LAW, NEITHER TILPOP, NOR ANY PARENT OR SUBSIDIARY OF TILPOP, NOR ANY STOCKHOLDER, DIRECTOR, OFFICER, EMPLOYEE, AGENT, CONSULTANT, CONTRACTOR, LICENSOR, REPRESENTATIVE, OR ADVISER OF TILPOP OR OF ANY PARENT OR SUBSIDIARY (EACH, AN “AFFILIATE”) SHALL BE LIABLE FOR ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL, EXEMPLARY, PUNITIVE, OR INDIRECT DAMAGES, OR FOR ANY LOSS OF DATA, PHOTOGRAPHS, GOODWILL, REVENUE, OR OPPORTUNITY, OR OTHER DAMAGE, EXPENSE, OR LOSS, REGARDLESS OF THEORY OF LIABILITY, WHETHER ARISING UNDER CONTRACT, TORT (INCLUDING NEGLIGENCE), STATUTE, EQUITY, OR OTHERWISE, ARISING IN CONNECTION WITH (1) THE SERVICE OR ANY CONTENT; (2) YOUR USE OF OR INABILITY TO ACCESS THE SERVICE, INCLUDING A MISSED EVENT, A WRONG TIME OR PLACE, OR A LOST PHOTOGRAPH; OR (3) THE CONDUCT OR CONTENT OF ANY HOST, GUEST, OR OTHER MEMBER, EVEN IF TILPOP HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. THE TOTAL LIABILITY OF TILPOP AND ITS AFFILIATES FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS SHALL NOT IN ANY EVENT EXCEED THE GREATER OF THE AMOUNT YOU PAID TILPOP FOR THE SERVICE IN THE TWELVE MONTHS PRECEDING THE CLAIM AND ONE HUNDRED U.S. DOLLARS (US$100). NOTHING IN THESE TERMS LIMITS OR EXCLUDES LIABILITY FOR FRAUD, FOR DEATH OR PERSONAL INJURY CAUSED BY NEGLIGENCE, OR FOR ANY LIABILITY THAT CANNOT BE LIMITED OR EXCLUDED BY LAW.
SOME JURISDICTIONS DO NOT ALLOW THE DISCLAIMER OR EXCLUSION OF CERTAIN WARRANTIES OR THE LIMITATION OR EXCLUSION OF LIABILITY FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO SOME OF THE ABOVE MAY NOT APPLY TO YOU. IF YOU ARE DISSATISFIED WITH ANY PORTION OF THE SERVICE OR WITH THESE TERMS, YOUR SOLE AND EXCLUSIVE REMEDY IS TO DISCONTINUE USE OF THE SERVICE. IF YOU ARE A RESIDENT OF NEW JERSEY, THE SECTIONS TITLED “DISCLAIMER,” “LIMITATION OF LIABILITY,” AND “INDEMNITY” ARE INTENDED TO BE ONLY AS BROAD AS IS PERMITTED UNDER THE LAWS OF THE STATE OF NEW JERSEY, AND IF ANY PORTION OF THEM IS HELD INVALID UNDER THOSE LAWS THE REMAINDER CONTINUES IN EFFECT.
To the extent permitted by applicable law, you agree to defend, indemnify, and hold harmless Tilpop and its Affiliates from and against any and all claims, losses, damages, liabilities, and expenses, including reasonable attorneys’ fees, arising out of or relating to your use of the Service (including any Gathering or event planned through it), Your Content, your breach of these Terms, or your violation of any law or of the rights of any person. Tilpop may assume the exclusive defence and control of any matter subject to indemnification, in which case you agree to cooperate with Tilpop’s defence, and you may not settle any such claim without Tilpop’s written consent.
These Terms are governed by the laws of the State of Delaware, United States, without regard to its conflict of laws principles, and by the Federal Arbitration Act with respect to the section below.
PLEASE READ THIS SECTION CAREFULLY. IT REQUIRES (WITH LIMITED EXCEPTIONS) THAT DISPUTES BETWEEN YOU AND TILPOP BE RESOLVED BY BINDING INDIVIDUAL ARBITRATION, AND IT WAIVES YOUR RIGHT TO A JURY TRIAL AND TO PARTICIPATE IN A CLASS ACTION.
This section is the “Arbitration Agreement.” You and Tilpop agree that any dispute, claim, or controversy that has arisen or may arise between you and Tilpop, whether arising out of or relating to these Terms (including their breach, termination, enforcement, interpretation, or validity), the Service, or any aspect of the relationship between us (a “Dispute”), will be resolved exclusively by final and binding arbitration rather than in court, except that (a) either party may assert an individual claim in small claims court if the claim qualifies, and (b) either party may seek injunctive or other equitable relief in court to protect its intellectual property rights. This Arbitration Agreement does not prevent you from bringing issues to the attention of a federal, state, or local agency, which may, if the law allows, seek relief against Tilpop on your behalf. By entering into these Terms, you and Tilpop each waive the right to a trial by jury and to participate in a class action.
YOU AND TILPOP AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY ON AN INDIVIDUAL BASIS AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, CONSOLIDATED, OR REPRESENTATIVE ACTION OR PROCEEDING. UNLESS BOTH YOU AND TILPOP AGREE OTHERWISE, THE ARBITRATOR MAY NOT CONSOLIDATE OR JOIN MORE THAN ONE PERSON’S CLAIMS AND MAY NOT PRESIDE OVER ANY FORM OF CONSOLIDATED, REPRESENTATIVE, OR CLASS PROCEEDING. THE ARBITRATOR MAY AWARD RELIEF ONLY IN FAVOUR OF THE INDIVIDUAL PARTY SEEKING RELIEF AND ONLY TO THE EXTENT NECESSARY TO PROVIDE RELIEF WARRANTED BY THAT PARTY’S INDIVIDUAL CLAIMS, EXCEPT THAT YOU MAY PURSUE, AND THE ARBITRATOR MAY AWARD, PUBLIC INJUNCTIVE RELIEF WHERE APPLICABLE LAW REQUIRES IT FOR THIS PROVISION TO BE ENFORCEABLE.
Most concerns can be resolved quickly by writing to support@tilpop.ai. Before starting an arbitration, the party raising a Dispute must send the other a written Notice of Dispute (the “Notice”) describing the nature and basis of the Dispute and the specific relief sought. Notice to Tilpop is sent to support@tilpop.ai with the subject line “Notice of Dispute”; Notice to you is sent to the email address on your account. If the Dispute is not resolved within sixty (60) days after the Notice is received, either party may commence arbitration. The amount of any settlement offer will not be disclosed to the arbitrator until after the arbitrator has determined the amount, if any, to which a party is entitled.
The arbitration will be administered by the American Arbitration Association (“AAA”) under its Consumer Arbitration Rules (the “AAA Rules”), available at adr.org, as modified by this Arbitration Agreement, before a single neutral arbitrator. The arbitrator, and not any court or agency, has exclusive authority to resolve any Dispute relating to the interpretation, applicability, enforceability, or formation of this Arbitration Agreement, including any claim that all or part of it is void or voidable. The arbitrator must follow these Terms as a court would and may award, on an individual basis, the same damages and relief a court could award. Any hearing will take place in the county where you reside or by video conference; for a claim of US$10,000 or less you may choose to proceed on the documents alone, by telephone, or in person. The arbitrator will issue a reasoned written decision, and judgment on the award may be entered in any court of competent jurisdiction.
Filing, administration, and arbitrator fees are allocated as provided in the AAA Rules. If you demonstrate to the arbitrator that the cost of arbitration would be prohibitive compared with the cost of litigation, Tilpop will pay as much of those fees as the arbitrator deems necessary to prevent the arbitration from being cost-prohibitive. This does not require Tilpop to pay any part of your attorneys’ fees or costs, which are governed by the AAA Rules and applicable law.
If Tilpop changes this Arbitration Agreement while you are a user of the Service, you may reject the change by written notice to support@tilpop.ai within thirty (30) days of the change taking effect, stating your full name and the email address on your account. By rejecting a change you agree to arbitrate any Dispute under the version of this Arbitration Agreement you last accepted.
All aspects of the arbitration, including any award, are confidential except as needed to enforce it. If any part of this Arbitration Agreement other than the class action waiver is held unenforceable, it will be replaced by an enforceable term that comes closest to the parties’ intention, and the remainder will be enforced. If the class action waiver is held unenforceable as to a particular Dispute, this Arbitration Agreement is void as to that Dispute, which shall then proceed in court under the paragraph below. This Arbitration Agreement survives termination of these Terms and of your account.
Any Dispute not subject to arbitration shall be brought exclusively in the state or federal courts located in the State of Delaware, and you and Tilpop each consent to the personal jurisdiction of those courts. If you reside in the European Union, the United Kingdom, or another jurisdiction whose law entitles you to bring a claim in the courts of your home country or prohibits mandatory arbitration of consumer disputes, this Arbitration Agreement does not apply to you and nothing in this section limits that right or any other right that cannot be waived by agreement.
The app is distributed through Apple’s App Store and Google Play. These Terms are between you and Tilpop only; Apple is not a party to them, has no obligation to furnish maintenance or support for the app, and is not responsible for any claim relating to the app or your possession or use of it, including product liability, legal or regulatory compliance, and intellectual property claims. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.
For the app installed from Google Play, Google is not a party to these Terms and has no obligation to furnish maintenance or support for the app.
These Terms and the Privacy Policy are the entire agreement between you and Tilpop concerning the Service and supersede any prior agreement between us about it. If any provision is held invalid, the remainder continues in effect and the court or arbitrator should give effect to the parties’ intention as reflected in the invalid provision. Tilpop’s failure to enforce any provision is not a waiver of it. To the extent permitted by law, any claim arising out of or relating to the Service or these Terms must be filed within one (1) year after it arose or is forever barred. You may not assign these Terms without Tilpop’s written consent; Tilpop may assign them without restriction, including in connection with a merger, acquisition, or sale of assets. Notices to you may be given by email to the address on your account or through the Service. Section titles are for convenience only, and “including” means “including without limitation.” Tilpop is not in default for any failure or delay caused by circumstances beyond its reasonable control, including outages of networks, power, or third-party services, natural disaster, epidemic, or civil disturbance.
