IMPORTANT — READ CAREFULLY. This Agreement contains a BINDING ARBITRATION clause, a CLASS ACTION WAIVER, and a JURY TRIAL WAIVER (Section 17) that affect your legal rights. It also limits our liability and disclaims warranties (Sections 14–15). By using the App you accept these terms.
By downloading, installing, accessing, or using Radius (the "App"), or by clicking "I Agree" where presented, you agree to be bound by this End User License Agreement (the "Agreement") between you and Radius ("we," "us," or "our"). If you do not agree to every provision of this Agreement, do not download, install, or use the App, and uninstall it from your device.
You must be at least 18 years old to use the App. By using Radius, you represent and warrant that (a) you are 18 or older, (b) you have the legal capacity to enter into this Agreement, (c) you are not barred from using the App under the laws of any jurisdiction that applies to you, and (d) you are not located in, under the control of, or a national or resident of any country subject to a U.S. Government embargo, nor listed on any U.S. Government list of prohibited or restricted parties. The App is not directed to children under 18 and we do not knowingly collect personal information from minors. If you believe a minor is using the App, contact contact@talkradius.com and we will investigate and terminate the account.
Subject to your ongoing compliance with this Agreement, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to download, install, and use the App on any Apple-branded device that you own or control, solely for your personal, non-commercial use, and subject to the Usage Rules set forth in the Apple Media Services Terms and Conditions. All rights not expressly granted are reserved. You agree not to, and not to permit any third party to: (a) copy, modify, adapt, translate, or create derivative works of the App; (b) reverse engineer, decompile, disassemble, or attempt to discover the source code or underlying algorithms of the App, except to the extent such restriction is prohibited by applicable law; (c) rent, lease, lend, sell, sublicense, distribute, or transfer the App to any third party; (d) remove, alter, or obscure any proprietary notices in the App; (e) use the App to build a competing product or service; or (f) use the App in any manner that violates this Agreement or applicable law.
Radius is a proximity-based peer-to-peer voice chat application. The App uses your device's location and microphone to enable real-time voice communication with nearby users. All voice data is transmitted directly between devices using end-to-end encryption (WebRTC DTLS-SRTP) — no audio is stored on or routed through our servers. Service availability depends on network conditions, device capability, Apple services, and third-party infrastructure, and may be interrupted or discontinued at any time without notice.
Location data is used solely to discover nearby users and is shared only as an approximate geohash cell identifier. Your precise coordinates are never stored on our servers. Microphone audio is transmitted directly to connected peers via encrypted WebRTC connections and is never recorded or stored. We do not collect personal information, account credentials, or usage analytics beyond basic connection metrics needed to operate the signaling service. See our Privacy Policy for full details. Our Privacy Policy is incorporated into this Agreement by reference.
Radius has zero tolerance for objectionable content and abusive users. Any user who transmits objectionable content or who harasses, threatens, or otherwise abuses another user will be immediately and permanently ejected from the service. Radius is a tool for real-time conversation with people near you. To keep it safe and usable, you agree not to use the App to:
We have zero tolerance for content that sexually exploits minors and will report such activity to the National Center for Missing & Exploited Children (NCMEC) and to law enforcement.
Radius is built and offered as a casual, for-fun way to chat with people who happen to be near you. It is not intended to be used for, and you agree not to use it for, any malicious, harmful, deceptive, or illegal purpose — including stalking, coordinating harassment, planning or facilitating crime, phishing, distributing malware, probing or attacking other users or infrastructure, harvesting data, or any form of surveillance. We built this for fun. Please use it that way.
You can report any user directly from within the App — the Peers list and incoming call screen each include a Report control that submits a report containing the reported session ID and timestamp to our moderation team. Reports go to contact@talkradius.com. We act on reports of objectionable content within 24 hours by removing offending content where applicable and ejecting the user who provided it from the service, at our sole discretion. Because voice is transmitted peer-to-peer in real time and is never recorded or stored on our servers, "removal" of an offending broadcast occurs automatically when the call ends; account-level removal of the offending user is performed by the moderation team upon report review. Users may also block any other user at any time using the in-app block feature; blocks are instant and persistent on your device. In cases involving credible threats, child sexual abuse material, or illegal activity, we may preserve available records and cooperate with law enforcement to the extent required or permitted by law.
Radius is designed as a hands-free communication tool. However, you are solely responsible for your safety and compliance with all applicable traffic laws. Do not interact with the App's interface while driving. Use voice controls and push-to-talk features to minimize distraction. By using the App, you acknowledge that driving requires your full attention and agree to use the App responsibly. You assume all risk associated with use of the App while in or around a moving vehicle.
You are solely responsible for all content and communications you transmit through the App, including voice communications. You represent and warrant that your use of the App and any content you transmit will not (a) violate any law, regulation, or third-party right, including intellectual property, privacy, and publicity rights; (b) contain unlawful, defamatory, infringing, obscene, or harmful material; or (c) solicit or facilitate any illegal act. You retain any rights you have in content you transmit; however, to the extent any content passes through our signaling infrastructure incident to operating the service, you grant us a limited, worldwide, royalty-free license to process such content solely as necessary to operate, maintain, and secure the App. We do not claim ownership of your voice communications and do not record them.
The App — including all software, designs, trademarks, logos, and content (excluding user-generated communications) — is owned by us or our licensors and is protected by United States and international copyright, trademark, and other intellectual property laws. "Radius" and the Radius logo are our trademarks. Except for the limited license granted in Section 3, this Agreement does not grant you any rights in our intellectual property, by implication, estoppel, or otherwise.
The App may use or integrate with third-party services, including but not limited to STUN/TURN relay servers, the Apple Push Notification service, map tile providers, and Apple platform services. These services are provided by third parties and are governed by their own terms and privacy policies. We are not responsible for the acts, omissions, availability, accuracy, or content of any third-party service. Your use of any third-party service is at your own risk.
We respect the intellectual property rights of others. If you believe that material available through the App infringes your copyright, you may submit a notification under the Digital Millennium Copyright Act ("DMCA") to contact@talkradius.com with the subject line "DMCA Notice." Your notice must include the elements required by 17 U.S.C. § 512(c)(3), including (i) your physical or electronic signature; (ii) identification of the copyrighted work claimed to be infringed; (iii) identification of the material claimed to be infringing and sufficient information to locate it; (iv) your contact information; (v) a statement of good-faith belief that the use is not authorized; and (vi) a statement, under penalty of perjury, that the information in the notice is accurate and that you are authorized to act on behalf of the copyright owner. We may terminate, in appropriate circumstances and at our sole discretion, the accounts of users we determine to be repeat infringers.
TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE APP AND ALL RELATED SERVICES ARE PROVIDED "AS IS," "AS AVAILABLE," AND "WITH ALL FAULTS," WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE. WE, ON BEHALF OF OURSELVES, OUR AFFILIATES, AND OUR LICENSORS, EXPRESSLY DISCLAIM ALL WARRANTIES, INCLUDING WITHOUT LIMITATION THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, QUIET ENJOYMENT, ACCURACY, AND ANY WARRANTIES ARISING OUT OF COURSE OF DEALING, USAGE, OR TRADE. WE DO NOT WARRANT THAT THE APP WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE; THAT DEFECTS WILL BE CORRECTED; OR THAT THE APP IS FREE OF VIRUSES OR OTHER HARMFUL COMPONENTS. YOU ASSUME ALL RISK ARISING FROM YOUR USE OF THE APP, INCLUDING ANY INTERACTION WITH OTHER USERS. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF IMPLIED WARRANTIES, SO SOME OF THE ABOVE EXCLUSIONS MAY NOT APPLY TO YOU.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL RADIUS, ITS DEVELOPERS, OFFICERS, EMPLOYEES, AGENTS, LICENSORS, OR AFFILIATES BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, INCLUDING BUT NOT LIMITED TO DAMAGES FOR PERSONAL INJURY, DEATH, PROPERTY DAMAGE, VEHICLE ACCIDENTS, LOSS OF PROFITS, LOSS OF DATA, LOSS OF GOODWILL, SERVICE INTERRUPTION, COMPUTER DAMAGE, OR ANY OTHER INTANGIBLE LOSSES, ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT OR YOUR USE OF OR INABILITY TO USE THE APP, WHETHER BASED ON WARRANTY, CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, OR ANY OTHER LEGAL THEORY, AND WHETHER OR NOT WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR TOTAL CUMULATIVE LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE APP SHALL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US FOR THE APP IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM, OR (B) FIVE U.S. DOLLARS ($5.00). THE LIMITATIONS IN THIS SECTION APPLY EVEN IF ANY LIMITED REMEDY FAILS OF ITS ESSENTIAL PURPOSE. SOME JURISDICTIONS DO NOT ALLOW THE LIMITATION OR EXCLUSION OF CERTAIN DAMAGES, SO SOME OF THE ABOVE LIMITATIONS MAY NOT APPLY TO YOU.
To the maximum extent permitted by law, you agree to defend, indemnify, and hold harmless Radius, its developers, officers, employees, agents, licensors, and affiliates from and against any and all claims, damages, obligations, losses, liabilities, costs, and expenses (including reasonable attorneys' fees) arising out of or related to: (a) your use or misuse of the App; (b) your violation of this Agreement; (c) your violation of any third-party right, including intellectual property, privacy, or publicity rights; (d) your violation of any applicable law; or (e) any content or communications you transmit through the App. We reserve the right, at our own expense, to assume exclusive defense and control of any matter otherwise subject to indemnification by you, in which event you will cooperate with us in asserting any available defenses.
PLEASE READ THIS SECTION CAREFULLY. IT AFFECTS YOUR LEGAL RIGHTS.
(a) Informal Resolution. Before filing any claim, you agree to contact us at contact@talkradius.com and provide a brief written description of the dispute and your contact information. The parties agree to negotiate in good faith for at least sixty (60) days before initiating any formal proceeding.
(b) Agreement to Arbitrate. Except as set forth below, any dispute, claim, or controversy arising out of or relating to this Agreement or the App (each, a "Dispute") shall be resolved exclusively by binding individual arbitration administered by the American Arbitration Association ("AAA") under its Consumer Arbitration Rules, as modified by this Agreement. The arbitration shall be conducted by a single arbitrator. The seat of the arbitration shall be Harris County, Texas, though you may elect to participate by telephone or video, or to have the arbitration conducted based solely on written submissions for claims under $25,000. The arbitrator's decision shall be final and binding and may be entered as a judgment in any court of competent jurisdiction. The Federal Arbitration Act governs the interpretation and enforcement of this arbitration provision.
(c) Exceptions. Either party may (i) bring an individual action in small claims court; (ii) seek injunctive or equitable relief in a court of competent jurisdiction to prevent actual or threatened infringement or misappropriation of intellectual property rights; and (iii) file suit to compel arbitration as provided herein.
(d) Class Action Waiver. YOU AND RADIUS AGREE THAT EACH PARTY MAY BRING CLAIMS AGAINST THE OTHER ONLY IN AN INDIVIDUAL CAPACITY AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, CONSOLIDATED, OR REPRESENTATIVE PROCEEDING. The arbitrator may not consolidate more than one person's claims and may not otherwise preside over any form of class or representative proceeding. If this class action waiver is found unenforceable, the entirety of this Section 17 shall be null and void, but the remainder of the Agreement shall continue in force.
(e) Jury Trial Waiver. YOU AND RADIUS EACH WAIVE ANY RIGHT TO A TRIAL BY JURY in any proceeding arising out of or related to this Agreement, to the fullest extent permitted by law.
(f) Opt-Out. You may opt out of this arbitration agreement by sending written notice of your decision to opt out to contact@talkradius.com with the subject line "Arbitration Opt-Out" within thirty (30) days of your first installation of the App. Your notice must include your name, the device you installed the App on, and a statement that you are opting out of the arbitration agreement. If you opt out, the remainder of this Agreement continues to apply, and disputes will be resolved in the courts specified in Section 18.
(g) Survival. This Section 17 survives termination of this Agreement.
This Agreement is governed by the laws of the State of Texas and applicable U.S. federal law, without regard to conflicts-of-laws principles. For any dispute not subject to arbitration under Section 17, you and Radius submit to the exclusive jurisdiction of the state and federal courts located in Harris County, Texas, and waive any objection based on inconvenient forum. The United Nations Convention on Contracts for the International Sale of Goods does not apply to this Agreement.
This Agreement is between you and Radius only, and not with Apple Inc. ("Apple"). Radius, not Apple, is solely responsible for the App and the content thereof. You acknowledge that:
The App and related technology may be subject to U.S. export-control laws, including the U.S. Export Administration Regulations and economic sanctions programs administered by the Office of Foreign Assets Control ("OFAC"). You agree to comply with all applicable export-control and sanctions laws, and you represent that you are not located in, under the control of, or a national or resident of any country subject to a U.S. Government embargo, and that you are not listed on any U.S. Government list of prohibited or restricted parties (including the OFAC Specially Designated Nationals List or the U.S. Department of Commerce Denied Persons List).
This Agreement is effective until terminated. We may suspend or terminate your access to the App at any time, with or without notice, for any reason, including if we believe you have violated this Agreement or engaged in conduct harmful to other users or the service. You may terminate this Agreement at any time by deleting the App from your device and ceasing all use. Upon termination, the license granted in Section 3 immediately ends and you must remove all copies of the App from your devices. Sections 5, 10–20, and 23–24, and any provision that by its nature should survive termination, will survive.
We may modify this Agreement at any time by posting the revised version in the App or at talkradius.com/terms. The revised Agreement is effective upon posting, and your continued use of the App after the revised version is posted constitutes your acceptance of the changes. If a change materially reduces your rights, we will use reasonable efforts to provide additional notice, such as an in-app notification. If you do not agree to any change, you must stop using the App and uninstall it.
We may provide notices to you via in-app notification, push notification, or by posting to talkradius.com. You consent to receive such notices electronically. You may send notices to us at contact@talkradius.com. Legal notices to Radius must also be sent to contact@talkradius.com with the subject line "Legal Notice" to be effective.
(a) Assignment. You may not assign or transfer this Agreement or any of your rights or obligations under it, in whole or in part, without our prior written consent, and any attempted assignment in violation of this Section is void. We may freely assign this Agreement without your consent. This Agreement binds and benefits the parties' permitted successors and assigns. (b) Severability. If any provision of this Agreement is held to be invalid, illegal, or unenforceable by a court of competent jurisdiction or arbitrator, that provision shall be enforced to the maximum extent permissible and the remaining provisions will remain in full force and effect. (c) No Waiver. Our failure to enforce any provision of this Agreement is not a waiver of that provision or of our right to enforce it later. A waiver is effective only if in writing and signed by an authorized representative of Radius. (d) Entire Agreement. This Agreement, together with the Privacy Policy, constitutes the entire agreement between you and Radius regarding the App and supersedes all prior or contemporaneous agreements, proposals, communications, and understandings, whether written or oral, relating to its subject matter. (e) Force Majeure. We will not be liable for any failure or delay in performance caused by events beyond our reasonable control, including acts of God, war, terrorism, civil unrest, labor disputes, pandemic, government action, internet or telecommunications failure, or interruption of third-party services. (f) Relationship of the Parties. The parties are independent contractors. Nothing in this Agreement creates any agency, partnership, joint venture, or employment relationship. (g) Headings & Interpretation. Headings are for convenience only and do not affect interpretation. "Including" means "including but not limited to."
