1. Agreement to These Terms
These Terms of Service ("Terms") form a binding legal agreement between you and the operator of Cavin ("Cavin", "the App", "we", "us", or "our") governing your access to and use of the Cavin mobile application and all associated features and content.
Cavin is a figure skating application that pairs tools for choreography planning with a technique-oriented content community.
By downloading, installing, or using Cavin, you confirm that you have read, understood, and agree to be bound by these Terms and by our Privacy Policy, which is incorporated here by reference. If you do not agree, you must not use the App.
Contact: service@cavin.info
2. Eligibility
You must be at least 18 years of age to use Cavin. On first launch you are required to confirm this. By continuing past the age confirmation screen, you represent and warrant that you are 18 or older, that you have the legal capacity to enter into this agreement, and that you are not barred from using the App under the laws of your jurisdiction.
If we determine that you do not meet these requirements, we will terminate your access without notice.
3. Accounts
3.1 Creating an Account
An account is required to use Cavin. You may sign in using Sign in with Apple. A profile is generated with a nickname and avatar that you may edit. You agree to provide accurate information and to keep your profile current.
3.2 Account Security
You are responsible for all activity that occurs under your account and for maintaining the security of the device and Apple ID used to access it. Notify us at service@cavin.info if you suspect unauthorized use.
3.3 One Person, One Account
Accounts are personal. Do not share, sell, rent, or transfer your account, and do not create an account on behalf of another person or to evade an enforcement action.
3.4 Deleting Your Account
You may delete your account at any time from Settings. Deletion is permanent, erases your local data, and forfeits any unspent coins without refund.
4. License to Use the App
Subject to your compliance with these Terms, we grant you a limited, personal, non-exclusive, non-transferable, non-sublicensable, revocable license to install and use one copy of Cavin on a device you own or control, solely for your personal, non-commercial use.
You may not: copy, modify, translate, or create derivative works of the App; reverse engineer, decompile, or disassemble any part of it except to the extent that applicable law expressly permits; remove or obscure any proprietary notice; rent, lease, lend, sell, or sublicense the App; use automated scripts, bots, scrapers, or crawlers to access or extract content; circumvent any technical limitation, rate limit, or access control; or use the App to build a competing product.
5. Tool Use
Cavin provides tools that let you work with a piece of music and mark timing points within it in order to plan choreography.
You are responsible for ensuring you hold the rights necessary to use any audio you import. Cavin provides built-in sample content for use within the App; that content is licensed for in-App use only and may not be extracted, redistributed, or used in any other production.
The projects you create with these tools belong to you. You may use them freely for your own training, coaching, and choreography purposes.
The App is a planning aid, not a coaching authority. Any output of the tools is provided for your own reference. You are responsible for your own safety on the ice and for the safety of anyone you coach.
6. User Generated Content
6.1 Your Ownership
You retain ownership of the content you create and publish, including posts, comments, media, and messages.
6.2 License You Grant Us
By publishing content in Cavin, you grant us a worldwide, non-exclusive, royalty-free, transferable, sublicensable license to host, store, reproduce, adapt for display, distribute, and publicly display that content for the purpose of operating, securing, promoting within the App, and improving the service. You also grant other users the right to view your content through the App's normal functionality. This license ends when you delete the content or your account, subject to reasonable delays in backup and moderation systems and to content others have already lawfully shared.
6.3 Your Representations
You represent and warrant that you own or have all rights necessary to publish your content, that it does not infringe any third party's intellectual property, privacy, or publicity rights, and that it complies with these Terms and all applicable law.
6.4 No Obligation to Host
We are not obligated to store, display, or maintain any content and may remove or restrict any content at our discretion, particularly where it violates these Terms or creates legal risk.
7. Community Rules and Prohibited Conduct
Cavin exists for technical exchange about skating. Before your first publication you must review and accept the Community Guidelines.
The following are prohibited anywhere in the App, including posts, comments, images, videos, avatars, nicknames, and messages:
1. Child safety violations. Any content or conduct involving child sexual abuse or exploitation, including CSAM in any medium, sexualization of minors, grooming, solicitation, sextortion, or the normalization of sexual interest in minors. This carries immediate and permanent termination and referral to NCMEC and law enforcement. Because skating content may feature young athletes, sexualizing commentary about or framing of such content is treated as a severe violation.
2. Sexual and adult content. Pornography, sexually explicit imagery, or sexual solicitation of any kind.
3. Harassment and hate. Bullying, targeted abuse, threats, intimidation, stalking, or attacks based on race, ethnicity, national origin, religion, disability, gender, sexual orientation, or any other protected characteristic.
4. Violence and self-harm. Incitement to violence, glorification of violent acts, terrorist content, or promotion of self-harm, disordered eating, or dangerous weight control practices. We enforce this rule strictly.
5. Privacy violations. Publishing another person's home address, phone number, financial details, government identifiers, or private communications, or posting identifiable content featuring another person, including a minor, without appropriate consent.
6. Impersonation and deception. Posing as another person or organization, or misrepresenting your affiliation or credentials.
7. Intellectual property infringement. Uploading music, video, or imagery you do not have the right to distribute.
8. Spam and commercial abuse. Repetitive posting, mass unsolicited messaging, engagement manipulation, artificial account creation, or unauthorized advertising.
9. Off-platform payment solicitation. Requesting or directing payments outside the App's in-app purchase system.
10. Illegal activity. Promoting or facilitating anything unlawful, including the sale of controlled substances, weapons, or fraudulent services.
11. Security abuse. Distributing malware, attempting unauthorized access, probing or testing system vulnerabilities, or interfering with the App's normal operation.
Cavin contains no dating, matchmaking, anonymous pairing, nearby discovery, ranking, contest, or prize mechanics. Attempting to repurpose the community features for these purposes violates these Terms.
8. Reporting, Moderation, and Enforcement
Every piece of content and every user profile carries a Report control offering defined reason categories, along with a Block control.
Reporting hides the content from your view immediately and queues it for review, typically within 24 hours. Blocking removes all of that user's content from your view instantly. Blocked users can be reviewed and unblocked from Settings.
Depending on severity, frequency, and intent, enforcement may include removal of content, limitation of features, temporary suspension, or permanent termination of your account. Child safety violations result in immediate permanent termination without warning.
Where we take action against your content or account, we aim to notify you and to offer a means of appeal by writing to service@cavin.info, except where notice is prohibited by law or would compromise a child safety or criminal investigation.
Abusing the reporting system through false or malicious reports is itself a violation. Reports submitted in good faith will never be penalized.
9. Content Tags and Interactions
Cavin lets you apply preset descriptive tags to community content and interact with it through simple actions such as liking and saving.
These interactions describe the character of the content itself. They are not a score, a ranking, or a judgment of any person's appearance or ability. Cavin publishes no leaderboards, no rankings, no scores, no contests, and grants no rewards for any interaction.
Manipulating these interactions through multiple accounts or automated means is prohibited.
10. Communities and Messaging
Communities in Cavin are public and open to join. Anything you post inside one is visible to its members.
Chat is an auxiliary tool supporting technical discussion, not a primary social feature. There is no global user search, no friend request system, and no way to reach users you share no community with.
Community creators are expected to keep their community on topic and to report violating content within it. We may remove communities that are dormant, duplicative, misleading, or used for prohibited purposes.
11. Coins and In-App Purchases
11.1 Nature of Coins
Coins are a consumable virtual item used solely to unlock digital functions inside Cavin. They have no monetary value, are not currency or a currency substitute, cannot be exchanged for cash, cannot be transferred or gifted to other users, cannot be withdrawn, and do not correspond to any physical goods or services.
11.2 Purchasing
Coins are sold in consumable packs through the Apple App Store or Google Play. All payments are processed by the platform. Prices are shown in your local currency before purchase and may change at any time.
11.3 Spending
Coins are spent to unlock certain digital functions inside the App. Each transaction displays a confirmation showing the cost and your current balance, and is added to your transaction record. Core use of the App, including browsing, using the tools, posting, and messaging, remains free.
11.4 Refunds
Because coins are consumable and delivered immediately, purchases are final. Refund requests are handled exclusively by Apple or Google under their published policies. The Restore Purchases control is provided for compliance; consumable items are not restorable.
11.5 Forfeiture
Unspent coins are forfeited without compensation if you delete your account, if your account is terminated for a violation of these Terms, or if the service is discontinued as described in Section 15.
11.6 No Gambling
Cavin contains no loot boxes, no randomized rewards, no prize draws, and no probability-based mechanics of any kind.
12. Intellectual Property
The App itself, including its software, interface design, layouts, graphics, icons, built-in sample content, the Cavin name, and all associated logos, is owned by us or our licensors and is protected by copyright, trademark, and other laws. These Terms grant you no rights in our intellectual property beyond the limited license in Section 4.
If you send us suggestions or feedback, we may use them freely and without obligation, compensation, or attribution.
Copyright complaints should be sent to service@cavin.info with identification of the work, the location of the infringing material, your contact details, a good faith statement, a statement of accuracy, and your signature. Accounts of repeat infringers will be terminated.
13. Privacy
Your use of Cavin is subject to our Privacy Policy, which describes what information is collected, how it is used and shared, and the rights available to you. Cavin is built on a local-first architecture in which the majority of your data remains on your device, and the App does not collect location data of any kind. Please read the Privacy Policy before using the App.
14. Disclaimers
The App is provided "as is" and "as available", without warranty of any kind. To the fullest extent permitted by law, we disclaim all warranties, express, implied, or statutory, including implied warranties of merchantability, fitness for a particular purpose, title, accuracy, and non-infringement.
We do not warrant that the App will be uninterrupted, timely, secure, or error-free, that defects will be corrected, or that any output of the tools will be free from imprecision.
Physical safety. Figure skating is a physically demanding activity carrying inherent risk of injury. Cavin is a planning and reference tool only. It does not provide coaching, medical, or safety advice. Always train within your ability, under qualified supervision where appropriate, and consult a medical professional before undertaking new physical activity.
User content. We do not endorse and are not responsible for content published by users. Any advice or opinion shared in the community reflects the views of its author alone.
15. Limitation of Liability
To the maximum extent permitted by applicable law, we and our officers, employees, and agents will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenue, data, goodwill, or content, arising from or related to your use of or inability to use the App, whether based in contract, tort, negligence, strict liability, or any other theory, and whether or not we were advised of the possibility of such damages.
Our total aggregate liability for all claims relating to the App will not exceed the greater of the amount you paid us in the twelve months preceding the event giving rise to the claim, or fifty United States dollars.
Some jurisdictions do not allow the exclusion of certain warranties or the limitation of certain damages. In those jurisdictions, our liability is limited to the smallest extent permitted by law, and nothing in these Terms limits liability for death or personal injury caused by negligence, for fraud, or for any other liability that cannot lawfully be excluded.
16. Indemnification
You agree to indemnify, defend, and hold harmless Cavin and its officers, employees, and agents from any claim, demand, loss, liability, damage, or expense, including reasonable legal fees, arising out of your content, your use of the App, your violation of these Terms or of any law, or your infringement of any third party's rights.
17. Modification, Suspension, and Termination
We may modify, suspend, or discontinue any feature of the App, in whole or in part, at any time. Where a change materially reduces functionality you rely on, we will give reasonable advance notice where practicable.
We may suspend or terminate your access immediately and without prior notice if you violate these Terms, if your conduct creates risk or legal exposure for us or other users, or if required by law.
You may stop using the App at any time and may delete your account from Settings.
Sections concerning content license survival, intellectual property, disclaimers, limitation of liability, indemnification, and dispute resolution survive termination.
18. Changes to These Terms
We may revise these Terms from time to time. The Last Updated date at the top of this document reflects the current version, which is always available in the App under Settings, then Terms of Use.
For material changes, we will provide prominent advance notice, such as an in-app notice or a launch screen prompt, before the revised Terms take effect. Continued use after the effective date constitutes acceptance. If you do not accept the revised Terms, you must stop using the App and may delete your account.
19. Governing Law and Dispute Resolution
19.1 Informal Resolution First
Before initiating any formal proceeding, you agree to contact us at service@cavin.info and attempt in good faith to resolve the dispute informally. Most concerns can be resolved this way within thirty days.
19.2 Governing Law
These Terms are governed by the laws applicable at our principal place of business, without regard to conflict of law principles. If you are a consumer resident in a jurisdiction whose law grants you the protection of mandatory local consumer rules, nothing in this section deprives you of those protections or of the right to bring proceedings in your local courts.
19.3 Individual Basis
To the extent permitted by law, disputes will be resolved on an individual basis. You agree not to participate in any class, collective, or representative action against us. This waiver does not apply where prohibited by applicable law.
20. General Provisions
Entire agreement. These Terms, together with the Privacy Policy and Community Guidelines, constitute the entire agreement between you and us regarding the App and supersede any prior understanding.
Severability. If any provision is held unenforceable, that provision will be limited or severed to the minimum extent necessary and the remaining provisions will remain in full force.
No waiver. Our failure to enforce any provision is not a waiver of our right to do so later.
Assignment. You may not assign these Terms without our written consent. We may assign them in connection with a merger, acquisition, or sale of assets.
Force majeure. We are not liable for failure to perform caused by events beyond our reasonable control.
Platform terms. Your use of the App is also subject to the terms of the Apple App Store or Google Play. Where those terms conflict with these Terms with respect to the platform relationship, the platform terms control. Apple and Google are not parties to these Terms and bear no responsibility for the App or its content, though Apple and its subsidiaries are third-party beneficiaries entitled to enforce these Terms against you.
Language. These Terms are drafted in English. Any translation is provided for convenience only, and the English version governs in the event of any discrepancy.
