Terms of Service
1. Who we are and what this is
BuffUp ("the Service") is operated by Adyota Ventures LLC, a Wyoming limited liability company, 30 N Gould St Ste N, Sheridan, WY 82801, USA ("we", "us"), under our Derusty brand.
These Terms are a contract between you and us. By creating an account or using the Service you accept them. If you do not accept them, do not use the Service.
The Privacy Policy forms part of these Terms. If you review as a teacher, the Teacher Agreement also applies and prevails where they conflict.
2. What the Service does
The Service is a marketplace. Dancers ("Students") upload video of their dancing and invite an instructor ("Teacher") to review it. The Teacher returns timestamped tags, written comments, voice notes and rubric scores. Everything is asynchronous; there are no live sessions. You may hold both roles on one account.
You can also upload a video of your own dancing and add your own notes to it, with no Teacher involved. Only you can see that video and those notes.
We are the marketplace, not the reviewer. We do not produce feedback, check it before it reaches you, or stand behind it. See clause 6.
3. Eligibility and age
3.1 You must be 18 or older to create an account. The Service is not directed to, and may not be used by, anyone under 18. We ask for your date of birth at sign-up and refuse accounts below 18. We rely on what you tell us, and giving a false date breaches these Terms.
3.2 This excludes junior competitors for now. If we open a route with guardian consent, we will say so before it opens.
3.3 If we learn that an account belongs to someone under 18, we will suspend it and delete the associated personal data, subject to clause 12.
3.4 You must also be legally able to enter into this contract, and not barred from the Service by law or by a previous termination.
4. Accounts and approval
4.1 Registration is currently gated. You cannot use the Service until we approve your account. We may approve or decline at our discretion, without giving reasons.
4.2 You are responsible for your sign-in credentials and for everything done through your account. Tell us promptly at buffup@derusty.com if you suspect unauthorised access.
4.3 Give us accurate information and keep it current. One account per person; do not share, sell or transfer it.
5. Your content
5.1 You keep ownership. Video you upload stays yours. Feedback a Teacher writes stays theirs, subject to the licence in the Teacher Agreement.
5.2 Licence to us: operating the Service. You grant us a worldwide, non-exclusive, royalty-free licence to host, store, transcode, reproduce and transmit your content only so far as needed to operate the Service: storing your video, streaming it to the Teacher you invited, and showing you the feedback. It lasts as long as we hold the content under clause 12. It does not permit us to publish your video, market with it, or make it public.
5.3 Structured review data. A review also produces structured data: the tags and rubric criteria a Teacher selects, the scores, timestamps, and the dance style, focus and level of the submission. It describes movement and technique, not you. We use it to operate, analyse and improve the Service, including training move-recognition and review-quality models, and may keep it after your account closes. It is part of the Service, so it is not optional. See section 6 of the Privacy Policy.
5.4 Your video, audio and written comments are different. We do not train models on them unless you tell us we may. We ask at sign-up with nothing pre-selected, an unanswered question counts as no, and you can change your answer at any time in your account settings without losing anything. See section 6 of the Privacy Policy.
5.5 What you promise about what you upload. You own or have the rights to the video; uploading it breaches nobody's rights; and every identifiable person in it has agreed to appear in it and to its being reviewed on the Service.
5.6 Dance partners and other people in your video. Getting their agreement before you upload is your responsibility under clause 5.5. If someone in your video objects, write to buffup@derusty.com and we will erase the video and its feedback as described in clause 12.
5.7 What you may not upload. Content that is unlawful, infringing, defamatory, hateful, sexually explicit, or that depicts a person under 18; content recorded where recording was not permitted; malware; or anything uploaded to harass someone.
5.8 Removal. We may remove content or suspend an account that we reasonably believe breaches these Terms. Where practical we will tell you why.
6. Feedback is opinion, not a guarantee
Read this clause.
6.1 Feedback on the Service is one instructor's professional opinion. It is not certified instruction, not an assessment recognised by any competition, federation or examining body, and not a guarantee of any result, competitive, technical or otherwise.
6.2 Teachers do their best; nobody promises an outcome. A Teacher agrees to review your video with reasonable skill and care within the scope you requested. Neither the Teacher nor we promise that the feedback will be correct, complete, useful, flattering, or what you hoped for.
6.3 We do not judge feedback quality. We do not adjudicate disagreements about a review or act as arbiter between a Student and a Teacher on its substance, and dissatisfaction with feedback is not by itself a basis for a claim against us.
6.4 We do not vet Teachers. Approval under clause 4.1 is an access decision, not an endorsement. We do not verify qualifications, experience, certifications, insurance or background, and make no representation about any Teacher's competence or suitability. Choosing a Teacher, or accepting one assigned by "Surprise me", is your decision and your risk.
6.5 Physical risk. Dance carries a risk of injury. Feedback may suggest changes to technique, posture, weight transfer or partnering, given without seeing you in person or knowing your medical history. It is not medical, physiotherapeutic or professional health advice. You act on it at your own risk, you are responsible for judging what is safe for your body, and you should consult a qualified professional before acting on anything that could affect your health or an existing injury. Do not use the Service for rehabilitation guidance.
7. How reviews work
7.1 A Teacher may accept or decline an invitation. Declining requires a reason, which we show you so you can invite someone else. Nobody is obliged to accept your invitation. If a Teacher you invited directly does not answer within 7 days, the invitation ends and you can invite someone else. This applies while the Service is free too.
7.2 "Surprise me" assigns a Teacher for you based on the budget band you choose and, where possible, your genre. If the assigned Teacher does not answer within 48 hours, it goes to another, up to three in all. We do not promise any particular Teacher, price point, or that a match will be found.
7.3 Feedback becomes visible to you only when the Teacher submits it.
7.4 The delivery deadline. When the delivery deadline is on, a Teacher who accepts has 14 days to submit, and we remind them before it passes. If they do not submit in time, the review is cancelled, and if you paid for it you are refunded in full automatically. See the Payment Terms, clause 6.
The deadline is always on once payments are live. While the Service is free we may switch it off. When it is off and a Teacher goes quiet, contact us at buffup@derusty.com and we will try to help, but we cannot compel anyone to complete a review.
7.5 Video uploads are capped at 5 minutes each. Other limits may apply and may change.
8. Acceptable use
Do not: use the Service unlawfully; harass, abuse or discriminate against another user; misrepresent who you are or your qualifications; scrape, crawl or bulk-extract content; attempt to access accounts, data or systems you are not authorised to reach; probe or test our security without written permission; interfere with the Service's operation; circumvent access controls; re-record, screen-capture, download, redistribute or publish another user's video or feedback; or use anything obtained through the Service to train a machine-learning model.
9. Money
9.1 The Service is currently free. No charge is made when you send an invite, and no money moves between Students and Teachers through the Service.
9.2 Prices shown in the interface are indicative and are not charged. Until we say otherwise in writing, treat every price on the Service as illustrative.
9.3 The Payment Terms set out how charging will work when it begins. They are published in advance and change nothing today. We will give you notice before charging begins. Nothing in these Terms authorises us to charge you today.
9.4 Any arrangement you make to pay a Teacher outside the Service is between the two of you. We are not a party to it and accept no responsibility for it.
10. Availability
The Service is provided as-is and as-available and is under active development. We do not promise uptime, and we may change, suspend, limit or withdraw any part of it, with or without notice. We will try to give notice of changes that materially reduce what you get.
11. Suspension and termination
11.1 You may stop using the Service and ask us to close your account at any time, by writing to buffup@derusty.com.
11.2 We may suspend or terminate your account if you breach these Terms, if we are required to by law, or if we discontinue the Service.
11.3 Clauses 5.2 (for content we still hold), 6, 12, 13, 14, 15, 16 and 18 survive termination.
12. What happens to your data and content
12.1 The Privacy Policy governs personal data. This clause is about content.
12.2 Remove and erase are different. Remove takes a submission off your dashboard and leaves everything in place, including your Teacher's copy. Erase destroys the content: the video, the voice notes, the written comments, your title and the Teacher's overall note, for you and for the Teacher.
12.3 Erasing keeps the record without its content: the status, which Teacher reviewed it, when, and the numeric rubric scores. You can erase a single submission from your dashboard, or everything you have uploaded from your account settings.
12.4 We delete everything within a fixed window. Every submission is erased no sooner than 30 days and no later than 180 days after upload, whether or not you ask. The clock runs from upload and does not restart, and your Teacher loses access at the same moment you do. Nothing is deleted before 30 days. If you want to keep your feedback, download it: every completed review has a Download link, and the file works offline and does not expire.
A video you upload for your own notes is deleted, with your notes on it, on the same schedule. You can delete it yourself at any time, and deleting it is permanent.
12.5 Closing an account. Erasing content does not close your account. Write to us and we will close it: your sign-in is deleted, your name, email and date of birth are removed, and your uploaded content is erased. We may also close an account under clause 11.
What survives a closure: the reviews without their content (status, which Teacher, when, the numeric scores). Reviews you gave as a Teacher stay readable to the Students who received them, shown as "Deleted account". We keep no name or email against any of it. Existing entries in our access log (Privacy Policy §13) also remain.
Records of money also survive, once there are any. The record of a transaction (what it was for, how much, and our payment provider's reference) is kept after your account is closed, because we are required to keep financial records. It holds no name, no email and nothing you uploaded.
Once closed, the email address is free again and you can sign up from scratch, with no link to the old account.
12.6 Video and voice notes play through short-lived links issued to you. Please do not share them.
13. Disclaimers
To the fullest extent permitted by law, the Service is provided "as is" and "as available", and we disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose, non-infringement, accuracy, and uninterrupted or error-free operation. We give no warranty as to any content or feedback provided by another user.
Nothing in these Terms excludes liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for anything else that cannot lawfully be excluded. If you deal with us as a consumer, you keep the rights your local consumer law gives you.
14. Limitation of liability
14.1 To the fullest extent permitted by law, we are not liable for indirect, incidental, special, consequential or punitive damages, or for loss of profits, opportunity, goodwill, data or anticipated savings.
14.2 We are not liable for: the content, accuracy or usefulness of any feedback; any act or omission of a Teacher or Student; any injury arising from acting on feedback (subject to clause 13); or any dispute between users.
14.3 Our total aggregate liability arising out of or relating to the Service is limited to the greater of US$100 and the total amount you have paid us in the 12 months before the claim.
14.4 Clauses 14.1 to 14.3 do not apply to liability that cannot lawfully be limited, including under clause 13.
15. Indemnity
You will indemnify us against claims, losses and reasonable costs arising from your breach of these Terms, your content, or your infringement of anyone's rights, including a claim by a person appearing in video you uploaded. We will notify you of any such claim and not settle it without your consent, not to be unreasonably withheld.
16. Disputes between users
Disputes between a Student and a Teacher are between them. We are not a party and take no position. We may, at our discretion, provide records of what happened on the Service. This does not make us a mediator and does not affect clause 6.3.
17. Changes to these Terms
We may update these Terms. For material changes we will give at least 30 days' notice by email or in the Service before they take effect. Continuing to use the Service after that means you accept the updated Terms; if you do not, close your account under clause 11.1.
18. Governing law and jurisdiction
These Terms are governed by the laws of the State of Wyoming, United States, without regard to its conflict-of-laws rules, and the state and federal courts located in Wyoming have exclusive jurisdiction. If you use the Service as a consumer resident elsewhere, this does not deprive you of the protection of mandatory consumer-protection law in your country of residence, or of the right to bring proceedings there where that law so provides.
19. General
19.1 These Terms, with the Privacy Policy, the Payment Terms and (for Teachers) the Teacher Agreement, are the entire agreement between us about the Service.
19.2 If a provision is unenforceable, the rest stands.
19.3 Not enforcing a provision is not a waiver of it.
19.4 You may not assign these Terms. We may assign them to a successor to our business, on notice.
19.5 Nobody other than you and us has any right to enforce these Terms.
20. Contact
