Terms of Service

Effective 7 September 2026.

These Terms describe the Service as it actually works today, including the parts that are still limited. Where a limit exists we say so plainly rather than describing a capability we have not built.

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"). We publish BuffUp under our Derusty brand, so our email and our website both use derusty.com.

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.

Your privacy is covered separately by the Privacy Policy, which forms part of these Terms. If you provide reviews as a teacher, the Teacher Agreement also applies and prevails over these Terms where they conflict.

2. What the Service does

The Service is a marketplace. Dancers ("Students") upload video of their practice or competition dancing and invite an instructor ("Teacher") to review it. The Teacher watches the video and 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.

We are the marketplace, not the reviewer. We do not produce feedback, do not check it before it reaches you, and do not stand behind it. Clause 6 sets out what that means in practice, and it is the most important clause in this document.

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 when you sign up and refuse accounts below 18. We do not verify it against a document — we rely on what you tell us, and giving us a false date is a breach of these Terms.

3.2 We know this excludes junior competitors, who are a real part of the dance community. It is a deliberate choice for this phase: serving under-18s properly requires verifiable guardian consent under section 9 of India's Digital Personal Data Protection Act, 2023, and equivalent protections under GDPR Article 8, together with the account and consent machinery that goes with them. We would rather exclude minors than handle their data badly. If we introduce a guardian-consent route later, 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 under any applicable law or by a previous termination.

4. Accounts and approval

4.1 Registration is currently gated. Creating an account places you in a queue; you cannot use the Service until we approve you. We may approve or decline at our discretion, and we are not obliged to give reasons.

4.2 Authentication is handled by our identity provider (Clerk). You are responsible for your 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 — meaning: storing your video, streaming it to the Teacher you invited, and showing you the feedback. The licence 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. Separately from your video, a review produces structured data: the tags and rubric criteria a Teacher selects, the scores they give, timestamps, and the dance style, focus and level recorded on the submission. This data describes movement and technique, not you. We use it to operate, analyse and improve the Service, including building and training move-recognition and review-quality models, and we may keep and use it after your account closes. It is part of what the Service is, so it is not optional — see section 6 of the Privacy Policy for exactly what this covers and what it does not.

5.4 Your video, audio and written comments are different. These identify you, so we do not train models on them unless you tell us we may. We ask at sign-up, with nothing pre-selected, and you can change the answer at any time in your account settings. If you have not answered, the answer is no. Switching it off does not delete anything or reduce the Service; it stops future training use. Full detail in section 6 of the Privacy Policy.

5.5 What you promise about what you upload. You warrant that you own or have the rights to the video; that uploading it breaches nobody's rights; and that 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. Partner dance means your video will usually contain somebody else. They are not a party to these Terms, may not have an account, and may not know the footage exists. Getting their agreement before you upload is your responsibility under clause 5.5. If someone in your video objects, write to buffup@derusty.com; we will erase the video and the feedback on it, 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 have no mechanism to evaluate whether a review was good, and we do not adjudicate disagreements about it. We will not act as arbiter between a Student and a Teacher on the substance of a review, 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 we make no representation about any Teacher's competence or suitability. Choosing a Teacher — or accepting one assigned by the "Surprise me" matching feature — is your decision and your risk.

6.5 Physical risk. Dance is physical activity and carries a risk of injury. Feedback may suggest changes to technique, posture, weight transfer or partnering. It is given without seeing you in person, without knowing your medical history, and without supervision. 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.

6.6 A short reminder of this clause appears on the upload screen, so it is in front of you when it matters and not only behind a link.

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.

7.2 "Surprise me" assigns a Teacher for you based on the budget band you choose and, where possible, your genre. The assignment is automated. 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 — never partially, never in progress.

7.4 We do not set a delivery deadline. If 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. During this phase we do not take payment. 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 — Teacher tier prices, budget bands, and the amount on the invite button — are indicative of the intended pricing model and are not charged. We know that is confusing and we are fixing the interface. Until we say otherwise in writing, treat every price on the Service as illustrative.

9.3 When charging begins we will give you advance notice, publish payment terms covering fees, our commission, holds, releases and refunds, and obtain any consent required. Nothing in these Terms authorises us to charge you today.

9.4 Any arrangement you make to pay a Teacher outside the Service is entirely between the two of you. We are not a party to it, take no commission on it, and accept no responsibility for it.

10. Availability

The Service is provided as-is and as-available. It is an early-stage product under active development. We do not promise uptime, and we may change, suspend, limit or withdraw any part of it — including features you rely on — 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 Two different actions. Remove takes a submission off your dashboard and leaves everything in place — your Teacher keeps their copy, and the review stays on record. Erase destroys the content: the video is deleted from our video provider, voice notes are deleted from storage, and the written comments, your title and the Teacher's overall note are removed, for you and for the Teacher.

12.3 Erasing keeps the skeleton of the record. The submission row itself survives, without its content: the status, which Teacher reviewed it, when, and the numeric rubric scores. A completed review is a record of a transaction between two people, and one party should not be able to rewrite the other's history — but that reasoning is about the record, and it was never a reason to keep your video. 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 — the video, the voice notes and the written feedback — is erased no sooner than 30 days and no later than 60 days after upload, whether or not you ask us. The clock runs from upload and does not restart. Your Teacher loses access at the same moment you do.

The 30-day minimum is a commitment: nothing is deleted before then. Within the window we may delete sooner than the maximum, and the only reason we will do so is managing storage cost. 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.

12.5 Closing an account. Erasing your 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 video, voice notes and written comments are erased. We may also close an account ourselves under clause 11.

What survives a closure, and why: the reviews themselves, without their content — status, which Teacher, when, and the numeric scores. Reviews you gave as a Teacher stay readable to the Students who received them, shown as "Deleted account", because that feedback is theirs and not ours to withdraw. We keep no name or email against any of it. Our access log (Privacy Policy §13) also keeps its existing entries, which cannot be edited or deleted.

Once closed, the email address is free again and you can sign up from scratch. The new account is genuinely new: it has no link to the old one and no access to anything from it.

12.6 Video and voice notes are served through short-lived signed links that expire after two hours, are issued per view, and are locked to the network address they were issued to — so a forwarded or cached link does not play somewhere else. Please still avoid sharing 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, and nothing here limits them.

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 — which, while clause 9.1 applies, is nil.

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, entirely at our discretion and without any obligation, provide records of what happened on the Service. This does not make us a mediator, and it 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 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.
