Commercial register: Canton of Thurgau
Effective: July 2026
1. Scope
These Terms govern the use of the platform "Roundwork AI" (hereinafter "Platform"), operated by Melzer Labs, Gaissbergstrasse 2, CH-8280 Kreuzlingen, UID CHE-217.593.064 (hereinafter "Operator").
By registering or using the Platform, users accept these Terms.
2. Definitions
- Platform: The Roundwork AI web application, including all subdomains and API services.
- Partner (Instructor): A natural or legal person offering teaching or coaching services through the Platform.
- Student: A natural person booking and paying for services through the Platform.
- Credits: Time-based units (1 credit = 30 minutes) used for lesson bookings.
- Recommendation: Content (a star rating, text, and an optional photo) that a Student publishes about an Instructor on that Instructor's page.
- Referral Program: The optional feature described in §6a that lets a Student share a referral link for an Instructor and earn Credits for qualifying referred bookings.
3. Registration and Accounts
3.1. Registration is required to use the Platform. Registration must be completed with accurate and complete information.
3.2. Each user may maintain only one account. Access credentials must be kept confidential.
3.3. The Operator reserves the right to suspend or delete accounts for violations of these Terms.
4. Platform Services
4.1. The Platform facilitates teaching and coaching services between Partners and Students.
4.2. The Operator does not provide teaching or coaching services. The contractual relationship for the service exists between Partner and Student.
4.3. The Operator provides the technical infrastructure: booking system, payment processing, calendar integration, and communication tools.
4.4. Permitted partner services. Partners may offer only lawful teaching and coaching services through the Platform. Offers in business categories restricted or prohibited by Stripe or applicable law are not permitted. The Operator may suspend partner accounts for violations without prior notice.
4.5. Payment processor and merchant of record. Stripe acts solely as the regulated payment processor for transactions made through the Platform and is not a party to the underlying teaching contract. Credit-pack purchases are only available once the Partner has completed Stripe Connect Express onboarding; payments are routed via Stripe Connect destination charges directly to the Partner's connected Stripe account, so the Partner is the merchant of record both for the credit-purchase payment and for the underlying lesson. The Operator only deducts its platform commission via `application_fee_amount`. Until the Partner is Connect-ready, students may join the Partner's interest list or, where the Partner has configured trial lessons, book free trial lessons; paid credit-pack purchases are not available.
4a. On-site Lessons
4a.1. Scope. This section applies when a Partner offers lessons at a physical location (e.g., the Partner's studio or premises, the Student's address, or another mutually agreed location) rather than online.
4a.2. Address disclosure. The full street-level address of an on-site lesson is disclosed only after a Student has a confirmed booking with the Partner or an active credit balance scoped to that Partner. Before booking, only approximate location information (city or district) is shown publicly so that Students can discover relevant Partners. Where the lesson takes place at the Student's address, the Student is responsible for providing accurate location information to the Partner; the Operator does not store the Student's home address beyond what the Student or Partner enters into the booking.
4a.3. Host responsibilities. The party providing the lesson location (Partner or Student) is responsible for ensuring the premises are safe, accessible, lawful for the intended use, and adequately insured. The Operator does not inspect, certify, license, or accept liability for any lesson location and is not a party to any rental, sublet, or usage arrangement at that location.
4a.4. Student conduct. Students must respect the Partner's premises and any house rules communicated by the Partner, arrive and leave at the agreed time, and may not bring additional persons without prior agreement. The Partner may decline service and let the corresponding credit be consumed under §7.2 if a Student materially breaches these expectations.
4a.5. No employment or agency relationship. On-site lessons do not create an employment, agency, or rental relationship between the Operator and the Partner or Student. Liability for damage to property or persons at the lesson location lies with the parties involved under applicable Swiss law.
4b. User-Generated Recommendations
4b.1. What they are. Signed-in Students may publish Recommendations on an Instructor's page. Recommendations are an optional feature and are not required to book lessons.
4b.2. Your responsibility for content. You may publish only Recommendations that reflect your genuine experience. You must not publish content that is unlawful, false or misleading, defamatory, harassing, obscene, that infringes intellectual-property or privacy rights, that discloses confidential information, or that contains personal data of third parties without their consent. You are responsible for the content you submit.
4b.3. Ownership and licence. You retain ownership of the Recommendation content you submit. You grant the Operator and the Instructor concerned a worldwide, non-exclusive, royalty-free licence to host, store, reproduce, resize and reformat, display, and distribute that content within the Platform and its Learner Advocacy features for as long as the Recommendation remains published. This licence ends when the Recommendation is removed, except for copies already shared or downloaded by third parties and for reasonable backup or legal-compliance retention.
4b.4. Moderation and removal. Recommendations are, by default, held for Instructor moderation before publication. The Instructor may publish, hide, or remove Recommendations on their page, and the Operator may remove any content that violates these Terms or applicable law. You may remove your own Recommendation at any time.
4b.5. Minors. If you are under the applicable age of digital consent (see the Privacy Policy), you may publish a Recommendation or a personal photo only with the authorization of a parent or legal guardian.
5. Partner Subscription and Platform Fee
5.1. Partners subscribe to a monthly or annual plan (Starter, Pro, or Scale) to use the Platform for service offerings and booking management.
5.2. A percentage-based platform fee (commission) applies to student payments. The rate depends on the Partner's active subscription plan.
5.3. Payment processing is handled by Stripe. Stripe processing fees are treated separately from the platform commission.
5.4. Automatic renewal. Partner subscriptions renew automatically at the end of each billing period (monthly or annual) at the then-current price for the selected plan unless cancelled in time. The price and billing interval shown at checkout apply to the first charge after any free trial; subsequent renewals use the list price in effect at renewal unless you change plan or cancel.
5.5. Free trial. New partner subscriptions include a 14-day free trial. If you cancel before the trial ends, you will not be charged. If you do not cancel before the trial ends, the subscription converts to a paid plan and renews automatically under §5.4.
5.6. How to cancel before renewal. You may cancel at the end of the current billing period via the in-app “Cancel at period end” control or the Stripe customer portal (Manage subscription). Cancellation takes effect at period end as described in §11.2. Deleting your account cancels immediately without refund for the remainder of the period (§11.1).
6. Credit System
6.1. Students purchase credit packages that are scoped per Partner. Credits expire 12 months from the date of purchase.
6.2. 1 credit equals 30 minutes of lesson time. Bookings consume credits proportional to duration.
6.3. Unused credits are not refundable as cash.
6a. Referral and Advocacy Program
6a.1. Program. Students may share a personal referral link for an Instructor and earn Credits when a referred person books a qualifying lesson with that Instructor. Participation is optional.
6a.2. Reward. The current reward is 0.25 Credit per qualifying attributed booking, capped at one reward per referred Student per referral link (repeat or series bookings by the same referred Student do not generate additional rewards). Trial (free) lessons and bookings you make for yourself do not qualify. A reward is added to your Credit balance with the relevant Instructor after the booked lesson's start time has passed, provided the booking has not been cancelled.
6a.3. Nature of rewards. Referral Credits have no cash value, are not redeemable for cash, and are not transferable. Once added, they are scoped to the relevant Instructor and can be redeemed for bookings like other Credits under §6.
6a.4. Attribution and anti-abuse. Rewards depend on the Operator attributing the booking to your referral link. Self-referrals, creating fake accounts or bookings, and any manipulation or circumvention of attribution or the reward cap are prohibited. The Operator may withhold, reverse, or cancel rewards earned through ineligible bookings, fraud, or abuse, and may suspend participation for violations.
6a.5. Changes to the program. The Operator may modify, suspend, or discontinue the Referral Program, or change the reward amount and eligibility rules, at any time with reasonable notice. Rewards already validly earned and credited are not affected.
7. Booking and Cancellation
7.1. Bookings are made through the Platform booking system. A booking is confirmed when saved in the system.
7.2. Cancellation policy: Each Partner sets the cancellation notice window applicable to their own lessons (default: 24 hours). If a Student cancels at least the number of hours configured by the Partner before the lesson start time, the credits are fully restored. Cancellations made after that window forfeit the credits. The cancellation notice window applicable to a given booking is shown on the Partner's booking page and in the booking confirmation, so the Student can verify it before purchase and before each booking.
7.3. Cancellations by the Partner always result in full credit restoration.
8. Payment Terms
8.1. Payments are processed via Stripe. By making a purchase, users accept Stripe's terms of service.
8.2. Prices displayed at checkout are the final amounts charged to you. No additional taxes are added on top at payment unless explicitly stated on the checkout page.
8.3. Partners receive payouts through Stripe Connect. Payout frequency follows Stripe settings and the partner agreement.
8.4. Tax / MWST (Operator and Partners). Melzer Labs (the Operator) is not registered for Swiss VAT (Mehrwertsteuer / MWST) and does not charge MWST on platform subscription fees at the current time. Partner lesson and credit prices are set by Partners and processed via Stripe Connect destination charges. Where a Partner is registered for Swiss VAT, the Partner enables this in their account settings, configures Stripe Tax on their connected Stripe account, and Stripe Tax then automatically (i) splits the gross price the Student sees into a net amount plus MWST, (ii) issues a Stripe invoice in the Partner's name with the Partner as merchant of record, and (iii) reports MWST against the Partner's tax registration; the Student is never asked to pay anything in addition to the gross price displayed at checkout. Where a Partner is not VAT-registered, no MWST is charged. The Operator pays Stripe Tax service fees on MWST-collected transactions and does not deduct them from the Partner's payout. If the Operator becomes liable to register for MWST in the future, applicable taxes will be shown at checkout before you pay.
8.5. Settlement and merchant-of-record assignment. Credit-pack purchases are settled exclusively through Stripe Connect destination charges: funds are routed directly to the Partner's verified, payout-enabled Stripe Connect account, and the Operator deducts its platform commission via `application_fee_amount`. The Partner is the merchant of record both for the credit-purchase payment and for the underlying teaching service (§4.2, §4.5). Stripe acts only as the regulated payment processor and is not a party to the contract between Student, Partner, and Operator. Where a Partner has not completed Stripe Connect onboarding, no paid credit-pack purchase can take place; the Partner profile then surfaces only the interest list and, where configured, free trial lessons.
9. Liability
9.1. The Operator is not liable for the quality, legality, or availability of services offered by Partners.
9.2. The Operator's liability is limited to intent and gross negligence, to the extent permitted by law.
9.3. The Operator does not guarantee uninterrupted availability and is not liable for technical disruptions, data loss, or third-party service failures (e.g., Stripe, Google).
10. Intellectual Property
10.1. All rights to the Platform, including software, design, and trademarks, remain with the Operator.
10.2. Partners retain rights to their own content (text, images, descriptions) but grant the Operator a non-exclusive license to display such content on the Platform.
10.3. Students retain ownership of the Recommendation content they submit and grant the Operator and the relevant Instructor the limited licence set out in §4b.3 for hosting and displaying that content within the Platform's Learner Advocacy features. Users remain responsible for content they share through external channels, and the Operator cannot retract material a user has already shared or downloaded outside the Platform.
10a. Right of Withdrawal (Consumers in the EU / EEA)
10a.1. If you are a consumer resident in the EU or EEA, you have the right to withdraw from a distance contract within 14 days without giving any reason, starting the day after the contract is concluded.
10a.2. Digital services and immediate performance: The Platform provides digital services that are made available to you immediately upon purchase (lesson bookings, credit purchases, subscription activation). To exercise these services without delay, you must expressly agree at checkout that provision begins before the end of the 14-day withdrawal period and that you acknowledge the loss of your right of withdrawal upon full provision by the Operator. The waiver checkbox presented during checkout constitutes this express consent.
10a.3. Non-waived withdrawal: If you do not waive your withdrawal right, you may cancel by sending an unambiguous declaration (email to legal@roundwork.ai stating your name, account email, and the purchase you wish to cancel) within 14 days of purchase. Where Credits have not yet been redeemed and performance has not yet begun, the purchase price will be refunded via the original payment method within 14 days.
10a.4. Users resident in Switzerland or outside the EU/EEA have no statutory right of withdrawal, but the cancellation rules in §7 and §11 of these Terms apply.
11. Termination
11.1. Students may delete their account at any time. Unused credits expire upon account deletion.
11.2. Partners may cancel their subscription at the end of the current billing period. Outstanding bookings and credit obligations remain in effect. The Platform may pause new credit package sales when a Partner subscription is not active; Students may continue to redeem prepaid credits for bookings until they expire under §6.
11.2a. Immediate cancellation on account deletion. Notwithstanding §11.2, when a Partner deletes their account under §11.1, the Operator cancels any active Stripe subscription immediately (not at the end of the current billing period). No refund or pro-rated credit is issued for the unused remainder of the current billing period. This applies whether the Partner is on the free trial (§5.5), a monthly plan, or an annual plan. The ordinary period-end cancellation path described in §5.6 and §11.2 (via the in-app "Cancel at period end" control or the Stripe customer portal) remains available and continues to take effect at the end of the current billing period.
11.3. The Operator may suspend accounts immediately for serious violations of these Terms.
12. Changes to Terms
12.1. The Operator reserves the right to modify these Terms at any time. Changes will be communicated via email or in-app notification.
12.2. Continued use of the Platform after changes take effect constitutes acceptance of the updated Terms.
13. Governing Law and Jurisdiction
13.1. Swiss law applies.
13.2. The place of jurisdiction is Kreuzlingen, Switzerland, to the extent permitted by law.
