    (hereinafter “Coach” or “Provider”) and the client or contractual partner (hereinafter “Client”).
  2. These Terms apply to both consumers (§ 13 BGB) and entrepreneurs (§ 14 BGB), unless an explicit distinction is made in the respective provision.
  3. Deviating, conflicting, or supplementary terms and conditions of the Client shall only become part of the contract if and to the extent that the Provider has expressly agreed to their validity in writing.
  4. Should the legal form of the Provider’s business change in the future (e.g., conversion into a registered commercial business or a corporate entity), these Terms shall remain fully valid for all existing and future contractual relationships.

§ 2 Conclusion of Contract, Booking Methods & B2B Special Provisions

  1. 1:1 Sessions & B2C Offers: The presentation of services on the website, social media channels, or booking platforms does not constitute a legally binding offer. The contract is concluded upon appointment agreement via email, integrated booking tools (e.g., Google Appointment Schedules), or written booking confirmation by the Provider.
  2. Corporate Clients (B2B): For customized B2B corporate coaching or corporate workshops, the Provider will issue an individual offer (e.g., via Lexoffice). The contract is concluded upon written acceptance of the proposal (via email or signature) by the respective company.
  3. Personal Performance & Transferability: Booked appointments, packages, and workshop slots are personal and strictly non-transferable. A transfer to third parties is excluded unless agreed to by the Provider in writing on an individual basis.

§ 3 Scope of Services & Multi-Session Packages (e.g., 3-Session Package)

  1. The exact content and scope of the respective service derive from the service description of the chosen session, class, or workshop.
  2. Multi-Session Packages: If multi-session packages (e.g., 3-session packages) are purchased, they apply to the agreed number of individual sessions. The statutory limitation period (§ 195 BGB) of three years from the end of the year in which the package was purchased applies to the redemption of the sessions.

§ 4 Prices, Payment Terms & Small Business Status

  1. Prices: The prices stated at the time of contract conclusion shall apply. All prices are final prices in Euros (EUR).
  2. Small Business Status (Kleinunternehmerregelung): According to § 19 UStG (German Value Added Tax Act), no VAT is charged or displayed as a small business. Should the Provider transition to standard taxation in the course of the business relationship, statutory VAT will be displayed accordingly.
  3. Due Date: The fee for individual sessions and packages becomes due upon invoicing on the day the service is rendered or purchased. Payment is due within 7 days from the invoice date without deduction.
  4. Advance Payment Right: The Provider reserves the right to make the provision of services for new clients, group workshops, or packages conditional upon prior payment (advance payment).
  5. Payment Methods & Currency: Payment shall be made via bank transfer or through the payment service providers offered during the booking process (e.g., Stripe, PayPal). All payments must be made strictly in Euros (EUR). Any transaction, bank, or currency conversion fees arising from international or foreign currency payments shall be borne entirely by the Client.

§ 5 Important Health Disclaimer, Self-Determination & Liability Waiver

  1. No Medical Treatment: The services offered (breathwork, yoga, coaching) do not constitute medical, healing, or psychotherapeutic treatment and are at no time a substitute for diagnosis, advice, or treatment by a physician, psychiatrist, psychologist, or alternative practitioner (Heilpraktiker). No claims of cure or guarantees are made.
  2. Personal Responsibility & Contraindications: Participation is at the Client’s own risk. The Client confirms that they are in good physical and mental health. In the presence of contraindications—specifically cardiovascular conditions, high blood pressure, epilepsy, asthma, recent surgeries, increased intraocular pressure (glaucoma), pregnancy, or severe mental health conditions—participation in intensive breathing techniques (breathwork) and cold exposure (Wim Hof Method) is excluded or requires prior explicit medical clearance. Gentle formats (e.g., yoga) are generally permitted after prior consultation.
  3. Duty to Inform Prior to and During the Session: The Client is obliged to inform the Coach unprompted before the start of each session about any existing physical or mental limitations, acute pain, or health changes. If unusual or painful physical sensations, dizziness, or discomfort occur during the session, the Client must inform the Coach immediately.
  4. Full Self-Determination & Right to Discontinue: The Client retains full control throughout the session. The Client is entitled and encouraged at any time to independently adjust, pause, or discontinue the session without providing reasons (whether breathwork, yoga, or other formats). The practices are offered as an invitation to self-awareness.
  5. Supplementary Scope: In addition to these Terms, the Privacy Policy and the Important Health Disclaimer on the website at vayumedicina.com/gesundheitshinweis shall apply.

§ 6 Cancellation, Rescheduling & No-Show

  1. Cancellation by Client (1:1 Sessions): Free cancellation or rescheduling of agreed 1:1 individual sessions is possible up to 24 hours prior to the scheduled appointment in text form (e.g., via email).
  2. Late Cancellation & No-Show: If a cancellation occurs less than 24 hours before the appointment or if the Client fails to appear (no-show), 100% of the agreed fee will be charged as a cancellation fee. For multi-session packages, the respective session is forfeited without compensation.
  3. Cancellation of B2C Group Workshops by Provider (Minimum Participants): For group workshops or classes, the Provider reserves the right to cancel the event up to 7 days before the event date if the stated minimum number of participants is not reached. Any fees already paid will be fully refunded in this case. Further claims (such as cancellation fees for travel or accommodation tickets booked by the Client) are excluded.
  4. Cancellation by Coach (Illness/Force Majeure): In the event of acute illness of the Coach, organizational disruptions, or force majeure, the Provider may cancel or reschedule appointments or workshops at short notice. The Provider will promptly attempt to arrange a replacement date. If no replacement date is possible, fees paid for unperformed services will be refunded. Further claims for damages (such as travel or accommodation cancellation costs) are excluded.

§ 7 Consumer Right of Withdrawal

  1. Consumers located in the EU generally have a statutory 14-day right of withdrawal for distance contracts (online/email bookings).
  2. Premature Expiry of the Right of Withdrawal: The right of withdrawal expires prematurely if the Provider has fully performed the service at the explicit request of the Client before the end of the 14-day withdrawal period, and the Client gave their consent prior to performance.

§ 8 Copyright & Usage Rights

  1. All course materials, handouts, audio or video guides, and other contents provided by the Provider are protected by copyright.
  2. The Client receives a simple, non-transferable right of use for these materials exclusively for personal, private use.
  3. Any reproduction, distribution, commercial use, or publication (even in part) without the prior written consent of the Provider is prohibited.

§ 9 Photo & Video Recordings

Photo, video, or audio recordings during classes or workshops by the Provider will take place exclusively on the basis of a voluntary, separate, and revocable consent of the respective participants on site. There is no obligation to consent at any time.

§ 10 Limitation of Liability

  1. The Provider is unreservedly liable for damages resulting from injury to life, body, or health resulting from an intentional or negligent breach of duty, as well as for damages based on intent or gross negligence.
  2. For simple negligence, the Provider is only liable in the event of a breach of essential contractual duties (cardinal duties). In this case, liability is limited to the foreseeable, contract-typical damage.
  3. Data communication via the internet cannot be guaranteed to be error-free and/or available at all times given the current state of technology. To this extent, the Provider is not liable for the constant and uninterrupted availability of online booking systems.

§ 11 Final Provisions, Governing Law & Jurisdiction (Severability Clause)

  1. The law of the Federal Republic of Germany shall apply, excluding the UN Convention on Contracts for the International Sale of Goods (CISG). For consumers, this choice of law applies only to the extent that the protection granted by mandatory provisions of the law of the state in which the consumer has their habitual residence is not withdrawn.
  2. If the Client is a merchant, a legal entity under public law, or a special fund under public law, the exclusive place of jurisdiction for all disputes arising from this contract shall be the Provider’s place of business (Lemgo, Germany).
  3. Severability Clause: Should individual provisions of these Terms be or become invalid in whole or in part, the validity of the remaining provisions shall remain unaffected.
