Terms of Service
General Terms and Conditions (AGB). Last updated: September 4, 2026.
1. Provider and Scope
These Terms govern the use of the CALLA REF platform at app.callaref.com (the "Service"), operated by Calla Ref GmbH, Gumpendorfer Straße 63F, 1060 Vienna, Austria (the "Provider", "we"). Full company details are set out in our Imprint. They apply to all subscriptions concluded via the Service, both consumer (B2C) and business (B2B) contracts. Deviating terms of the customer do not apply unless we expressly agree in writing.
2. The Service
The Service provides on-demand access to a curated library of Reformer Pilates video sessions and related progress-tracking features, streamed over the internet. We continuously develop the Service; the specific content available may change over time. The Service requires a compatible device and a sufficient internet connection, which the customer provides at their own expense.
Some sessions are additionally available with AI-generated dubbed audio in other languages (currently German, French and Spanish) — an AI-translated, voice-cloned narration of the original English recording, not a live recording of the coach speaking that language. When an AI-dubbed audio track is active, the video player displays a visible label identifying it as such.
3. Conclusion of Contract
By completing registration and the checkout process and selecting a paid plan, the customer makes a binding offer to conclude a subscription contract. The contract is concluded when the checkout process is successfully completed, at which point access to paid content begins immediately. For contracts concluded in this way, we confirm the concluded contract to you by e-mail once checkout has completed. Some signups include a free trial period before the first charge; whether a trial applies, and its length, is shown during registration and checkout.
Where a subscription is not concluded through the checkout process — in particular business subscriptions agreed with us separately, and access we provide for evaluation or demonstration purposes — the contract is concluded on the terms separately agreed with you and at the time those terms provide for, and, where access is provided for evaluation or demonstration only, when we grant that access. No checkout confirmation e-mail is sent in either case. Your statutory rights as a consumer, including those set out in section 6, are not affected by this.
4. Prices and Payment
Prices are shown during checkout. For consumers (B2C), prices are stated including statutory Austrian VAT (currently 20%). For business customers (B2B), VAT is handled according to the applicable tax rules (including the reverse-charge mechanism for valid EU VAT IDs); the price and tax shown at checkout are decisive.
Payment is processed by our payment service provider, Stripe. An invoice meeting the requirements of § 11 Austrian VAT Act is issued for each payment. Subscription fees are charged in advance for the chosen billing period (monthly or annual) and recur automatically until cancelled.
5. Term, Renewal and Cancellation
The subscription runs for the selected billing period and renews automatically for further periods of the same length unless cancelled before the end of the current period. Customers can cancel at any time with effect from the end of the current paid period via the customer portal (self-service plan management, cancellation, payment-method and invoice access) or by written notice to contact@callaref.com. The written channel also applies to business and partner accounts billed outside the customer portal. B2B plan changes are handled on request. Cancellation does not entitle the customer to a refund of fees already paid for the current period, except where mandatory law (including § 11 FAGG) or Section 6 below provides otherwise.
6. Right of Withdrawal for Consumers (FAGG)
The following applies to consumers within the meaning of the Austrian Consumer Protection Act. Business customers (B2B) have no statutory right of withdrawal.
Withdrawal Instructions
You have the right to withdraw from this contract within 14 days without giving any reason. The withdrawal period is 14 days from the day of the conclusion of the contract. To exercise the right of withdrawal, you must inform us (Calla Ref GmbH, Gumpendorfer Straße 63F, 1060 Vienna, Austria, contact@callaref.com) of your decision to withdraw by an unequivocal statement (e.g. a letter sent by post or e-mail). You may use the model withdrawal form below, but it is not obligatory. To meet the withdrawal deadline, it is sufficient to send your communication concerning the exercise of the right of withdrawal before the withdrawal period has expired.
Effects of withdrawal: If you withdraw from this contract, we will reimburse all payments received from you without undue delay and no later than 14 days from the day on which we are informed of your decision to withdraw, using the same means of payment you used for the original transaction, unless expressly agreed otherwise.
Please note: for digital content supplied before the withdrawal period has expired, this right can lapse early. Where you have given the express consent and acknowledgement described immediately below, the 14-day right of withdrawal — and with it the reimbursement set out above — no longer applies.
Early loss of the right of withdrawal (digital content)
The Service supplies digital content not on a tangible medium, and providing access immediately — before the 14-day withdrawal period has expired — is how the Service is delivered. In accordance with § 18 para. 1 no. 11 FAGG, this early loss of the right of withdrawal requires (a) your express consent to us beginning performance before the withdrawal period has expired, and (b) your acknowledgement that you thereby lose your right of withdrawal. You give both before your subscription is activated — when you register, or, if your account reached us without them, when you start your subscription — and we confirm your consent to you on a durable medium (by e-mail). We cannot start a consumer subscription without this consent and acknowledgement, because immediate access is integral to how the Service is provided.
Cancellation form
(Complete and return this form only if you wish to withdraw from the contract. This is the statutory model withdrawal form under the FAGG.)

— Date: __________
7. Permitted Use and Licence
We grant the customer a non-exclusive, non-transferable right to access and view the content for personal use for the duration of the subscription. B2B subscriptions additionally permit use on the agreed number of devices in the customer's premises (e.g. studio, gym, hotel). The customer may not download (except as offered by the Service), copy, redistribute, publicly perform, sublicense, or commercially exploit the content, nor circumvent access controls or share account credentials.
8. Intellectual Property
All content, trademarks, and software of the Service are protected by copyright and other intellectual-property rights and remain the property of Calla Ref GmbH or its licensors. No rights are granted beyond those expressly set out in these Terms.
9. Health and Fitness Disclaimer
The content provided through the Service — including all Reformer Pilates videos, instructions, and recommendations — is for general informational and educational purposes only. It is not a substitute for professional medical advice, diagnosis, or treatment.
You acknowledge and agree that you exercise entirely at your own risk. Calla Ref GmbH, its instructors, employees, partners, and affiliates shall not be liable for any injury, health issue, physical damage, or loss arising from or in connection with your use of the Service, including but not limited to injuries sustained during or as a result of following any workout content, except within the limits of Section 10.
Before beginning any exercise programme, you should consult a qualified healthcare professional, particularly if you have pre-existing health conditions, injuries, or are pregnant. You are solely responsible for ensuring that the exercises are appropriate for your individual fitness level and physical condition. By using the Service, you confirm that you are not pregnant; Reformer Pilates exercises may pose risks during pregnancy, and the Service is not designed for use by pregnant individuals.
10. Liability
We are liable without limitation for damages caused by intent or gross negligence and for injury to life, body or health, as well as under the mandatory Austrian Product Liability Act. For slightly negligent breaches we are liable only for the breach of essential contractual obligations and limited to the foreseeable, contract- typical damage. Any further liability is excluded. Mandatory statutory consumer rights remain unaffected.
11. Availability
We endeavour to keep the Service available but do not warrant uninterrupted or error-free operation. Maintenance, technical issues, or third-party-provider outages may cause temporary unavailability. This does not affect mandatory warranty rights.
12. Data Protection
We process personal data in accordance with our Privacy Policy, which forms part of the information provided to you.
13. Changes to These Terms
We may amend these Terms for valid reasons (e.g. changes in the law or in the Service). We will notify customers of material changes by e-mail at least 30 days before they take effect, separately highlighting the change. For changes that do not disadvantage the consumer or are only minor, the changes are deemed accepted if the consumer does not object before they take effect; we will point this out in the notification, and the consumer may terminate the contract free of charge before they take effect. Changes to the price or to the essential scope of the Service are not subject to this deemed-acceptance mechanism: they apply only from the next renewal period, are notified in advance, and the customer may cancel before the new period begins if they do not agree.
14. Governing Law and Jurisdiction
Austrian law applies, excluding the UN Convention on Contracts for the International Sale of Goods and conflict-of-law rules. For consumers, this choice of law does not deprive the consumer of the protection of mandatory provisions of the law of their country of habitual residence. For contracts with entrepreneurs, the exclusive place of jurisdiction is Vienna, Austria.
15. Dispute Resolution
The European Commission provides an online dispute resolution (ODR) platform: https://ec.europa.eu/consumers/odr. We are neither obligated nor willing to participate in dispute resolution proceedings before a consumer arbitration board.
