1.1.These General Terms and Conditions (the "Terms") govern all agreements between Indo Cooperation UG, operating under the brand Volute Studio, represented by its Managing Director Mr. Doğuş Ünsalan, Rolandstr. 2-3, 30161 Hannover, Germany, e-mail: contact@volute.studio (the "Contractor" or "Volute Studio") and the client (the "Client").
1.2.The subject matter of these Terms is the provision of work services in the field of photorealistic architectural visualization, including still and moving-image deliverables (renderings, walkthrough videos) for built or planned real-estate projects (the "Work").
1.3.Volute Studio contracts exclusively with businesses (Unternehmer) within the meaning of Section 14 of the German Civil Code (BGB), legal persons under public law, and special public-law funds. Volute Studio does not enter into agreements with consumers within the meaning of Section 13 BGB.
1.4.Any conflicting, supplementary, or deviating terms of the Client shall not apply unless the Contractor has expressly agreed to them in writing. This requirement of express written consent applies in all cases, including where the Contractor renders performance without reservation despite being aware of the Client's terms.
2.1.The presentation of services on volute.studio, in brochures, quotations, and other media does not constitute a legally binding offer but an invitation to make an offer (invitatio ad offerendum).
2.2.A contract is concluded as soon as:
2.3.Alternatively or in addition, a contract is deemed concluded if, following the Client's express request, the Contractor commences performance. In this case, the commencement of work replaces a separate written confirmation.
2.4.Any side agreements require confirmation in text form by the Contractor to become effective.
3.1.The Contractor primarily provides its Work in the form of productized packages, the specific scope of which is set out in the individual quotation:
3.2.All prices are net, exclusive of statutory value-added tax (VAT). For services rendered to businesses established in another EU Member State, the reverse-charge mechanism (Section 13b German VAT Act, UStG) applies. For services rendered to businesses established outside the EU, the service is deemed non-taxable in Germany pursuant to Section 3a(2) UStG.
3.3.Services beyond the agreed scope (e.g. additional renderings, further revision rounds, structural modifications to the model, rush surcharges) are quoted separately and, upon acceptance, invoiced separately.
3.4.The Contractor reserves the right to adjust individual packages in content, price, or scope. The version of the package in force at the time the contract is concluded shall apply.
4.1.The Client shall cooperate in the proper performance of the services, in particular by providing all required documents and information in a timely manner, including:
4.2.The Client warrants that it holds all rights necessary for the contractual use of the materials provided and that no third-party rights conflict with such use. The Client shall indemnify the Contractor against any third-party claims arising from a breach of this warranty.
4.3.Delays caused by missing or late cooperation on the part of the Client extend the agreed delivery deadlines accordingly.
5.1.Unless otherwise agreed, the following indicative turnaround times apply, calculated from the receipt of all documents required under Section 4:
5.2.Turnaround times are measured against the Contractor's time zone (Central Indonesia Time, CIT, UTC+8). Business days are Monday through Friday, excluding public holidays observed in Indonesia and Bali.
5.3.Delivery dates are non-binding unless explicitly designated as binding ("fixed date") in the individual contract. In the event of force majeure (Section 14) or delays attributable to the Client under 4.3, deadlines shall be reasonably extended.
6.1.Each Hero Set and Launch Package includes two (2) revision rounds. A revision round covers adjustments to:
6.2.Structural changes — in particular moving walls, altering the roofline, adding storeys, or fundamental changes to the 3D model — are not part of the included revisions and will be quoted and invoiced separately.
6.3.Revisions beyond the contractually agreed rounds are quoted on an hourly or fixed-fee basis. The applicable hourly rate is set out in the individual quotation.
7.1.The Client shall promptly inspect the Work delivered as completed by the Contractor and shall accept it within seven (7) calendar days, provided that it conforms to the contractual specifications.
7.2.If the Client neither declares acceptance nor raises defects in text form within that period, the Work shall be deemed accepted.
7.3.Acceptance may not be refused on account of immaterial defects. Immaterial defects will be remedied under the warranty provisions.
7.4.Upon acceptance, the risk passes to the Client.
8.1.All prices are stated in Euro (EUR) net, plus any statutory VAT. The website may display prices in US dollars (US$) for reference; the legally binding invoice currency is EUR. Conversion is made on the date the contract is concluded at the reference rate published by the European Central Bank.
8.2.Unless otherwise agreed in the individual contract, the fee falls due as follows:
8.3.Development Partner programs are subject to individually negotiated payment terms set out in the annual contract (e.g. quarterly or per project milestone).
8.4.If the Client falls into default with a payment, the Contractor is entitled to charge default interest at the statutory rate (Section 288 BGB) from the day following the onset of default. The right to claim further damages remains reserved.
8.5.The Contractor is entitled to withhold delivery of the final Work and the transfer of usage rights under Section 11 until full payment has been received.
8.6.The Client may exercise rights of set-off or retention only to the extent that its counterclaims have been finally adjudicated, are undisputed, or have been acknowledged by the Contractor.
9.1.The Client may terminate the contract at any time in text form. Upon termination, the Client owes:
9.2.Advance payments already made are credited against the amount owed under 9.1. If the advance exceeds that amount, the surplus is refunded within fourteen (14) days.

10.4.The statutory warranty period is twelve (12) months from acceptance.
11.1.Upon full payment of the agreed fee, the Contractor grants the Client an unrestricted, non-exclusive, transferable and sub-licensable right of use to the final Work, unrestricted in time, territory, or content. This includes in particular:
11.2.Previews, work-in-progress files, and raw renderings supplied during the engagement may only be used publicly after full payment and acceptance.
11.3.Copyright in the underlying 3D model, proprietary pipeline components, raw data, internal working files, and preliminary studies remains with the Contractor.
11.4.Any transfer of exclusive usage rights requires a separate written agreement and a separate fee.
12.1.The Contractor is entitled to use the Work created under the contract — including with attribution of the Client's name and the project — for its own promotional purposes, in particular for the portfolio on its website, on social media, in sales collateral, and for publications in trade media.
12.2.The Client may object to such use under 12.1 at any time, informally and in text form, by writing to contact@volute.studio. Publications already made remain unaffected.
12.3.Upon the Client's express request — in particular for confidential projects under an NDA — portfolio publication will be withheld until an agreed date (e.g. public launch).
13.1.The parties shall treat as confidential all confidential information of the other party that comes to their knowledge in the course of the engagement, and shall not disclose such information to third parties.
13.2.The Contractor may engage external staff or subcontractors who are bound by comparable confidentiality obligations.
13.3.Upon the Client's request, the Contractor will enter into a separate non-disclosure agreement (NDA) before plans are exchanged. Templates are available on request; client-supplied NDAs are reviewed.
14.1.The Contractor is not liable for delays or non-performance caused by events of force majeure. These include in particular natural disasters, war, strikes, governmental orders, pandemics, prolonged power or internet outages, and other unforeseeable and unavoidable events.
14.2.In such cases, delivery deadlines are extended by the duration of the impediment plus a reasonable ramp-up period. If the impediment lasts longer than eight (8) weeks, either party may withdraw from the affected order; in that case, services already rendered are compensated pro rata.
15.1.The Contractor is liable without limitation for intent and gross negligence, as well as for damage resulting from injury to life, body, or health. Liability under the German Product Liability Act remains unaffected.
15.2.In the case of slight negligence in breach of essential contractual duties (cardinal duties), the Contractor's liability is limited to the foreseeable damage typical for this type of contract. Cardinal duties are obligations whose fulfilment is essential to the proper performance of the contract and on whose observance the Client may regularly rely.
15.3.In all other respects, liability for slight negligence is excluded.
15.4.Liability for indirect damage, lost profits, missed sales, and similar consequential losses is excluded except in cases of intent or gross negligence.
15.5.The Contractor's liability is capped at twice (2×) the value of the affected individual order.
15.6.The Contractor is not liable for the accuracy of plans, materials, and specifications provided by the Client, nor for the trademark, competition-law, or copyright admissibility of content supplied by the Client (logos, brand names, reference imagery).
Personal data is processed in accordance with applicable law (in particular the GDPR and the German Federal Data Protection Act, BDSG). Details are set out in the privacy policy at volute.studio/datenschutz.
17.1.The Contractor is entitled to amend these Terms with effect for future contracts. Ongoing contracts remain governed by the Terms in force at the time of conclusion.
17.2.Amendments will be notified to the Client at least six (6) weeks before they take effect, in text form. If the Client does not object in text form within four (4) weeks of receipt, the amendments are deemed accepted for future contracts. The Contractor will draw attention to this consequence in the notification.
18.1.These Terms are governed by the laws of the Federal Republic of Germany, excluding the UN Convention on Contracts for the International Sale of Goods (CISG).
18.2.The exclusive place of jurisdiction for all disputes arising from or in connection with contracts subject to these Terms is — to the extent the Client is a merchant, a legal person under public law, or a special public-law fund — the Contractor's registered office (Hannover, Germany). The Contractor is also entitled to sue the Client at the Client's general place of jurisdiction.
18.3.The contract language is German. All contracts, notices, and other legally binding documents are issued in German. A translation into another language (such as English) is provided for information purposes only; in case of any inconsistency or dispute over interpretation, the German version prevails.
18.4.Amendments and supplements to the contract, as well as side agreements, require text form. This applies likewise to any waiver of this text-form requirement.
18.5.Should any individual provision of these Terms be or become invalid or unenforceable, in whole or in part, the validity of the remaining provisions shall not be affected. The invalid or unenforceable provision shall be replaced by a valid and enforceable provision that comes closest to the parties' economic intent.
