Terms and conditions of sale
1. Purpose
These conditions govern the sale, through appia.works, of licences to use the APPIA software, whose owner and licensor is Thaum Creative Media S.L. (CIF B05777842, calle Urgel, 27, local, 28019 Madrid, Spain), to consumers and users. Purchasing a licence implies acceptance of these conditions, the Legal Notice, the Privacy Policy and the Software Licence Agreement.
2. Product and price
APPIA is sold as a one-off, perpetual licence (no recurring fee): you pay once and the licence does not expire. The price in force at any time is the one published on the Site at the moment of purchase, stated in euros and indicating whether or not it includes applicable taxes.
Thaum Creative Media S.L. may change the price at any time; the change will not affect licences already purchased.
3. Purchase, payment and delivery
The purchase is made through Polar (polar.sh), the payment platform integrated into the Site, which handles payment, applicable taxes and the invoice. Once payment is confirmed, the licence key and the software download link are delivered immediately, normally by email to the address provided during the purchase. The key is entered in the application itself to activate it on each device.
The invoice is issued through Polar with the tax details the buyer provides when paying (for example, a company tax ID if buying on behalf of a company or school).
4. Scope of the licence purchased
Each licence purchased authorises the installation and use of APPIA on up to 2 (two) personal-use devices of the same buyer, under the terms detailed in the Software Licence Agreement (EULA), which forms an integral part of these conditions.
5. Right of withdrawal
In accordance with Article 103.m) of the consolidated text of the Spanish General Law for the Protection of Consumers and Users (Royal Legislative Decree 1/2007), the right of withdrawal does not apply to the supply of digital content not provided on a tangible medium when performance has begun with the prior express consent of the consumer, who acknowledges that they thereby lose their right of withdrawal. By confirming the purchase, the buyer expressly accepts the immediate start of the download and, with it, the loss of this legal right.
Notwithstanding the above, and as an additional voluntary commercial guarantee (not required by law), Thaum Creative Media S.L. offers a full refund if requested within 14 calendar days of the purchase. The request is handled through Polar, the platform used for payment. When the amount is refunded, the licence key is cancelled and the application switches to read-only mode on all devices (plays can still be opened and exported). After that period, no refunds will be made except as provided by the legal guarantee for product defects.
6. Guarantees and support
Thaum Creative Media S.L. provides reasonable technical support on the operation of APPIA through support@appia.works. The legal guarantees applicable to consumers, and the limitations of liability regarding the software itself, are detailed in the Software Licence Agreement.
7. Applicable law and dispute resolution
These conditions are governed by Spanish law. Consumers resident in the European Union may use the European Commission's online dispute resolution platform (ec.europa.eu/consumers/odr) for the out-of-court resolution of disputes. Without prejudice to this, and in accordance with consumer law, the court of the consumer's place of residence shall have jurisdiction.
Software licence agreement (EULA)
1. Parties and acceptance
This end-user licence agreement ("EULA") is entered into between Thaum Creative Media S.L. (CIF B05777842), as licensor, and the person who purchases an APPIA licence ("the licensee"). Installing or using the software implies full acceptance of this EULA.
2. Grant of licence
Thaum Creative Media S.L. grants the licensee, for as long as they comply with these conditions, a personal, non-exclusive and non-transferable licence to use APPIA, in exchange for the corresponding one-off payment. The licence is perpetual: it does not expire or require renewal.
The licence authorises the installation and use of the software on up to 2 (two) personal-use devices of the same licensee at the same time. Sharing, assigning, renting, sublicensing or reselling the licence to a third party is not permitted without express written authorisation.
Each device is activated by entering the licence key in the application, which requires an internet connection at that moment; a device can be released from the application itself or from Polar's customer portal in order to activate another one. The application periodically checks that the licence is valid and works offline for up to 30 days since the last successful check. Without a valid licence on the device — because it has not been activated, has been cancelled after a refund or could not be checked within that period — APPIA works in read-only mode: plays can be opened and exported, but not edited, created or imported. Plays are never locked or deleted.
3. Restrictions
Unless the applicable law expressly and mandatorily provides otherwise, it is not permitted to: (a) reverse engineer, decompile or disassemble the software; (b) modify, adapt or create derivative works from APPIA; (c) remove or alter the intellectual property notices in the software; (d) distribute, publish or make available to third parties the software or any copy of it beyond what is expressly permitted in this document.
4. Intellectual property
APPIA, its source code, its design and its documentation are the property of Thaum Creative Media S.L. and are protected by intellectual property law. This EULA grants only a right of use; it does not transfer any ownership of the software. The plays and other content the user writes with APPIA are their exclusive property: Thaum Creative Media S.L. claims no rights over them and never has access to them, since they are stored only on the user's computer and the software never sends them to any server.
5. Updates
The licence includes, at no extra cost, the updates and fixes published within the same major version of the software purchased at the time of purchase. Versions 0.x are part of version 1: anyone who purchases a 0.x version also receives all 1.x versions at no cost. Moving to a future major version may be sold, where applicable, as a separate paid upgrade, which will be announced with reasonable notice.
6. Warranty and limitation of liability
APPIA is provided "as is", without warranties of any kind beyond those that cannot legally be waived for consumers under applicable Spanish and European law. To the maximum extent permitted by law, Thaum Creative Media S.L. shall not be liable for indirect damages, data loss or loss of profit arising from the use of the software, while strongly recommending that users make regular backups of their own work — APPIA includes its own automatic backup and versioning system for this purpose, described in its documentation.
7. Term and termination
This EULA is valid indefinitely as long as its conditions are met. In the event of serious breach by the licensee, the licence may be terminated, and the licensee must then stop using the software and delete all installed copies, with no right to a refund of the price paid except as provided by the commercial guarantee described in the Terms and Conditions of Sale.
8. Applicable law
This EULA is governed by Spanish law, without prejudice to the consumer protection rules that may apply by reason of the user's habitual residence within the European Union.
