1. Scope
These terms apply to the SimDeckOS software, the user account, the Content Library and the Studio of Martin Naglmayr (“SimDeckOS”, “we”; see the imprint). They apply to consumers and businesses unless stated otherwise below. Mandatory consumer rights always remain unaffected.
2. Services
- SimDeckOS (free): the software with its basic features.
- User account (free): access to the Content Library and the Studio, and signing in to the software.
- Premium and Supporter (subscription): additional features as described on the pricing page. Supporter includes Premium plus access to early builds, which may still contain bugs.
SimDeckOS requires SimHub and, depending on the device, other third-party software (e.g. the Stream Deck software). Their makers' terms apply to those; we are not affiliated with them.
3. User account
You must be at least 14 years old to hold an account. Only adults, or minors with their legal guardian's consent, may take out a subscription. Your details must be accurate and your password kept secret. An account belongs to one person and is not transferable. You can delete your account yourself at any time (see the privacy policy).
4. Licence and warranty
You receive a non-exclusive, non-transferable right to use SimDeckOS for your own purposes on your devices. Premium features are bound to your account. You may not resell or pass on the software or Premium access, circumvent licence checks, or modify the software except where the law (in particular §§ 40d and 40e of the Austrian Copyright Act) expressly permits it.
The statutory warranty applies — for consumers under the Austrian Consumer Warranty Act (VGG), including the provision of necessary updates. Features expressly marked “beta” or “early build” may still be incomplete.
5. Premium subscription
Premium and Supporter are billed monthly or yearly through Lemon Squeezy LLC acting as reseller (merchant of record); its purchase terms apply in addition. Prices include statutory VAT, which Lemon Squeezy remits. The subscription renews for the chosen term until you cancel; you can cancel at any time, effective at the end of the current period, in the customer portal. Price changes apply only from the following period and are announced at least 30 days in advance; you may cancel before then.
For your right of withdrawal as a consumer see Withdrawal & refunds.
6. User content
By publishing content in the Content Library or the Studio you confirm that you hold the necessary rights and that it infringes no third-party rights or laws. You grant us a non-exclusive, worldwide, royalty-free right to store and display it and to offer it to other users for download while it is published. Other users may use downloaded content for their own purposes.
We do not fully pre-screen content but may review, reject or remove it if it breaches these terms or the law; you will be told why and can object.
Reporting illegal content
Please send notices of illegal content (Art. 16 DSA) with a link, the reason and your contact details to support@simdeckos.com. This address is also our single point of contact for authorities and users under Art. 11 and 12 DSA (languages: German, English).
7. User obligations
Prohibited in particular: attacking our systems, automated bulk downloading from the Content Library, uploading malware, and insulting, inciting or infringing content. For serious or repeated breaches we may suspend the account after a warning; paid periods are then refunded pro rata unless the breach was intentional.
8. Availability and changes
We aim for smooth operation of the online services but cannot promise uninterrupted availability (e.g. maintenance, outages at providers). SimDeckOS is developed continuously. Changes that substantially reduce Premium features are announced in advance; you may then cancel your subscription with immediate effect and receive a refund for the unused part.
9. Liability
We are liable without limitation for intent and gross negligence and for personal injury. For slight negligence we are liable only for breach of essential contractual duties, limited to the typical, foreseeable damage. Towards consumers, liability for personal injury is never excluded (§ 6(1)(9) Austrian Consumer Protection Act). We recommend backing up your settings regularly.
10. Changes to these terms
We notify registered users of changes by email at least 30 days before they take effect. Changes to your disadvantage apply only with your consent; if you do not consent, you may cancel your subscription as of the change.
11. 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 applies only insofar as it does not deprive them of the protection of mandatory provisions of the law of their habitual residence. For consumers resident in Austria, § 14 of the Consumer Protection Act governs jurisdiction; for businesses, the competent court at our seat.
