Terms and Conditions and Terms of Use for LUMACUE

This is an English translation for your convenience. The German version prevails.

1. Provider, scope, definitions

1.1 The provider of the LUMACUE software (macOS app for controlling lighting from DJ data), the website https://lumacue.sijofx.io, the user account and the licence server is SiJoFX – Stöckl & Sannmann GbR, represented by its partners Simon Stöckl and Joshua Sannmann, Schierblicken 17, 23843 Bad Oldesloe, Germany, e-mail simon@sijofx.io ("we" or "SiJoFX").

1.2 These terms govern the use of the website, the account, the software in the tiers Free, Trial and Pro (including Founder), and the licence agreement between you and us. They apply to consumers (Section 13 BGB) and businesses (Section 14 BGB). Deviating terms of the user do not become part of the contract.

1.3 "Billing period" means the period paid for (one month or twelve months). "Customer portal" means the portal provided by Lemon Squeezy for managing your order.

2. Two contractual levels: Lemon Squeezy as seller, SiJoFX as software provider

2.1 LUMACUE Pro is purchased through our distribution partner Lemon Squeezy, LLC, 1 Market Street, Suite 400, San Francisco, CA 94105, USA (part of Stripe, Inc.; "Lemon Squeezy"). Lemon Squeezy acts as seller and reseller (merchant of record). This means:

1. The purchase contract for the subscription (obligation to pay, term, renewal) is concluded between you and Lemon Squeezy. Lemon Squeezy issues the invoice, collects and remits applicable taxes, collects payments and processes refunds.
2. Lemon Squeezy's buyer terms apply in addition to payment, invoicing, refunds and management of the subscription in the customer portal. Where those terms conflict with mandatory German consumer protection law or fall short of the statements in these Terms, our withdrawal notice or the information at the order buttons, our statements and mandatory law prevail for consumers resident in Germany.
3. The licence agreement for the software (scope of licence, account, licence server, updates, support) exists between you and us. We are your contact for all questions regarding the software, the account and the licence.

2.2 After purchase, Lemon Squeezy transmits to us the order and subscription status, your e-mail address and your account identifier so that we can activate the licence (see Privacy Policy).

2.3 The Free tier and the trial are agreed directly with us without involvement of Lemon Squeezy (section 5).

3. Scope of services

3.1 LUMACUE Free (EUR 0): simulation, reading PRO DJ LINK with up to 2 decks, drop countdown, kick-roll notes, monitor view on 1 device, analysis of your own files (max. 20 tracks). Not included: timecode, grandMA and OSC output, Serato input. The monitor view shows a "LUMACUE Free" overlay.

3.2 LUMACUE Pro: all features, in particular 4 decks, Serato input, timecode (LTC/MTC/Art-Net), grandMA2/3 commands, automation and node editor, unlimited library, monitor on any number of devices, activation on up to 2 computers.

3.3 LUMACUE Pro Founder: same scope as Pro at the Founder price (section 6.2).

3.4 Trial: 30 days of LUMACUE Pro free of charge, without payment details, via an account. After expiry the account switches automatically to Free. No subscription and no obligation to pay arises. The trial may be used once per person.

3.5 System requirements, compatibility and interoperability: LUMACUE runs on macOS. The software reads and sends third-party protocols and formats (PRO DJ LINK, rekordbox, Serato, LTC/MTC, Art-Net, grandMA commands, OSC, Resolume). These protocols are defined by third parties and may change; we do not warrant that third-party devices or software will work together in every version and configuration. These product names are used descriptively only; we are not affiliated with or certified by the trademark owners.

3.6 Operation without cloud: LUMACUE works locally on your computer. The app connects to our licence server only for activation, periodic renewal and deactivation of the licence (section 8). No usage data or telemetry is transmitted.

4. Account

4.1 Free, Trial and Pro require an account with e-mail address and password. After registration you receive an e-mail with a confirmation link (double opt-in). The account becomes active only upon confirmation.

4.2 You must be of legal age and have full legal capacity. Your details must be accurate; notify us of changes to your e-mail address via the account.

4.3 Keep your password secret. Inform us without delay if you suspect misuse of your account. An account is personal and may not be passed on to third parties.

4.4 In the account you can view your licences and activated computers, deactivate computers, export your data as JSON and delete the account (section 13).

5. Conclusion of contract

5.1 Free and Trial: the licence agreement is concluded when you submit the registration form and confirm your e-mail address via the confirmation link. The trial begins when you select "Start free trial" in the account or during registration.

5.2 Pro (subscription): on the pricing page you choose a variant (monthly, yearly, Founder). Clicking "Order with obligation to pay" takes you to the Lemon Squeezy checkout. Before placing the order you can review and correct your entries. By completing the order at checkout you make a binding offer; the purchase contract with Lemon Squeezy is concluded upon Lemon Squeezy's order confirmation. The licence agreement with us for LUMACUE Pro is concluded as soon as we activate the licence in your account; you then receive a confirmation e-mail from us with these Terms, the withdrawal notice and the essential contract data (Section 312f BGB).

5.3 The contract language is German. An English version is provided for information; in case of discrepancies the German version prevails. You can access, save and print the Terms at https://lumacue.sijofx.io/agb; we do not store the contract text in your account; the confirmation e-mail contains the contract data.

6. Prices and payment

6.1 LUMACUE Pro costs EUR 9.99 per month or EUR 89 per year.

6.2 LUMACUE Pro Founder costs EUR 6.99 per month or EUR 59 per year. The Founder price can be taken out up to and including 31 December 2026. It applies as long as your Founder subscription runs without interruption. If the subscription ends (cancellation, non-payment, withdrawal) or you change the variant, the Founder price lapses; a later subscription is at the regular price then applicable.

6.3 All prices are total prices in euros. In accordance with Section 19 UStG, SiJoFX does not charge VAT. The seller is Lemon Squeezy; Lemon Squeezy issues the invoice.

6.4 Payment is made in advance for the respective billing period using the payment methods offered at the Lemon Squeezy checkout. Lemon Squeezy collects payment at the start of each billing period.

6.5 Price changes for running subscriptions do not apply to the billing period already paid. For subsequent periods they apply only if we inform you by e-mail at least four weeks before they take effect and you do not cancel the subscription before that date; we will point out the right to cancel in the notice. Founder subscriptions are exempt from price increases as long as they run without interruption.

7. Term, renewal, cancellation

7.1 The monthly subscription has a term of one month, the yearly subscription twelve months. It renews automatically for the same duration unless cancelled with effect from the end of the current billing period.

7.2 You may cancel the subscription at any time without notice period with effect from the end of the current billing period. Cancellation is possible via the button "Cancel contracts here" and the confirmation page https://lumacue.sijofx.io/kuendigen (no login), in the Lemon Squeezy customer portal, or by e-mail to simon@sijofx.io. We confirm receipt of the cancellation without delay by e-mail stating date, time and termination date (Section 312k BGB). A cancellation declared to us is forwarded to Lemon Squeezy.

7.3 LUMACUE Pro remains fully available until the end of the billing period. The account then switches automatically to Free. Projects and settings remain locally on your computer; Pro features are no longer available.

7.4 No pro-rata refund is made for the unused remainder of the term in the case of ordinary cancellation. Your statutory right of withdrawal (section 12) and your statutory rights in case of defects (section 10) remain unaffected.

7.5 The right of either party to terminate for good cause remains unaffected. Good cause exists for us in particular if you seriously or repeatedly breach the licence terms (section 8).

7.6 Free and Trial: you may end the licence agreement at any time by deleting the account. We may terminate Free access with four weeks' notice by e-mail; paid subscriptions are not affected.

8. Licence and licensing technology

8.1 For the duration of the licence agreement we grant you the simple, non-exclusive, non-transferable and non-sublicensable right to install and use LUMACUE in the licensed tier on the permitted number of computers. Private and professional use is permitted.

8.2 Pro and Trial may be activated on no more than 2 computers at the same time. You can deactivate computers in the account and activate another computer.

8.3 Technology: the licence is issued as an Ed25519-signed licence file. On activation the app transmits to our licence server your licence key, a device identifier formed from device characteristics (hash), the app version and the time. The licence file is stored locally; the app also runs offline with it. The licence is renewed periodically; after the end of the billing period a grace period of 7 days applies during which the app continues to run until the licence is renewed or reset to Free.

8.4 Not permitted: passing on, renting or selling the licence or account; circumventing the licence check; removing protection mechanisms or notices; decompiling or modifying the software except as mandatorily permitted under Sections 69d, 69e UrhG (German Copyright Act); using the software for unlawful purposes.

8.5 LUMACUE contains open-source components. These are governed by their respective open-source licences, listed in the app (About dialog) and at https://lumacue.sijofx.io/licenses; these Terms do not restrict them.

8.6 LUMACUE controls lighting and show equipment. It is not a safety system and is not intended for purposes where a failure could endanger people (e.g. emergency or safety lighting, pyrotechnics, moving loads). You are responsible for the safe setup of your event technology and for compliance with the regulations applicable there.

9. Updates and modifications (Sections 327f, 327r BGB)

9.1 During the term of a Pro subscription we provide the updates required to keep the software in conformity with the contract, including security updates, and inform you of them in the app or by e-mail. If you fail to install a provided update within a reasonable period, we are not liable for defects resulting solely from this, provided we informed you of the availability and the consequences and the installation instructions were correct.

9.2 For Free we provide updates at our discretion; there is no entitlement to feature enhancements.

9.3 We may modify the software beyond what is required to maintain conformity (e.g. new features, adaptation to new macOS versions, changed third-party protocols, security requirements, simplified operation) provided this causes you no additional cost and we inform you clearly and comprehensibly. If a modification impairs your access or usability more than insignificantly, we will inform you in advance by e-mail; you may then end the contract free of charge within 30 days unless you can continue to use the unmodified software without additional cost (Section 327r BGB).

10. Warranty

10.1 Consumers have the statutory rights in case of defects in digital products (Sections 327 et seq. BGB), in particular to subsequent performance, termination or price reduction, and damages (Section 327i BGB). These rights are directed against us as provider of the software; for the payment processing of a refund we use Lemon Squeezy.

10.2 For businesses the limitation period for claims for defects is one year from provision; this does not apply to claims for damages under section 11.

10.3 For Free, insofar as no price and no counter-performance in the form of personal data beyond what is required to perform the contract is owed, warranty exists only under the general provisions. Our liability under section 11 remains unaffected.

10.4 The licence server is required for activation, renewal and deactivation; otherwise the app works offline. We strive for high availability of the licence server but cannot exclude short interruptions for maintenance or due to disruptions beyond our control. The grace period under section 8.3 bridges such interruptions.

11. Liability

11.1 We are liable without limitation for damage resulting from injury to life, body or health, for intent and gross negligence, under the German Product Liability Act, and to the extent of a guarantee we have given.

11.2 In the event of slightly negligent breach of a material contractual obligation (an obligation whose fulfilment is essential to the proper performance of the contract and on whose observance you may regularly rely), our liability is limited to the typical damage foreseeable at the time of conclusion of the contract. Otherwise liability for slight negligence is excluded.

11.3 The limitations also apply to the personal liability of our partners, employees and agents.

11.4 For loss of data we are liable within the scope of 11.1 and 11.2 only to the extent that would have occurred even with regular backups appropriate to the risk on your part.

11.5 Third-party protocols and devices (section 3.5) are beyond our control. We give no warranty for their behaviour; our liability under 11.1 and 11.2 remains unaffected.

12. Right of withdrawal for consumers

Consumers have a statutory right of withdrawal when taking out a Pro subscription. Details, the model withdrawal form and the notes on early commencement of the service are set out in the withdrawal notice at https://lumacue.sijofx.io/widerruf. You may declare the withdrawal to Lemon Squeezy as seller or to us; a withdrawal received by us is forwarded to Lemon Squeezy without delay.

13. Account deletion, data export, use after the end of the contract

13.1 You can delete your account at any time in the account. Deletion ends all licences; activated computers fall back to Free or lose the Pro licence when the local licence file expires. A running subscription must be cancelled separately (section 7.2), otherwise it would continue to be charged; we will point this out before deletion.

13.2 Before deletion you can export your account data (licences, devices, cancellation records) as JSON. Content you create (projects, analyses, settings) is stored exclusively locally on your computer; we do not store it (Section 327p BGB).

13.3 After the end of the contract you may not continue to use LUMACUE Pro; use of Free remains possible as long as an account exists.

14. Changes to these Terms

We may amend these Terms for the future where necessary due to changes in law, case law, our range of services or technical circumstances, provided the change does not unreasonably disadvantage you. We will notify you of changes by e-mail at least four weeks before they take effect. If you do not object before they take effect, the amended Terms apply; we will point out this consequence and your right to object in the notice. If you object, either party may terminate the contract with effect from the end of the current billing period. Price changes are governed by section 6.5, software modifications by section 9.

15. Dispute resolution, applicable law, jurisdiction

15.1 We are neither willing nor obliged to participate in dispute resolution proceedings before a consumer arbitration board (Section 36 VSBG).

15.2 The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods. For consumers this choice of law applies only insofar as it does not deprive you of the protection of mandatory provisions of the state in which you have your habitual residence.

15.3 If you are a business, 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 is our registered office in Bad Oldesloe. For consumers the statutory places of jurisdiction apply.

15.4 Should individual provisions of these Terms be invalid, the validity of the remaining provisions remains unaffected.

Stand: 10.11.2026, Version 1.0 Changelog: 1.0 (10.11.2026) – initial version. The German version prevails.
