Terms of Service
§ 1 Scope
(1) These General Terms and Conditions ("Terms") govern all contracts between Thiel, Thomas und Gerhold, Frank GbR (a German civil-law partnership), Mariendorfer Str. 7, 34127 Kassel, Germany ("Provider") and users ("User") regarding the use of the SYSLIA software under the domains syslia.de and syslia.app and in the associated applications.
(2) These Terms apply to both entrepreneurs and consumers, unless a specific provision expressly distinguishes between these groups.
(3) Deviating, conflicting or supplementary general terms and conditions of the User shall only become part of the contract if the Provider has expressly agreed to their application in text form.
§ 2 Subject matter
(1) SYSLIA is a web-based Software-as-a-Service application for digital systemic constellation work. The Provider makes the software available to the User via the internet as a web app and – where available – as a desktop application for Windows and macOS.
(2) The specific scope of services is determined by the plan subscribed to and the feature overview described on the website at the time of contract conclusion.
(3) The following plans are offered in particular: Free, Standard, Pro, Max and Enterprise.
(4) The Provider is entitled to further develop, technically adapt or modify features, provided that the contractually owed core scope of services is maintained and the change is reasonable for the User.
§ 3 Contract formation
(1) The presentation of SYSLIA on the website does not constitute a legally binding offer, but an invitation to place an order or to register.
(2) The contract for the Free plan is concluded upon completion of registration on syslia.app.
(3) For paid plans, the contract is concluded once the User completes the order or upgrade process and the purchase is confirmed at checkout.
(4) Our order process is conducted by our online reseller Paddle.com. Paddle.com Market Limited is the Merchant of Record for all our orders. Paddle provides all customer service inquiries related to payment and handles returns, invoicing and the tax processing of the purchase.
(5) Where Paddle acts as Merchant of Record, the contractual partner shown at checkout is authoritative for the payment transaction, invoicing, refunds and the calculation, collection and remittance of any applicable VAT, GST, Sales Tax or comparable levies.
§ 4 Trial period
(1) Upon first registration, the User may be granted a free trial period with extended functionality.
(2) Unless otherwise stated on the website or at checkout, the trial period is 7 days.
(3) After the trial period expires, the User is automatically downgraded to the Free plan unless a paid plan has been subscribed to.
(4) No credit card is required for the trial period unless otherwise stated in the specific offer.
§ 5 Prices, taxes and payment
(1) The prices stated on the website or in the respective offer at the time of contract conclusion apply.
(2) Prices stated on the website are base prices in EUR. As SYSLIA is sold internationally and tax treatment may vary by country and tax status of the purchaser, the total amount applicable to the User is displayed bindingly only at checkout.
(3) Paddle.com Market Limited acts as Merchant of Record and is responsible for calculating, collecting and remitting any applicable VAT, GST, Sales Tax or comparable levies.
(4) Depending on the User's place of business, location or tax status and any VAT identification number provided, taxes may be added, omitted or handled under the reverse-charge procedure at checkout, to the extent supported by Paddle.
(5) The total amount shown in the Paddle checkout immediately before completing the purchase, including all applicable taxes and levies, is authoritative.
(6) Paid subscriptions are billed monthly or annually in advance depending on the chosen plan.
(7) Payment is made via the payment methods offered by Paddle.
§ 6 Term, automatic renewal and cancellation
(1) Paid subscriptions are concluded for the term chosen by the User.
(2) Monthly subscriptions automatically renew for one further month unless cancelled before the end of the current billing period.
(3) Annual subscriptions automatically renew for a further twelve months unless cancelled before the end of the current billing period.
(4) Cancellation may be declared via the user portal, via a management link provided by Paddle, or in text form to the Provider, unless mandatory procedural requirements of the Merchant of Record model preclude this.
(5) Cancellation takes effect at the end of the current billing period.
(6) Fees already paid will not be refunded on a pro-rata basis unless mandatory statutory provisions or expressly agreed refund policies provide otherwise.
(7) The right to extraordinary termination for good cause remains unaffected.
§ 7 Right of withdrawal for consumers
(1) Consumers have a statutory right of withdrawal in distance selling contracts. Details are set out in the separate withdrawal policy on the website.
(2) For contracts for digital content or digital services, the right of withdrawal may expire early under the statutory conditions, in particular if the consumer has expressly agreed that performance of the contract begins before the expiry of the withdrawal period and has confirmed that they thereby lose their right of withdrawal.
(3) Where Paddle acts as Merchant of Record, withdrawal, unwinding and refunds may be processed in whole or in part via Paddle's designated procedures.
§ 8 Licence rights
(1) The Provider grants the User, for the duration of the contract, a simple, non-exclusive, non-transferable and non-sublicensable right to use SYSLIA within the scope of the plan subscribed to.
(2) Use is limited to the User's own professional or private purposes.
(3) Transfer, sublicensing, public making available outside the intended product functionalities, commercial resale or abusive use is prohibited.
(4) Content, boards and other data created by the User in SYSLIA remain attributed to the User. The Provider's rights in the software itself are not affected thereby.
(5) Concurrent use. Each licence entitles the User to use SYSLIA on one device at a time (one active access). If the User signs in with the same account on another device, use can be moved there; the session on the previous device is ended. Concurrent use on several devices requires additional licences under paragraph 6.
(6) Additional licences. An additional licence extends the licence of the user account by one further concurrent access each, including use by the User's employees within the User's own professional purposes. Additional licences require a paid plan and are concluded as separate add-on subscriptions billed monthly or yearly; they renew automatically and can be cancelled at the end of each billing period. The price follows the tier shown at purchase (percentage of the respective plan price) and remains unchanged for the individual add-on subscription. § 14 (2) to (4) (payment default, coupling to the main subscription, non-transferability) apply accordingly.
§ 9 User obligations, content and responsibility
(1) The User is solely responsible for content entered, created, stored, transmitted or displayed by the User in SYSLIA.
(2) The User must ensure that the use of SYSLIA and the content and constellations created with the software do not violate applicable law, third-party rights or contractual obligations towards third parties.
(3) The Provider merely provides the software. It accepts no responsibility for the professional, substantive or therapeutic use of SYSLIA by the User, in particular not for decisions, measures or outcomes that the User takes in the course of coaching, supervision, counselling or therapy processes with clients.
(4) The User indemnifies the Provider against all claims by third parties arising from unlawful use of SYSLIA by the User or from unlawful content caused by the User, to the extent that the User is responsible for the breach.
(5) The User is obliged to keep their access credentials confidential and to protect them from unauthorised access by third parties.
(6) The User may not use SYSLIA in particular for storing, processing or distributing unlawful content, disrupting or overloading the infrastructure, circumventing technical protection measures or for other abusive purposes.
(7) In the event of a culpable breach of material contractual obligations, the Provider is entitled to temporarily block access at its reasonable discretion. In the case of serious breaches, blocking may occur without prior notice.
§ 10 Availability and service changes
(1) The Provider endeavours to ensure high availability of the services but does not owe availability at all times and without interruption.
(2) Maintenance work, security updates, technical developments, capacity limits or disruptions within the sphere of influence of third parties may lead to temporary limitations.
(3) The Provider is entitled to change, adapt or further develop services where there is a factual reason to do so and the change is reasonable for the User.
§ 11 Amendments to these Terms
(1) The Provider is entitled to amend these Terms with effect for the future where there is a compelling reason, in particular in the event of changes in the legal situation, technical framework conditions, product structure or processes with Paddle as Merchant of Record.
(2) Amendments will be communicated to the User in text form or within the application in good time.
(3) Where the amendment concerns material contractual obligations, the owed core scope of services or fees to the User's detriment, the amendment shall only take effect with the User's express consent.
(4) Otherwise, the Provider may set a reasonable amendment period. The User will be specifically informed in the amendment notice of the consequences of failing to object. In this case the User has the right of extraordinary termination until the amendment enters into force.
§ 12 Liability
(1) The Provider is fully liable for damages arising from injury to life, body or health caused by a wilful or negligent breach of duty by the Provider, its legal representatives or agents.
(2) The Provider is also fully liable for damages caused by wilful misconduct or gross negligence.
(3) In the event of a slightly negligent breach of material contractual obligations, liability is limited to the foreseeable damage typical for the type of contract. Material contractual obligations are those whose fulfilment is essential for the proper performance of the contract and on whose observance the User may regularly rely.
(4) Otherwise, liability for slight negligence is excluded.
(5) Where liability is excluded or limited, this also applies in favour of the Provider's legal representatives, employees and agents.
(6) In the case of data loss, the Provider is liable within the above provisions only to the extent that the User has ensured, through reasonable and regular data backups, that lost data can be restored with reasonable effort.
§ 13 Data protection
The collection and processing of personal data is governed by the Provider's current privacy policy.
§ 14 Add-ons and expansion sets (add-on subscriptions)
(1) Contract formation, term and automatic renewal. Paid add-ons (e.g. 3D figure sets) are concluded as standalone subscriptions with a fixed term of 12 months. The subscription automatically renews for a further 12 months unless terminated by the last day of the current billing period.
(2) Payment processing and immediate suspension upon payment default. The fees due are charged to the stored payment method at the start of each new billing period. If a renewal payment cannot be successfully collected on the due date (e.g. due to insufficient funds, an expired payment method, or a declined payment method), the User is immediately in default. Upon the occurrence of payment default, or upon the regular expiry of a terminated subscription, active and write access to the affected add-ons is suspended with immediate effect and switched to read-only mode (paragraph 5). Access is restored without delay once payment has been successfully completed.
(3) Dependency on the main contract (coupling & automatic termination). Purchasing and using add-on subscriptions in accordance with the contract requires an active, uninterrupted main subscription to the SYSLIA application. If the User terminates the main subscription, this termination automatically and simultaneously constitutes termination of all linked add-on subscriptions, effective at the end of their respective current billing period. If the main subscription ends before an add-on subscription's term expires, access to the affected add-ons is suspended until the end of the add-on's regular term; no claim exists for a full or pro-rata refund of fees already paid.
(4) Strict non-transferability of licences. The licences acquired are personal and valid exclusively for the User's registered account. Transfer — whether in whole, in part, for consideration, or free of charge — to other accounts, other users, or third parties is excluded. This applies without limitation also in the event of termination, suspension, or ending of the main subscription; any remaining term lapses and remains bound to the account and the individual User.
(5) Restricted use after termination / payment interruption (read-only). To preserve data integrity and the User's documentation obligations (e.g. in the context of coaching or supervision processes), 3D elements from terminated add-ons or add-ons suspended due to payment default remain visually unchanged and visible in existing, already-saved boards. Any further functional use — in particular moving, repositioning, editing, duplicating, or re-adding the affected elements to new boards — is technically excluded until the subscription is successfully renewed.
(6) Technical changes and model maintenance. The Provider is entitled to update, replace, or further develop the digital 3D content contained in the sets (including geometries, meshes, textures, and shaders) as part of ongoing platform and performance optimisation, provided that the essential character and intended use of the set are preserved.
§ 14a Backlink exchange program
(1) Customers with an active subscription on the Standard plan or higher may voluntarily join the backlink exchange program: the User enters their own website's name and address in their profile and undertakes to place a visible link to syslia.de on that website. In return, the Provider lists the User's website with a link back on a public page (syslia.de/unsere-kunden).
(2) The Provider checks automatically and regularly whether the agreed backlink is still in place. If it is repeatedly not found, the Provider notifies the User by email and removes the listing after internal review. There is no entitlement to the continuation of the listing.
(3) The User may end their participation at any time, informally, in their profile; their listing is then promptly removed from the public page. This program does not involve any monetary compensation.
§ 15 Final provisions
(1) The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods, unless mandatory consumer protection provisions of the state in which the consumer has their habitual residence preclude this.
(2) If the User is a merchant, a legal entity under public law or a special fund under public law, the exclusive place of jurisdiction for all disputes arising from or in connection with the contractual relationship is Kassel, Germany.
(3) Should individual provisions of these Terms be wholly or partly invalid or unenforceable, the validity of the remaining provisions shall not be affected.
