LoDi-Aura licence terms

§ 1 Scope and contracting party

(1) These licence terms apply to the LoDi-Aura software (program, updates, documentation) of Lokstoredigital e.K., Stäffelsbergstraße 13, 76889 Dörrenbach, Germany.

(2) The general terms and conditions of Lokstoredigital apply in addition. In the event of conflict, these licence terms take precedence for the software.

(3) They apply to consumers and businesses alike. Mandatory consumer rights remain unaffected.

(4) The German version is authoritative. Translations are for information only.

(5) Deviating terms of the customer do not apply.

§ 2 Subject of the licence and tiers

(1) The basic scope remains usable without a licence: LoDi devices without a quantity limit, handheld controllers, CV programming, mfx reading, several windows and operating devices, user rights.

(2) The licence tiers are Basic, Standard and Professional. The highest tier purchased applies; each includes the scope of the tiers below it. Which function belongs to which tier is shown on the pricing page at the time of purchase.

(3) Command-station licences (Märklin CS2/CS3, ESU ECoS, Roco/Fleischmann Z21, XpressNet/Lenz) are add-ons to Basic or Standard. Professional includes all command stations. A command-station licence on its own, without a tier, has no effect.

(4) Basic, Standard, Professional and command-station licences are bought once and are valid without time limit. They apply to the release in which they were bought; a release is a major version of LoDi-Aura (for example release 1). All updates of this release are included, at no extra charge and without time limit. When a new release appears, you decide yourself whether to buy it; your existing release keeps running unchanged.

(5) Pionier is an annual licence and is only available together with a Professional licence; without Professional it has no effect. It gives access to beta versions (§ 5) and includes new versions during its term.

(6) A trial licence is available once per Lokstore account. The software states its scope and duration when it is activated.

(7) When a licence expires, operation continues with the existing state. Functions that require a licence can no longer be started anew; the data is kept.

§ 3 Device binding and account

(1) The licence only counts the computer on which the LoDi-Aura Nexus runs. How many such computers can be activated at the same time (device slots) is stated on the product page at the time of purchase and can be seen in the Lokstore account. All other devices on the network that connect to a Nexus need no licence and are allowed in any number: further PCs or Macs with a browser, tablets, phones, LoDi-Con. Anyone who needs more device slots should contact Lokstoredigital.

(2) The licence is bound to the Lokstore account and the device identifier of the computer. Sign-in uses a short code on the portal; the account password is never entered into the software. Without an internet connection, the licence can also be installed as a file that you download from the customer portal.

(3) Without a connection to the portal, the licence keeps running for 14 days.

(4) A change of computer is made through the Lokstore account: a device slot is released and assigned anew.

(5) The software checks licences against signed licence data and prevents older licences from being restored. Circumventing, altering or imitating the licence check is prohibited.

§ 4 Scope of the right of use

(1) The customer receives the simple, non-exclusive right to use LoDi-Aura within the scope of the licence purchased to control their model railway layout (§§ 2 and 3).

(2) Installation on the licensed computer, backup copies and use through operating devices are permitted. Any further reproduction, renting, lending and making available to the public are not permitted.

(3) Decompiling and reverse engineering are only permitted within the statutory limits (§ 69e of the German Copyright Act, UrhG).

(4) Transfer: the licence may be transferred to a third party completely and permanently if the customer deletes the software from their devices and the transfer is carried out in the Lokstore account. Shared or temporary transfer is excluded.

(5) The software and documentation are protected by copyright. Graphics of command-station manufacturers that the software takes over from the customer’s command station (such as locomotive images from an ECoS or CS3) serve only for display at the customer’s site and are not exported by the software.

§ 5 Updates and versions

(1) Within a release, the customer receives all updates at no extra charge. For a release that has been superseded by a new one, Lokstoredigital continues to provide bug fixes for at least two years from the purchase of the licence and for at least twelve months after the next release appears.

(2) The software checks by itself whether a new version is available and shows this. It downloads and installs nothing without the customer’s consent.

(3) Beta versions are only available with a Pionier licence. They are pre-release versions for testing: functions may be incomplete, change or be dropped; data loss cannot be ruled out. Before using a beta version, a backup of the layout data must be made. Rights in respect of defects exist for beta versions only to the extent mandatory by law.

(4) After the Pionier licence expires, the installed beta version keeps running; new versions then come from the regular channel.

(5) If you save your layout with a newer version of LoDi-Aura, the file may no longer open with an older version. This affects, for example, a second computer that still runs the older version. The software tells you so when opening the file and names the version required; then update the older version.

§ 6 Control of the layout

(1) LoDi-Aura controls the layout on the basis of the information in the layout project and the feedback supplied by the connected equipment. The software issues commands and evaluates feedback; the commands are carried out by the layout itself.

(2) Whether the layout follows a command and whether feedback reflects the actual state depends on circumstances outside the software. The software’s displays are derived from these and do not replace watching the layout.

(3) A malfunction or damage on the layout does not in itself constitute a defect of LoDi-Aura. If a software error contributed to it, § 11 applies.

§ 7 Commissioning, supervision and protection against falls

(1) On first commissioning and after changes to the layout or the project, check the affected routes at low speed while watching them. Check the direction of travel, turnout position, occupancy detection and stopping point. If the actual state visibly differs from the display in the track diagram, stop the affected operation until the cause has been found.

(2) A model railway layout is a machine with moving parts and track power. Do not leave the layout running unattended in automatic mode: someone must be able to intervene at any time. The safety device for track power is the emergency stop of the command station or booster; the software’s “All stop” function supplements it and does not replace it.

(3) Secure places where vehicles can fall after a wrong run or a derailment with suitable mechanical protection. This applies in particular to open track ends at the edge of the layout, tracks right at the edge and transitions at removable parts of the layout.

(4) If a reasonable safeguard that would have prevented or reduced the damage is missing at a recognisable danger point, this may reduce the claim for compensation under the statutory rules on contributory negligence.

(5) Back up your layout data regularly. The software creates local snapshots; they do not replace a backup outside the computer.

§ 8 Third-party command stations and devices

(1) LoDi-Aura works with command stations and devices from Lokstoredigital and, depending on the licence, with command stations from other manufacturers (Märklin CS2/CS3, ESU ECoS, Roco/Fleischmann Z21, XpressNet/Lenz). The connection is based on the interfaces published by these manufacturers or observed in operation.

(2) If manufacturers change their firmware or interfaces, interoperation may be restricted. Lokstoredigital endeavours to adapt, but does not owe an adaptation for third-party changes.

(3) Which functions are supported with command stations from other manufacturers – for example feedback modules, locomotive images, function symbols or coaches – depends on the command station concerned. Details can be found in the documentation.

(4) Firmware updates for LoDi devices can be installed through the software. The power supply must not be interrupted during the process; the software points this out.

(5) Rights in respect of defects in separately purchased hardware are governed by the respective purchase contract.

§ 9 Data and connections

(1) Layout data (track plans, vehicles, timetables, logs) is stored on the customer’s computer. Lokstoredigital has no access to it unless the customer uploads it to their Lokstore account themselves (paragraph 4).

(2) The software connects to Lokstoredigital servers for the licence (Lokstore account, device identifier of the computer), for checking for new versions (retrieving a signed version list; the IP address is transmitted in the process) and, at the customer’s request, for the image and vehicle database (locomotive images, decoder data).

(3) The software creates a diagnostic package only at the customer’s request and stores it locally. The customer decides whether to send it to support. Usage data is not transmitted automatically.

(4) The customer can additionally upload their layout project to their Lokstore account, for example as a backup or to open it on another of their computers. The project remains theirs. Lokstoredigital views and uses it only if the customer expressly releases it for that purpose, for example for support or as an example layout; the customer can withdraw the release in the account at any time. Without a release, the storage space serves the customer alone.

(5) Details on the processing of personal data are set out in the Lokstoredigital privacy policy.

§ 10 Third-party components

(1) LoDi-Aura contains third-party libraries under open-source licences, including the Go standard library and Go modules, Wails and Vite. The respective licence terms apply to these components; they are not restricted by these licence terms.

(2) The list of components with their licence texts can be viewed in the software under System → Licence.

(3) Signal and device images come partly from Lokstoredigital products and partly from the customer’s command stations (§ 4 (5)).

§ 11 Rights in respect of defects and liability

(1) The statutory rights in respect of defects apply to defects of LoDi-Aura. Claims for defects in separately purchased hardware remain unaffected.

(2) Lokstoredigital e.K. is liable without limitation for intent and gross negligence and for culpable injury to life, body or health. Claims under the German Product Liability Act, for fraudulent concealment of a defect or under a guarantee given remain unaffected.

(3) In the case of simple negligence, Lokstoredigital e.K. is liable for the breach of essential contractual obligations. These are obligations whose fulfilment makes the proper performance of the contract possible in the first place and on whose observance you may regularly rely. In these cases, liability is limited to the damage that was foreseeable and typical for the contract at the time it was concluded. Otherwise, liability for simple negligence is excluded. The cases of unlimited liability under paragraph 2 are exempt from this.

(4) These rules also apply to breaches of duty by the legal representatives and vicarious agents of Lokstoredigital e.K.

(5) Lokstoredigital is liable for data loss only to the extent that would have occurred with regular backups in accordance with § 7 (5).

§ 12 Term, expiry and blocking

(1) Tier and command-station licences do not end through the passage of time (§ 2 (4)). The Pionier licence ends after twelve months without notice of termination and does not renew automatically.

(2) In the event of proven circumvention of the licence check or use of the same licence on several computers, Lokstoredigital may block the licence. The customer is informed beforehand and given the opportunity to respond.

(3) Should Lokstoredigital ever discontinue the licence portal, customers will receive a licence file in good time with which purchased licences keep running without the portal.

§ 13 Withdrawal for digital content

(1) Consumers have a statutory right of withdrawal when buying in the online shop. The withdrawal instructions are part of the ordering process.

(2) The right of withdrawal also applies to licences provided as a code or in the account. Lokstoredigital does not assert early expiry of the right. Upon withdrawal, the licence is deactivated in the account and the purchase price refunded.

§ 14 Final provisions

(1) German law 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 them of the protection of mandatory provisions of the state in which they reside.

(2) The place of jurisdiction for merchants is the registered office of Lokstoredigital.

(3) Lokstoredigital may change these licence terms for new versions. For a purchased licence, the version in force when the contract was concluded applies; a new version applies when the customer buys a new release or agrees to it.

(4) Should a provision be invalid, the remainder of the contract remains valid.

(5) Version of these licence terms: 14 November 2026.
