Liability for content
As a service provider, I am responsible for my own content on these pages under the general laws pursuant to § 7 (1) DDG. However, pursuant to §§ 8 to 10 DDG, as a service provider I am not obliged to monitor transmitted or stored third-party information or to investigate circumstances that indicate unlawful activity. Obligations to remove or block the use of information under the general laws remain unaffected. Liability in this regard is only possible from the point in time at which knowledge of a specific infringement is obtained. Upon becoming aware of corresponding infringements, I will remove this content immediately.
Liability for links
This offering contains links to external third-party websites, over whose content I have no influence. Therefore, I cannot assume any warranty for this third-party content. The respective provider or operator is always responsible for the content of the linked pages. The linked pages were checked for possible legal violations at the time of linking; unlawful content was not identifiable at that time. Permanent monitoring of the content of the linked pages is not reasonable without concrete indications of an infringement. Upon becoming aware of infringements, I will remove such links immediately.
Copyright
The content and works created on these pages are subject to German copyright law. Reproduction, editing, distribution and any kind of exploitation outside the limits of copyright require my written consent. Downloads and copies of this page are only permitted for private, non-commercial use.
Dispute resolution
Since 20 July 2025, the European Commission no longer provides an online dispute resolution platform. I am neither willing nor obliged to participate in dispute resolution proceedings before a consumer arbitration board.
Data protection
This website does not use cookies, tracking, analytics services, external resources or web fonts. When accessed, the web server logs the usual access data for technical reasons; this data is not merged with other data and serves solely for secure operation. In the web app and the iOS app, only the data that you yourself record or upload (trips, vehicles, expenses, receipts) is processed; it is visible only to your account and is not transmitted to third parties.

📜 Terms of use and disclaimer
§ 1 Scope
(1) These terms apply to the use of the iOS app "OBDRest", the web application "OBDRest Trips" (app.fahrten.fusenigk.de), this website and the associated programming interface (REST API), hereinafter collectively referred to as "Services", offered by the provider named in the Legal notice ("Provider").
(2) By registering or using the Services, the user agrees to these terms. Deviating terms of the user do not apply.
§ 2 Services, free of charge, availability
(1) The services are provided free of charge. There is no entitlement to the conclusion of a usage relationship, to a specific scope of functions or to a specific availability.
(2) The provider is entitled to change, restrict or discontinue the services in whole or in part at any time. If the standard server is discontinued, the provider will, where possible, inform registered users with reasonable notice so that they can export their data.
(3) The services provide measured values, error codes, error descriptions, analyses, consumption, distance and cost information exclusively as non-binding information. They do not constitute automotive-technical, legal or tax advice and do not replace inspection by a specialist workshop or advice from a tax advisor. Tax recognition of the logbook maintained with the services is not assured.
§ 3 LIABILITY
(1) The provider is liable without limitation for intent and gross negligence, for culpable injury to life, body or health, for fraudulent concealment of a defect, within the scope of an assumed guarantee and under the provisions of the Product Liability Act.
(2) Otherwise, the provider's liability – regardless of the legal ground, in particular from contract, tort or strict liability – is excluded. This corresponds to the statutory assessment for gratuitous services (§§ 521, 599 BGB). To the extent that liability for slight negligence nevertheless mandatorily exists, it is limited to the breach of essential obligations whose fulfillment is what first enables the proper use of the services and on whose compliance the user may regularly rely (cardinal obligations), and in amount to the damage foreseeable at the time of contract conclusion and typically occurring.
(3) Subject to paragraph 1, the provider is in particular not liable for damage to vehicles, control units, OBD2 adapters, vehicle batteries or end devices, for data loss, for indirect damage and consequential damage, lost profit, fines, tax back payments and interest, as well as for damage arising from the unavailability of the services or from incorrect, incomplete or delayed information.
(4) The user's claims for reimbursement of expenses, indemnification or recourse against the provider are excluded to the same extent as claims for damages under paragraphs 1 to 3.
(5) The above liability limitations also apply in favor of the provider's legal representatives, employees and vicarious agents.
(6) A change in the burden of proof to the detriment of the user is not associated with the above provisions.
§ 4 OBLIGATIONS AND DUTIES OF THE USER
(1) The user uses the services and an OBD2 adapter at their own responsibility and observes the instructions of the vehicle and adapter manufacturer, in particular regarding quiescent current and vehicle battery.
(2) The app must not be operated by the driver while driving; the provisions of the Road Traffic Regulations, in particular § 23 para. 1a StVO, must be observed.
(3) Deleting the error memory (OBD mode 04) resets readiness tests and can impair the emissions test. It is carried out exclusively at the user's express request and at the user's own risk.
(4) The user is responsible for regularly backing up their data (e.g. export as PDF, CSV, JSON or GPX). If they fail to do so, any damage incurred by them must be taken into account under § 254 BGB.
(5) The user keeps their access data secret and uploads only content that they are authorized to use and that does not infringe third-party rights.
(6) If the user uses their own server or their own implementation of the interface, they are solely responsible for its operation, security and compliance with data protection law.
§ 5 INDEMNIFICATION
The user indemnifies the provider against all third-party claims, including the reasonable costs of legal defense, that these assert against the provider due to an unlawful use of the services attributable to the user or a breach of the obligations under § 4 paras. 5 and 6.
§ 6 TERMINATION
Both parties may terminate the usage relationship at any time without observing a notice period. The user may request the deletion of their account and their data; statutory retention obligations remain unaffected.
§ 7 FINAL PROVISIONS
(1) The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods. Vis-à-vis consumers, this choice of law applies only insofar as it does not deprive them of the protection granted by mandatory provisions of the law of the state in which the consumer has their habitual residence (Art. 6 para. 2 Rome I Regulation).
(2) If individual provisions of these terms are or become invalid in whole or in part, the validity of the remaining provisions remains unaffected. The invalid provision is replaced by the statutory provisions (§ 306 para. 2 BGB).
🚗 SUPPLEMENTARY NOTES
- Calculated values. Consumption, distance, eco-score and cost per kilometer are calculated or estimated values (including from GPS, air mass and fuel receipts) and may deviate from the actual values.
- Demo access. The demo access contains fictitious test data and generated sample receipts; it is read-only and can only be used in the browser.
- Trademarks. Mentioned brand and product names (e.g. Mercedes-Benz, Volkswagen, Vgate) are the property of their owners. There is no business connection to these manufacturers; images of adapters are our own illustrations.
