Terms of Service for Parking Providers – Altora ParkBook

The following three documents form part of the Altora ParkBook platform contract and are accepted as binding upon digital order submission.

Altora ParkBook Software Usage Agreement – Contract Terms

As of: November 2026

Preamble

Altora develops and operates, under the name “Altora ParkBook” (hereinafter “ParkBook” or “Software”), web-based parking software for operators of airport car parks, valet parking services, shuttle car parks and multi-storey car parks. ParkBook comprises in particular an online booking portal under the Provider's domain, a parking dashboard for managing bookings, prices and parking areas, and functions for mobile check-in and check-out. The Provider operates parking areas and wishes to use ParkBook to manage its parking operations and to receive direct bookings from its end customers under its own brand. For this purpose it has selected one of the ParkBook packages via the online order form on www.altora-tech.de (hereinafter “selected package”). This agreement governs the provision and use of the Software. Any existing or future partner agreement between the parties on the brokerage of parking spaces via the “Friend-Park” platform remains unaffected by this agreement; both agreements are legally independent.

§ 1 Subject Matter

(1) The subject matter of this agreement is the provision of the ParkBook software in the selected package for use via the internet (software as a service), limited to the term of the agreement, together with the related setup and technical support by Altora. (2) The Software is operated on servers of Altora or of hosting service providers commissioned by Altora. The source code is not provided and no installation takes place at the Provider. ParkBook is a web app and is used via a current internet browser on PC, tablet and smartphone. (3) The exact scope of functions and the prices of the selected package are set out in Annex 1. Services beyond the selected package are not owed unless agreed separately. (4) Annex 1 (service description and prices), Annex 2 (data processing agreement) and Annex 3 (privacy policy for the booking portal) form part of this agreement. In the event of contradictions, the main agreement takes precedence over the annexes unless expressly stated otherwise.

§ 2 Scope of Services

(1) Altora provides the Provider with the functions included in the selected package, which are listed in Annex 1. (2) Functions not included in the selected package according to Annex 1 can be added by switching to a higher package in accordance with § 6 (6). (3) The basic setup (setting up the Provider account, connecting the domain, creating parking areas and price models according to the Provider's specifications) is included in the setup fee according to Annex 1. The basic setup is usually completed within a few days after all required information has been received from the Provider. (4) The import of existing bookings from other portals (e.g. Parkos, ich-parke-billiger and others) is set up at the Provider's request at the import price according to Annex 1. An import requires that a suitable interface or a permissible data export of the respective portal is available. (5) Altora is entitled to further develop, update and adapt the Software, provided that the core functions agreed in the selected package are not significantly restricted.

§ 3 Operation, Faults and Support

(1) Altora does not owe any particular availability of the Software. The Provider acknowledges that technical faults, outages and software errors (bugs) can occur in software; this is part of the normal operation of software and does not in itself constitute a breach of duty by Altora. (2) If technical faults or software errors occur, Altora fixes them as quickly as possible. Fixing the error is the only service Altora owes in the event of a fault. The Provider shows understanding for this and supports Altora with as precise a description of the error as possible. (3) Altora provides support by email to info@altora-tech.de on working days (Monday to Friday, excluding public holidays in North Rhine-Westphalia) during normal business hours. Faults that significantly impair booking or check-in operations are handled with priority. (4) Altora endeavours to make regular data backups. The Provider is responsible for regularly backing up data that is important to it (in particular booking lists and handover reports) itself via the Software's export functions.

§ 4 Import and External Web Services

(1) For importing bookings from other portals or connecting other external web services (hereinafter “external services”), the Provider supplies Altora with all required access data, in particular import links, API keys, user names, passwords and interface descriptions. The Provider is responsible for being entitled to use these accesses and to pass the data on to Altora. (2) External services are operated by third parties and are outside Altora's sphere of influence. Altora assumes no responsibility and no liability for their availability, functionality, data quality and changes, for connection problems, expired, blocked or incorrect keys and access data, or for bookings that are therefore not imported, imported late, twice or incorrectly. (3) If import links, API keys, access data or the interface of an external service change, the Provider informs Altora without delay and provides the new data. Until the new data is received, the import may not work or may work only to a limited extent; Altora is not responsible for this. (4) Altora adapts to normal changes of an external service (in particular new keys, new access data or changed links with an unchanged interface) free of charge. (5) Major changes of an external service that require a new connection (in particular a new or fundamentally changed interface, a new data format or a change of the external service provider) are charged like a new setup at the import price of the selected package according to Annex 1. Altora informs the Provider of the costs in advance; the adaptation is only carried out after the Provider's consent in text form.

§ 5 Rights of Use

(1) For the term of this agreement, Altora grants the Provider the non-exclusive, non-transferable and non-sublicensable right to use the Software within the scope of this agreement for its own business purposes. The Provider may set up user accounts for its employees. (2) All rights to the Software, in particular copyrights and trademark rights, remain with Altora. The Provider is not entitled to copy, modify, reverse engineer or make the Software available to third parties, unless this is mandatorily permitted by law. (3) The content and data entered by the Provider (in particular parking areas, prices, texts, images, booking and customer data) remain with the Provider. The Provider grants Altora the rights to this content required to perform the agreement.

§ 6 Fees and Payment

(1) For the use of the Software, the Provider pays the monthly fee of the selected package according to Annex 1. All prices are net, plus statutory VAT. The number of bookings is unlimited; no commission per booking is charged. (2) For the basic setup, the one-time setup fee stated in Annex 1 for the selected package is charged, if provided for. (3) For the import of existing bookings from other portals, the import price per setup stated in Annex 1 for the selected package is charged – only if the Provider orders it. (4) The obligation to pay the monthly fee begins upon conclusion of the agreement. The setup fee is charged with the first invoice. Partial months are charged pro rata. (5) The monthly fee is invoiced monthly in advance and is payable without deduction within 14 days of receipt of the invoice. One-time fees are invoiced after the respective service has been provided. Invoices are sent electronically to the Provider's email address. Payments are made by bank transfer to the account of Altora Technologies UG (haftungsbeschränkt), IBAN DE29 3007 0207 0089 7694 00, BIC DEUTDEDDP06, stating the invoice number. (6) Package change: The Provider may switch to a higher package at any time in text form (in accordance with the current service description and price list on Altora's website). The change takes effect when the higher package is activated; the fee is charged pro rata from that date. (7) Referral discount: The Provider's contract number is also its referral code. If a parking provider recommended by the Provider successfully concludes a ParkBook agreement with Altora stating this code, the Provider receives a one-time 50 % discount on its next invoice for the monthly fee. This requires that the recommended parking provider was not already a customer of Altora. (8) If the Provider is more than 30 days in arrears with a payment, Altora is entitled, after prior notice in text form with a period of at least 14 days, to block access to the Software until full payment. Bookings of end customers already confirmed remain available to the Provider as a data export on request. Statutory rights in the event of default remain unaffected. (9) Altora may adjust the fees with at least six weeks' notice in text form. If the Provider does not agree to the adjustment, it may terminate the agreement extraordinarily with effect from the date the adjustment takes effect. Altora informs the Provider of this right in the notice.

§ 7 Obligations of the Provider

(1) The Provider supplies Altora completely and in good time with all information required for the setup (in particular parking areas, prices, additional services, operating hours, company data, logo and legal texts). (2) The Provider owns the domain it uses or is entitled to use it and bears the costs of registering and managing the domain. It makes the DNS settings required for the connection according to Altora's specifications or has them made. (3) The Provider is responsible for the content of its booking portal, in particular for the accuracy of its prices and offers, for a proper legal notice, a privacy policy, general terms and conditions and cancellation terms towards its end customers, and for compliance with pricing regulations. (4) The Provider is the sole contractual partner of its end customers for the parking, shuttle, valet and other services. Altora does not become a party to the contracts concluded via the booking portal and assumes no responsibility for their performance, in particular not for the safekeeping of vehicles or for damage to vehicles. (5) The Provider keeps access data secret, grants user rights only to authorised persons and informs Altora without delay if it suspects misuse of its access. (6) The Provider uses the Software only in accordance with applicable law and ensures that no unlawful content is published via the booking portal. (7) The Provider is itself responsible for its bookings. It regularly checks incoming bookings, prices, occupancy and capacities in the dashboard. Altora assumes no responsibility for booking problems, in particular not for double bookings or overbookings, incorrectly calculated or stored prices, undelivered emails or messages, missing or lost bookings, or disputes with end customers.

§ 8 Data Protection and Provider Data

(1) Insofar as Altora processes personal data on behalf of the Provider within the scope of this agreement (in particular data of end customers, vehicle data, vehicle photos, signatures and data of the Provider's employees), the Provider is the controller and Altora the processor within the meaning of Art. 28 GDPR. The details are governed by the data processing agreement in Annex 2. (2) The Software offers automatic deletion periods for vehicle photos with a warning in the dashboard. Determining appropriate deletion periods is the responsibility of the Provider as controller. (3) The Provider can retrieve its data during the term of the agreement via the Software's export functions (e.g. handover reports as PDF, photos individually or as ZIP). After the end of the agreement, Altora provides the Provider, on request made in text form within 30 days after the end of the agreement, with an export of its booking data in a common format. The Provider's data is then deleted unless statutory retention obligations prevent this.

§ 9 Software Errors

(1) Altora provides the Software with the functions described in § 2 and Annex 1. Altora does not warrant any particular freedom from errors or uninterrupted operation. (2) The Provider reports errors without delay in text form with as precise a description as possible. Altora fixes reported errors as quickly as possible; Altora may also provide a workaround for this purpose. (3) Further claims of the Provider due to errors of the Software, in particular for a reduction of the fee or damages, are excluded to the extent permitted by law. Altora's strict liability for errors already existing at the time of contract formation (§ 536a (1) alt. 1 German Civil Code) is excluded. The Provider's right to terminate the agreement under § 11 remains unaffected.

§ 10 Liability

(1) Altora assumes no liability and pays no damages for losses arising in connection with the use of the Software. This applies in particular to technical faults, outages and software errors, booking problems (§ 7 (7)), connection and key problems with external services (§ 4), lost bookings, revenue or profits, data loss, the performance of the Provider's services towards its end customers and damage to end customers' vehicles. In the event of technical errors, Altora's obligation is limited to fixing the error in accordance with § 3 (2) and § 9 (2). (2) The exclusion of liability under para. 1 does not apply where liability is mandatory by law, in particular in the event of intent and gross negligence, for damage resulting from injury to life, body or health, and under the Product Liability Act. (3) Should an exclusion of liability under para. 1 not be permitted by law in an individual case, Altora's liability – except in the cases of para. 2 – is limited to the typical, foreseeable damage and in amount to the fees paid by the Provider in the three months preceding the damaging event. (4) The Provider indemnifies Altora against third-party claims based on unlawful use of the Software by the Provider, on content entered by the Provider or on the performance of the Provider's services towards its end customers, insofar as the Provider is responsible for this.

§ 11 Term and Termination

(1) The agreement is concluded upon completion of the online order and the Provider's digital signature; no countersignature by Altora is required. The agreement runs for an indefinite period. (2) Either party may terminate the agreement with 30 days' notice to the end of a month in text form (e.g. by email to info@altora-tech.de). There is no minimum term. (3) The right to extraordinary termination for good cause remains unaffected. Good cause for Altora exists in particular if the Provider is in arrears with at least two monthly fees or uses the Software unlawfully despite a warning. (4) Fees already paid for one-time services are not refunded at the end of the agreement. Monthly fees paid in advance for periods after the end of the agreement are refunded pro rata.

§ 12 Confidentiality

(1) The parties treat all confidential information of the other party obtained within the scope of this agreement, in particular business, price and customer data, access data and technical information about the Software, as confidential and use it only to perform this agreement. (2) The obligation does not apply to information that is publicly known or becomes known without breach of this agreement, or to disclosures based on statutory or official obligations. It applies during the term of the agreement and for three years after its end. (3) Altora may name the Provider as a reference customer after prior consent in text form.

§ 13 Final Provisions

(1) Amendments and additions to this agreement require text form; this also applies to any amendment of this text form requirement itself. (2) General terms and conditions of the Provider do not apply, even if Altora does not expressly object to them. (3) The Provider may only transfer rights and obligations under this agreement to third parties with Altora's consent. (4) The Provider may only set off undisputed or legally established claims. (5) The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods. (6) If the Provider is a merchant, a legal entity under public law or a special fund under public law, the exclusive place of jurisdiction is – to the extent permitted by law – Altora's registered office. (7) Should a provision of this agreement be or become invalid, the validity of the remaining provisions remains unaffected. The statutory provisions take the place of the invalid provision.

Booking data is processed in particular for: carrying out the booking; sending the booking confirmation; communication about the booking; handling changes and cancellations; customer support; performing the services offered by the parking provider; payment processing, where offered; handling complaints and damage reports; and fulfilling statutory obligations. The legal basis is in particular Art. 6(1)(b) GDPR, insofar as the processing is necessary for the performance of a contract or pre-contractual measures. Insofar as statutory retention obligations exist, processing additionally takes place on the basis of Art. 6(1)(c) GDPR.

5. Technical Provision by Altora

Altora Technologies provides the technical infrastructure for the booking system. Insofar as Altora processes personal data exclusively on behalf of the respective parking provider, this is done on the basis of a corresponding data processing agreement under Art. 28 GDPR.

7. Provider Information

Information about the respective parking provider may be used within Altora products and services. This may include, for example: the Provider's name; description; prices; images; availability; service information; reviews.

8. Reviews

After a booking, the customer may leave a review of the parking provider. Reviews are attributed to the respective provider. A review may be displayed within other platforms operated by Altora, provided it remains clearly attributed to the originally reviewed provider. In a public display, no unnecessary personal data of the customer is generally published.

9. Email Communication

The email address provided in connection with a booking may be used for necessary transaction-related communication. This includes, for example: booking confirmation; changes; cancellations; important information about arrival; information about returning the vehicle; and security-related or technically necessary notices.

10. Advertising by Email

Altora may advertise its own offers, parking comparisons, booking offers, and comparable own services by email, where an appropriate legal basis exists. Insofar as consent is required, it is obtained voluntarily and separately from the actual booking. Consent may be withdrawn at any time with effect for the future. Every such marketing email contains a simple option to unsubscribe.

11. Cookies and Comparable Technologies

The booking portal may use cookies and comparable technologies. A distinction is made between technically necessary technologies and optional technologies. Technically necessary technologies may in particular be used for: session management; the shopping cart or booking process; security functions; storage of technical settings; load balancing; and protection against misuse. Optional analytics, marketing, or comparable technologies are used only where the required consent or another legal basis exists.

12. Analytics and Statistics Services

Insofar as analytics or statistics services are used on the respective portal, these are stated in the currently applicable privacy notices or in the consent-management tool. This may, for example, include services from Google or other technical providers.

Personal data is transferred to such service providers only insofar as necessary for the respective service and legally permissible. Where a service provider processes personal data on behalf of a controller, it is engaged in accordance with statutory requirements.

14. No Rental or Sale of Personal Data

Personal data is not sold or rented for the purpose of making the Provider's own customer data available to third parties. A transfer may nevertheless be necessary where: a technical service provider is required for the operation of the platform; a payment service provider processes a payment; a legal obligation exists; an authority or court is entitled thereto; or another transfer is legally permissible or required.

15. Retention Period

Personal data is generally stored only for as long as necessary for the respective purpose. In addition, data may be stored insofar as statutory retention obligations exist or the data is needed to assert, exercise, or defend legal claims.

16. Rights of Data Subjects
