Terms of Use for the onesto App for Microsoft Teams
Effective date: 6.8.2026
Provider: onesto GmbH
Important: The App is a business-to-business service and is not offered to the general public. It may be used only by organizations that have a valid agreement covering the App and by users authorized by those organizations.
1. Scope and acceptance
These Terms of Use (the “Terms”) govern access to and use of onesto, including its Microsoft Teams tab, interface, integrations and related components (collectively, the “App”), provided by onesto GmbH, with registered office at Augsburger Straße 14, 86551 Aichach, Germany (“Provider”, “we”, “us” or “our”).
By accessing or using the App, you confirm that you are an Authorized User and that you will use the App in accordance with these Terms. If you are not an Authorized User, or if the organization on whose behalf you access the App does not have a valid Customer Agreement, you must not use the App.
2. Business customers and Authorized Users
The App is available only to a company or other legal entity that has entered into a valid written agreement covering the relevant service with the Provider or with an authorized reseller or partner (the “Customer Agreement”). An “Authorized User” is an employee, contractor or other individual whom that customer has authorized to use the App within the scope of the Customer Agreement.
You must use the App solely for the internal business purposes of the customer that authorized you. You must keep your account and authentication credentials secure and must promptly report suspected unauthorized access to the customer’s administrator or to the Provider.
3. Relationship with the Customer Agreement
The Customer Agreement governs the commercial relationship, subscription, service levels, fees, data-processing commitments, warranties, liability, term and termination applicable to the App and the underlying service. These Terms do not create a separate subscription or payment obligation for an individual Authorized User.
If there is any conflict between these Terms and the applicable Customer Agreement, the Customer Agreement prevails. Where the customer purchased the service through an authorized reseller or partner, the relevant reseller or partner agreement and any applicable agreement between the Provider and the customer determine the customer’s rights to use the App.
4. Right to use the App
Subject to the Customer Agreement and these Terms, the Provider grants Authorized Users a limited, non-exclusive, non-transferable and revocable right to access and use the App during the applicable subscription term. No ownership rights are transferred.
The Microsoft Teams version of the App is an access channel to the Provider’s existing service. Availability through Microsoft Teams or Microsoft Marketplace does not expand the scope of the license, subscription or services stated in the Customer Agreement.
5. Acceptable use
You must not, and must not permit anyone else to:
- access or use the App without authorization or outside the scope of the Customer Agreement;
- interfere with, disrupt or circumvent the security, integrity or operation of the App or related systems;
- introduce malicious code, conduct vulnerability testing without prior written authorization, or attempt to gain unauthorized access to any account, data or system;
- copy, modify, reverse engineer, decompile or create derivative works from the App, except to the limited extent that applicable law expressly permits such activity;
- use the App to violate applicable law, third-party rights or the customer’s internal policies; or
- resell, sublicense or make the App available to a third party except as expressly permitted in the Customer Agreement.
6. Customer content and personal data
The customer and its Authorized Users are responsible for the accuracy, lawfulness and appropriateness of information and content submitted through the App (“Customer Content”) and for ensuring that they have the rights and permissions necessary to provide it.
The Provider processes personal data in accordance with the applicable Customer Agreement, any applicable data-processing agreement, and the Provider’s Privacy Policy available at https://public.onesto.de/privacy-police-ms-teams-app/. Authorized Users should not submit information that the customer has not approved for processing through the service.
7. Intellectual property
The App, its software, design, documentation, trademarks and all related intellectual property rights are owned by the Provider or its licensors. Except for the limited right of use expressly stated in these Terms or the Customer Agreement, no rights are granted to the customer or any Authorized User. Customer Content remains subject to the ownership provisions of the Customer Agreement.
8. Microsoft Teams and third-party services
Use of Microsoft Teams, Microsoft 365 and other third-party services is governed by the terms between the customer or Authorized User and the relevant third-party provider. Microsoft is not a party to these Terms or the Customer Agreement solely because the App is available through Microsoft Teams or Microsoft Marketplace.
The Provider is responsible for the App, but not for Microsoft Teams, Microsoft 365 or other third-party products and services. Their availability, security and functionality are controlled by their respective providers. References to Microsoft products do not imply sponsorship or endorsement by Microsoft.
9. Availability, changes and support
The availability, maintenance, support and service levels for the App are governed by the Customer Agreement. The Provider may update or modify the App to improve functionality, security or compliance, provided that any material contractual commitments remain governed by the Customer Agreement.
Support requests should be submitted through the support channel specified in the Customer Agreement or at https://public.onesto.de/en/support/.
10. Suspension and termination
Access may be suspended or terminated if the Customer Agreement expires or is terminated, if the customer or an Authorized User materially breaches the applicable terms, if suspension is reasonably necessary to protect the security or integrity of the App, or as otherwise permitted by the Customer Agreement or applicable law.
When authorization ends, the Authorized User must stop using the App. Provisions that by their nature should survive termination, including provisions concerning intellectual property, restrictions, liability and interpretation, will survive to the extent applicable.
11. Warranties and liability
Warranties, disclaimers, remedies, exclusions and limitations of liability relating to the App are set out in the applicable Customer Agreement. To the extent that no Customer Agreement provision applies to a particular matter, the App is provided “as is” and “as available” to the maximum extent permitted by applicable law, without warranties beyond those that cannot lawfully be excluded.
Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law.
12. Changes to these Terms
The Provider may update these Terms to reflect changes to the App, applicable law or certification requirements. The current version will be published at https://public.onesto.de/en/terms_of_use/ with its effective date. Material changes will be communicated as required by the Customer Agreement or applicable law. Changes to these Terms do not amend negotiated provisions of a Customer Agreement unless agreed in accordance with that agreement.
13. Governing terms and contact
The governing law and dispute-resolution provisions in the applicable Customer Agreement apply to the use of the App. If no such provisions apply, these Terms are governed by the laws of Germany, excluding its conflict-of-laws rules, and the courts of Augsburg will have jurisdiction, subject to any mandatory law.
