1.2 Flexling's Services are exclusively directed at consumers within the meaning of Section 13 of the German Civil Code (BGB), i.e. natural persons who use the Services for personal, non-commercial purposes. Use by entrepreneurs within the meaning of Section 14 BGB is not permitted. By registering, the User confirms that they use the Services exclusively for personal purposes.

1.3 The version of these Terms valid at the time of contract conclusion shall apply. Conflicting or deviating terms of the User are not accepted.

1.4 The contract language is German.

2. Description of Services

2.3 The Services are provided as digital services within the meaning of Section 327(2)(2) BGB and are exclusively directed at private individuals for personal use.

3. Conclusion of Contract

3.1 The presentation of the Services on flexling.com does not constitute a legally binding offer but an invitation to submit an offer (invitatio ad offerendum).

3.2 By registering a user account or subscribing to a paid plan, the User submits a binding offer to enter into a usage agreement. The contract is concluded when Flexling accepts this offer by activating the account or subscription.

3.3 The contract text is not stored by Flexling and is no longer accessible via the website after contract conclusion. The User should save or print these Terms and the cancellation policy before contract conclusion. A copy of these Terms will be sent to the User by email after contract conclusion.

3.4 As the Services are exclusively directed at consumers, the statutory consumer protection provisions apply in full.

4. Cancellation Policy

As Flexling is exclusively directed at consumers, the following cancellation policy applies to all Users.

8.0 Notice on AI Interaction (pursuant to Art. 50 EU AI Act): All features on flexling.com that respond to your input are operated by automated AI systems. You always interact with AI systems, not with human staff. This notice is provided in compliance with the transparency obligations of Regulation (EU) 2024/1689 (EU AI Act). AI-generated content (texts, translations, other outputs) may be marked as AI-generated. Further details can be found in the respective feature view within the application.

8.1 AI-generated content may be inaccurate, incomplete, or misleading. Flexling does not warrant the accuracy, completeness, or suitability of AI-generated outputs for any particular purpose. The User is responsible for independently reviewing and using this content.

8.2 When using AI-powered features, your inputs are transmitted to external AI providers for processing. For details on the providers used, the legal bases for data transfers, and the safeguards in place, please refer to our Privacy Policy at flexling.com/legal/privacy.

No payment method is required for the free plan.

9.2 Paid Subscriptions

Paid plans are offered as subscriptions (monthly or annually). Current prices are available at flexling.com/pricing. All prices are quoted in Euros.

Note on VAT: Pursuant to Section 19 of the German VAT Act (UStG) (small business regulation), no VAT is charged and therefore not separately shown.

9.3 Subscription Renewal and Cancellation

Subscriptions automatically renew for the respective booked period (monthly or annually) unless cancelled before the end of the current billing period via the user account. After cancellation, access remains until the end of the already paid period.

9.4 Refunds

The statutory right of withdrawal under Section 4 of these Terms remains unaffected. Beyond that, there are no further goodwill claims for refunds. Refunds under the right of withdrawal are processed via the originally used payment method.

9.5 Late Payment

In the event of late payment, Flexling reserves the right to suspend access to paid features until the outstanding amount has been settled.

10. Availability and Maintenance

10.1 Flexling endeavors to provide the Services with maximum reliability. However, 100% availability cannot be guaranteed. Scheduled maintenance will be carried out during periods of low usage whenever possible.

10.2 Flexling reserves the right to adjust, expand, or restrict the scope of the Services, provided this is reasonable for the User and does not constitute a material deterioration for ongoing paid subscriptions. In the event of restrictions to the scope of paid subscriptions, the User will be notified at least four weeks in advance.

11. Liability

11.1 Flexling is fully liable for damages arising from injury to life, body, or health, as well as for damages caused intentionally or through gross negligence.

11.3 Beyond this, Flexling's liability for slightly negligent breaches of duty is excluded.

11.4 Flexling assumes no liability for the content of AI-generated outputs. The User is responsible for independently reviewing and using this content. This does not apply to damages resulting from intentional or grossly negligent malfunction of the Service.

11.5 The above limitations of liability do not apply to claims under the German Product Liability Act or for fraudulently concealed defects.

12. Data Protection

The protection of your personal data is important to us. For details, please refer to our Privacy Policy: https://flexling.com/legal/privacy

13. Term and Termination

13.1 The usage agreement for the free plan runs for an indefinite period and may be terminated by either party at any time without notice.

13.2 Paid subscriptions run for the respective booked period and renew automatically unless cancelled (see Section 9.3).

13.3 Flexling has good cause for extraordinary termination, in particular in the event of:

• repeated or serious violations of these Terms,
• commercial use contrary to Sections 1.2 and 6,
• late payment of more than 14 days despite a reminder,
• misuse of the Services or attempts to harm third parties.

13.4 After termination, the User's data will be deleted in accordance with the Privacy Policy.

14. Amendments to These Terms

14.1 Flexling reserves the right to amend these Terms with effect for the future, insofar as this is necessary to adapt to changed legal or regulatory requirements or to clarify existing provisions, and no material change to the main contractual obligations occurs.

14.2 Amendments affecting the main contractual obligations or material contractual terms will only become effective with the User's express consent. The User will be separately requested to provide such consent.

14.3 In the event of any amendment under Section 14.1, the User is entitled to terminate the contract extraordinarily as of the date the amended Terms take effect. Flexling will expressly draw attention to this right in the amendment notice. In the case of paid subscriptions, a pro-rata refund for the unused period will be provided in the event of such termination.

15. Applicable Law and Jurisdiction

15.1 The law of the Federal Republic of Germany shall apply, excluding the UN Convention on Contracts for the International Sale of Goods (CISG).

15.2 As the Services are exclusively directed at consumers, the mandatory consumer protection law of the User's country of residence shall additionally apply insofar as it is more favorable for the User.

15.3 For consumers, jurisdiction is determined by the statutory provisions.

16. Dispute Resolution

The European Commission provides a platform for online dispute resolution (ODR): https://ec.europa.eu/consumers/odr

Flexling is not obligated and generally not willing to participate in dispute resolution proceedings before a consumer arbitration board. This notice is provided pursuant to Section 36(1) of the German Consumer Dispute Resolution Act (VSBG).

17. Severability Clause

Should any provision of these Terms be or become wholly or partially invalid or unenforceable, this shall not affect the validity of the remaining provisions. The invalid or unenforceable provision shall be replaced by the statutory regulation (Section 306 BGB).

18. Miscellaneous

18.1 These Terms constitute the entire agreement between the User and Flexling and supersede all prior agreements.

18.2 Flexling is entitled to transfer rights and obligations under this contractual relationship to a legal successor. The User will be informed of this in good time and has a special right of termination in this case. In the case of paid subscriptions, a pro-rata refund for the unused period will be provided in the event of such termination.
