Terms and Conditions – BlitzFin

BlitzFin terms and conditions – the terms governing use of the construction cost controlling platform.

Please note: this English text is a convenience translation. The German version (AGB) is the legally binding one.

1. General and conclusion of contract

These terms and conditions apply to contracts for the use of the software-as-a-service products we provide under the “BlitzFin” brand:

Differing terms and conditions of the customer do not become part of the contract unless their applicability is expressly agreed.

2. Formation of contract

NOTE: paid plans are always clearly identified as such during the ordering process. The demo and setup phase is free of charge.

  1. The presentation of plans on this website does not constitute a legally binding offer.
  2. By clicking the relevant order button, customers submit an offer to enter into a contract.
  3. The offer is binding for one working day.

3. Right of withdrawal

Consumers have a right of withdrawal (Widerrufsrecht) in accordance with statutory provisions. In the case of services, the right of withdrawal expires where the trader has fully performed the service and only began performing it after the consumer gave their express consent to do so.

4. Availability of the services

We aim for service availability of 99.5%. Maintenance work, force majeure and other unforeseeable events may affect availability.

5. Prices and payment terms

  1. All prices are exclusive of statutory VAT.
  2. Billing is per project or per year, in advance.
  3. A new project room can be tested free of charge for up to 30 days. To continue using the services without interruption, a paid plan must be booked within this period; otherwise the project room is switched to read access once the period expires. The paid billing period begins on booking — irrespective of whether this takes place during or after the trial period. Unused trial days are neither refunded nor credited.
  4. Billing for a project plan begins with the first real invoice in the project room.
  5. If a follow-on plan is booked while a paid or granted period is still running, the new billing period only begins when that period ends; time already paid for is not lost. The date of the first debit is shown during the ordering process.
  6. In the event of late payment, we reserve the right to block access to the services.

6. Contract term and termination

  1. Project contracts run for at least one month. The right to extraordinary termination for good cause remains unaffected.
  2. Where payment is made annually in advance, dormant months are appended at the end; no refund is made.
  3. After a project is completed, read-only access remains available free of charge for 5 years (warranty phase).

7. Customer obligations

The customer undertakes:

8. Data protection and data security

  1. We undertake to comply with data protection legislation.
  2. Data processing takes place in accordance with our privacy policy.
  3. The customer remains the owner of their data and can extract it at any time using the export function.

9. Warranty

  1. We warrant that the services will be provided in accordance with the contract.
  2. In the event of defects, we will first attempt remedial action.
  3. Further warranty claims are governed by statute.

10. Liability

  1. We are liable for damages only in cases of intent and gross negligence.
  2. Liability for slight negligence is limited to the breach of material contractual obligations.
  3. Liability is limited in amount to the foreseeable damage.

11. Transfer of rights and obligations

The customer may transfer their rights and obligations under this contract to third parties only with our written consent.

12. Final provisions

  1. German law applies, excluding the UN Convention on Contracts for the International Sale of Goods.
  2. The place of jurisdiction is Hannover.
  3. Should individual provisions be invalid, this does not affect the validity of the remainder of the contract.

13. Special conditions for the Construction Cost Calculator

  1. Basic use of the Construction Cost Calculator is free of charge. Access is provided by email link after the onboarding form has been completed; calculations created remain stored in the user account.
  2. The Construction Cost Calculator provides non-binding cost estimates based on reference projects and on regional and time-based index values. The results do not replace professional planning, cost calculation or advice; we accept no liability for the estimate corresponding to actual construction costs.
  3. The Construction Cost Calculator may be offered in collaboration with partners (for example architecture or construction firms) and may carry their branding. In all cases, the contracting party for its use remains exclusively blue media labs GmbH.
  4. Paid additional features are clearly identified as such before booking and are billed at the prices displayed there.
