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. A new project room can be tested free of charge for up to 30 days. Thereafter the project price must be booked in order to continue using it; otherwise the project room is switched to read access. Unused trial days are not refunded.
  3. The project price is paid in 20 monthly instalments: two instalments on booking, the remaining 18 from the start of construction. Start of construction is the point at which an invoice in cost groups 300 to 600 (DIN 276) is first booked in the project room, but no later than 36 months after booking; the customer may also report the start of construction themselves. We inform the customer before the 36-month deadline is reached; on request the deadline can be extended.
  4. The amount of the monthly instalment is determined by the project's cost forecast across cost groups 200 to 700: up to €2M under the Small plan, above that under the Standard plan. The cost forecast is the sum across all cost line items of the project; for each cost line item, the highest of the following values applies: the budget defined, the total contract value, the amount invoiced and the forecast recorded. The cost forecast is determined monthly on the debit date; a change of plan applies exclusively to future instalments. Projects with a cost forecast above €20M require a separate agreement.
  5. Where a booking is made under the Small plan and the project is later classified under the Standard plan (or vice versa), the instalments paid on booking are credited against the instalments of the applicable plan.
  6. From the start of construction, the customer may pay the remaining instalments in one go; in that case the number of remaining instalments is reduced by two.
  7. Organisation plans are billed monthly or annually in advance. Project rooms can be created and used before the start of construction at no additional cost. Projects count towards the total volume (up to €50M) with their cost forecast (cost groups 200–700) from the start of construction until they are marked as completed. The organisation plan covers up to 20 concurrently running project rooms and a total forecast across all project rooms of up to €100M; if these are exceeded, we will get in touch to agree an adjusted plan.
  8. If a follow-on or additional plan (such as your own brand) 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.
  9. In the event of late payment, we reserve the right to restrict access to the services.

6. Contract term and termination

  1. A project contract ends on payment of the 20th instalment or on closure of the project by the customer. On closure, instalments not yet due cease to apply; instalments already paid are not refunded. The right to extraordinary termination for good cause remains unaffected.
  2. Organisation plans can be terminated at the end of the respective billing period.
  3. After a project is completed, read access remains available free of charge for 5 years (warranty phase).
  4. Once those five years have elapsed, the project data is deleted after prior notice by email (at least 3 months), unless the customer has exported it beforehand or books the project again.
  5. Should we discontinue the service, we will give at least 6 months' notice and ensure that all project data can be exported until then.

7. Customer obligations

The customer undertakes:

8. Support

  1. We support one contact person named by the customer, per organisation — under the project plan, per project room — by email on working days.
  2. Supporting further users, in particular clients, planners and contractors whom the customer invites into a project room, is the customer's responsibility.
  3. There is no entitlement to telephone support or to response times unless separately agreed.

9. 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.
  4. Insofar as we process personal data on behalf of the customer in the course of the services, the data processing agreement (DPA) in the version valid at the time the contract is concluded forms part of this contract. The DPA governs the subprocessors we use and the procedure for changing them.

10. 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.

11. 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.

12. Transfer of rights and obligations

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

13. 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.

14. 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.
