General Terms and Conditions

1. Scope and contracting party

These General Terms and Conditions (GTC) apply to the use of the software “BOB — Back on Budget” (hereinafter “BOB”) in the web application and in the mobile apps. The provider and your contracting party is KRUPKA Concept GmbH, Grabenstraße 18, 40789 Monheim am Rhein, Germany (hereinafter “we”).

BOB is aimed at consumers (Section 13 of the German Civil Code, BGB) who plan and manage a private construction, renovation or conversion project. Deviating or conflicting terms of users do not become part of the contract unless we expressly agree to their validity in text form.

2. Conclusion of the contract, account and access data

The contract for free use (Free) is concluded when an account is set up. A paid contract is concluded when you select a plan in the ordering process, confirm your obligation to pay and we confirm the order or provide the service.

An account requires a valid email address; you sign in via a sign-in link sent to you by email. You are responsible for protecting access to your email inbox and to your account against access by third parties. If you become aware of any misuse, notify us without undue delay.

One account per person is intended. You can invite other people to a project; their use is likewise governed by these GTC.

3. Description of services

BOB provides a budgeting tool for private construction projects. Depending on the plan booked, this includes in particular: cost planning by trades and cost items, recording of quotes, contracts, change orders, invoices and payments, evaluations and forecasts, notices from the payment guard, a funding overview, document recognition, import and export functions, and reminders.

The specific scope of functions results from the service overview on the pricing page in the version current at the time of booking. BOB is continuously developed further. We may change or extend the scope of functions or discontinue individual functions insofar as this is reasonable for you and does not jeopardise the purpose of the contract; we will announce material restrictions of the booked scope of services in text form at least six weeks in advance. In this case, you have a special right of termination effective at the time of the change.

BOB is software for independent use. Individual support, setting up your project or reviewing your documents by us is not owed.

You use BOB via an internet connection in your web browser — the current versions of Chrome, Edge, Firefox and Safari are supported — or in the BOB apps for iOS and Android once they are available in the respective store; for the apps, the operating system version stated there applies. Depending on your plan, you can export your data as CSV, XLSX and PDF files and import cost plans from XLSX and CSV files.

4. No legal, tax or financial advice

BOB provides no legal advice, no tax advice and no investment or financing advice and must not replace such advice.

In particular, the notices of the payment guard, information on statutory deadlines, warranty and limitation periods, information on the tax treatment of tradespeople's services and all templates, checklists and sample wording are exclusively general information that does not assess your individual case. They are based on the data you have entered and on the legal situation known at the time they were created. Whether and how a rule applies in your case can only be assessed by a person qualified to give legal or tax advice.

You make decisions on payments, conclusion of contracts, terminations, notices of defects, retentions or tax returns on your own responsibility. We recommend obtaining expert advice in case of doubt.

5. Calculations, automatic recognition and data quality

All evaluations, forecasts, totals and warnings in BOB are based on the data that you or invited persons enter, import or upload. You are responsible for the correctness, completeness and timeliness of these entries.

Automatic document recognition and the allocation suggestions work with automated methods and provide suggestions, not verified results. Recognition errors, incomplete readings and incorrect allocations are possible and cannot be avoided completely for technical reasons. Check recognised values before accepting them. We are under no obligation to check your documents.

Forecasts are projections of recorded values and not a commitment regarding actual construction costs. Reference values, ranges and statistical figures come from the sources stated in each case and are marked with source and date; they do not constitute an assurance.

6. Plans, prices and payment

BOB is offered in a free plan (Free) and in paid plans: Pro as a subscription with monthly or annual billing, as well as one-off products with a fixed term (in particular the Build Pass and the Warranty Pass) and usage-based add-on packs. The prices and services applicable at any given time are shown on the pricing page. All prices are final prices including statutory VAT.

Payments are processed via our payment service provider. Subscription fees are due in advance at the beginning of each billing period, one-off products upon conclusion of the contract. If you are in default with a payment, the statutory provisions apply; after prior notice in text form and a reasonable grace period, we may suspend the service until the outstanding amount has been paid. Your data already recorded is retained during this time and remains accessible within the scope of Free.

We may adjust the prices for ongoing subscriptions with six weeks' notice in text form, effective at the end of the respective billing period, in order to offset increased costs for operation, development or upstream services. In the event of a price increase, you may terminate the contract effective at the time the increase takes effect; we will point out this right in the notice. One-off products with a fixed term are not affected by price adjustments.

Add-on packs for document recognition do not expire and are only used once the monthly quota included in the plan has been exhausted. Unused quotas are not paid out.

7. Term and termination

The Free account runs for an indefinite period and can be ended by you at any time without notice.

The Pro subscription with monthly billing initially runs for one month and renews for one further month in each case unless it is cancelled by the end of the current month.

The Pro subscription with yearly billing initially runs for twelve months at the yearly price. After that it continues for an indefinite period and is billed monthly at the monthly price then in force; from that point you can cancel at any time with one month’s notice. It does not renew for twelve months at a time.

You can cancel at any time with one click in your account under “Account → Your plan”; cancellation in text form is also sufficient.

One-off products end automatically when their term expires, without the need for cancellation; there is no automatic renewal.

The right to extraordinary termination for good cause remains unaffected for both parties. Good cause exists for us in particular if you seriously violate clause 9 despite a warning or are significantly in default with payments.

8. Right of withdrawal and early start of performance

As a consumer, you have a statutory right of withdrawal. Details and the model withdrawal form can be found in our withdrawal policy.

We activate paid services immediately after purchase so that you can continue working without waiting. This requires that, before purchasing, you expressly request that we begin performance before the withdrawal period has expired. You make this declaration in the purchase process itself; for legal reasons, it cannot be replaced by these GTC.

Two consequences follow from this: if the service has been performed in full — for example in the case of a credit pack whose recognitions are credited to you immediately — your right of withdrawal expires upon full performance (Section 356(5) no. 2 BGB). If you withdraw before then, you owe us, under Section 357a(2) BGB, a reasonable amount for the service provided up to the withdrawal. The decisive factor is the proportion of the service provided up to that point in relation to the total scope, calculated on the basis of the agreed total price.

In the case of ongoing services — the Pro subscription, the Build Pass and the Warranty Pass — the service has not yet been performed in full on the day of purchase. For these, your right of withdrawal remains in place for the full withdrawal period; the only consequence is the proportionate compensation under the preceding paragraph.

9. Obligations when using BOB

You undertake

• to upload only documents that relate to your own project or for which you hold the necessary rights,
• not to post any unlawful, infringing or harmful content,
• not to access BOB in an automated way to an extent that goes beyond normal use (such as scraping or load tests),
• not to circumvent any security measures, not to introduce malware and not to disrupt operations,
• not to pass on access data and sign-in links to third parties, and
• not to reverse engineer or copy the software or make it available to third parties for use against payment, unless this is permitted by law.

In the event of serious or repeated violations, we may remove the content concerned and block access after prior notice. In the event of imminent danger, we may block access provisionally without notice and will inform you without undue delay afterwards.

10. Rights to content

Your project data and uploaded documents remain your content. We only receive the right to store, process and display them in order to provide the contractual service — including transmission to the processors used for document recognition. Your content is not used for advertising purposes or for training AI models.

The rights to the software, templates, texts, designs and trademarks of BOB belong to us or our licensors. For the term of the contract, you receive a non-exclusive, non-transferable right to use them as intended.

11. Availability and statutory warranty

The statutory warranty rights for digital products apply to BOB (Sections 327 et seq. BGB). If we do not provide BOB or BOB is defective, you can, in accordance with the statutory provisions, in particular demand that the defect be remedied, reduce the price or terminate the contract, and claim damages or reimbursement of futile expenses. We provide updates that keep BOB in conformity with the contract — including security updates — for the entire term of your contract (Section 327f BGB). The following paragraphs do not restrict these rights.

We operate BOB with the care of a prudent businessperson but do not owe any particular availability. Maintenance work, further development and disruptions at upstream providers (in particular hosting, payment processing, email delivery) may lead to temporary restrictions. Where possible, we schedule planned maintenance windows at times of low usage and announce them if they are expected to last longer than one hour.

For periods in which BOB cannot be used to a significant extent and for several days for reasons for which we are responsible, the fee is reduced proportionately. Clause 12 applies to damages.

12. Liability

We are liable without limitation for intent and gross negligence, for injury to life, body or health, under the provisions of the German Product Liability Act and to the extent of any guarantee we have assumed.

In the event of a slightly negligent breach of a material contractual obligation — that is, an obligation whose fulfilment makes the proper performance of the contract possible in the first place and on whose observance you may regularly rely — our liability is limited in amount to the damage that was foreseeable and typical for the contract at the time the contract was concluded.

Otherwise, our liability is excluded. This applies in particular to damage resulting from your having made decisions on payments, contracts, notices of defects, deadlines or tax returns on the basis of the information displayed in BOB (clauses 4 and 5), and to loss of profit and indirect damage.

For the loss of data, we are only liable to the extent that the damage would also have occurred if you had backed up your data properly and regularly. BOB provides you with export functions at all times; use them regularly.

The above limitations of liability also apply to our legal representatives and vicarious agents.

13. Indemnification

If you post content that infringes the rights of third parties, you indemnify us against resulting claims by third parties insofar as you are responsible for the infringement. This includes the reasonable costs of a necessary legal defence. We will inform you of any such claims without undue delay and consult with you before any acknowledgement or settlement.

14. Data protection

How we process personal data is set out in the privacy policy. It is not part of these GTC; it fulfils our statutory information obligations.

15. Changes to these GTC

We may amend these GTC if this is necessary to adapt them to changes in the law, supreme court case law, technical developments or a changed scope of functions and does not unreasonably disadvantage you. We will notify you of changes in text form at least six weeks before they take effect.

If you do not object by the time they take effect, the changes are deemed accepted; we will point out this effect and your right to object separately in the notification. If you object, we may terminate the contract effective at the time the changes take effect. Changes to the main performance obligations or to prices are not possible in this way; clause 6 applies to them.

16. End of contract, export and deletion

Exports of your data (CSV, XLSX, PDF) are available to you throughout the entire term of the contract, in the Free plan to the extent provided there. After a paid plan ends, your account continues within the scope of Free; your data is not deleted, paid functions are suspended.

If you delete your account, your projects, documents and files are removed immediately and irretrievably. Projects in which other owners are registered remain available to them; only your membership ends there. Back up everything you want to keep beforehand. Statutory retention obligations remain unaffected.

17. Final provisions

The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods. If your habitual residence is in another member state of the European Union, the mandatory consumer protection provisions of that state also remain unaffected.

We are neither willing nor obliged to take part in dispute resolution proceedings before a consumer arbitration board.

Should any provision of these GTC be or become invalid, the validity of the remaining provisions remains unaffected. The statutory provision takes the place of the invalid provision.
