Terms of Service

1. Scope and operator

These terms apply to the public website, access requests, access calls, beta onboarding, and the DeinHans bookkeeping product unless a signed customer agreement states otherwise. DeinHans is operated by Ariel Ben Shushan ERP Consultant, Frankfurter Allee 108a/Fabrikgebäude 2. Hof, 10247 Berlin, Germany.

2. Business customers only

The service is offered exclusively to entrepreneurs acting in the course of their commercial or independent professional activity, legal entities under public law, and special funds under public law. It is not offered to consumers.

• Access requests may require company name, business contact details, role or authority, business identifier where appropriate, and confirmation that the requested month relates to business activity.
• If we cannot verify the business context or authority, we may reject, defer, or limit access.
• Do not submit private household bookkeeping, consumer tax matters, or non-business financial documents.
• If a consumer-law route is ever offered, it will use separate pre-contract information, withdrawal, payment-button, cancellation, and gross-price rules.

3. Beta status and acceptance by us

DeinHans is currently offered in a limited B2B beta. Public assisted-access forms remain non-binding requests. An eligible business using the direct Engine route can create an account and start setup, but a customer relationship and trial begin only after identity confirmation, company and price confirmation, acceptance of the applicable terms, and successful workspace activation. We may reject, defer, limit, suspend, or stop beta access where needed for fit, capacity, compliance, security, misuse prevention, payment status, or product reliability.

4. Service scope

DeinHans provides software and workflow support for collecting sources, preparing non-binding bookkeeping evidence, extracting and matching information, surfacing exceptions, asking business-context questions, and handing prepared monthly work to the responsible reviewer, customer, accountant, or tax advisor. Specific scope depends on the accepted package and onboarding confirmation.

5. No tax, legal, or professional advice

DeinHans is a preparation and handoff product. System outputs, explanations, classifications, reports, exports, checks, and suggestions are not tax advice, legal advice, accounting advice, professional sign-off, filings, audit services, or a substitute for a licensed accountant, tax advisor, lawyer, or auditor. Professional judgment, filings, annual accounts, payroll, and special advisory remain with qualified professionals.

6. Access and accounts

You must provide accurate company, contact, billing, role, and bookkeeping setup information, keep credentials secure, and ensure that only authorized users access the product. You are responsible for activity under your account unless caused by our breach of security obligations.

7. Access request and onboarding rules

Submitting an assisted request, booking a call, or receiving a reply does not guarantee service acceptance. For the direct Engine route, acceptance occurs only when the eligible business confirms identity, company and exact price, accepts the applicable terms, and the workspace/trial activation succeeds. Other routes require our explicit confirmation or a separate agreement.

• We may require an access call, source review, identity/company check, package confirmation, and payment setup before granting access.
• We may refuse or postpone requests that are outside scope, legally sensitive, technically unsupported, high-risk, abusive, incomplete, or not suitable for beta capacity.
• Marketing claims, demo screenshots, and public examples describe intended workflows and may use synthetic data; they are not service guarantees.
• If we provide early access, it may be limited by users, organizations, sources, booking lines, months, integrations, countries, or review paths.

8. Customer responsibilities

You remain responsible for the information, documents, context, permissions, and decisions you provide or rely on.

• Provide complete, lawful, current, and truthful documents, bank exports, source data, business context, and billing information.
• Maintain a lawful basis and required notices for any personal data of employees, customers, suppliers, counterparties, or other third parties included in uploaded or connected materials.
• Answer open business questions promptly and accurately, including private/business use, missing proof, unusual transactions, contracts, refunds, payouts, and source gaps.
• Review outputs, tasks, reports, exports, classifications, VAT treatment, payment matching, and handover packages before relying on them.
• Keep original records and comply with statutory bookkeeping, tax, commercial, retention, and filing obligations that apply to you.
• Involve a licensed accountant, tax advisor, lawyer, or other qualified professional for professional judgment, filings, tax advice, legal advice, annual accounts, payroll, and special cases.

9. Accountant and partner work

When a licensed firm performs professional review, tax filings, annual accounts, or advisory work, that work is provided only under a separately accepted mandate. The firm remains responsible for professional judgment, filing, approval, fees, liability, and professional duties. DeinHans prepares bookkeeping records and routes open questions; DeinHans itself does not provide tax or legal advice.

10. Customer content and data protection

Customer data remains customer data. Public request forms are for fit information only and must not be used for invoices, receipts, bank exports, employee/customer data, or confidential bookkeeping documents. Before live uploads or connections are enabled, the applicable agreement must include or be accompanied by a data processing agreement where required. By uploading or connecting materials after onboarding, you grant us the rights needed to host, process, analyze, prepare, secure, support, and transmit that data for the service. During the active beta, a small group of specifically authorized DeinHans quality personnel may review uploaded documents and related processing results only where reasonably necessary to validate output quality, investigate an issue, or support you. This review is subject to need-to-know access controls and confidentiality obligations; relevant service actions may be recorded for security and audit purposes. Customer content is not used for unrelated advertising or to train general-purpose AI models. You must not upload unlawful content, malware, data you are not allowed to process, or material that infringes third-party rights.

11. Pricing, billing, taxes, and cancellation

The direct DeinHans Engine prices are shown net of VAT and are assigned from the confirmed legal form and annual net-revenue band. Eligible direct organizations receive a 30-day no-card trial after successful workspace activation. Stripe operates direct subscription billing and the Customer Portal. Professional-firm work, managed-client commercial arrangements, unsupported scope, and exceptional services remain separate and require an explicit order, mandate, or agreement.

• The DeinHans Engine costs EUR 29, EUR 49, or EUR 99 per month for an eligible business, depending on legal form and annual net revenue. Any professional mandate with an accounting firm is separate and begins only after the firm accepts it.
• A booking line, included line volume, overage rate, correction/retry treatment, supported entities, sources, integrations, months, users, third-party fees, professional-fee component, and invoicing flow must be defined in the accepted order, mandate, or onboarding confirmation.
• Not included unless agreed separately: annual accounts, tax returns, payroll, legal advice, tax advisory, historical cleanup, special advisory, unusual one-off cases, unsupported countries, or unsupported integrations.
• Fees are due according to the agreed billing terms. Late payment may lead to suspension or termination after appropriate notice where required.
• Cancellations, renewals, credits, refunds, export periods, and treatment of rejected or unsupported months are governed by the accepted order or separate agreement; statutory rights and mandatory law remain unaffected.

12. Availability and no guaranteed service level

We operate the beta service with reasonable care but do not guarantee uninterrupted availability, error-free operation, specific processing times, specific accountant outcomes, acceptance into beta, continued beta access, or compatibility with every bank, portal, accounting system, file, source, or customer case. Maintenance, provider incidents, security events, capacity limits, or integration outages may affect access.

13. Third-party services and integrations

The service may rely on providers such as Supabase, Vercel, Cloudflare, Cal.com, Notion, email providers, analytics providers, payment providers, banks, portals, and customer-selected tools. Third-party services may change, fail, restrict access, or require their own terms. We are not responsible for third-party services outside our control, but we will use reasonable efforts to keep critical workflows operational.

14. Automation and AI-assisted preparation

DeinHans may use deterministic automation and AI-assisted extraction, matching, classification, review preparation, and exception detection. These systems can be wrong, incomplete, delayed, or require human correction. They support preparation only and must be reviewed before use for accounting, tax, legal, reporting, or business decisions.

15. Intellectual property

The website, product, software, workflows, designs, text, templates, models, prompts, documentation, reports structure, and brand assets remain the property of DeinHans or its licensors. You may use the service only as permitted by these terms or a signed agreement. Customer data remains customer data.

16. Confidentiality and security

Each party shall protect non-public business, technical, financial, product, professional, and customer information received through the service, use it only for permitted purposes, disclose it only to authorized personnel, providers, advisors, or professional participants who need access, and continue confidentiality after termination. Compelled disclosure, security incidents, return, deletion, and professional-secrecy requirements may be further specified in the applicable agreement, DPA, or professional mandate.

17. Liability

Nothing in these terms limits liability for intent, gross negligence, injury to life, body, or health, mandatory statutory liability, or other liability that cannot legally be limited. Otherwise, to the extent permitted by law, liability is limited to foreseeable direct damages typical for this kind of beta software and workflow service. We are not liable for indirect losses, lost profits, lost savings, business interruption, missed deadlines, penalties, or damages caused by incorrect, incomplete, unlawful, or late customer information, unsupported use, third-party failures, or reliance on unreviewed outputs.

18. Suspension and termination

We may suspend or terminate access for misuse, security risk, non-payment, unlawful use, high-risk data, unsupported scope, beta capacity limits, provider restrictions, or material breach. The applicable order or agreement should state the effective date, payment consequences, export format and period, read-only period if any, deletion schedule, statutory retention override, backup timing, treatment of any professional mandate, and continuing confidentiality.

19. Changes to these terms or the service

We may update these terms for objective reasons such as product changes, beta scope, provider stack, security needs, business model, or legal requirements. Material adverse changes apply prospectively with reasonable notice where practical, and customers may terminate where the accepted agreement gives a termination right or mandatory law requires one. Continued use after the effective date may be treated as acceptance only where legally permitted.

20. Governing law and venue

German law applies, excluding conflict-of-law rules, unless mandatory consumer protection law requires another rule. If you are a merchant, legal entity under public law, or special fund under public law, the courts of Berlin, Germany, have jurisdiction to the extent permitted by law.
