- ◆a contract, order confirmation, or digital offer is accepted;

Heldwerk may additionally refer the client to these terms in offers, order confirmations, or invoices.
04
Order of precedence
In case of conflict, the following order applies:
- individually signed contract or individual written agreement;
- accepted offer or order confirmation;
- any annexes, scope descriptions, project plans, or service-level agreements;
- any data processing agreement or data protection annexes;
- these terms.
Individual agreements take precedence over these terms.
05
Scope of services
The concrete scope of services results from the respective offer, order confirmation,
scope description, or selected package.
Services not expressly agreed are not owed. This includes in particular:
- ◆additional pages, functions, interfaces, or design variants;
- ◆ongoing content maintenance, unless maintenance was agreed;
- ◆hosting, domains, licenses, or third-party costs, unless explicitly included;
- ◆legal, tax, medical, or industry-specific advice;
- ◆success guarantees for rankings, revenue, leads, AI citations, or conversion rates;
- ◆continuous monitoring of third-party platforms, search engines, or AI systems without a corresponding mandate.
Heldwerk may choose technical solutions, tools, frameworks, hosting models, and third-party
providers at its professional discretion, unless a specific solution has been bindingly agreed.
06
Offers and prices
Heldwerk offers are valid for 30 days unless otherwise stated.
All prices are in Swiss Francs (CHF). VAT is only itemized and charged if Heldwerk is or becomes
subject to mandatory VAT registration.
Third-party costs such as hosting, domains, font licenses, plugins, stock material, API fees,
AI usage, email services, payment providers, external software, or other external services
are only included if listed in the offer.
Heldwerk may pass on necessary third-party costs to the client after prior information.
07
Payment terms
Unless otherwise agreed, the following payment terms apply:
- ◆One-off projects: 50% on contract signing, 50% before go-live, handover, or completion.
- ◆Smaller jobs: payable on invoice.
- ◆Mandates, maintenance, support, and subscriptions: monthly in advance.
- ◆Workshops and audits: payable before delivery or as per offer.
- ◆Third-party costs: payable immediately or per invoice.
Invoices are payable within 10 days of invoice date without deduction, unless a different
payment term is specified on the invoice.
In case of payment default, Heldwerk may:
- ◆charge reminder fees and statutory default interest;
- ◆pause ongoing work;
- ◆temporarily block access, support, maintenance, or software services;
- ◆withhold further services until full payment.
The client remains liable for payment of amounts already owed even during a block.
08
Client cooperation duties
The client provides Heldwerk in a timely manner with all information, content, data, access,
decisions, and approvals necessary for service delivery.
Depending on the project, this includes in particular:
- ◆texts, images, logos, brand materials, and design guidelines;
- ◆access credentials for hosting, domains, CMS, analytics tools, email systems, or third-party platforms;
- ◆contact persons with decision-making authority;
- ◆feedback, corrections, and approvals within agreed deadlines;
- ◆legal mandatory information such as imprint, privacy information, terms, industry notices, or licenses;
- ◆professional information on which content, chatbots, AI systems, or automation are built.
If a project is delayed due to missing cooperation, deadlines are extended appropriately.
Additional effort may be billed at the agreed hourly rate or, if no rate was agreed,
at CHF 180 per hour.
09
Content and legal responsibility of the client
The client is responsible that content, data, and materials provided may be legally used.
This concerns in particular:
- ◆texts, images, videos, graphics, logos, and trademarks;
- ◆personal data;
- ◆customer data, health data, financial data, or other particularly sensitive information;
- ◆statements about products, prices, healing effects, guarantees, licenses, or qualifications;
- ◆industry-specific information and disclosure obligations.
Heldwerk checks content only for technical, linguistic, or design plausibility, not for
final legal admissibility. Legal review by a professional remains the client's responsibility.
The client indemnifies Heldwerk from third-party claims arising from unlawful, faulty, or
improperly provided content.
10
Project flow, feedback, and approvals
For projects with concept, design, development, or implementation phases, Heldwerk provides
interim results for client review.
Feedback must be clear, consolidated, and within the agreed or reasonable deadline.
Contradictory, late, or repeatedly changed feedback may lead to additional effort and
schedule shifts.
Services are considered approved when:
- ◆the client expressly agrees;
- ◆the service goes into production;
- ◆the client uses the service;
- ◆no material defects are reported within 10 working days of delivery.
Minor errors or optimizations that don't materially impair production use do not justify
refusal of full acceptance.
11
Changes, additional work, and scope creep
Changes or extensions after offer acceptance are possible if Heldwerk can implement them
professionally and within schedule.
Additional effort arises in particular with:
- ◆new functions or pages;
- ◆changed requirements;
- ◆additional design variants;
- ◆subsequent structural changes;
- ◆additional interfaces;
- ◆changed third-party specifications;
- ◆late-delivered content;
- ◆repeated correction rounds outside the agreed scope.
Heldwerk informs the client in advance about relevant extra costs where possible. For minor
extra work up to CHF 300, Heldwerk may bill without separate approval if the extra work is
necessary for sensible project completion.
12
Deadlines and dates
Deadlines and dates are only binding when expressly designated in writing as binding.
Deadlines are extended appropriately when:
- ◆the client doesn't fulfill cooperation duties on time;
- ◆third parties (hosting, domain registrars, payment providers, AI providers, other external services) cause delays;
- ◆technical problems arise outside Heldwerk's control;
- ◆force majeure or unforeseeable events occur;
- ◆project scope is changed.
Heldwerk is not liable for delays caused by missing cooperation, third parties, or circumstances
outside its control.
13
Web design, web development, and web applications
Heldwerk creates websites and web applications per the agreed scope.
A website or web application is considered complete when it fulfills the agreed core functions
and has no material defects preventing production use.
Without express agreement, the following are not owed:
- ◆unlimited correction rounds;
- ◆pixel-perfect identity across all browsers, devices, and operating systems;
- ◆permanent compatibility with future browser, CMS, framework, or third-party versions;
- ◆content in multiple languages;
- ◆accessibility per a specific standard;
- ◆legal review;
- ◆ongoing maintenance or security monitoring.
Heldwerk ensures clean technical implementation, performance, mobile usability, and an
appropriate base structure for search engines and AI systems, insofar as this is part of the project.
14
SEO, GEO, and visibility services
Heldwerk may provide services in search engine optimization, local visibility, technical SEO,
content structure, structured data, and optimization for AI search and answer systems.
The client acknowledges that rankings, visibility, AI citations, traffic, leads, revenue gains,
and similar results depend on many factors, particularly competition, market, existing content,
domain history, search and AI systems, user behavior, and ongoing maintenance.
Heldwerk owes diligent professional work, but no specific ranking position, no specific number
of leads, no inclusion in AI answers, and no commercial success.
15
AI consulting, AI training, and implementation
Heldwerk provides AI consulting, audits, workshops, training, and implementation services
to the best of its knowledge with a practice-oriented approach.
The client remains responsible for:
- ◆the decision which AI tools to deploy;
- ◆internal directives and policies;
- ◆review of industry-specific data protection, professional confidentiality, retention, and compliance obligations;
- ◆approval of AI processes for production;
- ◆control of AI-generated content before use.
Heldwerk gives no guarantee that AI systems will always respond error-free, completely,
non-discriminatorily, currently, or legally correctly.
AI results must be reviewed by professionally responsible persons before use towards customers,
patients, clients, authorities, or third parties.
16
HeldChat and chatbot solutions
HeldChat and comparable chatbot solutions serve to provide general information, answer routine
questions, pre-structure inquiries, and forward customers to suitable contact channels.
HeldChat does not replace personal consulting or any medical, legal, tax, financial, or other
professional case-specific advice.
The client is responsible for:
- ◆the accuracy and currency of provided knowledge sources;
- ◆approval of the content from which the chatbot derives answers;
- ◆regular review of chat logs, answers, and forwardings;
- ◆informing website visitors about the chatbot's use;
- ◆compliance with own data protection and disclosure obligations.
Heldwerk uses technical safeguards against incorrect, inappropriate, or unsupported answers.
However, complete prevention of erroneous answers cannot be guaranteed.
Heldwerk may restrict, pause, or adjust chatbot services if required for security, maintenance,
data protection, abuse prevention, or stability reasons.
17
Maintenance, support, and mandates
Maintenance, support, and mandate agreements apply in the agreed scope.
Unless otherwise agreed, mandates only cover services within the agreed time or scope.
Unused hours or services expire at the end of the respective billing period, unless transfer
is expressly agreed.
Response times are not guaranteed resolution times, unless a service-level agreement is
expressly agreed.
Support takes place during normal business hours on working days in the canton of Zürich,
unless otherwise agreed.
18
Third parties, licenses, and external services
Heldwerk may deploy or recommend third parties, particularly for:
- ◆hosting and domains;
- ◆CMS, databases, and cloud services;
- ◆analytics tools;
- ◆AI models and AI interfaces;
- ◆email delivery;
- ◆automation;
- ◆payment services;
- ◆maps, fonts, images, videos, or external APIs.
For third parties, their own contract, usage, data protection, and pricing terms apply.
Heldwerk is not liable for outages, price changes, function changes, data losses, blocks,
security incidents, or terms of third parties, insofar as Heldwerk is not itself at fault.
The client is obliged to use third-party accounts, licenses, and credentials lawfully and to
pay required fees.
19
Hosting and operation
Hosting and operation are only owed if expressly agreed.
If hosting is agreed, Heldwerk may use its own infrastructure or suitable third-party providers.
Data locations, security measures, and sub-processors result from the respective offer,
scope description, privacy policy, or data processing agreement.
Heldwerk pays attention to appropriate security and data protection compliance when selecting
hosting and cloud solutions. Exclusive data processing in Switzerland is only owed if expressly
agreed in writing.
Maintenance windows, security updates, technical adjustments, or short-term interruptions may
be necessary. Heldwerk strives to keep interruptions as short as possible.
20
Domains, access, and accounts
Domains, hosting accounts, CMS accounts, email accounts, analytics accounts, and other access
should where possible be registered in the client's name.
If accounts are temporarily managed by Heldwerk, this is done in a fiduciary capacity within
the scope of the order.
The client is co-responsible for secure passwords, two-factor authentication, and management
of own access.
After full payment and project completion, Heldwerk hands over project-related credentials,
insofar as technically possible, legally permitted, and contractually provided.
21
Usage rights and intellectual property
After full payment, the client receives the agreed usage rights to the work results individually
created for them.
This includes in particular individually created website structures, texts, designs,
configurations, and project-specific code, insofar as these were created by Heldwerk and
no third-party rights conflict.
Heldwerk retains rights to:
- ◆pre-existing tools, frameworks, libraries, components, and methods;
- ◆general concepts, know-how, templates, and reusable building blocks;
- ◆unpaid services;
- ◆drafts that were not finally approved or paid for.
Open-source components, third-party software, fonts, images, plugins, and other external
materials are subject to their respective license terms.
Transfer, reuse, modification, or commercial use outside the agreed purpose is only permitted
insofar as corresponding rights have been granted.
22
Reference mention
Heldwerk may name completed projects as references and use name, logo, screenshots, short
description, and link, unless the client objects in writing or legitimate confidentiality
interests stand in the way.
Confidential information, internal systems, credentials, non-public KPIs, or sensitive content
are not published without consent.
23
Confidentiality
Heldwerk and the client treat confidential information of the other party as confidential.
Confidential information is in particular trade secrets, credentials, internal documents,
customer data, technical information, unpublished concepts, prices, strategies, and personal data.
The confidentiality obligation also applies after contract end.
Confidential information does not include information that is already publicly known, lawfully
received from third parties, or independently developed.
24
Data protection
Heldwerk processes personal data within the applicable data protection laws, particularly the
Swiss Data Protection Act (DSG) and, where applicable, the EU General Data Protection Regulation (GDPR).
Details on data processing by Heldwerk result from the privacy policy at
heldwerk.ch/en/datenschutz.
The client remains responsible for the lawfulness of personal data they provide.
This applies in particular to:
- ◆contact forms;
- ◆newsletter integrations;
- ◆CRM integrations;
- ◆chatbots;
- ◆analytics tools;
- ◆customer data;
- ◆health data;
- ◆employee data;
- ◆applicant data;
- ◆particularly sensitive personal data.
Heldwerk takes appropriate technical and organizational measures to protect processed data.
25
Data processing
Insofar as Heldwerk processes personal data on behalf of the client, the parties act as
controller and processor within the meaning of applicable data protection law.
In such cases, a separate data processing agreement may be concluded. Such an agreement may
also form part of the offer, contract, or data protection annex.
Heldwerk processes order-related personal data only within the agreed purpose and the documented
instructions of the client, unless a legal obligation conflicts.
Heldwerk may use suitable sub-processors if necessary for service delivery and if appropriate
data protection and security measures are in place.
The client is responsible that no legal, contractual, or professional confidentiality
obligations conflict with data processing.
26
Data security
Heldwerk uses appropriate technical and organizational measures to protect data against
unauthorized access, loss, misuse, or alteration.
Depending on the project, these may include:
- ◆encrypted connections;
- ◆access restrictions;
- ◆role-based access;
- ◆password protection and two-factor authentication;
- ◆backups;
- ◆logging;
- ◆secure configurations;
- ◆regular updates;
- ◆limiting access to necessary persons and systems.
Absolute security cannot, however, be guaranteed. The client is obliged to also adequately
protect own systems, credentials, and internal processes.
27
Acceptance and defects
The client checks delivered services without delay after provision.
Defects must be reported to Heldwerk in writing within 10 working days, in a comprehensible manner.
A defect exists if the service materially deviates from the agreed scope.
No defect exists in particular with:
- ◆subjective dissatisfaction without deviation from the agreed service;
- ◆change requests after approval;
- ◆errors due to subsequent interventions by the client or third parties;
- ◆problems caused by third parties, browser updates, plugin updates, hosting changes, or external interfaces;
- ◆missing content or incorrect information from the client;
- ◆normal rendering differences between devices, browsers, and operating systems.
Heldwerk has the right to remedy legitimate defects by its choice or provide an appropriate
replacement solution.
28
Warranty
Heldwerk performs services diligently and professionally.
For individually developed websites, applications, or functions, Heldwerk warrants material
defects for 30 days after acceptance, unless another period is agreed.
For maintenance, support, consulting, SEO, GEO, AI, workshop, and mandate services, Heldwerk
owes diligent activity but no specific success.
Warranty is excluded for defects caused by:
- ◆interventions by the client or third parties;
- ◆improper use;
- ◆missing updates outside a maintenance contract;
- ◆third parties;
- ◆changed technical conditions;
- ◆incorrect or incomplete client data;
- ◆force majeure.
29
Liability
Heldwerk is liable for direct damages caused by intentional or grossly negligent behavior
of Heldwerk.
To the extent legally permissible, liability for slight negligence, indirect damages, consequential
damages, lost profits, data loss, reputation damages, revenue losses, business interruptions,
lost leads, ranking losses, or third-party claims is excluded.
To the extent legally permissible, Heldwerk's total liability is limited to the amount paid by
the client for the affected service in the three months prior to the damage event; for one-off
projects at most to the paid project price.
Mandatory statutory liability remains reserved.
The client is co-responsible for regular own backups, internal controls, legal reviews, and
organizational protective measures.
30
No legal, tax, medical, or financial advice
Heldwerk provides technical, design, organizational, and strategic services.
Heldwerk does not provide legal, tax, medical, financial, or other profession-specific
advice, unless expressly agreed and legally permitted.
Texts, structures, data protection or compliance notices, AI guidelines, terms drafts, process
documentation, or website content created by Heldwerk are working aids and must be reviewed
by qualified professionals where needed.
31
Termination
One-off projects can only be terminated for cause after order placement. Services already
performed, reserved capacities, third-party costs, and work in progress must be compensated.
Recurring mandates, maintenance contracts, and subscriptions can, unless otherwise agreed,
be terminated with 30 days' notice to the end of a month.
In case of serious breach of contract, payment default, abusive use, security risks, or
unlawful content, Heldwerk may immediately block services or terminate the contract for cause.
32
Consequences of contract termination
After contract end, Heldwerk provides the client on request with the agreed and paid project
data in a common format, insofar as technically possible, legally permitted, and contractually provided.
Not handed over: internal working files, calculations, reusable templates, unpaid drafts,
internal automation, internal prompts, trade secrets, or general know-how of Heldwerk.
Third-party access, domains, hosting accounts, and licenses are, where possible, transferred
or left to the client's own management, provided all open invoices are paid.
Heldwerk is not obliged to retain data indefinitely after contract end.
33
Blocking and abuse
Heldwerk may temporarily block services, access, chatbots, websites, or interfaces if:
- ◆unlawful content is processed or published;
- ◆security risks exist;
- ◆payment default exists;
- ◆systems are used abusively;
- ◆third parties require it;
- ◆excessive use endangers stability;
- ◆there's suspicion of spam, manipulation, attacks, or unauthorized use.
Heldwerk informs the client about the block and its reason where possible.
34
Force majeure
Heldwerk is not liable for delays or service failures due to force majeure or events outside
reasonable control.
These include in particular:
- ◆power outages;
- ◆internet outages;
- ◆outages of hosting, cloud, AI, API, or third-party providers;
- ◆cyber attacks;
- ◆regulatory measures;
- ◆natural events;
- ◆illness;
- ◆war, unrest, or comparable events;
- ◆disruptions at registry offices, payment providers, or communication services.
Deadlines are extended accordingly.
35
Changes to these terms
Heldwerk may adjust these terms if material reasons exist, particularly in case of changes
to the offering, technical implementation, legal situation, or used third parties.
For existing contracts, the version included at contract signing generally applies, unless
a new version is agreed.
For ongoing subscriptions, mandates, or maintenance contracts, Heldwerk may communicate
changed terms with reasonable notice. If the client doesn't object within 30 days, the changes
count as accepted. In case of material disadvantages, the client may terminate the affected
contract effective when the change takes effect.
36
Severability
Should any provision of these terms be or become wholly or partially ineffective, the
effectiveness of the remaining provisions remains unaffected.
The ineffective provision is replaced by an effective provision that comes as close as possible
to the economic purpose of the ineffective provision.
37
Applicable law and jurisdiction
Swiss substantive law applies, excluding conflict-of-laws provisions.
Place of jurisdiction is, to the extent legally permissible, Hinwil or the competent court
in the canton of Zürich.
Mandatory statutory places of jurisdiction, particularly for consumers, remain reserved.
38
Language
The German version of these terms is authoritative. Translations serve only for understanding.
