4. Description of Services

4.1 Decky AI is an AI-powered PowerPoint Add-in for:

Creating, structuring, and formatting presentation slides,
Generating content using artificial intelligence,
Processing user-provided content (text, images, slides),
Optional internet-based research, and
Searching and embedding images and icons from third-party databases.

4.2 No specific content-related, design-related, or commercial success is owed. The Service provides a tool; the suitability of the results is for the user to judge.

4.3 Beta and Preview Features. The provider may occasionally offer experimental or preview features (labeled as “Beta”, “Preview”, “Experimental”, or similar). These are provided without any warranty in their current state (“as is”). The provider may modify, restrict, or discontinue such features at any time and without prior notice. Liability for damages arising from the use of beta features is governed solely by Section 15.1.

5. Registration and User Account

5.1 Use of the Service requires a user account via Microsoft Entra External ID.

5.2 The user agrees to:

provide truthful and complete information during registration,
keep login credentials confidential and not share them with third parties,
notify the provider immediately of any unauthorized use of the account or other security breaches at hello@decky-ai.com.

5.3 Each user account is strictly personal. Sharing, selling, or joint use of account credentials is prohibited.

5.4 The user is responsible for all activities that occur under their account.

5.5 The provider is entitled to block or delete user accounts with immediate effect in the event of violations of these T&C. The provider may also delete inactive accounts after more than 12 months of inactivity, provided the user has been notified by email in advance.

6. Acceptable Use (Usage Policy)

6.1 The user may only use the Service in accordance with these T&C, applicable law, and the intended purpose.

6.2 In particular, it is prohibited to use the Service:

in a manner that violates applicable law, including data protection, copyright, competition, and export control law;
to develop products or services that compete with the Service, including training proprietary AI models using the Service’s outputs;
to decompile, reverse engineer, disassemble, or otherwise reduce the Service to a human-readable form, unless permitted by mandatory law;
for automated scraping, crawling, or other systematic extraction of data from the Service;
to generate content that is unlawful, offensive, discriminatory, glorifying violence, pornographic, extremist, or otherwise objectionable;
to generate content intended to mislead, deceive, or manipulate persons (disinformation);
to circumvent technical usage restrictions, security mechanisms, or quota limits;
to access the Service via automated means (bots, scripts) without prior written consent from the provider;
to process special categories of personal data within the meaning of Art. 9 GDPR (e.g. health data, biometric data, data relating to political opinions) via the Service;
to input content subject to a statutory or contractual confidentiality obligation, if the user cannot take responsibility for further processing by third-party AI providers;
in a manner that impairs the operation of the Service or its use by other users (e.g. denial-of-service attacks, spam, introduction of malware);
to impersonate individuals or companies, assume false identities, or violate personality rights;
to provide legal, tax, financial, or medical advice to third parties based on AI outputs without independent professional review.

6.3 In the event of violations of the usage policy, the provider is entitled to temporarily or permanently block access to the Service, remove content, or terminate the user account. No claim to a refund of fees already paid exists in such cases.

7. Freemium Model, Subscriptions, and Payment

7.1 Freemium. Decky AI is offered as a freemium model. Free use (Basic Plan) includes a limited monthly quota.

7.2 Paid Subscriptions. Extended features and higher quotas are available through paid subscriptions (e.g. Pro Plan). The applicable prices, scope of services, and billing periods are presented transparently to the user prior to conclusion of the contract.

7.3 Automatic Renewal. Paid subscriptions automatically renew upon expiry of the respective term for another billing period of the same duration (typically one month), unless the user cancels no later than 24 hours before the end of the current billing period. The user is expressly informed of the automatic renewal at the time of concluding the contract.

7.4 Payment. Payment processing is handled by the payment service provider Stripe (Stripe Payments Europe, Ltd.). The Stripe Terms of Service also apply. The user ensures that the stored payment information is correct and up to date.

7.5 Price Changes. The provider is entitled to change subscription prices. Price changes will be communicated to the user at least 30 days before they take effect by email. If the user objects to the price change or cancels the subscription before the price change takes effect, the previous price shall apply until the end of the current billing period.

7.6 Refunds. Unless otherwise required by law (in particular the right of withdrawal under Section 19) or expressly provided for in these T&C, fees paid are non-refundable.

8. AI-Generated Content – No Substitute for Human Review

8.1 Content generated by Decky AI (hereinafter “Outputs”):

are generated automatically by artificial intelligence models,
may contain factual inaccuracies, even if they appear accurate due to their level of detail or phrasing,
may be incomplete, outdated, or contextually inappropriate,
may produce different results for identical inputs,
do not replace professional, legal, tax, financial, medical, or editorial review.

8.2 Use of the Service does not constitute advice – whether legal, commercial, tax, medical, or otherwise professional. The Service is an AI-powered productivity tool, not an advisory service.

8.3 The user is obligated to independently review all Outputs before using, sharing, publishing, or basing business decisions on them.

8.4 AI technology is constantly evolving. The quality, accuracy, and availability of Outputs may vary. The provider does not warrant consistent output quality.

9. Responsibility for Inputs and Content

9.1 The user is solely responsible for all content they enter into the Service (hereinafter “Inputs”), have generated, or further process.

9.2 This applies in particular to:

personal data of third parties,
company and customer data,
confidential, proprietary, or regulatorily protected information,
content subject to attorney-client privilege, a litigation hold, or a contractual non-disclosure agreement (NDA).

9.3 The user warrants that:
they are authorized to process such data,
no rights of third parties (in particular copyright, trademark, or personality rights) are infringed,
no statutory or contractual obligations are violated.

9.4 Note on Sensitive Data. The user is expressly informed that Inputs are transmitted to third-party AI providers (e.g. Azure OpenAI Service, Anthropic) for processing. Users should not enter trade secrets, highly confidential M&A data, special categories of personal data (Art. 9 GDPR), or data subject to regulatory retention obligations into the Service unless they have independently assessed and accepted the risks of AI processing.

9.5 The provider assumes no duty of review and no responsibility for the legality, accuracy, or appropriateness of content entered or processed by the user.

10. Data Processing and Data Processing Agreement

10.1 The processing of Inputs and Outputs takes place at the initiative and under the responsibility of the user. For purely consumer-side use of the Service, the provider does not act as a data processor within the meaning of Art. 28 GDPR.

10.2 For business customers (B2B) who use the Service to process personal data of third parties and for whom a data processing agreement pursuant to Art. 28 GDPR is required, the provider will make a data processing agreement (DPA) available upon request. Requests should be directed to hello@decky-ai.com.

10.3 Regardless of a DPA, the provider assumes no substantive responsibility for the content processed by the user.

11. Rights to Inputs and Outputs

11.1 Inputs. The user retains all existing rights to their Inputs. By using the Service, the user grants the provider a non-exclusive, worldwide, revocable right to process the Inputs for the purpose of providing, maintaining, and improving the Service.

11.2 Outputs. To the extent the provider holds any rights in the Outputs, the provider hereby assigns these rights to the user, subject to compliance with these T&C. The user is solely responsible for further use of the Outputs.

11.3 Similarity of Outputs. Due to the nature of AI models, similar or identical Outputs may be generated for different users. The provider therefore does not grant any exclusivity rights in Outputs.

11.4 Anonymized Data. The provider is entitled to use anonymized and aggregated usage data (which do not permit conclusions about individual users or their content) for improving the Service, statistical analysis, and further product development.

12. Intellectual Property and License

12.1 The provider grants the user a simple, non-transferable, non-sublicensable, revocable, and time-limited license to use the Service for the duration of the contract.

12.2 All rights to the software, the underlying AI models, prompts, algorithms, designs, the “Decky AI” brand, and all other intellectual property rights remain exclusively with the provider or the respective licensors.

12.3 The user may not use the “Decky AI” brand, logos, or other marks of the provider without the provider’s prior written consent.

13. Feedback

13.1 The provider welcomes feedback, suggestions for improvement, bug reports, and other input regarding the Service (hereinafter “Feedback”).

13.2 By submitting Feedback, the user grants the provider an irrevocable, royalty-free, worldwide, transferable, and sublicensable license to use, exploit, and implement the Feedback without restriction and without any obligation to pay compensation.

13.3 There is no obligation to submit Feedback.

14. Third-Party Services

14.1 The Service uses third-party services and content to provide its functionality, including:

AI Models: Azure OpenAI Service (Microsoft), Anthropic
Payment: Stripe

Observability: Azure Application Insights, LangSmith

14.2 These third-party services are subject to the respective terms of use and privacy policies of the third-party providers. The user acknowledges that use of the Service implies the applicability of these third-party terms.

14.3 The provider assumes no warranty, responsibility, or liability for the availability, accuracy, security, or performance of third-party services. Disruptions, changes, or discontinuations by third-party providers are not within the provider’s area of responsibility.

15. Liability

15.1 Unlimited Liability

The provider is liable without limitation:

in cases of intent and gross negligence,
for injury to life, body, or health,
under the provisions of the German Product Liability Act,
to the extent of a guarantee assumed by the provider.

15.2 Limited Liability

In cases of simple negligence, the provider is only liable for breaches of material contractual obligations (cardinal obligations) and limited to the typically foreseeable damage.

15.3 Liability Cap

Without prejudice to Section 15.1, the provider’s total liability – regardless of the legal basis (contract, tort, or otherwise) – is limited to the greater of the following amounts:

(a) the total fees actually paid by the user in the six months preceding the event giving rise to liability, or
(b) €100.

15.4 Exclusion of Liability

Liability is excluded for:

the factual accuracy, completeness, or suitability of AI Outputs,
economic, business, or strategic decisions made on the basis of Outputs,
presentations used by the user vis-à-vis third parties (customers, investors, boards),
damages resulting from the user’s processing of confidential, personal, or sensitive data,
lost profits, loss of revenue, data loss, business interruption, or indirect damages,
damages arising from the use of beta or preview features (Section 4.3).

15.5 Third-Party Providers as Beneficiaries

The exclusions and limitations of liability set out in Sections 14.3 and 15 apply equally in favor of the third-party providers listed in Section 14.1.

16. Indemnification

16.1 The user shall indemnify the provider, its legal representatives, employees, and agents against all claims by third parties asserted on account of:

unlawful or contractually non-compliant Inputs by the user,
data protection violations by the user,
violations of confidentiality obligations, copyright, or other proprietary rights,
violations of acceptable use (Section 6),
other breaches of duty by the user in connection with use of the Service.

16.2 The indemnification includes reimbursement of all costs incurred by the provider (including reasonable attorneys’ fees and court costs) as well as damages, fines, and administrative penalties resulting from the claims referred to in Section 16.1.

16.3 The provider will promptly inform the user of any claims asserted and give them the opportunity to participate in the defense.

17. Availability and Force Majeure

17.1 The provider strives for high availability of the Service but does not warrant uninterrupted or error-free use. The Service is provided in its current state (“as is”).

17.2 Maintenance work, technical disruptions, software updates, or external dependencies may lead to temporary limitations. The provider will announce planned maintenance in advance where possible.

17.3 Force Majeure. The provider is not liable for delays or failures in performance attributable to circumstances beyond its reasonable control. This includes in particular:

natural disasters, pandemics, epidemics,
war, terrorism, civil unrest, sanctions, embargoes,
outages or performance limitations of third-party AI providers (e.g. Azure OpenAI, Anthropic),
failures of internet or telecommunications infrastructure,
governmental orders, changes in law, regulatory interventions,
cyberattacks, DDoS attacks, or other security incidents.

17.4 For the duration of a force majeure event, the affected performance obligations are suspended. The provider will promptly inform the user and take reasonable steps to mitigate the impact.

18. Term and Termination

18.1 Free use (Basic Plan) may be terminated at any time by deleting the user account.

18.2 Paid subscriptions apply for the agreed term and renew automatically in accordance with Section 7.3. The user may cancel the subscription no later than 24 hours before the end of the current billing period. Cancellation may be effected at any time via the customer portal or by email to hello@decky-ai.com.

18.3 Upon cancellation of a subscription, access to the Service remains active until the end of the paid billing period. Fees already paid will not be refunded unless otherwise required by law.

18.4 The right of either party to terminate for cause without notice remains unaffected. Good cause for the provider exists in particular in the event of:

serious or repeated violations of Section 6 (Usage Policy),
payment default despite a reminder,
use of the Service for criminal activities.

18.5 Upon termination of the contractual relationship, all usage rights granted to the user expire. The provider is entitled to delete user data after expiry of statutory retention periods. Sections 8, 9, 11, 13, 15, 16, and 22 survive termination of the contract.

19. Right of Withdrawal (Consumers Only)

19.1 Right of Withdrawal

You have the right to withdraw from this contract within fourteen days without giving any reason.

The withdrawal period is fourteen days from the date of conclusion of the contract.

To exercise your right of withdrawal, you must inform us:

Maven Labs UG (haftungsbeschränkt) Baaderstraße 17, 80469 Munich Email: hello@decky-ai.com

by means of a clear declaration (e.g. a letter sent by post or an email) of your decision to withdraw from this contract. You may use the attached model withdrawal form (Annex 1), although this is not mandatory.

To meet the withdrawal deadline, it is sufficient that you send your communication concerning the exercise of the right of withdrawal before the withdrawal period has expired.

19.2 Consequences of Withdrawal

If you withdraw from this contract, we will reimburse you all payments we have received from you, without undue delay and no later than fourteen days from the day on which we receive notification of your withdrawal from this contract. We will use the same means of payment as you used for the initial transaction, unless expressly agreed otherwise with you; in no event will you be charged for this reimbursement.

If you requested that the services begin during the withdrawal period, you shall pay us a reasonable amount corresponding to the proportion of the services already provided up to the point at which you inform us of the exercise of the right of withdrawal, in comparison with the total scope of the services provided for in the contract.

19.3 Early Expiry of the Right of Withdrawal

The right of withdrawal expires in the case of a contract for the supply of digital content not supplied on a tangible medium if the provider has begun to perform the contract after the consumer:

has expressly consented to the provider beginning performance of the contract before the expiry of the withdrawal period, and
has confirmed their knowledge that their right of withdrawal is lost upon the commencement of performance of the contract.

20. Amendments to the Service and These T&C

20.1 Amendments to the Service

The provider may further develop the Service, add, modify, or remove features. In the event of material changes that significantly restrict the scope of functionality or availability of the Service, the provider will notify the user by email at least 30 days in advance.

In urgent cases (e.g. security incidents, governmental orders, combating misuse), the notice period may be waived.

20.2 Amendments to These T&C

The provider is entitled to amend these T&C, provided this is:

required for legal, regulatory, or security-related reasons,
necessary to reflect new features or services, or
does not unreasonably disadvantage the user.

Material amendments will be communicated to the user at least 30 days before they take effect by email. The amendments will be deemed approved if the user does not object within this period. The user will be informed of their right to object and the legal consequences of silence in the amendment notice.

20.3 Right to Terminate upon Amendments

If the user does not agree to material amendments to the Service or the T&C, they may terminate the contractual relationship before the amendments take effect. For paid subscriptions, the provider will in such case pro-rata refund any fees already paid for the remaining period after the termination takes effect.

21. Data Portability

21.1 The user may at any time request the release of their exportable data stored in the Service in a common, machine-readable format. Requests should be directed to hello@decky-ai.com.

21.2 The provider will comply with the request within 30 days of receipt of the request, provided no technical or legal obstacles exist.

22. Assignment and Transfer

22.1 The user may not assign or transfer rights and obligations arising from this contractual relationship to third parties without the prior written consent of the provider.

22.2 The provider is entitled to transfer rights and obligations arising from this contractual relationship in whole or in part to third parties, in particular in the context of a corporate restructuring, merger, or sale of the business. The user will be informed of such transfer.

23. Governing Law

The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods (CISG).

For consumers, this choice of law applies only to the extent that it does not deprive them of the protection afforded by mandatory consumer protection provisions of the law of their country of habitual residence.

24. Jurisdiction

For merchants and companies, the exclusive place of jurisdiction is Munich.

For consumers, place of jurisdiction is determined by the applicable statutory provisions.

25. Online Dispute Resolution (ODR)

25.1 The European Commission provides a platform for online dispute resolution (ODR), which is accessible at the following link: https://ec.europa.eu/consumers/odr

25.2 Our email address is: hello@decky-ai.com

25.3 The provider is neither obligated nor willing to participate in dispute resolution proceedings before a consumer arbitration board.

26. Final Provisions

26.1 Severability Clause. Should individual provisions of these T&C be or become wholly or partially invalid or unenforceable, the validity of the remaining provisions shall remain unaffected. The invalid or unenforceable provision shall be replaced by a provision that most closely approximates the economic purpose of the invalid provision.

26.2 No Waiver. The failure by the provider to enforce any right or provision of these T&C shall not constitute a waiver of that right or provision.

26.3 Written Form. Amendments and supplements to these T&C require text form (Section 126b BGB), unless expressly otherwise provided in these T&C (cf. Section 20.2).

26.4 Entire Agreement. These T&C, together with the Privacy Policy and, where applicable, a concluded DPA, constitute the entire agreement between the parties regarding the subject matter of the contract and supersede all prior oral or written agreements.
