4. Description of Services

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

using content provided by the user (text, images, slides),
optional internet-based research, and
searching for and inserting images and icons from third-party databases.

4.2 No specific substantive, creative, or commercial outcome is owed. The Service provides a tool; the suitability of the results is for the user to assess.

4.3 Beta and preview features. The provider may occasionally offer experimental or preview features (labeled “Beta,” “Preview,” “Experimental,” or similar). These are provided “as is.” The provider may modify, restrict, or discontinue such features at any time without notice. The provider shall only be liable for damages arising from the use of beta features in accordance with § 15.1. Mandatory statutory warranty rights of consumers remain unaffected (§ 17.5).

5. Registration and User Account

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

5.2 The user undertakes to:

provide truthful and complete information upon registration,
keep access credentials confidential and not share them with third parties,
promptly inform the provider 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 jointly using 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 suspend or delete user accounts with immediate effect in case of violations of these Terms. The provider may also delete inactive accounts after more than 12 months of inactivity, provided the user was previously notified by email.

6. Permitted Use (Usage Policy)

6.1 The user may only use the Service in accordance with these Terms, applicable law, and its intended purpose.

6.2 In particular, use of the Service is prohibited:

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 human-readable form, unless permitted under 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 individuals (disinformation);
to circumvent technical usage restrictions, security mechanisms, or quota limits;
to access the Service via automated means (bots, scripts) without the provider’s prior written consent;
to process special categories of personal data within the meaning of Art. 9 GDPR (e.g., health data, biometric data, data on political opinions) under the Standard/B2C plan; under the Enterprise plan, such processing is only permitted where the user has its own legal basis under Art. 9 GDPR, within the scope of the separate Data Processing Agreement (DPA), and limited to what is necessary;
to input content that is subject to a statutory or contractual duty of confidentiality (e.g., NDA-bound content, trade secrets within the meaning of the German Trade Secrets Act (GeschGehG)), unless the user can independently justify further processing by third-party AI providers; under the Enterprise plan, this restriction does not apply to content whose processing is limited, under the separate DPA, to EU-hosted infrastructure without AI model training, provided the user holds its own authorization to share the content under the applicable confidentiality relationship;
in a manner that impairs the operation of the Service or its use by other users (e.g., denial-of-service, spam, introduction of malware);
to impersonate persons or companies, to feign false identities, or to infringe 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 suspend access to the Service, remove content, or terminate the user account. In such cases, there is no entitlement to a refund of fees already paid.

7. Freemium Model, Subscriptions, and Payment

7.1 Freemium. Decky AI is offered on a freemium basis. Free use (Basic plan) includes a limited monthly quota.

7.2 Paid subscriptions. Advanced features and higher quotas are available through paid subscriptions (e.g., Pro plan). The applicable prices, scope of services, and billing periods will be presented to the user transparently before the contract is concluded.

7.3 Automatic renewal.

a) Consumers (B2C). Monthly subscriptions automatically renew for one additional month after the end of each month unless the user cancels. Subscriptions with a fixed initial term of more than one month (in particular annual subscriptions) automatically convert to an indefinite term after the initial term expires; in this case, the user may cancel at any time with one month’s notice. From the time of renewal, billing occurs monthly at the then-current monthly price of the selected plan. The user is expressly informed of automatic renewal at the time the contract is concluded.

b) Businesses (B2B). Paid subscriptions automatically renew for a further billing period of equal duration after the respective term expires, unless the user cancels at least 24 hours before the end of the current billing period.

7.4 Payment. Payment processing is handled by the payment service provider Stripe (Stripe Payments Europe, Ltd.). Stripe’s terms of use additionally apply. The user shall ensure that the payment information on file is accurate and up to date.

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

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

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

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

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

8.2 Use of the Service does not constitute advice – whether legal, economic, 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 under continuous development. The quality, accuracy, and availability of Outputs may vary. The provider does not guarantee consistent output quality.

8.5 AI labeling and transparency (Art. 50 AI Act). Synthetic content generated by Decky AI (in particular AI-generated images) is labeled as artificially generated or manipulated in machine-readable form to the extent it falls within the substantive scope of Art. 50(2) of the AI Act. The user undertakes not to remove or alter such labels, watermarks, or metadata. Where the user publishes or otherwise uses AI-generated Outputs vis-à-vis third parties, the user is solely responsible for compliance with any applicable transparency and labeling obligations under Regulation (EU) 2024/1689 (the AI Act), in particular for disclosing the artificial origin of such content. Such disclosure obligation may not apply where the user subjects the relevant content to substantive human review prior to use and assumes editorial responsibility for it.

9. Responsibility for Inputs and Content

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

9.2 This applies in particular to:

personal data of third parties,
corporate and customer data,
confidential, secret, 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 third-party rights (in particular copyright, trademark, or personality rights) are infringed,
no statutory or contractual obligations are violated.

9.4 Notice regarding sensitive data. The user is expressly informed that Inputs may be transmitted to third-party AI providers for processing. Special categories of personal data (Art. 9 GDPR) are not permitted under the Standard/B2C plan. Enterprise customers may only process such data if they do so within the scope of the separate DPA, have a legal basis under Art. 9 GDPR, and limit processing to what is necessary. Trade secrets, highly confidential M&A data, and data subject to regulatory retention obligations may only be transmitted after the user’s own risk and permissibility assessment.

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

10. Data Processing and Processing on Behalf

10.1 The processing of Inputs and Outputs occurs at the initiative and responsibility of the user. For the purely consumer-facing use of the Service, the provider does not act as a 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 relationship under 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 Irrespective 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 and maintaining the Service; any improvement of the Service based on such Inputs takes place only in accordance with the Privacy Policy or, under the Enterprise plan, the Data Processing Agreement (DPA).

11.2 Outputs. To the extent the provider holds any rights in the Outputs, the provider hereby assigns such rights to the user, subject to compliance with these Terms. The user is solely responsible for any 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 to Outputs.

11.4 Anonymized data. The provider is entitled to use anonymized and aggregated usage data (that does not permit conclusions about individual users or their content) to improve the Service, for statistical analysis, and for the further development of its products.

12. Intellectual Property and Usage Rights

12.1 The provider grants the user a simple, non-transferable, non-sublicensable, revocable right of use, limited to the term of the contract, to the Service.

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

12.3 The user may not use the “Decky AI” trademark, logos, or other identifiers 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 right of use to use, exploit, and implement the Feedback without any 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: Amazon Bedrock (AWS), Azure OpenAI Service (Microsoft), Anthropic (Standard/B2C plan)
Payment: Stripe
Authentication: Microsoft Entra External ID
Search: Linkup
Media: Unsplash, Pixabay
Observability: Azure Application Insights, LangSmith

14.2 To the extent third-party terms apply directly to the user for individual features, they will be separately disclosed prior to use of the relevant feature. Otherwise, the provider will ensure the necessary agreements with the third-party providers used to render the Service.

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 the responsibility of the provider. The provider’s statutory liability, in particular under §§ 15.1 and 15.2, as well as mandatory consumer rights, remain unaffected.

15. Liability

15.1 Unlimited Liability

The provider is liable without limitation:

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

15.2 Limited Liability

In the case of ordinary negligence, the provider shall only be liable for breach of material contractual obligations (cardinal obligations), i.e., obligations whose fulfillment is essential for the proper performance of the contract in the first place and on whose compliance the user may regularly rely, and such liability shall be limited to the typically foreseeable damage at the time the contract was concluded.

15.3 Liability Cap

Notwithstanding § 15.1, the provider’s liability for damages arising from ordinary negligence in connection with breach of material contractual obligations (§ 15.2) – regardless of the legal basis of the claim (contract, tort, or otherwise) – is limited to the typically foreseeable damage at the time the contract was concluded.

An additional cap on the amount, limited to three times the fees paid by the user in the twelve months preceding the event giving rise to liability, shall apply only insofar as it does not fall below the typically foreseeable, contract-typical damage.

15.4 Exclusion of Liability

The limitations of liability under this § 15, as well as the exclusions of liability below, do not apply in the cases set out in § 15.1 and not in the case of breach of material contractual obligations within the meaning of § 15.2. Otherwise, liability is excluded for:

the accuracy, completeness, or suitability of AI Outputs,
economic, business, or strategic decisions made based on Outputs,
presentations that the user uses vis-à-vis third parties (customers, investors, boards),
damages insofar as they were caused by unlawful inputs, data, or instructions of the user, or by unlawful use of the Service,
lost profits, loss of revenue, business interruption, or indirect damages,
damages arising from the use of beta or preview features (§ 4.3).

For the loss of data, the provider shall only be liable within the scope of §§ 15.1 through 15.3 to the extent that such loss would have occurred even if the user had performed proper and regular data backups.

15.5 Third Parties as Beneficiaries

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

15.6 Limitation Period

For users who are consumers within the meaning of § 13 BGB, only the statutory limitation period applies; no shortening under this § 15.6 takes place for such users.

For users who are not consumers, claims for damages against the provider that are based neither on intent nor gross negligence and do not concern a breach of material contractual obligations (cardinal obligations, § 15.2) shall become time-barred within one year from the statutory commencement of the limitation period under § 199 BGB, by way of derogation from the standard statutory limitation period; § 202(1) BGB remains unaffected. Claims based on intent, gross negligence, or breach of material contractual obligations, as well as claims arising from injury to life, body, or health and claims under the German Product Liability Act, remain in every case subject exclusively to the statutory limitation period.

16. Indemnification

16.1 The user shall indemnify and hold harmless the provider, its legal representatives, employees, and agents from any third-party claims that are based on a breach of duty attributable to the user and asserted due to:

unlawful or contract-violating inputs by the user,
data protection violations by the user,
infringements of confidentiality, copyright, or other protective rights,
violations of permitted use (§ 6),
other breaches of duty by the user in connection with the use of the Service.

16.2 The indemnification includes reimbursement of all costs incurred by the provider (including reasonable legal and court costs) as well as damages, fines, and administrative penalties resulting from the claims listed in § 16.1.

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

16.4 Vis-à-vis consumers, an indemnification or reimbursement obligation exists only to the extent the consumer is responsible for the underlying breach of duty. The statutory provisions otherwise remain unaffected.

17. Availability, Warranty, and Force Majeure

17.1 The provider strives for high availability of the Service but does not guarantee uninterrupted or error-free use. Vis-à-vis businesses (B2B), the Service is provided “as is.” Vis-à-vis consumers, provision “as is” does not apply; their mandatory statutory warranty rights and the update obligation under §§ 17.5 and 17.6 remain unaffected.

17.2 Maintenance work, technical disruptions, software updates, or external dependencies may lead to temporary restrictions. The provider will announce planned maintenance work 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, unrest, sanctions, embargoes,
outages or performance limitations of third-party AI providers (e.g., Amazon Bedrock, 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 as long as a force majeure event persists, the affected performance obligations shall be suspended. The provider will promptly inform the user and take reasonable measures to mitigate the effects.

17.5 Warranty rights (consumers). The statutory provisions on contracts for digital products (§§ 327 et seq. BGB) apply to consumers. The rights provided therein in the event of defects (in particular subsequent performance, price reduction, termination of the contract, and damages in accordance with § 15) are not excluded or restricted by these Terms.

17.6 Updates (consumers). The provider will provide consumers, during the relevant period, with such updates as are necessary to maintain the conformity of the Service (§ 327f BGB), and will inform consumers accordingly.

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 respective agreed term and renew automatically in accordance with § 7.3. Consumers whose subscription has converted to an indefinite term under § 7.3 a) may cancel at any time with one month’s notice; otherwise, cancellation is governed by § 7.3. Consumers additionally have access to an easily accessible cancellation button on the website in accordance with § 312k BGB. Cancellation may also be made 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 available 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 both parties to terminate for good cause remains unaffected. Good cause for the provider exists, in particular, in the case of:

serious or repeated violations of § 6 (usage policy),
default in payment 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 shall lapse. The user may retrieve exportable data or request its release within 30 days. After this period expires, the provider will automatically delete the user’s content from active systems, unless a statutory retention obligation prevents this; data in backups will be deleted according to the applicable backup cycles. §§ 8, 9, 11, 13, 15, 16, and 22 shall continue to apply beyond 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 day the contract was concluded.

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

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

by means of a clear statement (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 for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.

19.2 Consequences of Withdrawal

If you withdraw from this contract, we shall reimburse to you all payments received from you without undue delay and no later than fourteen days from the day on which we received notice of your withdrawal. For this reimbursement, we will use the same means of payment that you used for the original transaction, unless expressly agreed otherwise with you; in no case will you be charged any fees as a result of such reimbursement.

If you have requested that the service begin during the withdrawal period, you shall pay us a reasonable amount that corresponds to the proportion of services already provided until the time you inform us of the exercise of the right of withdrawal, in comparison to the total scope of services provided for in the contract.

19.3 Premature Expiry of the Right of Withdrawal

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

expressly agreed that the provider may begin performance of the contract before the withdrawal period has expired, and
confirmed their acknowledgment that, by giving that consent, they lose their right of withdrawal once performance of the contract has begun.

20. Changes to the Service and These Terms

20.1 Changes to the Service

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

In urgent cases (e.g., security incidents, governmental orders, abuse prevention), the advance notice period may be waived.

20.2 Changes to These Terms

The provider is entitled to amend these Terms, provided that such amendments:

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

Material changes will be communicated to the user by email at least 30 days before taking effect. The changes shall be deemed approved if the user does not object within this period. The user will be informed, as part of the change notice, of their right to object and the legal consequences of remaining silent.

The deemed-consent mechanism does not apply to changes to the principal contractual obligations, in particular price and scope of services, or to the relationship between performance and consideration. Price changes are governed exclusively by § 7.5. Changes that would materially shift the balance of the contract require the user’s express consent.

20.3 Right of Termination in the Event of Changes

If the user does not agree to material changes to the Service or these Terms, the user may terminate the contractual relationship before the changes take effect. For paid subscriptions, the provider will in this case refund, on a pro-rata basis, the fees already paid for the remaining period after the termination becomes effective.

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 such a request within 30 days of receipt, provided there are no technical or legal obstacles.

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 provider’s prior written consent.

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 connection with a corporate restructuring, merger, or sale of the business. The user will be informed accordingly.

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 country of their habitual residence.

24. Place of Jurisdiction

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

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

25. Consumer Dispute Resolution

25.1 The provider is neither willing nor obligated to participate in dispute resolution proceedings before a consumer arbitration board pursuant to § 36 of the German Act on Alternative Dispute Resolution in Consumer Matters (VSBG).

25.2 Contact for consumer-related matters: hello@decky-ai.com

26. Final Provisions

26.1 Severability clause. Should any individual provisions of these Terms be or become invalid or unenforceable, in whole or in part, the validity of the remaining provisions shall remain unaffected. The invalid or unenforceable provision shall be replaced by a provision that comes closest to the economic purpose of the invalid provision.

26.2 No waiver. The provider’s failure to enforce any right or provision of these Terms shall not constitute a waiver of that right or provision.

26.3 Form requirement. Amendments and supplements to these Terms require text form (§ 126b BGB), unless expressly provided otherwise in these Terms (see § 20.2).

26.4 Entire agreement. Together with any DPA that may be concluded, these Terms constitute the entire agreement between the parties regarding the subject matter of the contract and supersede all prior oral or written agreements. The Privacy Policy informs about the processing of personal data and is not part of the contractual performance obligations.

26.5 Contract language. The contract language is German. In the event of any discrepancy between this English translation and the German original, the German version shall prevail.
