Contact

Via the support function and the electronic contact options given in the app’s imprint

These General Terms and Conditions apply to all free and paid functions of Brief Monster unless something different is agreed for the respective offer. A consumer is any natural person who concludes the contract predominantly for private purposes.

If you purchase via Apple, Google or another app store, its terms apply in addition for the store account, payment processing, renewal and the way to cancel. For the digital service owed by Brief Monster, these terms take precedence unless mandatory law or mandatory store rules conflict with them.

2 Scope of services

Brief Monster provides automated assistance functions. Depending on the function chosen, the app can in particular:

• capture and summarise letters, official notices, bills and other documents and explain them in plain language;
• check bills automatically for calculation errors, missing mandatory information, duplicate items, conspicuous amounts and formal or billing-related inconsistencies;
• for doctors’ and dentists’ bills, examine among other things fee codes, multipliers, justifications and arithmetic relationships for anomalies;
• show general information on possible next steps or relevant rules;
• create editable drafts for queries, complaints, objections or appeals (Widersprüche); and
• save deadlines confirmed by the user as reminders.

What is owed is the provision of the technical assistance functions described, not a particular legal, medical, economic, tax or official outcome. The specific range of functions follows from the current product description and the chosen plan.

3 Use of artificial intelligence and limits of the results

Brief Monster uses text recognition, rule-based methods and generative artificial intelligence. The user communicates with an AI system and, as a rule, not with a human. Individual results are not checked by a human beforehand. The generative language models come from OpenAI and are accessed through the intermediary platform OpenRouter; messages and documents are only transmitted for this with the consent the user expressly gives at registration. Details are in the privacy policy.

AI output is generated probabilistically. Despite careful development, it may be incomplete, misleading, outdated or factually wrong. This can affect in particular names, amounts, fee codes, multipliers, deadlines, references to laws, calculations and the assignment of document content. Source references or a confident style of language do not prove correctness.

The user must check important information and results against the original document. Where rights may be lost, in ongoing court or administrative proceedings, enforcement, significant financial consequences, complex tax questions or medical decisions, a qualified professional must be consulted without delay.

4 No legal, tax, financial or medical advice

Brief Monster does not replace individual advice or representation by lawyers, tax advisers, licensed financial advisers, doctors or other authorised persons. The app does not provide diagnoses, therapy or investment recommendations and does not represent the user towards authorities, courts, insurers, landlords, doctors or other third parties.

Information, check results and draft texts serve to inform and prepare the user’s own decisions. Brief Monster does not give a binding legal opinion and does not decide whether a claim, bill, treatment or official measure is lawful or medically necessary. The user decides for themselves whether and in what form to use a result.

5 Bill checks and medical documents

The bill check is an automated plausibility and anomaly check. It can point out formal, arithmetic or billing-related anomalies, but confirms neither that a service was actually provided or medically necessary nor that a bill is fully correct in legal terms.

Doctors’ bills and medical documents may contain health data. They are only processed after the user’s separate, explicit and revocable consent. This consent is not replaced by accepting these terms. Without consent the medical document workflow cannot be used; other functions are not affected.

6 Registration and use

Use is permitted to adults with full legal capacity. The user must provide correct information, keep access data secret and inform Brief Monster without delay if they suspect unauthorised use of their account.

The user account is personal. It may not be transferred or shared with third parties without the provider’s consent. The user is responsible for activities they culpably make possible via their account.

7 Conclusion of contract, prices and payment

Brief Monster may offer free functions, individual document checks, trial periods and monthly or yearly subscriptions. The scope of services, the final price including VAT, the billing period, the minimum term, renewal and the cancellation options are shown immediately before the order is completed.

For a purchase via an app store, the contract is concluded according to the ordering process shown there. A paid order is only placed via a button clearly labelled as an obligation to pay. Payment is processed by the provider named in the purchase process.

8 Term, cancellation and account deletion

A subscription runs for the period stated at purchase and only renews in the manner shown before the purchase. It can be cancelled via the account settings of the respective app store or via a cancellation function offered in the app, effective at the end of the current billing period.

Cancelling a subscription does not automatically delete the user account or stored documents. Account deletion can be requested separately in the app or via support. Statutory retention and documentation obligations remain unaffected.

9 Right of withdrawal and immediate start of performance

Consumers generally have a statutory right of withdrawal for distance contracts. The specific withdrawal information and the model withdrawal form are provided in durable form before the contract is concluded.

If the digital service is to begin before the withdrawal period has expired, the user is separately asked for the legally required express consent or express request and for the required acknowledgement. A waiver or expiry of the right of withdrawal is not declared merely by accepting these terms.

10 User obligations for documents and input

The user may only upload content they are entitled to have processed. This applies in particular to documents with data of other persons, health data, trade secrets, copyrighted content or confidential information. Data of third parties that is not needed should be blacked out before uploading.

Prohibited in particular are unlawful or fraudulent use, circumventing security measures, automated overloading, uploading malware, impersonation and attempts to obtain binding decisions or services reserved to certain professions.

11 Deadlines, drafts and sending

Deadline detection and reminders are auxiliary functions. Brief Monster does not guarantee that every deadline is detected, calculated correctly or reminded of in time. The user remains responsible for reading original documents, checking deadlines themselves and seeking professional advice immediately where necessary.

Letters generated by Brief Monster are editable drafts. The user must check recipients, names, facts, amounts, enclosures, claims and deadlines before use. Brief Monster does not send any letter without a separate and unambiguous action by the user and does not make any declaration on the user’s behalf towards third parties.

12 Rights to uploads and output

The user retains their rights to uploaded content. To perform the contract, they grant the provider a non-exclusive right, limited to this purpose, to technically reproduce, transmit, store and automatically process the content.

Insofar as rights arise in AI-generated output and belong to the provider, the user receives a simple right, unlimited in time and territory, to use the output for their own lawful private purposes. Rights of third parties, statutory texts and non-protectable content remain unaffected.

User documents, health data, chats and personal output are not used to train or generally improve AI models unless the user gives separate, voluntary and revocable consent for this.

13 Data protection, confidentiality and security

Personal data is processed in accordance with the separate privacy policy. As a rule, no blanket consent is required for the processing of normal documents that is necessary to perform the contract. For health data, separate express consent is obtained before processing.

multiangular UG (haftungsbeschränkt) has its registered office in the European Union. Primary document and application data is processed within the EU or the European Economic Area. Where platform providers acting as independent controllers, such as Apple or Google, process data, their privacy information applies in addition.

Documents and personal data are encrypted in transit and at rest in line with the state of the art. For the analysis requested by the user, document content has to be decrypted temporarily within a protected processing environment. There is therefore no end-to-end encryption when Brief Monster or a processor it uses analyses the content on the server.

14 Availability, maintenance and changes

The provider strives for high availability but does not owe uninterrupted use. Maintenance, security measures, disruptions of networks or third-party providers and events beyond reasonable control may temporarily limit availability.

Necessary security and functional updates are provided for the legally relevant period. The user is informed appropriately about significant changes that affect access or use. Mandatory rights regarding digital products remain unaffected.

15 Rights in the event of defects in digital products

The statutory rights for non-provision or defects apply to paid digital products. The user should report recognisable faults as comprehensibly as possible so that the provider can investigate them. Statutory claims are not excluded by a failure to report.

16 Liability

The provider is liable without limitation for damage resulting from injury to life, body or health that is based on an intentional or negligent breach of duty, and for other damage based on intent or gross negligence. Liability under the Product Liability Act (Produkthaftungsgesetz), from guarantees given, for fraudulent concealment of a defect and other mandatory statutory liability also remain unaffected.

In the event of a slightly negligent breach of an essential contractual obligation, liability is limited to the damage typical for the contract and foreseeable when the contract was concluded. Essential contractual obligations are those whose fulfilment makes the proper performance of the contract possible in the first place and on whose observance the user may regularly rely.

Otherwise, liability for damage caused by slight negligence is excluded. The above limitations also apply in favour of the provider’s legal representatives, employees and vicarious agents. Statutory claims for non-provision or defects of digital products are not restricted impermissibly.

17 Suspension and extraordinary termination

The provider may temporarily block access or terminate the contract for good cause if the user uses the service in a seriously unlawful or abusive manner, circumvents security measures or infringes the rights of third parties. Where reasonable, the user is informed beforehand and given the opportunity to remedy the situation. Fees already paid are only retained to the extent legally permissible.

18 Consumer dispute resolution

multiangular UG (haftungsbeschränkt) is neither willing nor obliged to take part in dispute resolution proceedings before a consumer arbitration board.

19 Applicable law and place of jurisdiction

German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. For consumers, this choice of law only applies insofar as it does not deprive them of the protection of mandatory provisions of the country of their habitual residence.

The statutory places of jurisdiction apply to consumers. An exclusive place of jurisdiction at the provider’s registered office is only agreed with merchants, legal entities under public law or special funds under public law.

20 Final provisions

Should individual provisions be or become invalid, the remaining provisions remain valid. The statutory provision takes the place of the invalid provision. Individual agreements remain possible and take precedence over these terms.
