  5. “Existing users” are users who have already used SiMaDoo before the introduction of General Terms and Conditions version 1.0.0 and have created or received data, events, community funds or group assignments.

  6. Differing conditions of a user only apply if the provider has expressly agreed to their validity.

2. Subject of SiMaDoo

  1. SiMaDoo is a digital application for organizing shared cash registers, events, deposits, expenses and internal billing within a group.

  2. SiMaDoo processes the data entered by users and uses it to create mathematical overviews. This can be shown in particular:

    • which inventory is mathematically in a common fund,
    • which people should still pay in,
    • which people should receive money back from the common fund,
    • how expenses were allocated within a group.

  3. SiMaDoo does not hold or manage money, does not carry out payment transactions and does not open bank or payment accounts. The application is not connected to the actual payment transactions between the parties involved, unless such a function is expressly offered in the future.

  4. SiMaDoo is not a banking, payment, tax, legal, financial, accounting or business consultancy. The results displayed do not replace a professional examination or legally required accounting.

  5. The current operation serves to introduce, test and further develop the application. Individual functions can be marked as test functions.

3. Consent and conclusion of the user agreement

  1. Before active use for the first time, the user must:

    • can view the full terms and conditions,
    • expressly agree to the terms and conditions and
    • confirm that he has reached the age of 18.

  2. The free usage contract is concluded when the user activates the two unchecked confirmations after being able to access the complete terms and conditions and then presses the consent button.

  3. First-time users cannot actively use SiMaDoo without consent. If you do not agree, the actual use of the app will be terminated. Access to terms and conditions, data protection declaration, legal notice and contact information remains possible.

  4. Existing users receive the consent dialog the first time they start after introducing the consent process.

  5. If existing users do not agree to the new terms and conditions, they will not be immediately excluded from their existing data. You receive limited read-only/export access according to § 4.

  6. After a content-relevant change to the General Terms and Conditions, renewed express consent may be required. Mere further use does not constitute consent.

  7. No names, email addresses, dates of birth or other additional personal data are collected for consent.

  8. The consent can be stored locally on the device used together with the existing pseudonymous technical user ID. Only: may be recorded:

    • the accepted version of the General Terms and Conditions,
    • the language of the displayed terms and conditions,
    • the time of consent,
    • confirmation that the minimum age of 18 years has been reached.

  9. The existing technical user ID is not a personal user account, not a personal registration and not proof of identity.

  10. If the local app storage is deleted, the application is reinstalled, or saved consent is removed, new consent may be required.

4. Read-only/export access for existing users

  1. Existing users who do not agree to the new or changed terms and conditions may continue to access their existing content to a limited extent and which is accessible according to the existing role and security architecture.

  2. Limited access only includes:

    • viewing existing events,
    • the reputation of existing community funds,
    • viewing existing bills, bookings and information,
    • the use of the actually existing PDF and Excel export functions,
    • opening the terms and conditions, the data protection declaration, the legal notice and the contact page,
    • the transmission of a cancellation, information, publication or deletion request.

  3. In particular, the following are not permitted without agreement to the current terms and conditions:

    • creating new events,
    • the creation of new community funds,
    • new bookings, deposits or expenses,
    • Changes or deletions of existing data,
    • new invitations or group assignments,
    • uploading new documents,
    • other writing or administrative processes.

  4. An existing user can reopen the consent dialog later. After effective consent, active use can be released again.

  5. Read-only/export access is used to view existing content, use existing export options and exercise legal rights. It does not constitute a claim to the continuation of all functions indefinitely.

  6. After a reasonable transition period, the free current usage contract can be properly terminated. The prerequisites are:

    • clear individual information about the affected user,
    • a reasonable period of time from receipt of this information,
    • a reasonable way to view existing content and use the exports actually available.

  7. A general publication on a website or in a generally accessible web document is not sufficient as an individual termination.

  8. As long as there is no technically addressable individual in-app communication channel or another individual contact channel, these General Terms and Conditions do not promise a specific, technically non-existent termination method from the provider.

5. Free introductory and trial operation

  1. There is no purchase price or subscription fee required for the current use of SiMaDoo. There is no payment transaction in favor of the provider via SiMaDoo.

  2. The individual three-month free period for your own cashbox features begins only when you first open the cashbox feature. The start and end are stored securely; reinstalling, changing devices or restoring access does not restart this period.

  3. Invited participants and members use their personal access free of charge within their role. Participation based solely on an invitation does not create a payment obligation.

  4. No prices, purchase products or subscriptions are currently approved for the period after the individual free period. A payment obligation can arise only from a later, separate and explicit agreement.

  5. Free provision is not a guarantee of unlimited or free use for life.

  6. In the future, SiMaDoo may offer additional or further developed services for a fee. Paid use does not arise automatically.

  7. Before concluding a fee-based contract, prices, scope of services, duration, termination conditions, consumer information and, if applicable, a right of withdrawal will be communicated separately.

  8. The switch to a paid service requires a separate, express contractual declaration from the user. Silence or mere continued use does not constitute an obligation to pay.

  9. These General Terms and Conditions do not contain any provisions regarding subsequent protection of existing assets or future prices.

6. User Responsibility

  1. Users are responsible for the completeness, accuracy and timeliness of their entries. This applies in particular to amounts, people, deposits, expenses, payment methods, cash balances, receipts and allocations.

  2. Calculation results are based on the data entered. SiMaDoo does not check whether a registered payment transaction actually took place or whether a registered claim legally exists.

  3. Users must independently check calculation results before making a payment, refund, billing, tax return or other economic decision.

  4. SiMaDoo does not become a party to the legal relationships existing between the users. The Application does not create, transfer or enforce claims between group members.

  5. Users may only enter personal data, receipts and other content that they are authorized to process.

  6. The existing PDF and Excel export functions affect individual event billing or community cash registers. They do not represent a complete export of all data associated with a technical user ID.

  7. An automated function for complete data release or complete deletion of all user data is not promised.

7. Acceptable Use and Abuse

  1. SiMaDoo may only be used for lawful purposes and within the scope of the functions provided.

  2. In particular, the following are prohibited:

    • Posting illegal, fraudulent or third-party rights-infringing content,
    • the use for deception, money laundering or concealment of illegal payment transactions,
    • spying on third-party access or circumventing access restrictions,
    • uploading malware or manipulated files,
    • automated access that places an unreasonable burden on operations,
    • manipulating or disrupting the application and its security features,
    • the unauthorized use of third-party names, technical identifiers or group access,
    • the distribution of receipts or personal data without the necessary authorization.

  3. If there is a reasonable suspicion of misuse, affected content, technical identifiers or group access can be temporarily restricted to the extent that this is necessary to check, avert danger or secure other users and is possible with the existing technical architecture.

  4. Before a permanent restriction is imposed, the affected user will generally be informed and given the opportunity to comment, provided there is a possibility of contact. This does not apply if immediate action is required due to significant security risks, criminal acts or imminent damage.

  5. Legal claims and official obligations remain unaffected.

8. Availability, Maintenance and Updates

  1. SiMaDoo is provided with reasonable care. There is no guarantee that availability will be uninterrupted or error-free at all times.

  2. Temporary restrictions may arise in particular due to maintenance, security measures, updates, disruptions to the Internet connection or failures of external infrastructure.

  3. If possible, planned maintenance work should be carried out or announced in such a way that the use is affected as little as possible.

  4. Required updates, including security updates, will be provided as required by law.

  5. Legal claims due to failure to provide, updates or defects in digital products are not restricted.

9. Changes to SiMaDoo and the Terms and Conditions

  1. Features may be changed or developed for valid reasons. Valid reasons are in particular:

    • technical developments,
    • security requirements,
    • changes in the legal situation,
    • the prevention of abuse,
    • necessary adjustments to operating systems or technical platforms,
    • improving usability or accessibility,
    • the discontinuation of functions that are no longer technically viable.

  2. Changes must not unreasonably disadvantage users. There are no additional costs for changes in free operation.

  3. Information about general or significant product changes can be provided within the app and in a permanently accessible, clearly versioned web document.

  4. To the extent that information is required by law to be on a durable medium, the relevant version must be able to be saved or downloaded unchanged and be available for a reasonable period of time.

  5. After a relevant change to the terms and conditions, a new consent dialog will be displayed the next time you start.

  6. First-time users cannot use the app without consent. If rejected, existing users will receive the read-only/export access described in Section 4.

  7. Purely editorial changes that do not change any rights or obligations can be made without further approval. The current version remains available with version information and date.

10. Rights to the Application and User Content

  1. The application, its design, program components, texts, graphics, logos and other proprietary content are legally protected.

  2. Users receive a simple, non-exclusive and non-transferable right to use SiMaDoo as intended for the duration of the user agreement.

  3. Reproduction, processing, further distribution, making publicly available or technical evaluation outside of the intended use is not permitted without permission, unless mandatory law permits otherwise.

  4. Rights to content posted by the user remain with the respective rights holder. The user only grants the provider the rights that are technically necessary to store, process and display this content to authorized group members.

  5. Technically necessary backup copies and legal retention requirements remain unaffected.

11. Data protection, information and content publication

  1. Information on the processing of personal data is contained in the applicable one Privacy Policy.

  2. Exercising statutory data protection rights does not result in the loss of contractual or statutory rights.

  3. Legal requests for information, correction, data release or deletion can be sent to info@simadoo.com be directed.

  4. Since there is no personal user account, technical user ID, identity and authorization must be sufficiently checked in each individual case. This may require, in particular, the technical identifier and information about affected events or community funds.

  5. Additional personal data may only be requested to the extent that it is necessary to examine and process the specific request.

  6. If there is a legal right to the publication of content, the relevant content will be made available in a common and machine-readable format free of charge, without unreasonable hindrance and within a reasonable period of time after successful identity and authorization checks.

  7. Paragraph 6 does not promise any automated export or download function. Release can be done manually after individual checking.

  8. The existing event and community cash register exports only capture the content specified in the export.

  9. Data from other group members will only be released to the extent that this is legally permissible and does not conflict with their rights.

  10. After the end of the contract, personal data will be deleted or anonymized in accordance with the data protection declaration and legal requirements, unless further storage is necessary or permitted.

12. Term and Termination

  1. The free usage contract is concluded for an indefinite period of time.

  2. Users can revoke the user agreement at any time without notice by email info@simadoo.com finish.

  4. Processing a cancellation may require a check of the technical user ID and authorization for the affected events or shared cash registers.

  5. The provider can generally terminate a free usage contract with a reasonable period of notice.

  6. An ordinary termination by the provider must be communicated individually and clearly to the user concerned. The notice period only begins with verifiable receipt of this individual notification.

  7. A general notice on the website, in a general web document or in a non-individually addressed app notice does not constitute an individual termination.

  8. As long as there is no technically addressable individual in-app communication channel or another individual contact channel, no specific ordinary termination method is guaranteed by the provider.

  9. Before regular termination, the affected user must be given an appropriate opportunity to view existing content and use the export functions that actually exist.

  10. The right of both parties to extraordinary termination for good cause remains. An important reason exists in particular in the event of serious or repeated misuse, circumvention of security measures or significant violation of the rights of other people.

  11. Termination does not automatically terminate other people's events or shared funds. Which group data is retained or deleted depends on roles, authorizations, the data protection declaration and legal requirements.

  12. Statutory termination and termination rights remain unaffected.

13. Liability

  1. The provider has unlimited liability:

    • in cases of intent and gross negligence,
    • in the event of culpable injury to life, body or health,
    • according to the provisions of the Product Liability Act,
    • in case of fraudulent concealment of a defect,
    • within the scope of an expressly assumed guarantee.

  2. 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 at the time the contract was concluded.

  3. Furthermore, liability for damage caused by slight negligence is excluded to the extent permitted by law.

  4. The liability regulations apply accordingly to legal representatives and vicarious agents.

  5. The provider is not liable for disadvantages that are based solely on the fact that a user has entered incorrect, incomplete or outdated data or has used a clearly incorrect result without checking. This does not exclude liability for your own technical errors.

  6. Mandatory legal rights for digital products remain unaffected.

14. Consumer Dispute Resolution

The provider is neither obliged nor willing to take part in a dispute resolution procedure before a consumer arbitration board.

15. Final provisions

  1. German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. Mandatory consumer protection regulations of the country in which a consumer has his or her habitual residence remain unaffected.

  2. If the user is a merchant, a legal entity under public law or a special fund under public law, the registered office of the provider is the place of jurisdiction, provided such an agreement is legally permissible.

  3. If a provision of these General Terms and Conditions is or becomes invalid, the statutory provisions shall apply in its place. The effectiveness of the remaining provisions remains unaffected.

16. Subsequent paid services

  1. These terms and conditions exclusively regulate the current free introductory and test operation.

  2. Paid services, subscriptions, in-app purchases or other payment obligations are not subject to these Terms and Conditions.

  4. Paid use requires a separate, express contractual declaration from the user.

17. Voluntary AI assistant

  1. The SiMaDoo AI assistant is a voluntary, supplementary help feature. Its answers are generated by artificial intelligence and may be incorrect, incomplete or out of date.

  3. Do not enter passwords, credentials, bank or card details, invitation codes or sensitive personal information in the input field.

  4. Rate limits, content filters, maintenance periods and other technical restrictions may apply to protect the service. There is no entitlement to uninterrupted availability or to a particular answer.

  5. Using the assistant creates no unapproved charges, subscriptions or purchase obligations. Statutory liability rights remain unaffected; in particular, statutory rights under section 13 are not restricted.

  6. The displayed data processing must be explicitly confirmed before a question is sent. Details are provided in the Privacy Policy. This addition explains the optional feature, creates no new payment obligation and therefore does not block existing users with a new general acceptance of the terms.
