(hereinafter "Provider").
The Software is used for managing rental properties, utility cost statements, homeowners association (HOA) billing, and tax receipt management for private landlords and HOA managers. It is available for macOS and Windows.
If you purchase the Software via the Apple App Store, Apple's terms of use also apply. In this case, these ToS constitute the applicable End User License Agreement (EULA) within the meaning of Apple's license model.
(1) The subject of these ToS is the granting of a non-exclusive, non-transferable license to use the ImmoManager Software on devices owned or controlled by the user.
(2) These ToS apply to all purchases of the Software, regardless of whether the purchase is made directly through the Provider or via the Apple App Store.
(3) Conflicting or deviating terms and conditions of the user shall not be recognized unless the Provider expressly agrees to their validity in writing.
(4) The Software is aimed at both consumers and businesses. Where these ToS do not expressly distinguish between consumers and businesses, the provisions apply equally to both groups.
(1) Purchase via the Apple App Store: The purchase contract is concluded between the user and Apple Inc. or the relevant Apple group company. In this case, the Provider does not act as a seller. However, the license to use the Software is granted by the Provider under these ToS.
(2) Direct purchase via the Provider's website: By placing an order, the user submits a binding offer to conclude a purchase contract. The contract is concluded upon receipt of the purchase confirmation by email or upon provision of the download link.
(3) The Provider does not permanently store the contract text in a form accessible to the user. Users should save or print these ToS themselves at the time of purchase.
(1) By purchasing the Software, the user acquires the right to install and use the Software on a reasonable number of Apple devices owned by the user and linked to the same Apple account (Family Sharing included).
(2) The license is non-transferable. Passing on, renting, leasing, or sublicensing the Software to third parties is not permitted.
(3) The purchase price entitles the user to all future updates of the Software provided via the same distribution channel, as long as the Provider offers updates for the respective operating system version.
(4) The user may not decompile, disassemble, reverse engineer, or otherwise attempt to derive the source code, unless expressly permitted by law.
(1) The purchase price is €34.99 (including statutory VAT) as a one-time purchase. No recurring fees or subscription costs apply. The use of AI features (e.g. automatic receipt analysis) may incur usage-based costs billed separately. The Provider will separately inform users of any AI costs prior to activation.
(2) When purchasing via the Apple App Store, Apple's payment terms apply. The Provider has no influence over the payment process or any taxes levied by Apple.
(3) For direct purchases, the payment methods specified on the website apply. Payment is due before the download link is provided.
(1) Consumers generally have a statutory right of withdrawal of 14 days.
(2) For purchases via the Apple App Store, the right of withdrawal is governed by Apple's terms. Refund requests must be directed to Apple.
(3) For direct purchases, the right of withdrawal for digital content expires early if the Provider has begun performance and the consumer expressly agreed before performance began that the right of withdrawal is lost once the Provider begins performance. The user declares this agreement by clicking the relevant confirmation checkbox during the purchase process.
(4) The right of withdrawal does not apply to businesses within the meaning of § 14 BGB (German Civil Code).
Withdrawal notice for consumers (direct purchase):
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 contract conclusion. To exercise the right of withdrawal, you must inform us (info@entropy-zero.de) by means of a clear declaration (e.g. by email) of your decision to withdraw from this contract. It is sufficient to send the notice of withdrawal before the withdrawal period expires.
Consequences of withdrawal: If you withdraw from this contract, we will refund all payments received from you promptly and no later than fourteen days from the day on which we receive notice of your withdrawal, using the same payment method you used for the original transaction.
(1) The Software requires: macOS 13 Ventura or later (Intel or Apple Silicon); Windows 10 or later (64-bit). The Provider assumes no responsibility for the Software functioning correctly on older or future operating system versions.
(2) The Software runs locally on the user's device. An internet connection is not strictly required for basic operation, but is needed for the initial download, updates, and use of AI features (receipt analysis via Claude API).
(3) The Provider may discontinue distribution of the Software or provision of updates at any time. Already purchased licenses are not affected; the user may continue to use the version available at the time of discontinuation.
(1) ImmoManager processes all data entered by the user exclusively locally on the user's device. No user data or property/tenant data is transmitted to the Provider's servers.
(2) The user is solely responsible for backing up their locally stored data. The Provider recommends regular use of Time Machine (macOS), File History (Windows), or comparable backup solutions.
(3) Where the Provider processes personal data of the user in connection with the purchase process (e.g. email address, name), this is done on the basis of Art. 6(1)(b) GDPR (performance of contract). Further information can be found in the Provider's privacy policy at entropy-zero.de.
(4) Since the app operates locally and no personal data is transmitted to the Provider, no Data Processing Agreement (DPA) is required.
(1) The Provider warrants that the Software has the agreed quality upon delivery and is fit for the customary or contractually assumed use.
(2) In case of defects, the user first has the right to subsequent performance (repair or replacement). If subsequent performance fails or is unreasonable, the user may reduce the purchase price or withdraw from the contract.
(3) The statutory warranty period is two years from delivery (provision of the download). For businesses, the warranty period is one year.
(4) The Provider provides updates to fix errors and maintain compatibility with current operating system versions. There is no legal entitlement to specific feature enhancements.
(5) For purchases via the Apple App Store, warranty is governed by Apple's terms where Apple acts as the seller.
(1) The Provider is fully liable for damages arising from injury to life, body, or health, and for damages caused by intent or gross negligence of the Provider or its agents.
(2) For ordinary negligence, the Provider is only liable in the event of a breach of a material contractual obligation (cardinal obligation), limited to the foreseeable, typical contractual damage. Material contractual obligations are those whose fulfillment enables proper performance of the contract and on which the user may regularly rely.
(3) Otherwise, the Provider's liability – particularly for indirect damages, lost profits, incorrect billing, tax disadvantages, or disputes with tenants or authorities – is excluded.
(4) The Software is a tool for managing rental properties and does not replace legal or tax advice. All documents and calculations generated are without warranty. The user is obligated to independently verify the results of the Software.
(5) The above limitations of liability do not apply where the Provider has fraudulently concealed a defect or has given a guarantee for the quality of the Software.
(6) For consumers, the above limitations of liability apply only to the extent permitted by applicable consumer law.
(1) The user agrees to use the Software only in accordance with these ToS and applicable laws.
(2) In particular, the following are prohibited:
(3) In the event of serious or repeated violations of these obligations, the Provider is entitled to terminate the license without notice. In this case, the user has no claim to a refund of the purchase price.
(1) If the Software is purchased via the Apple App Store, the user acknowledges that Apple Inc. (One Apple Park Way, Cupertino, CA 95014, USA) is a third-party beneficiary of these ToS.
(2) Apple has the right (and is deemed to have accepted the right) to enforce these ToS against the user as a third-party beneficiary.
(3) Apple is not a party to this End User License Agreement and bears no responsibility for the Software or its content.
(4) As between Provider and Apple, the Provider alone is responsible for the Software, any product liability claims, and compliance with laws and regulations.
(1) The Provider reserves the right to amend these ToS with future effect where there is good cause (e.g. legal changes, new distribution channels, new software features).
(2) For already purchased licenses, the ToS in force at the time of purchase apply, unless mandatory law requires an amendment.
(3) Material changes will be communicated to consumers by email, provided an email address is available.
(1) 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 the protection afforded by mandatory provisions of the law of the country in which the consumer has their habitual residence is not removed.
(2) The place of jurisdiction for all disputes arising from or in connection with this contract shall, to the extent permitted by law, be the Provider's registered office.
(3) Should individual provisions of these ToS be or become invalid or unenforceable, the validity of the remaining provisions shall not be affected. Invalid provisions shall be replaced by the applicable statutory rule.
(4) The EU Commission provides a platform for online dispute resolution (ODR): https://ec.europa.eu/consumers/odr. The Provider is neither obligated nor willing to participate in dispute resolution proceedings before a consumer arbitration board.
