Terms of use

1. Provider, scope and contract formation

The provider is Softwareentwicklung Kemper, owner Sebastian Kemper. Contact details are available in the Legal Notice (Imprint).

The new website provides information about smart3Dplanner and links to app offers. Its examined code has no checkout or user registration. Merely visiting a page is not intended to create a paid contract or blanket acceptance of these terms or data processing.

2. Digital products and usage rights

Confirmed by the operator: Android through Google Play and iOS through the Apple App Store are free to download, contain Google AdMob advertising and offer an optional monthly Pro subscription. Windows through Microsoft Store and the Steam version are paid downloads for a one-time price, with no in-app purchases or subscriptions. A free mobile download does not automatically include all Pro features. Removal of advertising after subscribing to Pro is not confirmed.

The actual functions, supported devices and requirements must be clear from the relevant offer before purchase. This information page promises no additional functions, accounts, cloud storage or public sharing service. Statutory rights in users’ own content and legally permitted activities are not excluded across the board.

Restoring purchases

Where technically supported for the particular purchase, acquired entitlements can be restored through the relevant app or store function. Whether and how this works for each product still requires confirmation. This information page promises neither restoration of every purchase type nor transfer between stores, platforms or accounts. Statutory claims concerning loss of access to paid services remain unaffected.

3. Mobile Pro subscriptions and desktop one-time purchases

Android and iOS: The optional Pro subscription is billed monthly through Google Play or the Apple App Store respectively. Under the applicable store terms, the auto-renewing subscriptions described there continue unless renewal is stopped. The subscription information displayed at purchase and applicable store terms govern; no specific prices or cancellation deadlines are stated here.

Manage and cancel a Google Play subscription through Google Play subscription management, or an Apple subscription through your Apple Account subscription management. Deleting the app does not cancel a store subscription. Stopping renewal, statutory withdrawal and refunds are separate matters. The particular offer must transparently identify which Pro features cease when the contract ends.

Windows and Steam: The download is offered through Microsoft Store or Steam for a one-time purchase price. These versions have no in-app purchases or subscription, so no subscription cancellation is required for them. A one-time purchase does not promise lifetime updates or cross-platform licences. The general terms “Subscription”/“Subscriber” in Steam's agreement do not establish a monthly Pro subscription for this product.

Official terms: Google Play, Apple Media Services, Microsoft Store and Steam. Store handling and the app licence agreement must be distinguished; mandatory rights are not limited by a blanket precedence clause.

4. Consumer rights and digital products

Mandatory consumer rights remain unaffected, including for the free basic version and advertising-funded use. Whether the digital product rules also apply to free use involving the provision of personal data requires separate assessment. Where the rules on digital products apply, sections 327 et seq. BGB must be considered, including supply, conformity, defect remedies and necessary updates including security updates. Referring users to a store does not exclude statutory claims.

5. Withdrawal and refunds

A purchase or download does not automatically exclude statutory withdrawal or defect rights. Early loss of a withdrawal right for digital content is possible only under the applicable legal conditions; a download alone or a blanket “no refunds” notice is insufficient. Subscription cancellation, withdrawal and defect claims are different matters.

Refunds depend on applicable statutory rights and any additional relevant store commitments. No blanket finality or refund guarantee is declared. Questions may be sent to contact.kemper.apps@gmail.com; this does not restrict legally available ways to exercise rights.

For store handling, consult the official refund information from Google Play, Apple, Microsoft Store and Steam. Conditions and procedures depend on the store, product, country and claim. This is neither a blanket refund promise nor an exclusion of statutory withdrawal or defect rights. Cancelling a subscription does not automatically produce a refund.

6. Liability and availability

This information page contains no departure from statutory liability. Statutory rules apply; in particular, mandatory liability and rights for death or personal injury, intent, gross negligence or under product liability law are not excluded. Statutory defect remedies remain available.

7. Privacy and third-party content

Processing of personal data is addressed separately in the privacy notice. Visiting the website or using an app is not blanket consent to arbitrary processing or international transfers. Third-party trademarks/content remain subject to their rights holders’ rights. The website loads YouTube only after permission.

8. Applicable law, jurisdiction and language

This information page makes no additional choice of law and agrees no exclusive forum. Statutory rules apply. Mandatory consumer protection and protected forums must not be removed by a blanket Germany/Mönchengladbach clause.

9. Changes

Changes to this information page are not intended to change existing contracts merely through publication. The former clauses permitting arbitrary changes without notice and acceptance through continued use are not carried forward. Statutory requirements for modifying digital products may also apply.
