Email / Support:
These Terms of Use supplement the terms applicable to the use, purchases, updates and features of the Helioporeo app.
If the app is obtained through the Apple App Store and the Provider has not made a separate End User License Agreement available in App Store Connect, the Apple Standard EULA applies to the licensing of the app. These Terms of Use do not replace the Apple Standard EULA. They supplement it to the extent that they relate to specific features, purchase models, updates, liability notices and usage notices for Helioporeo.
If the app is obtained through Google Play, the Google Play terms apply in addition to these Terms of Use, in particular with respect to downloads, purchases, payments, refunds and the use of the Google Play infrastructure.
By purchasing, downloading or using the app, you agree to these Terms of Use to the extent that they are validly incorporated into the contractual relationship.
1. Use of the App
The app is not sold, but licensed for use.
If the app is obtained through the Apple App Store, the licensing of the app is governed by the Apple Standard EULA, unless the Provider has made a separate End User License Agreement available in App Store Connect. These Terms of Use apply in addition to the Apple Standard EULA with respect to the specific purchase, update, use and feature model of Helioporeo.
If the app is obtained through Google Play or other distribution channels, you receive a personal, non-transferable, non-exclusive license to use the app on the supported devices and platforms.
2. One-Time Purchase and Major Versions
A one-time purchase unlocks the respective major version of the app that has been purchased.
A major version is the version before the first dot in the version number, for example:
- Version 1.x = major version 1
- Version 2.x = major version 2
- Version 3.x = major version 3
For example, if you purchase version 1.x, that purchase covers the use of major version 1 of the app.
3. Updates Included Within a Major Version
The purchase of a major version includes all updates, improvements, bug fixes, security updates and new features that the Provider releases within that major version.
Example:
A purchase of version 1.x includes, for example, versions 1.0, 1.1, 1.2, 1.3 and so on.
Updates within the same major version are provided without an additional purchase, provided that they are released by the Provider and the app remains available through the respective app store.
Legally required updates, in particular security updates, remain unaffected to the extent that the Provider is required to provide them under applicable law.
4. New Major Versions
The Provider may release a new major version of the app at a later date, for example version 2.x.
A new major version may be offered as a separate product, a separate in-app purchase or a separate upgrade. A purchase of an earlier major version does not create any entitlement to the free use of all future major versions.
The Provider is not obliged to release new major versions or to observe any specific period between major versions.
There is no entitlement to the app remaining permanently available in a specific app store, without prejudice to the user’s statutory rights.
5. No Guarantee of Specific Future Features
The Provider may further develop, improve and expand the app. However, there is no entitlement to any specific future features, content, integrations, platform support or extensions.
Descriptions of planned or possible features do not constitute a binding commitment unless they are expressly designated as part of the purchased product.
6. Availability and Technical Changes
The Provider endeavours to keep the app functional and up to date. Nevertheless, technical limitations or changes may occur due to operating systems, app stores, device manufacturers or third-party providers.
The Provider may modify, replace or remove features if there is an objective reason for doing so and the change is reasonable for the user. Objective reasons may include, in particular, technical, legal, security-related or material product-related reasons.
7. Purchases, Payments and Refunds
Purchases, in-app purchases, payments, invoicing, refunds and cancellations are processed through the respective app store, namely the Apple App Store or Google Play.
The terms of the respective app store apply in addition to these Terms of Use. To the extent that those terms contain mandatory provisions regarding payment processing or refunds, they take precedence for the respective app store transaction.
The Provider does not receive direct access to all payment and billing data of the user and can support refunds only within the options provided by the respective app store.
8. Permitted Use
You may use the app only within the scope of its intended functions and in accordance with applicable laws.
In particular, you must not:
- copy, resell or sublicense the app;
- circumvent technical protection measures;
- decompile, reverse engineer or otherwise attempt to derive the source code of the app, except to the extent expressly permitted by law;
- use the app in an abusive, unlawful or security-compromising manner.
9. Liability
The app is developed and provided with reasonable care. Nevertheless, it cannot be guaranteed that the app will be error-free, uninterrupted, free from technical security risks or suitable for a specific purpose at all times.
The Provider is liable without limitation in cases of intent and gross negligence, for damages resulting from injury to life, body or health, and under mandatory statutory provisions, in particular under applicable product liability laws. The same applies where the Provider has assumed a guarantee or fraudulently concealed a defect.
In cases of slight negligence, the Provider is liable only for the breach of a material contractual obligation. Material contractual obligations are obligations whose fulfilment is essential for the proper use of the app and on whose compliance the user may regularly rely. In such cases, liability is limited to the foreseeable damage typical for this type of contract.
For damages caused by improper use of the app, changes to the operating system, device defects, third-party services, lack of internet connection or failure by the user to make data backups, the Provider is liable only in accordance with the preceding paragraphs.
The user’s statutory rights in the event of defects and mandatory consumer rights remain unaffected.
10. No Guarantee for Specific Calling, Planning or Availability Decisions
Helioporeo is a visual time zone and planning assistant. In particular, the app displays local times, time zones, daylight, twilight, sunrise and sunset, golden hour, typical social hours, typical office hours and calculated overlapping time windows.
This information is provided for general orientation and planning purposes. It does not constitute a guarantee that a particular time will in fact be “perfect”, suitable or appropriate for all participants. In particular, the Provider does not guarantee that people will actually be reachable, available or online at the displayed times.
The social hours and office hours displayed in the app are based on general assumptions, in particular approximately 8:00 to 21:00 for usual calling hours and 9:00 to 17:00 for typical office hours. Actual working hours, public holidays, rest days, individual habits, cultural particularities, industry practices, shift work, local rules and personal availability may differ from these assumptions.
Information on daylight, twilight, sunrise and sunset, and golden hour is calculated on the basis of technical calculations and/or available data sources. It may vary depending on location, date, device settings, operating system, time zone and daylight saving time rules, data sources and calculation methods.
To the extent that Helioporeo is used for planning social media activities, the app does not provide an analysis of actual user activity, reach, engagement or likelihood of success. Displayed time windows are merely time-related orientation aids and do not constitute a recommendation or guarantee of the success of publications.
The user remains responsible for independently checking important appointments, times, time zones, availability and other planning decisions before using or sharing them, especially in business, legal, financial, health-related or otherwise important matters.
The user’s statutory rights in the event of defects in the app remain unaffected.
11. Privacy
Information on the processing of personal data, the services used, permissions and data subject rights can be found in the separate Privacy Policy, available at:
https://helioporeo.app/privacy.html
12. Changes to These Terms
Changes to these Terms of Use will be communicated to the user in an appropriate manner to the extent that they affect an existing user relationship.
Changes do not apply retroactively to the user’s disadvantage. For purchases already made, the terms that applied at the time of purchase generally continue to apply, unless a change is legally permissible or required.
The user’s statutory rights remain unaffected.
13. App Stores and Third-Party Terms
The app is made available through the Apple App Store and/or Google Play. For downloads, purchases, in-app purchases, refunds and the use of the respective app store infrastructure, the terms of the respective app store provider apply in addition to these Terms of Use.
If the app is obtained through the Apple App Store and the Provider has not made a separate End User License Agreement available in App Store Connect, the Apple Standard EULA applies to the licensing of the app. These Terms of Use do not replace the Apple Standard EULA, but supplement it with respect to the specific purchase, update, use and feature model of Helioporeo.
If the app is obtained through Google Play, the Google Play terms apply in addition to these Terms of Use, in particular with respect to purchases, payments, refunds and the use of the Google Play infrastructure.
The user agrees to comply with applicable third-party terms when using the app, in particular the terms of the Apple App Store, Google Play and any applicable terms of the user’s mobile network, internet or device provider.
14. Support
Support requests concerning the app may be sent by email to . No telephone support hotline is provided.
15. Language Versions and Translations
These Terms of Use may be made available in German, English and other languages.
The German and English versions are intended to be maintained as authoritative versions of these Terms of Use. Translations into other languages are provided for convenience only.
In the event of discrepancies between the German version and the English version, the version that is mandatory under applicable law or that is more closely connected to the relevant contractual relationship shall prevail. If no such mandatory rule or closer connection determines the applicable version, the English version shall prevail.
Translations into languages other than German or English do not modify the German or English versions and do not create independent contractual terms.
