§ 1 Scope and contracting party
These Terms of Service govern the use of the AQVELIS app by registered users. The provider of the service is Florian Krenn, Dornhof 14, 9300 Frauenstein, Austria (contact: support@aqvelis.at). By registering an account, you enter into a usage agreement with the provider under these terms.
§ 2 Description of services
AQVELIS is a currently free service for managing water environments: pools, spas (hot tubs), freshwater aquariums and saltwater aquariums. Using the app, you can:
- create and manage one or more water environments with name, facility type and volume,
- record measurements for your water environments,
- set personal target ranges for individual measurement parameters,
- assign products from the AQVELIS product catalog to your water environments,
- view dosing notes for the assigned products based on curated manufacturer information.
A data field is provided for measurement devices; active synchronization with external sensors or measurement devices does not currently take place.
§ 3 Registration, account and minimum age
A user account is required to use AQVELIS. You can register with an email address and password or via your Google account. As a prerequisite for using AQVELIS, you must be at least 14 years old to register and use an account.
§ 4 User obligations
When using AQVELIS, you are obliged
- to adequately protect your access data (in particular your password) and not to pass it on to third parties,
- not to use AQVELIS in an abusive manner or in a way that violates applicable law,
- not to intentionally disrupt or manipulate the service.
§ 5 Water care and dosing notes
Dosing notes and recommendations for target ranges that are displayed to you in the app are based on curated information from manufacturer specifications for the respective products. They do not replace the instructions of the respective manufacturer or any professional on-site assessment that may be required in individual cases. AQVELIS does not guarantee that these notes are error-free, complete or suitable for your specific situation in every individual case. The decision about the actual water care and dosing is yours.
§ 6 Liability
AQVELIS is liable within the scope of the statutory provisions. Mandatory statutory liability provisions remain unaffected.
§ 7 Availability
AQVELIS strives to operate the service reliably, but does not guarantee any particular or uninterrupted availability. Maintenance work, technical faults and the further development of the service may lead to temporary restrictions or interruptions.
§ 8 Deleting your account
You can delete your AQVELIS account yourself at any time. You can find the corresponding menu item in the app under:
Settings → Danger Zone → “Delete Account”
After selecting “Delete Account”, you confirm the process in two steps; finally, you confirm with “Delete Account Permanently”. In the process, your profile, your legal consents, your water environments/facilities, measurement target ranges, measurements, product assignments to your facilities and measurement device metadata are completely deleted. Global product catalog data remains, as it is not assigned to you personally.
If you no longer have access to the app, you can request the deletion of your account by email to support@aqvelis.at.
§ 9 Restriction or termination by AQVELIS
AQVELIS may restrict or terminate access to your account if there is an objective reason, in particular in the case of
- significant or persistent violations of these Terms of Service,
- abusive or unlawful use of the service,
- a specific security risk to the service or to other users,
- a legal obligation on the part of AQVELIS to restrict or terminate access.
Where appropriate and possible in the circumstances, AQVELIS will inform you in advance of a planned restriction or termination. In urgent or serious security or legal cases, an immediate restriction without prior notice may be necessary.
§ 10 Changes to these Terms of Service
AQVELIS may present a new version of these Terms of Service, for example if the legal situation or the scope of functions of the app changes. If renewed consent is required for the new version, AQVELIS will inform you in the app about the essential changes. You can only continue to use the app after you have expressly agreed to the new version. Consent by mere silence is not provided for.
§ 11 Applicable law
This contract is governed by Austrian law. If you are a consumer with your habitual residence in another EU member state, the mandatory consumer protection provisions of the law of your habitual residence remain unaffected.
§ 12 Place of jurisdiction
For disputes arising from or in connection with this contract, the statutory places of jurisdiction apply, in particular the consumer protection jurisdiction rules pursuant to § 14 KSchG and the relevant EU provisions on jurisdiction in consumer matters.
