2. Terms for Designers

2.1 Rendering Hour Packages
- Designers can purchase rendering hour packages, which grant access to our rendering services.
- The prices for rendering hour packages and all other services are exclusive of VAT (value-added tax). VAT application depends on the customer's location and tax status:
•    EU-based B2C Customers (Non-Business): VAT is applied at the applicable local rate of the customer's EU country.
•    EU-based B2B Customers (Businesses with VAT ID): No VAT is charged if a valid VAT ID is provided during the purchase process, as per the reverse charge mechanism under EU VAT rules.
•    Austrian Businesses: VAT is applied but can be reclaimed according to Austrian tax regulations.
•    Non-EU Customers: No VAT is charged for B2B customers located outside the EU.
Customers are responsible for ensuring their VAT information is accurate and up-to-date. Any issues arising from incorrect or incomplete tax information provided by the customer are the customer's responsibility.
- Rendering hours are valid for a minimum of one year from the date of purchase.
- Prepaid Rendering Hours: Prepaid rendering hours are non-refundable and will become invalid in the event of Praxagoras GmbH's bankruptcy, closure, or dissolution. Prepaid rendering hours may be subject to claims under Austrian insolvency law, which could affect their validity during bankruptcy proceedings.
- Rendering hours are non-transferable and may only be used by the purchasing account unless explicitly authorized by Praxagoras GmbH.

2.2 Consumer Right to Withdrawal
- Under Austrian and EU law, consumers typically have a 14-day right to withdraw from contracts made online (unless an exception applies, such as the immediate provision of digital services).
- For rendering hour packages, designers may withdraw from the purchase within 14 days unless they explicitly consent to the immediate provision of rendering services.
- Consent to Immediate Provision: By using the rendering services, designers explicitly consent to the immediate provision of services, which waives the 14-day withdrawal right once services commence.

2.3 Initial Free Trial
- Designers who are first-time users may qualify for a promotional free trial. The trial's duration and conditions depend on the specific offer.
- Free trials will end automatically unless the user explicitly subscribes to a paid plan.
- No credit card is required to begin a free trial.

2.4 Fair Use Policy
- Users are limited to having one job actively rendering at a time and one job waiting in the queue. This system is designed to ensure fair and equitable access to rendering resources for all users.

- Excessive or Disruptive Use:
Any attempts to bypass this system, such as:

• Using multiple accounts to exceed the job limit.
• Manipulating the platform to gain additional access to rendering resources.

Such actions will be considered a violation of the Fair Use Policy. 
Praxagoras GmbH reserves the right to suspend or terminate accounts found in violation of these measures, with notice provided to the user and an opportunity to rectify the issue where possible. First-time violations will result in a warning and temporary suspension of services. Repeat violations may result in account termination.

- Rendering time is calculated in minutes per node that is actively rendering. Partial minutes (e.g., seconds) are not counted towards the rendering time.

- Rendering Hours Exhaustion:

If a designer runs out of rendering hours while a job is being processed:

• No Frames Rendered: If no frames are completed during the remaining rendering time, this time will be lost, and the job will be paused automatically.
• Completed Frames: If one or more frames are successfully rendered before the rendering hours are used up, these frames will be made available for download.
• To continue the paused job, the designer must purchase additional rendering hours. Once rendering hours are added to the account, the job can resume from where it was paused.

2.5 Data Protection & Privacy
- Designer data is securely stored in an encrypted environment. We adhere to GDPR regulations.
- Projects’ files are only processed for rendering purposes and are deleted upon completion when removed from the Job Handler.
- Metadata Retention: Metadata related to rendering jobs is retained securely for up to 7 years for statistical and managerial purposes. After 7 years, metadata will be anonymized unless otherwise required by regulatory obligations.
- Data Transfers: Rendering tasks may involve processing on nodes located outside the European Economic Area (EEA). Praxagoras GmbH ensures compliance with GDPR through safeguards such as Standard Contractual Clauses (SCCs) or equivalent mechanisms.- Right to Be Forgotten: Users may request the deletion of project metadata at any time, subject to legal and regulatory obligations. Praxagoras GmbH will comply with such requests within the statutory timeframe to ensure compliance with GDPR's "right to be forgotten."
- Confidentiality: Praxagoras GmbH will not access or use uploaded files for any purpose other than rendering services unless explicitly authorized by the user. Systems are designed to ensure files remain confidential.
- User Notification: Users will be informed about all data processing activities and retention policies at the point of registration and file upload. Please refer to our Privacy Policy for details.
- In the unlikely event of a data breach affecting uploaded files or personal data, users will be notified without undue delay, in compliance with GDPR Article 33. This notification will include details of the breach, its potential impact on personal data and intellectual property, and the measures taken to mitigate risks and prevent future breaches.

2.6 Service Availability & Limitation of Liability
- While Praxagoras GmbH strives for continuous service availability, external factors (e.g., rendering host availability) may cause delays. Praxagoras GmbH cannot compensate for such delays.
- Praxagoras GmbH is not liable for any failure to perform due to causes beyond its reasonable control, including but not limited to natural disasters (e.g. earthquakes, floods), cyberattacks, strikes, government-imposed restrictions or sanctions, or infrastructure failures. Praxagoras GmbH will notify users promptly of any such events and their anticipated impact on services.

After this period, the files will be permanently deleted from our servers unless otherwise agreed in writing before the render order is placed. Customers are responsible for downloading their render results within this timeframe.

2.10 Limitation of Responsibility for Projects
- Praxagoras GmbH is not responsible for the content, legality, or quality of projects created by designers and rendered using our platform. Designers are solely responsible for ensuring their projects comply with all applicable laws and do not infringe on third-party rights.
