Terms of Use computor.at
Version 1.5, dated 25 October 2026
This version applies to new usage contracts. Existing contracts keep their terms until validly changed; version 1.4 remains available and links to version 1.3. The German version is authoritative.
1. Provider, account and free service
Graz University of Technology, Rechbauerstraße 12, 8010 Graz, Austria (“TU Graz”, “we”), operates computor.at through the Institute of Theoretical Physics – Computational Physics, Petersgasse 16, 8010 Graz. Contact details are in the Imprint. The learning service is free and funded by netidee.
These terms apply to registered users. Accepting them at first sign-in creates a free usage contract for an indefinite period. Public learning material can be read without an account. For TU courses, study regulations and course requirements take precedence if there is a conflict. The Privacy notice explains processing; acknowledging it is not consent under data protection law.
You must be at least 14. We delete accounts of younger people when we learn of them. Each person may have only one non-transferable account. Protect your password and email account and report suspected unauthorised access immediately to security@computor.at.
2. Learning, workspaces and additional tools
Computor offers courses and programming exercises, automatic tests, submission repositories, communication and learning help. The service explains which features and ways of working are available. Browser workspaces currently run on our servers; suitable tools on your device are an alternative. A browser interface does not mean computation happens on your device.
Computing time, memory, storage, network access, course places and concurrent workspaces are limited. Inactive workspaces may be stopped; their files remain. Capacity limits may temporarily prevent access; there is no entitlement to a particular course place. We operate with the care customary for a university learning service but cannot promise uninterrupted availability or recovery of individual files. Keep important work through Git or downloads.
Tests and points are learning aids, not an examination certificate or proof of competence. If a course uses results for assessment, the teacher decides under the applicable rules. Lena currently gives AI learning help through a button and course messages, including automatic routing in configured courses. It does not execute code or decide grades. The Privacy notice explains its context, audience and storage. Check AI answers because they may be wrong; availability and request limits depend on capacity.
Depending on the available feature, you work on your device or in a provided environment. External services you choose have their own terms and possible charges; they do not replace the agreed free service. The Privacy notice explains the data flows.
3. Acceptable use and your content
Use the platform to learn and teach. Resource abuse (such as unauthorised mining), spam, unauthorised attacks and port or vulnerability scans are prohibited. Network services, proxies, VPN/Tor nodes and security exercises are allowed where the course or platform provides or expressly permits them. Provided or expressly authorised course and platform features remain allowed, including those using agents. Do not bypass resource, access or participation limits, access other people's accounts or data, or try to escape the workspace. Illegal content, distributing malware, copyright infringement, child sexual abuse material, incitement to hatred, threats, harassment, insults and exposing other people are prohibited. Do not publish other people's submissions without consent or solutions to assessed exercises where the course prohibits it.
Security research needs prior agreement through security@computor.at. Report vulnerabilities confidentially without accessing other people's data or disrupting operations. We log usage-related technical access and security events where necessary for secure operation. The Privacy notice explains the data, purposes, authorised access and retention periods.
Your code, texts and files remain yours. You grant TU Graz only the free, non-exclusive rights to process your content as needed to operate the service, including storing, executing, automatically testing and showing it to your course's teaching staff and tutors, and showing course messages to their audience. These rights end on deletion; backup copies follow the deletion rules explained in the Privacy notice. Upload only content for which you hold the necessary rights.
Course material and software use their stated licences; rights in third-party material remain unaffected.
4. Moderation and appeals
We act on specific reports of legal or usage breaches; use Report content for illegal content. Measures depend on severity: a warning, removing or disabling content, stopping a workspace, temporary account suspension or termination. Automated tools flag anomalies; a human decides on measures against you. A workspace may stop automatically where there is acute danger.
We explain by email the measure, facts, rules concerned, use of reports or automated detection, and remedies, unless law or an authority prohibits this (Art. 17 DSA). You may appeal to contact@computor.at within six months. Appeals are reviewed under human supervision; we give you a reasoned outcome. You may go to court at any time. If we suspect a criminal offence threatening people's life or safety, we promptly inform the competent authorities (Art. 18 DSA).
5. Changing or ending the service or contract
We may change the technical implementation and add features without adversely changing the agreed services. We may unilaterally change the agreed services for technical, security, legal or operational reasons only if the change is minor, objectively justified and reasonable in light of your legitimate interests. Material adverse changes require a valid agreement with you or an applicable statutory change procedure. We give reasonable advance notice of substantial restrictions or planned closure and an opportunity to save your content. Necessary measures for urgent security issues or binding legal requirements may take effect immediately; we inform you without undue delay.
You may end the user contract at any time and request account deletion at privacy@computor.at. We may terminate on reasonable notice, taking your legitimate interests into account. Serious legal or usage breaches, or repetition despite a warning, may lead to suspension or immediate termination; the reasons and appeal rights in section 4 still apply. Statutory rights remain unaffected.
Accounts unused for 24 months follow this deletion rule: we give reasonable advance warning by email; signing in during that period keeps the account. Deletion is handled across the services involved and is not completed merely by archiving an account. The Privacy notice explains legally required retention and backups.
6. Liability
We are liable under the law for damage caused intentionally or through gross negligence. We exclude liability for slight negligence except for personal injury, damage to items accepted for processing, and mandatory liability, including under the Austrian Product Liability Act or Art. 82 GDPR. Statutory warranty rights remain to the extent applicable to this free contract.
Failure to keep copies as recommended in section 2 may count as contributory negligence for data loss (§ 1304 ABGB). You are liable under the law for culpable breaches of these terms. This does not transfer TU Graz's own legal obligations to you.
7. Law and jurisdiction
Austrian law applies without its conflict-of-law rules. This choice does not deprive consumers of the mandatory protection of the law of their habitual residence where Article 6 of the Rome I Regulation applies. Statutory jurisdiction rules remain unaffected. For businesses, the court in Graz with subject-matter jurisdiction is competent.
8. Changes to these terms and contact
We inform you of significant changes to these terms. Where your agreement is required, we obtain it separately.
