1. Acceptance of Terms
By accessing or using Calius (the "Service", "we", "us"), you ("User") agree to be bound by these Terms of Service. If you do not agree, do not use the Service. By creating an account, claiming beta access, or using the software, you confirm that you have read and understood these Terms and that you enter into this agreement electronically.
2. Description of Service
Calius is an inventory management and cross-listing tool that interfaces with third-party platforms (including but not limited to Vinted and Kleinanzeigen). Calius is an independent service and is not affiliated with, endorsed by, or in any way officially connected to any third-party platform it integrates with. We do not guarantee continued availability of any integration or feature.
3. Third-Party Platforms and Account Risk
3.1
Calius may automate or assist with actions on third-party platforms on your behalf. By using the Service, you acknowledge and accept that:
- The use of third-party automation tools may violate the terms of service, policies, or community guidelines of those platforms, even if the Service is used as intended.
- Calius bears no responsibility for any action taken by a third-party platform against your account, including but not limited to: account suspension, permanent bans, listing removals, withheld payouts, strikes, restrictions, or legal action.
- You use the Service entirely at your own risk with respect to your accounts on any third-party platform. You are responsible for all activity conducted through your credentials and devices.
3.2
It is your sole responsibility to ensure your use of Calius complies with the terms of service, policies, and applicable laws for every platform you connect to the Service. We do not review your conduct on third-party platforms for compliance.
4. Invoices and Financial Data
4.1
Any invoices, sales summaries, revenue figures, or financial data generated or displayed by Calius are provided for informational purposes only. They do not constitute tax, legal, or accounting advice.
4.2
Calius does not guarantee the accuracy, completeness, timeliness, or legal compliance of any generated invoices, exports, or financial reports. Generated invoices may not meet the legal or formal requirements of your jurisdiction, industry, or tax regime.
4.3
You are solely responsible for:
- Verifying the accuracy of all financial data before any use or filing
- Ensuring invoices and records comply with applicable tax laws and regulations
- Filing taxes and reporting income correctly
- Retaining records as required by law
4.4
To the fullest extent permitted by law, Calius shall not be held liable for any financial loss, tax penalties, audits, disputes with buyers or platforms, or legal consequences arising from the use of, or reliance on, generated invoices or financial data.
5. Disclaimer of Warranties
The Service is provided "as is" and "as available" without warranties of any kind, whether express, implied, or statutory, to the extent permitted by law, including but not limited to:
- Warranties of merchantability, satisfactory quality, or fitness for a particular purpose
- Uninterrupted, timely, secure, or error-free operation
- Accuracy or reliability of any data, sync, or listing outcome
- That the Service will meet your requirements or integrate without interruption
- That defects will be corrected
Some jurisdictions do not allow certain warranty exclusions; in those jurisdictions, our warranties are limited to the minimum extent required by law.
6. Limitation of Liability
To the maximum extent permitted by applicable law, Calius and its operators, owners, affiliates, and contributors shall not be liable for any:
- Indirect, incidental, special, consequential, or punitive damages
- Loss of profits, revenue, goodwill, data, or business opportunities
- Account bans or restrictions imposed by third-party platforms
- Errors or inaccuracies in generated invoices or financial data
- Service interruptions, data loss, security incidents, or unauthorized access not caused by our intent or gross negligence
- Damages arising from your reliance on the Service or from third-party conduct
In no event shall Calius's aggregate total liability for all claims arising out of or related to the Service exceed the greater of (a) the amount you paid to Calius for the Service in the three (3) months preceding the event giving rise to the claim, or (b) zero if you have not paid any fees during that period.
Nothing in these Terms excludes or limits liability where such exclusion or limitation is prohibited by law, including liability for intent (Vorsatz), gross negligence (grobe Fahrlässigkeit), injury to life, body, or health, under mandatory product liability rules, or for breach of material contractual obligations (where applicable law limits the extent of such limitation to typical foreseeable damage).
7. Beta Access
During any beta or early-access period, the Service is provided without guarantees. Features may be incomplete, unstable, changed, or removed at any time. Beta users accept an elevated level of risk regarding data integrity, service availability, and compatibility. We may suspend or end beta access or migrate you to a paid plan with reasonable notice where we choose to do so.
8. Indemnification
You agree to indemnify, defend, and hold harmless Calius and its operators from any claims, damages, losses, liabilities, and expenses (including reasonable legal fees) arising out of or related to:
- Your use of the Service or your data and content
- Your violation of these Terms or applicable law
- Your violation of any third-party platform's terms, policies, or guidelines
- Any dispute between you and a third-party platform, buyer, or authority
- Any action taken against your accounts by third-party platforms
9. Changes to Terms
We may modify these Terms at any time. We will use reasonable means to notify you of material changes (for example via the Service, email, or dashboard notice). Where required by law, we will obtain your consent or offer a right to terminate. Continued use of the Service after changes become effective constitutes acceptance of the updated Terms, except where prohibited by mandatory law.
10. Governing Law and Venue
These Terms are governed by the laws of the Federal Republic of Germany, excluding its conflict-of-law rules. If you are a consumer habitually resident in the European Economic Area or the United Kingdom, nothing in these Terms affects mandatory consumer protection rules that apply to you and cannot be waived by contract.
Subject to mandatory law, exclusive jurisdiction for all disputes arising from or in connection with these Terms shall lie with the courts of Germany. If you qualify as a consumer, you may also bring proceedings in the courts of your place of residence where such rights are granted to you by mandatory law.
11. Severability
If any provision of these Terms is held invalid, illegal, or unenforceable, the remaining provisions remain in full force and effect. The invalid provision shall be replaced by a valid provision that comes closest to the economic intent of the original, where permitted by law.
12. Entire Agreement
These Terms constitute the entire agreement between you and Calius regarding the Service and supersede prior understandings on the same subject matter, except where we explicitly reference separate policies (for example privacy or acceptable use) that are incorporated by reference.
13. No Waiver
Our failure to enforce any right or provision of these Terms does not waive that right or provision. Any waiver must be in writing and signed by us to be effective.
14. Assignment
You may not assign or transfer these Terms or your rights under them without our prior written consent. We may assign these Terms in connection with a merger, acquisition, corporate reorganization, or sale of assets, provided your rights are not materially reduced without required notice where mandated by law.
