of Weiß & Siebert Solutions GmbH for the use of Revmatis
This is a translation provided for convenience. In the event of any discrepancy, the German version prevails.
These terms govern the use of the software "Revmatis", which we, Weiß & Siebert Solutions GmbH, Stuttgart (commercial register HRB 803077, Stuttgart Local Court), provide as an online service.
We offer Revmatis exclusively to entrepreneurs within the meaning of section 14 of the German Civil Code and to legal entities under public law. No contract is concluded with consumers.
Your own terms and conditions apply only if we agree to them in text form.
Revmatis helps your sales team find, evaluate and approach target companies. The scope depends on the plan you book, as set out in the service description (Annex 1).
Revmatis works with artificial intelligence. Analyses, scores and suggested texts are machine-generated assessments based on publicly accessible sources. They may be incomplete or incorrect. We owe you the provision of the software, not the correctness of its results. Please review results before you use them.
We do not provide legal, tax or management consulting.
The presentation of plans on our website is not a binding offer. The contract is concluded once we confirm your order in text form or activate your access.
For the term of the contract you receive the right to use Revmatis for your own business purposes. Accounts are personal and may not be used by several people at the same time or by third parties. Replacing one user with another is permitted.
You hold the rights to your data and to the results generated for you. We process them only to perform the contract. We may evaluate anonymous usage statistics that cannot be traced back to you in order to improve the software.
Your plan includes monthly allowances for analyses and AI features. Allowances not used in a given month remain available in the following month and expire thereafter. With annual billing we grant the full annual allowance at the start; at the end of the year up to 20 percent may be carried over.
Usage beyond the allowance is billed at the prices set out in Annex 1. A monthly cap applies to overage. Once it is reached, we block further chargeable usage until you raise the cap or a new billing period begins. We will notify you in text form when we do. You will not incur costs above the cap. The amount of the cap is set out in Annex 1; you may agree a different cap with us in text form.
All prices are net and exclusive of VAT. Fees are payable in advance; overage is billed in arrears. Invoices are due within 14 days without deduction.
If you are in default with a not insignificant amount for more than 30 days, we may suspend access after prior notice and a reasonable grace period. Your payment obligation remains.
We may adjust prices with three months' notice effective at the end of a term. If the price increases by more than 5 percent, you may terminate within four weeks with effect from the date the change takes effect. We will point this out in our notice.
You may offset only against claims that are undisputed or have been finally determined by a court.
The contract runs monthly or annually, as agreed, and renews for the same term. The notice period is one month for monthly terms and three months for annual terms, in each case effective at the end of the term. Termination requires text form.
The right to terminate for cause remains unaffected. For us, cause exists in particular if you breach section 7 and fail to remedy the breach despite being asked to do so.
You can export your data through the software's export functions until the contract ends. Deletion thereafter is governed by the data processing agreement.
You decide which companies and individuals you research, evaluate and approach.
You are responsible for the lawfulness of every contact you make, in particular under competition law and data protection law. Revmatis generates suggested texts; you alone decide on recipients, channel, timing and sending. We do not send any messages to the people you research.
Under data protection law you are the controller within the meaning of Article 4(7) GDPR. You determine the legal basis and fulfil the information obligations under Articles 13 and 14 GDPR.
Please keep your credentials confidential and notify us if you suspect unauthorised use. Do not enter special categories of personal data within the meaning of Article 9 GDPR into the software.
If you connect your own accounts with third-party services, you remain their contracting party and are responsible for lawful use. We are not a processor in this respect.
If you breach these obligations, you shall indemnify us against third-party claims, including reasonable costs of legal defence. This does not apply where you are not responsible for the breach.
We strive for high availability but do not guarantee uninterrupted access. We may temporarily interrupt the software for maintenance, updates and bug fixes; where foreseeable interruptions exceed 30 minutes we will announce them where possible.
Disruptions outside our sphere of control, for example of the internet, at upstream providers or at third-party services you have connected, are not attributable to us.
We develop Revmatis continuously. We will announce material reductions in scope three months in advance; you may then terminate with effect from the date the change takes effect.
German rental law applies to the provision of the software. Strict liability irrespective of fault for defects already present at the time the contract was concluded (section 536a(1) first alternative of the German Civil Code) is excluded. Reduction of the fee by way of deduction is excluded; you may assert reduction claims separately.
We are liable without limitation for intent and gross negligence, for damage arising from injury to life, body or health, under the German Product Liability Act, and to the extent of any guarantee we have given.
In cases of ordinary negligence we are liable only for breach of material contractual obligations, limited to the damage foreseeable and typical for this type of contract at the time of conclusion, and capped at the net fees you paid in the preceding twelve months. Any further liability is excluded.
We are not liable for damage arising because machine-generated results were used without the review required under section 2. For loss of data we are liable only up to the expense that would have been necessary to restore the data had it been backed up properly; our backup obligations under the data processing agreement remain unaffected.
These limitations also apply in favour of our legal representatives and vicarious agents.
Where we process personal data on your behalf, we conclude a data processing agreement with you under Article 28 GDPR (Annex 2). In matters of data protection it takes precedence over these terms. The technical and organisational measures are set out in it; we may develop them further as long as the agreed level of protection is maintained. How we process data when you visit this website is described in our privacy policy.
We treat your confidential information as confidential and use it only to perform the contract. We expect the same from you. This does not cover information that is public or becomes public without a breach of this obligation. The obligation continues for three years after the contract ends.
We will name you as a reference only with your prior consent in text form.
We may change these terms where this is necessary due to a change in the law, in case law or in the scope of the service, and where you are not unreasonably disadvantaged as a result.
We will notify you of changes in text form at least six weeks before they take effect and will point out your right to object. If you do not object before the changes take effect, they are deemed accepted. If you object, either party may terminate with effect from the date the change takes effect.
German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. The exclusive place of jurisdiction is Stuttgart, provided you are a merchant or a legal entity under public law. Amendments require text form. Should any provision be invalid, the remaining provisions remain effective.
