Terms.

This is a convenience translation of the German original. The German version is the legally binding one; where the two differ, the German text prevails.

1. Scope and provider

These terms govern the use of verstag, a software service provided by REVERCE GmbH, Hofaue 35, 42103 Wuppertal, Germany (“we”, “us”). verstag is directed at businesses and professional users (B2B) and is not offered to consumers. By entering into the contract you represent that you act as an entrepreneur within the meaning of § 14 of the German Civil Code (BGB), as a legal entity under public law or as a special fund under public law.

Your own terms and conditions do not apply, even where we do not expressly object to them. They apply only to the extent we have expressly agreed to them in text form.

2. The service

verstag allows workspaces to verify the C2PA provenance of images and videos, manage them in a library, derive channel-specific versions with optional AI labelling, and export derivatives carrying a C2PA manifest signed with the workspace’s signing identity.

3. Accounts and workspaces

Access requires an account and membership in a workspace. Workspace owners and administrators manage members, invitations, policies and signing settings, and are responsible for the activities of the members they admit. Credentials must be kept confidential.

4. Trial period

A new workspace starts with a trial period of 14 days on the largest self-service plan; no payment method is required for it. The trial period ends automatically, without any termination being necessary. The workspace then continues on the free plan with its limits, unless a paid plan is booked; we make stored content available for export for 30 days from the end of the trial period, after which the retention and deletion rules in clause 8 apply with the limits of the free plan. Each customer is entitled to the trial period once.

5. Customer content

You retain all rights in the image and video files and other content you upload. You grant us the non-exclusive right to store, process, render and sign that content solely in order to provide the service. You warrant that you hold the rights required to upload and process the content and that its use infringes no third-party rights and no applicable law.

6. Acceptable use and suspension

You must not upload unlawful content, attempt to circumvent workspace isolation or signing controls, misrepresent provenance, or use the service to create misleading claims of authenticity.

We may temporarily suspend access to the service where there are concrete indications of a breach of these terms or of applicable law, or where suspension is necessary to protect the integrity or security of the service or its users. We will inform you of the suspension and its reason without undue delay in text form, unless doing so would defeat the purpose of the suspension or is not legally permitted. The suspension is lifted as soon as its reason no longer exists.

7. C2PA signatures and provenance

A verstag signature confirms that a derivative was processed and exported through verstag for the signing workspace at a particular time. It is not a statement about the truth, authorship or lawfulness of the content depicted. Whether third parties trust a signature is determined by their own trust lists and validators and is outside our control. Verification results reflect the manifest data embedded in the file at the time of the check.

8. Retention and deletion

Workspaces may set a retention period for stored image and video files. If a workspace sets no period, the platform default applies; it is shown in the workspace and can be changed there. Once the applicable period expires, binaries are permanently deleted — even without a period of the workspace’s own; provenance and audit records are kept as evidence. Deleted binaries cannot be restored.

9. Availability

We provide the service with reasonable care and skill, but do not warrant uninterrupted availability. Scheduled maintenance and circumstances outside our control (including third-party infrastructure) may affect availability.

10. Fees and payment

The fees are those shown at the time of booking in the workspace or on the pricing page. All prices are net prices plus the applicable value added tax.

The base fee is charged in advance for each billing period of one month. What counts is the seat quantity booked in the workspace, not its occupancy. Changes to the booked quantity and plan upgrades are settled pro rata from the time of the change; plan downgrades take effect at the end of the current billing period.

Usage-based fees are incurred only where the spending cap has been switched off in the workspace; while it is on — the default — usage above the included allowance is refused rather than charged. Storage above the allowance is charged at the level of the last daily measurement in the billing period, video minutes are summed over the period; both are invoiced after the end of the respective billing period.

Payment is collected automatically from the payment method on file with our payment provider. Invoices are provided electronically.

If collection fails, we retry it and request payment in text form. If payment remains outstanding after a reasonable grace period, we may restrict the workspace to read access and export and subsequently end the paid contract; the workspace then continues on the free plan in accordance with clause 12 paragraph 4. Statutory default remedies remain unaffected.

You may set off only claims that are undisputed or have been finally established by a court.

11. Liability

We are liable without limitation for intent, gross negligence, and for injury to life, body or health. For slight negligence we are liable only for breach of material contractual obligations (cardinal obligations) — obligations whose fulfilment makes the proper performance of the contract possible in the first place and on whose observance you may regularly rely — limited to the damage typical and foreseeable for this type of contract. Liability under mandatory statutory provisions remains unaffected.

12. Term and termination

Billing is monthly. Without an agreed minimum term, the contract may be terminated at any time with effect from the end of the current billing period.

Where a minimum term is chosen, the contract runs for the chosen period and then renews automatically for the same period each time, unless renewal is switched off before the end of the minimum term then running. Renewal can be switched off in the workspace at any time and is not a termination: the contract does not end, but continues monthly at the regular price from the end of the current minimum term, and can be terminated monthly from that point.

Termination is also possible at any time during a minimum term; it takes effect at the end of the minimum term then running. A discount granted for the minimum term is retained for the duration of each renewal; if renewal is switched off, the regular price applies from its end.

The right to terminate for cause remains unaffected. After a paid contract ends, the workspace continues on the free plan; we make stored content available for export for 30 days from the downgrade, after which the retention and deletion rules in clause 8 apply with the limits of the free plan.

13. Changes

We may amend these terms with effect for the future where there is good cause to do so — in particular a change in the law or in case law, or the technical or functional evolution of the service — and the amendment does not shift the balance of performance and consideration to your disadvantage. Amendments to the subject matter of the service, the fees, the term provisions or the liability provisions require your express consent.

We announce amendments in text form at least six weeks before they take effect. If you do not object before they take effect, the amended terms apply; in the announcement we point out separately your right to object, the deadline and this effect. If you object in time, the contract continues under the previous terms; we may then terminate it ordinarily with effect from the end of the current billing period or of a current minimum term. In addition, you may terminate the contract for cause with effect from the date an announced amendment takes effect, at any time before that date.

14. Data protection and processing on your behalf

Where we process personal data on your behalf in providing the Service, the Data Processing Agreement applies. It is attached to these terms as Appendix 1 and is agreed together with them. It governs the subject matter, nature and scope of that processing, the technical and organisational measures, and the sub-processors engaged. Where these terms and Appendix 1 conflict, Appendix 1 prevails for the processing it governs.

Which personal data we process as controller — your account and billing data in particular — is set out in the privacy notice.

15. Governing law and jurisdiction

German law applies, excluding the UN Convention on Contracts for the International Sale of Goods (CISG). The exclusive place of jurisdiction is Wuppertal, Germany, to the extent permitted.
