Terms of service
Last updated: November 8, 2026
These terms govern Postmina provided by Sellrock UG (haftungsbeschränkt), Kölner Str. 43a, 90425 Nürnberg, Germany. Postmina is offered to businesses and professional users acting for their organization. An individually agreed contract takes precedence.
The service
Postmina supports business briefings, drafts, reviews, scheduling and authorized social publishing where the relevant integration is available. You must have authority to act for your workspace and connected accounts. Keep credentials secure and permissions current. Features requiring provider approval, credentials or a separate order are available only when those requirements are met.
Your content
You retain rights in your submitted material and authorize us to process it only to provide the service. You are responsible for the necessary rights, lawful instructions and the accuracy of claims, offers and approvals. Do not submit unlawful material or use Postmina to evade platform restrictions. AI suggestions can be inaccurate and must be reviewed. Publication requires the applicable approval; editing a revision does not preserve approval of the old revision.
Trial and payment
Any trial limits, paid services, prices, taxes, billing intervals and renewal conditions are those expressly shown and accepted in the relevant offer or order. A trial does not itself authorize charging you. No purchase or payment obligation arises solely from connecting a social account. Where payment is due, the agreed invoice and order terms apply.
Ending the contract
You may request cancellation or account closure at info@postmina.com. Any agreed paid term and notice conditions remain governed by your order. Access may be restricted where necessary to address unlawful use, a concrete security risk or a material contractual breach. Data deletion follows our privacy policy; disconnecting a channel is not account closure and does not remove a post already published by a platform.
Platform dependencies and publication
Social platforms control access, review, quotas and delivery and can change or withdraw them. We do not guarantee a specific reach, engagement, uninterrupted availability or publication at an exact second. A timeout after submission may require reconciliation rather than an automatic retry. Do not assume a paused or disconnected connection retracts a request already accepted externally.
Liability
Statutory liability for intent, gross negligence, injury to life, body or health and other mandatory liability remains unlimited. For ordinary negligence, liability for breach of a material contractual obligation is limited to foreseeable damage typical for the contract, to the extent legally permitted. This does not restrict mandatory rights or an expressly assumed guarantee.
Applicable law and contact
German law applies, subject to mandatory applicable law. Where a jurisdiction agreement is legally permitted, the courts at our registered office have jurisdiction. Questions about these terms and service arrangements can be sent to info@postmina.com.
