Terms & Conditions

Last updated: March 21, 2026

1. Operator

CalMesh is operated by Berliner Softwareschmiede UG (haftungsbeschränkt), In der Gasse 6, 14550 Groß Kreutz, Germany ("we", "us", "the Operator"). These terms govern your use of CalMesh (calmesh.xyz) and are accepted by creating an account.

Contract language: English. Governing law: Federal Republic of Germany.

2. Description of Service

CalMesh provides calendar aggregation, scheduling, and booking infrastructure via a web application, REST API, and MCP server. We act as a technical intermediary between your calendar providers and your applications.

3. Account & Eligibility

You must be at least 16 years old to use CalMesh. You are responsible for maintaining the confidentiality of your account credentials and API keys. You are liable for all activity under your account to the extent caused by your failure to safeguard your credentials.

4. Subscriptions & Billing

Paid plans are billed annually in advance via Mollie. All prices are in EUR and include VAT where applicable. A 14-day free trial is provided; you will not be charged before the trial expires. We may change prices with 30 days' prior notice; the new price applies at the start of your next billing period.

If you cancel during a billing period, your access continues until the end of the paid period. Unused time on annual plans is refunded pro-rata upon request, except where cancellation is due to a breach of these terms by you.

5. Right of Withdrawal (Widerrufsrecht)

If you are a consumer in the EU, you have the right to withdraw from this contract within 14 days without giving any reason. The withdrawal period expires 14 days after the day of the conclusion of the contract.

To exercise the right of withdrawal, you must inform us — Berliner Softwareschmiede UG (haftungsbeschränkt), In der Gasse 6, 14550 Groß Kreutz, Germany, hello@calmesh.xyz — of your decision to withdraw from this contract by an unequivocal statement (e.g. a letter sent by post or e-mail).

If you withdraw, we shall reimburse all payments received from you without undue delay and in any event not later than 14 days from the day on which we are informed of your decision to withdraw. We will carry out such reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.

If you requested to begin the performance of the service during the withdrawal period, you shall pay us an amount which is in proportion to what has been provided until you communicated your withdrawal, in comparison with the full coverage of the contract.

Loss of withdrawal right: You agree that the withdrawal right expires once the digital service has been fully performed, provided that performance began with your prior express consent and your acknowledgement that you thereby lose your right of withdrawal. This consent is obtained during the sign-up process.

We reserve the right to suspend or terminate accounts that materially violate these terms after giving reasonable notice where practicable. In the event of termination for cause, you are entitled to a pro-rata refund of any prepaid, unused service period.

7. Intellectual Property

All rights to the CalMesh software, brand, documentation, and infrastructure remain with the Operator. Your data remains yours. We claim no ownership of calendar data passing through our service.

8. Service Quality & Defects

We endeavour to provide CalMesh with reasonable care and skill in accordance with generally accepted industry standards. Where the service does not conform to this standard, you are entitled to the statutory remedies available under applicable law.

We do not warrant that the service will be uninterrupted or entirely error-free. Where we become aware of material defects, we will use commercially reasonable efforts to remedy them within a reasonable timeframe.

9. Limitation of Liability

Our liability for damages arising from the use of CalMesh is limited as follows:

  • Unlimited liability: We are liable without limitation for damages caused by intent or gross negligence, for injury to life, body, or health, and for liability under mandatory statutory provisions including the Product Liability Act (Produkthaftungsgesetz).
  • Simple negligence — cardinal obligations: For breach of essential contractual obligations (Kardinalpflichten) caused by simple negligence, our liability is limited to the foreseeable, contract-typical damages. This is limited to the greater of (a) the amount you paid us in the twelve (12) months preceding the event giving rise to the claim, or (b) EUR 50.
  • Simple negligence — other obligations: We are not liable for breach of non-essential obligations caused by simple negligence.
  • Indirect damages: Liability for indirect, incidental, or consequential damages (including loss of profits or data) is excluded to the extent permitted by law.

10. Force Majeure

Neither party shall be liable for any failure or delay in performing its obligations where such failure or delay results from circumstances beyond the reasonable control of that party, including but not limited to natural disasters, war, terrorism, pandemics, strikes, government actions, power failures, internet outages, or failures of third-party calendar providers. The affected party must notify the other party promptly and take reasonable steps to mitigate the impact.

11. Third-Party Services

CalMesh integrates with third-party calendar providers (Google, Microsoft, Apple, and others) and payment processors (Mollie). Your use of those services is subject to their respective terms. We are not responsible for the availability, accuracy, or conduct of any third-party service.

12. Availability

We aim for high availability but do not guarantee any specific uptime. Scheduled maintenance will be announced where practicable. Business-tier customers receive support with a 48-hour response SLA as described on our pricing page; this is not an uptime SLA.

13. Termination

You may cancel your account at any time via the dashboard or by emailing hello@calmesh.xyz. Upon cancellation, your data will be deleted within 30 days. We may terminate your account for material breach after giving reasonable notice and an opportunity to cure where practicable. Sections 7, 9, 10, 15, and 16 survive termination.

14. Changes to Terms

We may update these terms to reflect changes in law, our services, or business practices. Material changes will be communicated via email at least 30 days before taking effect. Continued use of the service after the effective date requires your active confirmation of the updated terms; silence or inaction does not constitute acceptance. If you do not agree to the updated terms, you may terminate your account before they take effect and receive a pro-rata refund of any prepaid, unused service period.

15. Governing Law & Jurisdiction

These terms are governed by the laws of the Federal Republic of Germany, excluding the UN Convention on Contracts for the International Sale of Goods (CISG).

For merchants (Kaufleute), legal entities under public law, or special funds under public law, the exclusive place of jurisdiction for all disputes arising from or in connection with these terms is Potsdam, Germany.

For consumers, the statutory provisions on jurisdiction apply. Nothing in these terms affects your rights as a consumer under the mandatory consumer protection laws of your country of residence.

16. Severability

If any provision of these terms is held unenforceable, the remaining provisions continue in full force and effect. The unenforceable provision will be replaced by an enforceable provision that most closely reflects the economic intent of the original.
