Terms of Service
CalDAVconnect – calendar synchronization service
Mediakreativ UG (haftungsbeschränkt)
§ 1 Scope
(1) These General Terms and Conditions (hereinafter "Terms") govern use of the calendar synchronization service CalDAVconnect (hereinafter "Service"), operated by Mediakreativ UG (haftungsbeschränkt), Herrengasse 2, 06542 Allstedt (hereinafter "Provider").
(2) The Terms apply to all users of the Service (hereinafter "User"), regardless of the plan selected.
(3) The User's conflicting terms shall not apply unless the Provider expressly agrees to them in writing.
§ 2 Service Description
(1) CalDAVconnect enables bidirectional synchronization of calendar entries between CalDAV servers (e.g. Nextcloud, SOGo, Radicale, Baikal, Synology, Infomaniak, mailbox.org, Posteo, Fastmail) and cloud calendar platforms (Google Calendar, Microsoft 365).
(2) The Service synchronizes calendar entries from the last 90 days and all future entries. Older entries remain on the respective CalDAV server.
(3) The Provider provides the Service as software as a service (SaaS). The User receives a non-exclusive, non-transferable right to use the Service for the duration of the contractual relationship.
(4) The Provider endeavors to ensure Service availability of 99 % on an annual average. Excluded from this are scheduled maintenance periods and disruptions outside the Provider's sphere of influence (e.g. outages at Google, Microsoft, or the User's CalDAV server).
§ 3 Contract and Registration
(1) The contract is concluded when the User registers and confirms their email address. By registering, the User accepts these Terms, the Privacy Policy, and the Data Processing Agreement (DPA) pursuant to Art. 28 GDPR.
(2) The User undertakes to provide truthful information when registering and to keep their login credentials confidential.
(3) The User must be of legal age and have capacity to contract. If use is within a business context, the registering person must be authorized to represent the entity.
§ 4 Plans and Pricing
(1) The Service is offered under the following plans:
| Plan | Price | Service |
|---|---|---|
| Free | €0 / month | 1 connection, hourly sync interval |
| Solo | €2 / month | 1 connection, sync within seconds |
| Pro | from €5 / month | 5 connections, sync within seconds; higher tiers: Pro 10 (10 connections) for €8 / month, Pro 15 (15 connections) for €11 / month |
(2) All prices include applicable statutory VAT.
(3) The Provider may offer time-limited free trials of paid plans. After a trial ends, the plan does not automatically continue as a paid plan; a paid subscription is only concluded through a separate order placed by the User.
(4) The Provider reserves the right to adjust prices with 30 days' notice. Existing contracts remain unaffected until the end of the respective billing period.
§ 4a Founder Plan (Lifetime Pro)
(1) The Provider grants selected beta testers who actively provided constructive feedback during the beta phase (hereinafter "Founders", meaning early supporters of the beta phase) the Pro plan free of charge on a permanent basis ("Founder Plan"). Founder classification is made by the Provider; there is no legal entitlement to inclusion.
(2) "Permanently free" refers to the lifetime of the CalDAVconnect Service, not the lifetime of the User. The Founder Plan ends if the Provider discontinues the Service as a whole. The Provider will announce any discontinuation of the Service with at least 90 days' notice.
(3) The Founder Plan comprises the Pro plan in its respective current feature scope (currently 5 connections, sync within seconds). If the Founder needs more connections, they may switch to a higher Pro tier; the Founder discount is applied to the respective tier price (currently Pro 10 for €3/month, Pro 15 for €6/month). Future, separately priced features or standalone new products are not automatically included in the Founder Plan.
(4) The Founder Plan is personal, bound to the respective user account or the email address on file, and is non-transferable, non-assignable, and non-resellable. Founder status is granted only once per user account.
(5) The Founder Plan requires an existing, active user account and is subject to the obligations under § 7. In the event of abusive use or a serious or repeated breach of these Terms, the Provider may revoke the Founder Plan in accordance with § 10.
(6) The Provider reserves the right to adjust the feature scope or usage limits of the Pro plan for good cause (e.g. significant changes in the costs of third-party interfaces) with reasonable notice. This does not affect the free provision of the Pro base plan for Founders.
§ 5 Payment Terms
(1) Paid plans are billed monthly in advance. The billing period begins when the paid plan is concluded and automatically renews for one month at a time until the contract is terminated.
(2) Payment is processed via the payment service provider Stripe (Stripe Payments Europe, Ltd., 1 Grand Canal Street Lower, Dublin 2, Ireland). Stripe's terms apply in addition. The Provider does not store full payment instrument data (e.g. card numbers); these are processed exclusively by Stripe. Details on data processing are set out in the Privacy Policy.
(3) Invoices are provided electronically and can be accessed at any time via the Stripe customer portal.
(4) In case of default, the Provider may, after unsuccessful reminder, restrict access to the Service to the feature set of the Free plan.
§ 6 Right of Withdrawal for Consumers
(1) Consumers have a statutory right of withdrawal for paid contracts. A consumer is any natural person who concludes the contract for purposes that are predominantly outside their trade, business, or profession (§ 13 German Civil Code, BGB).
(2) The Provider informs about the right of withdrawal as follows:
Withdrawal Instructions
Right of withdrawal
You have the right to withdraw from this contract within fourteen days without giving any reason. The withdrawal period is fourteen days from the day of conclusion of the contract.
To exercise your right of withdrawal, you must inform us (Mediakreativ UG (haftungsbeschränkt), Herrengasse 2, 06542 Allstedt, email: hello@caldavconnect.de) of your decision to withdraw from this contract by means of a clear statement (e.g. a letter sent by post or an email). You may use the model withdrawal form below, but it is not mandatory.
To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.
Consequences of withdrawal
If you withdraw from this contract, we shall reimburse all payments received from you without undue delay and no later than fourteen days from the day on which we receive notification of your withdrawal from this contract. For this reimbursement, we will use the same means of payment that you used for the original transaction, unless expressly agreed otherwise with you; in no case will you be charged any fees because of this reimbursement.
If you requested that the service should begin during the withdrawal period, you shall pay us a reasonable amount corresponding to the proportion of the services already provided up to the point in time at which you notify us of the exercise of the right of withdrawal with regard to this contract, compared with the total scope of the services provided for in the contract.
(3) Expiry of the right of withdrawal: For a contract for the provision of services, the right of withdrawal expires if the Provider has fully performed the service and only began performing the service after the consumer gave their express consent and at the same time confirmed their awareness that they lose their right of withdrawal upon complete performance of the contract by the Provider (§ 356 (4) BGB). The User gives this consent and acknowledgment during the ordering process by expressly ticking the corresponding statement.

§ 7 User Obligations
(1) The User is responsible for the accuracy of the login credentials they enter (CalDAV server, Google Calendar, Microsoft 365).
(2) The User ensures they are entitled to process the calendar data to be synchronized. In particular, where calendars contain personal data of third parties (e.g. participant names, patient data), data protection responsibility lies with the User.
(3) The User undertakes not to misuse the Service, in particular not:
- for automated mass querying of API endpoints
- to forward or sell synchronized data to third parties
- in a manner that impairs operation of the Service or third parties
(4) The User must keep their login credentials secret and inform the Provider without delay if they become aware of unauthorized access to their account.
§ 8 Data Protection
(1) The Provider processes the User's personal data in accordance with the Privacy Policy.
(2) The Provider processes calendar data on behalf of the User. The Data Processing Agreement (DPA) pursuant to Art. 28 GDPR applies. The DPA forms part of this contract and is accepted upon registration. Upon request, the Provider will provide the DPA as a signed document.
(3) All data are processed and stored exclusively on servers within the European Union (Hetzner Online GmbH, Germany).
(4) Calendar content, credentials, and OAuth tokens are stored encrypted with AES-256-GCM.
§ 9 Warranty and Liability
(1) The Provider has unlimited liability for damages arising from injury to life, body, or health resulting from intentional or negligent breach of duty, and for damages resulting from intentional or grossly negligent conduct.
(2) In case of slight negligent breach of essential contractual obligations (cardinal obligations), the Provider is liable for typical, foreseeable contract damages.
(3) Further liability of the Provider is excluded. This applies in particular to:
- data loss caused by errors of the CalDAV server, Google, or Microsoft
- synchronization errors due to network disruptions or third-party API changes
- damages from rescheduled or lost appointments due to faulty synchronization
(4) The Provider is not liable for the availability or functionality of the User's CalDAV servers or the services of Google and Microsoft.
(5) The limitations of liability also apply in favor of the Provider's vicarious agents.
§ 10 Contract Duration and Termination
(1) The contract is concluded for an indefinite term.
(2) The User may terminate a paid plan at the end of the current billing period, in particular via the Stripe customer portal or by deleting the user account. On the Free plan, immediate termination is possible. The statutory right of withdrawal under § 6 remains unaffected.
(3) Termination is effected by deleting the user account in account settings or by email to hello@caldavconnect.de.
(4) The Provider may terminate the contract with 30 days' notice. The right to extraordinary termination for good cause remains unaffected, in particular in cases of:
- serious or repeated breach of these Terms
- abusive use of the Service
- default on payment despite reminder
(5) Upon termination, all User data will be deleted in accordance with the Privacy Policy and the DPA.
§ 11 Changes to Terms
(1) The Provider reserves the right to amend these Terms with effect for the future.
(2) The Provider will inform the User of changes by email. If the User does not object within 30 days of receipt of the change notice, the amended Terms shall be deemed accepted.
(3) The Provider will inform the User in the change notice of the objection period and the consequences of silence.
(4) In the event of an objection, both parties have a special right to terminate.
§ 12 Final Provisions
(1) The law of the Federal Republic of Germany applies to the exclusion of the UN Convention on Contracts for the International Sale of Goods.
(2) Place of performance and exclusive venue for all disputes arising from this contract is Allstedt, insofar as the User is a merchant, a legal entity under public law, or a special fund under public law, or has no general place of jurisdiction in Germany.
(3) Should individual provisions of these Terms be or become invalid, this shall not affect the validity of the remaining provisions.
(4) The EU Online Dispute Resolution (ODR) platform was discontinued on 20 July 2025 (Regulation EU 2024/3228). A list of consumer dispute resolution bodies in the EU Member States is available at consumer-redress.ec.europa.eu. The Provider is neither willing nor obliged to participate in dispute resolution proceedings before a consumer arbitration body.
