Ceyu

Terms of service

Last updated: 28 July 2026

1. Who this is between

These terms govern your use of the Ceyu applications and services, provided by Larisa Schlosser, 16 Erlenhain, 88480 Achstetten, Germany (“we”, “us”). “You” means the person or organisation using the service.

German law applies. If you are a consumer, the mandatory consumer-protection provisions of your country of residence continue to apply and nothing here overrides them.

2. The service

Ceyu provides a visual whiteboard and a project planning suite, as desktop applications for Windows and macOS and in the browser, with optional cloud sync, real-time collaboration, imports, exports, templates and opt-in AI-assisted features.

The scope of what is included depends on your plan. The pricing page is authoritative on that.

3. Who may use Ceyu

You must be at least 18 years old to create an account or accept these terms. Ceyu is a professional tool and is not directed at children.

If you are between 16 and 18, you may only use Ceyu through an account held by an organisation, with the permission of a parent or guardian who accepts these terms on your behalf. Below 16 the service may not be used at all.

We do not knowingly accept accounts from minors. If we learn that one exists, we close it and delete the associated personal data — see section 9 of the privacy policy. If you are a parent or guardian and believe your child holds an account, write to privacy@ceyu.org.

Where you accept these terms on behalf of a company, you confirm that you are authorised to bind it.

4. Accounts and organisations

  • You must give accurate account information and keep your credentials secure.
  • You are responsible for activity under your account.
  • Organisation owners and administrators are responsible for inviting users, assigning roles, managing SSO or directory sync, and configuring enterprise controls.

We may suspend an account, an organisation or a feature where necessary to protect the service, other users, tenant separation, payment integrity or legal compliance. Where circumstances allow, we tell you first.

5. Plans, prices and billing

Paid plans are subscriptions, billed monthly or yearly in advance, per user. Displayed prices are the total price including VAT, as required for consumers by the German Price Indication Ordinance (PAngV). Business customers can enter a VAT ID at checkout; the VAT is then removed under the reverse-charge procedure and the net price applies.

Creem acts as merchant of record. They process payment, issue the invoice and handle tax. Your contract for the payment transaction is with them; your contract for the service is with us.

  • Subscriptions renew automatically for the same period unless cancelled before the end of the current one.
  • Upgrades take effect immediately and are charged pro rata.
  • Downgrades take effect at the next renewal.
  • Cancellation ends the renewal; it does not shorten a period already paid for.

Refunds are covered by the refund policy. Consumers in the EU additionally have the statutory right of withdrawal.

5.1 The trial

The Pro yearly plan starts with a 7 day trial. No other plan includes one: Plus and Studio, and every monthly plan, are charged at checkout.

The trial converts automatically into the paid Pro yearly plan at the end of the seven days unless you cancel before then. You can cancel at any point during the trial from your customer portal, which is linked in every order email, and you will not be charged.

Because the service begins during the withdrawal period, we ask you at checkout to confirm two things separately: that you expressly want performance to start immediately, and that you understand this ends your statutory right of withdrawal once performance is complete (§ 356 (5) BGB). Neither confirmation is pre-ticked. The 14 day money-back guarantee in the refund policy applies regardless.

5.2 The free plan

The Basic plan is free and has no expiry date. We may change its limits with reasonable notice. It is provided as-is, and the availability commitments below do not apply to it.

6. Your content

You keep ownership of everything you put into Ceyu. We claim no rights in your boards, tasks, assets or any other content.

You grant us a limited licence to host, store, transmit, back up and display that content strictly to the extent needed to operate the service for you — for example, to sync it between your devices or show it to a collaborator you invited. The licence ends when the content is deleted.

You are responsible for having the rights to the material you upload. Where cloud sync is enabled, content is encrypted on your device and we cannot read it.

6.1 Feedback

If you send us suggestions, we may use them to improve the product without obligation or payment. This does not apply to your content.

7. Acceptable use

The acceptable use policy forms part of these terms. In short: do not use Ceyu for anything unlawful, do not attack the service or other tenants, and do not resell it as your own.

8. Availability

We aim for high availability but do not promise uninterrupted service on the standard plans. Maintenance, third-party failures and events outside our control can cause downtime.

Contractual availability commitments exist only where an Enterprise agreement with an SLA has been signed.

Because Ceyu is local-first, a service outage does not take your work away: your boards remain on your own disk and remain editable offline.

8.1 Changes to the service

The product develops. We may add, change or remove features. Where we remove a feature that materially affects a paid plan you are on, we give reasonable advance notice, and you may cancel and receive a pro-rata refund for the unused remainder.

Nothing on the roadmap is a contractual commitment unless it is described as shipped.

9. Warranty and liability

We are liable without limitation for damages arising from injury to life, body or health, from intent or gross negligence, and under the German Product Liability Act.

For slight negligence, we are liable only where a material contractual obligation is breached — an obligation whose fulfilment makes proper performance possible in the first place and on which you may routinely rely — and then only up to the foreseeable damage typical for this kind of contract.

Any further liability is excluded. This does not reverse the burden of proof to your disadvantage, and statutory consumer rights are unaffected.

9.1 Backups

We keep server-side backups as described in the privacy policy. They are for our operational recovery and are not a substitute for your own. Keep your own copies of work that matters — local-first storage makes this straightforward.

10. Term and termination

  • You can cancel a subscription at any time, effective at the end of the current period.
  • You can delete your account at any time; see data requests.
  • We may terminate for material breach of these terms or the acceptable use policy, after notice where the breach can be remedied.

After termination, content is soft-deleted and then purged according to the retention schedule. Export your data first if you want it — and note that the local copies on your own machines are unaffected either way.

11. Changes to these terms

We may change these terms where there is a valid reason, such as a change to the service or to the law. Existing customers are notified at least 30 days in advance by email or in the application. If you do not accept the change, you may terminate before it takes effect.

12. Final provisions

Place of jurisdiction is Germany, to the extent permitted by law. If a provision of these terms is or becomes invalid, the remainder stays in force. There is no obligation to participate in proceedings before a consumer arbitration board; the EU online dispute resolution platform is linked in the imprint.
