Terms of Use

Turnella (“Turnella”, “we”, “us”, “our”) is an independent service operated within the European Union. All rights in and to the Service — including the website, web application, user interface, source code, algorithms, documentation, calculators, knowledge content, brand name, logo, and other materials — are and remain the exclusive property of Turnella. See our Legal Notice for operator and contact details.

Nothing in these Terms grants you any ownership interest or intellectual property rights in the Service.

Subject to these Terms, Turnella grants you a limited, non-exclusive, non-transferable, revocable licence to access and use the Service for your own legitimate business planning purposes or to evaluate Turnella as a prospective user.

You may:

• Create an account and use the planning tools for your own operational planning
• Access and read the documentation and use the free calculators
• Export your own data using the export features provided

You may not:

• Copy, scrape, reproduce, or redistribute any part of the Service or its content
• Reverse engineer, decompile, disassemble, or attempt to derive the source code or underlying algorithms
• Resell, sublicense, or otherwise transfer access to the Service to third parties
• Use the Service or its content (including calculators, documentation, or UI design) to build a competing or substantially similar product or service
• Use automated tools, bots, or scrapers to collect data from the Service at scale
• Use the Service in any way that violates applicable laws or regulations
• Share account credentials or allow others to use your account
• Attempt to circumvent any security measures or access areas of the Service you are not authorised to access

The Service — including all calculators, documentation, benchmarks, templates, worked examples, and content — is provided for informational and planning purposes only. It is not a substitute for professional advice.

Turnella does not provide legal, HR, employment law, financial, compliance, medical, or other professional advice. Nothing in the Service should be relied upon as such. Always consult qualified professionals for decisions affecting your organisation.

In particular, the staffing models (Erlang C, concurrency, backlog models) and all output figures are estimates based on the assumptions and data you provide. They are tools to support decision-making, not guarantees of operational outcomes.

Turnella is currently in early access. Features, calculations, interfaces, and availability may change at any time without notice. We aim to give reasonable advance notice of material changes where possible, but cannot guarantee uninterrupted service or that any specific feature will remain available.

Turnella is currently free to use during early access. We may introduce paid plans, or change pricing, in the future. Where we do, we will give reasonable notice, and the terms of any paid plan will be made clear before it applies to you.

Planning data, historical records, configurations, and other content you enter into Turnella remains your data. You retain all rights to it.

By using the Service, you grant Turnella a limited licence to store, process, and display your data solely for the purpose of providing the Service to you. Turnella does not claim ownership of your data and does not use it for purposes other than those described in the Privacy Policy.

Rostering and employee data. If you use the roster features, you may enter personal data about third parties — your employees, contractors, or other team members (names, roles, contracted hours, availability, time-off entries, shift assignments, and skill tags). When you do so:

• You act as the data controller for that employee data. Turnella acts as a data processor on your behalf, storing and making available only what you enter, in line with our Data Processing Addendum.
• You are responsible for ensuring you have a valid lawful basis under applicable data-protection law (such as the GDPR or UK GDPR) to enter and process your employees’ personal data in Turnella, and for providing any required notice to those individuals.
• Enter only the minimum personal data necessary for workforce planning purposes. Do not enter medical details, health information, disciplinary records, or other special-category personal data anywhere in the Service.
• Turnella is a planning tool, not an HR system of record. It does not have features for managing employment contracts, payroll, or legally required HR documentation.

You are responsible for ensuring that any data you enter does not violate applicable laws or third-party rights.

Turnella uses third-party services for hosting, authentication, analytics, AI features, and other infrastructure. These include Supabase, Vercel, and Anthropic (for optional AI features). Use of the Service is subject to the applicable terms and privacy policies of these third parties.

Turnella is not responsible for the performance, availability, or conduct of third-party services.

Turnella is provided “as is” and “as available” without warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, or non-infringement.

We do not guarantee that the Service will be available at all times, free from errors or interruptions, or that any specific feature will continue to function as expected.

To the maximum extent permitted by applicable law, Turnella shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of revenue, data, or business, arising from your use of or inability to use the Service — even if Turnella has been advised of the possibility of such damages.

These Terms are governed by the laws applicable in the European Union jurisdiction in which Turnella is established. Any dispute relating to these Terms or the Service will be subject to the competent courts of that jurisdiction, without prejudice to any mandatory consumer-protection rights you may have under the law of your country of residence.

We may update these Terms from time to time. When we do, we will revise the “last updated” date above. Continued use of the Service after changes take effect constitutes acceptance of the updated Terms.
