Terms of service

Last updated: 1 September 2026

These terms govern your use of Puncha, the time tracking service provided by Zest Labs GmbH. By creating an account you agree to them.

1. Acceptance

By registering for, accessing or using Puncha (the "Service") you agree to be bound by these terms. If you register on behalf of a company or another organisation you confirm that you are authorised to bind it, and "you" then means that organisation. You must be at least 16 years old to use the Service.

2. The Service

Puncha lets you record working time against projects, group those projects under clients, define weekly or monthly target hours, take public holidays into account, and review the result. It is available as a web application, and as a command line client that talks to the same API.

3. Accounts

You are responsible for the accuracy of the registration details you provide, for keeping your credentials confidential, and for everything that happens under your account. Tell us without delay at puncha@zestlabs.io if you believe your account has been compromised. Administrators of an organisation can invite, suspend and remove members, and can see the time entries recorded within that organisation.

4. Plans, fees and early access

Puncha is offered in several plans; the plan you choose determines the fees and the features available to you. Fees are stated exclusive of VAT, are billed in advance for the chosen billing period, and are non-refundable for periods already started unless mandatory law says otherwise.

While Puncha is in early access, the prices shown on our website are indicative and may change. We will announce final pricing before general availability and will give account holders at least 30 days' notice by email before any price change takes effect for them. If you do not accept a change you may terminate before it applies.

5. Acceptable use

You agree not to:

  • use the Service in breach of applicable law or third-party rights;
  • attempt to gain unauthorised access to the Service, other accounts, or the infrastructure it runs on;
  • place an unreasonable load on the Service, including through automated requests to the API beyond documented rate limits;
  • resell or make the Service available to third parties outside your organisation;
  • upload content that is unlawful, malicious, or that you are not entitled to process.

We may suspend an account that materially breaches this section, where possible after prior notice.

6. Your data

The clients, projects and time entries you record remain yours. We process them only to provide the Service and as described in our privacy policy. You can export your data at any time while the account is active, and you can ask us to delete it. We may use aggregated, anonymised statistics that cannot be linked to you to operate and improve the Service.

7. Availability

We work to keep Puncha available around the clock, but we do not promise uninterrupted operation. Maintenance windows are announced in advance where practical. No service level agreement applies unless one has been agreed with us in writing.

8. Time records and legal obligations

Puncha is a tool, not legal advice. Public holiday calendars and target hour calculations are provided in good faith, and you remain responsible for meeting any statutory obligation to record working time, and for verifying that the records kept in Puncha satisfy the requirements applicable to you.

9. Term and termination

You may terminate at any time from within the application, with effect at the end of the current billing period. We may terminate a free account with 30 days' notice, and either party may terminate for good cause. On termination your data is deleted in accordance with the retention periods in our privacy policy; export it beforehand.

10. Liability

We are liable without limitation for damages caused intentionally or by gross negligence, for injury to life, body or health, and under the German Product Liability Act. In the case of slight negligence we are liable only for a breach of an essential contractual obligation, and then limited to the foreseeable damage typical for this kind of contract. Any further liability is excluded. You are responsible for keeping your own copies of data that is essential to you.

11. Changes to these terms

We may amend these terms where necessary, for example to reflect new features or legal requirements. Account holders will be notified by email at least 30 days before a change takes effect. Continuing to use the Service after that date counts as acceptance; if you do not accept, you may terminate before the change applies.

12. Governing law and venue

These terms are governed by the law of the Federal Republic of Germany, excluding the UN Convention on Contracts for the International Sale of Goods. Where you are a merchant, a legal entity under public law or a special fund under public law, the exclusive place of jurisdiction is Mannheim, Germany. Mandatory consumer protection provisions of your country of residence remain unaffected.
