Terms (EULA)
End User License Agreement
Last updated · August 2026
This End User License Agreement (“Agreement”) governs your license to use the Rungeist macOS application and its widget (the “Software”). That license is granted by the operator listed in the imprint (Dustin Deunert – deunert.io). The purchase itself is a separate contract, concluded with Polar as merchant of record and seller, under Polar’s buyer terms. In short: you buy from Polar, and you license the Software from us. By installing, activating or using the Software you agree to this Agreement.
1. License & trial
The Software runs fully featured for a 7-day free trial (no account, no card). It is then sold as a one-time purchase of €19.99, granting a non-exclusive, perpetual license to install and use the purchased version, together with any updates we make available at our discretion, on up to two (2) Macs you own or control — subject to any mandatory statutory obligation to provide updates, including necessary security updates. This is not a promise of future feature updates or of any particular feature-update period. Activation registers each Mac with our license provider (Polar) against that limit; you can free a slot with Deactivate This Mac in Settings.
2. What you may not do
Except where mandatory law provides otherwise, you may not redistribute, resell, rent, sublicense or share the Software — including the application bundle, the disk image (.dmg) it is distributed in, and any update package — or your license key; circumvent the trial, activation or license checks, except to the extent such acts are permitted by mandatory law (in particular §§ 69d, 69e UrhG); or use the Software unlawfully. Rungeist is proprietary software; all rights reserved. Third-party open-source components remain under their own licenses and are listed in the app under Settings → General → Acknowledgements.
3. Process termination — important
The Software can terminate processes on your Mac (it sends SIGTERM to a server’s process group) and can stop, force-stop or restart Docker containers visible to the docker CLI on your Mac — including containers started by other tools — via docker stop/kill/restart. This can cause unsaved work, running services, or container state to be lost or interrupted. You are responsible for choosing what to terminate. To the maximum extent permitted by law, we are not liable for data loss or interruption resulting from terminating a process or container (see sections 6–7).
4. Price, payment & merchant of record
The Software is sold through Polar as merchant of record. Polar is the seller for the transaction and handles payment, invoicing and any applicable VAT/sales tax. Prices shown to consumers are gross prices including VAT.
5. Refunds & right of withdrawal
If you are a consumer, you may have a statutory right to withdraw within fourteen days, subject to the law that applies to you and to any statutory exceptions. In the EU/EEA/UK such a right generally exists for digital purchases. At checkout you are asked to consent expressly to immediate delivery and to acknowledge that this statutory right ends once delivery begins — so where it exists, it can lapse as soon as the Software is made available to you. Independently of that, we give you 14 days to change your mind. This is our own promise, not a statutory one, and it applies wherever you live. If you change your mind within 14 days of purchase, contact info@rungeist.com or Polar and we will arrange a refund. Refunds are processed by Polar as merchant of record. The Software is also free to evaluate for 7 days before any purchase.
The formal instruction, including how to declare a withdrawal and a model withdrawal form, is on the right of withdrawal page.
6. Your statutory rights, and what we do not warrant
Nothing in this Agreement limits or excludes your statutory rights. If you are a consumer, those include the mandatory rights that apply to digital products — covering the conformity, functionality and security of the Software, and any updates the law requires us to provide. They apply regardless of anything written here.
Subject to those rights, and to the maximum extent the law allows: we do not warrant that the Software runs uninterrupted or error-free, that it identifies every server, or that it terminates processes exactly as intended.
7. Limitation of liability
We are liable without limitation for intent, gross negligence, injury to life, body or health, under any guarantee we give, and under mandatory product-liability law. For slight negligence we are liable only for breach of a material contractual obligation, and then only for foreseeable, contract-typical damage. All other liability is excluded — in particular for loss of data or work from terminating a process. Nothing in this Agreement limits any rights that cannot be excluded under the law applicable to you.
8. Updates
The Software checks for updates automatically using the Sparkle framework, once a day by default, and offers any new version for installation; it is installed only after you confirm. In the update dialog you can opt in to having future updates downloaded and installed automatically. What the check transmits is described in the privacy policy.
9. Governing law & contact
This Agreement is governed by the laws of the Federal Republic of Germany (excluding the CISG); mandatory consumer law of your country of residence still applies. Contact: info@rungeist.com.
