Terms of service

App terms

Effective 21 September 2026. Applies to the Renegade Dynamics app for iPhone and Android, the web version at app.renegadedynamics.co.uk, and the relay service. Separate club terms apply to whoever creates or claims a club; separate shop terms apply to anything bought from the shop.

In short.

  • The app is not a safety or navigation device. Look where you are going.
  • You must be at least 13. Recording is free and needs no account.
  • Your recordings are yours. The raw file is free to export, for ever.
  • Subscriptions are billed by Apple or Google and cancelled there. A club subscription is billed by us through Stripe.
  • We do not exclude liability where the law says we cannot.

1. Who we are and what this covers

The app and the service are provided by Jon Davies, trading as Renegade Dynamics, a sole trader in the United Kingdom ("we", "us"). Address for service: Flat 3 Doyle House, 46 Trinity Church Road, London, SW13 8ED. Email: support@renegadedynamics.co.uk.

These terms are the agreement between you and us for the app, the web version and the relay service (together, "the service"). By installing the app, creating an account or using the service you accept them. If you use the service on behalf of a club, the club terms also apply to the club. Our privacy policy explains what we do with personal data and is part of this agreement.

2. Safety

The app is not a safety or navigation device. It does not replace a lookout, a cox's judgement, a coach's judgement, or the rules of the water you are on. Do not watch the screen when you should be watching the river. The crew, the cox, the coach and the club remain responsible for safety on the water at all times.

The numbers the app shows are measurements and estimates from a phone's sensors and, where used, from ours. They can be wrong, late or missing. Position from GPS can be tens of metres out. A live view can stop without warning when the phone loses signal. Do not rely on the app to know where a boat is.

A report or analysis the app produces is information for a coach to weigh, not an instruction to a rower. Any change to training or technique is the coach's and the athlete's decision.

3. Accounts and age

4. Using the app

We give you a personal, non-exclusive, non-transferable licence to install and use the app on devices you own or control, and to use the web version, for your own rowing, coaching or club, in line with these terms. The licence lasts as long as this agreement. Where you got the app from the App Store or Google Play, that store's usage rules also apply, and Apple or Google is not a party to this agreement and has no obligation to you under it.

Some features use your phone's location, microphone, motion sensors or Bluetooth. The app asks for each permission the first time that feature is used and works without the ones you decline, apart from the feature that needs them.

5. Your content and the data promise

6. Audio

Audio is recorded only while the mic switch is on, with a visible indicator, and it is saved on the recording phone. During a live session the audio is relayed to the coaches watching and is not stored by us, unless the recorder chooses at the start to keep it for seven days for the crew and coaches to review the outing, after which it is deleted. The recorder is responsible for making sure the crew know the mic is on. Details are in the privacy policy and in Recording with a cox.

7. Clubs

8. Subscriptions

9. Pre-release software and availability

Parts of the service are new and some are marked beta. We will fix problems as we find them and we ask you to report the ones you meet through "Report a problem" in the app. We do not promise the service will be available at all times; we plan maintenance and tell you where we can, and the status page shows current availability. We may change or withdraw a feature. If we withdraw something you have paid for, we refund the unused part of the subscription.

10. What you may not do

11. Our software and marks

The app, the web version, the relay, the analysis and the designs are ours or our licensors' and stay so. "Renegade Dynamics" and the RNGD mark are our trade marks. The RGIF specification is published under CC BY 4.0 and its reference libraries under MIT or Apache-2.0; those licences, not these terms, govern their use.

12. Liability

Nothing in these terms limits or excludes our liability for death or personal injury caused by our negligence, for fraud, or for anything else that cannot be limited or excluded under the law of England and Wales. If you are a consumer, nothing in these terms affects your rights under the Consumer Rights Act 2015, including the right to a service performed with reasonable care and skill and to digital content that is of satisfactory quality and fit for purpose.

Subject to that:
