Terms of use
Short and plain, because there is not much to it. Quality Days is a single-developer iPhone app with no account and no service behind it. Using it means you accept what follows.
What you get
You get a personal, non-transferable licence to use Quality Days on Apple devices you own or control, for as long as you keep it installed. The app and its contents stay the property of the developer. You may not sell it, rent it, decompile it or pull it apart to build something from it, except where the law says you may regardless of this paragraph.
This is not medical advice
Quality Days is a training tool, not a medical device. It reads figures your iPhone and watch recorded and does arithmetic on them. Nothing it shows is a diagnosis, a health assessment, or advice about whether you should train, rest, race or see a doctor.
Training plans in the app are published marathon schedules, generic by definition, written for nobody in particular. Paces, loads and thresholds are estimates derived from your own past runs and they can be wrong. Use your judgement, and talk to a qualified professional before starting or changing a training programme, especially if you have a health condition, are recovering from injury, or are new to running. If something feels wrong while you are running, stop.
Accuracy
Every number in the app comes from Apple Health, which in turn gets it from your iPhone, your watch, or whatever app wrote it there. GPS drifts, heart-rate straps slip, watches miss samples, and a workout recorded twice will look like two workouts until the app merges it. Forecasts come from Apple WeatherKit and are forecasts. The app does not promise any of it is right, and you should not rely on it for anything that matters more than a training decision.
No warranty
The app is provided as is and as available, without warranty of any kind, express or implied, including any implied warranty of merchantability, fitness for a particular purpose, accuracy or non-infringement. There is no promise that it will be uninterrupted, error free, compatible with a future version of iOS, or that any particular feature will keep working or keep existing.
Limits on liability
To the fullest extent the law allows, the developer is not liable for any indirect, incidental, special or consequential loss arising from your use of the app, including injury, lost data, lost time or a race that did not go the way you hoped. Some jurisdictions do not allow limits like this, in which case the limit applies as far as it legally can and no further, and nothing here affects rights you have as a consumer that cannot be waived.
The Apple licence
Quality Days is distributed through the App Store. Unless the developer supplies a separate, custom licence agreement, the app is licensed to you under Apple's Licensed Application End User License Agreement, the standard EULA, and these terms sit alongside it. Where the two disagree, the Apple standard EULA governs for anything it covers.
Three things worth pulling out of it. The licence is between you and the developer, not you and Apple. Apple has no obligation to provide support or maintenance for the app. And Apple and its subsidiaries are third-party beneficiaries of that agreement, which means Apple may enforce it against you.
Your data
The app holds your data on your device and sends none of it anywhere. That is described properly in the privacy policy, which is part of these terms.
Changes and ending it
These terms may change as the app does. The effective date above will change with them, and continuing to use the app after that means you accept the new version. You can end this agreement whenever you like by deleting the app, which also deletes everything it held.
