Terms of Use

These terms are the agreement between you and Michal Kos ("we", "us") for the NoJar iOS app and this website. Installing or using the app means you accept them. If you do not, do not use the app.

Apple's Licensed Application End User Licence Agreement also applies to your download. Where it and these terms conflict, Apple's terms win for anything to do with the App Store itself.

1. Licence

We grant you a personal, non-exclusive, non-transferable licence to use NoJaron Apple devices you own or control, as permitted by the App Store terms. You may not resell it, rent it, reverse engineer it beyond what the law allows, or strip out its notices.

The app, its design, its copy and its curated prompt library remain ours. What you write in the app — your asks, notes and outcomes — remains entirely yours, and we claim no rights in it because we never receive it.

2. Purchases and refunds

• The free tier logs 10 asks. A single one-time purchase unlocks the rest of the app. There is no subscription and no recurring charge.
• All purchases are processed by Apple. Prices shown in the App Store include the taxes Apple applies for your region and may differ between regions.
• Refunds are handled by Apple, not by us. Request one at reportaproblem.apple.com. We cannot issue, deny or override an App Store refund.
• The unlock is tied to your Apple Account and can be restored on your devices from Settings → Restore purchase.
• A refund removes the unlock. Your logged data stays on your device either way.

3. Your data

Everything you log stays on your device. We hold no copy, which also means we cannot recover anything for you. If you delete the app, delete an ask, or lose the device without a backup, that data is gone. Export a CSV from Settings if it matters to you.

How data is handled is described in the Privacy Policy, which forms part of these terms.

4. What the app is, and is not

• NoJar is a self-tracking tool. It is not medical advice, psychological treatment, or a substitute for care from a qualified professional. If asking people for things causes you real distress, please speak to one.
• The calibration figures describe your own logged data and nothing more. The asks you choose are not a random sample, so your observed yes rate is not a measurement of people in general, and the app says so on the same screen.
• Research findings referred to on this site are cited as published research, not as predictions about what will happen to you.
• Outcomes are what you type in. The app cannot verify them, and its output is only as honest as your logging.

5. Acceptable use

You are responsible for what you ask for and how you ask. Do not use the app in connection with harassment, deception, coercion, or pressure on anyone who is not free to decline — including people at work whose job makes refusing costly. The prompt library is curated to exclude that, and the same standard applies to your own asks. You must also comply with the law where you are.

6. Availability and changes

The app runs on iOS 26 and later. We may update it, change features, or stop distributing it. We will not remove your ability to read and export data you have already logged in a version you have installed.

7. Warranty and liability

The app is provided "as is", without warranties beyond those that cannot be excluded by law. To the extent the law allows, we are not liable for indirect or consequential loss, for lost data, or for anything that follows from an ask you chose to make. Our total liability is limited to the amount you paid for the app.

Nothing here limits your statutory consumer rights. If you are a consumer in the EU, those rights apply in full regardless of anything above.

8. Governing law

These terms are governed by the law of the Czech Republic. If you are a consumer, you keep the protection of the mandatory law of the country you live in, and may bring proceedings there.

9. Changes to these terms

We may revise these terms; the updated date at the top will change. Continuing to use the app after a revision means you accept it. Material changes will be noted in the App Store release notes.
