Effective date: June 11, 2026
Welcome to FlexChallenge! These terms are intentionally short and readable. By using the app, you agree to them — so please give them a quick read.
By downloading, installing, or using FlexChallenge ("the app"), you agree to these Terms of Service. If you don't agree, please don't use the app.
We grant you a personal, non-exclusive, non-transferable, revocable license to use FlexChallenge on Apple devices that you own or control, in accordance with these terms and Apple's App Store rules. You may not copy, modify, reverse-engineer, resell, or redistribute the app except where the law expressly allows it.
Everything you create in FlexChallenge — challenges, photos, videos, voice notes, daily notes, and all other data — belongs to you. All of it is stored locally on your device; we never receive, access, or claim any rights to it. You're responsible for backing it up (the app includes a built-in export feature for exactly this).
FlexChallenge is a habit and challenge tracker. It is not medical advice, and it is not a substitute for professional medical guidance.
Use the app lawfully and sensibly. Don't:
FlexChallenge is currently free, with full access to all features. No purchase is required.
We may introduce optional auto-renewable subscriptions in the future. If and when subscriptions are offered, the following will apply:
Nothing about a future subscription will change our privacy practices: your data stays on your device.
The app is provided "as is" and "as available", without warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, and non-infringement. We don't guarantee the app will be error-free, uninterrupted, or that tracked data (like step counts) will be accurate.
To the maximum extent permitted by law, we are not liable for any indirect, incidental, special, consequential, or punitive damages — including lost data, lost profits, or personal injury — arising from your use of (or inability to use) the app. Where liability cannot be excluded, our total liability is limited to the amount you paid for the app in the twelve months before the claim (which, while the app is free, is zero).
Some jurisdictions don't allow certain limitations, so parts of this section may not apply to you.
Because all data is stored on your device, you are responsible for safeguarding it. Use the in-app backup export before deleting the app or switching devices — deleting the app permanently removes all app data from your device, and we cannot recover it for you (we never had a copy).
Where these terms do not say otherwise, Apple's standard Licensed Application End User License Agreement (EULA) applies to your use of FlexChallenge: apple.com/legal/internet-services/itunes/dev/stdeula. Apple is not a party to these terms and is not responsible for the app or its content, but Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them.
These terms are governed by the laws of the State of Arizona, United States, without regard to conflict-of-law principles.
We may update these terms from time to time. When we do, we'll update the effective date above and, for material changes, give notice in the app or in App Store release notes. Continued use of the app after changes take effect means you accept the updated terms.
