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.
These terms cover both the FlexChallenge app and the flexchallenge.app website. The website uses analytics and advertising cookies (Google Analytics and the Meta Pixel); how they work and how to opt out is described in our Privacy Policy.
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 a paid app that requires an auto-renewing subscription. After a short introduction in which you build your first challenge, you must subscribe before you can start and track it.
One subscription unlocks every feature. There are no tiers, no additional in-app purchases, and no ads.
Prices shown are for the United States App Store. Prices in other regions are set by Apple's regional pricing and are always displayed in your local currency inside the app before you buy. The price displayed in the app at the moment of purchase is the price that governs.
New subscribers who have never previously subscribed to FlexChallenge are eligible for a 14-day free trial on either plan. Eligibility is determined by Apple, not by us, and is tied to your Apple Account and its subscription history. If you are not eligible, the app will not offer or display a trial, and your subscription begins as a paid subscription immediately.
Subscriptions renew automatically. Unless you cancel, your subscription renews at the end of each billing period and continues until cancelled.
You can view, change, or cancel your subscription at any time in iOS Settings → [your name] → Subscriptions → FlexChallenge.
Cancelling turns off future renewals. You keep full access through the end of the period you have already paid for. Deleting the app does not cancel your subscription — you must cancel through iOS Settings.
All refunds are handled by Apple, not by us. We cannot issue, process, or reverse a charge for an App Store subscription. To request a refund, use Apple's process at reportaproblem.apple.com or contact Apple Support. Refunds are granted at Apple's discretion under the App Store's terms. Except where required by law, subscription fees are non-refundable, and cancelling partway through a billing period does not entitle you to a prorated refund.
If your subscription ends and is not renewed, FlexChallenge shows a resubscribe screen and the app's features — including viewing your challenges, history, photos, and statistics — are not accessible until you resubscribe. Your data is not deleted: it remains stored on your device exactly as you left it, and it returns intact when you resubscribe. If you do not intend to resubscribe, export a backup before your subscription lapses using the in-app backup feature, because deleting the app permanently removes that data and we hold no copy of it.
If FlexChallenge cannot reach the App Store to verify your subscription (for example, you are offline), the app allows continued access for a short grace period before requiring verification.
If you reinstall the app or set up a new device signed in to the same Apple Account, tap Restore Purchases on the paywall to recover your active subscription. You are never asked to pay twice for the same subscription.
We may change subscription prices, introduce new plans, or change what a plan includes.
Subscribing does not change our privacy practices: your challenge data stays on your device. See the Privacy Policy for what purchase information Apple and our subscription-management provider receive.
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 us for the app in the twelve months before the claim.
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, switching devices, or letting a subscription lapse — 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.
