Terms of Use
Last updated: November 13, 2026
1. Acceptance
By downloading or using 30 Day Challenges you agree to these terms. If you got the app from the Apple App Store, Apple's Standard Licensed Application End User License Agreement also applies; where they conflict, Apple's EULA wins.
2. Your health comes first
Many challenges are physical (push-ups, running, plank and so on). The app is a tracker and motivator, not medical or fitness advice. Check with a doctor before starting a challenge if you have a health condition, an injury, are pregnant, or haven't exercised in a while. Stop if something hurts. Catch-up can raise a day's target; it's optional, and skipping or resting is always fine. Amounts filled in from Apple Health are only as accurate as the data your devices recorded.
3. Your account
You need an account to use the app. Keep your password safe; you're responsible for what happens in your account. You can delete it at any time in the app (You → Delete account). How we handle your data is described in the privacy policy.
4. Free plan and Premium
- Free: up to 5 challenges running at once and one friends group at a time, with ads on iPhone, iPad and Android. Your history and all logging stay free.
- Premium adds unlimited running challenges, no ads, every app colour, the detailed day-by-day chart, more than one friends group, and Apple Health on iPhone.
5. Premium subscriptions
- Premium is an auto-renewing subscription, billed monthly or yearly. The price and length of each plan are shown in the app before you buy.
- Premium is sold only through the Apple App Store and Google Play. Payment is charged to your Apple ID or Google account when you confirm the purchase.
- The subscription renews automatically at the same price and length unless you turn off auto-renew at least 24 hours before the end of the current period. Your account is charged for the renewal within the 24 hours before the period ends.
- To cancel: on iPhone or iPad, open Settings → your name → Subscriptions → 30 Day Challenges → Cancel Subscription. On Android, open Google Play → your profile picture → Payments & subscriptions → Subscriptions → 30 Day Challenges → Cancel subscription. Cancel at least 24 hours before renewal; Premium stays on until the end of the period you've paid for. Deleting the app or your account doesn't cancel the subscription.
- Refunds are handled by the store under its own policy: Apple at reportaproblem.apple.com, Google through Google Play's refund options. We can't issue refunds ourselves.
- Use Restore purchases on the Premium screen to turn Premium on again on a new device signed in to the same store account.
6. Ads
The free plan on iPhone, iPad and Android shows ads served by Google AdMob. We don't control the content of individual ads, and what you do on an advertiser's site is between you and them.
7. Challenges with friends
Group names and the names you use are visible to everyone in the group. Don't use names that are offensive or impersonate someone. We may remove groups or accounts that misuse the app.
8. Licence
We grant you a personal, non-exclusive, non-transferable licence to use the app on devices you own or control. You may not decompile, reverse engineer or redistribute it.
9. Reminders and availability
Reminders depend on your device's notification settings, battery-saving modes and operating system, so we can't guarantee they arrive at an exact time. Syncing needs an internet connection; we aim to keep the service running but can't promise it will always be available.
10. Disclaimer and liability
The app is provided "as is" without warranties of any kind. To the extent permitted by law, Kynetics BSD is not liable for indirect, incidental or consequential damages, or any injury, arising from use of the app or taking part in a challenge. Nothing in these terms limits liability that can't be limited by law, or your rights as a consumer.
