Terms of Service
Version 1.0 · Effective June 3, 2026
These Terms are a binding agreement between you and Max Output LLC ("Max Output," "we," "us") governing your use of the Idunia mobile app.
1. Eligibility
You must be 18 or older and located in the United States to use Idunia. By using the app you confirm both. The app is offered only in the US. (Age is confirmed by a neutral date-of-birth entry, not a pre-checked box.)
2. What Idunia is — and is not
Idunia is a nutrition and training tracking tool for general wellness and performance. It is not a medical device, and nothing in it is medical advice, diagnosis, or treatment. Energy-availability / RED-S indicators, micronutrient indicators, and cycle information are informational only. Always consult a qualified clinician or dietitian for medical decisions. The app does not detect, diagnose, or rule out pregnancy or any medical condition.
3. Your account
You are responsible for your login credentials and for the accuracy of what you enter. You may delete your account anytime in Settings.
4. Acceptable use
Don't misuse the app: no unlawful use, no attempts to breach security, no reverse engineering except as permitted by law, no use on behalf of anyone under 18.
5. Your data
Your data is governed by our Privacy Policy and Consumer Health Data Privacy Policy. Cycle data is stored only on your device; uninstalling the app removes that on-device data but does not delete your account or server-side data.
6. Subscriptions and payment
Idunia may offer optional auto-renewing subscriptions.
- Billing. Subscriptions are sold and billed by Apple (App Store) or Google (Google Play) through your Apple ID or Google Play account. We do not process card payments directly.
- Auto-renewal. Your subscription automatically renews at the price and billing interval shown at the time of purchase, and your account is charged at each renewal, until you cancel. On Apple, the subscription renews unless you cancel at least 24 hours before the end of the current period.
- Cancellation. You can cancel anytime in your App Store or Google Play account settings. Cancellation takes effect at the end of the current paid period, and you keep access until then. Canceling stops future renewals; it does not by itself refund the current period.
- Refunds. Refund requests for App Store purchases are handled solely by Apple under its policies; refund requests for Google Play purchases are handled by Google and/or us under Google Play's policies.
- Price, billing interval, free-trial terms (if any), and whether a subscription is required are shown clearly at the point of purchase. Apple's standard Licensed Application End User License Agreement also applies to your use of the iOS app.
7. Disclaimers
The app is provided "as is." We do not warrant that calculations are error-free or suitable for your individual circumstances. Use your judgment and professional guidance.
8. Limitation of liability
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL MAX OUTPUT LLC, ITS AFFILIATES, OR THEIR OFFICERS, EMPLOYEES, OR AGENTS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, DATA, GOODWILL, OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR RELATING TO THE APP OR THESE TERMS, WHETHER BASED ON WARRANTY, CONTRACT, TORT (INCLUDING NEGLIGENCE), STATUTE, OR ANY OTHER LEGAL THEORY, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. OUR TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THESE TERMS OR THE APP WILL NOT EXCEED THE GREATER OF (A) THE TOTAL AMOUNTS YOU PAID TO US FOR THE APP IN THE TWELVE (12) MONTHS IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) ONE HUNDRED U.S. DOLLARS ($100). SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR LIMITATION OF CERTAIN DAMAGES, SO SOME OR ALL OF THE ABOVE EXCLUSIONS AND LIMITATIONS MAY NOT APPLY TO YOU, AND NOTHING IN THESE TERMS LIMITS LIABILITY THAT CANNOT BE EXCLUDED OR LIMITED UNDER APPLICABLE LAW.
9. Governing law and dispute resolution
Governing law. These Terms and any dispute arising out of or relating to them or the app are governed by the laws of the State of North Carolina, without regard to its conflict-of-laws principles.
Informal resolution first. Before starting an arbitration or any other proceeding, you and Max Output agree to try to resolve the dispute informally for at least 60 days after written notice (to founders@maxoutput.ai, or to your account email from us).
Binding individual arbitration. If we can't resolve it informally, you and Max Output agree that any dispute will be resolved by binding individual arbitration administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules, and, where applicable, its Mass Arbitration Supplementary Rules. Judgment on the award may be entered in any court with jurisdiction.
YOU AND MAX OUTPUT AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN AN INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY CLASS, COLLECTIVE, OR REPRESENTATIVE PROCEEDING. YOU AND MAX OUTPUT WAIVE ANY RIGHT TO A JURY TRIAL.
Small-claims carve-out. Either party may bring an individual claim in small-claims court instead of arbitration if it qualifies.
30-day opt-out. You may opt out of this arbitration agreement by emailing founders@maxoutput.ai within 30 days of first accepting these Terms, stating your name and that you opt out of arbitration. If you opt out, the court-venue clause below governs.
Court venue (for disputes not subject to arbitration). Any dispute not subject to arbitration shall be brought exclusively in the state or federal courts located in Mecklenburg County, North Carolina, and each party consents to the personal jurisdiction and venue of those courts.
10. Changes
We may update these Terms; material changes will be notified in-app. Continued use after a change means you accept the updated Terms. This does not override the separate, opt-in consent required under privacy law for new uses of your health data.
