Splitmaxx Terms of Service

Last updated: October 28, 2026 Effective date: September 25, 2026

These Terms of Service ("Terms") are a legal agreement between you and Max Thienel, the individual developer of Splitmaxx ("we," "us," "the developer"), governing your use of the Splitmaxx iOS app and splitmaxx.com (together, "Splitmaxx" or "the Service"). By creating an account or using Splitmaxx, you agree to these Terms.

1. Eligibility

You must be at least 13 years old (or at least 16 years old if you are located in the European Economic Area or United Kingdom, or the applicable minimum age of digital consent in your country if different) to use Splitmaxx. By using the Service, you represent that you meet this requirement.

2. The Service

Splitmaxx is a personal workout tracker: you log exercises, sets, reps, and weight, track streaks, and can optionally join callouts (friend competitions on a lift).

Splitmaxx is free to use for logging and tracking your workouts. Some features (currently group callouts beyond your first, 2-week and 1-month callouts, and the health widgets) require an optional paid subscription, described in Section 13. 1-week 1v1 callouts, one group callout and joining callouts you're invited to are free. Splitmaxx is still evolving, which means:

  • Features may be added, changed, or removed over time. If we make a material change to a Premium feature, we will tell you in the app.
  • The Service may experience bugs, downtime, or data loss more often than a long-established product.

3. Your Account

You're responsible for maintaining the confidentiality of your account credentials and for all activity under your account. Notify us promptly at support@splitmaxx.com if you suspect unauthorized access to your account.

You may sign up using email/password, Sign in with Apple, or Google Sign-In. You're responsible for keeping the underlying Apple ID or Google account secure if you use those options.

4. Acceptable Use

You agree not to:

  • Use Splitmaxx for any unlawful purpose or in violation of these Terms;
  • Harass, abuse, or impersonate other users, including within callouts;
  • Attempt to gain unauthorized access to the Service, other users' accounts, or our systems;
  • Interfere with or disrupt the Service or its infrastructure;
  • Submit false workout data with the intent to manipulate callout standings in a way that misleads other users;
  • Reverse-engineer, decompile, or attempt to extract the source code of the app, except as permitted by applicable law.

There is no tolerance for objectionable content or abusive users. Display names, callout names and anything else you submit must not be offensive, hateful, sexually explicit, threatening, or harassing. You can report a person or a callout, and block a person, from within the callout. We review reports within 24 hours and may remove the content and suspend or terminate the account responsible.

We may suspend or terminate accounts that violate these rules.

5. Your Content

You retain ownership of the workout data, display name, and any other content you submit to Splitmaxx ("Your Content"). By submitting Your Content, you grant us a limited, non-exclusive license to store, process, and display it as necessary to operate the Service — for example, showing your display name and standings to other members of a callout you've joined, or backing up your workout data to the cloud if you enable that feature.

6. No Medical Advice

Splitmaxx is a workout-logging tool. Nothing in the app constitutes medical, health, or fitness advice. Splitmaxx does not diagnose, treat, or provide guidance on any medical condition, and workout data, streaks, or callout standings should not be interpreted as medical or professional fitness guidance. Consult a qualified physician or fitness professional before beginning any exercise program, especially if you have a pre-existing health condition. You use Splitmaxx, and any exercise program you track with it, entirely at your own risk.

7. Third-Party Services

Splitmaxx uses third-party services to operate (including Supabase, PostHog, Sentry, Resend, Apple, and Google, as described in our Privacy Policy). Your use of Sign in with Apple or Google Sign-In is also subject to those companies' own terms.

8. Disclaimers

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE, OR THAT YOUR DATA WILL NEVER BE LOST.

9. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE DEVELOPER WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF DATA, ARISING FROM YOUR USE OF THE SERVICE. TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE DEVELOPER'S TOTAL LIABILITY TO YOU FOR ANY CLAIM ARISING FROM THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID FOR SPLITMAXX PREMIUM IN THE TWELVE MONTHS BEFORE THE CLAIM AND (B) FIFTY U.S. DOLLARS ($50).

Some jurisdictions don't allow the exclusion or limitation of certain damages, so some of the above limitations may not apply to you.

10. Termination

You may stop using Splitmaxx and delete your account at any time from within the app. We may suspend or terminate your access to the Service at any time, with or without cause, including for violation of these Terms. Sections 5, 6, 8, 9, 11, and 12 survive termination. Termination does not cancel an Apple subscription; see Section 13.

11. Governing Law

These Terms are governed by the laws of the State of New York, without regard to its conflict-of-laws principles. Any dispute arising from these Terms or the Service will be resolved in the state or federal courts located in the State of New York, and you consent to personal jurisdiction in those courts. (These Terms do not require arbitration.)

If you are a consumer residing in the EU, UK, or another jurisdiction that grants you the benefit of mandatory local consumer-protection laws, this section does not deprive you of the protection of those mandatory provisions.

12. Changes to These Terms

We may update these Terms from time to time as Splitmaxx evolves. If we make material changes, we'll update the "Last updated" date and, where appropriate, provide additional notice (such as an in-app notice). Continued use of Splitmaxx after changes take effect means you accept the updated Terms.

13. Splitmaxx Premium subscriptions

What it is. Logging workouts, history, stats and streaks are free. Splitmaxx Premium is an optional subscription that unlocks the features marked Premium in the app: currently group callouts beyond your first, 2-week and 1-month callouts, and the Recovery, Sleep and Heart Rate Zones widgets. 1-week 1v1 callouts, one group callout and joining callouts you're invited to are free.

Plans and price. Premium is offered as a monthly or an annual auto-renewing subscription. The price and billing period are shown in the app, in your local currency, before you subscribe, and are confirmed by Apple when you purchase. Taxes may apply.

Payment. Payment is charged to your Apple ID account at confirmation of purchase. Purchases are processed entirely by Apple; we never see or store your payment details.

Auto-renewal. Your subscription renews automatically for the same period, at the then-current price, unless you cancel at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours before the end of the current period.

Managing and cancelling. You can manage or cancel your subscription at any time in Settings > your name > Subscriptions on your iPhone, or from Manage Subscription in the app. Cancelling stops future renewals; you keep Premium until the end of the period you've paid for. Deleting the app or your Splitmaxx account does not cancel your subscription. You must cancel it with Apple.

Free trials and introductory offers. If we offer one, any unused portion of a free trial is forfeited when you purchase a subscription, and eligibility is determined by Apple.

Refunds. Refunds for App Store purchases are handled by Apple (reportaproblem.apple.com); we can't issue them.

Price changes. If the price changes, Apple will notify you and, where required, ask for your consent. If you don't agree, you can cancel before the change takes effect.

If your subscription ends. We keep all of your data, including your workout history and callout history. Premium features become unavailable until you subscribe again, and access returns as soon as you do. Premium callouts you belong to keep running for their other members; while you aren't subscribed you can't view or add to them, but you can always leave a callout.

Beta accounts. Accounts created during the public beta may keep Premium features at no charge. We may change that with notice in the app.

Apple. Your purchase is also subject to Apple's Licensed Application End User License Agreement (the standard EULA) and the App Store's terms. In a conflict about a purchase, Apple's terms govern the purchase itself.
