Terms of Service

Last updated: 26 August 2026

German version: keizoku.space/agb.html.

1. Provider and scope

These terms govern the use of the Keizoku website and, once released, the Keizoku iOS app. The provider is Kevin Bright, Keizoku (sole proprietorship), Motterstr. 39, 90451 Nürnberg, Germany (kdbright92@gmail.com).

2. What Keizoku is — and is not

Keizoku helps you plan workouts around your calendar, reschedules them when conflicts appear and recognizes completed workouts. It does not create training plans and does not provide medical, health or nutrition advice. Whether and how you train remains your own decision and responsibility. If you have health concerns, consult a qualified professional before exercising.

3. Accounts and acceptable use

You agree to use Keizoku only as intended: for planning your own workouts. You may not attempt to disrupt the service, reverse engineer it beyond what the law permits, or use it for unlawful purposes.

4. Subscriptions and trial

• The free tier includes weekly goals, manual planning and reminders.
• Keizoku Pro is a subscription: €29.99 per year or €3.99 per month. The prices shown in the App Store at the time of purchase are decisive.
• New accounts receive a one-time 14-day trial with full Pro access. No payment details are required for the trial; it ends automatically and does not convert into a paid subscription by itself.
• Purchases, billing, renewal, cancellation and refunds are handled by Apple through your Apple account and Apple’s Media Services Terms. You can cancel any time in your App Store subscription settings.

5. Intellectual property

The Keizoku name, logo, design and content of this website and the app are protected. You may not reuse them without permission, except where the law allows it.

6. Availability

The app is provided with reasonable care, but we cannot guarantee uninterrupted availability. Features that depend on third-party services (calendar providers, Apple Health, the App Store) can be limited when those services change or are unavailable.

7. Liability

We are liable without limitation for intent, gross negligence, injury to life, body or health, and under mandatory statutory rules such as product liability law. For slight negligence we are liable only for the breach of essential contractual obligations (cardinal duties) and limited to the foreseeable damage typical for this kind of contract. Any further liability is excluded.

8. Governing law

German law applies. If you are a consumer, the mandatory consumer protection rules of the country of your habitual residence remain unaffected.

9. Dispute resolution

We are neither willing nor obliged to participate in dispute resolution proceedings before a consumer arbitration board (§ 36 VSBG).

10. Changes to these terms

We may update these terms when the product changes. The current version is always available at this address; material changes to a running subscription will be announced in the app.
