Kaizen Terms of Service

Last updated: 2026-05-19

These terms govern your use of the Kaizen iOS app. They are short on purpose. Read them once before you sign up.

1. What Kaizen is

Kaizen is an iOS app that calculates 1%-per-day improvement targets for habits you choose, and records your daily progress.

It is not a medical device, not a therapeutic intervention, and is not a substitute for advice from a qualified professional. The anchor research summaries embedded in each habit template are paraphrased from published sources and are informational, not prescriptive.

2. Your account

You can use Kaizen by signing in with Apple, Google, or email + password. By creating an account, you confirm that:

• You are at least 13 years old (or 16 in jurisdictions that require it).
• The email address or auth identifier you sign up with is one you control.
• You will not share your account with another person.

3. License

We grant you a limited, non-exclusive, non-transferable, revocable license to install and use the app on Apple devices you own or control, for personal use, subject to these terms and to Apple’s App Store Terms of Service.

4. Acceptable use

You agree not to:

• Reverse engineer, decompile, or disassemble the app outside the limits permitted by Apple’s iOS terms and applicable law.
• Use Kaizen to harass, threaten, or impersonate other people.
• Attempt to access accounts, data, or systems you are not authorised to access.
• Scrape or otherwise extract data from our servers via automated means.
• Use Kaizen for any unlawful purpose.
