Privacy

Treated like therapy notes.

KAIZEN ("we", "us", "our") is a manifestation, affirmation, and journaling app for iOS and Android. We hold a lot of sensitive material per user — voice, story, blockers, journals — and this policy is how we promise to treat it. The shorter never-list lives at What we'll never do. This Privacy Policy is a binding statement of our practices. We may amend it; we'll email account holders before any change that materially affects how we collect or use data.

Applies to the KAIZEN app and getkaizen.app. Contact: [email protected].

Last updated: June 2026.

Our four principles

  1. Consent is explicit, granular, and revocable. Never one big "agree to everything."
  2. Delete means delete. Including at third-party providers (voice clones, LLM caches).
  3. Anonymity by default in social. You choose to deanonymise; never the other way around.
  4. We never replace a professional. KAIZEN is not therapy, medicine, or legal counsel.

What we collect

What we use it for

We do not sell data, do not train third-party models on your data, do not show advertising, and do not share your content with other users.

Who processes your data (subprocessors)

We use a small set of vetted service providers to run KAIZEN. Each only receives the data it needs to do its job, under contract, and none of them may sell your data or use it to train their own or third-party models on your content.

We keep an up-to-date list and will notify account holders before adding a subprocessor that materially changes how sensitive data is handled. In transit: TLS everywhere. At rest: encryption provided by each vendor; voice and journal audio additionally encrypted at the application layer with a per-user key.

Your voice (voice biometrics)

A voice recording can be biometric data. We treat it with extra care, and we only ever process it with your explicit, opt-in consent.

Anonymity in community

Sensitive content

KAIZEN routes sensitive content (self-harm, abuse, substance use, eating concerns) to in-app resource screens with jurisdiction-aware hotlines. We suppress AI generation that could harm rather than help. We do not alert humans on private-journal sensitive content — you wrote it for yourself.

Your rights

Retention

Account active: as long as you keep the account. Account deleted: full data wipe within 30 days, including at third-party providers. Crash diagnostics (with no user ID): retained 90 days. Aggregated, non-identifying product metrics: retained indefinitely.

Children

KAIZEN is built for people 16 and older. We collect month + year of birth once, for the age check; we don't display it in the app and it's deleted with your account. We do not knowingly accept users under 16.

International transfers

KAIZEN is operated from, and stores data in, the United States at launch. If you sign up from the EU, UK, or another region, you acknowledge that your data is processed in the US under appropriate safeguards; an EU GDPR data-processing addendum is available on request from [email protected].

Legal basis & how we share

We process your data to provide the service you asked for (performance of our agreement with you), on the basis of your explicit consent for voice and other optional features, and for our legitimate interest in keeping the product working and safe. We do not sell personal data and do not share your content for advertising. We may disclose data if required by law or to protect users, and we may transfer it as part of a merger or acquisition (you'll be notified).

This policy reflects how KAIZEN actually handles your data and is the binding statement of our practices. See also our Terms of Service, EULA, and FAQ.
