Phase

Your information, clearly explained

Privacy Policy

Effective 11 August 2026

Phase handles deeply personal information. This policy explains what we collect, why we use it, and the choices available to you.

1. Scope

This policy applies to the Phase iOS application and this website. "Phase", "we", and "us" refer to the operator of Phase in Aotearoa New Zealand.

Phase provides cycle-awareness and support-planning tools. It is not a medical device and does not provide medical advice, diagnosis, or treatment.

2. Information we collect

Information you provide

  • Account information: email address, Sign in with Apple identifier, and account role.
  • Cycle and wellbeing information: birth year, cycle timing, period dates, symptoms, impact, daily check-ins, relief goals, and related onboarding answers.
  • Support information: support preferences, notes you choose to write, private share codes, and the categories you consent to share.
  • Settings: notification preferences, analytics preference, and other app configuration.

Information generated when you use Phase

  • Subscription information: product-access and transaction status. Apple processes payment details; Phase does not receive your full card information.
  • Product analytics: limited events such as opening the app, completing onboarding, or viewing the paywall. These events are deliberately restricted and do not include cycle dates, symptoms, Health data, email addresses, or free-text notes.
  • Diagnostics: crash reports, operation names, timing, device/app information, and random correlation identifiers used to diagnose failures. Screenshots, view hierarchies, and default personally identifying fields are disabled.

3. How we use information

We use information to:

  • create and secure your account;
  • calculate and display your personalised cycle window and plan;
  • save your check-ins and preferences across sessions;
  • provide consent-based sharing to an authenticated support person;
  • process and restore subscriptions;
  • deliver local reminders you request;
  • understand broad product usage and improve reliability; and
  • prevent misuse, protect users, and comply with legal obligations.

We do not sell personal information. We do not use Health, cycle, symptom, or support-note information for advertising or ad targeting.

4. Service providers and disclosures

We use carefully selected providers to operate Phase:

  • Supabase for authentication, database hosting, and secure backend functions.
  • PostHog for restricted product analytics when analytics collection is enabled.
  • Sentry for privacy-limited crash reporting and performance diagnostics.
  • Superwall and Apple for paywall, subscription, purchase, and entitlement services.
  • Vercel for hosting this public website.

These providers process information on our behalf under their own security and privacy commitments. Information may be processed outside New Zealand. We may also disclose information if required by law, to protect safety and rights, or in connection with a business reorganisation subject to appropriate safeguards.

Support-person sharing is user-directed: a supporter must authenticate and redeem a private code, and only sees the categories the personal account holder enables. Access can be changed or revoked.

5. Apple Health

Apple Health access is optional and requires your explicit permission. If enabled, Phase reads relevant menstrual cycle history and may write period days you log so your records remain consistent.

Phase uses permitted Health information only to provide health and cycle features. It is not sent to PostHog, Sentry, Superwall, or advertising services. Cycle information derived from your import may be saved to your Phase account so the app can provide its core features across sessions.

You can review or revoke Health permissions at any time in the iOS Health app or Settings. Revoking access stops future Health access but does not automatically delete information already saved in your Phase account.

6. Your choices and rights

  • Analytics: turn product analytics collection on or off in Phase Settings.
  • Notifications: change notification preferences in Phase and iOS Settings.
  • Health: control Health permissions through Apple’s settings.
  • Sharing: choose shared categories and revoke supporter access.
  • Account deletion: delete your account from Phase Settings. This removes your Phase account and associated app records. Subscription cancellation is managed separately through Apple.

Depending on where you live, you may also have rights to access, correct, delete, or restrict use of your personal information. Contact us to make a request. We may need to verify your identity before responding.

7. Retention, security, and children

We retain account information while your account is active and as needed to provide Phase. When you delete your account, associated active account records are deleted; limited records may remain temporarily in protected backups, security logs, or where retention is legally required.

We use access controls, encrypted network connections, authenticated sharing, and database row-level security to protect information. No system can guarantee absolute security.

Phase is not directed to children under 13. If you believe a child has provided personal information without appropriate authorisation, contact us.

8. Changes to this policy

We may update this policy as Phase develops or legal requirements change. We will publish the updated version here and change the effective date. We will provide additional notice when a material change warrants it.
