Privacy Policy

Effective: May 12, 2026

Cadence respects your privacy. This policy describes what data Cadence collects, how it's used, and your rights.

What Cadence collects

• Account email — required to sign you in and recover access.
• Menstrual cycle entries — the start and end dates of periods you log. Stored encrypted on our servers.
• Optional partner connection — if you share with a partner via an invite code, the relationship between your accounts is stored so the partner can view your countdown.
• Optional notification preferences — your push token and lead-day reminder choices.
• Diagnostic crash data — anonymized error reports via Apple's TestFlight / App Store crash reporting.

How Cadence uses your data

• To show your cycle history and predictions in the app.
• To deliver opt-in reminders before predicted period start dates.
• To allow a partner you explicitly invited to view your countdown.

Third parties

• Supabase — authenticated database and email delivery. Cycle dates are encrypted at rest.
• Apple HealthKit — only if you opt in. Cadence reads and writes the Menstrual Cycle category. Data stays on your device.
• Google AdMob — serves non-personalized advertisements only. Cadence does not request tracking permission. No personally identifiable data is shared.

Data you control

• Export your cycle data as a CSV at any time (Settings → Export my data).
• Delete your account permanently (Settings → Delete account). Deletion removes all personally identifiable data from our servers.

Your rights

You may request a copy of all data we store about you at any time, or request deletion of your account and all associated data, by emailing trevor.frese@gmail.com.

Children

Cadence is not directed at children under 13 and does not knowingly collect data from them.
