HealthTac Privacy Policy

Effective September 14, 2026

The short version: HealthTac has no servers, no accounts, no analytics, no ads, and no third-party services. The app contains no networking code at all. Your health data is read from Apple Health, processed entirely on your device, and never transmitted anywhere — except when you personally choose to share it.

What data HealthTac uses

With your permission, HealthTac reads the following from Apple Health (HealthKit) on your iPhone and Apple Watch:

• Heart data — heart rate, resting heart rate, heart rate variability
• Respiratory data — blood oxygen, respiratory rate, breathing disturbances
• Sleep data — sleep stages, duration, and related measurements
• Activity data — steps, exercise minutes, active energy, and related measurements
• Wrist temperature
• Clinical health records (lab results, conditions, medications) — only if you connect them, used to tailor alert thresholds to your diagnosed conditions
• Motion data — live step counts between Apple Health syncs

Where your data lives

All processing happens on your device. HealthTac keeps a local performance cache of daily summaries so the app opens quickly; this cache never leaves your device. Apple Health remains the system of record for your health data at all times. HealthTac's developer cannot see, access, or receive your data — there is nothing for it to be sent to.

What HealthTac writes to Apple Health

Only entries you create: naps you record on your watch, and sleep entries you add manually. Nothing is written without your action.

When data leaves your device

Only when you choose:

• Sharing a report. If you export or share a PDF report (for example, with your doctor), it goes only where you send it.
• Emergency texts. If you enable this optional feature and configure a contact, a critical alert can send that person a text message naming the alert after a cancellable countdown. This feature is off by default and requires your explicit setup.

Notifications

All notifications are generated locally on your device. HealthTac uses no push-notification servers.

Analytics and tracking

None. HealthTac contains no analytics, no advertising, no tracking, and no third-party software components.

Data retention and deletion

Deleting the app deletes everything HealthTac stored on your device. Your health data in Apple Health is unaffected and remains fully under your control in the Health app, where you can also revoke HealthTac's permissions at any time (Settings → Privacy & Security → Health).

Children

HealthTac is not directed at children under 13 and does not knowingly collect information from them.

Not a medical device

HealthTac is a wellness app. It is not a medical device and does not diagnose, treat, or prevent any condition. If you feel unwell, contact your doctor or emergency services.

Changes to this policy

If this policy changes, the updated version will be posted at this address with a new effective date.
