Privacy Policy | My Asthma Life

Local-first tracking

My Asthma Life is designed around local-first tracking. Health logs, journal notes, medication records, measurements, settings, reminder preferences, environment snapshots, exports, and related app data may be stored on your device or in your browser first.

Account and sync

If you sign in or enable cloud-backed sync, supported records may be stored with My Asthma Life's backend provider so they can be available across supported devices. Not every local table syncs, and some cache/provenance data stays local.

Subscriptions

Public web Premium subscription checkout, payment details, invoices, and billing portal access are processed through Stripe. Billing records are separate from asthma tracking records.

No selling personal data

My Asthma Life does not sell personal data. Information is used to operate the app, provide requested features, support accounts, process subscriptions, and respond to support requests.

What may stay local

Daily logs, journal notes, medication setup and dose logs, rescue use, asthma event history, monthly check-ins, peak flow, pulse ox, app settings, and local insight summaries may be stored on your device/browser.
Environment snapshots, imported QA/restore data, local trigger-pattern summaries, sync queue state, and downloaded export files may also remain local unless a supported sync or cloud feature uses them.
Exported CSV or report files are controlled by you after download or sharing. They can contain sensitive health information, so store and share them carefully.

What may leave your device

Account and sync: when you sign in or use cloud-backed sync, supported records may be sent to Supabase for authentication, database storage, restore, sync, reminder infrastructure, and account support.
Authentication: email sign-in uses Supabase auth. Google Sign-In and Apple Sign-In may be available when configured for the current build/platform, and those providers handle their own sign-in flow.
Reminders: web/PWA background reminders may store reminder rules and a browser push subscription in Supabase. Browser/device notification permission and push delivery are handled by the browser/platform.
Environment: ZIP/postal code or derived coordinates may be used to request AQI/weather from Open-Meteo. Trusted shared AQI/weather reference rows may be read from Supabase and cached locally. Premium pollen details, when available, are requested through a Supabase function that calls Google Pollen.
Billing: web Premium checkout and billing portal flows go through Stripe. Native Android purchases are inactive for the current PWA/web launch. Billing providers process payment details separately from asthma tracking data.
Ads: mobile builds may include banner ads through Google Mobile Ads / AdMob where that integration is active. Premium and Care Access hide the current mobile banner ad surface while access is active.
Support: if you email support, your email address and the details you choose to include are processed so we can respond. Please do not send passwords, card numbers, or unnecessary health details.

Service providers and processors

Supabase for authentication, database, backend functions, sync, reminder rules, push subscription records, entitlement state, and support operations.
Stripe for public web subscription checkout, billing portal, payment processing, invoices, and billing records.
Google for Google Sign-In where enabled, Google Pollen provider data for Premium environmental details where available, and Google Mobile Ads / AdMob on mobile where active.
Apple for Apple Sign-In where enabled and configured on the current platform.
Open-Meteo for AQI/weather and location-based environment lookups.

Deletion and retention

Deleting local device data removes data from that device/browser, but it may not delete cloud/account data, billing records, or copies on another device.
Deleting cloud/account data is handled through the app where supported or by contacting support. It is separate from canceling billing.
The in-app account-data deletion control clears local account/sync data on the initiating device, cancels local notifications, attempts supported cloud cleanup for the current user, records a deletion marker to prevent stale synced data from coming back, and signs out. It does not delete the Supabase auth user or Stripe billing records.
Canceling a Stripe subscription does not delete app data. Deleting app data does not cancel Stripe billing.
Some limited records may be retained or anonymized where needed for billing, fraud prevention, security, legal, tax, audit, dispute, or operational purposes.
We aim to review and process account/data deletion requests within 30 days. Third-party processors may keep records under their own policies.

Your choices

You can use core local tracking without public checkout. If you use account-based sync, you can review account/data controls in the app or request account or cloud-data deletion through support. Billing cancellation is handled separately through Manage Billing in the app for Stripe-backed Premium subscriptions. See Account/Data Deletion.
