Privacy Policy

My Hayfever · Last updated 23 June 2026

This Privacy Policy explains what information the My Hayfever app ("the App", "we", "us") collects, how we use it, and your choices. By using the App you agree to this policy.

Who we are

The App is operated by My Hayfever. You can contact us at trivialsixseven@gmail.com.

Information we collect

We only collect what the App needs to work:

• Account information — when you sign in to post, we receive an email address via Sign in with Apple or Google. You can use the App's tracking features without signing in.
• Health-related information you enter — symptom ratings, medications and reminders, food logs, and notes, which you provide to track your own hayfever.
• Location — if you allow it, an approximate (town-level) location to show your local pollen forecast, or an area you set manually. A location may be attached to a card you choose to share.
• Content you post — if you share a card to the public feed: your symptom card, an optional note, an optional display name, an optional photo, and reactions.
• Notifications — a device token if notifications are enabled, used to deliver reminders.

We do not collect data for advertising, and we do not use third-party tracking or advertising SDKs.

How we use your information

To provide the App's features (forecast, tracking, reminders, the community feed); to operate and secure the service; and to respond to support requests and content reports. We do not sell your personal information, and we do not share your health information with third parties for marketing.

The community feed

Cards you choose to share are visible to other users for a limited time (about 24 hours). You can post anonymously. We operate a zero-tolerance policy for objectionable content and abusive behaviour: you can report content and block users in the App, and we act on reports (typically within 24 hours), including removing content and offending users.

Service providers

We use Supabase (database, authentication, and file storage) to run the App, and Apple and Google for sign-in. Your data is stored on their infrastructure on our behalf.

Data retention and deletion

You can delete your account at any time from within the App (Profile → Delete account), which permanently removes your account and associated data. Shared feed cards expire from the public feed automatically.

Children

The App is not directed to children under 13 (or the equivalent minimum age in your country) and we do not knowingly collect their data.

Your rights

Depending on where you live, you may have rights to access, correct, or delete your personal data. The quickest way to delete your data is the in-app account deletion. For other requests, contact trivialsixseven@gmail.com.

Changes

We may update this policy; we will update the "Last updated" date above.
