YOUR INFORMATION, WITH CARE

Privacy & data.

This guide explains the privacy controls implemented in Headlull. Updated 18 October 2026.

This is a product guide, not the final app privacy policy. The operator’s complete policy, including deployed service providers and retention details, must be confirmed before the public app launch.

What can I record?

The app lets you record headaches, symptoms, possible triggers, medication use, and daily check-ins. Optional features may use additional information, such as a chosen weather area or health data you permit the app to read.

Where do my entries go?

Headlull stores entries in an encrypted database on your device. Account sync sends records to the Headlull service when connected. Offline storage does not mean your account records remain only on your phone.

Which controls are available?

• Review health-data consent in the app.
• Enable an optional app lock using your device’s authentication.
• Choose whether to share crash reports; the app defaults this setting to off.
• Manage optional health, location, and notification features.
• Request a data export or account deletion from Me → Privacy & data.

What does this website collect?

This website has no account forms, advertising scripts, or analytics scripts added by Headlull. Its hosting and network services process requests to deliver the pages. Email links open your own mail app; sending a message shares the information you include with Headlull support.

How can I ask a question?

Contact support@headlull.com. Do not send passwords or detailed health records in an initial email. For deletion instructions, see Delete your Headlull account.
