Sinus Shield is a personalized allergic rhinitis management tool that provides medication protocol recommendations based on environmental data (pollen levels, weather conditions, and air quality). The service is operated by EasyMuse.
Sinus Shield does not provide medical advice. The tier-based medication protocols are informational tools to help you follow a plan agreed upon with your healthcare provider. Always consult your doctor or pharmacist before starting, stopping, or changing any medication.
The environmental data (pollen counts, air quality indices) comes from third-party APIs and may not be perfectly accurate for your exact location. Use this information as a general guide, not as a clinical measurement.
You create an account using your email address via a magic link (passwordless authentication). You are responsible for maintaining access to your email account. We do not store passwords.
By using the service, you provide:
See our Privacy Policy for details on how we handle your data.
You agree to use the service for personal allergy management only. You may not use automated tools to access the service, attempt to access other users' data, or interfere with the service's operation.
We aim to provide reliable service but cannot guarantee 100% uptime. The service depends on third-party APIs (Google Pollen API, OpenWeatherMap, Google Air Quality API) which may experience outages. When external data is unavailable, the system uses conservative fallback values.
By enabling email notifications, you consent to receive daily morning and evening emails at your chosen times. You can disable notifications at any time in Settings. Emails are sent via Resend from sinus-shield@easymuse.app.
You can delete your account at any time from Settings. This permanently removes all your data including your profile, medication protocols, daily logs, and sensitivity learning history. This action cannot be undone.
Sinus Shield is provided "as is" without warranty of any kind. We are not liable for any health outcomes resulting from following or not following the medication protocols displayed by the service. The service is a reminder tool, not a medical device.
We may update these terms from time to time. Continued use of the service after changes constitutes acceptance of the updated terms.
