Privacy policy
Cedar is designed to keep your allergy log on your iPhone and collect as little information as possible.
Information stored on your device
Cedar stores the information you enter—such as your ZIP code, symptom preferences, daily symptom scores, medication-taken indicators, reminder settings, and check-in history—locally on your device. Cedar also caches modeled environmental data and analysis results locally. Cedar does not require an account and does not provide cloud sync.
Environmental-data requests
To retrieve modeled environmental information, Cedar sends your five-digit US ZIP code and request parameters to Cedar's environmental-data service. The service uses WeatherAPI.com to retrieve pollen information and Cloudflare for hosting, security, and limited caching.
The Cedar service is designed not to write ZIP codes or coordinates to application logs. Cache identifiers are hashed. Cloudflare and WeatherAPI.com may process network information, including IP addresses and request metadata, under their own policies. See Cloudflare's privacy policy and WeatherAPI.com's privacy policy.
Notifications and sharing
If you allow notifications, Cedar schedules a daily reminder through iOS. You can deny or later disable notification access in iOS Settings. If you choose to share a clinician summary, Cedar creates the summary on your device and opens the iOS share sheet. Cedar does not control or receive the destination you select.
Analytics, advertising, and sale of data
Cedar does not include third-party advertising, cross-app tracking, or behavioral analytics, and does not sell your personal or health information. Cedar does not send your ZIP code, symptom log, medications, reports, or personal pattern results to RevenueCat.
Subscriptions
If you purchase Cedar Premium, Apple processes the payment and RevenueCat helps Cedar determine whether the subscription entitlement is active. Apple and RevenueCat may process subscription product, purchase, renewal, refund, device, network, and anonymous app-user identifier information under their own policies. Cedar does not create an account or provide RevenueCat with your name, email address, ZIP code, health log, or advertising identifier. See Apple's privacy policy and RevenueCat's privacy policy.
Retention and deletion
Your Cedar log remains on your device until you use Delete all local data in Cedar or remove the app. Deleting local data also cancels Cedar's scheduled reminder. Environmental responses may be cached for a limited period to improve reliability and reduce provider requests.
Children
Cedar may be used by teens or by a parent or guardian managing a child's allergy log. Cedar does not require an account, include advertising or social features, or knowingly collect a child's information on a Cedar server. A parent or guardian should supervise use by a child.
Medical information
Cedar is a self-tracking tool, not a medical device or medical service. It does not diagnose allergies or provide treatment advice. Do not use Cedar for emergencies.
Changes to this policy
Material changes will be posted on this page with a new effective date. The policy applicable to a release will remain publicly accessible.
