Privacy Policy
Sniffle · Last updated October 1, 2026
Sniffle shows pollen and allergy information for places you choose. We collect as little as possible, and we never sell your data.
What leaves your phone
- Approximate location. To look up pollen, the app sends a location rounded to about 1 km (0.6 miles) to our server. The server rounds it again to an area about 20 km (12 miles) across and asks our pollen provider about that area's center, not your location. We don't store your location.
- A random device ID. Used only to stop any one device from overloading the service. It isn't linked to you, your Apple Account or your other apps.
- Weather. The app asks Apple Weather for rain at your location. Apple's handling of that is covered by Apple's Privacy Policy.
Our hosting provider (Cloudflare) may keep short-lived technical logs, such as request times and errors, for security and troubleshooting.
What stays with you
Your triggers, daily check-ins, saved places, alert settings and Insights are kept on your device. If you're signed in to iCloud, they're also kept in your own iCloud account, so they come back if you reinstall Sniffle or get a new iPhone. We never receive them. To delete your check-ins and Insights history from your iPhone and iCloud, open Insights in the app and tap Clear My History. Deleting the app removes the copy on your phone but not the one in iCloud.
Pollen data from Google
Pollen data comes from the Google Maps Platform Pollen API. Our server sends Google the center of the area being looked up, not your location or any information about you. Google's handling of data is covered by the Google Privacy Policy.
Purchases
Subscriptions are handled by Apple. We never see your payment details.
What we don't do
No accounts, no ads, no tracking across apps or websites, no selling or sharing of personal data.
Children
Sniffle isn't directed to children under 13, and we don't knowingly collect information from them.
Changes
If this policy changes, we'll update this page and the date above.
