RainRoute

Your data, explained.

Privacy policy · Updated November 5, 2026

The short version

What we collect

Kept on your phone and your iCloud

The app keeps a log of the walks you take with navigation, for your stats: how far you walked, your time under sheds and which ones, and the neighborhoods where each walk started and ended. It stays on your phone, with a backup in your own iCloud on iPhone, and is never sent to RainRoute. For rain stats, the app asks our server for New York City's hourly weather by month, with no location. The Sheds stat page shows a map picture of a shed from Mapbox, our map provider. To delete your walk history from your phone and iCloud, choose Delete my data in Privacy, or Delete walk history at the bottom of Your stats.

Who helps us run RainRoute

A few service providers handle data for us, only to run RainRoute: hosting, the database, maps and search, error reports, analytics, and optional tips. Each one is listed below with its own privacy policy.

How long we keep it

Your choices

Tips and Supporter purchases

On the website, optional tips go through Ko-fi and its payment providers under their own policies. In the iPhone app, Supporter purchases go through the App Store under Apple's policies. We never see your card number or store account. The app only asks the store which purchases you own, and that stays on your phone.

Questions

Email hello@rainroute.nyc with any privacy question or request. If this policy changes, the date at the top will change too.
