SunNav is a golf-cart GPS navigation app built for 55+ communities. This page explains what information SunNav collects, how it's used, and the choices you have. We've tried to write it in plain language rather than legal boilerplate. It covers SunNav for both iPhone and Android; where the two versions differ, we say so.
The short version: SunNav has no user accounts and no backend server of its own. Your location, favorites, and preferences stay on your device. On iPhone, crash reports are collected automatically to keep the app stable, and usage analytics are off by default and only run if you turn them on. The Android version includes neither. We never sell your data.
SunNav uses your device's GPS location to show your position on the map and provide turn-by-turn navigation, including while the app is in the background during active navigation (so voice guidance keeps working if you switch apps or lock your phone). On Android, a notification is shown the whole time navigation is running in the background, and background location use stops when you end navigation. Location data is processed on your device and sent to our mapping and routing providers (see "Third-Party Services" below) only as needed to calculate routes and display maps. We do not store your location history on any server we control.
If you choose to use the "navigate to a contact" feature, SunNav requests access to your Contacts to look up saved addresses. This data is read and used entirely on your device to help you pick a destination — it is never uploaded or transmitted anywhere. You can deny or revoke this access at any time in your device's Settings without affecting the rest of the app.
Saved favorites, your selected community, offline map downloads, and app settings are stored locally on your device. This information is not sent to us and is not accessible to us.
SunNav is a one-time paid download, processed entirely through your Apple ID via Apple's App Store, or through your Google account via Google Play. We do not see or store your payment details — Apple or Google handles billing directly, and we have no visibility into your purchase beyond what they report in aggregate sales data.
On iPhone, SunNav automatically sends crash and error reports using Sentry, so we can find and fix bugs. These reports include technical details like device model, OS version, app version, and the code path where an error occurred. We explicitly configure Sentry to never capture screenshots and to strip out any location data before it's sent. The Android version does not include Sentry and sends us no crash reports.
On iPhone, SunNav can optionally share anonymous, aggregated usage data (like which features are used) via PostHog, to help us understand what to improve. This is off by default. You can turn it on or off any time in Settings → Privacy → Analytics. When enabled, no personal information or precise location is ever included in these events. The Android version does not include PostHog and has no such setting.
The Mapbox maps software built into SunNav collects anonymized map usage data (telemetry), which can include location, to help Mapbox improve its maps. This goes to Mapbox, not to us, and is not linked to your name or any account.
If you use "Report an Issue" in Settings, or otherwise email us at support@sunnav.app, you're voluntarily sharing your email address and whatever you write, along with basic diagnostic info (app version, device model, OS version, selected community) to help us troubleshoot. We use this only to respond to you and improve the app.
SunNav relies on a small number of trusted third-party services to function. Each processes a limited slice of data for a specific purpose, governed by their own privacy policies:
| Service | Purpose | Data Involved |
|---|---|---|
| Mapbox | Maps, turn-by-turn routing | Location coordinates needed to render maps and calculate routes; anonymized map usage data |
| OpenStreetMap (Overpass API) | Road, crossing & parking data for your community | Map area (bounding box) — no personal identifiers |
| Sentry | Crash & error reporting (iPhone only) | Device/OS/app version, error details (no screenshots or location) |
| PostHog | Optional usage analytics (iPhone only) | Anonymous feature-usage events — only if you opt in |
| Cloudflare | Routing support emails | Forwards messages sent to support@sunnav.app to our inbox |
SunNav is designed for residents of 55+ communities and is not directed at children. We do not knowingly collect information from anyone under 13.
Since SunNav has no backend of its own, the vast majority of your data (location, favorites, preferences) simply lives on your device and is deleted when you delete the app. Diagnostic and optional analytics data held by our third-party providers is retained according to their own retention policies, generally on the order of months, and is not linked to your identity.
If this policy changes in a meaningful way, we'll update the "Last updated" date above. Continued use of SunNav after a change means you accept the updated policy.
