The short version
What's My 20? uses your location on your iPhone, Apple Watch and in CarPlay to show and read out the nearest address. We have no servers and no accounts, and we never see your location. The free version shows Google ads, which collect some device and usage data to show and measure ads; buying the upgrade removes them.
What the app stores and where
| Data | Where it lives | Why |
|---|---|---|
| Your current location | Only in memory on your device while the app is open; never saved | To find the nearest address, hundred block and heading |
| Settings (voice, speech speed, display options) | On your device | To remember your choices |
| Highway mile marker files for the states you download | On your device | To show the mile marker and nearest exit on highways, without signal |
| Whether you bought the upgrade | Apple keeps the purchase record; the app keeps a copy on your device | To turn on speaking and remove ads |
What leaves your device
To turn your position into a street address, the app sends your coordinates to Apple's map service (the same one Apple Maps uses), under Apple's privacy policy. Nothing is sent to us. In the free version, Google's ad service receives information it needs to show ads: your device's IP address (from which it can estimate a rough region), device type and settings, an app-specific device identifier, and which ads you see and tap. The app does not give Google your GPS location or any address, and it does not ask to track you across other companies' apps and websites. After you buy the upgrade, no ads are loaded. If you download highway mile markers for a state in Settings, the file comes from this website (warriormadeproductions.com, hosted by GitHub Pages), which sees your device's IP address like any website does; the download never includes your location. Oklahoma's is built into the app.
Third-party services
- Apple Maps (address lookup) and App Store (the in-app purchase): Apple Privacy Policy.
- OpenStreetMap: highway exits and mile markers, built into the app or downloaded from this website. Nothing is sent to OpenStreetMap. Data © OpenStreetMap contributors, under the Open Database License.
- GitHub Pages hosts this website and the highway files: GitHub Privacy Statement.
- Google AdMob (ads in the free version), with Google's consent form where the law requires one: Google Privacy Policy and how Google uses information from apps that use its services.
Permissions the app may ask for
- Location (while using the app): to show and read out the nearest address and your heading.
Each permission is requested only when you use the feature that needs it, and you can change it any time in Settings → What's My 20?.
Deleting your data
We don't hold any of your data, so there's nothing for us to delete. Deleting the app removes your settings from your device. To reset Google's ad identifier for your device, delete the app; you can also manage ad personalization at myadcenter.google.com.
Children
What's My 20? is not directed at children under 13 and does not knowingly collect personal information from them.
Changes
If this policy changes, the new version is posted here with a new effective date. Material changes are also noted in the app's release notes.
