The apps are deliberately simple. Most questions are answered here.
Yes. The apps are built to work fully offline — that's the whole point. A connection is only ever used (where noted) for an optional one-time data refresh, and the app works without it.
No. There are no accounts, logins, or sign-ups in any of the apps.
The apps are free. They ship with no ads and nothing to buy.
Nothing. See the privacy policy — there are no servers, no analytics, and no tracking.
Some apps bundle a snapshot of data (transit, venue, reference info). Updates ship as app updates — make sure you're on the latest version from the App Store. If something is wrong, email us with the specifics and we'll fix it in the next update.
Only apps that show nearby things or compute local sun times ask, and only to use it on your device in that moment. You can decline and still use the app. Location is never stored or sent anywhere.
Please send it — these apps improve from traveler feedback. Email the app name and the detail.
