Privacy

No accounts, no analytics, no tracking. Your position never leaves your phone; Kuier only ever asks for the map of the fixed 8 km block it’s in, or Utrecht’s when it can’t use your location.

What stays on your phone

• Your location. Kuier uses it to plan your walk and guide you along it, on the phone itself. It is never sent anywhere.
• Your walks and the streets you’ve walked, your settings, and the map files Kuier has downloaded.
• Your walk ratings, if you give them. Kuier uses them on this phone to suit your taste; they’re left out of backups and contain no locations or street names. “Forget my walks” deletes them too.
• A short log of what Kuier did, such as when it used location and how long each step of finding a walk took (events, counts and timings only, never coordinates or map squares). It never leaves your phone.
• What it shows on your own devices. The home-screen widget shows today’s walk: its shape, minutes and a note about a landmark. During a walk, the Live Activity shows the next turn, street names and minutes left on the Lock Screen, Dynamic Island and Apple Watch, never an address or coordinates.

If you choose to share a walk, the image shows its route drawn on the surrounding streets, so whoever sees it can tell the area.

Deleting the app deletes everything Kuier stored. Its map files, walk history and log are left out of iCloud and device backups; only your settings (pace, minutes, appearance) go into your own backup, as any app’s do. There is no account, so there is no other copy.

To clear it without deleting the app, tap the gear in Kuier, then “Forget my walks”. That deletes your walks and the streets you’ve walked, your ratings, the saved map files and the log.

Map files

Every map in Kuier comes from tiles.kuier.app, hosted by Cloudflare. The map is split into fixed squares of about 2.7 km, grouped on a fixed grid into blocks of 3×3 squares, about 8 km a side. Wherever you are in a block, Kuier asks for exactly the same files: that block and the ring of squares around it, so there’s map in every direction. The server sees which block’s files are requested and your IP address, as any server would, but never which square you’re in or where you are. The requests carry no account, cookie or identifier.

Downloaded map files stay on your phone. Kuier checks now and then for a new version; about once a month, when one is out, it refreshes them in the background, never during a walk.

Cloudflare may keep standard server logs for security; see Cloudflare’s privacy policy. Kuier doesn’t collect or look at request logs.

No third parties

Kuier contains no analytics, advertising or third-party SDKs. Map data comes from OpenStreetMap and landmark descriptions from Wikidata, both built into the map files ahead of time, so the app doesn’t contact them by itself. The credit links in Settings open their sites only if you tap one.

Apple

Downloads, updates and TestFlight are handled by Apple under Apple’s privacy policy. If you choose to share crash reports or TestFlight feedback with developers, Apple passes them on; they’re used only to fix Kuier.

The map you see during a walk is Apple Maps. It loads map images for the area on screen from Apple, under Apple’s Maps privacy policy. Kuier itself doesn’t send your position to Apple.

This website

kuier.app has no analytics or third-party scripts. A few small scripts run here: one picks today’s ink colour from your device’s date, one moves the highlights as you point, one gets the screenshots ready for dark mode, one remembers your language, and one moves between pages without reloading them. Nothing is sent. Cloudflare serves the site and sees your IP address, as any server would.

The only cookie is lang, set when you pick a language with the flag, so the site opens in that language next time. It holds “en” or “nl”, nothing else, and lasts a year. Your browser sends it with requests to kuier.app, as browsers do, but nothing there reads it.
