Privacy Policy
Last updated October 3, 2026.
1. The short version
Nydus collects nothing about you. No account, no analytics, no cookies, no location tracking, no ads. The only thing the app stores is your own settings, on your own device.
2. What we collect
Nothing you give us. There are no accounts, no forms, no analytics, no advertising SDKs, no fingerprinting, nothing that follows you across the web — and you never type, upload, or send us personal information. Even our fonts are hosted on our own servers: we don't load Google Fonts or any other third-party assets that could let someone else profile our visitors. (What our hosting infrastructure necessarily observes in order to serve traffic — IP address, requested URL, time — is disclosed in §5.)
3. What stays on your device
Your preferences — region, language, direction, display settings, and which hints you have dismissed — are saved in your browser's local storage. The card you currently have open is remembered in session storage (cleared when you close the tab), and the app's offline files live in your browser's cache storage. All of it stays on your device; none of it leaves your phone or computer.
4. How your data reaches you
Wait times, camera snapshots, and weather are fetched for you by our servers, not by your device directly. CBP, CBSA, transportation agencies, and camera operators see our servers' requests, never yours: your IP address and location are never sent to them. Weather is looked up for each fixed border crossing, never for where you are.
5. What the infrastructure sees
Nydus runs on third-party hosting infrastructure. Like any hosting provider, our infrastructure necessarily observes basic request metadata — IP address, requested URL, time — in order to serve the traffic. Our own code logs nothing; retention of this metadata is governed by the providers' own policies.
6. When you leave Nydus
Tapping Navigate opens Apple Maps or Google Maps with the crossing's coordinates; from that moment their privacy policies apply. Sharing a crossing uses your device's share sheet and goes wherever you choose to send it.
7. Installing the app
On iPhone, adding Nydus to your Home Screen happens entirely on your device. On Android, installing through Chrome asks Google to build the app package one time (and to re-check the app's manifest periodically). Nydus itself still collects no data. The version of Nydus distributed through the Google Play Store is the same app and collects nothing beyond what is described above; Google's store services operate under Google's own privacy policy.
8. Changes to this policy
We may update this policy from time to time. The "last updated" date above will always reflect the current version.

Questions about this policy: [email protected].
10. Canadian users
Nydus serves travelers on both sides of the border. We handle personal information in line with Canada's PIPEDA and Quebec's Law 25: we collect as little as possible (see above), use it only to operate the app, and you can reach us at the address above with any privacy question or request.
