Privacy Policy
Border Days (Border Days: Visa Day Counter) · Effective November 12, 2026
Updated for Border Days 1.0
The short version: Border Days collects no data. Your stays stay on your device. There is no account, no servers, no analytics, no advertising, no tracking and no third-party SDKs.
Data we collect
None. In App Store terms: Data Not Collected. The app has no account, no servers, no analytics, no advertising, no tracking and no third-party SDKs. Agentic Quarks never receives your location, your stays, your passports or how the app is used.
Your location stays on the device
Automatic tracking is optional. If you turn it on, Border Days uses low-power location (significant location changes and visits, not continuous GPS) and a map of every border that is stored inside the app, so your position becomes a country on your iPhone, offline. The location is used only for this lookup. Coordinates are not stored and never leave your iPhone: only the country and the day are saved, as part of your stays. You can choose "While Using" or "Always" when iOS asks, and you can change or revoke the permission at any time in iOS Settings. You can also leave location off and add your stays by hand.
What stays on your device
Your stays, passports and settings are stored only on your device. Border Days 1.0 does not sync to iCloud. If you export a file of your stays, it goes where you choose, such as Files or iCloud Drive, and from then on it is under your control. The same goes for a PDF travel report: it is made on your device from your stays, Border Days does not send it anywhere, and what you do with it is up to you. Deleting the app deletes all its data.
Notifications
The alerts before your leave-by date and when you cross a border are local notifications scheduled on your device. They do not use a server or a push service, and iOS asks your permission first. You can turn them off in iOS Settings.
Purchases
Border Days Pro and its free trial are handled by Apple through the App Store. Agentic Quarks receives no payment details or personal information.
Links to official sources
Each rule links to its official government source. These links open in your browser, and Border Days sends nothing with them.
Children
The app is not directed at children. It collects no data from anyone, including children.
Changes and contact
If a future version ever changes any of this, this page will say so before that version ships. Questions? Email borderdays@agenticquarks.com. Border Days is made by Agentic Quarks, LLC.
