Nightkit – CPAP Supply Tracker
Nightkit Privacy Policy
In short: Nightkit does not collect your data.
Updated: 2026-10-04 · Developer: Artem Kolchin
What Nightkit stores
Everything you enter — your mask type and humidifier setting, tracked parts, replacement intervals and dates, spares count, cleaning schedule, history and reminder settings — is stored only on your device, in the app's private storage shared with its widget (an App Group).
What goes over the network
Nothing you enter leaves your device. Nightkit has no server and no user accounts, so we never see your data.
- No analytics, no crash-reporting SDKs, no advertising identifiers, no tracking.
- The only network requests are made by Apple's StoreKit to show prices, process purchases and restore them.
- Links in Settings (privacy policy, support, terms of use) simply open in your browser.
Purchases
Nightkit Pro is sold through Apple's in-app purchase system as a monthly subscription or a one-time lifetime purchase. Payment is handled entirely by Apple; we receive no payment details and no personal information. Apple's handling of this data is described in Apple's privacy policy.
Permissions
Notifications are the only permission Nightkit asks for. Nightkit uses them to remind you when a CPAP part is due for replacement and, with Pro, when it is time to clean. Reminders are scheduled locally on your device; nothing is sent to us or to any third party. You can turn them off at any time in iOS Settings.
Nightkit Pro includes Home Screen and Lock Screen widgets that show the next part due. The widget reads the same on-device data through a shared App Group container; it makes no network requests.
Nightkit does not access your contacts, photos, location, camera, microphone or Health data.
Deleting your data
Open Settings inside Nightkit and tap “Reset all data”, or simply delete the app. Either removes everything Nightkit stored on your device.
Children
Nightkit is not directed at children and collects no information from anyone.
Changes
If this policy changes, the new version will be published at this address with an updated date.
