Privacy policy
Last updated 5 October 2026
1. Who we are
The Nudgent app is provided by Nudgent ("we"). Registered address: [registered address]. Contact: [privacy contact email]. We are the controller of the little information that reaches us (the server logs of the registration lookup, of the card page and of the carers' guide website, described in section 5). For the data described below that stays on your devices, you are in control of it and we do not receive it.
2. The short version
- There are no accounts. Your information is stored on your iPhone (and, where you choose, on your Apple Watch and your emergency card).
- We do not sell your data, show ads, or use tracking or analytics inside the app.
- Some features contact other services to work (listed in section 5). We say exactly what is sent.
3. What the app handles
| Information | Why | Where it lives |
|---|---|---|
| Location and speed | Speed limits, trips, navigation, parking, toll and charging-zone detection | On your phone |
| Trip history | Your trip log and exports | On your phone |
| Vehicle and exemption details (registration, Blue Badge, tax class) | Working out which charges apply to you | On your phone |
| Medication names, doses and times | Reminders and dose logging | On your phone. If you use the Apple Watch app, your Watch also receives the medication names, when each was last taken and whether it is due, overdue or too soon (not the doses) |
| Heart rate, heart-rate variability, blood glucose (from Apple Health or your Nightscout site) | Showing changes against your own normal and optional alerts | Read from Health; processed on your phone |
| Live heart rate from your Apple Watch during a drive you start in Nudgent (once you have allowed it in Health on your Watch; it can be switched off in the Watch app) | Noticing a rise in heart rate while you are driving, and showing it on your Watch and phone | Sent from your Watch to your phone and held in memory. Nudgent does not save the stream |
| Heart-rate alert history | When an alert fires, the app keeps a record of that moment (time, heart rate, how it compared with your usual, whether you were driving, and your own reply) so you can see which alerts were useful | On your phone. It is removed when you delete the app |
| Emergency profile and emergency contacts | Your NFC emergency card | On your phone and on the card you write |
| Bluetooth tracker names and signal strength | Finding and warning about items you track | On your phone |
| Person tag (optional): the name you give the person, the tag's Bluetooth identifier, its battery level if it reports one, whether it is in range and when it last was, whether you recorded that they agree or that you are acting in their best interests, your alert settings, and, if you choose it, the position of your home | Telling you when the tag goes out of range, and asking you to review from time to time whether it is still wanted | On your phone. Not sent to us, and not shown in Live Activities or on the Watch app |
| Where your phone was when the person tag was last in range (latitude, longitude and time). While the tag is with your phone this is replaced about once a minute, and it is kept until you delete the tag | Showing you where to start looking. It is your phone's position, not the person's | On your phone |
| AirTag items (the name you type) | A reminder with a shortcut that opens Apple's Find My app. Nudgent cannot see an AirTag or where it is | On your phone |
Health, medication and disability-related information is special category data. We process it only with your explicit consent, which you give by switching a feature on and granting the permission, or by choosing to enter the information yourself (for example a medication, or your emergency card details). You can withdraw consent at any time by switching the feature off, revoking the permission in iOS Settings, or deleting the app.
A person tag records information about someone else, and the fact that they are being watched over can reveal a health condition. Set one up only with their agreement or, if they cannot decide this for themselves, in their best interests. The app asks you to say which, and to review it from time to time. That decision is yours: it is made on your phone and we never see it.
4. Permissions
The app asks for location (including "Always", so trips, tolls and guidance work with the screen off, and so a person tag can note where your phone was when the tag was last in range and whether your phone is at home), notifications, Bluetooth (kept connected in the background to watch a person tag), Apple Health, and NFC. Each is optional and the related feature simply stays off without it. A person tag cannot alert you without Bluetooth and notifications.
Apple Health: Nudgent reads heart rate, heart-rate variability and blood glucose. The Apple Watch app can also run a short workout session during a drive to get a live heart rate, which asks for permission to save workout data to Health. Nudgent does not keep that workout, but some heart-rate readings from it may stay in Apple Health, where you can see and delete them.
Notifications, the lock screen and your Watch: by default, notifications and Siri's "am I ready to drive?" answer are kept general (for example "Time for your medication" and "Nudgent has 2 things for you to check"). They do not include medication names, glucose numbers, your plans or the name of someone you watch over with a person tag unless you switch on "Show details on the lock screen" in Settings. Some things still show: alert titles say what kind of alert it is (for example "Glucose low", or "Your person tag is out of range", which tells anyone who reads it that you are watching over someone), and when you ask Siri to log a dose, your unlocked phone replies with the medication name. With that setting on, a person tag's alert also shows the person's name and when the tag last connected. iOS may show your notifications on a paired Apple Watch too.
The Live Activity on the lock screen shows speed and the limit during a drive and, while you are navigating, the next turn (which can include a street name) and your arrival time. It never shows health or Blue Badge information. The Watch app shows the same driving information and, unless you turn it off in the Watch app, your live heart rate and a "heart rate is up" nudge. Away from a drive it shows your medication names and status, your own written plan, and a general calm level. Person tag information is not shown in a Live Activity and is not sent to the Watch app.
5. What leaves your phone
| Feature | What is sent | To whom |
|---|---|---|
| Automatic road type (can be switched off in Settings) | Your exact latitude and longitude, and your IP address, roughly every minute or every 50 m, only while you are moving faster than about 5 mph, a trip is being recorded, or you are navigating (the app cannot tell driving from being a passenger or cycling). The "30 m" in the request is the search radius, not a limit on precision | OpenStreetMap's Overpass service (overpass-api.de). See their privacy policy |
| Navigation and place search | Search text, your current area (so results are nearby), your start and your destination, and the map area you view | Apple Maps (Apple) |
| Registration check | The registration you type, only when you press Look up | Our lookup server (hosted on Vercel), which forwards it to the DVLA. We do not store or log registrations. The host sees your IP address, which the server uses to limit abuse |
| Person tag map | The map on a person tag's screen loads Apple Maps for the area around where your phone was when the tag was last in range. If you tap "Open in Apple Maps", that position goes to Apple Maps, labelled "Where the tag was last in range", to give you walking directions | Apple Maps (Apple) |
| Carers' guide website | Nothing from the app. If you open a guide page, it is loaded from our host (Vercel), which can see your IP address, device type and which page you opened. The pages set no cookies, use no analytics and load nothing from other sites. The printable information sheet has no way to send what you type: it stays in your browser and is lost when you close the page, so print it first | Vercel (page host) |
| Open Find My (AirTag items) | Nothing. The button only opens Apple's Find My app on your phone | Not sent to us or anyone else |
| Nightscout glucose (optional) | A read request with the access key you enter | Your own Nightscout site. The key is kept in the iPhone Keychain |
| Subscriptions | Purchase details | Apple (we never see your payment details) |
| NFC card page | Nothing from the card's contents. They are in the part of the web address after "#", which a browser never sends to a server, and they are decrypted on the device reading the card. The page itself is loaded from our host (Vercel), which can see the reader's IP address and device type, as any website can | Vercel (page host) |
| Apple Watch and Live Activities | Speed, the limit, turn directions and arrival time, the parking timer, medication names and status, your own written plan, and a general calm level (including whether your HRV is below your usual), between your phone and your own Watch. Live Activities and notifications are delivered on the device | Not sent to us or anyone else |
The services above have their own privacy policies and some run outside the UK (for example in the EU or the US) under their own safeguards. Overpass is at overpass-api.de.
6. The NFC emergency card
Your name, date of birth and emergency contacts are readable by any phone that taps the card (the web page shows your age, but the date of birth is on the card itself). Your medical details are encrypted with your password and are only readable with it. Anyone holding the card can copy it and try to guess the password offline, so use the password Nudgent suggests, or a long random one. We never receive the contents of the card, but because the card page is loaded from our host, we cannot say that nobody can see that a card page was opened (the host sees an IP address and device type).
7. Keeping data
Data stays on your devices until you delete it or delete the app. In the app you can delete trips, medications, trackers (deleting a person tag also deletes the person's name, the saved positions and the home position), checklist items and toll records, and change or clear your emergency profile. Other records, such as parking history and heart-rate alert history, are removed when you delete the app. Copies in your own iPhone or iCloud backups stay until you delete them or they expire, and notifications that have already arrived stay in Notification Centre until you clear them. Trip history older than 30 days is hidden on the free plan, not deleted.
8. Your rights
Under UK data-protection law you can ask to access, correct, delete or move data we hold about you, and to object or complain. Because the app's data is on your devices, you can see most of it in the app and delete it as described in section 7, or delete the app to remove everything. For anything else, contact us above. If you are the person being watched over and want it to stop, ask the person who set it up: the information is on their phone, and we cannot see, change or delete it. You can also complain to the Information Commissioner's Office (ico.org.uk).
9. Children
Nudgent is not aimed at children under 13. It is for adults who drive and for adults who look after someone.
10. Security
Health, profile and person tag data (including a person's name and saved positions) stay on your devices and rely on iOS protection. Your own iPhone and iCloud backups may include them, so keep your Apple account and passcode secure. Secrets such as access keys are kept in the iPhone Keychain. No system is perfectly secure.
11. Changes
We will update this page and the date above if this policy changes.
