Privacy policy
G Navigation for iPhone - last updated: 5 November 2026.
G Navigation is a navigation app for motorbikes and cars in Vietnam that sends turn directions to your watch. It is developed and run by G Navigation (“we”). This page explains what the app collects, what for, how long it is kept, who can see it and how you control it. This policy follows Vietnam's Personal Data Protection Law No. 91/2025/QH15 and Decree 356/2025/ND-CP.
In short: the app has no ads, uses no advertising identifier, and does not sell or share your data for marketing. Our servers do not keep your movement history.
1. What we collect and why
Account
You use the map, search and navigation without an account. Only to contribute signs, cameras or incidents do you sign in with Apple or Google; we receive the account ID, name and email the provider sends. With Apple, if you hide your email, we receive only the relay address. We never receive your password and do not access your contacts.
Location
The app asks only for location “While Using the App”, never “Always”, and uses it in two ways:
- On your iPhone: to show where you are, compare your speed with the limit and guide you turn by turn. During a trip you start, the app keeps reading your location with the screen locked so directions continue, and stops when you end the trip.
- Sent per request: your start, destination and vehicle to plan a route; your current location with what you type, to rank search results near you; the map area in view to load the map, signs and speed limits. These requests are answered and that is all.
Community reports
The signs, cameras and incidents you send are stored with their location, time and any photo or note, to be moderated and shown to other riders. Photos have the information embedded in the file, such as where they were taken, removed. Incidents are deleted when they expire. Manual reports are sent when you save or report them yourself; sending comes with this policy, with no separate switch.
Purchases
Payments and the free trial are handled by Apple. We receive only the status of your plan, never card details.
Technical data
- Abuse prevention: the number of requests per account, or per iPhone when you are not signed in, over a short time and the IP address, to limit request rates and block automated scraping.
- Device attestation: confirming requests come from the official app on a real iPhone. When you are not signed in, the app uses a random key your iPhone creates and Apple attests, not linked to any name, email or account. When you are signed in, each account is used on one iPhone at a time.
- Notifications: a notification token, only if you allow notifications.
- Error logs: only when you choose to send them for support; without your account or coordinates.
Watch
Directions and the map go to your watch over Bluetooth and the watch maker's app you paired, not through our servers.
2. What we do not collect
- Contacts, calendars, your photo library, the microphone, Health data or files on your iPhone. The camera is used only when you photograph a sign or an incident.
- Advertising identifiers, tracking cookies, behavioural analytics, data from data brokers.
- Payment card details.
3. Who processes data for us
Some work needs outside services; each receives only the data that work needs:
| Service | Receives | For |
|---|---|---|
| Map service | The map area in view | Showing the map |
| Search and routing services | Search text, start, destination, current location, vehicle | Finding places, planning routes, speed limits and cameras |
| Sign-in provider (Apple or Google) | The sign-in you choose | Signing in |
| The platform's notification service | A notification token | Sending notifications you allow |
| Server and network services | IP address, connection information | Running our servers, securing connections, stopping attacks |
| Moderation tool | Photos, notes and location of reported incidents | Reviewing reported content |
| The watch maker's app | Directions and the map | Showing them on your watch |
Search and routing requests sent to outside services carry no name, email or account ID. We provide data to authorities only on a lawful written request under the law.
4. How long we keep data
| Data | Kept until |
|---|---|
| Account (account ID, name, email) | You delete your account |
| Sign-in session | You sign out, change iPhone or delete your account |
| Your iPhone's attestation key when not signed in | Carries no name, email or account; kept to recognise an attested iPhone |
| Location, search and routing requests | They are answered |
| Incidents you report and their photos | The incident expires, within hours |
| Reports and photos you save | Up to 60 days; approved signs stay as map data, without your account |
| Error logs you send | Up to 90 days |
| Notification registration | You turn notifications off |
| Saved places, search history | Only on your iPhone, until you delete them |
5. Your rights
- See and delete: saved places and search history, in the app.
- Withdraw consent: turn off location, camera, Bluetooth or notification access in iPhone Settings.
- Delete: delete your whole account (section 6).
- Questions or complaints: contact us as in section 9, or as the personal data protection law provides.
6. Deleting your account
In the app: Settings → Account → Delete contribution account. Your account and sign-in sessions are deleted and Sign in with Apple is revoked; the signs and cameras you sent are kept anonymously, no longer linked to you. No longer have the app? Email support@gnavigation.men; we handle it within 30 days.
7. Security
Every connection is encrypted (HTTPS). Our servers accept requests only from the official, attested app, and your sign-in session or device pass is kept in the iPhone's Keychain. We access personal data only to handle your requests or moderate reports. No way of sending or storing data is perfectly secure; if an incident affects your data, we will notify you as the law requires.
8. Children
G Navigation is for people riding or driving and is not directed at anyone under 16. If you are a parent or guardian and know your child created an account, contact us and we will delete it.
9. Contact
