Privacy policy
G Navigation for Android - version 17, last updated: 2 November 2026.
G Navigation is a navigation app for motorbikes and cars in Vietnam that sends turn directions, maps and calls to your watch. It is developed and run by G Navigation (“we”). This page explains what data the app collects, what it is used 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.
The short version: the app has no ads, uses no advertising identifier, and does not sell or share your data for marketing. Personal account sync is optional and described below. Notifications, contacts, calls, the microphone and the camera are used only when you turn on the feature that needs them.
1. What we collect and why
Account
You can sign in with Google to use Premium, sync data and send contributions. We receive the account ID, display name and email address Google sends; we never receive your password. Each account is used on one phone at a time.
Account sync (optional)
You choose to enable and confirm sync. If your account already has synced data, it can be restored automatically when you sign in on a replacement phone.
G Navigation stores favourites, Home/Work, selected-place history, saved text notes, personal preferences, and offline map areas' names, locations and extent on Cloudflare infrastructure to sync and restore data for your account.
This copy excludes live GPS streams, active routes, audio or recording sessions, sign-in credentials, Premium state, pairing and permissions. Pairing, permissions and downloaded map files stay device-specific; restored offline areas need downloading again.
Location
Location is sensitive personal data under Decree 356/2025/ND-CP. The app asks for precise or approximate location and uses it in two ways; you can turn all of it off in Android settings:
- On the device: to show where you are on the map, compare your speed with the limit and guide you turn by turn. While you navigate, the app keeps reading your location in the background so directions are not lost when the screen is off; background location is optional and asked separately.
- Sent to the server per request: the map area in view, to return the map, signs, cameras and speed limits around it; your start, destination and vehicle, to plan a route; your location and heading, to reroute when you leave the route; your current location with what you type, to rank search results by distance. These requests are answered, and that is all; the server keeps no movement history linked to you. Location and speed during a trip, without your account, are also used to improve routing and arrival times.
Current weather
Only while you navigate, the app sends your current GPS location, rounded to two decimal places, directly over HTTPS to MET Norway to get the weather there. MET receives the coordinates, IP address and app identification; this request sends no account information or complete route.
Voice search
When you tap the microphone, your speech is turned into text on the phone; only if you pick an online recogniser is the audio sent to it, under its own policy. We receive only the resulting text, never a recording, and keep no recording. The app listens only while the microphone is open.
Community reports
The signs, cameras and incidents you send are stored with their location and time of sending, and any photo or note, for us to moderate and show to other riders; photos have the information embedded in the file, such as where they were taken, removed. The app sends only what you save or report yourself; sending comes with this policy, which you accept when you install or update the app, with no separate switch. By submitting, you allow G Navigation to store, check, edit and share the road-sign content to provide and improve the map data.
Google Maps
Only when you open the Traffic and incidents screen (not used while navigating): the Google Maps SDK shows the map, satellite imagery and traffic from Google Maps together with users' incident reports; Google Maps receives your IP address, device data and map gestures. Places you search for or long-press to pick are routed on the app's map.
Watches and calls
Directions, the map and caller names go to the watch you paired over Bluetooth and the watch maker's app, not through our servers. These features are off until you turn them on:
- Notification access: reads Google Maps guidance, and caller names and call state from Zalo, Messenger, Telegram, Viber, Instagram or LINE, to show them on the watch. Unrelated notifications are ignored; message contents are not stored or uploaded.
- Contacts and Phone: creates temporary contacts carrying the caller's name so the watch shows it, and knows when a call is ringing. The app uploads no contacts, places no calls, and never listens to or records calls.
- Voice replies: speech from the watch's microphone is recognised on the phone (or by an online recogniser if you pick one) and the reply is sent through the messaging app. Nothing is recorded.
- Camera: only when you photograph a sign or an incident.
The G Navigation app for Wear OS on the watch uses notifications, full-screen, vibration, network and (optionally) the Phone permission to answer calls on the watch; it does not use the watch's location, microphone or contacts.
Purchases
Payments are handled by Google Play. We receive only the product ID and purchase token to grant and restore Premium, never card details.
Technical data
- Abuse prevention: the number of search and route requests per account (counted with a hash, not the account ID), and the IP address at the network service in front of our servers. Used to limit request rates and temporarily block accounts that scrape data automatically.
- Device attestation: a check that requests come from the official app, with a hashed device identifier to stop repeated trials. We receive only a valid / not valid result.
- Notifications: an installation ID and messaging token of the platform's push notification service, to deliver update and service notices.
- Update checks: the app asks the G Navigation server about new versions of the app and the watch apps; the requests carry no account.
- Error reports: technical logs stay on the phone; a report is sent only when you tap Send and confirm, and the app never sends one by itself.
- Guidance voice: the G Navigation voice speaks directions on the phone, after its voice package is downloaded once. If you pick an online system voice, guidance sentences may be sent to that voice's provider.
2. What we do not collect
- SMS messages, the call log, calendars, photos or files unrelated to data you provide through the features above. The app never listens to or records calls.
- Advertising identifiers, tracking cookies, data from data brokers.
- Payment card details - payments are handled by Google Play.
3. Who processes data for us
Our servers are run by us. Some work needs outside services; each receives only the data that work needs, always over HTTPS:
| Service | What it receives | What for |
|---|---|---|
| Map service | IP address, the map area in view | Showing the map (data © OpenStreetMap contributors) |
| Google Maps | IP address, device data, map gestures on the traffic screen | Map, satellite and traffic view |
| Search and routing services | Start, destination, vehicle; search text and approximate location | Planning routes, speed limits and cameras; returning search results |
| MET Norway | Current GPS coordinates rounded to two decimal places, IP address, app identification | Returning weather at your current location while you navigate |
| Sign-in with Google | Sign-in identity | Signing in |
| Google Play | Product ID, purchase token | Buying and restoring Premium |
| Platform services | Device attestation result; notification token | Device attestation; sending notifications |
| Network service in front of our servers | IP address, connection information | Securing connections, stopping attacks |
| Moderation tool | Photos, notes and location of incidents sent or reported | Moderating content |
| The watch maker's app | Directions, the map, caller names; speech when voice replies are on | Showing them on your watch |
| Online speech recogniser (optional) | Audio while you speak, only when you pick it | Speech recognition |
| G Navigation server (Cloudflare infrastructure) | The sync data listed above, linked to your account | Sync and restore account data when you use this feature |
Route and search requests passed to outside services carry no name, email or account ID. Some services may process data on servers outside Vietnam; we send only the data the feature you use needs. We provide data 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, sign in on another phone or delete your account |
| Location, route and search requests | They are answered; the server's operational logs are kept only briefly for troubleshooting |
| Weather results in the app | Only in memory to reduce repeated requests; no weather history is written to storage |
| Weather request logs at MET Norway | MET logs the IP address and requested coordinates in Oslo, Norway. Processing and retention follow MET's own policy. See MET's data terms and the policy linked above. |
| Speeds on roads (no account attached) | 14 days; after that only averages remain |
| Abuse-prevention counters | They expire after 2 to 7 days |
| Incidents you report and their photos | The incident expires, within hours |
| Sign and camera reports | 60 days; camera and speed-limit points shared from routes up to 90 days; approved signs stay as map data, without your account |
| Hashed device identifier (not linked to the account) | Up to three years, to stop repeated trials |
| Purchases | As long as needed to grant and restore Premium and meet transaction obligations |
| Notification token | It is deleted; the push service may take up to 180 days to remove it fully |
| Error reports you send | Up to 90 days |
| Active route and data on your phone | Until you delete them or uninstall the app; the server's sync copy has the separate retention above |
| Account sync copy (optional) | Kept until you delete your account. Turning sync off stops sync; it does not delete the copy already on the server. |
| Temporary caller-name contacts | Removed after the call; for Huawei watches, deleted after 30 days without a call |
| Technical logs on the phone | Size-limited; call logs are cleared after 48 hours |
The app turns off Android system backup. Optional account sync above is a separate feature.
5. Your rights
- See and delete: saved places and search history, in the app; temporary contacts with the “Delete the contacts G Navigation made” button.
- Withdraw consent: turn contributions or speed sharing off in the app; turn off location, microphone, camera, contacts, notification or Bluetooth access in Android settings. Navigation keeps working when you decline optional permissions.
- Delete: individual saved places, or your whole account (section 6).
- 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 account. Your account and sign-in sessions are deleted, the signs and cameras you sent are kept anonymously and no longer linked to you, and your notes and name are taken off incidents. No longer have the app installed? Email support@gnavigation.men with the subject “G Navigation account deletion” and the email you sign in with; we may verify that you own the account and handle it within 30 days. Deleting the account does not reset trial eligibility on the same device.
Deleting your account removes synced content from the server. A technical marker linked to a hashed account identifier, without synced content, is kept without a time limit to block delayed old requests.
7. Security
Every connection is encrypted (HTTPS). Service keys live on our servers, not in the app, and each account has only one active sign-in. 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 driving or riding 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
G Navigation (com.gnavigation.mobile). Email: support@gnavigation.men
G Navigation is developed independently and is not affiliated with Google or Huawei; the Google Maps name in the app only identifies that app.
10. Changes to this policy
When this policy changes, we update this page and the date at the top. Changes that increase the data collected or its uses are announced in the app and, for sensitive data, your consent is asked again before they take effect.
