Privacy policy

Scope

This policy covers MapCar for head units, Android phones, iPhone and MapCar Launcher, including use through Android Auto and CarPlay. The provider is Z-SOFT CO., LTD.

Data on your device

Trip history, saved places, familiar routes and speed-limit corrections are stored on your device. MapCar does not upload your complete trip history. Address lookups and route requests may use the locations needed for those requests.

If you use the Maintenance reminder, your vehicle distance, service interval and the distance driven in each 15-minute period (no location) are stored on our system with your device ID, so linked devices can share them and reinstalling does not lose them.

MapCar keeps a recent drive trace (GPS position and where the car icon was drawn, about once a second) on the device to diagnose road-snapping problems; only the last 20 trips are kept and you can turn it off in Settings › Map. It leaves the device only when you tap “Send drive trace” or agree to send road-snapping data as described below.

Camera images for sign recognition and distance alerts are processed on your device. Photos and videos are saved when you capture them or enable dashcam recording. You can delete or share them yourself. Sign reports do not include camera images. Vehicle and tyre-pressure readings are also processed on your device. MapCar Launcher accesses music files for playback and, with notification access, displays and controls the current track.

Connected features

Maps, place search, routing and alerts use the map area, search text, vehicle location, start, destination and waypoints needed for the feature. Route requests are not retained. Location-based alerts continue to download when the community map is off.

When you use place photos, radio or other online content, the content service may receive your IP address and the information needed to fulfil the request. Its own policy also applies.

Community map

The community map is on by default and can be disabled in Settings. When enabled, MapCar sends your reports, camera-recognised signs, traffic speed samples and route-choice information to improve traffic updates and route suggestions. This may include location, direction, report type, speed, technical information and a device identifier, but not your complete trip history.

Sharing unmapped roads requires a separate opt-in on supported versions. Submissions include road segments, movement information and a device identifier, with areas near the start and end removed before sending. Other users cannot see your device identifier.

Road-snapping improvement data

Only if you agree (the app asks once; change it any time in Settings › Map), MapCar sends about one minute of the drive around a moment the car icon left the road or jumped: GPS position, speed, heading, location source and where the car was drawn, with the app version and device model. Whole trips are never sent; the parts within 300 m of the start and end of every trip are removed before sending. It is stored with a hashed device code, not linked to your account or activation code, and used only to fix road snapping. Alongside, the app sends the total distance (km) and time (minutes) driven while monitoring — no position, no time of day — to compute incidents per 100 km for each app version. Some incidents are moved to a random place and time (about 50–150 km away) so they no longer point to the real place or moment, and are then kept longer as an internal test set.

Convoy

Convoy works only when you create or join a convoy with a code. Your location, heading and speed are sent to its members only after you agree to share, including while the app runs in the background, and you can turn this off at any time. The server keeps only your latest position for up to 10 minutes, deletes it as soon as you stop sharing, and keeps no route history. The name you choose and the member list are kept with the convoy to operate it and prevent abuse, and deleted 30 days after the convoy ends.

Convoy messages, photos and voice messages are encrypted in transit and only relayed to members: the server does not store this content. It is stored only on each member's device, up to the latest 200 messages and 30 photos, and deleted automatically when you leave or are removed, or when the convoy ends or expires. If you tap Report, that message or a thumbnail of that photo is sent to MapCar with both names so we can handle the violation.

Voice and Mika

The microphone is used when you activate a voice feature. Recognition takes place on the device or online, depending on the device and feature. On some Android devices, a command recording is sent for transcription and then discarded. The iPhone version does not send audio to MapCar.

Mika uses your question and relevant context, such as location, speed, heading, road name, speed limit, vehicle type, destination, saved places and language. Online processing may be performed by service providers on behalf of Z-SOFT, including outside Vietnam. MapCar does not retain question or answer content or audio recordings. Usage and credit records are retained to manage your plan.

Custom greeting text is used to generate audio. The server holds the text and audio only temporarily to deliver them to your device, does not share them with other users, and removes them within about 24 hours, usually right after download.

Device, purchases and support

MapCar does not require an account. A device identifier and technical details, such as app version, operating system and device model, support trials, purchases, contribution checks, data protection and troubleshooting. The identifier may persist after reinstallation. MapCar does not use advertising identifiers.

Purchase and restoration records identify the transaction, plan and device to confirm access. App-store payments follow the store’s policies. Bank transfers on supported versions require order and bank transaction information for reconciliation and refunds.

When you contact support, we use your message and contact details to respond. IP addresses and access logs may be used for service security and troubleshooting.

Retention

Device records are kept while the app remains in use. Raw community reports are cleaned up periodically with a target of 12 months; compiled signs are retained while relevant. Temporary incidents expire after 30–60 minutes, traffic samples after 10 minutes and route-choice records after 12 months. Raw unmapped-road submissions are cleaned up with a target of 30 days. Road-snapping improvement data is cleaned up with a target of 30 days.

The latest location used for abuse prevention is retained for one day. Data delivery records may be kept to protect licensed use. Plan, transaction and usage records are retained for the plan duration and accounting obligations.

Your choices

Turning off the community map in Settings stops contributions, traffic samples, route-choice sharing and community report downloads. Place photos and unmapped-road sharing are off by default. Mika, radio and online content are used when you choose those features. Sending road-snapping improvement data is on only if you agree and can be turned off at any time; turning it off deletes incidents not yet sent from the device.

You can manage location, camera, microphone, speech recognition, notifications, photos, Bluetooth and local-network permissions in your device settings. Some versions also need background access, overlay, music or update-installation permissions. Denying permission may prevent the related feature from working. MapCar has no advertising, does not track you across apps and does not sell your data.

Deletion and contact

Delete history, saved places, downloaded data, photos and videos in Settings or the relevant screen. To request deletion of data linked to your device, copy its identifier from Settings and use the Delete data page or email support@z-cloud.com.vn. We process requests within 30 days. Transaction information required for accounting and active activation codes are retained until the relevant obligations end.
