VọtPrivacy Policy
Last updated: 10 September 2026. Applies to the iOS app "Vọt" (bundle vn.vot.app) and its backend. This is an English translation; the Vietnamese version prevails in case of conflict.
1. Who we are
Vọt is developed and operated by LNH Soft ("we"), Hanoi, Vietnam, contact [email protected]. We are the data controller for the data described here. Vọt is an independent third-party app, not owned by or endorsed by any vehicle manufacturer.
2. What we collect and why
We collect only what the app needs to work. No advertising, no behavioural analytics, no data sales.
| Data | When | Used for | Stored where |
|---|---|---|---|
| Email address | Sign-up, or sign-in with Apple/Google | Account identity, verification and password-reset codes | Our server |
| Display name (optional) | When you enter it, or supplied by Apple/Google at sign-in | Shown inside the app | Our server |
| User identifier | Generated at sign-up | Linking data to your account | Our server and the device Keychain |
| Phone number (optional) | Only if you add it | Account recovery, SMS verification | Our server |
| Precise location | While using maps, charger search or navigation, and only while the app is open | Finding nearby chargers, computing routes | Sent per request; no location history is stored |
| Assistant questions | When you ask the assistant | Answering your question | Sent to our server and a language-model provider; no history stored |
| Text read aloud in a paid voice | Only when you have bought and selected a paid voice | Turning the assistant's replies and navigation prompts into speech | Sent to our server and a speech synthesis provider. The server may keep it in memory for up to 1 hour to replay an identical sentence; it is never written to a database |
| Purchase records | When you buy Vọt Premium or a paid voice package | Validating the transaction with Apple, keeping your entitlement | Transaction ID on our server; no card details |
| Push notification token | When you enable notifications | Charging and account notifications | Our server and Apple Push Notification service |
We do not collect contacts, photos, voice recordings (when you ask the assistant by voice, Apple's speech recognition turns your words into text — on your device or on Apple's servers — and only that text reaches us),health data, advertising identifiers, or any data used to track you across other apps and websites. Favourite places, search history, settings and vehicle data stay on your device.
If you record your own voice so the app can read aloud in it, the recording and the voice features computed from it are stored only on your iPhone. They are excluded from backups and never sent anywhere. Downloadable voices come from our content server and run entirely on your iPhone.
3. Signing in with Google and Apple
When you choose "Sign in with Google", Vọt requests exactly three basic scopes: openid, email, profile. We receive, and only receive:
- your Google account email address and whether it is verified;
- your public display name;
- your Google user identifier.
We use this data only to create your Vọt account, recognise you on subsequent sign-ins, and contact you about your account. We do not access Gmail, Contacts, Google Drive, Calendar, Photos, YouTube or any other Google service; do not read, write or delete anything in your Google account; do not use Google data for advertising; do not transfer Google data to third parties beyond the processors listed in section 4; and do not use Google data to train AI models.
Vọt's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
Sign in with Apple works the same way and yields the same categories of data. If you choose "Hide My Email", we only ever receive the relay address Apple generates.
You can revoke access at any time at your Google account permissions page or in iPhone Settings → Apple ID → Sign in with Apple. Revoking access does not delete your Vọt account — see how to delete your account.
4. Who receives data
- Vọt's server (located in Vietnam): everything in the table in section 2.
- Map and charger data providers: coordinates and search terms.
- Language-model provider: your question plus the vehicle/charger context needed to answer it.
- Speech synthesis provider: the text to be read aloud, only when you have bought and selected a paid voice.
- Street imagery provider: charger coordinates.
- Email and SMS providers: your email address or phone number, to deliver verification codes.
- Apple: payment processing for Premium and voice packages, push delivery, and speech recognition when you ask the assistant by voice; we never see your payment details and never receive the audio of your voice.
These parties receive only the data needed for a specific request and may not use it for their own purposes. We do not sell or share personal data for advertising.
5. Storage and security
- All app-to-server traffic is encrypted (HTTPS).
- Passwords are hashed with Argon2id; we cannot read your password.
- Verification codes are stored hashed and expire after 15 minutes.
- "Sign out of all devices" in the app terminates every session.
- Account data is kept until you delete your account.
6. Your rights
- View and edit: email, name and phone number under Settings → Account.
- Delete your account: available directly in the app; all server-side data is permanently erased. Steps at delete account.
- Withdraw location, microphone or notification permission: iPhone Settings → Vọt.
- Other requests (data copy, complaints): email [email protected]; we respond within 30 days.
7. Children
Vọt is for drivers and is not directed at anyone under 16. We do not knowingly collect children's data.
8. Changes
When this policy changes we update the date at the top and, for significant changes, notify you in the app.
