Privacy Policy
This policy explains what information Lungdei collects, why, who we share it with, and the choices you have. Calls on Lungdei are fully anonymous by design: we never show your name, phone number, birth date, gender, age, or community to the person you're matched with. Gender, age and community are collected at onboarding, used only to power premium-tier match filtering, and shown back to you on your own You tab — never to anyone you call. This policy describes exactly what we still need to collect to make the app work safely.
1. Information we collect
| Data | Why we collect it |
|---|---|
| Phone number | To create and sign in to your account (SMS verification). Never shown to anyone you're matched with — only a masked version is shown to you, on the You tab. |
| Date of birth | To verify you're 18 or older. The date itself is never shown to anyone, including other users; only your age (a number) is derived from it. |
| Age (derived from date of birth) | Never shown to whoever you're matched with. Shown to you on your own You tab, and used to match you against another person's age-range filter if you're on the premium tier. Free-tier matching never uses this. |
| Gender | Never shown to whoever you're matched with. Used to match you against another person's gender filter if you're on the premium tier — free-tier matching never uses this — and to show your pronoun on your own You tab. |
| Community | Never shown to whoever you're matched with. Shown to you on your own You tab, where you can change it at any time. Also used to match you against another person's community filter if you're on the premium tier; free-tier matching never uses this. |
| Account ID (a Firebase user ID, not your phone number) | Internal identifier used to run matching, calls, blocking, and reports. Not shown to the person you're matched with; if you block someone, they appear as a numbered entry (never their name or account ID) in your own You → Blocked people list so you can manage it. |
| Blocked-user list | So we can keep you from ever being matched with someone you've blocked. |
| Reports you file, and reports filed against you | To review and act on abuse (see Terms). The reason you selected and the call it relates to are recorded; the person you report is never told who reported them. |
| Call history (call type, length, and time — never who you talked to) | So you can see your own recent call activity in the app. You can turn this off on the You tab, and it never includes any identifying detail about the other person. |
| Crash and diagnostic data | Automatically collected by Firebase Crashlytics (crash reports, device model, OS version, app version) when something goes wrong, so we can fix it. This is not tied to your phone number or account identity by us. |
| Device attestation signal | Collected by Firebase App Check to help confirm requests are coming from a genuine copy of the app, as an anti-abuse measure. |
| Live audio/video during a call | Transmitted in real time between you and the other participant so the call can happen at all. See "Calls are not recorded" below. |
| A hashed (not plaintext) version of your phone number — only if your account is permanently suspended for repeat guideline violations | So the same number can't be used to delete the account and re-register to bypass the suspension. |
2. Calls are not recorded or stored
We do not record, save, or store your voice or video calls. Audio and video are relayed live, in real time, between you and the person you're matched with through our real-time communications provider (Agora — see below), and are not saved by Lungdei once the call ends. We only ever keep the call's type, length, and timestamp — never its content, and never who you spoke with.
3. Who we share information with
We don't sell your information, and we don't share it with advertisers. We use the following service providers to run the app; each processes data on our behalf under their own security and privacy commitments:
- Firebase / Google — authentication (phone sign-in), our database (Firestore), server-side functions, crash reporting (Crashlytics), and app-integrity checks (App Check).
- Agora — real-time voice/video transport for the live call itself. Agora carries the call's audio/video stream between participants; Lungdei does not configure or use Agora's cloud recording or storage features.
4. Age and eligibility
Lungdei is only for people 18 and older. Your date of birth is checked both in the app and by our servers before your account can be created or updated, so an account can't be created or kept with a birth date showing an age under 18.
5. Where sign-in is available
Account creation currently requires an Indian (+91) mobile number verified by SMS code. We don't currently support sign-in with other country codes.
6. How long we keep information
| Data | Retention |
|---|---|
| Profile (phone, date of birth, age, gender, community, filters, blocked-user list) | Until you delete your account. |
| Call history | Until you delete your account (or you can turn off saving new history at any time on the You tab). |
| Reports (filed by you or against you) | Retained after account deletion for safety, moderation, and audit purposes. |
| Records of who you called and when (kept internally on our servers, not shown to you as "who") | Kept for 90 days after the call ends, then automatically deleted — unless a report was filed about that call, in which case the record is kept alongside the report instead. |
| Crash and diagnostic data | Retained for as long as Firebase Crashlytics retains it under Google's own data retention policy. |
| Hashed phone number (only if your account is permanently suspended) | Retained after account deletion, so a suspended number can't simply re-register a new account to bypass the suspension. |
See Delete your account for exactly what is deleted when you delete your account, and what is retained.
7. Your rights and choices
- Access — you can see your phone number (masked), age, and community on the You tab, and your call history on the Activity tab.
- Correction — you can change your community at any time on the You tab. Gender can be corrected by contacting support@primeliva.com. Date of birth can't be changed after onboarding — it's what your age, and our 18+ check, are derived from — so contact support@primeliva.com if you believe there's a problem with it.
- Deletion — you can delete your account and associated data at any time. See how to delete your account.
- Export / a copy of your data — email support@primeliva.com and we'll get you a copy of the data described in section 1.
- Blocking — you can block anyone you're matched with, and manage your block list from You → Blocked people.
8. Children's privacy
Lungdei is not directed at, and must not be used by, anyone under 18. We enforce this with the date-of-birth check described above and do not knowingly collect data from anyone under 18.
9. Security
Your data is stored with Firebase and protected by access rules that restrict it to your own account. Connections between the app and our servers use encrypted connections. No system is perfectly secure, and we can't guarantee absolute security.
10. Changes to this policy
We may update this policy from time to time. If we make material changes, we'll update the effective date above.
