Delete your DuoVault account
DuoVault by XTI Co., Ltd. (주식회사 엑스티아이) · Last updated October 23, 2026
How to delete your DuoVault couple vault account and the data on our servers. You can delete it right in the app, or request it by email even if you've removed the app or can't open it. My Vault lives only on your device and was never on our servers.
1. Delete in the app
Android
- Open DuoVault and unlock it with your vault passcode.
- Go to Settings → Account → Delete Account. It appears only while you're signed in. If you're signed out, sign in first from the Couple tab with the Google or Apple account you used.
- Review what is deleted and what stays, then tap Delete Account.
- Sign in with Google or Apple once more to confirm it's you, and the deletion runs right away.
iPhone (iOS)
The iPhone app gets the same menu (Settings → Account → Delete Account) in its next update. Until then, please use Request by email below.
2. Request by email (no app needed)
- Email [email protected] with the subject “DuoVault account deletion request”.
- Send it from the email address you signed in to DuoVault with, and say whether you signed in with Google or Apple.
- If you used Apple's ‘Hide My Email’, your account address is the relay address Apple created (…@privaterelay.appleid.com). Find it on iPhone under Settings → [your name] → Sign-In & Security → Sign in with Apple → DuoVault. If you write from your usual address, we'll send a confirmation email to that relay address.
- Once we've confirmed it's you, we delete exactly what the in-app deletion deletes and reply with the result.
We reply within two business days (weekdays 09:00–18:00 KST) and delete without delay once your identity is confirmed. To make sure no one deletes someone else's account, we don't act on requests we can't confirm through the sign-in email.
3. What is deleted and what stays
| Data | When you delete your account |
|---|---|
| Sign-in account | Deleted right away — user ID, email, display name, linked sign-in methods (Firebase Authentication) |
| Profile and user data | Deleted right away — public key, display name, the passcode-wrapped key copy, breakup-terms consent record, diagnostics and usage-step records |
| A couple vault you created | Deleted right away — photos and videos (ciphertext), thumbnails, activity log, invite codes. What your partner uploaded is deleted too, and they can no longer open it. |
| A couple vault your partner created | You leave it. Photos and videos you uploaded and your activity are deleted right away; the vault and what your partner uploaded stay with them. |
| Subscription records | Deleted right away — subscription status, the link between payments and your account (transaction identifiers), benefit grants and promo-code use |
| My Vault | Not affected — it lives only on your device and was never on our servers. To erase it from the device, use Settings → Reset App (Delete Everything) or delete the app. |
| Copies on your partner's device | Copies your partner saved on their own device (photo library, their My Vault) can't be deleted by us. |
| Payment history | Kept by Google Play and the App Store under their own policies. We never receive card numbers or other payment details. |
| Ad attribution and subscription-change historyFrom November 22, 2026 · iPhone | Stored under a random install identifier, not your account, so it isn't linked to it. Deleted automatically 1 year and 2 years after collection, respectively. |
| Crash records | Not linked to your account; deleted 90 days after collection. |
| Server operation logs | Execution logs of our server functions may contain your account ID and are deleted automatically within 30 days. |
Deleting your account can't be undone. Signing in again with the same Google or Apple account starts a new account.
4. Cancel your subscription separately
Deleting your account does not cancel your subscription. Google Play and the App Store handle billing, so you may keep being charged unless you cancel. Please cancel before deleting your account.
- Google Play: Play Store → profile → Payments & subscriptions → Subscriptions → DuoVault → Cancel subscription (play.google.com/store/account/subscriptions)
- App Store: iPhone Settings → [your name] → Subscriptions → DuoVault → Cancel Subscription
Refunds follow each store's process (Subscription and Billing Policy).
