PRIVATE MESSAGING, CLEARLY

Everything you expect from a messenger. Less personal information.

Vaultlix brings private conversations, media sharing and calls together without asking for your phone number, email address or contact list.

Message privately

Send encrypted texts, replies and voice notes in one-to-one or private group conversations.

Share moments

Share encrypted photos, videos, GIFs and files with the people you choose.

Call securely

Move from chat to protected voice or video calls inside the same conversation.

A Vaultlix number is an app-specific identity. It works only inside Vaultlix—it cannot receive regular calls, SMS messages or OTPs, and it is not a virtual SIM.

PRIVACY MADE SIMPLE

Your conversations stay between you.

Only you and the person you connect with can read your messages or hear your calls.

When you erase a conversation, it is designed to stay inaccessible.

FREQUENTLY ASKED QUESTIONS

The important questions, answered clearly.

What is Vaultlix?

Vaultlix is a private encrypted messenger for chats, photos, files, voice calls and video calls. Your app-specific Vaultlix number lets people connect without learning your personal phone number.

What identifies my account?

A permanent, system-generated Vaultlix number and the username you choose. The number is not a cellular number and cannot receive SMS or ordinary calls.

How do I connect with someone?

Exchange Vaultlix numbers, enter their exact number, and send a connection request. Once accepted, Vaultlix creates the encrypted conversation automatically.

Is Vaultlix end-to-end encrypted?

Yes. Strong encryption protects your messages, voice calls, and video calls. Only the people in the conversation can read or hear them—not Vaultlix.

Can people search for me?

No. Vaultlix does not search contacts or suggest people. Someone needs your exact Vaultlix number before they can send a connection request.

Can I create a private group?

Yes. Vaultlix supports private group conversations as well as one-to-one chats.

Ready to message privately?

Create your Vaultlix identity, connect by consent, then message, share and call.

Privacy Policy

Effective date: 16 September 2026 · vaultlix.com

The short version: We don't ask for your public identity, and we can't read your conversations. When a conversation is erased, its live contents and access are removed — see below for exactly what that covers.

What we collect

Vaultlix requires no email address, phone number, or real name. Accounts use a system-generated Vaultlix private number and your chosen username. Adding a profile image is optional.

What exists on our servers is:

The encrypted content of private and group messages, retained so it can be delivered to participants for the conversation's lifetime; see "How long things last" below
The display name each person chooses for their Vaultlix identity
An optional profile image, if you add one. It is shown to people who use your exact Private Number or connect with you, and is removed when you remove it or delete your account.
If notifications are enabled, a Web Push subscription (an endpoint address tied to your device, provided by Apple's or Google's push service) so a message or call can wake the app
Memory-hard authentication verifiers for identity sign-in — never the password itself
Standard server access logs generated by Railway (our hosting provider) which may include IP addresses and request timestamps
Anonymous, aggregate usage counts (for example, how many conversations are active) — never linked to a readable conversation, private number, or message
Your system-generated Private Number, chosen display name, optional profile image, encrypted key wrappers, active-session verifiers, and an opaque encrypted account bundle containing conversation credentials. We do not receive the password, recovery code, readable conversation list, access tokens, or private keys.

A conversation access token is created after a connection is accepted and kept on your device so the app can restore your conversations and route notifications correctly. It proves access to that conversation without being a real-world identity. Active encrypted state and access tokens are checkpointed to restricted persistent storage so the service can survive failures and backup restoration.

How messages work

All messages are end-to-end encrypted using AES-256-GCM with keys generated in your browser. The server never sees your message content — only encrypted ciphertext that it cannot read.

Private groups use a separate random group key. That key is encrypted individually through each member's existing private conversation. Vaultlix stores the group membership needed for delivery, encrypted group names, encrypted key wrappers, and encrypted messages, but cannot read the group name or messages. Removing a member rotates the group key before new messages can be sent.

Encrypted conversation ciphertext, participant access data, chosen display names, notification routing details and access tokens are written to restricted persistent storage. Encrypted image and file payloads are kept in private object storage; the conversation database retains only opaque storage references and delivery metadata. This lets conversations survive service failures and planned deployments. Infrastructure backups may retain an encrypted copy until the backup expires or is deleted; Vaultlix still cannot decrypt message or attachment ciphertext. Account records—including opaque encrypted account bundles and authentication verifiers—persist so a user can restore access after reinstalling.

How long things last

A conversation and its live message state are deleted immediately if either person uses "Close & erase." Established private-number connections remain available until someone closes them. Older encrypted infrastructure backups remain subject to the provider's configured retention period.

Disappearing-message timers, when enabled, delete an individual message from live storage as soon as its timer expires.

File attachments

Files are encrypted on your device before upload to private object storage and can only be decrypted by participants in that conversation. Access links are short-lived and require current conversation membership. Files follow the same conversation retention controls described above.

Voice and video calls

Call signaling is encrypted with the conversation's end-to-end encryption key. WebRTC then encrypts audio and video between participant devices using DTLS-SRTP. To prevent either participant from learning the other's IP address, Vaultlix routes call traffic through Cloudflare's TURN service. Cloudflare relays encrypted media packets and processes the connection metadata required to operate that relay, but cannot decrypt call audio or video. Vaultlix does not record or store call media.

Cookies and tracking

Vaultlix does not use cookies, analytics trackers, or advertising pixels, and does not use Google Analytics or an equivalent analytics service. Optional GIF search is provided by KLIPY as described below.

Third-party services

Vaultlix is hosted on Railway (railway.app). Railway may collect standard infrastructure logs including IP addresses. Please review Railway's privacy policy for details. We use Google Fonts for typography — fonts are loaded from Google's servers. Voice and video calls use Cloudflare's TURN service, which relays DTLS-SRTP-encrypted media packets and processes the connection metadata required to operate the relay but cannot decrypt call audio or video. Push notifications are delivered through Apple's and Google's respective push notification services, which see that a notification was sent to your device but not its content.

If you open the GIF picker, your device sends searches, language/region settings, and ordinary network information such as your IP address directly to KLIPY. When a GIF is displayed, the recipient's device loads it directly from KLIPY. The selected GIF reference is included inside the end-to-end encrypted Vaultlix message, but the GIF file itself is delivered by KLIPY and is not end-to-end encrypted by Vaultlix. Vaultlix does not send your private number to KLIPY or proxy, cache, or re-host KLIPY media.

If you expressly use Daily Look, the photo you select is sent to OpenAI to create the requested image. Vaultlix does not keep the selected source photo after that request. OpenAI may retain API inputs and outputs for abuse monitoring under its API data controls; API data is not used to train OpenAI models by default. The created image remains on your device unless you choose to use it as your Vaultlix profile image.

Content safety and reports

Vaultlix does not automatically classify or block private message text, photos or videos. Use Report and Block to stop unwanted contact and send selected evidence to our reviewer. Images submitted to Today’s Look are processed and moderated by the image-generation provider only when you choose to use that feature.

When you submit a report, we receive its category, your written details, the reporting and reported account identifiers, and the conversation reference. Up to five recent text messages are shared with our reviewer only if you explicitly select the message-sharing option. Reports are reviewed by the operator within 24 hours. Unresolved reports remain available until handled; resolved reports and review notes are removed 90 days after their last review update. Account-level block records remain while needed to enforce your block. A reviewer may close a reported conversation and suspend an account from new connections; restrictions can be reviewed on appeal. Contact privacy@vaultlix.com for follow-up or an appeal.

Profile photos and display names are linked to your Vaultlix account and shown to people who know your exact private number or connect with you. Daily Look requests are authenticated to that account to enforce usage limits. Photos, report details and voluntarily shared report messages are therefore linked to account identity; end-to-end encryption of ordinary messages does not make these account features anonymous.

Children's privacy

Vaultlix is not intended for use by anyone under the age of 18. We do not knowingly collect information from minors.

International users

Vaultlix is operated from India and this policy is governed by Indian law, as stated below.

What we can provide is limited to records that exist at that time, including encrypted conversation content, identity profile data and infrastructure logs. We cannot decrypt message content ourselves.

You can use Report and block in Conversation Safety, or contact legal@vaultlix.com. Report contents, access controls, retention and response commitments are described in Content safety and reports above.

Changes to this policy

We may update this policy from time to time. Updates will be reflected on this page with a revised effective date.

Frequently Asked Questions

vaultlix.com

What is Vaultlix?

A private messaging and calling app built around a system-generated Vaultlix Private Number. People connect by exact number and mutual consent, without uploading contacts or providing a phone number or email address.

Do I need an account or a phone number?

No. Vaultlix does not require a phone number, email or real name. It gives you a system-generated Private Number for sign-in, recovery and exact-number connections.

Is it actually anonymous?

Vaultlix uses a system-generated Private Number and an opaque encrypted account bundle; no phone number, email or real name is collected. The Private Number is not a cellular number and cannot receive SMS or ordinary calls.

Is it end-to-end encrypted?

Yes. Messages are end-to-end encrypted with keys held by the participants. WebRTC call audio and video is encrypted between participant devices with DTLS-SRTP. Cloudflare TURN relays encrypted packets to hide participants' IP addresses from each other, but cannot decrypt call media. Conversation credentials are wrapped inside a separate client-encrypted account bundle before sync; Vaultlix cannot decrypt that bundle.

What happens when I close a conversation?

It's deleted immediately, for both people, along with everything inside it. Not archived, not hidden — gone.

How do private connections work?

Enter an exact Vaultlix Private Number and send a request. The other person must accept before a one-to-one conversation is created. Either person can later close and erase the conversation.

Can I create a private group?

Yes. Vaultlix supports private group conversations as well as one-to-one chats.
