Install CRIV as a private PWA for faster text and file decryption on any device.

Private text and file relay

Encrypt what matters. Verify every exchange.

CRIV is a privacy-first relay for encrypted text, documents, spreadsheets, presentations, images, PDFs, and more. Register with email, choose annual BTC or PAYG, keep contacts under aliases, and start with a seven-day free trial.

Annual: 0.0025 BTC / year PAYG starts at $10.00 top-up. Credits remain valid for one year.
Receiver-friendly Paid access is required for sending. Receiving and decrypting can remain open. Calls do not stay open to free receiver-only access.
Registered-user calls Voice, video, and secure call mail only work between logged-in registered CRIV users who saved each other.
Manual-decrypt live chat Live chat is only for saved registered CRIV contacts, uses manual decrypt by default, and is purged from the server when the last participant leaves.
Private sign-up Email-based sign-in with OTP, plus annual or PAYG billing choice. No names or extra profile data.
Capture deterrence Sensitive CRIV pages white out when the app loses active focus. Browsers and PWAs still cannot guarantee screenshot or screen-recording blocking while the page stays active.
What CRIV covers

Built for private clients and low-friction delivery

Tx

Encrypted text relay

Compose, encrypt, and route messages to saved contacts. Receivers can open the ciphertext in the CRIV web app or PWA and decrypt it there.

Fx

File encryption for nearly any format

Support is planned for DOC, XLS, CSV, PDF, PPT, images, and most other common business files using the same private relay model.

Ad

Alias-based address book

Store an email address, WhatsApp number, encryption key, and a contact alias. No legal names are required anywhere in the client experience.

B1

Annual or PAYG billing

Accounts begin with a seven-day trial. Choose annual (0.0025 BTC / year) or PAYG wallet billing with $10.00 minimum top-up.

Rx

Receiver access without a paid seat

Sending requires an active paid account. Receiving and decrypting can remain available through the website or PWA without forcing every recipient into a subscription. Voice, video, and call mail are separate and require registered logged-in users on both sides.

Vc

Voice, video, and secure call mail

Saved CRIV contacts who are both registered and logged in can place voice or video calls and leave secure voice or video mail when a contact is unavailable.

Lc

Encrypted live chat

Saved registered contacts can open live chat sessions where each incoming message remains encrypted until the recipient clicks Decrypt.

Dd

Delete all files after decryption

Once a recipient decrypts a file, both the encrypted and decrypted server-side files should be deleted. No files are retained on the server after decryption completes.

Nt

Email alerts for waiting activity

When secure text, file, or call activity reaches your CRIV account, an email alert can tell you something is waiting so you can sign in and open Notifications.

How it works

One contact book. Two delivery paths. Minimal identity.

1

Create a private account

Register with only email and password. No personal profile fields are required.

2

Add a contact alias

Save an alias, an email address, an optional WhatsApp number, and the contact key.

3

Encrypt text or files

Send by email or WhatsApp when those channels exist in the address book. Sending is paid-only.

4

Decrypt from the web or PWA

Receivers open the encrypted payload in CRIV and decrypt it there, even without a paid account.

5

Use live chat only with saved registered contacts

When both sides are registered, logged in, and saved in each other's Contacts, CRIV can open live chat with manual decrypt per message and optional local export before leaving.

Pricing

Privacy baseline

Private by policy and by product shape

CRIV is set up as an installable client for private exchange, not a social platform. The registration flow requests only the minimum credentials required to manage a private account.

CRIV intentionally avoids separate iOS App Store and Google Play apps. Native store distribution can add more account linkage, device-level identifiers, review dependencies, and third-party policy exposure than this product direction wants. The private PWA keeps installation simple while reducing that extra surface.

  • No name field in registration
  • Email and password only
  • Contact aliases can be fictional
  • Receiver workflows can remain account-light
  • All server-side file copies should be deleted after decryption
  • No App Store or Play Store account dependency
  • Lower device-tracking and store-metadata exposure
  • Direct web and PWA updates without app review delays
Frequently asked

Common questions before clients start

Full FAQ
CRIV is positioned so sending requires a paid account, while receiving and decrypting can be available through the website or installed PWA without paid enrollment.
No. Voice calls, video calls, and secure call mail are only available to logged-in registered CRIV users. Free receiver-only access is for decrypting delivered text or files, not for calls.
Only logged-in registered CRIV users who already saved each other in Contacts can use live chat. Free receiver-only access does not include live chat.
CRIV live chat is designed to purge server-side chat data when the last participant leaves the page. If a client wants to keep a copy, they should use Save Chat to Device before leaving.
Annual payment is due for annual-plan senders. PAYG senders top up credits and are billed per use.
The product direction includes documents, spreadsheets, CSVs, PDFs, slides, images, and most standard client file types under the same encrypted relay model.
CRIV is designed to reduce unnecessary identity and device exposure. A private PWA avoids extra App Store and Play Store account linkage, reduces dependence on store review cycles and policy changes, lowers pressure to add mobile SDK tracking layers, and still gives clients an installable experience on phones, tablets, and desktops.
