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.
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 or pay as you go, keep contacts under aliases, and start with a seven-day free trial.
Annual: $49.95 per 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
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 ($49.95 per year) or pay-as-you-go billing with a $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.

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 uses an Android app for Google Play billing while keeping the website available for private browser access and receiver workflows.
- 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 advertising SDKs or third-party analytics in the Android client
- Google Play is used only for Android distribution and billing
- The same encrypted CRIV account works in Android and on the web
Frequently asked
Common questions before clients start
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.
