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 only an email and password, keep your contacts under aliases, and activate sending with Bitcoin after a seven-day free trial.
0.0025 BTC / year
Activation after one confirmation when the free trial ends.
Receiver-friendly
Paid access is required for sending. Receiving and decrypting can remain open.
Private sign-up
Email and password only. No names or extra profile data.
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
BTC-only activation
Accounts begin with a seven-day trial. When the trial ends, a payment of 0.0025 BTC per year is required, with one confirmation for activation.
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.
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.
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.
Pricing

- 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
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.
Payment is due after the seven-day free trial. After one blockchain confirmation,
the paid account is activated for the next yearly term.
The product direction includes documents, spreadsheets, CSVs, PDFs, slides,
images, and most standard client file types under the same encrypted relay model.
