Cyphr Review 2026: Golden Frog Messaging App Retired
Cyphr is no longer an active encrypted messaging service. Golden Frog, the company associated with VyprVPN, has retired the app and no longer presents it as a supported product. You should not download old Cyphr installation files or rely on the security claims in reviews written while the service was still operating.
This updated Cyphr review explains what the app was, how Golden Frog said its encryption worked, why the original review is now obsolete and whether VyprVPN replaces any of its messaging features.

Cyphr status at a glance
- Developer: Golden Frog
- Original purpose: Free encrypted messaging for iOS and Android
- Current status: Retired and no longer recommended
- Can new users rely on it? No
- Does VyprVPN replace it? No; a VPN and an encrypted messenger protect different parts of a connection
Is Cyphr still available?
No. Golden Frog's current Cyphr status page says the service is retiring and directs visitors towards VyprVPN instead. It no longer provides the active iOS and Android download links promoted when Cyphr launched.
That means the original version of this article was materially out of date. Statements describing Cyphr as new, free and suitable for sending sensitive information should not remain on a current security website. An unsupported communications app can stop working, lose compatibility with modern operating systems or retain unpatched weaknesses.
You may find unrelated services using Cyphr, Cyph or Ciphr in their names. They are not automatically connected to Golden Frog's retired Cyphr app. Check the developer and official domain before installing anything.
What was the Golden Frog Cyphr app?
Cyphr was a free messaging application released by Golden Frog, the company that created VyprVPN. Its original apps allowed Cyphr users to exchange text, photos and attachments on Android and iOS.
In its original Cyphr announcement, Golden Frog described the service as a zero-knowledge encrypted messenger. The company said messages were encrypted on the sender's device and could be decrypted only by the intended recipient. Encrypted messages passed through Golden Frog-operated servers in Switzerland.
Cyphr was intended to offer a more private alternative to ordinary SMS and messaging platforms whose data-handling models concerned privacy-conscious users. It also benefited from Golden Frog's existing account system and experience operating VyprVPN.
Those historical claims explain why Cyphr received positive coverage at the time. They do not make the retired software safe or suitable today.
How did Cyphr encryption work?
Golden Frog said Cyphr generated public and private encryption keys for each user. A sender used the recipient's public key when encrypting a message, while the corresponding private key remained on the recipient's device and was required to decrypt it.
The service also used symmetric encryption for message content and transport encryption while data moved between devices and its servers. Golden Frog said its servers temporarily stored the encrypted message, the time it arrived and the information needed to deliver it. The server copy was supposed to be deleted after delivery.
These descriptions came from Golden Frog's own documentation. The old article incorrectly turned provider claims into absolute conclusions such as “no risk” and “only the people in the chat can read the messages”. Security claims should be assessed against current code, documented protocols, independent audits, update history and the complete threat model. That assessment is no longer practical for a retired service.
Why the old Cyphr rating is no longer valid
The previous article awarded Cyphr a score of 8.5 and called it reliable and safe. That rating must be removed for four reasons:
- The service has retired: availability is a basic requirement for any current recommendation.
- The original review relied heavily on provider statements: it did not document a current independent technical assessment.
- Its device information was obsolete: desktop and web versions were described as coming soon rather than available.
- “Military-grade 256-bit encryption” was not a sufficient evaluation: an algorithm name or key length does not establish that the complete app, key management and server implementation are secure.
The review score and the old summary box should therefore not be retained as historical ratings. A reader arriving today needs the retirement status first.
Should you download Cyphr from an unofficial website?
No. Avoid archived APK files, unofficial app stores and download pages claiming to provide the old Cyphr client. Even if a file is an authentic old release, it may contain known vulnerabilities, depend on retired servers or be incompatible with current Android and iOS security requirements.
A lookalike file could also be modified to include malware or steal account details. An unsupported security app is particularly risky because users install it specifically to handle private communications.
Did VyprVPN replace Cyphr?
No. Golden Frog now directs Cyphr visitors towards VyprVPN, but the two products serve different purposes.
- Cyphr: encrypted messages between people using the same messaging service.
- VyprVPN: encrypts network traffic between your device and a VPN server and changes the public IP address seen by websites.
A VPN can reduce what an internet provider or untrusted Wi-Fi network can directly observe, but it does not automatically add end-to-end encryption to an ordinary message. The messaging service can still process whatever account and message data its design permits.
VyprVPN remains an active product and can be assessed separately. Read our current VyprVPN review for its supported apps, protocols, privacy policy and limitations.
Cyphr review verdict
Cyphr may have been an interesting encrypted messenger when Golden Frog launched it, but it is not a service anyone should begin using in 2026. The official retirement notice makes availability, pricing and feature comparisons irrelevant.
This page remains online to correct the historical review and help readers distinguish Golden Frog's discontinued app from unrelated products with similar names. The former 8.5 score, download recommendation and claims of guaranteed safety have been removed.
Frequently asked questions
What happened to the Cyphr messaging app?
Golden Frog retired Cyphr. Its current Cyphr page no longer promotes active app downloads and instead directs visitors towards VyprVPN.
Can I still create a Cyphr account?
You should treat the Golden Frog Cyphr service as discontinued and unsupported. Do not rely on old instructions, archived installation files or third-party websites offering accounts or downloads.
Is Cyphr the same as VyprVPN?
No. Cyphr was an encrypted messaging app. VyprVPN is a virtual private network that encrypts traffic between a device and a VPN server. A VPN does not replace the end-to-end encryption provided by a properly designed messaging service.
Is Golden Frog's Cyphr the same as Ciphr or other Cyphr apps?
Not necessarily. Several unrelated products use similar spellings. Golden Frog's retired product was the Cyphr messaging app associated with VyprVPN. Always verify the developer and official website.
