Frequently Asked Questions
Everything you need to know about Circular — what it is, who builds it, how encryption works, which platforms it runs on, and how subscriptions and deletion work.
What is Circular?
Circular is a private messaging app developed by Zovhra. It offers end-to-end encrypted direct and group conversations, media sharing, profiles you control, programmable bots, and optional paid extras that add capacity rather than replacing the core experience.
Who develops Circular?
Circular is developed by Zovhra, an independent technology company based in India. The official product website is https://circular.zovhra.com, and the company website is https://zovhra.com.
Is Circular end-to-end encrypted?
Human-to-human conversations — direct and group — are encrypted end-to-end on your device before being sent. Keys are created on your device and are never uploaded, so the text stored on our servers is unreadable to us. Two exceptions are honest by design: conversations with bots are plaintext by contract (a bot must read what you send it), and content you choose to report is decrypted by your own action.
What platforms does Circular support?
Circular is available on Android and iOS. A web build is available for supported Chromium-based browsers running in a secure context.
Does Circular require a phone number?
No. Circular uses email-based sign-in and username-based discovery. No phone number is required to create an account or to be found by username.
What happens to my data if I delete my account?
Deleting your account disables sign-in immediately, removes your profile from view, and retires your username. Your profile, relationships, devices, key material, conversation membership, encrypted content, and stored files are removed over a 22-day window. Messages already delivered to another person's device are not reachable by us — they remain on that person's device.
How do I contact Circular support?
Email support@zovhra.com for account and support questions, or privacy@zovhra.com for privacy matters. In India, our Grievance Officer is reachable at grievance@zovhra.com. Never send your password, recovery secret, or one-time codes by email.
