Frequently asked
questions

CyphrPost is a private social network for you and the people you choose. You can post photos, comment and chat, like on other social apps. The difference is that your posts, photos, comments and messages are encrypted on your phone before they’re sent. We can’t read them, and neither can anyone else outside your friends.

CyphrPost is free to join and has no ads. We don’t sell your data and there’s no advertiser paying for your attention. The app is supported by the people who use it, through Buy Me a Coffee.

Only your friends and the people you choose. There are no public posts on CyphrPost, we can’t see anything and neither can strangers.

Your feed shows your friends’ posts, newest first. There’s no algorithm choosing what you see, no ranking and no sponsored posts.

Use your email address, your Google account, or your Apple ID (Apple sign-in is on iPhone only). You need to be 18 or older. Email addresses with a plus sign in them (like name+extra@gmail.com) can’t be used to sign up with email.

Search for them by name or username, scan their CyphrPost QR code, or send them your invite link. If someone joins from your invite link, a friend request to you is sent automatically once they finish setting up. While your feed is still empty, the Home screen also suggests friends of your friends.

No. Your posts, photos, captions, comments, bio and chats (one-on-one and group) are encrypted on your phone before they leave it. The keys stay with you and your friends, not with us. Our encryption is provided by Seald, a French company owned by OVHcloud.

The few things we need to run your account: your email address, your name, your username and your profile photo. We also see when you joined, the time things were posted, like and comment counts, and who you’re friends with (so your posts reach the right people). If the app crashes, we get a basic crash report to help us fix it.

Your name, username and profile photo are how people find you, so anyone on CyphrPost can see them. Your bio is encrypted and only your friends can read it.

Yes. Photos carry hidden details, like where they were taken and what phone took them. CyphrPost strips these off on your phone before the photo is encrypted and uploaded. You’ll see “Removing metadata…” while this happens. If it can’t be removed, the photo isn’t uploaded.

On purpose. Notifications on your lock screen never show names or content. Inside the app, a notification tells you who did something (for example, that someone commented on your post), never what they said. Open the app to read it.

No. Only you can share a link to your own post. The link shows a plain CyphrPost image, never your photo or caption, and only your friends can open the post itself.

No. We can’t open your posts or messages, so there’s nothing for us to sell, scan or feed to an AI model.

It keeps your account in your hands. Your account can only be active on one device at a time, so nobody can quietly log in somewhere else while you’re still using it. If you try to log in on a second phone, you’ll see “Active session detected” and you choose what happens next.

This is how you prove your encrypted posts and chats belong to you. When you log in on a new phone, after reinstalling the app, or after clearing the app’s data, Seald by OVHcloud, our encryption partner, emails you a verification code. Enter it in the app to unlock your posts and chats on that device. If you log in again on the same phone you usually use, you won’t be asked for it. Look for an email from Seald by OVHcloud.

This is a different code from the one CyphrPost emails you when you first sign up. Never share either code with anyone.

Log in to CyphrPost on your new phone. When you see “Active session detected”, tap Log out of the other device. This logs you in on the new phone and signs the lost phone out at the same time. Then enter the Seald code from your email to unlock your posts and chats.

It also helps to lock or erase the lost phone using Find My (iPhone) or Find My Device (Android).

On the “Active session detected” screen, tap Can’t access your other device? Contact Us, or email admin@cyphrpost.com. A CyphrPost admin can end the session on your old device for you, so you can log in on your new one. To keep your account safe, we may email you first and ask a few questions to confirm it’s yours.

You’re signed out of this phone. Next time you log in, you’ll need to verify the device again to unlock and restore your chats.

Yes. Your account is tied to the hidden Apple email, not your real one. Always log in with Apple. If you sign up again with your real email address, you’ll get a second, separate account.

Go to Settings and choose Delete Account. Your account is deleted after 30 days. If you change your mind, log back in within those 30 days and your account comes back. After 30 days, everything in the account (posts, photos, comments, chats and profile details) is permanently deleted. This includes your one-on-one chats, so the people you chatted with lose those messages too. None of it can be recovered by you or by us.

Tap the menu on the profile, post or comment and choose Report. Pick a reason, such as spam, harassment, hate speech, a scam or a fake profile, and attach a screenshot of what you saw. Then send it.

Because we can’t see what was posted. Everything on CyphrPost is encrypted, including from our own team. Your screenshot is the only way an admin can see what happened. A screenshot is optional, but a report without one is much harder for us to act on.

Not directly. Chats are encrypted end to end, so they can’t be reported from inside the chat. Instead, report the person from their profile and attach a screenshot of the messages.

Our admin will review the report and your screenshot. Admins can’t see posts or comments, so they can’t remove a single post or comment. Instead, they act on the account that broke the rules:

• Warning: the admin emails the person directly.
• Suspension: the account is banned for good. It can’t be logged into again, and the same email can’t be used to create a new account.
• Deletion: the account and everything in it is permanently removed. The person could sign up again as a new user, starting from nothing.

They can no longer see your posts, and they can’t find you in search. Your one-on-one chat with them stays readable, but neither of you can send new messages. If you’re both in a group chat, you’ll both stay in it and can still see each other’s messages there. The app reminds you of this when you block someone.
