Frequently Asked Questions

It’s free, with no ads. There are no in-app purchases.

Because it doesn’t need it. You sign in with a name, any name you like, and you talk to the people you invite. Your number isn’t anywhere in TruchiChat, so no one can find you by it.

There’s no search, and your contacts aren’t read. You create an invitation in Settings and the other person scans its QR code from their TruchiChat, or you send them the code some other way. Each invitation works once and expires after 24 hours.

Yes. An iPhone and an Android phone can chat and call each other, with the same features except where each system requires something different: for example, the app lock uses Face ID on iPhone and your fingerprint or face on Android.

It’s in closed testing, and it will be available to everyone very soon. If you have GrapheneOS or prefer to use Android without Google services, you can already download the Android without Google version.

No. TruchiChat is phone only: iPhone with iOS 17 or later, and Android 12 or later.

No: one phone per account. The keys that open your messages are only on that phone, which is why your messages aren’t in any cloud.

You create a new account on the new phone and invite your contacts again. Chats don’t carry over: your history and keys never leave the old phone, not to iCloud, not to Google, not to a copy of ours. If you want to keep a photo or a file, save it to your phone first.

Your conversations are lost. On Android, your account is lost too and you’ll have to create a new one. On iPhone, when you reinstall it, you get your account back but not your chats.

In the app, Settings › Delete Account: it’s deleted on our server and on your phone, and your contacts see in the chat that the account has been deleted. Without the app, write to us. All the details.

No, on purpose: chats are between two people, for privacy. A group is a stored list of who talks to whom, and that’s exactly what we don’t want to have.

No. Your history is only on your phone. There’s no copy that can be lost, requested or stolen, but there’s also none that can give you your chats back.

No. Searching would require storing an unencrypted index of your history, and we don’t do that.

A video, up to 100 MB once compressed. A photo, a file or a view once video, up to 50 MB.

No. They’re encrypted on your phone, and only your contact’s phone has the key to open them. Our server passes them along sealed and deletes anything undelivered after 24 hours.

The name you choose, your profile photo if you set one, which account writes to which and when, and the size of what’s sent. Nothing of what you say. We explain it in full.

No. TruchiChat’s code is private. Your security doesn’t depend on that: your messages are encrypted on your phone with public, well-studied algorithms (X25519, ChaCha20-Poly1305 and Ed25519), the key never leaves it and the server only sees sealed envelopes. And you can check your contact with their safety number.

No outside party has audited TruchiChat.

Compare the safety number by scanning each other’s QR code, ideally in person. If your contact’s key changes, the app warns you. Step by step.

Who’s writing and “New message.” Never the text.

Block or report them from their contact info. When you block them, the chat is deleted on both phones. A report says who they are, the reason, whatever you write and which chat it’s about; it never sends what’s in the chat.

A small, independent team. No ads and no selling data: the people who make it pay for it.
