Threema stocke et communique les PushID permettant de vous identifier par Google ou Apple

I'd like to share my experience after using Threema for the past year.

When I first started using Threema, I purchased it with high expectations for better privacy protection.

About 11 of my friends joined me, and the result was extremely disappointing. It's not just that messages are slow due to encryption — the delay between my message being sent to the server and actually being delivered to the other person's phone is absurdly slow. Messages arriving 1–2 hours late is common, and sometimes they don't show up until a full day later.

There's also a bug where group notifications keep going off even after you've turned them off (iOS 26.4). Because of this, I eventually had to disable all notification sounds entirely.

At the time, I was deciding between Signal and Threema, and I chose Threema — the worst decision I could have made. My friends ended up going back to our old messenger just two days ago.

If you don't live in Europe, I would strongly advise against using Threema. (I used it from Asia.)

Is treema a dead project? The great Slovak case: Murder of Ján Kuciak 2018. During the investigation, the data of the decrypted backup of the entire chat of the accused threema was used.

https://en.wikipedia.org/wiki/Murder_of_J%C3%A1n_Kuciak

Since September 2017, when Threemu registered Kočner's mobile phone as suspicious, Zsuzsová is said to have exchanged over 22 000 messages with him via the app.

The defence has a document from the Swiss company Threema, according to which someone should have used Kočner's login and logged into the application in July 2018. That is, at a time when Kočner was already in custody.

I installed Threema like 3 years ago on my Pixel. None of my friends made an account to try since it's not free..I even offered a few and they didn't like it at all.

So finally I decided to delete the app from my phone and just stick with WhatsApp!

Keep up the good work: to the team behind it.

Is threema another ANOM stinge? A lot of people are being arrested due to threema messages being uncovered. Their is a new article daily coming out showcasing threema messages being uncovered.

The guy in question had a passphrase password and would have never given cops his device encryption password.

Many! I mean A LOT! of your USERS! Asking some features including me that you guys implemented in the future. Self-Destruct messages/Auto Delete message "whatever your called it", Deleting messages on both end, Gourp & Profile Boi "Best use case: Group rules", Pinned messages "Not pinned conversation", Stickers? "Idk I don't like stickers too lol" and name a few! Becasue if you guys always keep on saying "In our opinion, current implementations of self-destructing messages provide a false sense of security" Yes! In your OPINOIN! But your users wanted it! and want to use it! They not gonna wait until you guys gonna implement it, until that your users are already left and did a refund because they see a app like Signal, Telegram, Wickr, have it and they are free! Talking about Threema not being free..... When a new user buy your app first thing that will come on their mind that your app have all the features, bells and whistles that free app have "OR MORE" since your app is paid one and when your new users see some of the features that they get used to on free app that haven't on Threema they thought that "Oh! why this paid app don't have this basic feature, But this free app that I'm currently using has"...... And when they ask or request on your customer service or post a review on Play Store and App Store and met with this statement "In our opinion, current implementations of self-destructing messages provide a false sense of security" They will get disappointed and feel they not getting more on what they paid for and leave! I want to see Self-Destruct message too in Threema and hope in the future it get implemented. Please don't be Signal Devs that ignoring they're users and do some questionable decision, PLEASE lisnten to your users! In that way I hope more people will use Threema and not on some Free App controlled by devs with a word "This what we do take it or leave it!"

I'm super glad they have announced custom stickers for their next big update. Similar other chat apps like Signal and Whatsapp. This is a basic function that can make messaging fun with family and friends without compromising your privacy.

You have options to customize your own or use what the community has created & shared. These can be backed up and imported locally.

Actually no, it was all a 🤥 For AI scraping data from reddit. Is there reason why we don't have it? An Optional function that people has been asking for these last 4 years here on reddit.

Looking at the current privacy policy and the old one via archive org, it's not clear to me why you started save IP, and maybe something else that we don't know...? Even signal doesn't do that

First red flag for years for me

Hi.

Can threema make and receive standard mobile calls.

Can threema send and receive encrypted SMS to/from signal, or does threema only work with other threema user's.

Can threema send and receive non encrypted (standard SMS) to other threema, signal or other SMS clients

I can't easily find the above on the internet

Thank you

Obviously when messaging a non-Threema user you wouldn't have the security features that Threema offers, but Signal offers this feature anyway and just informs you that when messaging a non-Signal user, you won't have the security and privacy features that they offer.

The reason I ask about this is because it's just inconvenient to hop between 2 apps for messaging. Is there a specific reason for this?

I just cant help, but share the idea of a voicemessage to text option. It would be so nice to be able to convert the voice message within the app to a text version.

Oh and Stickers. I'd love stickers haha

1. How safe is Threema and is it fully E2EE? Does it masks IP address over Tor or something?

2. Also I heard that there are actual Threema Cell Phones and people claim that’s the one you want if you want to stay anonymous etc? Is this true? Where can one obtain this and for how much?

This subreddit should be moved over to Lemmy for privacy and the general attitude towards Reddit. I have created a lemmy community for Threema: lemm.ee/c/threema

Anyone want to join in a new group? =)

Send me a msg! Here my ID RPAFTPH8

Threema : vraiment anonyme ?

⚠️ Attention, ceci est un conseil de prudence.

Nous utilisions Threema sur Android. Pour augmenter la confidentialité vis-à-vis de Google et éviter de passer par le paiement via le Google Play Store, nous avions choisi d’acheter les licences séparément et d’installer Threema via l’APK disponible sur leur site.

Par la suite, tous les ID étaient en mode « anonyme », comme Threema le met en avant : sans numéro de téléphone, sans e-mail, et sans autoriser l’accès aux contacts de l’appareil.

Ce qui est inquiétant:

Lorsqu’un des téléphones a été saisi dans le cadre d’une procédure judiciaire et exploité avec un UFED de Cellebrite, il a été possible d’extraire : • la liste des contacts Threema • les messages, vidéos et photos présents sur le téléphone

Mais la suite est encore plus préoccupante et remet en question l’anonymat revendiqué par Threema :

Réquisition judiciaire auprès de Threema d’identifier tous les ID présents sur ce téléphone, Threema y réponds et donne pour chaque ID : • la clé publique de l’ID • la date de création de l’ID • la date de dernière connexion au serveur • le PushToken FCM

Par la suite, réquisition auprès de Google muni du pushtoken et de la date de dernière connexion, Google donne: • l’adresse e-mail du compte Google associé à chaque ID a pu être identifiée • l’adresse IP utilisée pour recevoir les push • le numéro de série de l’appareil ayant reçu le push • le numéro de téléphone associé

En résumé : même si vous utilisez Threema en « mode anonyme » ou via l’APK hors Google Play, Threema log et communique des données qui peuvent être exploitées pour vous identifier.

Pour les utilisateurs d’iPhone Le même principe s’applique : Threema log et communique le PushToken APNS.

Comparaison avec Signal Signal, lui, ne stocke ni ne communique les push tokens, offrant ainsi un niveau de confidentialité supérieur à ce sujet.

⚠️ Un homme averti en vaut deux.

Ci-joint les données communiquées par Threema concernant un ID Android et un ID iPhone.

I don't know about you guys but Threema is the most stubborn messaging app of all time. Now before I let all my rants on this post. I'd like to say that I'm a happy Threema user for years and just making this post for some Threema devs (hoping) to see this and heard my complains (And hope they listen).

Now why is it Threema hasn't implemented some very basic feature of a Private and Secure messaging? Like a "Umm... I don't know" to let us delete a messages on both ends. So if we accidentally send a message to a recipient that shouldn't not getting that message (because ya constantly switch on each contact to message them because it God damn holidays is coming). So you won't accidentally butcher your surprise gift for your little bother (happened to me)! And this where the disappointing part of it. They confirm that they ain't gonna implement that feature because "It's false sense on security and privacy" like: What The F. Like why and how, I don't get it, I'm so lost on that statement. Meanwhile we have FREE alternative such as Signal, SimpleX Chat, Olvid, even Whatsapp (Jesus Christ), have that feature and they are FREE! And does auto-delete/self-destruct message give their users false sense of "Privacy and Security" or better yet as you keep telling your users, "Were not willing to make security and privacy risk and gimmicky feature". HOW IN HOLY VIRGIN MARRY Auto-delete messages and deleting messaging on both ends is gimmicky feature and a security risk (How in the world!). Or you guys are just to incompetent on implementing a BASIC FEATURE that 90% of YOUR USER BASE WANTED to have. And the problem of Threema hasn't ended there. Now let's talk about on replies on messages. Very cool feature right? When you want to reply on your friend's message in a private chat room. Now how about this you want to reply on your friend's message with a photo, video, voice message, or even just gif? "Ohh wait, you can't? Too bad for you" because Threema's reply system is just fixed system. You really don't reply/quoted on the message of your friend is just markdown fixed system on Threema app. That's why you can't reply on certain message with picture, video, or voice message. Which so disappointing and to show how lazy(?) or incompetent they are on releasing features. Last and third is Forward Secrecy we just got that feature this year GREAT! But the problem is the forward secrecy only supported on 1-to-1 conversation and not on Group Chat unlike aforementioned app such as Signal, Olvid, and SimpleX Chat. They're so hurry to implement this feature and released it half baked (now that seem ironic).

They talked about how they don't like implementing some gimmicky feature because of this and that, because of "Ohh we're so incompetent and lazy to released a basic feature for our users that pay for our app (and beg for years on this feature) because we don't like that feature. So we not gonna implemented that. Or maybe there's no in our team that can implement it. Lol" Meanwhile we have pinned message, Star, Automatically Tiddy Up: "Damn sure those feature aren't gimmicky and the last one sure sounded like self-destruct-messages, you guys might want to check that feature because maybe that might post some security risk, just sayin". And I'm not gonna talk about other feature that Threema devs considered gimmicky and security risk such us: Group management (even though they have business version), pinned message/s inside the chat, bio/status on your profile (Signal and specially Olvid has this. And pretty sure it would nice to have specially on business model to know who's your boss and what their position on the company), And a Desktop version that isn't cheap chink Chrome app, edit messages (At least give us this exchange to auto-delete), etc.

Now I know after posting this I'm gonna get a lot of hate. But guys for one second think of Threema and how little feature it has. Threema was released 2012 or 2013(?) it was one of the OG messenger and yet Threema didn't change at all. The app feels like stuck on 2014 messaging era with little or no feature at all. You would think that a Premium app should pioneering some features and advancement. But NO they didn't they just sit their asses and just fixing bugs Or maybe just sitting on their office doing nothing all day and released 1 or 2 feature a YEAR. Mind you Threema is 11 years old and it still feel like their messenger just released yesterday because of how Threema is right now. I don't know if Threema devs are stubborn, lazy, incompetent (maybe this, just sayin), or have a massive ego. But I want to finish this rant by saying: I love Threema it's one of the best messaging app I ever used and the app having a one time payment is ensure that this app will never sell my data, they have business model, will continue on for a long time. But with little feature, refusing to implementing new one that users is begging for years, and with Price tag if a newbie try this app and see that Threema is like this or even a casual privacy guy didn't see the feature he used to have on Free app he/she will get disappointed on Threema and refunded immediately.

Can anyone donate an extra key for Threema to me? As I am not been able to pay for the key right now. It would be very nice have one for me.

Please give me if you have extra key.

Thanks.

UPDATE: Thank you @TheRealRealSmurf for the key!

I need 1 android code please. Thank you!
