I would say this is the normal behavior and without this apps wouldn’t work properly or connect in background, ex. to receive messages in chat apps and display a notification ex. when the system wakes them up via push notifications

I already explained in my previous message how it is different from Signal, time to read buddy, bye

Meanwhile me not giving a F about this news because I use CalyxOS and the feature to auto-restart the phone on inactivity with fine customizable time and not a fixed 3 days exist since a long time already there

The purpose is already said in the title: private chats for the family

How you don’t understand the use case of chatting with the family?

As many other chat apps out there, if you meant the “why this one and not X?” Well there are other acceptable options out there, the advantage of this one compared to WhatsApp, Telegram and co. Is that it doesn’t depend on phone numbers or any private data, getting started with the app is painless and smooth, no SMS verification no captcha solving or complex registration, just set your name and start chatting. It is decentralized and anonymous, while having a nice polished UI easy to use on the level of WhatsApp and Telegram, unlike most other alternatives out there

One special feature is the ability to use in-chat mini-apps that are completely “p2p e2ee” between chat members without depending on any server hosting it and working offline first, among such apps: collaborative editor pads, checklists/to-do lists, shopping lists, split bills with friends, chess and other mini-games etc

It is also possible to run GUI desktops in Termux since ages, for example take a look at:

AnLinux (Run Linux On Android Without Root Access) https://f-droid.org/packages/exa.lnx.a/

It was also possible to run a “full Debian” using PRoot etc

Threema is paid (registration tied to payment is already bad for privacy, most people will not register with some crypto-coin etc) and centralized, any centralized service is vulnerable to enshitification, none of them start evil, also it is easier to block by authoritarian governments and can’t be used in a sovereign/independent way (ex. own independent server in a local community)

Session: it has been a long time since I last used Session, at the time my impression was that it was a bit hacky and it was draining my battery and using a lot of mobile data, more importantly Session doesn’t seem to have multi-account support, also doesn’t seem to support using your own independent server “off-the-grid”. Session groups have a limit of only 100 members while in ArcaneChat groups can have 1000 members for now (or even more depending on the server you use, ex. your own)

none of them have in-chat collaborative/interactive apps (ex. collaborative editor, calendar, shopping lists, split bills, polls, etc.) and games that can be used even while offline

How on earth do you think the various Matrix clients are “this is for nerds” like and buggy? How do you come to this statement?

if you don’t even see the problem, I am not even sure it is worth to try to talk about it… ex. a private 1:1 chat in Matrix is a “room” the whole experience of starting a private chat with your mom is a series of “foo invited bar to room”, “bar joined the room”, etc. besides easy to end up in a state where not even you can read your own messages the famous “unable to decrypt”

Signal can be based on Useraccounts without phone numbers as well.

Signal depends on phone numbers, if you are talking about setting a nick-name (which Telegram supports since ages) that doesn’t mean anything a phone number is still required, just as in Telegram, and it is not an argument against my point that talked about the need for a SIM card.

And the registration process tbh is a pro and non a con

it is a con, period.

if you don’t provide a secured process you will be run over by bots at some time.

bots are supported and welcome, just as on Telegram, bots can’t spam people because, unlike on Signal with the phone numbers problem, in ArcaneChat people can’t just write to you randomly, they need your contact’s invitation link. Also in worse case, migrating your address is possible and cheap, you can have many accounts as you want and also create accounts temporarily to interact “in the wild”

Is that feature audited?

yes, ArcaneChat is a Delta Chat client, and the Delta Chat app and core has received several audits (six over the past of years so far), any Delta Chat client using the Delta Chat core benefits from the security audits, you can read about it here: https://chaos.social/@delta/113963707915543266 unlike many of the mentioned clients that don’t have any known security audit at all?

BTW: Furthmore your website does not confirm with German legal requirements and makes you an easy target for bad faith lawyers,btw.

could you tell me what is wrong with it? my address is show in the terms & privacy policy / GDPR, but I admittedly am not well informed in German law topics, so if you could point me in the right direction I would be really grateful

post-data: please don’t read my reply as a aggressive discussion, I am just providing arguments, not trying to fight unknown people in the Internet, and I appreciate you took your time to reply, have a nice day!

I wrote to the admin asking for including the 64bit version, let’s see

Sure thing! ArcaneChat is decentralized: https://github.com/ArcaneChat/server

The app supports 64bit!! It seems you downloaded the apk for 32bit platform, if you are using IzzyOnDroid repo, that only provides the 32bit apk, switch to the official F-Droid repo, install from Google Play or download the apk for 64bit manually from the github releases page

I bet it is using more resources than my +1400 people server 😅 but yeah for 10 people it is probably OK with matrix as long as they don’t join some crazy federated groups etc

If you do, you can join this group: https://i.delta.chat/#6CBFF8FFD505C0FDEA20A66674F2916EA8FBEE99=&a=invitebot%40nine.testrun.org&g=ArcaneChat+Community&x=3KvvQZfzU4t-9u5s0PF3USGp&i=AQKH9_8x0R0&s=dbGW9xOhRQX

There are a lot of reasons for each of those will try to provide some at a glance:

SimpleX, XMPP, Matrix: The client is more user friendly, less buggy and less “this is for nerds” UI than the clients of those networks, ArcaneChat is more on the WhatsApp-like UI

Signal is centralized, depends on phone numbers so can’t be used by children in the family that don’t have access to SIM card yet etc. Registering in Signal is also more complicated, SMS verification, solving captcha etc. No good multi-account and multi-device as ArcaneChat.

Groups in ArcaneChat are managed independent of the server while in XMPP they are created on a given server and if the server dies the group is lost, while in matrix a lot of group state is replicated and tracked by the servers, in XMPP is easy to end up with unencrypted groups and in Matrix you often get “unable to decrypt” and emoji reaction are not even encrypted, ArcaneChat groups are always encrypted and safe against MITM (green checkmark displayed in the group name)

ArcaneChat has in-chat mini-apps that work independent of any server, communication is only between chat members and e2e encrypted, for example collaborative editor in chat, shopping list, split bill app, several mini games with shared scoreboards etc.

ArcaneChat works offline-first unlike many(all?) of the previous mentioned apps you can even create groups while being offline use and modify the in-chat apps and all state will be synchronized when you are back online. The app also works in slow and unstable connectivity when most of the other mentioned apps would simply not manage to connect.

Yes

If you do, you can join this group: https://i.delta.chat/#6CBFF8FFD505C0FDEA20A66674F2916EA8FBEE99=&a=invitebot%40nine.testrun.org&g=ArcaneChat+Community&x=3KvvQZfzU4t-9u5s0PF3USGp&i=AQKH9_8x0R0&s=dbGW9xOhRQX

btw, Matrix server requirements are much higher, and the client apps are less user-friendly

For example, arcanechat.me server has more than 1400 users and the server is using around 800MB of RAM, CPU is idle most of the time or really low usage, less than 3GB of disk (including whole Debian operative system etc)

Yes and no, it allows to login without providing any data or using any email account, in that case a random/anonymous account is created in arcanechat.me which is an email internally but optimized for chatting with similar speeds of other chatting platforms

Also with arcanechat.me server unencrypted messages are not allowed at all so you can be sure you don’t accidentally leak any message, also all messages are removed from the server immediately after downloading them (or after a few days when using multiple devices)
