SagMal vs Obliv

SagMal ("Tell Me" in German) is a new chatting app like no other, where the foremost is your privacy. • You provide absolutely nothing of your personal details when registering. No phone, no e-mail. Therefore, there is no way your personal data can be stolen or given away. • We use doble encoding using state-of-the art encoding algorithms. You can easily encode any chat and it won’t be even obvious that it’s encoded (see 3 first screenshots) to your significant other or any official. • Messages are deleted from the server as soon as they're delivered. And the servers are based in neutral Switzerland, unreachable to most of the the Big Brothers. • It’s very easy to change pictures and names of your contacts so that your significant other or the authorities won’t suspect who you’re talking to. • This app is ideal for: o Wife/husband cheaters, you will be very difficult to catch o Anyone who is not willing to receive targeted advertisement, or who simply doesn’t want to give away your personal details o Anyone willing to go or to organize a meeting that has not been authorized by the State. The Big Brother will have a hard time catching you We use double encoding with state-of-the-art encoding algorithms where nobody (even us) can decode your messages. To enable double-encoding set the chatroom password at the beginning and let it know to whoever you're chatting to right away. For extra safety do not use chat to inform about your chatroom password. Note that your chat messages are encoded anyways (even if you don't provide an extra password), but with this additional password you get a second encoding on top of the first one. And not only text but all the images are encoded as well. Here is an incomplete list of SagMal chat features: - No need to give your phone or E-mail when registering. Just the good old way of providing a username and a password. - We delete all messages from our servers as soon as they are delivered. - There are no "bots" like in some other messaging apps that can provide anyone with your registration information, nicknames, etc. - Our servers and hosting are located in neutral Switzerland. - Your personal data can't be stolen from our servers - just because there is no personal data available - we don't know your e-mail and phone number. - But this is not all - for each chat window you have the possibility to encode the chat contents with a unique key that we won't know. You just let this key know to your chat counterpart. - Using a key you can easily encode your chat. This is the way to have private conversations that won't be seen by your husband or your wife, your parents or authorities. Also photos will be encoded as well! - SagMal chat app protects you from your "Big brother" - there is no way they will know that you plan to go to a meeting where you're not supposed to go. - Very easy to delete messages, from both, yours and your counterpart devices. You can also set how long a message will live before it will be automatically deleted. - Possibility to have multiple accounts on the same device. Very easy to switch between accounts. - Delete a contact or add it to a blocked list is easy by swiping a contact to the left. - Refresh contact list or data from the server by pulling the view down. - Messages just sent are in italic font, received by the server are in normal font and received by the user are in bold. Please let us know if you find any bugs or wish to see some improvements or new features. The app is free to send text, audio messages, images and small videos (up to 10 MB per day). If you want to send larger media files you can purchase a subscription which renews monthly .

Obliv is a messenger for people who want their conversations to actually disappear. No phone number. No email. No backups. No recovery. Just a six-digit PIN you memorise, and messages that vanish from our servers the moment your device acknowledges them. End-to-end encrypted on your device before anything leaves it. The server is zero-knowledge — it cannot read, index, or recover what you send. Features • Text, photo, video, voice notes, and files • Encrypted audio and video calls with native iOS call integration • Private group chats with automatic key rotation when membership changes • Contact exchange by QR code or short ID — no directory, no lookups, no phone book • Panic wipe after repeated wrong PIN attempts. No recovery. No exceptions. • Screenshot and screen-recording protection on sensitive screens • No analytics. No crash reporting. No advertising. No third-party tracking. • PIN-only unlock. No biometrics. No device-key storage. Threat model Obliv is designed for people who expect their devices to be seized, inspected, or lost. Your identity lives on-device, encrypted with a key derived from your PIN using a slow, brute-force-resistant function. Biometrics are deliberately unsupported — no one can unlock Obliv by holding your phone up to your face. If you forget your PIN, the identity is gone. This is the point. What we store On our servers: public keys so peers can find you, transient encrypted envelopes that are deleted the moment your device acknowledges them, and opaque push tokens for wake-up notifications. Nothing else. No message content, no contact lists, no conversation history, no behavioural data. Limitations Obliv is intentionally single-device. Multi-device support widens the attack surface and is not supported. If you reset your phone or reinstall Obliv, you start over. Obliv is independent. Not affiliated with Signal, Telegram, WhatsApp, or any other messenger.
