Sealr Chat vs ANCROM

Sealr is private messaging built around one idea: your text and your media stay under your control - even after you hit send. Every message and every photo, video, voice note and document is end-to-end encrypted. Not even Sealr can read them. But Sealr goes further than encryption. You decide the rules for each message: • Views - let it be opened a set number of times, then it's gone. • Expiry - set a moment after which the message disappears. • Geo-fence - lock a message so it can only be opened in a place you choose. • Keyhole - reveal only a small part of a photo or document; the rest stays hidden. • Ghost capture - take a photo or video that goes straight into the chat, encrypted, and never touches the recipient's gallery. More privacy by design: • No profile pictures, no public profiles. • Screen-capture and screen-mirroring are blocked while Sealr is open. • Group chats with encrypted titles. • Find friends by phone or email, or scan a QR code - no usernames to leak. Your text. Your media. Your rules.

ANCROM - Private Messaging ANCROM is a messenger for people who want their conversations to stay between them and the person they are talking to. No phone number, no email address, no address book upload. SECURITY BUILT ON STANDARDS End-to-end encryption with post-quantum protection Messages are encrypted on your device and can only be read by your contact. Keys are agreed using a hybrid method that combines ML-KEM-1024 and elliptic-curve cryptography (P-384), so conversations stay protected even against future quantum computers. Messages are encrypted with AES-256-GCM. A fresh key for every message Keys change with every message (forward secrecy). Even if a key were ever exposed, earlier messages stay protected, and the conversation recovers on its own. Sealed Sender Each message is encrypted as a whole before it leaves your device. Our relay servers only learn where to deliver it - not who sent it. Verified contacts Add contacts by scanning their QR code in person. Far apart? One of you creates a one-time code and reads it out, for example on a phone call; the other types it in. Both phones then show the same six-digit number - compare it before you confirm. You can also compare a safety number in the chat at any time. If a contact's security key ever changes, ANCROM warns you and pauses the conversation until you verify again. NOTHING STORED THAT ISN'T NEEDED Short-lived relay storage Our servers only pass messages on. A message is held until your contact's device confirms it, for at most 24 hours, and then deleted. Your data stays on your device Chats are stored only on your phone, in an encrypted database protected by your password. No cloud sync, no server-side history. Protected sign-up No phone number, no email address, no personal information required. Clean photos Location, camera details and other metadata are removed from images before sending. PROTECTION ON YOUR DEVICE - Screenshot protection - Auto-delete for messages - Duress PIN and panic button to wipe your data instantly - Detection of jailbroken or manipulated devices Only people you add can reach you. Messages from strangers are not shown until you add them yourself. GOOD TO KNOW Your privacy comes with responsibility: because nothing is stored in the cloud, your chats are gone if you delete the app or lose your device. There is no recovery, by design.
