Every conversation end-to-end encrypted. Two-thirds of net profit goes to clean water; the rest keeps SUcure running. A calm, honest tool with a reason behind it.
Audited Matrix encryption underneath. A warm, plain, accessible experience on top.
Messages, calls and files are sealed on your device. The key is yours alone — not ours.
Your attention isn't for sale and your data is never mined. The model is plainly honest.
Built on the open Matrix standard, with your conversations under your control.
Voice, video, rooms, replies, reactions and polls — every part encrypted end to end.
Large tap targets, strong contrast, readable type and a true dark mode. No manual required.
The mission isn't a badge on a finished product. Funding water is why SUcure exists at all.
of net profit becomes clean water. The remaining third keeps SUcure running — that's all of it.
We don't measure ourselves in revenue. We measure ourselves in mornings that begin with clean water close at hand.
The counters above open at launch and only ever climb. Behind each number sit real places and real people — every figure traceable to the project that earned it, mirrored inside the app. A quiet promise, kept in the open.
SUcure is a respectful fork of Element X, the actively maintained Matrix client. We adopt its audited encryption exactly as it stands and never reinvent it. The whole project is open under AGPLv3 — readable, auditable, free to fork.
