what's inside
✍️
Away messages are back
The original microblog. Say where you went, then go there. "out. back when i'm back." Your whole personality in one line.
the classic
💬
Channels — three kinds
Public rooms anyone can join. Invite-only with expiring links. Secret channels that don't appear in search at all. You decide who gets in.
with slow mode
Topic communities built around a vibe, not a rulebook. No upvotes. No scores. The first 50 members get a founding member badge — forever.
no algorithm
🔒
Post-quantum encrypted
ML-KEM-768 post-quantum encryption. No ads. No data selling. No tracking pixels. We make money from $4/month Gold memberships and tips. That's it.

👥
Buddy lists, not followers
Both of you have to say yes. No follower counts. No vanity metrics. No strangers in your feed. Just the people you actually wanted.
mutual only
🌿
Disconnect proudly
Away mode is a feature, not a flaw. Log on. Say something real. Sign off and go live your life. We'll be here when you get back.

🔒
Built different. On purpose.
The internet used to feel safe because nobody was watching. We built Signoff the same way — the data never exists in the first place.
🔐
AES-256 + ML-KEM encryption
Two independent encryption layers — the same hybrid approach used by Apple and Signal. AES-256 is the gold standard used by governments worldwide. ML-KEM is post-quantum, built to resist future quantum computers. Both must fail simultaneously. We cannot read your messages. Not us. Not anyone.
post-quantum ready

We collect almost nothing
Your email is hashed the moment you register — we store a fingerprint, not your address. Your IP is never logged. No tracking pixels. No behavioral profiles. No "people you may know." We architected the system so the data never exists in the first place.
minimal footprint
Messages expire. Your device doesn't.
Messages expire from our servers after 30 days — there's nothing to subpoena after that because it's genuinely gone. Your device keeps everything locally, forever. The server is a relay. Your phone is the archive. Screenshots are king. This is how it worked before cloud storage made us lazy about privacy.

No algorithm. Ever.
Your feed is chronological. Always. No engagement scoring. No recommended content. No boosted posts. No content ranked by what makes you angry. You see what your buddies posted, in the order they posted it, then you sign off. The algorithm is how the internet started watching you. We don't have one.
chronological only
✏️
Write down your screenname.
We hash your email — we can't look you up without it. We don't store "last seen" timestamps. We can't recover a forgotten screenname. This is old school by design. Remember when AIM screennames were sacred? When you kept them in a notebook? When you screenshotted your buddy list before a new computer? That's this.
old school rules
🧹
Delete means delete.
Most apps keep your data in backup for 90 days "just in case." We hard delete everything the moment you confirm — posts, buddies, messages, history — gone from our servers immediately. No grace period. No soft delete. No "we'll keep this in case you change your mind." Gone is gone.
hard delete always

Remember when logging on felt like
going somewhere?

Before the algorithm. Before the metrics.
Before the internet started watching you back.

We're building that place again.
