How it works
Choose your backup team
Pick the people you trust most and share your secret identity code with them — show a QR or send it over Signal.
Live your life with plans
Set one‑time or repeating Plans that match your nights out, adventures, or demanding work. BackBy checks in to make sure you got back from your plans safe and sound.
If you miss a check‑in
Your Backers are alerted automatically. They’ll reach out, and — if you chose — unlock your note to help you quickly.
Get BackBy
BackBy is an edge device app — it runs on your phone. No accounts, no trackers, no IP logs.
What makes BackBy different
We don’t send messages
Backers pull info when they choose. That keeps your contacts and conversations off our servers.
We don’t keep personal data
No accounts, no cookies, no IP logs. Your note is encrypted on your device; we can’t read it.
You can verify history
Our public, append‑only history can be mirrored. If one site goes down, your Plans remain verifiable.
Privacy, by design
- No accounts, cookies, or analytics. Ever.
- We don’t keep IP addresses at the app or proxy.
- Notes are encrypted on your device; we can’t read them.
- Your people pull info when they choose; we never send messages.
- History is append‑only and publicly auditable.
Built to last
After some community apps disappeared, people lost a lifeline overnight. BackBy avoids single points of failure: we don’t run a messaging service, we don’t hold personal data, and our public history can be mirrored. If one site goes down, your Plans remain verifiable and your notes stay yours.
Why BackBy won’t be taken downFor organizations
Nightlife venues, outdoor clubs, and immigrant‑rights groups use BackBy to set clear expectations and reduce panic.
- Share BackBy in onboarding and safety briefings.
- Offer a poster or QR at exits — “Set a BackBy before you go.”
- Provide a contact list your community can include in their notes.
Frequently asked questions
Is this a messaging app?
No. BackBy never sends messages. Your people check Plans when they choose, then act using the tools you already trust.
Do you track me or keep my info?
No. We don’t keep IP addresses, names, contacts, or cookies. Only pseudonymous Plan events and your optional encrypted note.
What if BackBy goes away?
Plans are append‑only with a signed history that mirrors can host. Your Backers can still verify state and unlock your note off‑platform.
Who is BackBy for?
Equally for a night out, solo outdoor trips, and people facing legal risk. The core idea is simple: a check‑in time and a calm plan.
