LIVE TOPOLOGY · OFFICE LAN ALL LOCAL ✓
01 · Offline by design

Most workforce apps rent you a cloud. BossCheckin hands you the keys.

Others built their products around their servers — so you pay monthly, you depend on their uptime, and your payroll lives in their database. We built BossCheckin the other way around: everything runs on hardware you already own.

No server. No UPS. No IT department.

The boss's phone is the office: the database, the payroll engine, even the web dashboard all run on it. There's nothing to rack, patch, license or keep on backup power.

POWER CUT? Phones and the kiosk run on batteries — check-ins keep working.

Your data never leaves your phone.

Salaries, check-ins, photos, documents, chat — all stored encrypted on your own devices. We keep no copy. There is no central database of your business to hack, subpoena or leak.

WE COULDN'T READ YOUR PAYROLL EVEN IF WE WANTED TO.

Internet is an extra — not a requirement.

Devices find each other on your WiFi automatically. Want remote workers or reports from the beach? Flip on internet mode — sync travels through a relay as sealed ciphertext. Flip it off; everything still works.

THE RELAY SEES: ciphertext. THE RELAY READS: nothing.

02 · The big idea

Why rent a cloud, when it fits in your pocket?

A cloud is just three things: a server that's always on, one home for your data, and sync between devices. You get all three — except the server is the phone in your pocket, not a stranger's datacenter you pay for forever.

Their cloud

A meter that never stops

Their servers, their copy of your data, their invoice every month.

Your pocket cloud

The cloud is the phone

Your phone, your only copy, one payment and it's yours.

All the convenience of the cloud. None of the rent, none of the public attack surface.

03 · Check-in

Two ways to clock in. Zero ways to cheat.

Every check-in is a cryptographically signed, single-use token verified right there on the kiosk — no internet round-trip, no buddy-punching, no photographed QR codes.

QR code

Universal fallback
  1. Worker taps “Start” or “Finish” — the app renders a short-lived QR carrying a digitally signed token (who, what, when).
  2. The kiosk camera scans it and verifies the signature and intent on the spot.
  3. Green “Started” / red “Finished” — the entry lands straight in payroll. No network involved.

WORKS ON ANY DEVICE WITH A CAMERA AND A SCREEN

NFC tap

★ Recommended
  1. Worker taps their phone on the kiosk — a ~4 cm radio handshake, nothing to aim or focus.
  2. The kiosk issues a one-time challenge; the phone answers with a signed response. It can't be replayed, photographed or forwarded.
  3. The kiosk works locked, even with its screen off — a cheap phone in a drawer becomes a check-in terminal.

BEST WITH AN ANDROID 12+ PHONE OR TABLET AS THE KIOSK

You pick the method per kiosk — we recommend NFC. It's faster, can't be photographed, and the kiosk keeps working locked with the screen off; for best compatibility use an Android 12 or newer phone or tablet as the kiosk. Both methods carry the same Ed25519-signed token and both are verified locally — a worker physically present is the only thing that produces a valid check-in. Devices without NFC simply use the QR path.

As far as we know, we're the only attendance app doing phone-to-phone NFC. Elsewhere “NFC” typically means a passive tag stuck on a wall or a badge card on a dedicated reader — a tag marks a place, can be cloned, and proves nothing about who tapped it. With BossCheckin both ends are ordinary phones, and every tap is a live cryptographic exchange: a signed, single-use token. Nothing static, nothing cloneable, no extra hardware to buy.

It can open your door, gate or barrier too. An integration API connects BossCheckin to your existing access hardware — a valid check-in can trigger an electric door, a gate or a parking barrier to open, right there on your premises. Ask us about your hardware →

04 · Office Web

A full web dashboard — served by your phone, not the internet.

Your phone quietly runs a tiny encrypted web server. Open its address in any browser on the office WiFi and you get a complete back office — with the internet cable unplugged.

The whole office in a tab. Employees, sites, check-ins, payments, absences, leave, chat, photos, documents, a recycle bin and settings — manageable from a laptop, in bulk.

Reports your accountant will love. Monthly payroll, payments, absences, leave balances — exported as spreadsheet-ready CSV. Give the accountant a restricted account that sees only Reports.

Delegate the busywork. Helper roles keep the boss out of tech support: a Key Manager takes care of workers who change phones — activating the new device so the boss never deals with it — and a Maintenance role instantly sees exactly which kiosk is misbehaving and gets it back online the fastest way.

Bring your own AI — even a fully local one. BossCheckin ships a standard MCP endpoint that runs on your own phone. Point your AI assistant at it: Claude, or a model running entirely on your own computer, offline. Where competitors offer AI at all, it lives in their cloud and reads their copy of your data — to our knowledge, BossCheckin is the only workforce app where AI access involves no vendor cloud at all. Opt-in, read-only, token-protected; chat is never exposed.

05 · The rest of the toolbox

Small business outside. Serious machinery inside.

Payslips on every worker's phone

Each employee sees their payslip and a live calendar of their check-ins — today's start and finish included, not last month's news.

Chat, split the right way

Three separate spaces: office ↔ worker (the official channel — visible to the office team, kept in the business records), office ↔ office (private manager DMs), and worker ↔ worker — end-to-end private between colleagues: not even the boss can read it, and it never lands in the office backup. Photos + Sent → Delivered → Seen everywhere.

Documents with expiry alarms

Attach ID or licence scans to an employee with an expiry date. Both you and the worker get reminded before it lapses — not after the fine.

Paid leave & sick days

Yearly allowance that grows with tenure, half-day precision, and a three-colour calendar: absence, paid leave, sick — payroll adjusts itself.

Kiosk mode

Turn a cheap tablet into a dedicated check-in terminal, locked to the job — workers can't exit it, browse, or “accidentally” uninstall it.

Multi-site, even with no signal

Kiosks relay chat between each other over the LAN. Sites with zero coverage? A courier phone physically ferries encrypted data between locations.

Backups you actually control

Three independent restore paths: backup kiosks, courier phones and your own Google Drive — designate as many backup kiosks and couriers as you like. Lost your phone? A 12-word phrase restores everything.

Recycle bin + GDPR auto-scrub

Deleted records can be restored with one tap. Ex-employees' personal data auto-erases after a period you set — while payroll history stays, as the law requires.

Internet mode — one switch

Remote worker? Flip the switch: sync flows through a relay as sealed ciphertext the relay cannot read. Messages and sync each get their own toggle.

06 · Never lose a thing

“But what if the phone breaks?” You lose nothing.

The one fair worry about a phone-as-server: what if it's lost, stolen or smashed? That's why your data is constantly mirrored — encrypted — to backups you control. A new phone, a 12-word phrase, and everything comes back.

BACKUP KIOSK GOOGLE DRIVE COURIER LOST / BROKEN 12-WORD PHRASE
BACKS UP CONTINUOUSLY · 3 INDEPENDENT COPIES RESTORE → NOTHING LOST ✓

Backup kiosks, a courier phone, and your own Google Drive — as many as you like. Lose the phone, keep the business.

07 · Security

Encrypted twice. Readable once — by you.

Security isn't a feature here; it's the architecture. The system assumes networks are hostile and middlemen are nosy — and works anyway.

Encrypted at rest, on every device

The database is SQLCipher-encrypted and photos & documents live in an encrypted vault — on the boss's phone, the kiosks and every worker's phone.

Sealed in transit, end to end

Every device-to-device channel is sealed with libsodium (X25519 + XSalsa20-Poly1305). Chat is additionally sealed per message and per photo.

A signed, append-only history

Every record is an Ed25519-signed entry in a tamper-evident chain. If anything is altered, the signatures stop matching — quietly editing the books is not a thing.

Blind middlemen, by construction

The optional relay, the kiosks and Cloudflare forward frames they cannot open. Your payroll decrypts in exactly one place: on your devices.

Your keys, your kingdom

Identity lives in a 12-word recovery phrase only you hold. We can't reset it, recover it — or be compelled to hand over what we never had.

08 · The honest comparison

BossCheckin vs. Others

“Others” being the typical cloud workforce suite: a browser login, a monthly invoice, and a quiet dependency on someone else's servers.

The pricing math 10 employees · 3 years
BossCheckin
€100 — once
Cheapest cloud suite
≈ $1,220
Typical cloud suite
≈ $2,160
Pricier cloud suite
≈ $4,680

That's ≈95% less than a typical cloud suite over three years — and the gap only widens, because one-time keys don't renew. By year five it's ~97%.

BossCheckin: €10 per employee, one-time activation key — a worker's device then serves for years. “Others”: the cheapest adequate paid plan with an attendance kiosk across nine mainstream cloud workforce suites, per-user list prices billed annually (June 2026) — roughly $3–13 per user per month effective (typical ≈$6), base fees included where charged. Some vendors offer free tiers with limits (one kiosk, one location, up to 10 users) — fine until you grow, and your data still lives in their cloud either way.

And this is only the beginning. BossCheckin is in active development — new capabilities ship steadily, so expect this table to keep growing in one direction.

09 · Questions

Asked & answered.

Do I really not need a server or a subscription to a cloud?+

Really. The boss's phone stores the data, computes the payroll and even serves the web dashboard. Devices talk to each other directly over your WiFi. The only online services that exist — license activation and the optional relay — carry no business content and are not needed for daily work.

What happens if the boss's phone is lost or dies?+

You restore from your encrypted backups: your own Google Drive and/or a designated backup kiosk that has been quietly mirroring the encrypted history. Enter your 12-word recovery phrase on a new phone, re-pair, and everything — records, photos, documents — comes back. Guard the phrase: it's the one thing we cannot recover for you.

If I turn on internet mode, what does the relay actually see?+

Sealed frames: an opaque blob of ciphertext, a routing identifier and a size. It cannot decrypt content, it stores nothing, and switching it off changes nothing about local operation. Think of it as a courier who can't open the envelopes.

Do my workers need internet or a data plan?+

Not for the core job. Checking in is a local act — a QR scan or an NFC tap at the kiosk. Payslips, chat and the live calendar sync whenever the worker's phone shares a network with the office (or over the optional relay if you enable internet mode).
