Shift workers, nurses, drivers, freelancers — Logifi is designed around variable income, UK tax rules, and the reality that your pay arrives after a cut-off, not the day you earn it.
One-tap shift templates, multiple jobs, rates locked in at what you actually earned — a pay rise never rewrites your history.
Set your payday and cut-off; Logifi models pay-in-arrears correctly and shows the full working behind every figure.
HMRC income tax, NI, all 5 student loan plans on current 2026/27 thresholds, pension — and a one-tap Self-Assessment Tax Pack.
On-device AI reads the merchant, total and date. The photo never leaves your phone.
Spending momentum, your priciest weekday, work-hours vs food-spend — patterns computed privately on your device.
A journal no company can read. PIN-locked, biometric unlock, photos encrypted alongside text.
MOT, tax & insurance reminders before they lapse, true monthly cost, cost-per-mile, encrypted documents.
Credentials and identity documents in an AES-256 vault only your PIN can open.
Every Sunday: earned, spent, streaks — a summary made for you, seen only by you.
Everything below is verifiable behaviour, not marketing. Ask us hard questions — we like them.



One optional PRO purchase through Google Play — lifetime or annual. Payment is handled entirely by Google; we never see your card. That's the whole business model: you pay for software, not with your data.
Check for yourself: Android's network usage screen, or any packet-capture tool, will show you the complete egress list above — and nothing else. There is no analytics SDK in the APK to find.
Nothing — that's the point of local-first. Your data lives in files on your device, and the export produces a standard JSON backup you always control. There's no server to switch off.
Restore your encrypted backup (Drive or file) on a new device and enter your PIN. Backups carry their own key material, so they restore anywhere — but without your PIN, they're AES-256 ciphertext to everyone, including us.
The engine uses year-keyed HMRC tables — income tax with allowance taper, employee NI, all five student loan plans on current 2026/27 thresholds, and salary-sacrifice pension. Historical payslips compute with the rates that applied that year. It's an estimate for planning, not filing advice.
