Sojourn Group · Dubai
Built for lives
that cross borders.
Four apps for people who live, work and fly between countries — and have to prove where they were.
- Sojourn Tax counts your days against the 183-day rule, Schengen’s 90/180 and the US Substantial Presence Test, country by country, and exports a tax-residency record an authority can verify.
- Sojourn Logbook is the pilot and cabin crew logbook that also runs your flight time limitations — duty, rest and the cumulative limits — from each authority’s own rules.
- Sojourn Social shows you who you know within reach, wherever you land. A useful, focused feed; no popularity contest.
- Sojourn Financial is the finance that has to follow a life with no settled address.
What we stand for
- Accessible
- Built for everyone whose life crosses borders, not only those with an advisor on call — and more so as Social and Financial arrive.
- Affordable
- Fair prices for products that do real work. Keeping a record should never cost more than the problem it protects you from.
- Built with the latest technology
- Knowledge and dedication, combined with the latest tech. We use the new tools where they make a product genuinely better — Sojourn Tax already ships an AI agent — and nowhere else.
- Ready for the next financial system
- Blockchain and what follows it are changing how money and proof move. Sojourn is built for that world, not the one before it.
Every Sojourn app works from your own facts — days, hours, people, money — kept on your device, never on ours. Tax and Logbook are in beta testing.
A week in Amsterdam, then home to Dubai. One journey, four questions. How many days did it cost against a residency limit? If you fly for a living, how many hours did it add to your licence? Who you know was within reach while you were there? And when you want to buy a home, who lends to someone with no settled address?
In beta testing
Two of the four are nearly here.
Sojourn Tax documents where you were, for residency. Sojourn Logbook is the working record for pilots and cabin crew. Both go live together on iOS and Android. Sojourn Social is in development, and so is Sojourn Financial.

Sojourn Tax™
Every country counts a day differently. The UK ignores the day you leave. The US weights three years at once. Sojourn applies each country's own rule to your own movements, and produces a record built to be handed to a tax authority: checksummed, signed, verifiable by anyone who receives it.
Read as hours
Sojourn Logbook™In beta testing
Every authority defines a night hour differently, and command time twice over. Most logbooks pick one definition and hope you never move country. Sojourn stores the flight as it happened and computes each authority's columns at export, so the same record files correctly with the FAA and with EASA.
Keeping your hours is only half the job. The same record runs your flight-time limitations — duty, rest, and the cumulative limits — against the authority you fly under, so you know not just what you have flown, but where you stand. Figures are indicative — confirm against your Operations Manual. Not legal advice.
Who flies under them
One record, filed correctly wherever your licence sits.
A few of the majors under each authority, to show the shape of it. Sojourn is not limited to them — if you fly under one of these authorities you can use it, whatever the operator: airline, cargo, charter, corporate, air ambulance, survey or flight school. The authority governs your logbook, not your employer.

Sojourn Financial™Planned
Work in one country, live in another, and financing quietly stops working. Lenders want a settled address, a local salary, and years of history in one place. People who move for a living have none of those on paper, and get refused for a home they could comfortably afford — in the country they work in, and in the one they came from.
It is the same gap the rest of Sojourn exists to close: your life is documented, just not in the form anyone will accept. We are working on it, and we will say more when there is something to say.
The record is the product.
Whatever a Sojourn app counts, it ends in a document someone else will accept — a tax authority, a chief pilot, a lender. A few of them below; each app can produce more. Every one carries the holder’s identity, the rule behind each figure, the source of every entry, and a checksum over the whole — so anyone who receives it can check it.

Sojourn TaxTax-residency record · hand it to the authorityPer-country day counts under each country’s own rule, with the review date of that rule, every stay and its source, and a SHA-256 checksum. Change one character and the checksum breaks; anyone who receives the file can confirm it in a browser — no account, no upload.

- Career Summary · the CV you send: licence, medical, totals, PIC and night hours. Cabin crew get their own edition — attestation, rank, duty hours, time in charge.
- Authority logbook · your record in the authority’s own columns (the GCAA twelve-column AMC1 FCL.050 layout here), night and pilot-function time computed to each authority’s definition at export.
- FTL proof-of-record · duty, rest and the cumulative limits over a period, against the rules you actually flew under, a citation on every figure.
- …and others: a crew-rest log, an airline application pack, a hand-off to Sojourn Tax.
Your records are not our data.
We built it so we couldn't read them.
Sojourn Tax keeps your history on your device and nowhere else. Sojourn Logbook, where losing the record would cost a career, keeps an encrypted copy — sealed on your device, with a key that never reaches us. Not a policy we could revise later. An architecture: there is nothing for us to hand over, and nothing for anyone to take.

Sojourn Social™In development
The social platform that is actually useful. Network with people who call the world their home, earn cash back while you do, and leave the social drama behind. Built for function and networking, not for watching how other people live.
The test for every feature is whether it helps someone get something done or meet someone useful. So the feed is useful and focused, not a popularity contest run on follower counts. And your location is kept deliberately inexact, inside a margin, for privacy and safety; it becomes precise only under conditions you control.
