Dortmund's FanModus: Ninety Minutes, Ninety Points, and an App That Measures Your Presence

The version number changed on the app store on a Tuesday afternoon. By Friday evening, the lower tier of the south stand knew that sitting in your seat was no longer enough — the app had to stay open in your pocket.

Signal Iduna Park takes 81,365 people on a league matchday, and roughly twenty-five thousand of them stand on the single terrace that gets called the Yellow Wall. I was not standing there. I was at a desk in Kolkata, where the clock on the screen read evening and a fan turned in the room. But from the moment the FanModus story landed, one old habit came back — the one I learned in the mixed zone at Salt Lake: read the announcement, then go and find out whose signature is actually on it.

The contract arrived on a Tuesday; by Friday, the terrace already knew. The terrace always knows.

What was announced is a count — one minute, one point. One point for every minute a fan is present inside the stadium, capped at ninety points per match. Ninety minutes, ninety points. The prize list is signed jerseys and club-store vouchers. The whole scheme collapses into two lines, and that is the most interesting thing about it. A club that has played Champions League finals is converting its largest crowd into a per-minute arithmetic. The date is equally clear: the home fixture against Eintracht Frankfurt, Saturday, 24 October, at Signal Iduna Park. The club tied the launch to that fixture. That is the first thing I look for in any press release — the date. Everything else comes later.

Pause on the name. In German, aeroplane mode is 'Flugmodus'. The club called it 'FanModus'. The pun looks harmless, but the philosophy is inside it: you are being asked to come out of flight mode and into fan mode. Not to switch the phone off. To switch it on.

The real currency of the Bundesliga

You cannot read this scheme without the economic architecture of German football. The Bundesliga has the 50+1 rule, which requires the parent members' association of any club to retain a majority. The direct consequence is that outside investors cannot buy a club. Dortmund is counted among the largest member-owned clubs in the world, and that is part of its identity.

One side of that rule gets written about less: when the door for capital is closed by statute, a club sells what is not closed. You cannot sell shares, so you sell attention. You cannot sell seats, so you sell the data of the person sitting in the seat. Read FanModus purely as a fan-friendly initiative and you will miss the financial need that produced it.

That need is real. After European football's broadcast-rights curve rose and then flattened, 'first-party data' became a magic phrase for every large club — the information you hold about your own audience, owing nothing to an agency or a platform. Who comes, how often, to which match, spending what. That is the inventory sponsors pay for, because sponsors do not want advertising, they want identification.

The survey the club did not commission

Behind the club's argument sits one number. In a 2026 Vodafone survey, 63 per cent of 1,000 regular stadium attendees said they used a smartphone regularly during matches.

The number is true and the number is incomplete, both at once. True because you can see it in any stand — in my own experience, even inside the 66,684 crowd at the 2026 Under-17 World Cup final at Salt Lake, phones kept ringing. Incomplete because the survey is not Dortmund's, is not from this season, and comes from a telecom company with its own interest in phones being used. The club turned a third party's data point into proof of its own problem.

I recognise the technique. In Indian football too, whenever a decision runs into trouble, the first thing produced is a statistic that is accurate and has no direct relationship to the decision.

What FanModus actually is

Now to the thing the club calls 'enjoying football' and a technologist would call 'geolocation-based presence verification'.

The club has stated plainly that participation is voluntary. The club has also stated plainly that confirming presence in the stadium requires location permission. Read those two sentences together, literally. The first gives you the right to walk out. The second tells you the condition of walking in. And between them sits the thing neither sentence mentions — the raffle, the jersey, the voucher.

Voluntariness when there is a prize attached. No fan standing for ninety minutes is being told to open the app. He is being told that if he does not, the man beside him who does will move ahead of him. The monetary value of a signed jersey is zero; its emotional value to someone who has stood on that terrace for ten years is not. Here voluntariness is true on paper and a social pressure in behaviour.

This is where I have to be clause-literal, because that is the job. A contract saying 'optional' and a contract being optional in practice are two different things. In 2026 I was handed a redacted pre-contract whose trigger clause was drafted so clearly no lawyer was needed, and the club still called it fabrication. The distance between the paper and the announcement is the whole story.

The cost you cannot see

On the surface this is a cheap deal. Add a feature to the app, write the points logic, sign a few jerseys, print a few vouchers. Total spend? No big number.

A clause-literal man reads cost from absence, not from the announcement. What is not in the announcement: app development and maintenance, raffle administration, winner verification, secure storage of location data, and the largest item — compliance with German data protection law. In Germany the data protection officer arrangement is a serious matter, and any app-based initiative arrives with a document no fan ever reads: the privacy notice.

The most important document in this entire project is the one nobody will read. That notice will state how long data is retained, who it is shared with, on whose servers the processor sits, and how a fan can have it erased. If you want to know the real shape of this scheme, do not watch the press conference. Watch the version number on the privacy notice.

The real product is identity, not attention

The club says it wants people watching the pitch instead of the screen. I read it from the other side.

FanModus is a presence-verification system, not an attention-measurement system. It does not tell you whether a fan watched. It tells you that he remained inside a geographic boundary for ninety minutes with the app open. You can stare at the roof instead of the pitch, you can spend sixty minutes of half-time in the toilet — the points keep coming. What is being called 'winning attention back' is technically 'logging presence'. The gap is not small. Presence gets logged. Attention does not.

And what logging presence gives the club is far more valuable than attention. Attention cannot be sold. A record of presence can.

From here the commercial picture sharpens. The club already holds ticket data — who buys which match. FanModus adds a layer: who stayed inside how long, which match, which weather. That is gold for a CRM system, because it segments a fanbase — the every-weeker, the big-match-only, the one who comes with children, the north-stand regular. And on the day the club can tell a sponsor that it has three hundred thousand fans who are present at least twelve times a season and are connected through the app, the arithmetic of this whole exercise closes.

The club has not yet announced any sponsor involvement. That is the biggest signal for me. This is phase one. Phase one is always free, because first you build the habit.

Who is standing in the corridor

You learn more from the corridor than from the press conference, and here the corridor is digital.

There are at least four intermediaries in this scheme, and none of them is the captain. First, the app vendor who built or bolted on the module. Second, the data processor — the company on whose servers location data will sit, probably inside the European Union but not necessarily inside Germany. Third, the club's fan liaison officer, the person who will open seventy emails on Monday morning, half asking why the app is broken and half asking why their data is being taken. Fourth, the data protection officer, whose job is to make the privacy notice legally sound and human to read — two things that are hard together.

None of these four will be standing on the terrace the scheme was built for. That is the old law of middleman economics. What reaches the fan passes through many hands, and every hand adds a condition. I have watched this repeatedly in Indian football — the journey from an I-League club to an ISL club is decided not by a player's feet but by an agent's phone. Here the player is replaced by fan data, nothing more.

Accountability in a member club

One thing stops this story from being pure marketing news — Dortmund's member-based structure.

At a privately owned club the only question would be whether the scheme works. Here there is an extra layer: the members. At the members' assembly it can be asked where location data goes, who receives it, and whether it will ever be shared with a sponsor. Whether the question gets asked is another matter. That the room exists matters.

The club that built the 50+1 wall must now find revenue inside it. Data is the road with no rule on it. You cannot sell shares, but you can build a product whose customer is a sponsor and whose raw material is a fan. Like it or not, that is the logical outcome of the Bundesliga's economic structure.

This is where the map of my own home returns. Indian clubs do not even have that option, because they do not have the raw material. The 2026-21 ISL season was played behind closed doors across three Goa grounds — Fatorda, Tilak Maidan, GMC Athletic Stadium. That year, letters went out at two clubs for 30 per cent wage deferrals over six months, and force majeure clauses were inserted in October 2026 with no player consultation. On a podcast I called it a transfer of risk. Off air, I was angrier than I have ever been on record.

The root of that anger was that Indian clubs held no organised record of a fan's name, number or attendance. When the stadiums emptied, there was no contact list to speak of. European clubs are now hardening that same contact list through an app. That is the difference — on one side a list being built that will matter in a crisis, on the other a crisis arriving to reveal there was no list.

The blind spot in the official story

Now the part that stings most.

The club's defence is public. Carsten Cramer said openly that this is about the enjoyment of live football. I am not questioning his intent. I am questioning the fact that he had to defend it. No senior executive pre-emptively defends a scheme unless, somewhere inside, he expects the criticism to arrive. The existence of the defence tells you the club discussed whether this could be read as surveillance.

The real contradiction is this, and no press release resolves it. The stated aim is: use your phone less. The mechanism is: open the app, grant location, keep it live for ninety minutes. You are asking people to increase the use of a device whose use you say you want to reduce. That contradiction cannot be avoided, only hidden.

Second, and finer. The 63 per cent figure says people use phones during matches. It does not say the phone is spoiling the match. Perhaps they are checking the half-time score, perhaps messaging a sick mother at home, perhaps finding a friend in the next stand. The statistic measures phone use. It does not measure distraction. Treating the two as one is convenient, and the whole case rests on that convenience.

Third, and least said. Look at the prize list — jerseys and vouchers. That is where the scheme stops being fan service and becomes behaviour management. When you award points to a behaviour, you rank it above other behaviours. The fan who stands and sings for ninety minutes scores the same as the one who leaves in the seventieth for a beer and leaves the app running. There are no points for singing. No points for standing. Only for the app. What the club calls its greatest strength — the Yellow Wall, the noise, the atmosphere — has no score in this arithmetic.

When points become currency

For now the points are only a raffle ticket. That is the safest state, because nothing can be lost.

I worry about the next state, which usually arrives. First points for raffles. Then points for priority — the big-match ticket, the away-day allocation, the cup final ballot. Ticket allocation is already sensitive at German clubs because demand far exceeds supply. If one day it is said that away tickets for Eintracht Frankfurt favour 'active app users', where does the sentence about voluntariness go?

Here is what I call the price of non-participation. As long as taking part only brings a benefit, everything is fine. The day not taking part costs something — a lower place in the queue, a later allocation, a condition on membership — the scheme stops being fan service. And that day will not arrive loudly. It will arrive as an amendment to a rulebook nobody reads.

I have watched this pattern closely in Indian administration, which is why I am spending this much time on it. The August 2026 FIFA suspension, the normalisation committee — the pattern was always the same. First a technical step, then an interpretation, then a rule nobody mentions. You do not see a disaster. You see a document whose version number has changed.

The next domino

So what should be watched? Three things, all of them in documents rather than statements.

First, the sponsor entry. The day a brand name attaches to FanModus points or prizes, the scheme turns from fan service into advertising inventory. That announcement will never use the word monetisation. It will be called a partnership.

Second, the privacy notice version. If a data-sharing clause is added, phase one is over.

Third, any link to ticket allocation. It will come last and matter most.

For those who think this is only an app, one last thing. On the evening of 24 October, when the Yellow Wall stands up at Signal Iduna Park, thousands of those pockets will hold an app quietly counting. I do not know what that count will be used for. I know that counting is never free.

The question is not what Dortmund asked of its fans. It is what the fans gave, and what they got in return — and whether that ledger is raised at next season's members' assembly.
