Privacy Policy

ochestra apps & website · Last updated: 26 July 2026

This policy explains what the ochestra darts apps — counter and tournament — do with information, and what this website does. It also covers the guest view at join.ochestra.ch, which is how players follow a tournament in a browser.

The short version: there is no advertising, no analytics and no tracking of any kind, and we do not build profiles of anyone. counter sends nothing anywhere — it has no network connection at all. tournament shares one thing: the tournament itself, so that everyone in the room can follow it on their own phone.

Who is responsible

BOFF GmbH, Sickingerstrasse 10, 3014 Bern, Switzerland — the controller for the processing described here. Questions, requests and complaints: info@boff.ch.

counter — nothing leaves your device

Everything you create in counter — player names, scores, running games, match history and settings — is stored only on your device, so your games are still there when you come back. The app makes no network requests whatsoever and works fully offline. We receive nothing from it and cannot see it. Deleting the app deletes this data with it.

tournament — what is shared, and with whom

A tournament is meant to be followed by everyone playing it, so it has to leave the host's phone. While you host a tournament, the following is stored in our database (Firebase Realtime Database, provided by Google as our processor, hosted in the EU / Belgium):

• the tournament name and the player names the host types in
• the schedule, board assignments, match results, bracket and standings
• result submissions that guests send in for the host to confirm
• a random identifier of the hosting device or account (see below), so that only the host can change the tournament
• for the host's own recovery list: the name, stage, number of players and number of played matches of each of their tournaments, plus the time of the last change

Who can see a tournament. Anyone who has its QR code or link can read that tournament — that is the entire point of the QR code, and there is no password in front of it. The link contains a long random identifier, so a tournament is not findable by guessing or by browsing, but it is not secret either: whoever receives the link can pass it on. Only the host can change the tournament; everyone else can look and submit results for confirmation.

Player names are free text. You choose what to type, and a nickname or a first name works just as well as a full name. Do not enter anything you would not want the other players — or anyone they forward the link to — to read. If you enter other people's names, please see “Names of other people” in our Terms of Use.

tournament — how a device is recognised

So that only the organiser can change a running tournament, the app signs in anonymously in the background the first time it starts. This is not an account: it is a random identifier tied to that installation. It asks you for nothing and tells us nothing about who you are. It is what lets the app say “this tournament belongs to this device”, and it is what lets a host find their tournaments again if the phone's local data is lost.

That identifier disappears if you delete the app or move to a new phone. For that reason you can optionally connect your Apple ID under “Backup”. If you do, Apple gives us a stable user identifier and an email address — Apple lets you hide your real address and send a private relay address instead, which is entirely your choice. We use this solely to recognise that your tournaments are yours and to help you if you write to us about recovering one. We never send you email otherwise, and there is no newsletter. Everything else in the app works without connecting an Apple ID.

You can delete that account yourself, in the app, at any time: open Backup and tap Delete Account. This removes the account together with everything stored under it — every tournament you host, the results guests reported for them, and your backup list. Guests can no longer open those tournaments afterwards, and the step cannot be undone. You do not need to write to us for it.

Camera

tournament asks for camera access only when you tap “Scan QR”. The image is decoded on your device to read the tournament link out of the code. No photo or video is stored, kept or transmitted anywhere.

Nothing else leaves the app

Apart from the tournament data described above, tournament contacts no other service. The invitation QR code is drawn on your own device, and every image, sound and font ships inside the app — so nothing about your tournament or your device is handed to a third party in order to display it, and both work without a connection.

What we do not do

• No analytics, no usage statistics, no crash reporting.
• No advertising, no advertising identifiers, no ad networks.
• No tracking across apps or websites, and no data sold or handed to anyone for their own purposes.
• No cookies in the apps.

Why we may process this, and for how long

We process tournament data to provide the function you asked for — running a shared tournament (performance of a contract) — and to keep a host's own tournaments recoverable, which is what an organiser reasonably expects (legitimate interest). Connecting an Apple ID happens only on your consent, and you can stop using it at any time.

Local data stays on your device until you delete the tournament or the app. A tournament in our database stays there so it can be reopened, looked up or restored later — a league runs for months, and results people can no longer find are worse than useless. Ask us and we will delete it: write to info@boff.ch with the tournament name or its link.

Processors and transfers

• Google (Firebase Realtime Database, Firebase Authentication, Firebase Hosting for join.ochestra.ch) — stores and delivers tournament data on our behalf. The database is located in the EU.
• Apple — handles all purchases, and Sign in with Apple if you choose to use it.
• Vercel — hosts this website and keeps standard server logs.

These providers belong to international groups. Where they transfer personal data outside Switzerland or the EEA, they do so on the basis of the standard contractual clauses or an equivalent recognised safeguard.

Your rights

You can ask us for a copy of the data we hold about you, and ask us to correct it, delete it, restrict its processing or hand it over in a portable form. You can object to processing based on legitimate interests, and withdraw a consent you have given at any time with effect for the future. One email to info@boff.ch is enough — we do not require a form.

If you think we handle your data wrongly, you may complain to the Swiss Federal Data Protection and Information Commissioner (FDPIC), or — if you live in the EEA — to the supervisory authority of your country.

Children

The apps are suitable for all ages and are not directed at children in particular. We do not knowingly collect personal data from children. A tournament contains only what its host types in.

Security

Traffic between the apps and our database is encrypted in transit. Our database rules allow only the host of a tournament to change it. No system is perfect, and a tournament link is readable by whoever holds it — please keep that in mind when sharing one.

This website

ochestra.ch uses no cookies, no analytics and no tracking. It loads web fonts from Google Fonts and Fontshare, which receive the IP address of your browser in order to deliver the fonts, and it is hosted by Vercel, which keeps standard server logs (including IP address) for operation and security. The guest view at join.ochestra.ch is hosted on Firebase Hosting and behaves as described under “tournament” above.

Changes

If this policy changes, the new version is posted on this page with a new “Last updated” date.
