Frequently asked, honestly answered.

What is MatchDaySync?

An independent football statistics site: fixtures, results, tables, club and league statistics and matchday guides, built from the matches we store. During the 2026 FIFA World Cup we published calibrated projections with a confidence rating on every number; that work is kept as the World Cup 2026 archive.

Is this advice on what to do?

No. We publish statistics and analytics for information only. We do not make recommendations and we do not optimise for outcomes; we optimise for calibration.

Can I still buy the World Cup 2026 products?

No. World Cup 2026 has finished, so its products are no longer on sale. Everyone who bought one keeps their files and, where it was included, the live dashboard.

How do past buyers get their files?

Payment ran through Stripe's secure checkout. Once Stripe confirmed the payment, the download links appeared on the checkout confirmation page. Opening that page's link again checks the payment with Stripe and gives fresh download links, valid for 24 hours. Lost the link? Email info@matchdaysync.com with your Stripe receipt.

What if a file is faulty?

Email info@matchdaysync.com with your receipt and tell us what is wrong. If a file is faulty or materially mis-described we will fix it or refund it.

What does a projection actually mean?

It is the model's central estimate of a statistical total for one match, with a probability around a threshold and a confidence rating attached. A 62% probability does not promise the outcome; it means roughly 62 of every 100 such matches would clear the threshold if the model is well calibrated.

What does a projection NOT mean?

It is not a guarantee, a lock, or a recommendation to act. A Low-confidence projection is a flag that the data is thin. We publish it because hiding it would be dishonest, not because we are confident in it.

What is your sample?

The 128 matches of the 2018 and 2022 FIFA World Cups. Club-league data was deliberately excluded so the calibration matches the conditions of tournament play.

How is World Cup 2026's 48-team format handled?

We say plainly that it is untested. Where the new structure (Round of 32, third-place qualification) could shift baselines we lower confidence rather than guess louder. See the methodology page for details.

Do you publish your hit rate?

Yes. The World Cup 2026 projected-versus-actual record is on the accuracy page, and the desk's verdict stories in News check each projection against the stored result, misses included.
