No. This site is not a betting intermediary, does not sell odds and is never a party to money transfers. It is a data-driven match analysis tool — the percentages are the result of a statistical calculation. Any betting decision is entirely the user's responsibility.

7 competitions: Premier League, La Liga, Serie A, Bundesliga, Ligue 1, the Süper Lig and the Champions League. The Turkish Cup is currently off because of a data-provider issue.

On the free plan, 5 probabilities: match result, 3 or more goals, both teams to score, which team doesn't lose and a goal in the first half. On Plus and Pro, 13 in total: in addition to the above, handicap result, half-time / full-time, correct score, total-goals range, 2+ first-half goals and first-half result.

In the spirit of transparency we show every number on the past results page (Turkish). For the match result in the Premier League our error score (Brier score) is about 0.62; the lower, the better. For comparison: saying 33% for every result scores 0.667, and writing down the league's historical average scores about 0.66. We also state openly where we cannot beat that simple average on some probabilities — no calculation is 100%.

There is no native app yet, but the site works fully in a mobile browser (responsive). Adding it to your home screen (PWA) will follow after launch.

Plus — all 13 probabilities + form/fatigue + probability-ranked pick lists + weekly picks + starting XI and formation.
Pro — on top of Plus, an AI match summary, expected goals, a comparison with betting odds, and browser notifications for matches you follow (email notifications coming soon).
All Plus and Pro features are free during the launch — no card needed. The prices shown (₺129 / ₺249) will apply once payments open. Details: Plans.

The features are already open — during the launch everyone has Plus/Pro-level access and you don't need to do anything. The end date of the free period is not set yet. We don't ask for a card: when the free period ends your account continues on the Free plan, and nothing is charged automatically. We are setting up payments (iyzico); if you want us to email you when paid subscriptions start, you can sign up on the Plans page.

Paid subscriptions are not open yet, so there is no payment to cancel right now. Once they open, cancelling is done on the Account page: the next period is not renewed and your membership stays active until the end of the current period.

Plus:
• All 13 probabilities (handicap result, half-time / full-time, correct score …)
• Scoreline probability map + team profile
• Fatigue + fixture-congestion analysis
• Probability-ranked pick lists (3 groups)
• Starting XI + formation (last match; official XI once announced)
• Weekly featured picks (top 5 across all leagues)

Pro (on top of Plus):

• Season-average expected goals + comparison board
• Comparison of betting odds with the model's probability
• Notifications for followed matches (browser; email coming soon)

Plus/Pro are free right now — paid purchase is not open and nobody has paid. Once paid subscriptions open, payments are not refunded after purchase, but membership stays active until the end of the period.

In Turkey, credit and debit cards (Visa, Mastercard, Troy) through iyzico. The payment step is verified with 3D Secure. International card support (Stripe) will be added later.

Your card details are not stored on +90 servers. Payment is processed by iyzico, a PCI-DSS-compliant payment institution; we only keep your subscription status. For recurring charges the card is held at iyzico as a secure token.

Yes. All displayed prices (Plus ₺129, Pro ₺249) are VAT included and in Turkish lira (₺). After payment a legal invoice for your subscription is issued and emailed to you.

Once the payment is confirmed your membership appears on your account within a few seconds (when the payment provider's notice is processed). If it is ever delayed, refresh the Account page; if the problem continues, contact support.

Your membership is not opened and you are not charged. If the card authorisation is declined (limit, 3D Secure cancelled, etc.) you can retry the payment step. If your trial is still running, your access is not affected.

• Top-5 European league results: football-data.org
• Shot and expected-goals data for the 5 big European leagues: Understat
• Süper Lig results, goals, cards, line-ups and referees: our own archive compiled from publicly available match data (updated within minutes after a match ends)
• Match context (injuries, news): AI scanning current news on the internet (Pro only)

In short: from how many chances each team created and conceded recently and how many goals they scored, we work out attack and defence strength (in the Süper Lig from goals only, in the Champions League from a cross-league strength rating). From these we find how many goals each side is expected to score in that match, and from that the probability of every scoreline from 0-0 to 6-6. All 13 probabilities come from these scoreline probabilities, so they never contradict each other. Past meetings and form are not part of the calculation; they are shown as information. The weekly track record covers match result, 3+ goals and both teams to score. Detailed explanation.

The AI gathers news close to match day (injuries, motivation, derby atmosphere) from the internet and reads it together with our percentages to produce an organised summary: the factors that will decide the match, tactics, possible scenarios, uncertainties. Unlike asking an ordinary chatbot, it has the percentages we calculated and writes under the same headings for every match.

The probability that a shot becomes a goal. For example, a shot worth 0.30 means that of 10 similar shots, 3 are goals. The sum over all of a team's shots shows how many clear chances it created — and depends less on luck than the score does. For the 5 big European leagues we take this data from Understat; each team's per-match average is on the match page (Pro). For the Champions League there is no free source, so we work from goals only.
