Frequently Asked Questions
Is my data safe?
Yes. Your file is processed entirely in your browser — it never leaves your device. We do not upload, store or see your data at any point.
What file types work?
CSV (.csv) and Excel (.xlsx, .xls) files. If you have a different format, open it in Excel or Google Sheets and save as CSV first.
My file has a date like "4536" — is that a problem?
That is an Excel serial date format. The Solver automatically detects and converts these to readable month/year labels.
What's the difference between free and Pro?
The free plan gives you instant charts, insights and 3 AI-powered chat questions per session. Pro gives you unlimited AI questions, PDF export, saved dashboards and anomaly alerts — for A$19/month.
Does it work on mobile?
Yes. The Solver is fully mobile-responsive. All charts, filters and AI chat work on iPhone and Android.
How many rows can I upload?
The Solver handles files up to 50,000+ rows without issue. For very large files, processing may take a few seconds.
Can I cancel my Pro subscription?
Yes, cancel anytime. There are no lock-in contracts. Your free access continues even after cancelling Pro.
Privacy Policy

1. Your data stays on your device
Files you upload are processed entirely within your browser using client-side JavaScript. Your spreadsheet data is never transmitted to our servers, never stored in any database, and never seen by us. When you close the tab, the data is gone.
2. Email address
When you enter your email address to unlock the dashboard, it is saved to your browser's local storage and also sent to our email list provider (Formspree). We use this address to send you product updates and new feature announcements. We do not sell or share your email address with third parties. You can unsubscribe at any time.
3. AI chat questions
When you ask a question in the AI chat, a summary of your data (not your raw file) and your question are sent to the Anthropic API to generate a response. This summary contains aggregated statistics only — not individual rows. Please review Anthropic's privacy policy at anthropic.com for how they handle API data.
4. Cookies and analytics
We use browser localStorage to remember your preferences (currency, email, usage count). We do not use third-party tracking cookies or advertising pixels. We may use basic analytics to understand how many people visit the site.
5. Children's privacy
The Solver is not directed at children under 13. We do not knowingly collect information from children.
6. Changes to this policy
We may update this policy from time to time. The latest version will always be available at thesolver.pro. Continued use of the service constitutes acceptance of any changes.

Revenue Forecast
Next 3 periodsSolid line = actual. Dotted = projected. Shaded = confidence range.
Revenue Waterfall
Revenue minus cost equals profit. Each bar shows where money is going.
Volume vs Margin Matrix
Stars = top rightEach bubble = a category. Right = more revenue. Up = better margin. Bigger = more volume.
Growth Rate Heatmap
Green = growing vs prior period. Red = declining. Shows which categories are accelerating and which are fading across all periods.
Cumulative Revenue
Running total building over time — great for showing momentum to a board or investor.
Pareto Analysis
Bars show value per category. The orange line shows cumulative % — where it crosses 80% is your focus zone.
Value Distribution
Shows how your values are spread. Narrow peak = consistent. Two peaks = two distinct customer types.

🤖 AI cross-file insight
"Your Enterprise segment drives 67% of revenue but only represents 23% of customer count — protect these accounts aggressively. The 3 churn-risk accounts in WA share a pattern: no upsell in 90+ days and declining usage. Reach out this week before they churn. Meanwhile, VIC Mid-Market shows the highest conversion rate for upsells — prioritise that segment for Q2 expansion."
