Before You Contact Us...
Many common questions are already answered below. This might help you get an instant answer:
Q: How accurate are the calculators?
Our calculations are mathematically precise based on your inputs. Default assumptions (e.g., 7-10% stock returns, 3% inflation) are conservative historical averages. See our Disclaimer for detailed methodology.
Q: Is this financial advice?
No. InvestTool provides educational calculators only. We don't recommend specific investments, and our output isn't personalized financial advice. Consult a qualified financial adviser for decisions about your portfolio.
Q: Can I save my calculations?
Yes, create a free account on InvestTool to save calculations. We don't collect your calculator inputs—saved data is stored securely in your account. See our Privacy Policy.
Q: I found a bug. Where do I report it?
Email contact@investtool.app with details about the bug (calculator name, inputs used, unexpected output, device/browser). We prioritize bug fixes.
Q: Can I suggest a new calculator or feature?
Absolutely! We love feature ideas. Email us with your suggestion, describe what you want to calculate, and explain why it would be valuable. Popular requests directly influence our roadmap.
Q: Can I use InvestTool for client meetings or in my content?
Yes! Financial advisers, journalists, educators, and content creators regularly reference InvestTool. No attribution required, though we appreciate mentions. For large-scale embedding or integration, contact us.
Q: I found a security issue. How do I report it?
Please email contact@investtool.app with details about the vulnerability. Do not post security issues publicly. We take security seriously and will respond immediately.
