ToolStack and any health-related calculations are provided for informational and educational purposes only. Results including BMI, body fat estimates, calorie needs, and ideal weight ranges are general estimates based on established formulas and population averages. They do not account for individual health conditions, medications, or circumstances. Always consult a qualified healthcare professional before making changes to your diet, exercise, or healthcare plan.
ToolStack and any investment or financial calculations are provided for informational and educational purposes only. Compound interest projections assume a fixed rate of return and do not account for investment risk, market volatility, fees, taxes, or inflation (unless toggled). Past performance of any investment does not guarantee future results. Nothing on ToolStack constitutes financial advice. Consult a qualified financial advisor before making investment decisions.
While we strive to ensure the accuracy of all calculations and conversions, ToolStack makes no warranty that the results produced by its tools are accurate, complete, or suitable for any specific purpose. Users are responsible for verifying results for any critical application.
To the fullest extent permitted by applicable law, ToolStack and its owners, employees, and affiliates shall not be liable for any indirect, incidental, special, consequential, or punitive damages — including but not limited to loss of profits, data, or goodwill — arising from:
In no event shall ToolStack's total liability to you exceed the greater of (a) the amount you paid to access the Service in the past 12 months, or (b) $0.00 USD, since the Service is provided free of charge.

You may not reproduce, copy, or resell the ToolStack brand or website design without explicit written permission.
The outputs you create using our tools — including PDF invoices, QR codes, and downloaded files — are entirely yours. ToolStack claims no intellectual property rights over content you generate.
Some tools use open-source libraries (jsPDF, Chart.js, QRCode.js, etc.) distributed under their respective open-source licences. Use of these libraries complies with their terms.

We do not control the content of third-party advertisements. We are not responsible for the products, services, or content advertised by third parties. Advertisements do not represent an endorsement by ToolStack.
We do not allow advertisers to pay for preferred placement in tool results or for Claude to promote specific products within tool outputs. Our tools produce objective results based solely on the inputs provided.
We reserve the right to modify, suspend, or discontinue any tool or the entire Service at any time, with or without notice, for any reason including maintenance, upgrades, or business decisions.
We do not guarantee that the Service will be available at all times. Downtime may occur due to maintenance, technical issues, or circumstances beyond our control.

We strongly advise you to read the terms and privacy policy of any third-party site you visit. ToolStack's inclusion of a link does not imply endorsement of the linked site.
These Terms shall be governed by and construed in accordance with applicable law. Any disputes arising from these Terms or your use of the Service shall be subject to the exclusive jurisdiction of the relevant courts in the jurisdiction where ToolStack is operated.
If any provision of these Terms is found to be unenforceable or invalid, that provision will be limited or eliminated to the minimum extent necessary so that the remaining Terms will otherwise remain in full force and effect.
We reserve the right to modify these Terms at any time. When changes are made, we will update the "Last updated" date at the top of this page. Significant changes will be noted on the homepage.
