Privacy Policy — Your Data Never Leaves Your Browser
Your privacy is not just a policy at ZMPL Tools — it is a technical reality. Every tool on this site processes your data entirely within your browser. We are not just saying we don't collect your data; we are architecturally incapable of reading what you enter into any of our tools.
What "Privacy-First" Actually Means Here
Many free online tools in India — including major GST calculators, and financial tools — log your inputs for analytics, advertising profiling, or product improvement. ZMPL Tools is built differently. All computation happens in your browser using JavaScript. Our servers serve the page and nothing else.
How Each Tool Handles Your Data
Our income tax calculator and Our GST calculator, EMI calculator, percentage calculator, and age calculator perform all arithmetic in your browser using JavaScript — no figures are sent to or stored on our servers. Unlike many free online tools in India that log your inputs for analytics or advertising, ZMPL Tools is technically incapable of reading what you enter into any tool.
Income tax calculations are performed entirely in JavaScript. No financial information is sent to any server.
CGST, SGST, and IGST figures are calculated using JavaScript arithmetic. No financial data is logged or transmitted.
The RBI EMI formula runs entirely client-side. Your loan amount, interest rate, and repayment figures are never sent to us.
All percentage calculations run in your browser. No inputs or outputs are recorded.
Your date of birth is used only for local arithmetic and is never sent to our servers or stored anywhere.
Information We Collect
ZMPL Tools does not require users to create accounts or provide personal information to use any tool. The only personal information we ever receive is what you voluntarily submit through the contact form — your name, email address, and message. This is used solely to respond to your inquiry.
We do not collect: IP addresses tied to tool usage, text or numbers entered into any tool, dates of birth entered into the age calculator, financial figures entered into the GST or EMI calculator, or any behavioural data about how you use individual tools.
Tool Usage and Content
Text, numbers, dates, or any other content entered into ZMPL Tools is processed locally on your device using browser-based JavaScript. We do not store, log, transmit, or review the content you use in our tools — not even in anonymised form. You can verify this by opening your browser's network inspector (F12 → Network) while using any tool and observing that no data requests are made to our servers during tool operation.
Contact Form Information
If you contact us through our contact page, we collect only the information you voluntarily provide: your name, email address, and message. This information is used solely to respond to your inquiry and is not shared, sold, or used for marketing purposes. Contact data is retained only for as long as necessary to resolve your inquiry.
Cookies and Analytics
ZMPL Tools may use limited, privacy-respecting analytics to understand general website usage patterns — such as which pages are visited and from which country — to improve the site. These analytics use aggregate, anonymous data only and do not track personal content entered into any tool. We do not use advertising cookies, behavioural tracking pixels, or third-party retargeting scripts.
Third-Party Services
We use an email delivery provider to send responses to contact form submissions. This provider receives only the information you submitted in the contact form (name, email, message) and is contractually prohibited from using it for any purpose beyond message delivery. We do not embed third-party advertising networks, social media trackers, or data brokers on this site.
Data Security
Because our tools process all data client-side, the primary security responsibility lies with your own device and browser. We take reasonable measures to secure our website infrastructure and contact form submissions. However, no method of internet transmission is completely secure, and we cannot guarantee absolute security of data submitted through the contact form.
Children's Information
ZMPL Tools does not knowingly collect personal information from children under the age of 13. Since no account or personal information is required to use any tool, children can use our income tax calculator, age calculator, or percentage calculator without providing any personal data. If you believe a child has submitted personal information through our contact form, please contact us and we will remove it promptly.
Consent
By using ZMPL Tools, you consent to this Privacy Policy and agree to its terms. Since our tools require no account creation and collect no personal data during tool use, your continued use of the tools represents acknowledgement of this policy.
Updates to This Policy
This Privacy Policy may be updated to reflect changes in our practices, new tools added to the site, or changes in applicable Indian data protection regulations. Any changes will be posted on this page with an updated "Last Updated" date and are effective immediately upon posting. We encourage you to review this page periodically.
