Calculator inputs stay on your device
Every calculator on RunwayCalc runs entirely in your browser using client side JavaScript. When you type your salary, your monthly SIP, your loan amount, your rent or your tax deductions, those numbers are computed locally and shown back to you on the same screen. They are never transmitted to any server operated by [COMPANY_NAME] or to any third party. We do not log calculator inputs, we do not store them, and we have no way to retrieve what you entered.
If you close the tab, the inputs disappear. No account is required to use any calculator on the site.
What we do collect
We collect basic, anonymised analytics about which pages are visited, how long the page took to load, and which country a visitor came from. We use this to decide which calculator to build next and to spot performance regressions. The analytics are collected by a privacy respecting analytics provider that does not set tracking cookies and does not build cross site profiles. No personal identifier is stored alongside the analytics event.
Server logs may contain your IP address for a short retention window, used only for security and abuse prevention. These logs are rotated within thirty days.
What we do not collect
We do not collect names, email addresses, phone numbers, PAN, Aadhaar, or any other personal identifier on any calculator page. We do not run advertising trackers, cross site cookies, fingerprinting scripts or third party data brokers. We do not sell, rent or share visitor data with any party for any purpose.
If you choose to write to us at [CONTACT_EMAIL], we will see your email address. We use it only to reply, and we do not add it to any marketing list.
Cookies
RunwayCalc sets at most one cookie, used to remember your light or dark mode preference between visits. The cookie is first party, contains only the value 'light' or 'dark', and expires after one year. You can clear it from your browser settings at any time without affecting any calculator.
We do not use cookies for advertising, retargeting or tracking.
Third party services
The site uses fonts hosted by Google Fonts. By loading a font, your browser establishes a connection to Google's font CDN, which may log the request. We have no control over those logs. If you prefer to avoid this, browser extensions that block external font loading work without breaking the site.
Charts are rendered using Chart.js, which runs entirely in your browser without contacting any external server.
Data security
We follow standard web security practices. The site is served over HTTPS, dependencies are kept current, and the smallest possible surface is exposed to the internet. Because we do not store calculator inputs or personal data, the practical impact of a breach is small.
Children
RunwayCalc is intended for users above the age of eighteen. We do not knowingly collect any data from children. If you believe a child has provided personal information through our contact email, write to [CONTACT_EMAIL] and we will delete it promptly.
Changes to this policy
If we make material changes to this Privacy Policy, the updated version will be published on this page with a revised last updated date. Continued use of the site after a change indicates acceptance of the updated terms. If a change affects how we collect or use data, we will note that at the top of this page.
Contact
Questions about privacy can be sent to [CONTACT_EMAIL]. For requests under the Digital Personal Data Protection Act, 2023 or any other applicable law, the same address reaches the [COMPANY_NAME] data protection contact, who will respond within the legally mandated window.
