Privacy Policy — Calcify’s Zero-Upload, Client-Side Data Protection Standard

1. Core Privacy Principle: Privacy by Architecture, Not Just Policy

At Calcify ("we", "our", or "the Platform"), we believe that your personal finances, salary structure, tax liabilities, business profit margins, medical metrics, and bank statements are strictly your private business. Unlike conventional online financial portals that require mandatory account registration, phone number verification, or server-side form submissions just to view an EMI schedule or income tax projection, Calcify is engineered on a "Zero-Upload, 100% Client-Side Execution" architecture.

This Privacy Policy explains in clear, unambiguous language what information is processed when you use Calcify, how your browser executes calculations locally, how optional browser storage (localStorage) operates on your device, and your rights under global data protection frameworks including the General Data Protection Regulation (GDPR), the California Consumer Privacy Act (CCPA), and the Digital Personal Data Protection Act (DPDP Act).

2. Zero Server Transmission of Calculation Inputs & Financial Data

When you enter numbers, dates, or text into any of the 188 calculators on Calcify, all mathematical computations are executed exclusively by JavaScript running inside your own device’s web browser memory (RAM). Your calculation inputs and computed results are never transmitted to, stored on, or analyzed by Calcify servers or any third-party cloud database.

This guarantee applies with equal force to our specialized tools and export workflows:

• Local CSV Bank Statement Analyzer: When you upload a CSV bank statement file in Category 02 (#019 Bank Statement Analyzer), the file is parsed directly inside your browser using the HTML5 FileReader API. Neither the CSV file nor any transaction row, account balance, or merchant description is ever uploaded over the internet.
• Customer-Branded Report Exports (PDF, PNG, CSV): When you use the "Export with My Branding" feature and upload your company logo (JPG, PNG, or SVG) alongside your company name, address, phone number, email, and website, the PDF (via client-side jsPDF), PNG (via HTML5 Canvas), and CSV files are synthesized entirely on your device.
• Session Calculation History: The comparison log displayed on individual calculator pages is held temporarily in your browser tab’s volatile memory so you can compare multiple scenarios side by side. Closing or refreshing the tab clears this volatile session log.

3. How Calcify Uses Browser LocalStorage (No Tracking Cookies)

To provide a seamless, personalized user experience without forcing you to create a user account or log in with an email address, Calcify utilizes your web browser’s native localStorage mechanism. Data saved in localStorage resides strictly on your physical device and is never sent to a remote server in HTTP headers.

Specifically, Calcify uses the following transparent localStorage keys:

• calcify_favorites / calculator_hub_favorites: Stores the array of calculator IDs that you have bookmarked using the Heart icon so your Favorite Calculators appear at the top of the homepage on future visits.
• calcify_theme / calculator_hub_theme: Remembers whether you prefer Light Mode or Dark Mode.
• calcify_currency / calculator_hub_currency: Saves your preferred currency code (such as INR, USD, EUR, GBP, AED, CAD, AUD, SGD, JPY, SAR, CHF, or CNY) across calculator pages.
• calcify_branding / calculator_hub_branding: If and only if you check the "Remember my company branding details in this browser" box inside the Branded Export modal, your company name, contact details, brand color, and base64 logo are stored locally in your browser so you do not have to re-type them for every client report.

4. Voluntary Contact Information & Third-Party Links

The only circumstance in which you may voluntarily provide personal contact information (such as your name and email address) is when you submit an inquiry through our Contact Us page or send an email to our support desk. Any information submitted via a support inquiry is used solely to respond to your question or resolve your technical report and is never sold, rented, or shared with advertisers or data brokers.

You retain complete control over your browser data at all times. You may clear your saved Favorites, remove your saved company logo inside the Branded Export modal, or clear your browser’s site data at any time with a single click.
