Do You Store My Data?

No, We Don't Store Your Data

Every calculation happens entirely in your web browser. When you enter stock prices, share counts, or any other information, that data never leaves your computer. Nothing gets sent to our servers. Nothing gets saved to databases. Your investment information remains completely private.

This design choice prioritizes your privacy. Many websites collect user data for various purposes. We deliberately built our calculators to avoid that entirely. You can calculate profits, returns, and projections with complete confidence that your financial information stays yours alone.

How Browser-Based Calculations Work

Modern web browsers can run complex calculations without needing external servers. Our calculators use JavaScript code that executes on your device. Type in your numbers and the browser does the math instantly using its own processing power.

This approach offers several advantages beyond privacy. Calculations happen faster since no data travels across the internet. The tools work even if your internet connection drops after loading the page. You get immediate results without any network delays.

What Data We Actually Collect

While we don't collect your calculator inputs, we do use basic analytics to improve the site. This includes:

• Which pages you visit
• How long you spend on the site
• Which calculators get used most often
• General location information (country/city level, not precise location)
• Device type and browser used

This anonymous usage data helps us understand which tools matter most to users. We can prioritize improvements based on actual usage patterns. But again, we never see the actual numbers you enter into calculators.

No Accounts Required

We don't offer user accounts or logins. This eliminates a major source of potential data exposure. No passwords to manage, no profile information to protect, no account history to secure. You can use every calculator freely without providing any personal information whatsoever.

Many financial sites require registration to access tools. We believe investment calculations should be freely available to everyone without barriers. The lack of accounts also means you cannot accidentally leave sensitive data on our servers because we simply have no way to store it.

Browser Local Storage

Some calculators might use your browser's local storage to remember your preferences or recent calculations. This data stays entirely on your device. We cannot access it. Other websites cannot access it. Only that specific calculator on your browser can read it.

You can clear this data anytime through your browser settings. Clearing your browser cache or local storage removes any saved calculator information. This gives you complete control over what gets remembered.

Third-Party Services

We use standard web analytics services to track site usage. These services may set cookies in your browser to distinguish unique visitors. However, they only see aggregated behavior patterns, not your specific calculator inputs.

For example, analytics might show that 1,000 people used the CAGR calculator today. But the analytics system never knows whether you calculated a 5% return or a 15% return. That data exists only in your browser temporarily.

HTTPS Encryption

Our website uses HTTPS encryption for all connections. This prevents anyone from intercepting your browser traffic and seeing what pages you visit. While your calculator inputs don't leave your device anyway, HTTPS adds an extra layer of security for your overall browsing session.

Comparing to Other Tools

Some investment calculator websites require you to create accounts and store your portfolio data on their servers. These services might offer convenience like saving multiple calculations or syncing across devices. However, they also create privacy risks.

Our approach sacrifices those convenience features to maximize privacy. You need to re-enter values each time you use a calculator. But you gain absolute assurance that your investment positions, profit amounts, and trading strategies never exist anywhere except your own computer.

Exporting and Saving Results

If you want to save calculator results, you can take screenshots or copy the numbers into your own spreadsheet. Some browsers let you save web pages for offline viewing. These options give you control over what gets saved and where.

We don't provide built-in export features because that would require processing your data, even temporarily. Keeping everything in your browser maintains the privacy guarantee we promise.

Privacy Policy Details

For complete information about how we handle data and protect privacy, read our Privacy Policy. It covers all aspects of data collection, use, and protection in detail.

We update the privacy policy if our practices change. The current version always reflects our actual data handling procedures accurately.
