Privacy

Your data never leaves your browser. All calculations run entirely on your device. We don't have servers that process or store your financial data.

What we collect

Nothing about your inputs. We never see the numbers you enter into our tools — not your salary, savings, expenses, or any other financial information.

Local storage

Your tool settings are saved in your browser's localStorage so they persist when you return. This data stays on your device and is never sent to us.

Google Drive sync (optional)

If you choose to sign in with Google, your data is synced to your own Google Drive (appDataFolder). The data flows directly between your browser and your Drive account — our servers are not involved.

Analytics

We may use privacy-friendly analytics (such as Cloudflare Web Analytics) to count page views. These do not use cookies and do not track individual users. We never track what you type into our tools.

Advertising

We may show ads served by Google AdSense. Google and its partners use cookies to show ads based on your previous visits to this site or other sites. You can turn off personalized ads in Google Ad Settings, or opt out of other vendors' cookies at aboutads.info. How Google uses this data: Google advertising policies. We never pass the numbers you type into a tool to advertisers.

Third-party services

• Google Fonts — for typography (Inter font family)
• Google Identity Services — only if you opt into Drive sync
• Cloudflare — hosting and CDN
• Google AdSense — ads (see Advertising above)
