1. Fundamental Architecture: 100% In-Browser Calculations
Zetawala Money is deliberately engineered as a purely static, client-side web utility. When you use our calculators:
- Bank Account Numbers & IBANs: The characters you enter into the IBAN validator or BLZ tool are verified locally in your browser’s memory using the ISO 13616 modulo-97 algorithm. They are never sent across the internet, logged in access files, or transmitted to any remote database.
- Salaries, Taxable Income & Deductions: All salary, tax, and social contribution formulas execute strictly within your device’s JavaScript engine.
- Travel Dates & Schengen Stays: Stays entered into the Schengen calculator remain on your device.
2. Use of LocalStorage on Your Device
Certain tools (such as the Schengen 90/180 calculator) offer the convenience of saving your trip history so you do not have to re-type it upon your next visit.
This information is stored exclusively in your browser’s HTML5 localStorage container. It remains exclusively on your own personal device, is never transmitted to our servers or third parties, and can be cleared at any time by clearing your browser cache or clicking the tool’s reset button.
3. Display Advertising & Google AdSense Compliance
To keep our tools completely free without paywalls or subscriptions, Zetawala Money displays digital advertising served by Google AdSense and its certified advertising partners.
- Third-party vendors, including Google, use cookies to serve ads based on a user’s prior visits to this website or other websites across the internet.
- Google’s use of advertising cookies enables it and its partners to serve ads to users based on their visits to our site and/or other sites on the Internet.
- Consent Management (EEA, UK, Switzerland): For visitors located in the European Economic Area (EEA), the United Kingdom, and Switzerland, personalised advertising is only served if you explicitly give your informed consent via Google’s certified Consent Management Platform (CMP). If you decline or choose non-personalised ads, cookies will only be used for frequency capping, aggregated ad reporting, and fraud prevention.
- Opt-Out: Users may opt out of personalised advertising at any time by visiting Google Ads Settings (https://adssettings.google.com).

4. Cookieless Web Analytics (Cloudflare)
We use Cloudflare Web Analytics to monitor aggregate traffic trends, page views, and performance metrics across the globe.
Unlike traditional tracking platforms, Cloudflare Web Analytics is 100% cookieless. It does not use any tracking pixels, does not collect personal identifiers or IP addresses, and does not follow users across third-party websites. It is engineered specifically to preserve complete visitor anonymity.
