Privacy Policy

Summary and Core Principles

Renditra is built with privacy-first engineering. We do not require user accounts, passwords, or email registrations to access any financial calculators. All inputs entered into our forms are processed exclusively on your client device using local JavaScript. Your financial data is never transmitted to, logged by, or retained on our servers.

Our revenue model relies on third-party digital advertising (Google AdSense) and anonymous aggregate site performance metrics (Cloudflare Web Analytics). Details regarding these services and applicable US consumer rights are explained below.

Data Controller and Site Operator

Renditra is operated by Meryem Bilge Seyhun as an independent sole proprietorship. Official correspondence may be sent to info@renditra.com.

Physical address: Muratçeşme Mahallesi, Yunus Emre Caddesi No: 2, Büyükçekmece / İstanbul, Türkiye.

Zero-Storage Calculator Architecture

Salary figures, investment amounts, rental values, and portfolio projections entered into any Renditra calculator run entirely within your local web browser session. No form inputs are transmitted over the network or saved in server-side databases. Closing or refreshing your browser tab permanently purges all entered session data.

Infrastructure and Security Logs

Renditra is delivered via Cloudflare content delivery network. Standard technical connection metadata, including IP addresses, browser headers, referring URLs, and access timestamps, are processed strictly for DDoS mitigation, bot defense, and secure routing.

Web Analytics

We utilize Cloudflare Web Analytics to assess overall traffic volume, geographic distribution, and page load performance. This system functions entirely without client-side cookies, does not collect personal identifiers, does not construct persistent user tracking profiles, and is completely isolated from advertising networks.

Third-Party Advertising and Google AdSense

This website displays third-party advertisements served by Google AdSense. Google and affiliated advertising partners utilize cookies, web beacons, and related tracking technologies to serve ads based on prior visits to this website or other web destinations.

Google's use of advertising cookies enables it and its partners to serve relevant ads to users based on browsing patterns. You may opt out of personalized advertising by visiting Google Ads Settings at https://adssettings.google.com. You may also opt out of third-party vendor cookies for personalized advertising by visiting http://www.aboutads.info/choices/.

State Consumer Privacy Rights (CCPA / CPRA)

If you are a resident of California or another US state with comprehensive consumer data privacy statutes (such as Virginia, Colorado, Connecticut, or Utah), you possess specific statutory rights regarding personal data. We do not sell personal financial data or consumer information to third parties.

To submit an inquiry or exercise applicable consumer rights, you may contact info@renditra.com.
