Privacy Policy
We believe your data belongs to you. Here is exactly how we protect it.
Last Updated: May 16, 2026
1. Introduction
Welcome to Tools Lurkawindo. We are committed to protecting your personal information and your right to privacy. Because of the nature of our tools (handling financial calculations and personal files), we have built this platform with a privacy-first mindset. This policy explains what information we collect, how we use it, and what rights you have in relation to it.
2. How We Process Your Data (Our Architecture)
Unlike traditional web applications, we do not want your data. We operate on a Hybrid Zero-Retention Architecture:
Client-Side Tools
For tools like our financial calculators, password generators, and text editors, all data is processed locally in your web browser using JavaScript. No data is sent to our servers.
Ephemeral Server Processing
For heavy tasks (like PDF merging or Image compression), files may be processed on our servers. These files are processed in temporary RAM and are permanently deleted instantly after processing. We keep zero backups.
3. Information We Do NOT Collect
- We do not require account creation.
- We do not collect names, email addresses, or phone numbers.
- We do not view, read, or analyze the contents of the files you upload.
- We do not store or log your financial inputs from our calculators.
4. Information Automatically Collected
Like almost all websites, our servers automatically collect basic, non-personally identifiable information when you visit. This information is used strictly to maintain the security and operation of our site, and for internal analytics. This includes:
- Browser and device characteristics (e.g., Chrome on Windows).
- Operating system and screen resolution.
- Referring URLs and timestamps of your visits.
- Anonymized IP addresses (used strictly to prevent DDoS attacks and abuse).
5. Cookies and Third-Party Advertising
To keep our tools 100% free, we use third-party advertising companies to serve ads when you visit our website. These companies may use cookies to serve ads based on your prior visits to our website or other websites.
Google AdSense & DoubleClick Cookie
Google, as a third-party vendor, uses cookies to serve ads on our site. Google's use of advertising cookies enables it and its partners to serve ads to our users based on their visit to our site and/or other sites on the Internet. Users may opt out of personalized advertising by visiting Google Ads Settings.
6. Browser Local Storage
To improve your experience, some of our tools (like the sidebar toggle state or calculator preferences) use your browser's Local Storage. This data is saved directly on your hard drive, not on our servers. You can clear this data at any time by clearing your browser's cache.
7. Contact Us
If you have questions or comments about this Privacy Policy, please contact us. We are always happy to clarify our security practices.
