Datenschutzrichtlinie

Last updated: January 2026

1. Overview and Commitment

Picotometer.com ("we," "our," "us," "the Site") is committed to protecting your privacy. This Privacy Policy explains what information we collect, how we use it, how we protect it, and your rights regarding your personal data. By using the Site, you consent to the data practices described in this policy. We designed Picotometer.com with privacy as a core principle: our conversion tools run entirely in your browser, and we never collect, transmit, or store the values you enter into our calculators.

2. Information We Collect

Conversion tool inputs: Values you enter into our conversion calculators are processed entirely by client-side JavaScript running in your web browser. These values are never transmitted to our servers, never stored in any database, and never logged in any system. Your conversion calculations are completely private and ephemeral — they exist only in your browser's memory while you are actively using the tool.

Automatically collected technical data: When you visit the Site, our web servers and hosting infrastructure may automatically collect standard technical information including: your IP address (which may be anonymized or truncated by our hosting provider), browser type and version, operating system, referring URL (the page that linked you to our site), pages viewed on our site and time spent on each page, approximate geographic location derived from IP address (country/region level only), and timestamps of your visit. This information is used solely for site analytics, security monitoring, performance optimization, and understanding aggregate usage patterns.

Contact form submissions: If you contact us through our contact form, we collect the information you voluntarily provide, which may include your name, email address, and message content. This information is used exclusively to respond to your inquiry and is not shared with third parties, used for marketing, or added to any mailing list without your explicit consent.

3. How We Use Collected Information

We use automatically collected technical data to: analyze aggregate traffic patterns and usage statistics to improve our content and tools; monitor for security threats, abuse, and unauthorized access; optimize site performance, load times, and user experience; understand which conversion tools and educational pages are most valuable to our users; and ensure technical compatibility across different browsers and devices.

We use contact form submissions exclusively to: respond to your specific inquiry, question, or feedback; investigate and resolve accuracy concerns or bug reports you have submitted; and communicate with you about partnership or collaboration proposals you have initiated.

4. Information We Do NOT Collect

We want to be explicit about the data we do not collect: we do not collect conversion inputs or results; we do not require or collect user accounts, usernames, or passwords; we do not collect payment information (all tools are free); we do not collect demographic information such as age, gender, or income; we do not build user profiles for behavioral targeting; we do not track individual users across sessions for advertising purposes; and we do not sell, rent, or trade any user data to third parties for any purpose.

5. Cookies and Tracking Technologies

The Site may use cookies and similar technologies for the following limited purposes:

You can control all cookie settings through your browser preferences. Most browsers allow you to block all cookies, block only third-party cookies, or clear existing cookies. Disabling cookies will not affect the functionality of our conversion tools, which operate independently of cookie technology.

6. Third-Party Services

We may use the following categories of third-party services: web hosting providers that serve our static files; content delivery networks (CDNs) that accelerate page load times globally; analytics services that help us understand aggregate usage patterns; and advertising networks that may display ads on our pages. These third-party services have their own privacy policies governing their data practices. We encourage you to review those policies independently.

7. Data Security

We implement industry-standard security measures to protect against unauthorized access, alteration, disclosure, or destruction of data. These measures include: serving all pages over HTTPS with TLS encryption; using a static site architecture that eliminates server-side attack vectors such as SQL injection, XSS from server rendering, and session hijacking; restricting administrative access to authorized personnel only; and regularly reviewing our security practices and infrastructure.

However, no method of electronic transmission or storage is completely secure. While we strive to protect your data using commercially reasonable means, we cannot guarantee absolute security. We encourage you to exercise caution when sharing personal information online.

8. Data Retention

Server log data (IP addresses, page views) is retained for a maximum of 90 days for security and analytics purposes, after which it is automatically deleted or anonymized. Contact form submissions are retained for as long as necessary to resolve the inquiry, after which they are archived or deleted. We do not maintain long-term databases of user activity or personal information.

9. Children's Privacy

The Site is intended for general audiences of all ages and provides educational scientific content suitable for students. We do not knowingly collect personal information from children under 13 years of age. If we become aware that we have inadvertently collected personal information from a child under 13, we will take immediate steps to delete that information. If you are a parent or guardian and believe your child has provided personal information to us, please contact us immediately.

10. Your Rights Under GDPR, CCPA, and Other Privacy Laws

Depending on your jurisdiction, you may have the following rights regarding your personal data: the right to know what personal data we hold about you; the right to request correction of inaccurate data; the right to request deletion of your personal data; the right to data portability (receiving your data in a machine-readable format); the right to object to certain types of data processing; the right to withdraw consent at any time; and the right to file a complaint with your local data protection authority.

To exercise any of these rights, please contact us through our contact page or email hello@picotometer.com. We will respond to legitimate requests within 30 days, as required by applicable law.

11. International Data Transfers

The Site is hosted in the United States. If you access the Site from outside the United States, please be aware that your technical data (IP address, browser information) may be transferred to and processed in the United States. By using the Site, you consent to this transfer. We take reasonable measures to ensure that any transferred data is treated securely and in accordance with this Privacy Policy.

12. Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in our practices, technologies, legal requirements, or other factors. Changes will be posted on this page with an updated "Last updated" date. Material changes will be highlighted with a notice on our homepage. Your continued use of the Site after changes are posted constitutes your acceptance of the revised policy.
