Privacy Policy

Movies Calculator (https://moviescalculator.com) is operated by Sergei Chyrkov. This Privacy Policy explains what information is collected when you use the site, how it is used, and the choices you have.

The site is an informational tool for estimating movie watch time. We do not require an account, sell subscriptions, or process payments.

We collect limited information automatically when you visit the site, and you may optionally share calculator settings through the URL.

• Usage and analytics data — page views, approximate location (country/region), device type, browser, referrer, and interactions such as calculator events or link clicks, collected through analytics tools described below.
• Server and hosting logs — IP address, request time, pages requested, and user agent, retained by our hosting provider for security, performance, and troubleshooting.
• Calculator inputs in the URL — when you adjust the calculator or use Share, your settings may appear in the page URL (for example daily hours, playback speed, or time horizon). Anyone with that link can see those settings; we do not store them in a user profile.

We do not intentionally collect:

• Names, email addresses, or postal addresses (unless you contact us voluntarily)
• Payment or billing information
• Government ID numbers
• Precise geolocation from your device
• Contents of private messages or files on your device

We and our analytics providers use cookies, local storage, pixels, and similar technologies to measure traffic and understand how the site is used.

You can control cookies through your browser settings. Blocking cookies may affect some site features. Where required by law, analytics may only run after you consent through your browser or applicable consent tools configured in our tag manager.

We use trusted third parties to operate and measure the site. They process data according to their own privacy policies:

• Google Analytics and Google Tag Manager (Google LLC) — website analytics and event measurement
• Ahrefs Analytics — traffic and SEO measurement
• Vercel Speed Insights (Vercel Inc.) — performance monitoring
• The Movie Database (TMDB) — movie metadata and poster images served to your browser
• JustWatch — streaming availability data referenced on some pages
• Product Hunt — optional promotional badge linking to an external page

We use collected information to:

• Operate, maintain, and improve Movies Calculator
• Understand which pages and features are useful
• Monitor performance, security, and abuse
• Respond to questions or feedback you send us

We do not sell your personal information. We do not use your data for cross-context behavioral advertising.

Analytics providers retain data according to their default retention settings (often 2–14 months for event-level data unless configured otherwise). Hosting logs are retained for a limited period needed for security and operations, then deleted or aggregated.

If you contact us directly, we keep correspondence only as long as needed to respond and maintain a record of the inquiry.

Depending on where you live, you may have rights to access, correct, delete, or restrict certain processing of your personal information, or to opt out of certain analytics or targeted advertising.

You can also use browser Do Not Track or global privacy control signals where supported; we honor applicable legal opt-out requirements.

To exercise your rights or ask a privacy question, contact Sergei Chyrkov via the contact link on our About page or on X (@SergeiChyrkov). We will respond within a reasonable time.

Movies Calculator is not directed at children under 13, and we do not knowingly collect personal information from children. If you believe a child has provided us information, please contact us and we will delete it.

The site is primarily intended for visitors in the United States. If you access the site from other regions, your information may be processed in the United States or other countries where our service providers operate, which may have different data protection laws than your home country.

We use reasonable technical and organizational measures to protect information processed through the site. No method of transmission over the Internet is 100% secure, and we cannot guarantee absolute security.

We may update this Privacy Policy from time to time. The "Last updated" date at the top reflects the latest revision. Material changes will be posted on this page. Continued use of the site after changes means you accept the updated policy.
