Privacy Policy

Last updated: June 2026

Introduction

SubTools ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we handle information when you use our website and subtitle tools at subtools.cc (the "Service"). By using the Service, you agree to the practices described in this policy.

We take a privacy-first approach to everything we build. Our core principle is simple: your subtitle files are your property, and we should never have access to them.

Data Processing — How Subtitle Files Are Handled

All subtitle processing happens entirely in your browser using client-side JavaScript. When you use our subtitle tools — whether converting formats, fixing timing, removing sound effects, or translating subtitles — your files are processed locally on your device. We do not upload, transmit, store, or have any access to your subtitle files or their content.

This architecture is fundamental to our service. Unlike other online tools that send your files to remote servers for processing, SubTools keeps everything on your computer. Your subtitles, transcripts, and any other content you process through our tools remain private and under your control at all times.

Information We Collect

We collect minimal information to operate and improve our service:

Automatically Collected Information

• Usage Analytics: We use Google Analytics 4 (GA4) to collect anonymous usage data, including page views, tool usage patterns, and general geographic information (country level only). This helps us understand which tools are most useful and how users navigate the site.
• Device Information: Browser type, operating system, screen resolution, and device type — collected anonymously to ensure our tools work correctly across different platforms.
• Referral Information: How you arrived at our site (search engine, direct visit, referral link) — used to understand our traffic sources.

Information You Provide

• Contact Form Messages: When you send us a message through our contact form, we receive your name, email address, and message. We use this information solely to respond to your inquiry.
• Tool Settings: Parameters you enter in tools (such as delay values, FPS settings, or search terms) are processed locally and are not transmitted to our servers.

Cookies

We use the following types of cookies:

• Essential Cookies: Required for basic site functionality, including theme preference (dark/light mode) and session management. These do not track you across websites.
• Analytics Cookies: Used by Google Analytics 4 to collect anonymous usage data. These help us improve the Service.
• Ad Personalization Cookies: Used by Google AdSense to serve relevant advertisements. You can opt out of personalized advertising at https://www.google.com/settings/ads.

You can control cookie preferences through your browser settings. Disabling certain cookies may affect the functionality of the Service. For more information about how Google uses data, visit How Google uses information from sites that use our services.

Third-Party Services

We use the following third-party services:

• Google Analytics 4: Anonymous usage analytics. Google's Privacy Policy: https://policies.google.com/privacy
• Google AdSense: Advertising service. Google uses cookies to serve ads based on your interests. You can view Google's privacy practices at the link above.
• Vercel: Our hosting platform. Vercel may collect basic server logs (IP address, request timestamps, and page URLs) for operational purposes. Vercel's Privacy Policy: https://vercel.com/legal/privacy

We do not sell, trade, or transfer your information to third parties for their marketing purposes. We do not use third-party trackers beyond the analytics and advertising services listed above.

Data Retention

Since we do not store your subtitle files, the only data we retain is:

• Analytics data: Retained by Google Analytics for 14 months, after which it is automatically deleted.
• Contact form messages: Retained until we have resolved your inquiry, after which they are deleted.
• Server logs: Retained by Vercel for a maximum of 30 days.

Your Rights (GDPR & CCPA)

Depending on your location, you may have the following rights regarding your data:

• Right to Access: Request a copy of the personal data we hold about you.
• Right to Deletion: Request that we delete any personal data we have collected about you.
• Right to Opt Out: Opt out of Google Analytics tracking and AdSense personalized advertising.
• Right to Data Portability: Request a machine-readable copy of your data.
• Right to Withdraw Consent: Withdraw consent for data processing at any time.

To exercise any of these rights, please contact us. We will respond to your request within 30 days as required by applicable law. We do not discriminate against users who exercise their privacy rights.

Children's Privacy

The Service is not directed at children under the age of 13 (or 16 in the European Union). We do not knowingly collect personal information from children. If you believe a child has provided us with personal data, please contact us so we can delete it.

International Data Transfers

Our service is hosted on Vercel's infrastructure, which may involve data transfers to servers located in the United States and other countries. When we transfer data, we ensure appropriate safeguards are in place, including Standard Contractual Clauses where required by applicable law.

Security

We implement industry-standard security measures to protect the Service and any data we handle. These include HTTPS encryption for all communications, security headers (X-Frame-Options, X-Content-Type-Options, Referrer-Policy), and adherence to security best practices in our codebase. However, since we do not store your subtitle files, the primary security risk is eliminated at the architectural level.

Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last updated" date. Material changes will be notified through the Service. We encourage you to review this policy periodically.

If you have questions, concerns, or requests regarding this Privacy Policy, please contact us. We aim to respond to all privacy inquiries within 48 hours.
