SRT JSON to SRT Zero Upload / Local Browser Engine
Presets
Effective Date: November 12, 2026 / Zero Transcript Upload

Privacy Policy and Zero-Upload Data Guarantee

This Privacy Policy explains what data JSON to SRT (jsontosrt.com) never touches, what minimal aggregate telemetry is collected in production, and how you can exercise your privacy and opt-out rights.

1. Explicit Zero-Upload Guarantee for Audio and JSON Files

Your transcript JSON files, pasted text, speaker labels, filenames, and exported subtitles never leave your browser RAM.

  • When you select or drop a .json file on any JSON to SRT converter route, your browser reads the file locally in memory using File.text().
  • No backend upload API, cloud storage bucket, database, or server-side transcription worker exists behind jsontosrt.com.
  • Converted .srt, .vtt, .txt, and .csv outputs are generated inside your tab via Blob URLs and cleared from volatile memory as soon as you close or reload the tab.
  • You can verify this guarantee directly in your browser Developer Tools (Network panel) or disconnect Wi-Fi after loading the page and convert multi-megabyte files offline.

2. Anonymized GA4 Telemetry (page_view and subtitle_export)

On the live production domain, we use Google Analytics 4 (GA4) with IP anonymization enabled (anonymize_ip: true) and Google Signals advertising personalization disabled to understand aggregate tool usage and search performance.

Event Name Parameters Recorded Explicitly Excluded Data
page_view Page path (for example /whisperx-diarized-json-to-srt/), HTTP referrer domain, coarse device viewport category, and browser language. No user account IDs, email addresses, or cross-site ad profiles.
subtitle_export export_action (copy or download) and output_format (srt, vtt, txt, or csv). Never includes transcript text, cue dialogue, speaker names, uploaded filenames, or file byte contents.

During local development and automated Playwright testing on 127.0.0.1 or localhost, external Google tag scripts are suppressed so zero external network requests occur.

3. Static Hosting, Edge Security Logs, and Email Contact

  • Cloudflare static delivery: Static HTML, CSS, and JavaScript assets are served globally over HTTPS through Cloudflare Workers Static Assets. Cloudflare processes transient connection metadata (request IP address, TLS version, HTTP user-agent, and requested URL path) strictly for routing, caching, and automated DDoS protection.
  • Direct email inquiries: If you voluntarily send an email to hello@jsontosrt.com, we receive your sender address and message body via Cloudflare Email Routing solely to reply to your support request. We never add support senders to marketing lists or sell contact information.

4. Cookies and Opt-Out Rights

The core subtitle converter sets zero functional or authentication cookies and does not use localStorage or IndexedDB to persist transcripts. When GA4 loads on the production site, Google sets first-party measurement cookies (_ga and _ga_*) to distinguish aggregate sessions.

You can block or opt out of GA4 measurement at any time with zero degradation to converter functionality:

  • Use privacy-focused browsers (such as Brave, Firefox Enhanced Tracking Protection, or Safari Intelligent Tracking Prevention) or content blockers (such as uBlock Origin), which block googletagmanager.com scripts while keeping all local parsing intact.
  • Install the official Google Analytics Opt-out Browser Add-on.
  • Clear cookies for jsontosrt.com in your browser site settings at any time.

5. GDPR, UK GDPR, and CCPA / CPRA Summary

  • European Economic Area and UK visitors (GDPR / UK GDPR): Because transcript conversion happens strictly on your own device, jsontosrt.com never acts as a processor or controller of personal data contained inside your audio transcripts. For email correspondence you initiate, we process your message to respond to your inquiry and delete support threads upon request.
  • California residents (CCPA / CPRA): We do not sell or share personal information as defined under the California Consumer Privacy Act, and we do not engage in cross-context behavioral advertising.
  • Exercising your rights: To request access to or deletion of any email correspondence sent to us, or to ask a privacy question, contact hello@jsontosrt.com. Also review our About page and Terms of Use.
