Privacy Policy

Speedrun is a browser extension that generates AI-powered summaries of videos, articles, PDFs, and X posts you choose to speedrun. This policy explains what data we collect, how we use it, and your rights regarding that data.

When you click "Speedrun" on a supported page, we collect and process the following data needed to generate summaries and audio narration:

• Source metadata: URL, title, publisher/site name, duration or word count, and thumbnail URL when available
• Source content: Video transcripts/captions, article text, PDF text, and X post content/transcript text for the page you explicitly choose to speedrun
• Public comments: Top YouTube comments for the "What Viewers Said" feature
• Generated outputs: Summary text, audio narration, and timing metadata used for playback
• Device stats identifier: A random device ID generated by the extension and aggregate usage metrics (content minutes and listening minutes)
• Diagnostic events: Error and crash telemetry used to keep the extension reliable

• Personal information (name, email, address)
• Account credentials or passwords
• Full browsing history collection or continuous page tracking
• Private messages, email content, or form inputs not required for summarization
• Cookies or tracking pixels

The collected data is used solely for:

1. Generating summaries: Selected source content is sent to our AI service to create readable summaries.
2. Caching: Summaries are cached to provide faster responses for previously summarized sources.
3. Comment analysis: Public comments are processed to generate the "What Viewers Said" section.
4. Usage stats: Aggregate listen/consume minutes are used for your in-extension stats.
5. Reliability: Diagnostic events are used to monitor crashes and fix extension errors.

Local storage: The extension stores settings, recent speedrun history, and a random device ID in Chrome storage on your device.

Server storage: To support generation, caching, playback, and sharing, our servers (hosted on Convex) store source records (for example source ID/URL/title/publisher, duration, and thumbnail), extracted source content and optional comments, generated summary text, generated audio narration files with timing metadata, generation job metadata, and pseudonymous device stats.

Speedrun uses the following third-party services:

• Convex: Backend infrastructure for API, database, and audio file storage
• OpenRouter: AI service provider for summary generation and page analysis
• Inworld: Text-to-speech provider for generated narration audio
• Supadata: Transcript retrieval for supported X post/video sources
• Sentry: Error monitoring and crash diagnostics

Source content, generated outputs, and diagnostics are processed through these services to provide Speedrun functionality and reliability. Please refer to their respective privacy policies for information on how they handle data, including network metadata such as IP addresses in their own logs.

Cached summaries are retained to improve service performance. Local extension data can be cleared by uninstalling the extension or clearing extension data in Chrome settings. A new pseudonymous device ID is generated when you reinstall the extension. Server-side records associated with a previous device ID may remain.

Speedrun supports shareable summary pages. Anyone with a valid share link may be able to view the associated summary and audio, so you should avoid speedrunning and sharing content that is private or sensitive.

You have the right to:

• Uninstall the extension at any time to stop all data collection
• Clear local storage data through Chrome's extension settings
• Contact us with questions about your data

Speedrun is not directed at children under 13. We do not knowingly collect personal information from children. Since we don't collect personal information from any users, this is not applicable.

We may update this privacy policy from time to time. Changes will be reflected on this page with an updated "Last updated" date. Continued use of the extension after changes constitutes acceptance of the updated policy.
