What We Collect

When you use Summario, we collect the following:

• •YouTube video URLs you choose to summarize
• •Your account email (if you create an account)
• •Usage counts — how many summaries, chats, and digests you've used
• •Notes you write on videos in your library
• •Channel subscriptions you set up for daily digests

Chrome Extension

The Summario Chrome extension is a client-side companion to the Summario web app. This section describes the extension's specific data handling.

Permissions we use and why

• Storage: saves your preferences (theme, UI language, chat history for the open video) locally in your browser.
• Alarms: runs a periodic sync to refresh account state and a keep-alive alarm during long AI operations.
• Cookies: detects sign-in/sign-out events on app.summario.net so your auth state stays in sync. Used only for app.summario.net.
• Scripting: re-injects the Summario widget on YouTube after extension updates, so you don't need to hard-refresh.
• Active Tab: reads the current tab's URL only when you click the Summario popup, to identify the open YouTube video.
• Identity: enables “Sign in with Google” via the Chrome identity API. Used only when you click the sign-in button.

Data we access on YouTube

When you use Summario on a YouTube watch page, we access the currently-open video's URL, title, and transcript. We do not access or collect your browsing history, data from other tabs, or activity on any site other than youtube.com. We do not track your viewing behavior across YouTube videos.

How AI processing works

Your video content (transcript, title, and any questions you ask in chat) is processed by third-party AI services to generate summaries, takeaways, and chat responses. These AI providers are contractually bound not to retain or train on your data. We use multiple AI providers for redundancy and performance.

Local vs. server storage

Preferences (theme, language, chat history for the current video) are stored in chrome.storage.local on your device and never leave your browser. Your account information, subscription status, and saved video summaries are stored on our servers.

Cookie sync

The extension uses the cookies permission solely to detect when you log in or log out on app.summario.net. This keeps your authentication state in sync between the web app and the extension. We do not read cookies from any other site.

Deletion rights

You can delete your account at any time from the Settings page at app.summario.net/settings under Account → Danger Zone. Deletion is scheduled for 30 days after you confirm — during that grace period you can cancel any time by signing back in, and we'll send a confirmation email when you request deletion. After 30 days the account row and every record linked to it are permanently removed. Uninstalling the extension removes all local data immediately.

YouTube trademark

Summario is an independent product and is not affiliated with, endorsed by, or sponsored by YouTube or Google LLC. YouTube™ is a trademark of Google LLC. We access publicly visible YouTube page content via your browser; we do not use YouTube's Data API v3 for the summarization feature.

Highlights export (Notion & Obsidian)

Pro users can save text selections from YouTube videos as “highlights” and export them to Notion or Obsidian.

• Notion: when you connect Notion, you authorize Summario to write to a workspace you choose. Your Notion access token is stored on our servers and used only to push highlights you explicitly export. We do not read content from your Notion workspace outside of the pages we create. You can revoke access at any time from your Notion settings.
• Obsidian: uses a local URI scheme (obsidian://) to open your local Obsidian app with the highlight content. No data is sent to a third-party server; the URI is generated locally and opened in your browser.

Both export destinations are optional. If you do not connect Notion and do not use the Obsidian shortcut, no highlight data leaves Summario's servers.

What We Don't Store

• ✓Full video transcripts — these are processed to generate your summary, then deleted
• ✓Payment details — handled entirely by Stripe. We never see your card number.
• ✓Your YouTube watch history — we only know about videos you explicitly choose to summarize

Data Retention

We keep your data only for as long as you have an active Summario account, plus a short grace period after deletion to let you change your mind. Specific retention windows:

• •Account profile, summaries, highlights, chat history, and integrations — retained while your account is active. When you delete your account, every linked record is scheduled for permanent deletion 30 days later.
• •Usage logs (token counts, cost, request timestamps) — retained while your account is active for billing, abuse prevention, and product analytics. After account deletion these rows lose their user reference and are no longer linkable to you; aggregated rows may be kept indefinitely for service-wide reporting.
• •Transcripts — public YouTube captions cached at the video level, not the user level. Not deleted with your account because they are not personal data.
• •Backups — encrypted database backups are kept for 30 days. Data removed from the live database persists in backups for up to that window before being overwritten.

Deleting Your Account

You can delete your Summario account at any time:

1. Sign in to app.summario.net.
2. Open Settings → Account.
3. Scroll to Danger Zone and click Delete account.
4. Confirm with your password (or, if you signed in with Google or a magic link, by typing your email exactly).

After you confirm, your account enters a 30-day grace period:

• •All active sessions are revoked across web and mobile.
• •If you have a Pro subscription, it is scheduled to end at your current billing period — no further charges will be made.
• •A confirmation email is sent so you have a written record.
• •You can cancel any time during these 30 days by signing back in — Settings will show a banner with a “Cancel deletion” button.

After 30 days, our retention job permanently deletes your user record and every record linked to it (settings, subscriptions, summaries, highlights, notes, integrations, chat sessions and messages, digests, WhatsApp verifications, refresh tokens, API tokens, and sync logs). This deletion is irreversible — we cannot recover your data after the grace period ends.

Third-Party Services

Summario uses the following third-party services:

• •Stripe — payment processing. Subject to Stripe's privacy policy.
• •Twilio — WhatsApp digest delivery
• •Vercel — hosting and infrastructure
• •Third-party AI service providers — AI processing for summaries and chat. Transcripts are processed and not retained.
• •PostHog — anonymous usage analytics

Cookies

We use session cookies to keep you logged in and PostHog analytics cookies to understand how people use Summario. No advertising cookies. No cross-site tracking.

You can:

• •Request a copy of all data we hold on you
