Seritor is a local-first Chrome extension. All bookmarks, library items, notes, labels, and settings are stored in your browser using Chrome's storage API. Nothing is sent to any server. There are no accounts to create and no sign-in required.
The extension collects no personally identifiable information. The website collects email addresses only if you choose to subscribe to product updates.
All core processing occurs within your browser sandbox. Seritor does not transmit, store, or process your data on any external server. Your AI conversations, bookmarks, and library content never leave your machine.
| Data type | Collected? | Detail |
|---|---|---|
| Conversation content | No | Never transmitted. Stored locally only. |
| Bookmarks and notes | No | Stored locally via Chrome storage API. |
| Library items | No | Stored locally. Never transmitted. |
| Email addresses | No | The extension does not collect email addresses. |
| Browsing history | No | Not accessed or stored. |
| Anonymous error reports | Opt-in only | When enabled by the user in Settings, anonymous crash data is sent to Sentry for stability improvement. Reports contain no conversation content, no bookmark data, no personally identifiable information, and no email addresses. |
Seritor requests only the permissions necessary to function. Each permission is justified below.
| Permission | Purpose |
|---|---|
| storage | Storing bookmarks, library items, conversation metadata, labels, notes, and user settings locally in the browser. |
| tabs | Opening new tabs for scroll-to-message navigation and export output. Seritor does not read tab content or browsing history. This permission is used only for chrome.tabs.create and chrome.tabs.update. |
| Host permissions | Limited to four domains: claude.ai, chatgpt.com, gemini.google.com, and grok.com. Required to inject bookmark flags into conversation pages. No other websites are accessed. |
Seritor includes an optional anonymous error reporting feature powered by Sentry. This is disabled by default and can be enabled in the extension's Settings panel.
When enabled, only technical error data is transmitted: error type, stack trace, browser version, and extension version. Error reports contain no conversation content, no bookmark text, no library content, no notes, no labels, no email addresses, and no personally identifiable information.
You can disable error reporting at any time in Settings. The change takes effect immediately.
The Seritor website (seritor.app) links to Buttondown for product update subscriptions. Clicking "Subscribe" takes you to Buttondown's website where you can enter your email address. Your email is stored by Buttondown and used solely for product update communications. Seritor's website does not collect, handle, or store email addresses.
You can unsubscribe at any time using the link in any email. We do not sell, share, or transfer email addresses to third parties.
The website does not use tracking cookies, analytics scripts, or third-party advertising. Standard server access logs may be retained by our hosting provider.
| Service | Purpose | Data shared |
|---|---|---|
| Sentry | Error reporting (opt-in) | Anonymous crash data only. No PII, no content. |
| Stripe | Payment processing | Payment details are handled entirely by Stripe. Seritor does not store card numbers or payment credentials. |
| Buttondown | Product update emails | Email address, entered on Buttondown's website by the user. Not collected by Seritor. |
All extension data is stored locally in your browser. Uninstalling Seritor removes all local data permanently. There is no cloud backup and no way to recover data after uninstallation.
To delete specific data without uninstalling, you can remove individual bookmarks, library items, labels, and notes within the extension popup.
Seritor complies with Chrome Web Store's User Data Policy. The extension's single purpose is to provide a local-first bookmark management tool for AI conversation platforms. All processing occurs within the user's browser. No user data is sold or transferred to third parties. No data is used for purposes unrelated to the extension's core functionality.
Data classification: No Personal Information.
