Blobster Privacy Policy

Effective date: June 15, 2026

Blobster is a local-first browser extension for opening, formatting, inspecting, editing, searching and copying structured developer data in the browser.

Blobster may process data you choose to open, including local files, pasted text, URLs, selected text, link targets, page text, raw structured pages, API responses, Markdown, .env files, JWTs, HAR files, OpenAPI specs and extension settings.

Blobster processes this data locally in your browser.

Blobster does not upload document contents, pasted text, API responses, selected text, edited documents, or local files to any server.

Blobster does not use accounts, cloud sync, telemetry, analytics, advertising, public paste URLs, remote executable code or a backend service.

Blobster stores settings locally, such as theme, view preferences, pane size and auto-open preferences.

Recent documents are off by default. If enabled, Blobster stores local metadata such as document name, format, size and timestamp. Blobster does not store document contents or edited document contents in extension storage.

Temporary incoming documents may be stored briefly in browser extension storage to pass data between extension entry points and the viewer. This storage is local to your browser and is not transmitted to Blobster or any third party.

Blobster requests website access so it can detect and open high-confidence raw structured pages, import selected text, open links and handle supported structured file URLs.

Website content is used only to provide these Blobster features. Blobster does not track browsing history for analytics or profiling, and it does not sell, transfer or share website content with third parties.

Blobster does not sell or transfer user data to third parties except as required by law.

Blobster does not use user data for purposes unrelated to its single purpose, and it does not use user data to determine creditworthiness or for lending purposes.
