Privacy Policy — Post Library

Effective date: 18 July 2026

The short version: everything Post Library saves stays on your own computer. The developer operates no servers, collects no data, and never sees anything you save. The only time any data leaves your device is if you choose to run AI categorization, which sends post text directly from your browser to the AI provider you picked, using your own API key.

What Post Library does

Post Library saves posts from your own logged-in account's Saved list into a private, searchable library on your device, so you can browse and organize them offline. It works only on content your own account can already see.

Data the developer collects

None. Post Library has no analytics, no tracking, no telemetry, no ads and no developer-operated servers. Nothing you save, type or configure is ever transmitted to the developer.

Where your data lives

Optional AI categorization

Off by default. If you choose to run it, the text of your selected posts (never media files) is sent directly from your browser to the AI provider you selected — Google Gemini or Agnes AI — authenticated with your own API key. The developer is not part of that connection and cannot see it. The provider's own privacy policy governs its handling of that text. Your API key is stored only on your device and is only ever sent to that provider itself.

OCR (reading text inside images)

Optional, off by default, and runs entirely on your device using a bundled engine. Images are never uploaded anywhere.

Why each permission is needed

PermissionUsed for
storage, unlimitedStorageKeeping your library (which can include videos) on your device.

Access to Instagram/Facebook CDN domainsDownloading the images and videos belonging to your saved posts (that is where Threads hosts media files).
Optional AI provider domainsRequested only if you enable AI categorization, to let your browser call the provider you chose with your own key.

Data sharing and selling

Post Library shares no data with anyone and sells nothing. There is nothing to share — the developer holds no user data.

Deleting your data

You are in full control: use Clear library in the extension to remove all records, delete the media folder in Downloads like any normal files, and uninstall the extension to remove its local storage. Nothing persists anywhere else.
