TWmeme Chrome Extension · Last updated: 2026-05-11

This Chrome extension lets you type :meme <keyword> inside chat boxes (LINE, Threads, Instagram) to insert a meme from the public TWmeme catalog. It is built and maintained as an open-source side project (github.com/u9511112/twmeme).

What this extension collects

Nothing personally identifiable. Specifically:

• It does not read or store the rest of your chat input — only the trailing :meme <query> pattern, used solely to trigger a meme search.
• It does not transmit your chat content, browsing history, identity, location, or any cookies anywhere.
• It does not use analytics SDKs, tracking pixels, or A/B testing.

What network requests it makes

The only outbound requests are to:

• https://ep-dawn-voice-ao8hd53u-pooler.c-2.ap-southeast-1.aws.neon.tech/sql — to query the public TWmeme meme catalog (PostgreSQL over HTTPS).
• https://pub-26dcc45acd9349968b1ee689f0113ee1.r2.dev/memes/* — to load meme images (Cloudflare R2 public bucket).

These are the same endpoints twmeme.vercel.app uses. The connection is read-only by Postgres-level GRANT permissions (the web_anon role can SELECT public memes and INSERT anonymous search logs only; it cannot read logs back, cannot modify the catalog).

What gets logged on the server side

When you complete a search (the overlay actually returns results), the extension inserts a row into TWmeme's search_queries table containing:

• The query text you typed after :meme
• Whether results were returned (true/false)
• The result count

No IP address, user agent, account identifier, or cookie is sent or stored alongside this row. Logs are used solely to improve catalog coverage — which queries return no results, which memes to add next.

If you'd rather not log queries at all, disable the extension. There is no separate opt-out toggle in v0.0.x.

What gets stored locally (Chrome Storage)

Starting in a later version, the extension may store your last 8 picked memes in chrome.storage.local to provide a "recent" carousel. This data:

• Lives only inside Chrome on your device.
• Is never transmitted off your machine.
• Can be cleared at any time by removing the extension or via chrome://extensions → TWmeme → "Storage".
