Privacy Policy (English summary)

What this service does. 洋流雷達 (Current Radar) is a web tool that finds public Threads posts announcing in-person giveaways and events, extracts the time and place, and shows them on a radar and map relative to the visitor's location.

Website visitors. No sign-up or login is required. If you allow location access, your approximate coordinates are sent to our server only to look up nearby events; they are not stored or logged. Preferences (theme, range, manual location) stay in your browser's localStorage. When you submit a Threads post link or report that a giveaway has ended, we store the report together with a salted hash of your IP address (not reversible) only for rate limiting; these records are deleted after 30 days.

Threads data. Using the Meta Threads API we search public posts for a fixed keyword. We process the post ID, text, timestamp, author's public username and permalink, solely to extract the time and location of giveaways and events and display them with a link to the original post. We do not use the data for advertising, profiling, or sale, and we do not share it with third parties. Posts and extracted data are automatically deleted after 30 days. For post links submitted by users, we read that single post's public embed page to obtain its text and author's public username, process it the same way, and re-read it every 30 minutes to detect deletion or edits. The only access token stored is the operator's own Threads token used to call the API.

Processors. Meta Threads API, public news RSS feeds (Yahoo News; only title, short excerpt and link are kept), the public route data of the official 台北大洋流 site, Cloudflare (Workers, D1, Workers AI, Pages), OpenStreetMap Nominatim and tiles, GitHub Pages.

Deletion and contact. See the data deletion instructions. Questions: GitHub Issues.
