A privacy-first Chrome extension that watches TLScontact for you — and pings your phone the instant a slot drops. Local-only. No servers. Open source. Free.
One click on the Chrome Web Store, or sideload from GitHub if you prefer to audit the source first. Either way, the same MIT code.
The extension auto-detects the tab. Toolbar badge turns green — that's me, watching.
When a slot opens, you get a desktop ping — and, optionally, a Telegram message on your phone.
A real TLScontact session — no edits, no speed-ups. The extension detects the slot and pings you in seconds.
Two lists, same length. I'm only useful if you can trust me — so the second list is as long as the first, and at least as honest.
One popup, seven moods. Same chrome, same restraint. Tone shifts with status — never decoration.
Telegram is the only off-machine path I touch, and it's opt-in. Off by default. You hold the keys.
If you'd rather trust the code than my marketing — please. The classifier is one short, readable file.
