StubWatch — Subscription Reminder

About

Every subscription, one glance — and a nudge before you get charged again.

StubWatch is a minimal, 100% local subscription tracker. Log what you pay for,
get reminded before each renewal, and see exactly what it all costs per month
and per year. No account. No credit card connection. No network access at all.

🎫 TRACK LIKE TICKET STUBS
• Each subscription is a ticket stub with a live countdown to its next renewal
• Sorted by renewal date — what charges next is always on top
• Monthly & yearly totals, split by currency (¥ / $ / € / £), no fake exchange rates

⏰ NEVER FUND A ZOMBIE SUB AGAIN
• Per-subscription reminders, N days before renewal (you choose)
• System notifications plus a badge count on the toolbar icon
• Recurring plans roll forward automatically after each billing date
• One-time mode tracks free-trial deadlines without counting toward spend

📦 220+ SERVICES BUILT IN
• AI (Claude, ChatGPT, Gemini, Cursor…), streaming (Netflix, YouTube, Bilibili…),
  music, cloud storage, dev tools, gaming, news, health, finance — and household
  bills like rent, utilities, broadband and insurance
• Official brand icons, bundled inside the extension
• Searchable in English and Chinese; every price is an editable reference default
• Anything not listed: add it manually with an emoji or your own uploaded icon

🔒 PRIVATE BY ARCHITECTURE
• All data lives in your browser's local storage
• The extension requests zero host permissions — it is technically unable to
  send your data anywhere
• Export / import JSON backups to move between computers

🌐 ENGLISH & 中文
• English by default, switch to Chinese in Settings
• Dates, prices and notifications are fully localized

Permissions used: storage (save your list locally), alarms (periodic renewal
check), notifications (renewal alerts). Nothing else.
