Description
SubDupes — Smart Subscription Manager
Stop losing money to forgotten subscriptions, sneaky price hikes, and overlapping trials. SubDupes works silently in the background to track every subscription you pay for — automatically.
────────────────────────────
🎯 WHO THIS IS FOR
────────────────────────────
You sign up for things. You forget about them. You get charged. Repeat.
SubDupes is built for anyone who:
- Pays for more than 3 subscriptions (most people have 8+)
- Has been surprised by a renewal charge they forgot about
- Suspects they're paying for a service they no longer use
- Wants to know if Netflix just raised their price again
────────────────────────────
✅ WHAT SUBDUPES DOES
────────────────────────────
🔍 AUTO-DETECTS SUBSCRIPTIONS
SubDupes reads checkout and pricing pages as you browse. When it spots a subscription, it shows a discreet popup letting you save it with one click — no manual entry needed.
📧 IMPORTS RECEIPTS FROM GMAIL
Visit Gmail and SubDupes automatically scans for subscription receipts. Found one? It shows an import prompt so you can add it to your tracker instantly.
💸 CATCHES PRICE HIKES
If you revisit a site where your stored price no longer matches what's shown on the page, SubDupes flags it instantly. No more silently paying more than you agreed to.
✅ "ALREADY SUBSCRIBED" REMINDER
Visiting a site you're already paying for? SubDupes shows a green toast in the corner displaying exactly what you pay — so you don't accidentally sign up for the same thing twice.
📊 FULL SUBSCRIPTION DASHBOARD
Everything syncs to your personal dashboard at app.subdupes.com — a clean list of all your subscriptions with amounts, billing cycles, renewal dates, and more.
🔔 RENEWAL REMINDERS
SubDupes notifies you 1, 3, and 7 days before a subscription renews, so you can cancel before getting charged if you've changed your mind.
📴 WORKS OFFLINE
No internet? No problem. SubDupes saves subscriptions locally and syncs them to your account the moment you reconnect.
🖱️ RIGHT-CLICK TO SAVE
Highlight any text on a page (like a price or plan name), right-click, and choose "Save to SubDupes" — great for pricing you spot on comparison pages.
────────────────────────────
🔒 PRIVACY FIRST
────────────────────────────
SubDupes only reads page content to identify subscription signals. It does not:
- Record your browsing history
- Track pages unrelated to subscriptions
- Sell your data to anyone — ever
Your subscription data is stored in your own account and never shared. Full privacy policy: subdupes.com/privacy
────────────────────────────
