The Problem We Solve
The average person has 12-15 active subscriptions but only remembers 7-9 of them. Hidden subscription creep costs families hundreds of pounds annually through:
- Free trials that auto-convert to paid plans
- Services that increase prices without clear notification
- Multiple subscriptions for similar services
- Forgotten subscriptions from old email addresses
- Services that make cancellation deliberately difficult
Our Mission
We believe everyone deserves transparency in their financial subscriptions. SubKiller empowers you to:
- Discover hidden recurring charges
- Make informed decisions about your subscriptions
- Save money by canceling unwanted services
- Maintain privacy while analyzing sensitive financial data
