Know before it happens. Every time.

Every feature in Subproof is powered by a single core idea: you should always know before money leaves your account or coverage runs out. Smart Reminders is the engine behind that promise — a notification system that watches your subscriptions, warranties, and agreements and sends you an email alert at exactly the right time.

Subproof sends email alerts before subscription renewals, warranty expiries, free trial conversions, and agreement auto-renewals. The default timing is 7 days before most events, giving you a useful window to act — cancel, negotiate, extend, or simply be aware. Pro users get advanced alert configuration and can set independent reminder windows for every item they track.

On the free tier, users receive a 90-day price check reminder for subscriptions — a gentle nudge to review whether you're still getting value. Plus users unlock free-trial-ending alerts, which are one of the most practical features Subproof offers: you'll be told before a trial converts to a paid subscription, with enough time to cancel if you don't want it.

There are no surprise charges with Subproof. Whether it's a £9.99 monthly renewal you forgot about, a warranty expiring this week, or a phone contract about to auto-renew for another 24 months — Smart Reminders will tell you first. Every time, without exception.
