The problem with memory

Never rely on memory again

A calendar reminder only works if you remembered to set it, and it can't see the fine print. TrialGuard reads the actual page, every time.

Capability Manual Calendar Reminders TrialGuard
Catches introductory pricing before it renews Misses them — no one calendars a price change buried in the terms Watches for trial and introductory-offer language on the pages you visit
Helps you find subscription management pages Search through email receipts and account settings Uses the best subscription-management link it can find on the page (often the cancellation page itself), with a search fallback when one isn't available
Local privacy Usually requires syncing to an external calendar account Your tracked trials stay on your device

Under the hood

Built like security software, because it is

Reads the page like a person would

TrialGuard scores the pages you visit against two independent signatures: a $0 free-trial pattern ("start free trial," "7-day free trial") and an intro-promo pattern ("$1 for your first month," "50% off for 30 days," "renews automatically at $29.99"). It only alerts once it's confident — no noise on pages that just mention pricing.

  • Detects duration automatically (7, 14, 30+ days)
  • Extracts intro price → renewal price pairs
  • Works on single-page apps, not just static checkouts

Privacy by design

TrialGuard processes page content locally on your device to detect free trials and introductory offers. Tracked trials and reminder information are stored in chrome.storage.local. TrialGuard does not send your browsing history to a TrialGuard server, sell data to third parties, or require an account.
