The Privacy-First Subscription & Free-Trial Guardian
Detect recurring charges and free trials automatically as you browse, autofill 200+ plans with 1-click cancel links, and prevent unexpected credit card charges.
Built For Control, Not Data Harvesting
Unlike cloud budgeting apps that sell your banking credentials, Subscription Guardian operates 100% inside your browser.
In-Page Checkout Detection
Automatically surfaces price, billing cycle, and trial lengths whenever you click a subscription or free-trial button on checkout pages.
200+ 1-Click Plan Autofill
Instant pricing rates and direct cancellation URLs for Netflix, ChatGPT, Claude, Spotify, Adobe, Cursor, Apple, and 200+ popular services.
Cancel-Before-Charge Default
Default reminder intent is pre-set to cancel before charge, so you never get billed when trying new SaaS tools and free trials.
100% Local Browser Storage
All subscription records, costs, and alert schedules are saved in chrome.storage.local. No telemetry, no cloud sync, no tracking.
CSV Report Export
Generate finance-ready CSV expense reports with normalized monthly equivalent costs, renewal dates, and payment tags with one click.
System Desktop Reminders
Configurable Chrome alarms deliver desktop notifications at 7-day, 3-day, 1-day, and due-day checkpoints before money leaves your account.
