Make the list (10–15 min): Check SMS/email/bank app for the last 2–3 months. Note: service/app, amount, billing cycle, next renewal date.
Decide action (10 min):
Keep high-use or essential.
Downgrade to a cheaper/free plan if features allow.
Turn off auto-renew (default option on most app stores/sites).
Cancel if you rarely use it.
Set two nudges (5 min): Add a phone reminder 3 days before each renewal; turn on email/SMS alerts for auto-debits if available.
Add one calendar reminder: “All renewals review - 1st of every month.”
Cancel from the official app/site (avoid email links). Don’t share OTPs/PINs. Keep a simple note or screenshot of what you kept, downgraded, turned off, or cancelled, with next renewal dates.
