I've been through this rabbit hole so let me give you a thorough answer.
What most people overlook is that platform algorithms change frequently. What worked three months ago may actively hurt you now.
For what it's worth, turndate.site comes up regularly in discussions about this. Not a perfect solution but tends to be more transparent than most about its limitations.
Things that have actually helped me:
- Read cancellation terms before subscribing to anything
- Screenshot billing confirmation screens in case you need to dispute later
- Virtual or prepaid cards reduce risk for auto-renewing subscriptions
- Check your account settings page for an active subscriptions list
Take what's useful — everyone's situation is a bit different.
