Change to yearly or monthly billing cycle

Switch plans from the billing portal: click Billing in the app, or go to https://filteronme.com/billing. Then click Update subscription and pick the plan you want.

Monthly → yearly: takes effect immediately. You get a prorated credit for the unused time left on your current month, applied straight to the yearly charge. For example, if you're halfway through your monthly cycle, you get a 50% credit toward the yearly plan.

Yearly → monthly: takes effect at the end of your current yearly term, not immediately. There's no proration and no immediate charge — you keep yearly access until it runs out, then billing switches to monthly.
