Frequently asked questions

Can I change plans anytime?: Yes. Upgrades take effect immediately so you get the new features right away. Downgrades take effect at the end of your current billing period, so you keep everything you are paying for until then.
Is there an annual discount?: Yes. Paying yearly gives you 3 months free on every paid plan: you pay for 9 months and get 12.
Can I cancel anytime?: Yes. You can cancel whenever you like. Your plan stays active until the end of the current billing period, with no further charges after that.
