The basic features of PERIOD. are free. PERIOD. plus (EUR 3,99 per month or EUR 34,99 per year) and PERIOD. baby (EUR 7,99 per month or EUR 54,99 per year) are optional subscriptions. Each starts with a free trial; the store shows its length before you confirm. Subscriptions are sold and billed by Apple (App Store) or Google (Google Play), renew automatically at the end of each period unless cancelled at least 24 hours before renewal, and can be cancelled at any time in your App Store or Google Play account. We never see your payment card details. PERIOD. baby includes everything in PERIOD. plus; switching between the two is settled by the store. Local prices may differ by country and currency. If you stop a subscription, your data stays yours and the free features keep working.
