Questions about Free and Premium
Does the free version expire?
No. You can keep using its limited features without a time limit. It is intended for exploring the app rather than organising a complete study routine.
What happens after I add three contents?
The Free limit is three contents in total and one subject. To expand your catalogue, you need Premium; your existing study records are not automatically deleted.
Is Premium a subscription?
No. Premium is a one-time in-app purchase processed by Google Play. There is no automatic renewal.
How much does Premium cost?
Prices vary by country and Google Play account region. The actual price and availability displayed by Google Play at checkout prevail. This website does not process payments.
Can I restore Premium on another phone?
Purchases are associated with the eligible Google Play account under Google Play policies. Use the app’s purchase recovery option when available. Recovering a purchase does not restore study records: local data needs a separate backup.
Do I need a Revisync account or an internet connection?
No Revisync account is required for local studying. Google Play purchases and purchase recovery can require connectivity to Google services.
