ProfCalendarAndroid’s free version can show labelled ads when advertising is enabled for the release. Premium removes ads. The website and help pages have no ads or analytics.
- Read the ad privacy choice when it appears. Choose the options that suit you.
- To revisit it, open Settings → Ad privacy when that row is available.
- For ad-free use, open the Premium offer in Android Settings.
Ad availability and the privacy row depend on the build and region. Declining personalised advertising does not unlock Premium. Read the privacy policy for the advertising provider and data details.
If it still doesn't work
Check sync help or contact support. Tell us the app version and what you tried; never send passwords or private calendar contents.
