Delete your data
Android
Either uninstall Marmareen, or open Settings → Apps → Marmareen → Storage → Clear storage (the wording varies by phone). This deletes your bookmarks, reading history, zikr, duas, settings and saved recitations.
iPhone
Press and hold the Marmareen icon, then choose Remove App → Delete App. This deletes all of Marmareen's data on the phone.
Web edition
In your browser's settings, clear the site data for marmareen.com (or use "Clear browsing data" with "Cookies and site data").
Single items
In the app you can delete a dua (open it, then Delete), a zikr (open it, then Delete), or a bookmark at any time.
