The apps provided by periodicalapps do not collect any data about users.

We aim to provide useful apps, not monetise users’ data or serve them ads.

If you use the apps from the playstore or app store, then anonymised usage metrics (installs, crashes, uninstalls) are tracked by Google and Apple, respectively. If you make contact, then we will use that data only to respond (if you choose to provide a return email address) and to make improvements to the apps.
