You can close your MBX Reach account and delete its data whenever you want, from the Android app or from mbxreach.com. You do it yourself; nobody has to approve it.
Send us a deletion request from the privacy form, using the email address of the account. We check that the account is yours and delete it within 30 days.
Everything is removed from the live service at once and is gone from our backups within 30 days.
Only the records the law obliges us to keep, such as invoices, for as long as it requires, and a minimal pseudonymous record that stops the free trial from being claimed again.
Full details are in the Privacy Policy and in Trial, cancellation and refunds.
