Why we built Plenum

Because families deserve a digital space that respects their privacy, their data, and their children.

You own your data. Period.

Your family's conversations, calendars, todos, and locations belong to you — not to us, not to advertisers, not to anyone else. We store your data so the app works, but it's yours. You can export it. You can delete it. We will never sell it.

Our data promise

We will never sell your family's data. Not today, not ever. This isn't a policy that can change with new management — it's the reason we exist.

An AI-free zone

There are no AI features in Plenum. No chatbots reading your messages, no algorithms deciding what your kids should see, no machine learning models trained on your family's private conversations.

In a world racing to put AI everywhere, we believe some spaces should stay human. Your family chat is one of them. This is a deliberate, permanent choice.

Safe for children

Plenum is designed for families with children aged 6+. Kids get their own accounts with age-appropriate permissions. Adults control what children can access. There are no ads, no algorithmic feeds, no strangers, and no dark patterns.

This isn't a social network with parental controls bolted on. It's a family tool built from the ground up with child safety as a core principle.

Our values

Open standards, no lock-in

Plenum supports iCal and CalDAV, so your calendars sync with Apple Calendar, Google Calendar, Outlook, and any other standard calendar app. Your data isn't trapped.

If you ever decide to leave Plenum, your data comes with you. We believe earning your continued trust is better than making it hard to leave.
