Replace your WhatsApp or Facebook groups with a platform you own
WhatsApp and Facebook groups are where most associations start, because everybody already has the app. They stop working when the group grows: messages drown, newcomers see nothing of the past, and the member list belongs to someone else. This guide explains when to move and how to do it without losing people.
Why associations outgrow WhatsApp and Facebook groups
WhatsApp groups
- Every phone number is visible to every member. In January 2020 the Gaelic Athletic Association told Irish clubs to stop using WhatsApp groups for that reason; the Irish Data Protection Commission answered that groups remain possible when members consent (Newstalk).
- No archive worth the name. A newcomer sees nothing that was said before they joined; the date of the general assembly scrolls away under a hundred reactions.
- No structure. One group per topic multiplies groups, and each member has to be added to each one by hand.
- Hard to answer a GDPR request. The association cannot export what it holds about a member, nor remove a harmful message once its author has left (William Fry, law firm).
Facebook groups
- Not everyone is on Facebook. About 31% of US teenagers used Facebook in 2025, down from 71% ten years earlier (Pew Research Center); many adults refuse an account on principle.
- The algorithm decides who sees your post. Members miss announcements because the feed ranked something else first.
- Rented land. The platform owns the member list and changes its rules when it wants. Meta closed Workplace, its product for organizations, in May 2026 (what happened).
What a private platform gives you instead
| Need | WhatsApp or Facebook group | Private platform such as HumHub |
|---|---|---|
| Separate topics | One group per topic, members added by hand | Spaces per team, branch or activity; members join what concerns them |
| Find past information | Scroll | Search, pinned posts, wiki pages, a file library per space |
| Events | A message and a poll | Calendar with registrations and reminders |
| Privacy between members | Phone numbers or profiles exposed | Profile fields with visibility rules, no phone number needed |
| Phone notifications | Yes | Yes, with the HumHub mobile app and email digests |
| Who owns the data | Meta | The association, with an export at any time |
| Memberships and fees | Not possible | Paid memberships and event tickets with the eCommerce module; HelloAsso synchronization for French associations |
How to move members without losing them
- Pick one reason to come. The calendar of the season, the minutes, the photo gallery: something members look for and cannot find in the chat.
- Prepare three to five spaces with a first post in each, so nobody lands in an empty room. The first 10 steps take an afternoon.
- Invite the active core first: board, coaches, organizers. They answer the first questions of the others.
- Send one invitation link to the old group, with the mobile app links and a sentence on why.
- Announce the date after which important information is posted only on the platform, and keep the old group for small talk or close it.
What it costs
HumHub is free software; running it yourself needs a server and someone to keep it updated. CUZY hosts it with unlimited members for €90/month or €900/year on the Team plan, with a discount for registered non-profits on request and a 14-day free trial. See HumHub for associations and the pricing.
Questions
What is a good alternative to WhatsApp groups for an association?
A private community platform with spaces per group, an archive, events and a mobile app, such as HumHub. Members get notifications on their phone as with WhatsApp, but conversations are organized by topic, searchable, and nobody has to share a personal phone number.
Will members accept another app?
They accept it when it solves a problem they feel: finding the date of the next meeting, the minutes, the photos. Start with one useful thing (the calendar or the documents), invite the most active members first, and announce the day the old group becomes read-only.
Is a private platform GDPR compliant where WhatsApp is not?
A platform hosted in the EU under a processor agreement gives the association control over where the data is, who sees it and when it is deleted, which is what the GDPR asks. A WhatsApp group exposes every member's phone number to every other member and runs on Meta's terms.
