Privacy policy
Last updated 16 August 2026
This policy explains what personal information Muhimma collects, why we collect it, and what we do with it. It covers this website, our staff console, and the messages we exchange with people over WhatsApp Business.
Who we are
Muhimma operates this website and the private staff console at messaging-console.primary.muhimma.app. If you have a question about this policy or about information we hold, write to support@muhimmaapp.com.
What we collect
- Contact details — name, WhatsApp phone number and, where you give it, email address.
- Message content — the messages you exchange with us over WhatsApp, including any photos, documents or other files you send, and delivery and read status for messages we send you.
- Participation information — where you take part in a study, the responses and scheduling details you provide.
- Account information — for staff and client administrators, the email address and password used to sign in to the console.
We do not use advertising cookies or third-party tracking on this site. The console stores a sign-in token in your browser purely to keep you signed in.
Why we use it
- To reply to you and run the conversation you are part of.
- To operate research studies, including recruitment, scheduling and follow-up.
- To provide the messaging service to the client whose workspace you are in contact with.
- To keep records required for security and for resolving disputes.
How your messages are delivered
Messages are sent and received over the WhatsApp Business Platform. To deliver them, your phone number and message content pass through Meta Platforms (which operates WhatsApp) and through our Business Solution Provider. We do not control WhatsApp's own handling of your data; Meta's privacy terms apply to it in addition to this policy.
Where it is stored
Our systems and data are hosted on servers in Germany. Access is restricted to Muhimma staff and to administrators of the client workspace concerned, and every workspace is isolated from every other.
How long we keep it
We keep conversation records for as long as needed to run the study or service they relate to and to meet our record-keeping obligations, after which they are deleted. You can ask us to delete your information sooner — see below.
Sharing
We do not sell personal information. We share it only with the client whose study or service you are engaging with, with the providers that deliver our messages and host our systems, and where the law requires it.
Your choices
- Stop receiving messages — reply STOP to any WhatsApp message from us, or email us, and we will stop.
- Access, correction and deletion — write to support@muhimmaapp.com and we will act on your request.
Security
Traffic to this site and to our console is encrypted in transit. Provider credentials are encrypted at rest. The console is private and requires an account issued by an administrator; it is not open to public registration.
We will never ask you for a password by WhatsApp, email or phone, and we never ask you to sign in to any service other than our own. If you receive a message claiming to be from Muhimma and asking for credentials or payment, it is not from us — please report it to support@muhimmaapp.com.
Changes
If we change this policy we will update the date at the top of this page.
