1. Who we are

Gusa Events (“Gusa”, “we”, “us”) is a digital event management platform operated by Melian Software Co. Ltd in Tanzania. Event hosts (“Hosts”) use Gusa to manage guest lists, send invitations, track RSVPs and record contributions (michango). This policy explains how personal data is handled on gusa.co.tz and in our services.

2. Data we collect

Guest details entered by Hosts: name, title, phone number, email address (optional) and invitation type.
RSVP status: whether a guest confirmed, declined or attended.
Contribution records: pledged and paid amounts, payment dates and receipts.
Photobooth content: photos, nicknames, likes, comments and feedback that guests voluntarily upload to an event gallery.
Enquiry details you send us through our contact forms or WhatsApp.
Technical data such as IP address, browser type and pages visited (cookies and Google Analytics).

3. How we use it

Personal data is used only to provide the service: sending event invitations, reminders and receipts, showing RSVP and contribution status to the Host, running the event gate-pass and gallery, answering enquiries, and keeping the platform secure. We do not sell personal data and do not use guest phone numbers for unrelated marketing.

4. WhatsApp and other processors

Invitations, reminders and receipts may be delivered by WhatsApp using the WhatsApp Cloud API provided by Meta Platforms, and by SMS or email through our messaging providers. These providers process message content and phone numbers on our behalf to deliver the messages, under their own terms and privacy policies. Hosting and analytics providers (e.g. Google Analytics) may also process technical data.

5. Legal basis and consent

Hosts are responsible for having their guests’ consent or another lawful basis before adding them to Gusa and messaging them (see our Terms of Service). Guests may stop receiving messages at any time by replying “STOP” or contacting us.

6. Retention

Guest and contribution data is kept while the Host’s event is active and for up to 12 months after the event so Hosts can reconcile accounts, after which it is deleted or anonymised unless the law requires us to keep it longer (for example financial records). Data can be deleted earlier on request – see Data Deletion.

7. Security

We use access controls, encrypted connections (HTTPS), restricted staff access and regular backups to protect data. No system is completely secure, but we work to prevent unauthorised access, loss or disclosure.

8. Your rights

In line with the Tanzania Personal Data Protection Act, 2022, you may request access to, correction of, or deletion of your personal data, object to its processing, and complain to the Personal Data Protection Commission. Contact us using the details below and we will respond promptly.

9. Cookies

We use cookies for essential functions and analytics. You can disable cookies in your browser settings, though some features may not work.

10. Changes

We may update this policy and will change the date above when we do.
