Privacy

What Muntuza collects, why, and what you can ask us to do about it.

Who we are

Muntuza Screen is run by MUNTUZA LTD, which is responsible for your data. Contact: contato@muntuza.com or WhatsApp. Full company details are at the end of this page.

This website

It uses no cookies, no analytics and no forms. The web server keeps technical logs (IP address and browser) for security and to keep the site running.

If you message us on WhatsApp, we receive your number and your message so we can reply. WhatsApp handles that data under its own policy.

The Muntuza Screen app: what we collect

• Your name, email and phone number, so we can identify your account and reach you about your campaigns.
• The posters and campaign details you upload, so we can show them on the screens you booked.
• Playback records — which advert played on which screen, and for how long. This is how campaigns are billed and how venue partners are paid.

What we never do

We do not track you across other apps or websites, and we do not sell or share your data with advertising networks. We never see or keep your card details. When paid advertising goes live, payments will be handled by our payment provider, not by us.

Who else sees it

Posters and campaign text are sent to OpenAI to run the automatic content check, and to generate a poster if you ask for one. Sign-in, your data and the poster files are held by Supabase, our hosting provider, in London. Nobody else receives your data.

Why we can use your data

To perform our contract with you (account and campaigns), to meet legal obligations (financial records), and for our legitimate interests (security, content checks and replying to people who contact us).

How long we keep it

• Account data, posters and campaigns: for as long as the account exists; erased when it is deleted.
• Financial and playback records: 6 years, without your name once the account is deleted, because the law requires it.
• Enquiries from people who did not become customers: 12 months.

Your rights

You can ask for a copy of your data, ask us to correct or erase it, and delete your account from inside the app at any time. We reply within one month. If you are not happy, you can complain to the ICO, the UK data protection regulator (ico.org.uk).

Delete your account

In the app: Settings → Delete my account. Before you confirm, the app shows what happens: you can no longer sign in, your name and contact details are erased, and any adverts running come off the screens straight away. Financial records are kept without your name, because the law requires it. It cannot be undone.

If you cannot sign in, ask on WhatsApp or at contato@muntuza.com, from the phone number or email on your account. We confirm it is you and delete it within one month.

Support

Questions about the app, a campaign or a screen: WhatsApp or contato@muntuza.com.
