A great many apps quietly harvest data about their users. Ours does the opposite, by design. Rosetta Audio Guides exists to play you a tour, not to track you, and we have built it to collect as little as possible. This page explains plainly what the app does collect, what it deliberately does not, how purchases are handled entirely by the app store rather than by us, how long anything is kept, and the rights you hold over it — all in language meant to be read rather than endured. Last reviewed June 2026.
The data controller is Delta Audio Heritage S.A.E., trading as Rosetta Audio Guides, 11 Sharia al-Gomhoreya, Rashid 22516, Beheira Governorate, Egypt, VAT (ETA) 689-432-571. Data questions go to [email protected].
As little as it can. To work, the app needs to know which tours you have downloaded or bought, so it can play them and restore them if you change phone — and that is essentially the whole of it. We do not require you to create an account to use the app, we do not ask for your name or email to listen, and we do not need your location to play a tour. If you write to support, we hold the message and your reply details. That is the complete picture.
This is the important part. The app does not track your location, does not record which exhibits you lingered at, does not build a profile of your interests, and does not follow you around other apps or the web. It contains no advertising network and no third-party trackers harvesting your behaviour. We make money by selling good tours, not by selling data about the people who listen to them — and we have built the app so that there is very little data to sell even if we wanted to, which we do not.
When you buy a tour or a pass, the payment is handled entirely by the Apple or Google app store, not by us. Your card details go to the app store, never to Delta Audio Heritage; we receive only confirmation that a purchase was made, which is what lets us unlock the content on your device. We never see or store your payment information at all — it does not pass through our systems.
The little we hold to deliver your tours is processed to perform the service you downloaded the app for. For support messages, the basis is your consent and our legitimate interest in answering you. We process nothing for advertising, because we run none.
Your record of downloaded and purchased tours is kept while you use the app, so your library follows you across devices, and is removed when you delete the app and ask us to clear it. Support messages are deleted within a year. We keep what tax law requires of the app-store purchase confirmations, and no more. There is no behavioural data being stockpiled, because we never collected it.
This website, separate from the app, runs no advertising network, no identifying analytics, no social trackers, and sets no non-essential cookies, so there is no cookie banner. It is a set of static pages; the only data it transmits is what you type into the contact form and choose to send.
We make family and children's tours, but a child's use of the app is under a parent's device and a parent's app-store account. We do not knowingly collect personal data from children, and because the app collects so little from anyone, there is essentially nothing personal gathered from a child listening to a family tour. A parent controls the device and the purchases throughout.
When we make an official partner tour, our relationship with the museum is about the content, not about you — we do not share user data with partner museums, and a museum does not learn who has listened to its tour. The partnership is about making a good tour, full stop. Your listening is between you and your phone.
You can ask what we hold about you (it is very little), ask us to correct it, ask us to delete it, and withdraw consent for support correspondence. Write to us and we will respond within thirty days, free of charge. For purchase records held by the app store, the app store's own controls and policies also apply, and we will point you to them if needed.
We protect the little we hold with access controls and encryption in transit, and by the simple fact that we hold almost nothing of value to an attacker — no payment data, no profiles, no location histories. The safest data is the data never collected, and we have built the app on exactly that principle.
It is worth saying outright, because it is unusual enough to matter: we do not make money from your data, and we never will. There is no advertising in the app, no advertising network embedded in it, and no arrangement to sell or share user data with anyone. Our entire revenue comes from people choosing to buy good tours. That is a deliberate choice of business model — the data-harvesting model that funds so many "free" apps is one we rejected at the start, because an app that listens to its users instead of to museums is not the app we wanted to build.
Because you need no account to use the app, we have no marketing list to email you on, and we do not run one. The only email you would receive from us is a reply to a message you sent to support. There is no newsletter, no promotional mail, and nothing to unsubscribe from — if you never write to us, you never hear from us, and that is by design.
All of the above adds up to a simple protection: there is very little about you for anyone to lose, leak or misuse, because we never gathered it. No location history, no behavioural profile, no payment data on our systems, no marketing database. In an age where an app breach can expose a lifetime of harvested data, the safest design is to collect almost nothing — and that is exactly the design we chose. It is good for you, and it lets us sleep at night.
Because your purchases are tied to your app-store account rather than to a profile we hold, moving to a new phone is simple and needs nothing from us: signing into the app store and restoring purchases brings your tours back. This is another consequence of our minimal approach — we do not need to hold an account for you, because the app store already securely links your purchases to you, and we would rather lean on that than build a database of users ourselves.
Many apps embed analytics tools that quietly report your every tap to a third party. Ours does not. We do not track which tours you browse, where you tap, how long you listen, or what you do next. If we want to know whether a tour is working, we ask listeners directly through support and feedback — the human way — rather than surveilling them. It means we know less about aggregate usage than a data-hungry app would, and we consider that a fair price for not watching you.
If we change how we handle data we will update this page and its date. If you are unhappy with how your data has been handled, raise it with us first so we can put it right; you also keep the right to complain to the data-protection authority in your country. Reach us through the contact page, and a real person at the studio will deal with it personally.
