Privacy

Last updated 26 October 2026

Nossa helps you save homes you like from any property site, rank them by what matters to you, and decide with the people you’re moving with. It is built to know as little about you as it can.

Who we are

Nossa is made by Theos Studio, an independent studio in the United Kingdom (“we”). We are the controller of the little personal data described here. Write to hello@theos.studio about anything on this page.

What stays on your phone

The homes you save, your priorities and the places you go are kept on your phone.

When you share a listing to Nossa, the page is read on your phone. Nossa keeps the facts (price, rooms, postcode, location), the link and the address of the listing’s main photo. Your phone keeps one small copy of that photo so the home is easy to recognise; it never goes to our server. Nossa doesn’t copy the listing’s description.

Journey times and what’s nearby are worked out for your phone and kept on it.

Feedback, if you send it

If you use Send feedback, we keep the words you wrote, the app version, and an email address only if you give one so we can reply. Write to hello@theos.studio to have it deleted.

Backup and sharing, if you sign in

Signing in is optional and uses Sign in with Apple. Nossa asks Apple for no name and no email. We keep only a scrambled form of the identifier Apple gives us.

When you’re signed in, your list is backed up to our server so a new phone or a deleted app doesn’t lose it: the homes, your priorities, the places you go (as a postcode or address and its map point), your viewing notes and your viewing photos.

Viewing photos are made smaller and lose their location and camera details before they leave your phone. They are stored privately and only the people on your list can open them.

If you share your list, the people you invite see its homes, your first name, and the notes and photos you add. Each of you keeps your own priorities.

You can delete your account in the app: tap the person button at the top of your list, then Delete account. Everything backed up is deleted, including photos of lists only you were in. A shared list stays with the others, with the notes and photos you added to it.

Looking things up

To work out journeys and what’s nearby, Nossa sends a home’s map point (or, when the listing has none, its postcode and address) and your places’ map points to our server. Our server asks postcodes.io (for a UK postcode’s map point), OpenStreetMap’s Nominatim (for any other address’s map point) and Transport for London (for journeys in London). They see our server, not you. Parks, shops, gyms and stations come from our own copy of OpenStreetMap, which covers the UK for now. These lookups aren’t stored.

Nossa Plus

Purchases are made and charged by Apple through the App Store. To know what you’ve bought, Nossa uses RevenueCat, which receives your purchase receipts and a random identifier for this copy of the app, not your name, email or list of homes. Apple’s own privacy policy covers what it does with your payment.

Anonymous counts

To know whether Nossa is useful, the app sends counts such as “a home was saved” or “the app was opened in its second week”, and short error reports when something breaks. A count is a day, an event, a small label and the app version. There is no identifier, nothing from your homes or notes, and our server keeps no IP address or time of day. You can turn this off in the app: tap the person button at the top of your list, then Share anonymous counts.

What Nossa never does

• No adverts and no tracking across apps or websites.
• We never sell or share your data, and never pass your details to agents or landlords.
• Nossa never fetches property sites from a server and never collects listings in bulk.
• Your ranking uses only what you set. Nothing about who you are enters it, and nothing paid ever moves it.

Where it’s kept and who to ask

Backups and photos are stored with Cloudflare. Nossa is made in the United Kingdom. Under UK and EU law you can ask us what personal data we hold about you, and to correct or delete it: write to hello@theos.studio. You can also complain to the Information Commissioner’s Office (ico.org.uk).

Children

Nossa collects nothing from anyone, children included, beyond what’s described here.

Changes

If this page changes, the date at the top changes too, and anything that matters will be said in the app.
