Domusia is operated from France. For any question about your data, write to hello@domusia.app.
Your answers to the questionnaire. Style, location, materials, number of rooms. They are what the house is drawn from and are stored with it.
Your email address, if you buy. It comes from the payment page and is used to send you the link to your house. If you tick the box above the offers and then leave the payment page without paying, we send you a single reminder with a link back to it, two hours later. Never a second one.
A one-way hash of your IP address. Not the address itself. It exists only to limit how many free houses can be drawn from the same connection in a day.
A cookie holding a random token, so that the browser which created a house can edit it later. It carries no personal data and expires after ninety days.
Usage measurements. We use PostHog to count how many people start the questionnaire, reach the end and decide to buy. It records pages viewed and actions taken, under an identifier that is not your name. We use it to find out where the product loses people, nothing else.
The photo of your room, if you use Redesign Your Room. It shows the inside of your home, so we treat it accordingly: it is stored privately, never published, and only shown through links that expire after an hour. The redesigns made from it are stored the same way. Anyone holding the link to your order page can see them, so share that link only with people you would show your room to.
Your email address, if you ask us to email you your facade before buying. We send you the elevation and the link to your house, and we keep the address so we can send it again. If you tick “Remind me once, tomorrow”, we record that choice and when you made it, and send a single reminder about that house 24 hours later. It is cancelled if you buy the house in the meantime or unsubscribe, and we never send a second one. Without the tick, there is no reminder. Every email carries an unsubscribe link.
If you use Domusia Pro, our virtual staging service for listings: your email address, to send you sign-in links and receipts; a session cookie that keeps you signed in for thirty days; your credit balance and purchases; and the listings you create, with their photos and staged images. Listing photos are stored privately, shown only through links that expire after an hour, sent to Google Gemini to be staged, and never published or used to train models.
We do not use advertising trackers, we do not profile visitors, and we never see your card details. Payments are handled entirely by Stripe.
Your answers and your house are kept to perform the service you asked for. Your email is kept for the same reason, and, if you agreed to it at checkout, to tell you about new Domusia features. The IP hash is kept to protect the service from abuse, which is our legitimate interest.
Houses and their images are kept for three years after your last visit. Unpaid houses are removed after ninety days. IP hashes are removed after thirty days.
Room photos from unpaid orders are deleted after seven days. Room photos and their redesigns from paid orders are kept for one year, so you can come back to them, then deleted. Ask us and we delete them sooner.
Domusia Pro listings are deleted with their photos and images one year after the last image staged in them, or thirty days after their creation if nothing was staged. You can delete a listing yourself at any time. Your Pro account, credit history and invoices are kept while the account exists, and invoices as long as accounting law requires.
Three providers, and only what each needs: Supabase stores the data and the images, Google Gemini receives the questionnaire answers to draw the house, and the photo of your room to redesign it, and Stripe handles payment and shows your room photo on the payment page. We do not sell or rent anything to anyone.
You can ask for a copy of your data, have it corrected, or have it deleted. Write to hello@domusia.app and we will answer within a month. If you are in the EU and unhappy with our answer, you can complain to the CNIL.
Every email we send carries an unsubscribe link. One click withdraws your consent: no more offers, reminders or new houses. Unsubscribing does not affect access to houses you have paid for.
