Privacy policy
Version 1 of 11/10/2026
Kvadrino is an app for working out building materials and writing estimates. This policy explains what the app keeps, what it sends to us and what you can do about it.
Contact for data questions: support@kvadrino.com
What stays on your device only
Everything you enter stays on your phone or computer and never reaches us:
- jobs, rooms, sizes, calculations, estimates and their versions, shopping lists;
- your rates, business details and logo;
- your customers’ details: names, phones, addresses.
We don’t see this data and can’t read it. A backup is a file you save yourself and keep wherever you choose.
The PDF of an estimate is made on the device. You send it yourself, through an app you choose, such as a messenger or e-mail. We don’t receive it.
What the app sends to us
Updates of material sets. Once a day the app asks kvadrino.com whether new sizes and norms for your region are out, and downloads only what changed. As with any website, our server sees the IP address and the type of device. These are not linked to you and are used only to run and protect the server.
Crash reports and anonymous events. To find and fix errors, the app sends:
- what happened (a crash or an event) and where in the program;
- the error message, with every number and e-mail address hidden;
- the version of the app and the system, the language, the country;
- a random installation number made on the phone.
The reports contain no sizes, sums, names, phones, addresses and not your IP address. They are kept for 90 days, then deleted. You can turn them off in More → Settings.
What the app doesn’t have
- ads or third-party analytics;
- selling or passing data to anyone;
- accounts: the app works without signing up.
When signing in and sync between devices arrive, we will update this policy before they are switched on. You will see the new edition on this page.
Your rights
You can ask what data about you we hold and ask us to delete it: write to support@kvadrino.com. The data on your device is deleted with the app. A deleted job with its estimates stays in the bin for 30 days, then is deleted for good; you can also delete it from the bin at once.
Children
The app is made for adult professionals and is not meant for children.
Changes
New editions are published on this page with their date. If a change matters, the app will tell you.
