Privacy policy

Who we are

Chessosaurus is made by Cumbernauld Software Solutions Ltd (“we”), a private limited company registered in Scotland, company number SC717373. Registered office: 26 Wellesley Drive, Cumbernauld, Glasgow, G68 9PG, Scotland. For any privacy question, email privacy@cumbernauldsoftwaresolutions.com.

What stays on the device

The app never asks for a name: each player is simply their favourite dinosaur. Favourite dinosaurs, progress, stars, stickers, settings and saved games are kept only on the device. We never receive them. They are not included in phone backups and do not move to a new phone. Deleting the app deletes them.

What we collect

Nothing, unless a grown-up switches on error reports (see below). The app has:

• no accounts or sign-in, and it never asks for a name, email address or phone number;
• no adverts and no advertising identifiers;
• no analytics, tracking or crash-reporting services from other companies;
• no chat, and no way for children to send messages or share personal information;
• no location access.

Optional error reports

Error reports are off unless a grown-up switches them on, behind the grown-up check, and the internet setting is also on. When switched on, one report is sent the next time something goes wrong, and error reports then switch themselves off again.

Reports are stored in Google Cloud Firestore, which we use only to receive them, and are deleted after 30 days. While the internet is off, a report waits on the device and is deleted after 7 days if it can't be sent. Switching error reports off deletes any report still waiting.

Like any message sent over the internet, a report arrives from the network address of the connection it was sent from. We don't add that address to the report and we don't keep it; Google, which runs the servers, handles connection information under its own policies.

Playing on two devices

Two nearby devices can be paired for a game. A grown-up scans a code shown on one device with the camera of the other. The camera only reads that code, on the device: no picture is taken, kept or sent. Once paired, only chess moves are exchanged, encrypted, directly between the two devices over local Wi-Fi or Bluetooth. Nothing goes through our servers or the internet. A grown-up can switch two-device play off.

Permissions the app uses

Links and sharing

Web links and sharing are behind the grown-up check. If a grown-up opens a link, it opens outside the app, and that website's own privacy policy applies.

Children's privacy

Chessosaurus is designed for children, with the UK Age Appropriate Design Code (Children's Code), the UK GDPR, the US Children's Online Privacy Protection Act (COPPA) and Google Play's Families policy in mind. Because we collect no personal information from children, there is nothing for us to share, sell or use for advertising.

Your rights

You can ask us about anything in this policy, or ask us to delete an error report, by emailing privacy@cumbernauldsoftwaresolutions.com. Reports cannot be linked to a person, so please tell us roughly when it was sent and on which phone model. You can also complain to the UK Information Commissioner's Office at ico.org.uk.

This website

This website uses no cookies, no analytics and no tracking, and loads nothing from other websites. It is hosted on GitHub Pages; GitHub may keep standard server logs, including visitors' network addresses, for security, under its own privacy statement.

Changes

If we change this policy, we will update this page and the date at the top. We will never start collecting personal information from children.
