Privacy notice

What the RKad app and server collect, why, where it is stored and for how long.

Users in Türkiye can read the formal notice under the KVKK in Turkish: KVKK aydınlatma metni.

Who we are

RKad is built and run by Rıfat Kaşıkcı, Dokuz Eylül University, Faculty of Engineering, Tınaztepe Campus, 35390 Buca, İzmir, Türkiye, privacy@rkad.app. The CAD and OpenRocket files belong to the team that uploads them; RKad stores them on the team's behalf.

What we collect

DataSourcePurpose
Name, role, team; email if you add oneYou and the captain who invited youYour account; showing the team who did what
A hash of your sign-in tokenThe appSessions. The token itself stays on your computer, in Windows Credential Manager
Locks: person, computer name, timeThe appShowing who is editing a part, and on which machine
Versions: author, note, date, filesYouVersion history
Usage events: screens opened, actions and their duration, errors, app version, the computer's memory, CPU and disk useThe appImproving the product, finding problems, statistics for the team and the operator
Error reports: error type and message, stack trace, screenThe app and the serverFixing bugs

Usage events and error reports identify people by id only; names are never written to them. The Windows account name and profile path are removed from error texts before they are sent. File contents and free text (searches, notes) never enter usage events. IP addresses are not stored: they are held only in the server's memory to limit abuse and cleared when it restarts (at least daily). Our hosting providers (Heroku, Cloudflare) keep their own short-lived access logs, which include IP addresses.

This website sets no cookies and runs no analytics or trackers.

Why

To provide the service you signed up for (account, locks, versions), and our legitimate interest in keeping it secure, fixing errors and understanding how it is used. We don't sell data or share it beyond the providers below. Your team's owners and captains can see their own team's usage statistics.
