Security and data
Your stock, costs, orders and customers are your business. Here is where they are kept, who can see them, how they come back if something breaks and how you take them with you, including what we do not do yet.
Every new account starts with 14 days of PRO, no credit card. The FARM plans have their own 14-day trial: a card is required and nothing is charged during the trial.

Prusa (PrusaLink) and Klipper (Moonraker) printers are read by 3DPM Agent on your local network, without a cloud. The data flows one way, into 3D Print Manager: neither the Agent nor Home Assistant lets 3DPM start, stop or send a print.
The service runs over HTTPS (TLS), and http:// redirects to https://. Session cookies are Secure and HttpOnly: they travel only over HTTPS and page scripts cannot read them.
Stored only as a one-way hash (PHP password_hash), so nobody can read them back, including us. A "remember me" sign-in lasts at most 30 days.
Every query is limited to the account the data belongs to, and automated tests try to reach another account's data before every release.
Owner, manager, operator and viewer. A viewer can only read, and permissions are checked on the server. An invitation link is valid for 14 days.
Only the owner of dD Tech, bound by confidentiality, has access to the server and the database.
Old print history is trimmed only after a nightly backup has succeeded, so a failed backup never removes anything.
What we don't do yet. There is no two-factor sign-in. The database and the backups are not encrypted separately at rest: they are protected by the hosting account and are never served to the internet. We hold no security certification of our own, and we don't claim one.
Your inventory exports to CSV at any time, on every plan: Settings → Import / Export. Customer and order data comes in a machine-readable format within 30 days of a request to info@ddtech.hr.
The account owner deletes the account in Settings → Danger Zone, and an active subscription is cancelled with it. The data, PDF quotes and invoices included, is deleted at once and is gone from the backups within 14 days.
Finished print jobs are kept for 90 days, usage history for 400 days and team activity for 90 days; older records are deleted on their own.
Invoices and other records the law makes us keep stay for the statutory period after deletion (Privacy Policy).
