NIMDEE Civil and Infrastructure Limited ("NIMDEE", "we"), [REGISTERED BUSINESS ADDRESS], is responsible for the personal data described here. This policy explains what we collect when you use the NIMDEE website (nimdeelimited.com), the NIMDEE licence service and the NIMDEE Structural Rebar Suite add-in for Revit, why, and your rights. Questions: support@nimdeelimited.com.
1. What we collect
| Data | Why |
|---|---|
| Name, e-mail address | Your account, signing in, licence and billing e-mails. |
| Password | Signing in. We store only a strong one-way hash (Argon2id), never the password itself. |
| Computer identifier: a one-way hash made from your Windows installation id and system drive serial number | Limiting each seat to one computer and the free trial to one per computer. We cannot work back from it to the original ids. |
| Computer name (as set in Windows), add-in version, sign-in and last-seen times | Showing you which computers are signed in, so you can free one; support. |
| Licence and subscription details: plan, seats, dates, status, the people on an Enterprise licence (their e-mail addresses) | Providing the plan you chose. |
| Payment records from Paystack: references, amounts, dates, Paystack customer and subscription codes | Linking payments to licences, renewals, refunds, accounting. |
| Technical data: IP address and request details | Security, preventing abuse (rate limits) and fixing faults. Kept in short-lived server logs, not in our database. |
What we do not collect: your Revit models, drawings or project data (the add-in works on them on your computer only), and your card or mobile money details (entered on Paystack's pages, never sent to us).
2. Legal bases
We use this data to perform our contract with you (account, licence, billing), to meet legal obligations (for example accounting records), and for our legitimate interests in keeping the Service secure and preventing licence sharing and fraud. Where the law requires consent, we ask for it.
3. Who we share it with
We do not sell personal data. We share it only with service providers who process it for us under contract:
- Paystack: payments and subscriptions;
- Render: hosting of our servers and database (in the European Union, Frankfurt);
- [E-MAIL PROVIDER]: sending account e-mails;
and with authorities where the law requires it. On an Enterprise licence, the owner sees the e-mail addresses of the people on the licence and the names of their signed-in computers.
4. International transfers
Our servers are in the European Union, so your data is transferred outside [Ghana]. Our providers protect it with contractual and security measures that the law requires.
5. How long we keep it
- Account and licence data: while your account is open, and up to 12 months after it is closed (for support and to prevent repeated free trials).
- Payment records: as long as accounting and tax law requires (usually [6] years).
- Server logs: up to 30 days.
- Sign-in sessions end after 30 days without use; e-mail confirmation and password reset links expire after 48 hours and 1 hour.
6. Security
All traffic is encrypted (HTTPS). Passwords, computer identifiers and sign-in tokens are stored only as one-way hashes. On your computer, the add-in keeps its sign-in encrypted with Windows' own per-user protection. Access to our systems is restricted to the people who need it.
7. Cookies and storage
The NIMDEE website uses no cookies, advertising or tracking. When you sign in to the website, your browser stores a sign-in token for up to one hour (local storage), removed when you sign out.
8. Your rights
You may ask us for a copy of your personal data, to correct it, to delete it (where we do not need to keep it by law), to restrict or object to its use, and to receive it in a portable form. Write to support@nimdeelimited.com; we answer within 30 days. You may also complain to the data protection authority, [the Data Protection Commission of Ghana].
9. Children
The Service is for professionals and is not meant for anyone under 18.
10. Changes
We will post any change here with a new date, and e-mail you about important changes.
