What the software sends, and why
| Data | When | Purpose |
|---|---|---|
| Installation ID (random), device token (random secret), one-way machine fingerprint (SHA-256 hash of hardware identifiers — the identifiers themselves are not sent), computer name, application version | Every licence check (at start and periodically while the app runs) | Confirm the licence, the authorised computer and the enabled tools; prevent licence sharing |
| Name, e-mail address, company | When you request a trial, a commercial licence or a licence move | Identify the customer, approve and administer the licence, contact you about it |
| Trial survey answers | Only if you complete the optional survey | Improve the product; decide trial extensions |
| Tool usage counts: per day, tool, program (SAP2000/ETABS), edition (EXE/plugin) and version — how many times each tool was opened, completed, cancelled or failed | With the licence check, unless you switch off Share anonymous usage statistics in the Help & Licence menu (on by default) | Improve the tools, fix the ones that fail, decide what to develop next |
| IP address | Every request to the licence server | Rate limiting and abuse protection; counters are deleted after 24 hours |
| Security/audit records (licence events, approvals, delivery of notification e-mails) | Licence administration | Security, dispute resolution, accounting |
Usage counts never include model data, file names, dimensions or results. Switching sharing off deletes the counts not yet sent from your computer.
The software does not send your SAP2000/ETABS models, model data, results, file names or diagnostic logs. Logs and run reports stay on your computer (%LocalAppData%\NCSE\logs) unless you choose to e-mail them to us.
Lawful basis
Performance of the licence agreement (licence checks and administration), our legitimate interest in protecting the software against unauthorised use and abuse, your consent for the optional survey, and our legitimate interest in improving the software for the usage counts (you can object at any time by switching them off).
Where the data is stored
The licence service runs on Cloudflare Workers with a Cloudflare D1 database. Licence notification e-mails to NCSE are delivered through Resend. The website uses Cloudflare Web Analytics (no cookies, no cross-site tracking). These providers may process data outside the UAE under their own data-protection terms.
How long we keep it
Licence, device and customer records: for the duration of the licence and up to 24 months after it ends (longer only where accounting law requires). Rejected or abandoned requests: 12 months. Survey answers and usage counts: 24 months. Rate-limit counters: 24 hours.
Your rights
You can ask for access to, correction or deletion of your personal data, object to processing, or withdraw consent for the survey, by e-mail to ncse2000@gmail.com. Deleting licence records ends the licence on that computer. You may also complain to your data-protection authority (in the UAE, under Federal Decree-Law No. 45 of 2021; in the EU/UK, your local supervisory authority).
Changes
We will publish any change on this page with a new effective date.
