Privacy
My account
Member accounts store the username, administrator-entered name, email and company, a password hash, account status and last sign-in time. Sign-in uses an essential session cookie lasting up to 8 hours. The administrator can update or delete accounts. The audit log retains the action, timestamp and numeric account ID. Contact us about deletion and backup retention. Google Analytics and AdSense code is not loaded on sign-in or member pages. The quota covers original .DDD files. Files and their derived activity data are removed by daily cleanup after 18 calendar months from upload. Uploading the same file again does not extend retention. Server backups follow a separate policy.
IP · Privacy
Public-page visitor statistics use separate daily, monthly and yearly HMAC pseudonyms of IP addresses. The statistics table does not store raw IP addresses. Pseudonyms are retained for the current and two previous calendar years. Counts use Europe/Vilnius time, without cookies or uploaded DDD data.

Google Analytics is used with consent to measure visits to public information pages. It is not loaded on analysis or administration pages. Your choice is remembered for 180 days and can be changed using Analytics preferences. Analytics cookies can last up to 180 days. Withdrawing consent deletes this integration’s cookies. Advertising consent is managed separately.
