Service providers may process data in countries other than your country of residence. They may also use subprocessors according to their own contractual and legal arrangements.
MEPTools.com is available to users worldwide. Personal data may be transferred to, stored in, or processed in countries other than the country where you live.
These countries may have data protection laws that differ from those in your location. Where required, we rely on appropriate transfer mechanisms, contractual safeguards, provider data processing terms, or other lawful bases for international transfers.
We keep personal data only for as long as reasonably necessary for the purposes described in this Privacy Policy, unless a longer retention period is required or permitted by law.
Our general retention approach is:
| Data category | General retention approach |
|---|---|
| Account data | Retained while your account is active. After account deletion, removed from active systems within a reasonable period unless retention is required for legal, security, billing, dispute, or compliance reasons. |
| Project and engineering data | Retained while stored in your account, unless you delete individual projects, calculations, files, layouts, or exports. |
| Deleted project data | Removed from active systems within a reasonable period. Backup copies may remain until overwritten according to normal backup cycles. |
| Billing, subscription, and transaction records | Retained as needed for accounting, tax, audit, dispute, refund, fraud-prevention, and legal compliance purposes. This may be up to seven years or longer where required by law. |
| Support communications | Retained for a reasonable support, quality, dispute-management, and legal period. |
| Security, diagnostic, and error logs | Retained for a limited operational and security period — generally up to 24 months — unless needed for investigation, abuse prevention, legal claims, or compliance. |
| Analytics data | Retained according to analytics settings and provider controls, and may be aggregated or de-identified for longer-term product analysis. |
| Marketing preferences | Retained until you change your preferences or opt out. We may retain suppression records to avoid sending promotional emails after opt-out. |
When we no longer need personal data, we delete it, anonymize it, aggregate it, or retain it only as required for legal, accounting, security, or operational purposes.
