The dbml does not persist across multiple devices even with the same account logged in

Thanks for the kind words — we really appreciate it! 🙏

The behavior you noticed is actually by design. DatabaseDiagram is built with a privacy-first approach — we don’t store any of your DBML or diagram data on our servers. Everything is rendered and saved locally in your browser to ensure your content stays private and secure.

The login account is mainly used for community discussions and to manage paid subscriptions, not for syncing user-entered content.

This design keeps your data completely under your control — nothing leaves your device. 💪
