Every dataset is labeled measured, literature or virtual. Virtual data is used only for demonstration.
License
The default license is CC BY 4.0: anyone may use it with attribution.
Review
New data starts as 'not yet reviewed' and goes through format, source and scientific review separately.
AI
All AI outputs are labeled and never replace researchers' judgment. Demo responses are marked 'AI demo'.
Privacy
We collect only a display name and contact. Under-14s need guardian consent.
Environmental safety
Lab results are not applied directly to real rivers, lakes or seas; separate safety validation is required.
Storage
Measured and literature data registered by signed-in researchers with a verified email are stored in the server database. Edits and withdrawals are kept in the record with their reasons, never erased. Virtual data is not stored on the server.
