1 · Using Mycrometer
You may use Mycrometer free of charge, for any purpose, including identification, recording, research, teaching and publishing your results. Your photos, measurements and files are yours. Mycrometer runs on your own device and doesn’t send them anywhere.
2 · What isn’t allowed without written permission
- copying, re-hosting or redistributing Mycrometer’s code, or offering it from another website or app;
- modifying it, or building other software from it;
- selling it, or including it in anything that’s sold.
To ask, write to hello@mycrometer.app.
3 · No warranty
Mycrometer is provided as-is, with no warranty of any kind, and no guarantee that its measurements are fit for any particular purpose. It hasn’t been validated against a certified reference instrument or independently peer-reviewed. Calibration, camera setup and technique are in your hands. A mistake in any of them gives wrong numbers that still look plausible. Check results against what you know about the material, and don’t rely on them alone where accuracy matters. As far as the law allows, Field Mycologist UK isn’t liable for any loss arising from using Mycrometer.
