Optional, always
You don’t need an account.
Every ChemEase tool works without signing in, and what you do stays on the device you did it on. Signing in with Google only personalises the app — it is not a condition of using anything.
Nothing is uploaded
Your calculations, notebook entries and saved structures are held in your own browser. There is no ChemEase server keeping a copy.
Works with no signal
Because everything runs locally, the tools keep working in a basement lab with no reception. The Android app behaves the same way.
What signing in does
ChemEase shows your Google name and picture instead of a generic profile. That is the whole of it, and it applies to that one device.
Ready when you are
The tools are open to everyone. Start using ChemEase now — there is no step in between.
Open ChemEaseSign-in lives inside the app, so there is only ever one place it can happen. Open ChemEase, go to Settings, and choose:
Google gives ChemEase your name, email address and profile picture. They are stored on your device and sent nowhere else. Signing out clears them.
By using ChemEase you agree to the Terms and Privacy Policy.
