Support

Email solvella-support@googlegroups.com. We usually reply within one business day (Brisbane time, UTC+10).

What to include

• What you were doing: the tool (Goal Seek, Solver or Data Analysis) and the button you pressed.
• The message Solvella showed, copied exactly or as a screenshot.
• For Solver: the objective, the variable cells and the constraints, or a copy of the sheet with the numbers changed if they're private.
• For licence questions: the email address you paid with. Please don't send your card details.

Common requests

I lost my licence key

Email us from the address you paid with and we'll send it again.

"This licence key is in use on another account"

Each key works on one Google account. If the other account is yours, press Move licence to this account in Account & upgrade. You can move it once every 30 days; ask us if you need it sooner.

"We couldn't tell which Google account you're signed in with"

This happens when several Google accounts are signed in to the same browser. Open the spreadsheet in a window signed in to only one account (a private window works) and try again.

Refunds and cancellations

See the refund policy. To cancel a subscription, use the link in your Stripe receipt or email us.

Something gives a different answer from Excel

Send us both results and the data. Nonlinear Solver can find a different local optimum from a different starting point; for everything else a different answer is a bug we want to fix.
