Questions
Is Onevia free?
Yes. The tools available today are free to use. Any future paid plan will be clearly labeled before you're asked to pay.
Where is my data stored?
Right now, your work is saved in this browser on this device. Accounts with cloud sync are on the roadmap.
Are the results financial advice?
No. Calculations use standard formulas and your inputs, and every estimate is labeled. They help you plan — they don't replace a professional.
Are tax figures exact?
The paycheck calculator uses 2025 federal and state rules for all 50 states, but it is an estimate — local taxes and credits are not included.
