Frequently asked questions
Does PCOcalc suggest an application rate or REI period?
No, never. Federal law (40 CFR 156.10) requires following your product's own label. Every rate and REI value in PCOcalc is one you type in yourself from that label — the app never contains a rate lookup, recommendation, or default for any product.
Does the free tier require an account or an internet connection?
No. The free calculators, unit converter, and 5 saved calculations all work fully offline with no signup of any kind.
What's the difference between individual Pro and PCOcalc for Teams?
Individual Pro is a one-device, one-technician subscription bought in-app — your records stay on your own phone. Teams is a separate, per-business subscription billed on the web that syncs every technician's compliance log into one shared record with an owner dashboard. See Pricing for the full comparison.
How do I cancel my individual subscription?
Individual subscriptions are managed entirely through the App Store or Google Play — cancel there the same way you would any other app subscription. Refunds are handled by Apple/Google, not by us directly.
How do I cancel or change my Team subscription?
Sign in to the web dashboard as the business owner and open Billing — Stripe's hosted billing portal lets you update payment details or cancel directly.
Can a technician delete a compliance record?
No. Once a record is synced to a Team account, only the business owner can delete it — this is enforced in the backend, not just a policy.
Delete your account and data
To permanently delete your PCOcalc account (Team tier) and any data associated only with it — your technician profile, your login, and your compliance record history if you're the sole remaining member — email support@pcocalc.com with the subject "Delete my account" from the email address on your account. We'll confirm your identity and complete the deletion within 30 days.
The individual (free/Pro) tier never creates an account, so there's nothing on our servers to delete — free-tier and Pro calculations and records live only on your own device, and uninstalling the app removes them.
