Frequently Asked Questions

Rentool

How do I list a tool for rent?
Create an account, tap "List a Tool," add photos and details, set your price, and publish.

How are payments handled?
Payments are processed securely through the app. Owners receive payouts after the rental period ends.

What if something gets damaged?
Contact the other party through the app first. If you can't resolve it, reach out to our support team.

FlightDose

How accurate are the radiation estimates?
Estimates are based on established atmospheric radiation models. They are intended for informational purposes and may vary from actual exposure.

Does FlightDose work offline?
You need an internet connection to fetch flight and radiation data. Previously viewed flights are cached for offline access.

MySievert

Where do the dose values come from?
Published reference sources such as ICRP, NCRP and FDA labels; each record shows its own citation. They are typical values, not your measurement. Informational only, not medical advice. Ask your physician about your own numbers.

Can you recover my history if I lose my phone?
Only if you set up a recovery code or a backup first. Records are encrypted with a key that never leaves your devices, so we cannot read or restore them for you.

ApexPoster

How do I connect a screen?
Install ApexPoster on your Fire TV or Android TV device, then pair it to your account using the code shown on screen.

How much does it cost?
ApexPoster is free on one screen, forever. Reach out if you need to run additional screens.

General

How do I delete my account?
Email support@apextechnologygroup.io with your account details and we'll process the deletion.
