AviaTests privacy policy.

This page keeps AviaTests privacy information in one place for account, billing, study, technical, and usage data questions.

Account and contact details you provide, such as name, email address, and authentication information.
Billing and purchase records needed to confirm access, process payments, and handle refund or support requests.
Study activity, such as chosen subjects, sessions, answers, progress signals, and support conversations you start.
Technical and usage data like browser, device, IP-derived security signals, and product interaction events.

To create and protect accounts, deliver study access, and keep core features working.
To personalize your experience, show progress, answer support requests, and investigate product issues or abuse.
To process billing, calculate refunds, and understand how AviaTests performs so the product can improve over time.

AviaTests may share data with service providers that help run the product, such as hosting, payments, email delivery, support tooling, or analytics providers.
Those providers should only receive what is needed for their role and should process that data on AviaTests behalf.
AviaTests does not sell personal data. Information may still be shared when required by law, to protect the service, or as part of a legitimate business transfer.

AviaTests keeps data for as long as it is reasonably needed to operate the service, meet legal obligations, resolve disputes, and maintain accurate records.
Reasonable technical and organizational safeguards are used, but no online system can promise perfect security.
To request access, correction, deletion, export, or other privacy help, email hello@aviatests.com from the account you want reviewed so identity can be verified before action is taken.
