Hangar Prep is built to run without accounts. The practice tests run in your browser, and your score history is stored only on your own device (local storage) — it never leaves your device and we cannot see it.
Payment is handled by our merchant of record, Lemon Squeezy, which processes your payment details and issues your licence key under its own privacy policy; we receive only what is needed to validate licences. Aggregate, anonymous analytics may be collected to improve the site. We do not sell personal data.

Reviews (optional). If you leave a review we publish your star rating, your comment, the name you choose to give (or Anonymous), the date and the exam page you wrote it from. To show the Verified purchase badge your browser sends the license key it already holds, so our server can confirm the purchase; we store a one-way hash of it, to keep to one review per purchase, and never the license key itself. For reviews from people who have not bought, we keep a one-way hash of your IP address for up to 48 hours to limit spam. To change or remove your review, email [email protected].
