Privacy
Short version: nothing at all unless you sign in, and only what is needed to show you your own progress if you do.
Without an account
Every drill works signed out. Your answers, streaks and flagged themes are written to your browser’s local storage on your own device and are never sent anywhere. No account, no cookie for tracking, no analytics script.
Clearing your browser data deletes all of it, and nobody, including us, has a copy.
With an account
Your name and email
Supplied by Google when you choose to sign in. Used to identify your account and show who is signed in. Never sold, never shared, never emailed to you for marketing.
Your profile picture
A URL from your Google account, used only to render the avatar in the header.
Which questions you answered
The question, whether you got it right, its topic, and when. This is what the progress page is built from.
Interview answers you have marked
The transcript of each marked station, its feedback, and timing numbers such as words per minute. Kept so you can reread feedback and so the marking allowance can be counted. Audio is never uploaded.
A session cookie
Needed to keep you signed in. It is not used for advertising or tracking across other sites.
Data is held in a Postgres database hosted by Neon, and the site runs on Vercel. Both act as processors and can see the data only as part of hosting it.
Interview practice
Speech is turned into text inside your browser by a speech model that downloads once from Hugging Face. The audio itself is never uploaded. A recording is kept in the page so you can listen back, and it is gone when you leave the page.
When an answer is marked, the station and your transcript are sent to an AI model that writes the feedback. Normally that is an open model run by Cloudflare (Workers AI), which does not keep the text or use it to train models. If Cloudflare is unavailable, a backup is Anthropic’s Claude, which under Anthropic’s commercial terms does not train its models on this data by default. Both act as processors. Practising without marking sends nothing anywhere.
Control
Reset progress. Every drill has a Reset button, which clears that section for your account and on your device.
Delete the account. Email hello@lazygamsat.com and everything tied to it, including every answer, is deleted. No retention period and no backups kept beyond the hosting provider’s own rolling window.
Ask what is held. Same address, and you will get the lot in a readable file.
There is no third-party analytics, no advertising network, no tracking pixel, and nothing is sold or shared. If that ever changes, this page changes first.
