Privacy Policy
Effective June 28, 2026 · KTLYST Labs, San Jose, California
We do not collect, store, log, or sell any of your data. There is no server, no database, no account, no analytics, and no tracking cookies. Everything you type stays in your browser. The only thing that ever leaves your device is your interview conversation, which your browser sends directly to Anthropic using your own API key. We never see it.
Who we are
This app ("Interview Coach") is operated by KTLYST Labs, based in San Jose, California, USA. You can reach us at crew@ktlystlabs.com.
What we collect
Nothing. We do not collect any personal information. We have no server that receives your data, no database, no user accounts, no analytics or telemetry, and no advertising or tracking cookies. The app is a static website that runs entirely in your browser.
What is stored on your device
To make the app work, your browser saves the following in its own local storage, on your device only: your Anthropic API key, your current interview conversation, the role profile and weak spots the coach remembers, and your settings. This never leaves your browser and is never sent to us. You can erase all of it at any time by clearing this site's data in your browser, or by starting a new interview.
What leaves your device, and to whom
Two things involve parties other than you, and we want to be precise rather than overclaim:
Anthropic. When you run an interview, your browser sends your messages and your API key directly to Anthropic to generate the coaching, under your own Anthropic account. We are not in the middle and never receive this. Anthropic's handling of that data is governed by their own terms and policy: anthropic.com/legal/privacy.
Our hosting provider (Vercel). The page itself is served by Vercel. Like any web host, Vercel may automatically process standard technical request information such as your IP address and browser type in order to deliver and secure the site. We do not access or use this for tracking, advertising, or profiling. See Vercel's privacy policy.
Cookies and tracking
We use no tracking cookies and no analytics. The app uses your browser's local storage strictly to function (the items listed above), not to track you across sites or sessions.
Your choices and rights
Because we hold no data about you, there is nothing on our side to access, correct, delete, or export. You are always in full control: clear your browser's storage for this site to remove everything instantly.
We do not and will not sell or share your personal information, and we have no information to sell. If you are a California resident, this is also our notice under the California Consumer Privacy Act (as amended by the CPRA): the categories of personal information we collect is none, and we do not sell or share personal information. Residents of other regions with similar laws (such as the EU/UK GDPR) have the corresponding rights; since we hold no personal data, there is nothing for us to act on, but you may contact us with any question.
Children
This app is not directed to children and is intended for adults preparing for job interviews.
Not professional advice
The coaching is practice feedback generated by an AI model. It is provided as is, without warranty, and is not professional, career, legal, or employment advice, and does not guarantee any interview or hiring outcome.
Changes
If we change this policy, we will update the effective date above. Material changes will be reflected on this page.
