Privacy Policy

• Account information: your e-mail address and name, and if you sign in with Google, the basic profile Google shares with us.
• What you do on Katkat: questions you save or mark done, code you run or submit and its results, AI mentor conversations, whiteboard drawings, and answers or comments you post.
• Interview plans: the companies you tell us you are interviewing with, which we use to recommend questions.
• Billing information: purchase and membership status. Card details are collected and stored by Stripe; we never see or store your full card number.
• Usage and device data: pages you visit, timestamps, IP address, browser and device type, referral links you used, and error logs.
• Messages you send us.

We do not sell your personal information.

• to provide the Service: your progress, the code runner and judge, the AI mentor and community features;
• to run your account and membership and process payments;
• to send service e-mails (account, receipts, important changes) and answer support requests;
• to keep the Service secure and prevent abuse, fraud and payment disputes;
• to understand how the Service is used and improve it, mostly in aggregate.

We share data only with service providers that help us run the Service, under contracts that limit their use of it:

• AI model providers (such as OpenAI, Google Gemini and Anthropic), which receive your AI mentor messages and the question context;
• Stripe, for payments;
• Google, when you choose Google sign-in, and Google Analytics, for aggregate usage statistics;
• hosting providers, and Resend for sending e-mail.

Answers and comments you post are public and shown with your display name. Do not include personal information you do not want others to see.

We may disclose information if required by law or a valid legal request, to enforce our terms, or to protect the rights, safety and property of our users, the public or us. If our business is sold or merged, data may transfer to the new owner under this policy.

We use cookies and local storage to keep you signed in, remember your code drafts and preferences, and measure usage (Google Analytics). We also set a random, anonymous visitor ID cookie (kk_vid) so we can count visits and which questions are read, including by people who are not signed in; it is not linked to your IP address or browser details, and is linked to your account only if you sign in. You can block or delete cookies in your browser; staying signed in will not work without them.

We keep your data while your account is active. When you ask us to delete your account, we delete or anonymise your personal data within 30 days, except records we must keep for legal, tax, accounting or dispute purposes (such as payment records). Content you posted may be removed or anonymised.

You can ask us for a copy of your personal data, or to correct or delete it, by e-mailing [email protected]. Depending on where you live (for example California, the EU or the UK), you may have additional rights under local law, including the right to complain to a data protection authority. We will not treat you differently for exercising these rights.

We use encryption in transit (HTTPS), hashed passwords, access controls and an isolated sandbox for running code. No system is perfectly secure; tell us at [email protected] if you notice anything suspicious.

We are based in the United States and our providers may process data in the US and other countries. Where required, we rely on appropriate safeguards for these transfers.

The Service is not directed at children under 13, and we do not knowingly collect their personal information. If you believe a child has given us data, contact us and we will delete it.

We may update this policy and will change the date above when we do; material changes will be announced on the site or by e-mail. Questions or requests: Parko Tech, Inc., [email protected].
