Privacy Policy

This policy explains what information Crackr collects when you browse the site, create an account, build a project, connect GitHub, run an automated evaluation, or purchase an access pass.

Information we collect

Account information

Clerk provides authentication for Crackr. When you sign in with GitHub, we may receive your name, GitHub username, email address, profile image, and the identifiers needed to connect your Clerk, GitHub, and Crackr accounts.

Project and repository information

We store your project progress and information needed to operate the GitHub workflow. This may include repository identifiers and URLs, branches, commit hashes, push metadata, submission status, and evaluation history.

Code and evaluation data

When you run an automated evaluation, Crackr accesses the selected repository snapshot and executes it in an isolated evaluation environment. We process the submitted code, command output, logs, timing information, and test results needed to run and explain the evaluation.

Do not commit passwords, API keys, private datasets, or other secrets to a project repository. Evaluation output may include text printed by your program.

Payment and access-pass information

Polar processes access-pass purchases. Crackr does not receive your full card details. We may receive your account email, purchased product, payment status, order identifier, and access period so we can grant and manage access.

Usage and device information

We use PostHog, Vercel Analytics, and Ahrefs Analytics to understand how the product and public site are used. Depending on the provider and your settings, this may include page views, product events, referral source, approximate location, browser, device, IP address, and session or cookie identifiers.

How we use information

• Authenticate your account and keep it secure
• Create and connect project repositories
• Track tasks, submissions, and project progress
• Run automated evaluations and return their results
• Process purchases and manage access passes
• Operate, troubleshoot, secure, and improve Crackr
• Send essential account, payment, and service messages

We do not sell your personal information.

Service providers

We share information only as needed to operate Crackr, comply with law, or protect the service. Our main providers include:

• Clerk for authentication and account management
• GitHub for sign-in, repositories, installations, and push events
• Polar for checkout, payment processing, and order events
• Vercel for web hosting and site analytics
• PostHog for product analytics and diagnostics
• Ahrefs for public-site analytics
• DigitalOcean and MongoDB Atlas for application hosting and data storage

Cookies and similar technologies

Clerk uses cookies and tokens required to keep you signed in. Analytics providers may use cookies, local storage, or similar identifiers. You can restrict these through your browser, although blocking required authentication storage may prevent parts of Crackr from working.

Data retention

We retain information for as long as needed to provide the service, maintain legitimate business and security records, meet legal obligations, and resolve disputes. Retention periods vary by data type and provider. We may retain limited records after account deletion when required for security, payment, fraud-prevention, or legal purposes.

Security

We use reasonable technical and organizational safeguards, including isolated evaluation environments and access controls. No online service can guarantee absolute security, so protect your account and do not put secrets in submitted repositories.

Your choices and rights

You may update information through your account and GitHub settings. You may also ask to access, correct, or delete personal information we hold, subject to applicable law and records we must retain. Email us from the address attached to your account so we can verify the request.

Children

Crackr is not directed to children under 13, and we do not knowingly collect personal information from them.

Changes

We may update this policy as Crackr and its providers change. We will update the date at the top and provide additional notice when a change is material.
