Privacy Policy

Last Updated: May 26, 2025

The Simple Version

We collect very little data, we don't sell it to anyone, and we try to keep everything secure. This privacy policy explains exactly what information we collect from users of LeetWho, how we use that information, and what rights you have regarding your personal data.

LeetWho is designed by software engineers who value privacy and understand the importance of protecting user data. We built this platform to help fellow engineers prepare for technical interviews without compromising their privacy or being subjected to invasive tracking practices common in the industry.

What We Collect

Account Information:

When you create an account with LeetWho, we collect the minimum information necessary to provide our service:

Your email address - required to create your account, send you important service updates, and help you recover your account if needed
Password - stored using industry-standard encryption methods. We never store passwords in plain text and cannot see your actual password
Payment information - processed and stored by our payment processor, not directly by us. We only receive confirmation of successful payments
Account preferences - your chosen programming language preferences, display settings, and other customization options

Usage Data:

To provide you with a personalized experience and track your interview preparation progress, we collect:

Questions you've viewed and attempted - helps us show your progress and recommend relevant problems
Your solution attempts and notes - stored securely to help you track your learning journey
Login and session data - timestamps of when you access the platform to maintain security and provide customer support
IP address and basic device information - used for security purposes, preventing abuse, and ensuring proper platform functionality
Platform interaction data - which features you use most to help us improve the user experience

What We Don't Collect

We deliberately avoid collecting personal information that isn't necessary for our service. Here's what we specifically don't collect:

Your real name or personal identification - unless voluntarily provided in your email address, we don't require or store your actual name
Phone numbers or contact information - we only use your email for essential account communications
Precise location data - beyond general geographic information from your IP address, we don't track where you are
Social media profiles or connections - we don't integrate with or collect data from social media platforms
Device fingerprinting or tracking - we don't use advanced tracking technologies to identify your specific device
Browsing history outside our platform - we don't track what you do on other websites
Personal files or documents - we only store what you choose to save in our platform

How We Use Your Data

We use your information solely to provide and improve our interview preparation service. Here's exactly how we use the data we collect:

Platform access - authenticate your account and provide access to interview questions and solutions
Progress tracking - maintain records of your preparation progress, completed questions, and personal notes
Service communications - send essential account updates, security notifications, and occasional service improvements (we keep emails minimal)
Platform maintenance - ensure our servers run smoothly, fix bugs, and maintain service reliability
Security measures - protect your account from unauthorized access and prevent platform abuse
Customer support - respond to your questions and resolve any issues you encounter
Service improvement - understand which features are most helpful to make the platform better for all users

Who We Share With

We share your personal information with a very limited number of trusted service providers, and only when necessary to operate our platform:

Payment processor - we use a secure third-party payment processor to handle billing and subscription management. They receive only the information necessary to process payments
Hosting and infrastructure providers - our servers and database are hosted by reputable cloud service providers who maintain strict security and privacy standards
Email service provider - for sending account-related emails like password resets and important service updates
Nobody else, ever - we do not sell, rent, or share your personal information with advertisers, marketers, data brokers, or any other third parties

All third-party service providers we work with are contractually obligated to protect your data and use it only for the specific services they provide to us.

What We Absolutely Don't Do

Unlike many other platforms, we have made firm commitments about what we will never do with your personal information:

Sell your data to third parties - your personal information is not a commodity to us, and we will never sell it for profit
Share data with advertisers - we don't run ads or work with advertising networks that would want your personal information
Provide information to data brokers - we don't participate in the data broker industry that sells personal information
Use your data for marketing to others - we don't create marketing profiles or use your information to market to other users
Track you across other websites - we don't use cross-site tracking or participate in advertising networks
Create detailed behavioral profiles - we collect only what's necessary for our service, not comprehensive profiles of your online behavior

Data Security

We take data security seriously and implement industry-standard security measures to protect your personal information. While we're software engineers rather than security specialists, we follow established best practices and work with security-focused service providers.

Our security measures include encrypted data transmission, secure password storage using industry-standard hashing, regular security updates, and monitoring for suspicious activities. However, we want to be transparent: no system is 100% secure, and we cannot guarantee absolute security of your data.

If we discover any security breach that affects your personal information, we will notify you promptly and take immediate steps to address the issue. We regularly review and update our security practices to maintain the best protection possible for your data.

Your Privacy Rights

You have several important rights regarding your personal data. We believe in giving you control over your information:

Account deletion - you can permanently delete your account at any time through your settings page, which removes all your personal data from our systems
Data access - you can request to see what personal information we have about you (spoiler: it's not much, just what's visible in your account)
Email preferences - you can opt out of non-essential emails while still receiving important security and account notifications
Data portability - you can export your progress data, notes, and other account information if you want to take it elsewhere
Correction rights - you can update or correct any personal information in your account at any time
Processing limits - you can request that we limit how we process your personal data in certain circumstances

To exercise any of these rights, simply contact us through our contact form or account settings. We'll respond to your request promptly and help you with whatever you need.

Cookies and Tracking

We use essential cookies to keep you logged in and maintain your session security. These are necessary for the platform to function properly. We don't use advertising cookies, tracking pixels, or other invasive tracking technologies.

For detailed information about our cookie usage, please refer to our separate Cookie Policy, which explains exactly what cookies we use and why.

Age Requirements

LeetWho is designed for adult software engineers and computer science students. Our service is not intended for anyone under 18 years of age, and we do not knowingly collect personal information from children under 18. If we discover that we have collected information from a child under 18, we will delete that information immediately.

International Users

Our servers and data processing facilities are located in the United States. By using LeetWho, you acknowledge and agree that your personal information may be transferred to and processed in the United States, which may have different privacy laws than your country of residence.

We take steps to ensure that your personal information receives adequate protection regardless of where it's processed, and we comply with applicable international privacy regulations to the best of our ability.

Policy Changes

We may occasionally update this privacy policy to reflect changes in our practices, legal requirements, or service improvements. When we make significant changes, we'll update the 'Last Updated' date at the top of this page and notify users through email or a prominent notice on our platform.

We encourage you to review this privacy policy periodically to stay informed about how we protect your information. Continued use of LeetWho after changes are posted constitutes your acceptance of the updated policy.

Contact Us

If you have any questions, concerns, or requests regarding this privacy policy or how we handle your personal information, please don't hesitate to contact us. We're committed to addressing your privacy concerns and will respond to legitimate inquiries as quickly as possible.

You can reach us through our contact form or by email. We read and respond to all privacy-related inquiries personally.

Our Commitment to Privacy

LeetWho was built by software engineers who understand the importance of privacy in the digital age. We created this platform to help fellow engineers prepare for technical interviews without sacrificing their personal privacy or being subjected to invasive data collection practices.

Our commitment is simple: collect only what we need, protect what we have, be transparent about our practices, and never use your personal information for anything other than providing you with the best possible interview preparation experience.
