Last Updated: February 5, 2026

Introduction

Welcome to Rival ("rival.tips"). We are committed to protecting your personal information and your right to privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you visit our website and use our services, including when you create an account, subscribe to Pro features, generate AI challenges, purchase datasets, or use our model sponsorship program.

If you have any questions or concerns about this privacy notice or our practices, please contact us.

Information We Collect

We collect information in the following ways:

Information You Provide to Us

Account Information: When you register for an account, we collect personal information such as your email address. If you register using a third-party provider like Google or GitHub, we may receive your name and avatar URL as provided by that service.
Subscription & Payment Information: If you subscribe to our Pro tiers, purchase datasets, or enroll in our model sponsorship program, our payment processor (Lemon Squeezy) will collect payment information necessary to process the transaction. We receive confirmation of payment and subscription status, but we do not directly store your full payment card details. We store your customer ID and subscription ID to manage your account.
User-Generated Content: If you are a Pro user, we collect the prompts you submit when creating challenges. The AI-generated responses to these prompts are also stored.
Dataset Purchases: When you purchase the Rival Datasets product, we collect your email address and payment information via Lemon Squeezy to process and fulfill the order. We retain a record of your purchase for license verification and customer support.
Sponsorship Information: If you enroll in our model sponsorship program, we collect your email address, name or company name, and selected model preferences via Lemon Squeezy. This information is used to activate and manage your sponsorship placement.
Newsletter Subscriptions: If you sign up for our newsletter or product updates, we collect your email address and capture your explicit consent. We also record limited context about the subscription event, including the date/time, source, your IP address and user agent (for security, abuse prevention, and compliance), and a versioned consent statement.
Voting & Interaction Data: When you vote in AI duels or model comparisons, we record your vote along with a session identifier. This data is used to generate community rankings and is included in aggregated, anonymized form in the Rival Datasets.
Communications: If you contact us directly, we may receive additional information about you such as your name, email address, the contents of the message, and any other information you may choose to provide.

When you use our Website, we automatically collect certain information about your device and usage:

Cookies and Similar Technologies: We use cookies and similar tracking technologies (like web beacons and pixels) to access or store information, operate the service (e.g., authentication), and analyze usage. You can control the use of cookies at the individual browser level.
Analytics Data (PostHog): We use PostHog for web analytics to understand user behavior and improve the service. This data includes interactions with site features and may be linked to an anonymous or user ID. You can learn more about PostHog's privacy practices on their website.

To understand and analyze how you use our Website and Services (via analytics).
To process your transactions, manage subscriptions, fulfill dataset purchases, and manage sponsorship placements (via Lemon Squeezy).

How We Share Your Information

We may share the information we collect in the following circumstances:

Service Providers: We share information with third-party vendors that perform services on our behalf, such as payment processing (Lemon Squeezy), cloud hosting (Vercel, Supabase), AI model access (OpenRouter), task queueing (Upstash/QStash), and analytics (PostHog). If we use an email delivery provider to send newsletters, your email address may be processed by that provider solely to deliver and manage the emails. These providers only have access to the information necessary to perform their functions.
AI Models (OpenRouter): When Pro users create challenges, the submitted prompts are sent to the selected AI models via the OpenRouter API to generate responses. Please refer to OpenRouter's policies regarding data handling.
Business Transfers: Information may be disclosed or transferred as part of, or during negotiations of, any merger, sale of company assets, financing, or acquisition of all or a portion of our business to another company.
Legal Requirements: We may disclose your information if required to do so by law or in the good faith belief that such action is necessary to comply with a legal obligation, protect and defend our rights or property, prevent or investigate possible wrongdoing, protect the personal safety of users or the public, or protect against legal liability.
With Your Consent: We may share your information for other purposes with your explicit consent.

We do not sell your personal information.

Affiliate Links & Sponsored Content

Our Website contains affiliate links and sponsored content placements. When you click on an affiliate link (such as links to ElevenLabs, Cursor, OpenRouter, and other developer tools), you may be directed to a third-party website. If you make a purchase through these links, we may receive a referral commission at no additional cost to you.

Affiliate links are identified with rel="sponsored" attributes. The inclusion of affiliate links does not influence our editorial content, model rankings, or comparison results. Model sponsorship badges are clearly labeled and do not affect duel outcomes or community vote tallies.

Rival Datasets

The Rival Datasets product contains pre-generated AI model responses to standardized prompts and aggregated, anonymized community voting statistics. The datasets do not contain any personally identifiable information. Individual votes are aggregated into win rates and statistical scores before inclusion.

Data Storage and Security

Your information, including profile data, user-generated challenges, and responses, is stored using Supabase. Payment data is processed and stored by Lemon Squeezy according to their security standards. We implement reasonable security measures to protect your information. However, no electronic transmission or storage is 100% secure, and we cannot guarantee absolute security.

Newsletter Data

Newsletter subscription records are stored in Supabase and include your email address, consent status, subscription timestamp, source, and technical metadata (IP address and user agent). This information is used to validate consent, prevent abuse, and comply with applicable regulations. We do not sell your information.

You can unsubscribe at any time via the link in any newsletter email or by contacting us. Unsubscribing will stop further emails; you may separately request deletion of your subscription record.

Data Retention

We retain your personal information for as long as your account is active or as needed to provide you services, comply with our legal obligations, resolve disputes, and enforce our agreements. User-generated challenges and responses are retained until the user deletes them or their account, subject to our backup policies.

Newsletter subscription data is retained until you unsubscribe or request deletion, or as required to demonstrate consent and compliance under applicable law.

Dataset purchase records and sponsorship records are retained for as long as needed to provide the purchased service, fulfill licensing obligations, and comply with financial record-keeping requirements.

Your Privacy Rights

Depending on your location, you may have certain rights regarding your personal information:

Access: You can request access to the personal information we hold about you via your account settings or by contacting us.
Correction: You can update your account information through your account settings.
Deletion: You can request the deletion of your account and associated personal data via your account settings or by contacting us. Note that deleting your account will also delete your user-generated challenges and responses.
Opt-out of Marketing: You can opt-out of receiving promotional communications by following the unsubscribe link in any email we send.

Users in certain regions (like the EEA, UK, Canada) may have additional rights under applicable data protection laws.

Legal Bases for Processing (EEA/UK)

Consent: We process your email address and related metadata to send newsletters only where you have provided clear consent.
Contract: We process payment and account data as necessary to fulfill subscriptions, dataset purchases, and sponsorship agreements.
Legitimate Interests: We may process technical data (e.g., logs) for security, fraud prevention, and service operations.

Third-Party Websites

Our Website contains links to other websites not operated by us, including affiliate partner websites, model provider websites, and payment processor websites. This Privacy Policy does not apply to third-party websites. We encourage you to review the privacy policies of any third-party website you visit.
