How We Use Information

We use personal information to:

provide account access, authentication, email verification, and customer support;
create and maintain chats, process uploads, call AI providers, and return outputs;
calculate and deduct credits, process purchases, manage subscriptions, and prevent fraud or abuse;
remember language, session, and other product preferences;
monitor performance, debug errors, analyze traffic, and improve the service; and
comply with legal obligations and protect our rights, users, and systems.

We do not sell your personal information. We may share information with:

AI and infrastructure providers that process prompts, files, or outputs so the service can function. Depending on the model or feature used, this can include third-party inference providers and their upstream model providers.
Storage providers used to store uploaded files and generated assets, such as Cloudflare R2 or S3-compatible storage.
Payment providers used to process purchases and subscriptions, such as Stripe, and any other provider we enable from time to time.
Authentication, email, analytics, and similar providers, such as Google, GitHub, Resend, Google Analytics, Microsoft Clarity, Plausible, OpenPanel, or Vercel Analytics, if enabled on the site.
Legal and safety recipients when disclosure is required by law or reasonably necessary to protect rights, safety, or the integrity of the service.

If you enable web search or submit content that links to third-party resources, your requests may also involve third-party websites or search or information providers.

File Uploads and Sensitive Information

If you upload images or other files, they may be stored in object storage and made available to our service providers by URL so the feature can function. Do not upload highly sensitive personal information, payment card data, government IDs, health records, or other data you do not want processed by third parties.

Data Retention

We retain information for as long as reasonably necessary to operate the service, keep business and billing records, resolve disputes, enforce our agreements, and meet legal obligations. Chat history, uploaded files, and billing records may be retained even after a session ends, subject to our operational needs and legal obligations. If you want to request deletion, contact us at the email below.

Security

We use reasonable administrative, technical, and organizational measures to protect personal information. However, no method of transmission or storage is completely secure, and we cannot guarantee absolute security.

Your Choices and Rights

Depending on where you live, you may have rights to access, correct, delete, or object to certain processing of your personal information. You can also manage some cookies through your browser settings. To make a request, contact us at the email below.
