Privacy Policy

Ler E Aprender ("we", "us", "our") operates the website www.lereaprender.com. This Privacy Policy explains how we collect, use, and protect your personal information when you use our service.

• Account information — email address and a securely hashed password when you register.
• Uploaded content — book page images you upload for OCR processing and translation.
• Learning data — your language preferences, CEFR level, and generated translations, phrases, and grammar notes.
• Usage data — pages visited, feature interactions, and technical information such as browser type and device, collected via analytics.

We use Google Tag Manager (GTM) to load analytics scripts that help us understand how the site is used. These tools may set cookies on your device. Cookies are small text files stored by your browser. You can disable cookies in your browser settings, though some features may not function correctly without them.

• To provide, maintain, and improve our service.
• To authenticate your account and keep it secure.
• To process uploaded images with OCR and generate translations.
• To analyze usage patterns and improve the user experience.

We share data with the following third-party providers only as needed to operate the service:

• Vercel — hosting and serverless infrastructure.
• Cloudflare — DNS, CDN, and DDoS protection.
• DeepSeek API — AI-powered translation and language analysis. Extracted text from your uploads is sent to DeepSeek for processing; no images are shared.
• Google Analytics (via GTM) — anonymized usage analytics.

We do not sell your personal data to any third party.

We retain your account data and uploaded content for as long as your account is active. If you delete your account, your personal data and uploaded images will be removed from our systems within 30 days. Aggregated, anonymized analytics data may be retained indefinitely.

Passwords are hashed using bcrypt and are never stored in plain text. All traffic is encrypted via HTTPS. Authentication tokens are issued as secure, HTTP-only JWTs. While we take reasonable measures to protect your data, no method of transmission over the internet is 100% secure.

You have the right to:

• Access the personal data we hold about you.
• Request correction of inaccurate data.
• Request deletion of your account and associated data.
• Withdraw consent for analytics cookies at any time via your browser settings.

To exercise any of these rights, contact us at the email below.

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated revision date. Continued use of the service after changes constitutes acceptance of the revised policy.
