Privacy Policy
Last updated: July 31, 2026
1. Introduction
This Privacy Policy explains how Letry ("App", "we") collects, uses, stores, and protects user information, in accordance with Brazil's General Data Protection Law (LGPD - Law No. 13,709/2018).
2. Data we collect
We may collect the following categories of data:
- Account data: name, email, and information provided when you create your account;
- Captured content: images, pages, PDFs, or notes you scan with the camera or upload to the App, used to generate the read-aloud audio, summaries, and AI assistant responses;
- Usage data: interactions with the App, preferences (such as voice and reading speed), and activity logs;
- Device data: model, operating system, identifiers, and diagnostic information;
- Device permissions: camera access to scan text and, where applicable, access to your photo library;
- Location data: only when you explicitly authorize it.
3. How we use your data
We use the data we collect to:
- Convert captured content into audio, summaries, and AI assistant responses;
- Provide, maintain, and improve the App's features;
- Personalize your experience;
- Send important communications about the service;
- Prevent fraud and keep the platform secure;
- Comply with legal and regulatory obligations.
4. Data sharing
We do not sell your personal data. To function, the App sends captured content to third-party providers specialized in text recognition (OCR), voice synthesis, and artificial intelligence, which process this content solely to generate the requested reading, summaries, and responses. We may also share data with service providers that help us operate the App (e.g., hosting, analytics). In all cases, we require contractual confidentiality and security obligations, or sharing occurs only when required by law or court order.
Some of these providers may be located outside Brazil. In those cases, we adopt safeguards compatible with the LGPD to ensure an adequate level of protection for your data.
5. Storage and security
We adopt technical and organizational measures to protect your data against unauthorized access, loss, or alteration. Data is stored for as long as necessary to fulfill the purposes described in this policy or as required by law. Content you capture (images, text, and generated audio) may remain saved in your history within the App until you delete it or close your account.
6. Your rights
Under the LGPD, you have the right to:
- Confirm whether we process your data;
- Access, correct, or update your data;
- Request anonymization, blocking, or deletion of data;
- Withdraw consent at any time;
- Request the portability of your data.
To exercise your rights, contact us at oficialletryapp@gmail.com.
7. Cookies and similar technologies
We may use cookies and similar technologies to improve your experience, understand how the App is used, and personalize content. You can manage your preferences in your device or browser settings.
8. Children and teenagers
The App is not directed at children under 13. If we become aware that we have collected data from a minor without proper guardian consent, we will take steps to delete that information.
9. Changes to this policy
This Privacy Policy may be updated periodically. Material changes will be communicated through the App or by email before they take effect.
