Privacy Policy

Last updated: August 23, 2026

This Privacy Policy explains how TazzoGram ("TazzoGram," "we," "us," or "our") collects, uses, and protects information when you use the TazzoGram Diagram Studio application and related services (the "Service"), available at tazzogram.com and its subdomains.

1. Information we collect

We collect the minimum information needed to operate the Service:

• Account information. When you sign in with Google or register with an email address, we receive your email address and, for Google sign-in, basic profile information (name, profile image) provided by Google. We use your email domain to determine whether you qualify for free-tier or business-tier access.
• Diagram content you upload or create. Files and diagram code you open, edit, or generate in the Service are processed to provide the core functionality (format conversion, AI-assisted change requests, and rendering). See Section 3 for how this content is handled.
• Usage and technical data. We log basic technical information (IP address, browser type, timestamps, and general geographic region derived from IP address) to secure the Service, enforce rate limits, and default the interface language for Brazil-based visitors. We do not store your raw IP address long-term — country-level lookups are cached only as a hash of the IP address, for up to 30 days.
• Local browser storage. The Service uses your browser's local storage (not cookies) to remember preferences such as language selection and sidebar state. This data stays on your device and is not transmitted to us except where explicitly noted below.

2. How we use information

• To provide, maintain, and improve the Service.
• To authenticate you and enforce tier-based access limits (free, business, or approved accounts).
• To process diagram content through our AI-assisted conversion and change-request features.
• To communicate with you about your account, including approval notices for business-tier access.
• To detect, prevent, and address abuse, fraud, or security issues.

3. AI processing of diagram content

When you use TazzoGram's AI-assisted features (for example, requesting a change to a diagram, or translating page text), the relevant text is sent to Anthropic's Claude API for processing. This content is used only to generate the response shown to you and is not used by TazzoGram to train any model. Please review Anthropic's own privacy policy for how Claude API processes this data.

By default, your diagram's Glossary of business terms and obfuscation settings stay in your browser only and are never transmitted to our servers. If you explicitly opt in to GitHub-based storage for a diagram's Glossary, that data is written to a private repository under our GitHub organization instead, so that you can access it from another device or session.

4. Sharing of information

We do not sell your personal information. We do not share your information with third parties for their own marketing purposes. We may share information with:

• Service providers who help us operate the Service (hosting, email delivery, AI processing as described above), bound by confidentiality obligations.
• Authorities, if required by law, or to protect the rights, property, or safety of TazzoGram, our users, or others.

5. Data retention

We retain account and usage information for as long as your account is active or as needed to provide the Service, comply with legal obligations, resolve disputes, and enforce our agreements. You may request deletion of your account and associated data at any time (see Section 8).

6. Security

We use industry-standard measures to protect your information, including encrypted connections (HTTPS/TLS), access controls, and rate limiting. No method of transmission or storage is 100% secure, and we cannot guarantee absolute security.

7. International users

TazzoGram is used by visitors from Brazil and other countries. If you are located in the European Economic Area, the United Kingdom, Brazil, or another region with its own data protection law (such as the LGPD or GDPR), you may have additional rights over your personal data, including the right to access, correct, or delete it, and the right to object to certain processing. Contact us using the details in Section 8 to exercise these rights.
