Privacy Policy

1. Overview & Data Controller

Letters Font (https://lettersfont.com) is a free online font generator — a tool that converts plain text into decorative Unicode characters for use on Instagram, TikTok, WhatsApp, and other platforms. It is built and operated by the 345tool Team, an independent developer collective.

The defining characteristic of Letters Font's architecture is that all text processing happens inside your web browser. When you type text and select a font style, the Unicode character mapping runs in JavaScript on your device. Your typed text is never sent to any server for conversion.

2. How Client-Side Processing Works

Letters Font maps each character you type (A–Z, a–z, 0–9) to its decorative Unicode equivalent using a JavaScript mapping engine that runs entirely in your browser. For example, "A" → "𝐀" (Mathematical Bold Capital A, U+1D400). The mapping tables are embedded in a static JavaScript file (js/unicode-fonts.js) loaded once when you visit the page.

This means:

• Zero API calls for font conversion — no text is transmitted over the network during styling
• Zero server-side processing of your typed content
• Zero database storage of any user-generated text
• Fully functional offline after the initial page load — disconnect your internet and all 135+ font styles continue to work

You can verify this yourself. Open your browser's Developer Tools (F12), go to the Network tab, type text into Letters Font, and observe: no outbound requests carry your typed content.

3. What We Do NOT Collect

Letters Font does not collect, store, transmit, or process the following on any server:

• Personal identity: No registration, login, name, email address, phone number, or social media account is required to use any feature.
• Text input content: The text you type for font styling stays in your browser's memory (RAM) and is cleared when you close or refresh the tab.
• Styled text output: The converted Unicode text generated by the font engine exists only in your browser's DOM and memory.
• Clipboard content: Copied text uses the browser's built-in Clipboard API. The content never passes through our infrastructure.
• Payment or financial information: Letters Font is completely free. There is no payment system, no subscription, and no financial data collection of any kind.
• Behavioral profiling: No tracking pixels, no cross-site tracking cookies, no browser fingerprinting, no user behavior analytics beyond anonymized page-view counts (see Section 5).

4. What We DO Use

Two technologies store or transmit data when you use Letters Font:

5. localStorage: Favorites, Theme & Recent Styles

Letters Font uses your browser's localStorage API — a standard web platform feature that stores key-value data exclusively on your device. localStorage data is never automatically transmitted to any server; it remains in your browser's local storage directory.

The following keys are written to localStorage on your device:

• lettersfont_favs — A JSON array of font style IDs you have favorited. Stored so your favorites persist when you revisit the site.
• lettersfont_theme — A string ("light" or "dark") recording your display theme preference. Applied before page paint to prevent flashing.
• lettersfont_recent — A JSON array of the last 20 font style IDs you copied, enabling the "Recent" quick-access feature.

These values can be inspected and deleted at any time through your browser's Developer Tools (Application → Local Storage) or by clearing your browser data. They contain no personally identifiable information — only internal font style identifiers and a theme string.

6. Google Analytics (GA4)

Letters Font loads a minimal Google Analytics 4 measurement tag (ID: G-73PH7TNLBD) for aggregated traffic analytics. This provides high-level metrics: page view counts, approximate geographic distribution (country/city level from IP), browser and device categories, and traffic source categories (search, direct, referral).

What GA4 does NOT receive from Letters Font:

• Your typed text or styled font output
• Which font styles you view, favorite, or copy
• Your Instagram username, bio content, or any social media identifiers
• Any personally identifiable information beyond anonymized IP

GA4 data is processed by Google LLC under their standard Privacy Policy. You can opt out of GA4 entirely using browser privacy settings, ad-blocking extensions, or Google's Analytics Opt-out Browser Add-on.

7. Third-Party Resources Loaded

To render the interface, Letters Font loads the following external assets. These are static resources (fonts, icons) and an analytics script — no text content is shared with any of them:

• Google Fonts CDN — Typeface families: DM Sans, Space Grotesk, Inter, Sora, JetBrains Mono. Loaded via fonts.googleapis.com. Google's CDN may log the referring URL and browser metadata per their standard CDN operations.
• Google Fonts CDN — Material Symbols icon font (used for UI icons throughout the site).
• Google Tag Manager / GA4 — googletagmanager.com loads the GA4 measurement library. Configuration ID: G-73PH7TNLBD.

Letters Font does not embed: social media sharing widgets (all share buttons use static URLs), third-party comment systems, external login/authentication services, advertising networks, or any API endpoint that receives user-generated content.

8. Server Access Logs

Our hosting infrastructure maintains standard web server access logs for operational stability, security monitoring, and bandwidth management. These logs may record: your device's public IP address, browser User-Agent string, the specific URL requested, HTTP status code, response size, and timestamp.

These logs are standard across all websites, contain no personally identifiable information beyond a transient IP address, and are completely decoupled from any text input or font usage on the platform. Logs are typically retained for 30–90 days and automatically rotated.

9. GDPR, CCPA & COPPA Compliance

GDPR (EU/EEA): Letters Font processes no personal data on its servers. All text conversion is local to your browser. The only external data processing is GA4 anonymized page-view counting. You may exercise GDPR rights by contacting [email protected]. Since we store no user profiles or text histories, a data access request will confirm that no personal data is held.

CCPA (California): Letters Font does not sell, rent, or share personal information. No personal data is collected, stored, or monetized. There is no behavioral advertising, no cross-context behavioral tracking, and no data brokerage relationship of any kind.

COPPA (Children under 13): Letters Font does not knowingly collect any information from children under 13. The platform has no chat features, no user accounts, no comment sections, and no mechanism for users to submit personal data.

10. Policy Changes

This Privacy Policy may be updated to reflect changes in the tool's architecture, third-party dependencies, or regulatory requirements. The latest version is always available at https://lettersfont.com/privacy. The effective date at the top of this page indicates when the current version was published. Continued use of Letters Font after policy updates constitutes acceptance of the revised terms.
