Privacy Policy
At Zeugly, privacy is built directly into our client-side architecture.
Zero Personal Data Collection Policy
All data transformations, text formatters, image resizers, JWT decoders, PDF tools, and QR code scans execute 100% locally inside your web browser. We do not ask for, collect, store, or transmit any client data — including your name, mobile number, phone number, physical address, or email address.
1. Absolute Non-Collection of Personal Data
We operate under a strict zero-data collection rule:
- No Mobile / Phone Numbers: We never prompt for, require, store, or send phone or mobile numbers.
- No Names or Contact Details: We do not ask for or store names, email addresses, or physical addresses.
- No User Accounts: You do not need to register, log in, or provide any credentials to access any tool on Zeugly.
- No Client Databases: We maintain no backend user databases, CRM tracking systems, or personal profiling storage.
2. 100% Client-Side Browser Processing
Every tool on Zeugly runs locally inside your client web browser session using standard modern web APIs:
- Developer & Text Tools: JSON formatting, JWT decoding, Base64 conversion, text diffing, and hashing execute in local browser JavaScript memory.
- Image & PDF Utilities: Image resizing, SVG optimization, vector tracing, screenshot mockups, and PDF extraction process directly on your device CPU/GPU using standard Canvas and WebAssembly engines.
- Password & Hash Security: Cryptographic operations use operating system hardware randomness via
window.crypto.getRandomValues. - QR Code Scanner: Camera frames and uploaded image files are processed frame-by-frame entirely inside browser memory via client WebAssembly. Video feeds are never transmitted over any network.
3. Local Browser Storage
We only use standard browser localStorage to preserve non-sensitive UI settings (such as dark mode preferences or local draft state in our offline text editor). This data stays strictly on your device and is never sent to any remote server.
4. Security Audits & Domain Inspection
When inspecting QR codes, security checks and URL heuristic analysis execute directly inside your browser. If a domain reputation check is performed, only the hostname is evaluated — full paths, query parameters, or personal payload strings are never sent.
