Privacy Policy
How Zutilium handles browser processing, temporary server uploads, file cleanup, support messages and website data.
Information We Collect
Files and requests
Server tools receive the files and options you submit for processing. Network requests include technical information such as an IP address and browser headers; hosting services may keep request logs. Successful server conversions increase a tool usage counter. On selected tools we also count export attempts, successful outputs, download clicks, error categories and transfers to GIF Compressor by day. These counters contain no filenames, file contents or visitor identifiers.
Support messages
If you contact us, we store the name, email address, subject and message you submit so we can respond.
Browser storage
The Markdown editors save your draft and settings in your browser session storage so you can resume editing in the same session. These drafts are separate from files you send to the server for preview or export. Tools can be used without creating an account.
How We Use Your Information
We use the information we collect to improve and optimize our tools and services, monitor and analyze usage patterns, diagnose technical issues, and protect against abuse.
We do NOT use any collected information for advertising, marketing, creating user profiles, or selling to third parties.
File Processing
Sprite Sheet to GIF and .htpasswd Generator process their inputs in your browser without uploading those inputs to our conversion server. Server conversion tools temporarily store uploaded files and generated results on server disk. After a successful standard conversion, the original upload is scheduled for deletion after about one minute and output files after about ten minutes. Cleanup runs periodically, so deletion is not immediate and can take longer if cleanup is delayed. Download your result promptly; the server is not a file storage service.
Conversion and OCR engines read file contents to perform the task you request. The tool page explains the relevant processing mode and limitations. Files sent to server tools travel over the site's HTTPS connection.
Third-Party Services
Hosting infrastructure handles files submitted to server tools. Network tools such as Web Proxy connect to the external website you request. Links to third-party services have their own privacy practices.
Data Security
The public site uses HTTPS for data in transit. File size limits, format checks and scheduled cleanup help manage server processing.
Your Rights
You have the right to access, correct, delete, and restrict processing of your data. To exercise any of these rights, contact us using the information below.
Children's Privacy
Our tools are intended for general audiences and are not specifically directed at children under 13. We do not knowingly collect information from children. If you believe a child has provided information to us, please contact us and we will delete it.
Updates to This Policy
We may update this privacy policy from time to time. We will post the updated version on this page and update the "Last Updated" date. We encourage you to periodically review this policy.
