Introduction
ConvertMastery (“we,” “us,” or “our”) operates convertmastery.com and related free online tools for file conversion, compression, PDF utilities, and related helpers. This Privacy Policy describes how we handle information when you visit our website or use our services.
By using ConvertMastery, you acknowledge this policy. If you do not agree, please discontinue use of the site. For cookies and advertising technologies, also see our Cookie Policy.
Information We Collect
Information you provide
- Account details — If you create an optional account, we may store your email address and display name so you can sign in and unlock advanced tool options.
- Support messages — Content you send via our contact form or email, including any details you share about a bug or request.
- Preferences — Settings you choose in the product (for example, output format or quality), typically stored in your browser session or local storage.
Information collected automatically
- IP address, approximate region, browser type, device type, and operating system
- Pages visited, referring URLs, and general interaction patterns
- Cookies and similar technologies, as described in our Cookie Policy
How We Use Information
We use the information above to:
- Operate, maintain, and improve ConvertMastery tools and pages
- Authenticate optional signed-in users and apply account-related preferences
- Diagnose errors, measure performance, and understand feature usage
- Display advertisements through partners such as Google AdSense
- Respond to support requests and enforce our Terms
- Comply with applicable law and protect the security of our services
We do not sell your personal information. We do not use the contents of your uploaded files for advertising profiling.
File Processing & Privacy
ConvertMastery is designed for on-the-fly processing. Depending on the tool:
- Some tools run entirely in your browser so your file may never leave your device for the core conversion step.
- Other tools briefly send a file to our servers (or a processing endpoint) only long enough to complete your request. Processed results are intended for immediate download.
We do not maintain a permanent “My Orders” style file archive of your uploads or outputs. You should download results before leaving the page. Do not upload highly sensitive documents unless you understand and accept the risks of transmitting them over the internet.
Google AdSense & Advertising
We use Google AdSense to fund free access to ConvertMastery. Google and its partners may use cookies and similar technologies to serve ads based on your visits to this site and/or other sites. This may include personalized (interest-based) advertising.
Opt out of personalized ads: Visit Google Ads Settings or aboutads.info. You can also manage cookies in your browser (see the Cookie Policy). Blocking ads or cookies may change how the site appears, but core tools remain available.
Google Analytics
We use Google Analytics to understand aggregate traffic—such as popular tools, session length, and general geography—so we can prioritize improvements. Analytics uses cookies. Learn more in the Google Privacy Policy.
Third-Party Services
Depending on the feature you use, we may rely on providers such as:
- Google AdSense (advertising)
- Google Analytics (usage analytics)
- Firebase (optional authentication)
- Hosting and infrastructure providers (for example, Vercel)
- Specialized APIs for tools such as WHOIS, breach lookups, or similar utilities
Those providers process data under their own policies. We encourage you to review them when relevant to your use of a specific tool.
Data Retention
- Accounts — Retained while your account remains active, and for a reasonable period afterward if needed for security or legal reasons.
- Support correspondence — Kept as needed to resolve your request and improve support quality.
- Logs & analytics — Retained for limited operational periods.
- Uploaded files — Not kept as a user-facing archive; server-side processing is transient and oriented toward completing your immediate request.
Your Rights
Depending on where you live, you may have rights to access, correct, delete, or restrict processing of personal data we hold about you, and to object to certain processing. To make a request, email contact@convertmastery.com. We may need to verify your identity before fulfilling a request.
Children’s Privacy
ConvertMastery is not directed to children under 13 (or the equivalent minimum age in your jurisdiction). We do not knowingly collect personal information from children. If you believe a child has provided us data, contact us and we will take appropriate steps.
Changes to This Policy
We may update this Privacy Policy to reflect product, legal, or operational changes. The “Last updated” date at the top of this page will change when we do. Continued use after an update means you accept the revised policy.
